[ Sen. 2, subscore: 2.00 ]: From paddy field observations in 2002 and 2004 , fenoxaprop-P-ethyl resistance in Chinese sprangletop ( Leptochloa chinensis ( L ) Nees ) has been studied using information collected from 11 sites in the Saphan-Sung district of Bangkok , Thailand . The resistant Chinese sprangletop was found in nine rice fields , whereas the susceptible Chinese sprangletop was found in only two rice fields . In greenhouse experiments , both fenoxaprop-P-ethyl-resistant and susceptible Chinese sprangletop from the same location were investigated for 50% growth reduction based on phytotoxicity , plant height and fresh and dry weight . The resistant Chinese sprangletop showed apparent resistance at 14-21 days after herbicide application at a rate of 21 . 1-337 . 6 g AI ha ( -1 ) . The resistance index of resistant Chinese sprangletop was 10-25 times higher than that of the susceptible Chinese sprangletop . In addition , Chinese sprangletop did not exhibit multiple resistance to oxadiazon , propanil and quinclorac . According to acetyl-CoA carboxylase ( ACCase ) assays , the level of ACCase specific activity in the resistant Chinese sprangletop was significantly higher than that in the susceptible Chinese sprangletop . Similarly , the ACCase activity of the resistant Chinese sprangletop was 10 times less sensitive to fenoxaprop-P-ethyl than that of the susceptible Chinese sprangletop , based on the I50 values . The present study of the mechanism responsible for resistance in the biotypes investigated indicated that there was a close association between the concentration-response at the whole-plant level and ACCase sensitivity to fenoxaprop-P-ethyl , and resistance to fenoxaprop-P-ethyl was conferred by a modified ACCase at the target site , as suggested by higher specific activity and less sensitivity to the herbicide .

[ Sen. 2, subscore: 3.00 ]: To support the continued use and the registration of monocrotophos , a field study was conducted at Calauan , Laguna , The Philippines , to assess exposure and the resulting health risk to 21 spraymen applying monocrotophos to rice crop by knapsack spraying during 3 consecutive days . The findings of the study were as follows : exposure of uncovered hands and of the skin of the back to the concentrate was visually observed during the filling , and respectively loading operations ; During spraying exposure from airborne diluted formulation occurred ; in addition contamination of the lower parts of the body took place because of direct contact with the sprayed crop ; Determination of the amount of the urinary metabolite dimethylphosphate excreted in 24 hours urine samples demonstrated absorption of monocrotophos into the body of the spraymen . The half-life of elimination of the urinary metabolite from the body was on average 18 hours ; No clinically significant inhibitions of whole blood or red blood cell cholinesterase activities were found , ie , 30% below baseline values . However , 8 of 21 spraymen had plasma cholinesterase levels below 50% of baseline values ; --No acute adverse health effects associated with the application of monocrotophos were observed , which was in accordance with the absence of clinically significant cholinesterase depressions . The conclusion of the study was that the use of monocrotophos under prevailing typical conditions in the Philippines , which varies from a frequency of one application per season to a maximum of 3 applications each on 3 consecutive days per week , and where label safety instructions are not necessarily observed , is not expected to pose an acute health risk under the prevailing conditions and practices , which includes filling , spraying and cleaning activities .

[ Sen. 1, subscore: 1.00 ]: We conducted a community-randomized controlled trial in Pakistan to determine the efficacy of indoor residual spraying with alphacypermethrin ( Fendona , Cyanamid , NJ , USA ) , applied at 25 mg/m2 , to prevent falciparum and vivax malaria . Wettable powder ( WP ) and suspension concentrate ( SC ) formulations were tested against an unsprayed control in an irrigated rice-growing area of Sheikhupura district , Punjab province . The study area of 180 km2 was divided into nine sectors , which were assigned at random to control , WP , or SC treatments in replicates of 3 . Sentinel villages were selected from each sector for entomological and disease monitoring . Malaria was monitored by fortnightly active case detection ( ACD ) and by cross sectional parasite surveys on schoolchildren . Mosquito populations were monitored by space spraying of rooms and by cattle-landing catches . The spray campaign took place in June 1997 and covered 96% of compounds . During the 7 months after spraying , the incidence of falciparum malaria was 95% lower and that of vivax malaria 80% lower in WP-sprayed than unsprayed sectors . Similar results were obtained for sectors sprayed with the SC formulation . Cross-sectional surveys gave estimates of efficacy comparable to those obtained by ACD .

The study area of 180 km2 was divided into nine sectors , which were assigned at random to control , WP , or SC treatments in replicates of 3 . Sentinel villages were selected from each sector for entomological and disease monitoring . Malaria was monitored by fortnightly active case detection ( ACD ) and by cross sectional parasite surveys on schoolchildren . Mosquito populations were monitored by space spraying of rooms and by cattle-landing catches . The spray campaign took place in June 1997 and covered 96% of compounds . During the 7 months after spraying , the incidence of falciparum malaria was 95% lower and that of vivax malaria 80% lower in WP-sprayed than unsprayed sectors . Similar results were obtained for sectors sprayed with the SC formulation . Cross-sectional surveys gave estimates of efficacy comparable to those obtained by ACD . Anopheles culicifacies was 80% less abundant and Astephensi , the predominant anopheline , was up to 68% less abundant in sprayed areas over the 7-month period . Reductions in anopheline parous rates indicated that the single-spray treatment was effective for the entire transmission season . Sprayed surfaces lacked odour , which contributed to the popularity of the campaign . Alphacypermethrin is a promising insecticide for the control of malaria in Pakistan and South Asia generally .

[ Sen. 6, subscore: 2.00 ]: Endotoxins from Bacillus thuringiensis ( Bt ) produced in transgenic pest-resistant Bt crops are generally not toxic to predatory and parasitic arthropods . However , elimination of Bt-susceptible prey and hosts in Bt crops could reduce predator and parasitoid abundance and thereby disrupt biological control of other herbivorous pests . Here we report results of a field study evaluating the effects of Bt sprays on non-target terrestrial herbivore and natural enemy assemblages from three rice ( Oryza sativa L ) fields on Luzon Island , Philippines . Because of restrictions on field-testing of transgenic rice , Bt sprays were used to remove foliage-feeding lepidopteran larvae that would be targeted by Bt rice . Data from a 546-taxa Philippines-wide food web , matched abundance plots , species accumulation curves , time-series analysis , and ecostatistical tests for species richness and ranked abundance were used to compare different subsets of non-target herbivores , predators , and parasitoids in Bt sprayed and water-sprayed ( control ) plots . For whole communities of terrestrial predators and parasitoids , Bt sprays altered parasitoid richness in 3 of 3 sites and predator richness in 1 of 3 sites , as measured by rarefaction ( in half of these cases , richness was greater in Bt plots ) , while Spearman tests on ranked abundances showed that correlations , although significantly positive between all treatment pairs , were stronger for predators than for parasitoids , suggesting that parasitoid complexes may have been more sensitive than predators to the effects of Bt sprays . Species accumulation curves and time-series analyses of population trends revealed no evidence that Bt sprays altered the overall buildup of predator or parasitoid communities or population trajectories of non-target herbivores ( planthoppers and leafhoppers ) nor was evidence found for bottom-up effects in total abundances of non-target species identified in the food web from the addition of spores in the Bt spray formulation . When the same methods were applied to natural enemies ( predators and parasitoids ) of foliage-feeding lepidopteran and non-lepidopteran ( homopteran , hemipteran and dipteran ) herbivores , significant differences between treatments were detected in 7 of 12 cases . However , no treatment differences were found in mean abundances of these natural enemies , either in time-series plots or in total ( seasonal ) abundance . Analysis of guild-level trajectories revealed population behavior and treatment differences that could not be predicted in whole-community studies of predators and parasitoids . A more conclusive test of the impact of Bt rice will require field experiments with transgenic plants , conducted in a range of Asian environments , and over multiple cropping seasons .

[ Sen. 9, subscore: 2.00 ]: The objectives of this study were to determine the long-term efficacy and safety of periarticular hyaluronic acid ( HA ) injections in acute lateral ankle sprain . A randomized , controlled , prospective trial in a primary sports medicine and emergency practice involved 158 competitive athletes who suffered an acute grade 1 or 2 lateral ankle sprain , and who were randomly assigned within 48 hours of injury . Patients were randomly assigned at baseline to periarticular injection with HA + standard of care ( rest , ice , elevation , and compression [ RICE ] ) or placebo injection ( PL ) + standard of care ( RICE ) treatment at baseline assessment and day 4 after injury . Follow-up was at 30 , 90 , and 712 days after treatment . Assessments at baseline and days 4 , 8 , 30 , 90 , and 712 included visual analogue scale ( VAS ) ( 0-10 cm ) pain on weight bearing and walking 20 m , patient global assessment of ankle injury ( 5-point categorical scale ) , patient satisfaction with treatment ( 5-point categorical scale ) , time to return to pain-free and disability-free sport , recurrent ankle sprain , total number of days missing from primary sport activity , and adverse events ( AEs ) . Time to intervention was 39 +/- 4 hours with no difference between groups . A significant reduction in VAS pain on both weight bearing and walking was observed at all follow-up assessments for HA compared with PL ( P < 0 . 001 ) . Time to pain-free and disability-free return to sport was 11 ( +/- 8 ) versus 17 ( +/- 8 ) days for HA and PL , respectively ( P < 0 . 05 ) . At 24 months , in the PL versus HA group , there were 2 versus 0 lower limb fractures , 16 versus 7 second ankle sprains ( P < 0 . 05 ) , 3 versus 1 third ankle sprains , and a significantly greater number of days missing primary sport activity ( 41 vs 21 ; P < 0 . 002 ) . Significantly greater patient satisfaction was also observed for HA versus PL at all follow-up assessments . No serious AEs were recorded throughout follow-up . Periarticular HA treatment for acute ankle sprain was highly satisfactory in the short and long term versus PL . This was associated with reduced pain , more rapid return to sport , fewer recurrent ankle sprains , fewer missed days from sport , and with few associated AEs to 24 months .

Assessments at baseline and days 4 , 8 , 30 , 90 , and 712 included visual analogue scale ( VAS ) ( 0-10 cm ) pain on weight bearing and walking 20 m , patient global assessment of ankle injury ( 5-point categorical scale ) , patient satisfaction with treatment ( 5-point categorical scale ) , time to return to pain-free and disability-free sport , recurrent ankle sprain , total number of days missing from primary sport activity , and adverse events ( AEs ) . Time to intervention was 39 +/- 4 hours with no difference between groups . A significant reduction in VAS pain on both weight bearing and walking was observed at all follow-up assessments for HA compared with PL ( P < 0 . 001 ) . Time to pain-free and disability-free return to sport was 11 ( +/- 8 ) versus 17 ( +/- 8 ) days for HA and PL , respectively ( P < 0 . 05 ) . At 24 months , in the PL versus HA group , there were 2 versus 0 lower limb fractures , 16 versus 7 second ankle sprains ( P < 0 . 05 ) , 3 versus 1 third ankle sprains , and a significantly greater number of days missing primary sport activity ( 41 vs 21 ; P < 0 . 002 ) . Significantly greater patient satisfaction was also observed for HA versus PL at all follow-up assessments . No serious AEs were recorded throughout follow-up . Periarticular HA treatment for acute ankle sprain was highly satisfactory in the short and long term versus PL . This was associated with reduced pain , more rapid return to sport , fewer recurrent ankle sprains , fewer missed days from sport , and with few associated AEs to 24 months .

[ Sen. 1, subscore: 1.00 ]: As has been previously discussed , the incidence and resultant associated disabilities of ankle sprains have been well documented in the literature . The staggering statistics on long-term disability show that there is no such thing as a simple ankle sprain . The degree of disability is related to the extent of the initial injury as well as the follow-up medical care provided . It is this fact that requires a complete understanding of the injury as well as a proper treatment and rehabilitation program . One of the reasons cited for the long-term disability or lack of consistently good results in treating ankle sprains is the lack of uniformity in treatment . One possible reason is the lack of agreement in diagnostic techniques as well as the end diagnosis of a particular grade of ankle sprain . If a sprain is managed correctly , resultant disability will be kept to a minimum . A proper rehabilitation program may be the most important factor in preventing chronic instability .

They show that malaria was already present on the Highlands in 1971 but at a low prevalence ; in 1980 when the "centres de nivaquinisation" were closed the number of cases increased by three times the progressive increase of the number of cases became exponential from 1986 to 1988 which was the peak of the epidemic ; malaria remained at a high level until the end of 1993 ; yearly DDT spraying since 1993 have decreased the number of malaria cases among the dispensary attendants by 90% . The epidemic peak of 1988 was well documented by the Pasteur Institute of Madagascar around Tananarive . Before the epidemic started it was observed a come back of An . funestus which had been previously eliminated of most of the villages by DDT spraying . More than an epidemic the malaria increase in 1988 was a reconquest by malaria of the land from which it had been eliminated in the years 1950 . This episode became dramatic because the lack of immunity of the population and the shortage of medicaments . The global warming which was advocated to explain the epidemic has no responsibility because the temperature on the Madagascar Highlands has not changed during the last 30 years . Also the cyclones do not seem to have played any role . It is very likely that the gradual decline of control measures , first DDT spraying , later drug distributions , had the main responsibility in the Highlands drama . Everywhere An . funestus reached a high level during the time where the parasite reservoir was rebuilding . They synergised each other . These findings should be taken in account in drawing the strategy planning for the next years .

[ Sen. 1, subscore: 1.00 ]: In this study , floral spray and floral dip were used to replace the vacuum step in the Agrobacterium-mediated transformation of a superoxide dismutase ( SOD ) gene into Arabidopsis . The transgene was constructed by using a CaMV 35S promoter to drive a rice cytosolic CuZnSOD coding sequence in Arabidopsis . The transgene construct was developed in binary vectors and mobilized into Agrobacterium . When Arabidopsis plants started to initiate flower buds , the primary inflorescence shoots were removed and then transformed by floral spray or floral dip . More than 300 transgenic plants were generated to assess the feasibility of floral spray used in the in planta transformation . The result indicates that the floral spray method of Agrobacterium can achieve rates of in planta transformation comparable to the vacuum-infiltration and floral dip methods . The floral spray method opens up the possibility of in planta transformation of plant species which are too large for dipping or vacuum infiltration .

Fecal samples from manure and whole dung pats were collected from each of the three separate pastures on the day that the animals were allocated and on days 1 , 3 , 6 , 9 and 12 afterwards . The fecal samples were tested for the presence of fungal colony forming units ( CFU ) , and the emergence of horn flies was observed in the dung pats . Significantly less ( P<0 . 01 ) adult horn flies were found in dung pats of the group treated with encapsulated fungi ( 11 . 7 ) than in those from the heifers treated with conidia in natura ( 27 . 9 ) or from the control group ( 29 . 5 ) . The fecal samples of the treated animals presented significantly higher numbers of M anisopliae CFUs then those from the untreated controls . We found that on day 9 fecal samples from animals given microencapsulated conidia had significantly higher CFUs than those from animals treated with conidia in natura . To assess adulticide activity , four heifers were sprayed with a suspension of 3 x 10 ( 10 ) conidial ( -1 ) of M anisopliae , and four control animals were sprayed with the same solution without conidial content .

[ Sen. 1, subscore: 1.00 ]: This paper reports a study of the distribution of organo-chlorine pesticides ( DDT and HCH ) between rice plants and the soil system by spraying before the heading stage at four different dosage levels--control , normal dosage ( 15 kg ha ( -1 ) of 6% HCH and 7 . 5 kg ha ( -1 ) of 25% DDT ) , double dosage and four times dosage . Soil and plant samples were taken respectively at the 1st h , 3rd , 10th , 20th , and 40th day after spraying and at the harvest time . The results indicate that less than 5% of HCH and 15% of DDT were absorbed by the surface of rice leaves for normal dosage . Most of both pesticides moved into the soil in solution after spraying . Compared with DDT , HCH was degraded and run off more easily . HCH residues in the surface soil layer ( 1-3 cm ) were already below 6 . 4 microg kg ( -1 ) at the mature stage , lower than Chinese Environmental Quality Standard for Agricultural Soils : HCH < 0 . 05 mg kg ( -1 ) . However DDT residues in the surface soil layer remained 172 microg kg ( -1 ) , higher than the national standard : DDT < 0 . 05 mg kg ( -1 ) . According to the test f OCP residues in rice seeds , it can be concluded that the OCP sprayed onto the surface of rice leaves can move into rice plants and accumulate in the seeds at the mature stage .

[ Sen. 17, subscore: 3.00 ]: The research is conducted in 3 cotton fields , 2 rice fields and 2 vegetable plantations . After filling and signing concerned forms , farmers are subjected to quantitative and qualitative questionnaires to generate data on : insecticides being used , the various doses applied for pests eradication , the frequency of treatments , the cost of treatments ( cost/hectare/year ) the origin of insecticides , the place of purchase , safety precautions and related health hazards . The results of this study have shown that the use of insecticides in agriculture is a clear fact . During treatments , insecticide residues get in contact with mosquito breeding sites where they diffuse into water and exercise a selection pressure on larvae . This partially explains the high levels of resistance recorded in with strains of Anopheles gambiae collected in agricultural settings under insecticides pressure . Pyrethroids and more specifically deltamethrin and cyfluthrin are the insecticides mainly used in studied localities . Bedrooms of farmers are used as storage place for half-used and un-used insecticides containers . For a proper management of insecticides , cotton and vegetable plantations farmers receive assistance from the ministry of rural development . Because of the importance of cotton production in the Republic of Benin , trainings on management of insecticides in agricultural settings are frequently organised by the ministry of rural development and are opened to farmers and their family members ( husbands , wives , children and relatives . . . ) . In the long run , the whole family learns and becomes very versant with the use of insecticides , spraying frequencies , spraying devices and spraying techniques .
[ Sen. 2, subscore: 1.00 ]: The use of insecticides in households and in agriculture has been incriminated in the emergence of insecticide resistance in insect vectors . For farming staff , the emergence of vector resistance is due to indoors spray of insecticides using aerosols and other low quality products in rural and urban settings against mosquitoes . On the other hand , public health specialists believe that the phenomenon of resistance could be due to massive use of insecticides in agriculture for field pests control . In Turkey , the implication of agricultural use of pesticides in the selection of vector resistance is clearly established . This study was framed to identify potential practices favouring the emergence of insecticide resistance in the Republic of Benin . Interviews and focus group discussions were organized with cotton , rice and vegetables farmers . The final aim of these surveys was to point out practices likely to favour the emergence of resistance . The research is conducted in 3 cotton fields , 2 rice fields and 2 vegetable plantations . After filling and signing concerned forms , farmers are subjected to quantitative and qualitative questionnaires to generate data on : insecticides being used , the various doses applied for pests eradication , the frequency of treatments , the cost of treatments ( cost/hectare/year ) the origin of insecticides , the place of purchase , safety precautions and related health hazards .

OUTCOMES MEASURES : Assessments at baseline and days 4 , 8 , 30 , and 90 included Visual Analogue Scale ( VAS ; 0-10 cm ) pain on weight bearing and walking 20 m , patient global assessment of ankle injury ( five-point categorical scale ) , patient satisfaction with treatment ( five-point categorical scale ) , time to return to pain-free and disability-free sport , and adverse events . Differences between groups were determined using an intent-to-treat analysis of variance . RESULTS : About 30% of the ankle sprains were "first" events , and no differences in clinical assessments with those presenting but not volunteering for the study ( n = 341 ) were observed . Time to intervention was 39 +/- 4 hours , with no difference between groups . No serious adverse events were recorded during the 8-day treatment period . No difference in concomitant treatment or physical therapy was observed between groups .

A non-operative functional treatment programme includes immediate use of RICE ( rest , ice , compression , elevation ) , a short period of immobilisation and protection with a tape or bandage , and early range of motion , weight-bearing and neuromuscular training exercises . Proprioceptive training on a tilt board after 3 to 4 weeks helps improve balance and neuromuscular control of the ankle . Treatment for grade III injuries is more controversial A comprehensive literature evaluation and meta-analysis showed that early functional treatment provided the fastest recovery of ankle mobility and earliest return to work and physical activity without affecting late mechanical stability .

A non-operative functional treatment programme includes immediate use of RICE ( rest , ice , compression , elevation ) , a short period of immobilisation and protection with a tape or bandage , and early range of motion , weight-bearing and neuromuscular training exercises . Proprioceptive training on a tilt board after 3 to 4 weeks helps improve balance and neuromuscular control of the ankle . Treatment for grade III injuries is more controversial A comprehensive literature evaluation and meta-analysis showed that early functional treatment provided the fastest recovery of ankle mobility and earliest return to work and physical activity without affecting late mechanical stability . Functional treatment was complication-free , whereas surgery had serious , though infrequent , complications . Functional treatment produced no more sequelae than casting with or without surgical repair . Secondary surgical repair , even years after an injury , has results comparable to those of primary repair , so even competitive athletes can receive initial conservative treatment . Sequelae of lateral ligament injuries are common . After conservative or surgical treatment , 10 to 30% of patients have chronic symptoms , including persistent synovitis or tendinitis , ankle stiffness , swelling , pain , muscle weakness and giving-way .

[ Sen. 4, subscore: 1.00 ]: Propanil is widely used as a postemergence herbicide in rice . Because it is typically applied aerially , there is a potential for propanil to drift into and around homes of those living adjacent to rice fields . Propanil has been shown to be immunotoxic in rodent models . The objective of this study was to measure the levels of propanil to which families living adjacent to aerially sprayed rice fields may be exposed . Air levels were sampled by actively and passively collecting propanil in and around the homes of volunteer families living in close proximity to rice fields sprayed with propanil . Homes ranged from 73 m to 113 m from treated rice fields . Sampling was conducted in the home , adjacent to the home ( within 5 m of the home ) , 30 m from the home , and at the edge of the rice field . Concentrations were determined via gas chromatography/mass spectroscopy . Propanil levels adjacent to the homes ranged from nondetectable to 1 , 106 . 4 microg per 400 cm2 collection surface ( 2 . 0 microg detection limit ) . Wind direction and wind velocity were the primary determinants of propanil drift . At sites where the prevailing wind was blowing away from the home , no propanil was detected except at the edge of the field . Distance from the edge of the rice field also influenced the amount of drift with higher levels measured at 30 m from the house than adjacent to the house . No propanil vapor was detected on absorbent media sampled in and around the homes .

[ Sen. 2, subscore: 1.00 ]: OBJECTIVE : Low-level laser therapy ( LLLT ) has been used for the last few years to treat sports injuries . The purpose of this study was to compare three therapeutic protocols in treating edema in second degree ankle sprains that did not require immobilization with a splint , under placebo-controlled conditions . MATERIALS AND METHODS : Forty-seven soccer players with second degree ankle sprains , selected at random , were divided into the following groups : The first group ( n = 16 ) was treated with the conventional initial treatment ( RICE , rest , ice , compression , elevation ) , the second group ( n = 16 ) was treated with the RICE method plus placebo laser , and the third group ( n = 15 ) was treated with the RICE method plus an 820-nm GaA1As diode laser with a radiant power output of 40 mW at 16 Hz . Before the treatment , and 24 , 48 , and 72 h later , the volume of the edema was measured . RESULTS : A three by three repeated measures ANOVA with a follow up post hoc test revealed that the group treated with the RICE and an 820-nm GaA1As diode laser presented a statistically significant reduction in the volume of the edema after 24 h ( 40 . 3 +/- 2 . 4 mL , p < 0 . 01 ) , 48 h ( 56 . 4 +/- 3 . 1 mL , p < 0 . 002 ) , and 72 h ( 65 . 1 +/- 4 . 4 mL , p < 0 . 001 ) .

[ Sen. 7, subscore: 1.00 ]: REFERENCE : Bleakley C , McDonough S , MacAuley D The use of ice in the treatment of acute soft-tissue injury : a systematic review of randomized controlled trials . Am J Sport Med . 2004 ; 32 : 251-261 . CLINICAL QUESTION : What is the clinical evidence base for cryotherapy use?DATA SOURCES : Studies were identified by using a computer-based literature search on a total of 8 databases : MEDLINE , Proquest , ISI Web of Science , Cumulative Index to Nursing and Allied Health ( CINAHL ) on Ovid , Allied and Complementary Medicine Database ( AMED ) on Ovid , Cochrane Database of Systematic Reviews , Cochrane Database of Abstracts of Reviews of Effectiveness , and Cochrane Controlled Trials Register ( Central ) . This was supplemented with citation tracking of relevant primary and review articles . Search terms included surgery , orthopaedics , sports injury , soft it issue injury , sprains and strains , contusions , athletic injury , acute , compression , cryotherapy , ice , RICE , andcold . STUDY SELECTION : To be included in the review , each study had to fulfill the following conditions : be a randomized , controlled trial of human subjects ; be published in English as a full paper ; include patients recovering from acute soft it issue or orthopaedic surgical interventions who received cryotherapy in inpatient , outpatient , or home-based treatment , in isolation or in combination with placebo or other therapies ; provide comparisons with no treatment , placebo , a different mode or protocol of cryotherapy , or other physiotherapeutic interventions ; and have outcome measures that included function ( subjective or objective ) , pain , swelling , or range of motion . DATA EXTRACTION : The study population , interventions , outcomes , follow-up , and reported results of the assessed trials were extracted and tabulated . The primary outcome measures were pain , swelling , and range of motion . Only 2 groups reported adequate data for return to normal function . All eligible articles were rated for methodologic quality using the PEDro scale . The PEDro scale is a checklist that examines the believability ( internal validity ) and the interpretability of trial quality . The 11-item checklist yields a maximum score of 10 if all criteria are satisfied . The intraclass correlation coefficient and kappa values are similar to those reported for 3 other frequently used quality scales ( Chalmers Scale , Jadad Scale , and Maastricht List ) . Two reviewers graded the articles , a method that has been reported to be more reliable than one evaluator .

Two reviewers graded the articles , a method that has been reported to be more reliable than one evaluator . MAIN RESULTS : Specific search criteria identified 55 articles for review , of which 22 were eligible randomized , controlled clinical trials . The articles scores on the PEDro scale were low , ranging from 1 to 5 , with an average score of 3 . 4 . Five studies provided adequate information on the subjects baseline data , and only 3 studies concealed allocation during subject recruitment . No studies blinded their therapists administration of therapy , and just 1 study blinded subjects . Only 1 study included an intention-to-treat analysis . The average number of subjects in the studies was 66 . 7 ; however , only 1 group undertook a power analysis . The types of injuries varied widely ( eg , acute or surgical ) . No authors investigated subjects with muscle contusions or strains , and only 5 groups studied subjects with acute ligament sprains . The remaining 17 groups examined patients recovering from operative procedures ( anterior cruciate ligament repair , knee arthroscopy , lateral retinacular release , total knee and hip arthroplasties , and carpal tunnel release ) . Additionally , the mode of cryotherapy varied widely , as did the duration and frequency of cryotherapy application . The time period when cryotherapy was applied after injury ranged from immediately after injury to 1 to 3 days postinjury . Adequate information on the actual surface temperature of the cooling device was not provided in the selected studies . Most authors recorded outcome variables over short periods ( 1 week ) , with the longest reporting follow-ups of pain , swelling , and range of motion recorded at 4 weeks postinjury . Data in that study were insufficient to calculate effect size . Nine studies did not provide data of the key outcome measures , so individual study effect estimates could not be calculated . A total of 12 treatment comparisons were made . Ice submersion with simultaneous exercises was significantly more effective than heat and contrast therapy plus simultaneous exercises at reducing swelling .

A total of 12 treatment comparisons were made . Ice submersion with simultaneous exercises was significantly more effective than heat and contrast therapy plus simultaneous exercises at reducing swelling . Ice was reported to be no different from ice and low-frequency or high-frequency electric stimulation in effect on swelling , pain , and range of motion . Ice alone seemed to be more effective than applying no form of cryotherapy after minor knee surgery in terms of pain , but no differences were reported for range of motion and girth . Continuous cryotherapy was associated with a significantly greater decrease in pain and wrist circumference after surgery than intermittent cryotherapy . Evidence was marginal that a single simultaneous treatment with ice and compression is no more effective than no cryotherapy after an ankle sprain . The authors reported ice to be no more effective than rehabilitation only with regard to pain , swelling , and range of motion . Ice and compression seemed to be significantly more effective than ice alone in terms of decreasing pain . Additionally , ice , compression , and a placebo injection reduced pain more than a placebo injection alone . Lastly , in 8 studies , there seemed to be little difference in the effectiveness of ice and compression compared with compression alone . Only 2 of the 8 groups reported significant differences in favor of ice and compression . CONCLUSIONS : Based on the available evidence , cryotherapy seems to be effective in decreasing pain . In comparison with other rehabilitation techniques , the efficacy of cryotherapy has been questioned . The exact effect of cryotherapy on more frequently treated acute injuries ( eg , muscle strains and contusions ) has not been fully elucidated . Additionally , the low methodologic quality of the available evidence is of concern .

Any preventive programme involving generalised cover in the highlands will require very substantial logistical support . We used multicriteria evaluation , by the method of weighted linear combination , as basis for improved targeting of actions by determining priority zones for intervention . RESULTS : Image analysis and field validation showed the accuracy of mapping rice fields to be between 82 . 3% and 100% , and the Kappa coefficient was 0 . 86 to 0 . 99 . A significant positive correlation was observed between the abundance of the vector Anopheles funestus and temperature ; the correlation coefficient was 0 . 599 ( p < 0 . 001 ) . A significant negative correlation was observed between vector abundance and human population density : the correlation coefficient was -0 . 551 ( p < 0 . 003 ) . Factor weights were determined by pair-wise comparison and the consistency ratio was 0 . 04 . Risk maps of the six study zones were obtained according to a gradient of risk . Nine of thirteen results of alert confirmed by the Epidemiological Surveillance Post were in concordance with the risk map . CONCLUSION : This study is particularly valuable for the management of vector control programmes , and particularly the reduction of the vector population with a view to preventing disease . The risk map obtained can be used to identify priority zones for the management of resources , and also help avoid systematic and generalised spraying throughout the highlands : such spraying is particularly difficult and expensive . The accuracy of the mapping , both as concerns time and space , is dependent on the availability of data .

[ Sen. 3, subscore: 1.00 ]: BACKGROUND : Brown rice is unpolished rice with immeasurable benefits for human health . Brown rice ( BR ) and pre-germinated brown rice ( PGBR ) are known to contain various functional compounds such as gamma-oryzanol , dietary fibre and gamma-aminobutyric acid ( GABA ) . In the present study , the experimental diets containing BR and PGBR ( 24 , 48 h pre-germination ) were used to investigate the influence of pre-germination time of brown rice on blood cholesterol in Sprague-Dawley male rats . RESULTS : Hypercholesterolaemia and elevation of LDL-cholesterol were successfully ameliorated by the experimental diets containing BR and PGBR ( 24 and 48 h pre-germination ) . As compared to the control sample , the pre-germination time had a significant ( P < 0 . 05 ) effect on blood cholesterol of Sprague-Dawley male rats . It was also found that the significantly ( P < 0 . 05 ) better effect on lipid profile of hypercholesterolaemic rats was observed by prolonging the pre-germination time . As compared to non-germinated brown rice , the germinated brown rice showed the higher cardio-protective effect on hypercholesterolaemic Sprague-Dawley male rats . CONCLUSION : The present study suggests that the changes of blood cholesterol can be mainly modulated by using the PGBR rather than BR . The prolonging of pre-germination time led to an increase in the bioactive components , thereby providing a more efficient functional diet affecting the high blood cholesterol . This study suggests that PGBR can be used instead of BR and polished rice in the human diet .

Brown rice ( BR ) and pre-germinated brown rice ( PGBR ) are known to contain various functional compounds such as gamma-oryzanol , dietary fibre and gamma-aminobutyric acid ( GABA ) . In the present study , the experimental diets containing BR and PGBR ( 24 , 48 h pre-germination ) were used to investigate the influence of pre-germination time of brown rice on blood cholesterol in Sprague-Dawley male rats . RESULTS : Hypercholesterolaemia and elevation of LDL-cholesterol were successfully ameliorated by the experimental diets containing BR and PGBR ( 24 and 48 h pre-germination ) . As compared to the control sample , the pre-germination time had a significant ( P < 0 . 05 ) effect on blood cholesterol of Sprague-Dawley male rats . It was also found that the significantly ( P < 0 . 05 ) better effect on lipid profile of hypercholesterolaemic rats was observed by prolonging the pre-germination time . As compared to non-germinated brown rice , the germinated brown rice showed the higher cardio-protective effect on hypercholesterolaemic Sprague-Dawley male rats . CONCLUSION : The present study suggests that the changes of blood cholesterol can be mainly modulated by using the PGBR rather than BR . The prolonging of pre-germination time led to an increase in the bioactive components , thereby providing a more efficient functional diet affecting the high blood cholesterol . This study suggests that PGBR can be used instead of BR and polished rice in the human diet .

[ Sen. 6, subscore: 2.00 ]: BACKGROUND : High resistance of brown planthopper ( BPH ) Nilaparvata lugens Stal to common insecticides is a challenge for control of the pest An alternative control strategy based on the combined application of fungal and chemical agents has been evaluated . RESULTS : Three gradient spore concentrations of oil-formulated Metarhizium anisopliae ( Metschnikoff ) Sorokin ( Ma456 ) were sprayed onto third-instar nymphs in five bioassays comprising the low buprofezin rates of 0 , 10 , 20 , 30 and 40 microg mL ( -1 ) respectively . Fungal LC ( 50 ) after 1 week at 25 degrees C and 14 : 10 h light : dark photoperiod decreased from 386 conidia mm ( -2 ) in the buprofezin-free bioassay to 40 at the highest chemical rate . Buprofezin ( LC ( 50 ) : 1647 , 486 and 233 microg mL ( -1 ) on days 2 to 4 ) had no significant effect on the fungal outgrowths of mycosis-killed cadavers at the low application rates . The fungal infection was found to cause 81% reduction in reproductive potential of BPH adults . In two 40 day field trials , significant planthopper ( mainly BPH ) control ( 54-60% ) was achieved by biweekly sprays of two fungal candidates ( Ma456 and Ma576 ) at 1 . 5 x 10 ( 13 ) conidia ha ( -1 ) and elevated to 80-83% by incorporating 30 . 8 g buprofezin ha ( -1 ) into the fungal sprays . CONCLUSION : The combined application of the fungal and chemical agents is a promising alternative strategy for BPH control .

[ Sen. 10, subscore: 2.00 ]: In 1953 , the Indian National Malaria Control Programme ( NMCP ) was started . Encouraged by the results , and the fact that insecticide resistance in vector species may evolve and become an obstacle , in 1958 a control programme was converted to the National Malaria Eradication Programme ( NMEP ) . By 1964 , malaria was eradicated from 88% of the area and it was in the advanced stage of spraying in the remaining parts . At that time , focal outbreaks that occurred in 1965 and increased in later years , could not be contained due to the shortages of DDT . As a result , large areas in consolidation and maintenance phases were reverted to the attack phase . Besides , the infrastructure in general health services was not adequate and mature enough to take up surveillance and vigilance . This produced a large number of secondary cases due to the re-introduction and relapse of malaria . Added to this was the problem of urban malaria , the control of which was the responsibility of local bodies . Malaria cases increased in towns , and started diffusing to the rural areas , due to inadequate staff and the shortages of malarial larvicidal oil ( MLO ) . Later , it turned out , that while it was technically feasible to eradicate malaria from 91% of the population , the strategy of indoor spraying of DDT to interrupt transmission did not succeed in 9 . 0% of the population , despite more than 12-14 years of regular spraying . During the years of resurgence , there was no research support to the programme , so that technical problems were not properly appreciated , understood and tackled . The reservoir of parasites that were present throughout the country started multiplying and spreading to newer areas due to the presence of vectors in high densities . Thus malaria resurged and re-established itself even in areas that were at one time freed from the disease . The analysis of the pattern of malaria resurgence revealed that malaria outbreaks preceded the true problem of insecticide resistance . It is noteworthy to mention that malaria resurgence occurred in towns where the control measures were non-insecticidal and in regions which were not under the influence of insecticide-resistant vectors . The study also revealed that resurgence occurred before the introduction of high-yielding varieties programme in the country , and had no relationship to either the cotton or rice growing or intensive agriculture .

A randomized controlled trial with blinded assessors was conducted to investigate the effect of a specific joint mobilization , the anteroposterior glide on the talus , on increasing pain-free dorsiflexion and 3 gait variables : stride speed ( gait speed ) , step length , and single support time . SUBJECTS : Forty-one subjects with acute ankle inversion sprains ( <72 hours ) and no other injury to the lower limb entered the trial METHODS : Subjects were randomly assigned to 1 of 2 treatment groups . The control group received a protocol of rest , ice , compression , and elevation ( RICE ) . The experimental group received the anteroposterior mobilization , using a force that avoided incurring any increase in pain , in addition to the RICE protocol . Subjects in both groups were treated every second day for a maximum of 2 weeks or until the discharge criteria were met , and all subjects were given a home program of continued RICE application . Outcomes were measured before and after each treatment . RESULTS : The results showed that the experimental group required fewer treatment sessions than the control group to achieve full pain-free dorsiflexion . The experimental group had greater improvement in range of movement before and after each of the first 3 treatment sessions . The experimental group also had greater increases in stride speed during the first and third treatment sessions .

Di ( 2-ethylhexyl ) adipate was also determined . Sixteen packed lunches and ten set lunches were analysed , and in all samples the concentration of di ( 2-ethylhexyl ) phthalate ( DEHP ) was the highest , at 0 . 80-11 . 8 mg/kg in packed lunches and 0 . 012-0 . 30 mg/kg in set lunches . The DEHP content of five packed lunches exceeded 1 . 85 mg , which is the EU tolerable daily intake ( TDI ) for a person of 50 kg body weight . Foodstuffs that were components of the packed lunches were taken from the factory at each step of preparation and phthalates were determined . For example , chicken contained 0 . 08 mg/kg DEHP when uncooked , 13 . 1 mg/kg after frying and 16 . 9 mg/kg after packing . Disposable PVC gloves used in the preparation of foods were apparently the source of high DEHP concentrations . The gloves used during cooking or packaging were sprayed with 68% ( w/w ) ethanol to sterilize them . PVC gloves from the factory contained 22 or 41% by weight of DEHP . To confirm the link with the contamination problem , samples of boiled rice , croquette and boiled dry radish were handled in the laboratory with PVC gloves containing 30% ( w/w ) DEHP .

The alcohol sprayed onto the gloves increased the migration of DEHP to 2 . 03 mg/kg in rice , 2 . 45 mg , kg in croquette , and 18 . 4 mg/kg in radish .
[ Sen. 13, subscore: 1.00 ]: Sixteen packed lunches and ten set lunches were analysed , and in all samples the concentration of di ( 2-ethylhexyl ) phthalate ( DEHP ) was the highest , at 0 . 80-11 . 8 mg/kg in packed lunches and 0 . 012-0 . 30 mg/kg in set lunches . The DEHP content of five packed lunches exceeded 1 . 85 mg , which is the EU tolerable daily intake ( TDI ) for a person of 50 kg body weight . Foodstuffs that were components of the packed lunches were taken from the factory at each step of preparation and phthalates were determined . For example , chicken contained 0 . 08 mg/kg DEHP when uncooked , 13 . 1 mg/kg after frying and 16 . 9 mg/kg after packing . Disposable PVC gloves used in the preparation of foods were apparently the source of high DEHP concentrations . The gloves used during cooking or packaging were sprayed with 68% ( w/w ) ethanol to sterilize them . PVC gloves from the factory contained 22 or 41% by weight of DEHP . To confirm the link with the contamination problem , samples of boiled rice , croquette and boiled dry radish were handled in the laboratory with PVC gloves containing 30% ( w/w ) DEHP . DEHP migration levels of 0 . 05 mg/kg in rice or 0 . 33 mg/kg in croquette , and 11 . 1 mg/kg in radish were found . The alcohol sprayed onto the gloves increased the migration of DEHP to 2 . 03 mg/kg in rice , 2 . 45 mg , kg in croquette , and 18 . 4 mg/kg in radish .

[ Sen. 4, subscore: 1.00 ]: Fusarium graminearum is the predominant pathogen causing fusarium head blight of cereals in North America . Fifteen Canadian isolates of Fusarium graminearum were highly diverse in terms of vegetative compatibility grouping ( VCG ) and varied for production of ergosterol and mycotoxin production in rice culture . Aggressiveness was assessed by scoring the disease severity incited in wheat spikes by each isolate . Two inoculation methods , single-floret injection and spray of entire spikes , were used to screen 4 wheat varieties for reaction to the F graminearum isolates . All isolates were of broadly similar aggressiveness , with disease severity ranging from 17 . 2 to 39 . 1 for single floret injection , and 39 . 1 to 69 . 0 for spray inoculation . Disease severity , ergosterol production , and mycotoxin development were not correlated . Using nitrate non-utilizing mutants the 15 isolates were grouped into 14 VCGs . Deoxynivalenol ( DON ) was produced by all isolates in rice culture , at levels between 0 . 2 and 249 ppm . 15-acetyldeoxynivalenol was produced by 14 of the 15 isolates at levels between 0 . 4 and 44 . 6 ppm . These results reveal a high level of diversity for several characteristics among F graminearum isolates from Canada .

[ Sen. 10, subscore: 1.00 ]: The possible regulation of senescence-initiated remobilization of carbon reserves in rice ( Oryza sativa L ) by abscisic acid ( ABA ) and cytokinins was studied using two rice cultivars with high lodging resistance and slow remobilization . The plants were grown in pots and either well-watered ( WW , soil water potential = 0 MPa ) or water-stressed ( WS , soil water potential = -0 . 05 MPa ) from 9 days after anthesis until they reached maturity . Leaf water potentials of both cultivars markedly decreased at midday as a result of water stress but completely recovered by early morning . Chlorophyll ( Chl ) and photosynthetic rate ( Pr ) of the flag leaves declined faster in WS plants than in WW plants , indicating that the water deficit enhanced senescence . Water stress accelerated starch remobilization in the stems , promoted the re-allocation of pre-fixed ( 14 ) C from the stems to grains , shortened the grain-filling period and increased the grain-filling rate . Sucrose phosphate synthase ( SPS , EC 2 . 4 . 1 . 14 ) activity was enhanced by water stress and positively correlated with sucrose accumulation in both the stem and leaves . Water stress substantially increased ABA but reduced zeatin ( Z ) + zeatin riboside ( ZR ) concentrations in the root exudates and leaves . ABA significantly and negatively , while Z+ZR positively , correlated with Pr and Chl of the flag leaves . ABA , not Z+ZR , was positively and significantly correlated with SPS activity and remobilization of pre-stored carbon . Spraying ABA reduced Chl in the flag leaves , and enhanced SPS activity and remobilization of carbon reserves . Spraying kinetin had the opposite effect . The results suggest that both ABA and cytokinins are involved in controlling plant senescence , and an enhanced carbon remobilization is attributed to an elevated ABA level in rice plants subjected to water stress .

METHODS AND RESULTS : Endophytic diazotrophic YS19 showed nitrogen-fixing activity in N-free medium , and produced four categories of phytohormones which were indole-3-acetic acid , abscisic acid , gibberellic acid and cytokinin in Luria-Bertani medium . Inoculation of YS19 improved the biomass of the 12-day-cultivated host rice seedlings by 63 . 4% on N-free medium or by 18 . 7% on N-supplemented medium . Spraying of YS19 cell culture onto the rice plants at the premilk stage enhanced the transportation of the photosynthetic assimilation product from the source ( flag leaves ) to the sink ( stachys ) significantly . The formation of the plant sink was obviously inhibited when YS19 cell culture was applied at the late milk stage . CONCLUSIONS : This research suggests that endophyte YS19 promotes host rice plant growth and affects allocations of host photosynthates . SIGNIFICANCE AND IMPACT OF THE STUDY : These findings suggested that YS19 possesses the potential for increasing rice production in field application . Meanwhile , a suitable plant growth stage must be selected for the foliar spraying of YS19 cell culture .

[ Sen. 3, subscore: 2.00 ]: A 3-year entomological study was carried out on the transmission of malaria in a village of 900 inhabitants in a rice-growing area of Burkina Faso . In the study area inhabitants use bed nets to protect themselves from mosquito bites . In the first year of the study , baseline data were collected ; in the second year , the village was divided in two parts and all the bed nets in the southern part were sprayed with deltamethrin ( 25 mg/m2 ) ; and in the third year , all the bed nets in both parts of the village were sprayed . The inoculation rate was estimated by hand collection of mosquitos on human volunteers who were not protected by bed nets . The overall inoculation rate in the first year was 55 infected bites per person and was higher in the southern than in the northern part of the village . During the second year the rate increased to 70 bites per person on average ( but was slightly lower than this in the southern part of the village ) . During the third year , the inoculation rate fell to three infected bites per year , ie , a reduction of 94% compared with the first year . This reduction arose primarily because of a marked decrease in the sporozoitic index and a lower density of vectors . Thus , use of pyrethroid-impregnated bed nets by all members of the community appears to be a major tool in preventing transmission of malaria .

[ Sen. 4, subscore: 1.00 ]: In the context of a large project for the socio-economic improvement of the Imbo area , measures were taken for the integration at all levels of malaria control : health centres for improvement of curative care ; hygiene and sanitation centres , communes and agricultural projects for vector control ; craftsmen , cooperatives and social centres for the manufacture and selling of impregnated bed-nets . The adopted strategy for malaria control results from preliminary epidemiological studies . The recommended measures are the improvement of medical care and vector control . The latter is based on indoor spraying of malathion , once a year . Malathion is only active during the period ( 2 months ) of highest transmission , which occurs at the end of the rainy season . Occasionally other insecticides are used . Impregnated bed-nets with deltamethrin and village draining are complementary methods . In villages of the rice-growing area with good participation of the community , vector control activities have a considerable impact on malaria prevalence . About 70% before the intervention , the prevalence does not exceed 10% in 1990 . High parasitaemia ( greater than 2000 troph . /microliters ) , and hence morbidity , decreased considerably ( 35% in 1983 to less than 5% in 1990 ) . In villages with poor community participation , the decrease of prevalence is less spectacular ( from 70% to 25% ) . Drains are not kept in repair and constitute new breeding places of vectors in the populated areas . The use of mosquito bed-nets is not common , a better information campaign should overcome this unpopularity .

[ Sen. 7, subscore: 1.00 ]: The strigolactones are internal and rhizosphere signalling molecules in plants that are biosynthesised through carotenoid cleavage . They are secreted by host roots into the rhizosphere where they signal host-presence to the symbiotic arbuscular mycrorrhizal ( AM ) fungi and the parasitic plants of the Orobanche , Phelipanche and Striga genera . The seeds of these parasitic plants germinate after perceiving these signalling molecules . After attachment to the host root , the parasite negatively affects the host plant by withdrawing water , nutrients and assimilates through a direct connection with the host xylem . In many areas of the world these parasites are a threat to agriculture but so far very limited success has been achieved to minimize losses due to these parasitic weeds . Considering the carotenoid origin of the strigolactones , in the present study we investigated the possibilities to reduce strigolactone production in the roots of plants by blocking carotenoid biosynthesis using carotenoid inhibitors . Hereto the carotenoid inhibitors fluridone , norflurazon , clomazone and amitrole were applied to rice either through irrigation or through foliar spray . Irrigation application of all carotenoid inhibitors and spray application of amitrole significantly decreased strigolactone production , Striga hermonthica germination and Striga infection , also in concentrations too low to affect growth and development of the host plant . Hence , we demonstrate that the application of carotenoid inhibitors to plants can affect S hermonthica germination and attachment indirectly by reducing the strigolactone concentration in the rhizosphere . This finding is useful for further studies on the relevance of the strigolactones in rhizosphere signalling . Since these inhibitors are available and accessible , they may represent an efficient technology for farmers , including poor subsistence farmers in the African continent , to control these harmful parasitic weeds .

[ Sen. 3, subscore: 2.00 ]: Accumulation of proline is trusted to be an adaptive response of plants against drought stress , and exogenous application of nitric oxide ( NO ) enhances proline accumulation in Cu-treated algae . In order to investigate whether NO works as a necessary signaling molecule in drought-induced proline accumulation in rice leaves , effects of drought stress on endogenous NO content and proline accumulation were studied in rice leaves , using sodium nitroprusside ( SNP , a NO donor ) and 2- ( 4-carboxyphenyl ) -4 , 4 , 5 , 5-tetramethylimidazoline-1-oxyl-3-oxide ( cPTIO , a NO scavenger ) . The results showed that drought treatment increased both endogenous NO and proline contents in rice leaves , while foliar spray of various concentrations of SNP failed to induce proline accumulation in the leaves of well-watered rice and foliar spray of cPTIO failed to inhibit proline accumulation in the leaves of drought-stressed rice . These results indicate that increase of endogenous NO is dispensable for proline accumulation in the leaves of rice under drought stress . Further studies indicate that exogenous application of NO alleviates drought-induced water loss and ion leakage by decreasing transpiration rate of rice leaves .

RESULTS : PHSNs with a shell thickness of 15 nm and a particle size of 80-100 nm were synthesised through a sol-gel route using nanosized calcium carbonate particles as templates . Simple immersing ( SI ) and supercritical fluid drug loading ( SFDL ) technologies were employed to load uniconazole into PHSNs with loading efficiencies of 22 and 26% respectively . The prepared uniconazole-loaded PHSNs ( UCZ-PHSNs ) by SI and SFDL both demonstrated sustained release properties , and the latter showed better controlled release ability with a slower release rate . Compared with free uniconazole , UCZ-PHSNs exhibited a weaker growth retardation effect in the early stage but more significant retardation ability in later stages for agar-cultured rice seedlings . For the rice that grew in clay , UCZ-PHSNs demonstrated a weaker plant height retardation effect than free uniconazole at the early jointing stage by foliar spraying , but exhibited a stronger retardation capacity than free uniconazole by being applied into soil before seedling transplantation . CONCLUSION : The results indicated that the prepared UCZ-PHSNs possessed good controlled-release properties and had improved retardation effects on rice growth . It is recommended that UCZ-PHSNs be applied into soil before seedling transplantation rather than administered by foliar spraying at the early jointing stage .

[ Sen. 3, subscore: 1.00 ]: The objective of the study was to corroborate or refute the hypothesis that farmers having a high intake of organic grown commodities have a high semen quality due to their expected lower level of dietary pesticides intake . Food frequency data and semen were collected from 256 farmers ( 171 traditional farmers and 85 organic farmers , overall participation rate : 32% ) who were selected from central registers . Each farmer delivered one semen sample before the spraying season started . The farmers were divided into three groups where the commodities from organic production contributed no ( N , 0% ) , medium ( M , 1-49% ) , or a high ( H , 50-100% ) proportion of the fruit and vegetables consumed . Farmers having a high relative intake of organically grown fruit and vegetables also had a high relative consumption of organically produced meat , milk , and bread , and differences were observed comparing the actual mean intake of single commodities , such as rice , potato , and pork meat . The current individual dietary intake of 40 pesticides was estimated using food frequencies and generalized serving size data in combination with data on pesticide concentrations in food commodities as obtained from the National Danish Food Monitoring Program . The estimated pesticide intake was significantly lower among farmers of group H , but for all three groups of farmers the average dietary intake of 40 pesticides was at or below 1% of the acceptable daily intake ( ADI ) except for the dithiocarbamates ( max = 0 . 21 microg/kg day = 2 . 2% ADI ) , methidathion , ( max = 0 . 01 microg/kg day = 1 . 4% ADI ) , and 2-phenylphenol ( max = 0 . 21 microg/kg day = 1 . 1% ADI ) . The median sperm concentration for the three groups of farmers was not significantly different ( p = 0 . 40 , median sperm concentration was N = 62 , M = 44 , and H = 75 million/ml ) . The group of men without organic food intake had a significant lower proportion of morphologically normal spermatozoa , but in relation to 14 other semen parameters no significant differences were found between the groups . Intake of 40 individual pesticides was correlated with four semen parameters ( concentration , percentage dead spermatozoa , percentage normal sperm heads , and motility [ VCL ] ) . Five significant correlations ( p value 0 . 01 ) were found among the 160 comparisons in relation to percentage dead spermatozoa : azinphos-methyl , carbaryl , chlorfenson , fenitrothion , and tetradifon . For all of them a lower percentage of dead spermatozoa were found in the groups with a high dietary intake of the specific pesticide .

[ Sen. 1, subscore: 1.00 ]: The foundational model to predict concentration of pesticides in the atmosphere outside of the sprayed area was developed using the results of measured concentration in the atmosphere , in reference to the atmospheric diffusion model utilized for the air pollution prediction model . The atmospheric diffusion model assumes that the applied area was a topographically flat farmland , that wind direction and wind speeds were constant , and the pesticide was constantly discharged from the emission line sources . Therefore the linear source plume model ( LSPLM ) was developed . The concentration in the atmosphere was predicted by assigning the property of the pesticides and various conditions of measurements of the model , and compared with the measured them , then the adaptability of the model was examined . As a result , the correlation between the measured value and the predicted value in paddy and forested areas was significant ( P < 0 . 01 ) although deviations in the order of tens were observed , the measured value and the predicted value were generally in agreement .

[ Sen. 7, subscore: 1.00 ]: Effects of methyl jasmonate ( MeJA ) on rice floret opening were investigated in seven cultivars or hybrid combinations covering various variety types . Intact or excised panicles , judged to have florets just before anthesis , were soaked in 4 x 10 ( -5 ) - 4 x 10 ( -3 ) M MeJA solutions for 2 min at different temperatures . The results indicated that MeJA significantly induced opening of rice florets within about 30 min , with the most rapid induction occurring just 6 min after treatment . Numbers of induced opening florets are correlated with MeJA concentrations . Higher concentrations of MeJA induced more florets . pH values had no influence on MeJA effect , but MeJA required less time and induced more florets at 34 degrees C than at 25 degrees C As far as we know , this is the first evidence that floret opening is induced by plant hormones . CO ( 2 ) evolution from panicles was also increased by MeJA treatment . Field experiments revealed that perfect flowering synchrony between the cytoplasmic male sterile ( CMS ) and restorer lines in hybrid seed production could be obtained by spraying MeJA solution on CMS line plants at the rate of 25 mg/m ( 2 ) . As a result , many more hybrid seeds were harvested .

[ Sen. 4, subscore: 1.00 ]: Rice bran oil ( RBO ) , when blended with safflower oil ( SFO ) at the ratio of 7 to 3 , has been shown to lower serum cholesterol in humans consuming cholesterol . The mechanism as to how this oil blend exerts its effect is not yet clear . This study examined the effect of cholesterol supplementation on the cholesterol-lowering ability of different RBO/SFO blends . Male Sprague Dawley rats ( 4 wk old ) were fed purified diets containing 10% fat with or without the addition of 0 . 5% cholesterol for 3 wk . The fat was either SFO or RBO alone , or the mixture of these two oils at the ratio of 7 : 3 ( 7S/3R ) , 5 : 5 ( 5S/5R ) , or 3 : 7 ( 3S/7R ) . Without cholesterol supplementation , there were no significant differences in the serum and liver total cholesterol levels among different dietary fats . However , the HDL cholesterol level of rats fed the RBO-containing diets ( especially in rats fed the 3S/7R diet ) was higher than that of rats fed the diet containing SFO alone . This resulted in an increase in the ratio of HDL/total cholesterol-a desirable outcome . Supplementation of the diets with 0 . 5% cholesterol significantly increased the cholesterol level in both the serum and the liver . Increasing the proportion of RBO in the diet further raised the total cholesterol level in the serum whereas it reduced liver cholesterol . Then , the specific effect of the 3S/7R mixture on the ratio of HDL/total cholesterol disappeared . These findings suggest that cholesterol supplemented at the level of 0 . 5% in this study masked the cholesterol-lowering effect of RBO . Smaller percentages of polyunsaturated fatty acid ( ie , 18 : 2n-6 ) in the RBO-containing diets than in the SFO diet might have reduced their ability to dispose the circulating serum cholesterol into the liver .

This elicitor activity of the cerebrosides showed the structural specificity as that for the induction of phytoalexins . Ceramides prepared from the cerebrosides by removal of glucose also showed the elicitor activity even in lower level compared to the cerebrosides . In field experiments , the cerebroside elicitors effectively protected rice plants against the rice blast fungus , an economically devastating agent of disease of rice in Japan .

Both theory and observation indicate that genetic heterogeneity provides greater disease suppression when used over large areas , though experimental data are lacking . Here we report a unique cooperation among farmers , researchers and extension personnel in Yunnan Province , China--genetically diversified rice crops were planted in all the rice fields in five townships in 1998 and ten townships in 1999 . Control plots of monocultured crops allowed us to calculate the effect of diversity on the severity of rice blast , the major disease of rice . Disease-susceptible rice varieties planted in mixtures with resistant varieties had 89% greater yield and blast was 94% less severe than when they were grown in monoculture . The experiment was so successful that fungicidal sprays were no longer applied by the end of the two-year programme . Our results support the view that intraspecific crop diversification provides an ecological approach to disease control that can be highly effective over a large area and contribute to the sustainability of crop production .

In addition to the determination of cortical Cd levels and histopathological assessment of kidneys , labeling indices ( LIs ) for proliferating cell nuclear antigen ( PCNA ) in the renal cortical tubular epithelium of Cd-treated rats were determined as a measure of regenerative activity . For comparison , the kidneys of rats given diets containing small to large amounts of CdCl2 up to 600 ppm for 4 months were similarly examined ( experiment 2 ) . Animals in experiment 1 demonstrated spontaneous chronic nephropathy and fluctuation in the tubular PCNA LI , but these findings were not correlated with renal Cd levels at 22 months . PCNA LI on the other hand , appeared to be linked to the severity of chronic nephropathy . In experiment 2 , levels of CdCl2 of 200 ppm or more clearly induced degeneration and apoptosis of proximal tubules with high correlations between renal Cd levels , PCNA LI , and the severity of tubular degeneration . The results demonstrated that , in contrast to high-dose Cd administration , treatment with 40 ppm or less for 22 months did not influence tubular regeneration as a component of nonspecific chronic nephropathy , suggesting that long-term oral administration of low levels of Cd does not injure renal tubules in female rats .

[ Sen. 7, subscore: 1.00 ]: Selenium ( Se ) content both in total and bioavailable forms were very low ( 25-35 and 9 . 5 micrograms/kg , respectively ) in waterlogged paddy soils in the central Yangtze River Delta . This was due to changes in geochemistry and the inherent properties of the parent materials of these lowland paddy soils . The very low Se content ( 23 micrograms/kg ) in the parent material resulted in low total Se content in the soil . The main chemical changes under long-term waterlogged conditions are depletion of molecular oxygen , decrease of redox potential , and reduction of Fe ( III ) to Fe ( II ) and SeO3 ( 2- ) to Se0 . This led to low availability of Se in soils , and subsequently low Se content ( 29 micrograms/kg ) in brown rice grain produced in this region . It has been suspected that low Se content in staple food might be one of the major reasons for a high infection rate of the intestine and stomach cancers and the higher death rate caused by these diseases in the region . Foliage spray of Na2SeO3 at early heading stage of rice plant growth improved the Se content of brown rice grain , hull , and straw , and would improve human and animal health .

[ Sen. 5, subscore: 1.00 ]: Studies of the effects of insect-resistant transgenic plants on beneficial insects have , to date , concentrated mainly on either small-scale "worst case scenario" laboratory experiments or on field trials . We present a laboratory method using large population cages that represent an intermediate experimental scale , allowing the study of ecological and behavioural interactions between transgenic plants , pests and their natural enemies under more controlled conditions than is possible in the field . Previous studies have also concentrated on natural enemies of lepidopteran and coleopteran target pests . However , natural enemies of other pests , which are not controlled by the transgenic plants , are also potentially exposed to the transgene product when feeding on hosts . The reduction in the use of insecticides on transgenic crops could lead to increasing problems with such nontarget pests , normally controlled by sprays , especially if there are any negative effects of the transgenic plant on their natural enemies . This study tested two lines of insect-resistant transgenic oilseed rape ( Brassica napus ) for side-effects on the hymenopteran parasitoid Diaeretiella rapae and its aphid host , Myzus persicae . One transgenic line expressed the delta-endotoxin Cry1Ac from Bacillus thuringiensis ( Bt ) and a second expressed the proteinase inhibitor oryzacystatin I ( OC-I ) from rice . These transgenic plant lines were developed to provide resistance to lepidopteran and coleopteran pests , respectively . No detrimental effects of the transgenic oilseed rape lines on the ability of the parasitoid to control aphid populations were observed . Adult parasitoid emergence and sex ratio were also not consistently altered on the transgenic oilseed rape lines compared with the wild-type lines .

Parasite fitness of mycelia and sclerotia formed on BTH-amended media was also reduced . When applied as soil drench or foliar spray , BTH inhibited both disease development on inoculated sheaths and its spread to the younger sheaths .

When applied through roots a protective effect of BTH was visible even with only a 1-h interval between application and inoculation . However , in the case of foliar application , protective effect was recorded only when the gap between application and inoculation was 24 h . BTH reduced the frequency of penetration by R solani , colonization of host it issue and spread of the hyphae from primary lesions to form secondary lesions . BTH induced swelling of hyphal tips on the sheath surface , formation of papillae , browning of penetrated epidermal cells and degeneration of intra-cellular hyphae colonizing epidermal and mesophyll cells . Therefore , the protective effect of BTH against sheath blight was due to combination of its host defence-inducing activity and its adverse effect on growth and vigor ( parasite fitness ) of the pathogen .

We studied epidemic malaria in Purworejo district , one of the three districts containing the Menoreh Hills . Between 1986 and 1995 , the annual parasite incidence ( API ) in Purworejo ranged from 2 to 11 cases per 1 , 000 residents per year and was typically approximately 5 per 1 , 000 . In 2000 the API was 44 . 5 . This sharp increase was confined to subdistricts in and around the Menoreh Hills and Dieng Plateau foothills . The primary vectors of malaria , those favoring steep , forested hillsides on Java , were Anopheles maculatus and Anopheles balabacensis . Deterioration of vector control activity , followed by a severe economic downturn in 1997 , may explain the epidemic . Malaria in the Menoreh Hills and lower Dieng Plateau threatens surrounding areas of rice paddy inhabited by Anopheles aconitus as well as a nearby coastal habitat where the even more efficient vector Anopheles sundaicus occurs in abundance . Most of the 130 million people living on Java never experienced the hyper and holoendemic malaria that occurred throughout most of the island before the effective DDT spraying and chloroquine treatment campaigns of the 1950s .

[ Sen. 9, subscore: 1.00 ]: Cell number and cell division activity in rice ( Oryza sativa ) endosperms are possibly regulated by cytokinin levels in the endosperm and its source in the roots . This study tried to find the possible correlations among them . Six rice genotypes were grown in nutrient solution . Two patterns of endosperm cell division , synchronous and asynchronous , were observed among the genotypes based on the cell division rate of superior and inferior spikelets . Contents of zeatin ( Z ) + zeatin riboside ( ZR ) were much higher than those of N6-isopentenyladenine ( iP ) and N6-isopentenyladenosine ( iPR ) in both endosperms and roots . Changes in Z + ZR levels in endosperms were significantly correlated with those in roots , and both were very significantly correlated with the cell division rate . Changes in iP + iPR contents in the roots were not significantly correlated with those in the endosperms and the cell division rate . When roots were treated with kinetin , endosperm cell number and grain weight were increased . Such enhancement was more significantly achieved by the root kinetin treatment than by spraying kinetin on leaves and panicles . The results suggest that the cell number and cell division activity in rice endosperms are regulated by cytokinin levels in the endosperm and that root-derived Z + ZR play a pivotal role .

At the same time , in the second experiment , the plots were alternately drained-flooded . At the end of water management , all plots of both experiments were drained and sprayed with herbicides to control the emerged red rice plants . In both years were applied : Propaquizafop 78 g a . i . ha-1 , Cycloxydim at 300 and 400 g a . i . ha-1 ; Dalapon at 15 . 300 Kg a . i . ha-1 ; Quizalofop-ethyl at 100 g a . i . ha-1 . Six days after the chemical treatments , all field plots were flooded 10 cm deep and three days later , an early variety of rice ( Loto ) was sown at 150 Kg ha-1 . Seedling emergence was reduced by lack of oxygen ( especially from seeds covered with soil in flooded condition ) . In alternately drained-flooded soil , the red rice emerged and developed from seeds located in the top 4-5 cm . In flooded condition , no red rice plants emerged from seeds at more than 1 cm depth . In both experiments , the density of red rice plants increased during the season in the untreated check and in the plots where treatments were ineffective or performed poorly . The best red rice control , both in submerged and in alternately drained-flooded soil , was obtained with Quizalofop-ethyl ( 100 g a . i . /ha ) , Cycloxydim ( 300 and 400 g a . i . ha-1 ) and Propaquizafop ( 78 g a . i . ha-1 ) .

[ Sen. 3, subscore: 1.00 ]: Japanese encephalitis ( JE ) remains endemo-epidemic in several countries in East , South-East and South Asia . The disease has been under control in Japan since the 1970s owing to mass immunization using mouse-brain-derived inactivated vaccine and to reduced vector mosquito populations . The vector density which was once reduced by wide spraying of insecticides in rice fields showed an increasing trend after the 1980s as a result of mosquito resistance . In the Republic of Korea , the number of JE cases showed a significant decrease after 1983 also because of mass immunization using mouse-brain-derived vaccine . On the other hand , large outbreaks of JE continued to occur in China , Viet Nam , Thailand , India , Nepal and Sri Lanka . In China , a hamster-kidney cell-derived vaccine was developed and used for human immunization . Besides human JE , the fatal outcome of equine JE is an economic problem in China . Current JE vaccine derived from mouse brain is highly purified and its safety and efficacy have been proved by field-tests as well as laboratory experiments . In spite of slight antigenic differences among JE virus isolates , JE vaccine produced by a classical Nakayama strain was effective in preventing overt JE in a field study in Thailand . The technology of mouse-brain-derived inactivated JE vaccine production was transferred from Japan to India , Thailand and Viet Nam . The production of JE vaccine in these countries is still on a pilot scale and insufficient for mass-immunization of susceptible target populations . ( ABSTRACT TRUNCATED AT 250 WORDS )

The transmission pattern differed markedly between the two zones . In the irrigated zone , the transmission of malaria was fairly constant over the seasons at a low level . In the non-irrigated zone , transmission was mostly below detection level during the dry season , whereas it was high toward the end of the rainy season . In the irrigated zone , high densities of mosquitoes were correlated with low anthropophily , low sporozoite indices and probably low survival rates . In the non-irrigated zone , mosquito densities were lower and these relationships were less pronounced . Differential use of mosquito nets in the two zones may have been an important factor in the observed differences in transmission . The presence of cattle may also have played an important role .

[ Sen. 6, subscore: 1.00 ]: OBJECTIVE : The cascade of physiological events underlying hypoxic-ischemic brain damage ( HIBD ) remains to be fully established . The perinatal brain shows both an increased tolerance to hypoxic-ischemic ( HI ) injury and a faster and more complete recovery than the adult . It is , therefore , important to understand the sequence of events following hypoxia and ischemia in young animals . The present study aimed to clarify the time-course of the activation of the mu-calpain , and the expression of c-Fos , c-Jun , HSP70 and HSP27 proteins following severe HI ( 2 h hypoxia ) and their relationship with each other . METHODS : A modified newborn rat model of HIBD that included a combination of hypoxia and ischemia as described by Rice was used . Forty-two postnatal 7-day-old Sprague-Dawley rats were randomly divided into seven groups ( 6 rats in each ) : 6 time-window groups and a normal control group . Samples were collected at 0 , 1 , 2 , 4 , 12 and 24 h after HI insults . The protein concentration was determined using a modified Bradford assay . mu-calpain activation , c-Fos , c-Jun , HSP70 and HSP27 expressions were observed respectively by Western blot from cortical and hippocampal samples . RESULTS : The cleavage of cytosolic mu-calpain was observed from both cortical and hippocampal samples in neonatal rats after HI . The ratio 76 : 80 of mu-calpain was increased significantly post-HI and reached a maximum at 24 h in cortex and at 12 h in hippocampus after HI . The expressions of c-Fos and c-Jun from both cortical and hippocampal samples in neonatal rats were up-regulated and peaked at 2 or 4 h after HI , demonstrating significant differences at 1 , 2 , 4 , and 12 h compared with that observed in the control ( P < 0 . 05 ) . When compared with that observed in cortex , the nuclear c-Fos expression from hippocampal samples was highly elevated at 2 , 4 and 12 h but significantly decreased at 24 h after HI ( P < 0 . 05 ) , while the nuclear c-Jun expression from hippocampal samples was highly elevated at 0 and 1 h but significantly decreased at 4 and 24 h after HI ( P < 0 . 05 ) . Similarly , the expressions of HSP70 and HSP27 from both cortical and hippocampal samples were up-regulated and reached a maximum at 12 or 24 h after HI , demonstrating significant differences at 12 or 24 h both in cortex and hippocampus for HSP70 , and at 24 h in cerebral cortex as well as at 12 and 24 h in hippocampus for HSP27 compared with the control ( P < 0 . 05 ) . Furthermore , in comparison with that observed in cortex , the HSP70 expression from hippocampal samples was highly elevated at 1 h , but significantly decreased at 4 , 12 and 24 h after HI ( P < 0 . 05 ) , while the HSP27 expression was permanently elevated in hippocampus after HI . CONCLUSION : The neuronal injury induced by HI insults appears to involve many ongoing and simultaneous mechanisms .

[ Sen. 1, subscore: 1.00 ]: The anticancer efficacy of tocotrienol-rich fraction ( TRF ) was evaluated during diethylnitrosamine ( DEN ) /2-acetylaminofluorene ( AAF ) -induced hepatocarcinogenesis in male Sprague-Dawley rats . TRF treatment was carried out for 6 months , and was started 2 weeks before initiation phase of hepatocarcinogenesis . Morphological examination of the livers from DEN/AAF rats showed numerous off-white patches and few small nodules , which were significantly reduced by TRF treatment . Cytotoxic damage by DEN/AAF was estimated by alkaline phosphatase ( ALP ) release into the plasma from the cell membranes . DEN/AAF caused a twofold increase in the activity of ALP in plasma as compared with normal control rats , and this increase was prevented significantly by TRF treatment . We observed an increase of 79% in liver ALP activity in DEN/AAF rats , which was further increased by another 48% after the administration of TRF . Hepatic activity of glutathione S-transferase ( GST ) was also increased ( 3 . 5-fold ) during the induction of hepatic carcinogenesis . Lipid peroxidation and low-density lipoprotein ( LDL ) oxidation increased threefold following initiation by DEN/AAF as compared with normal control rats . However , TRF treatment to DEN/AAF-treated rats substantially decreased ( 62-66% ) the above parameters and thus limited the action of DEN/AAF . We conclude that long-term intake of TRF could reduce cancer risk by preventing hepatic lipid peroxidation and protein oxidation damage due to its antioxidant actions .

[ Sen. 3, subscore: 1.00 ]: The dynamics of malaria transmission was studied comparatively in the villages of Zatta and Tiemelekro , central Cote dIvoire , from February 2002 to August 2003 . Prominent agroecosystems in these villages are irrigated rice growing and vegetable farming , respectively . Mosquitoes ( Diptera : Culicidae ) were collected on human bait at night and by pyrethrum knock-down spray sheet collections at four randomly selected sentinel sites in each village . In 2002 , for a total of 96 man-nights per village , 7716 mosquitoes were collected in Zatta and 3308 in Tiemelekro . In 2003 , with half the sampling effort , 859 and 2056 mosquitoes were collected in Zatta and Tiemelekro , respectively . Anopheles gambiae Giles s . l . was the predominant mosquito and the key malaria vector throughout , followed by An . funestus Giles . Anthropophily among adult female Anopheles exceeded 95% in both villages . Comparison between years revealed that the biting rate of An . gambiae s . l . in Zatta decreased several-fold from 49 . 3 bites per person per night ( b/p/n ) in 2002 to 7 . 9 b/p/n in 2003 ( likelihood ratio test ( LRT ) = 1072 . 66 ; P < 0 . 001 ) . Although the biting rate remained fairly constant in Tiemelekro , the difference between years was significant ( 16 . 1 vs 18 . 2 b/p/n ; LRT = 148 . 06 ; P < 0 . 001 ) . These observations were paralleled by a marked decrease in the infective rate of An . gambiae s . l . in Zatta ( 4 . 6-1 . 2% ) , and an increase in Tiemelekro ( 3 . 1-7 . 6% ) . Meanwhile , the entomological inoculation rate of An . gambiae s . l . decreased 21-fold in Zatta , from 789 to 38 infective bites per person per year ( ib/p/y ) , whereas it remained high in Tiemelekro ( 233 vs 342 ib/p/y ) . The interruption of irrigated rice growing in Zatta in 2003 , consequential to a farmers conflict over land , might be the underlying cause for the significant reduction in malaria transmission , whereas more stable conditions occurred in Tiemelekro .

[ Sen. 11, subscore: 1.00 ]: Integration of multiple copies of the introduced genes was the main reason of gene silencing which meant inhibition or loss of foreign gene expression in filial generations of transformants . In the present work , we compared the influences of maize Ubi-1 promoter and other promoters on copy number of transgenes in maize transgenic plants . Immature embryos from Zea mays L plants of sib-pollinated of A188 x H99 genotype were used as initial materials . Type I embryonic calluses derived from preculture of immature embryos were treated on N6 medium containing 0 . 6 mol/L sucrose for 3 approximately 5 hours and transformed via particle bombardment with PDS1000/He delivery system ( Bio-Rad ) . Bombarded calluses were treated with hyperosmotic N6 medium for 16 approximately 20 hours continuously . Then the cultures were transferred onto normal N6 medium and incubated at 26 degrees C in dark for two weeks and subsequently selected on N6 medium supplemented with 2 or 5 mg/L phosphinothricin ( PPT ) but without casamino acid for another two weeks . The calluses after selective culture were transferred onto hormone-free MS medium containing 2 or 5 mg/L PPT but without casamino acid , and incubated at 24 degrees C under 16 h illumination for plant regeneration . Regenerated plantlets over 2 cm in height were transferred to Magenta box containing 1/2 hormone-free MS medium . Plantlets over 8 cm in height were transplanted to soil . After growing for one week in greenhouse , the plants were sprayed with 250 mg/L PPT solution . Fertile transgenic maize plants were regenerated and confirmed by Southern blotting and histochemical localization of beta-glucuronidase ( GUS ) activity . Relations between promoter and copy number of transgenes in transformants were analyzed . Maize transgenic plants possessing an intact copy and another incomplete copy of beta-glucuronidase gene ( gus ) were obtained in case gus gene under the control of maize Ubi-1 promoter ( pUbi : GUS ) . Simultaneously the co-transformed phosphinothricin acetyltransferase gene ( bar ) controlled by CaMV 35S promoter in another plasmid ( p35S : BAR ) also existed with only one copy . When pDB1 and ( pUbi : in2 ) were cobombarded , the regenerated transgenic maize plant exhibited with only one copy of in2 gene too . It suggested that the copy number of transgenes in maize transformants was low if the transgenes controlled by maize Ubi-1 promoter . The possible reason might be that the foreign genes were integrated site-specifically via homologous recombination between Ubi-1 promoter and its endogenous sequences in maize genome , and two cotransformed plasmids had reconstructed as one intact molecule before integrating into maize chromosome . On the contrary , if p35S : BAR was cobom-barded with plasmid pAct : In1 containing rice Act-1 promoter ( without maize Ubi-1 promoter ) , the transgenic maize plants had 4 approximately 8 copies of bar gene . These results reflected that utilization of self gene promoter could reduce the copy number of the transgenes in transgenic plants of certain species itself and avoid the occurrence of gene silencing .

[ Sen. 3, subscore: 1.00 ]: The purpose of this work was to investigate the effect of different polysulfonate resins and direct compression fillers on physical properties of multiple-unit sustained-release dextromethorphan ( DMP ) tablets . DMP resinates were formed by a complexation of DMP and strong cation exchange resins , Dowex 50 W and Amberlite IRP69 . The tablets consisted of the DMP resinates and direct compression fillers , such as microcrystalline cellulose ( MCC ) , dicalcium phosphate dihydrate ( DCP ) , and spray-dried rice starch ( SDRS ) . Physical properties of tablets , such as hardness , disintegration time , and in vitro release , were investigated . A good performance of the tablets was obtained when MCC or SDRS was used . The use of rod-like and plate-like particles of Amberlite IRP69 caused a statistical decrease in tablet hardness , whereas good tablet hardness was obtained when spherical particle of Dowex 50 W was used . The plastic deformation of the fillers , such as MCC and SDRS , caused a little change in the release of DMP . A higher release rate constant was found in the tablets containing DCP and Dowex 50 W , indicating the fracture of the resinates under compression , which was attributable to the fragmentation of DCP . However , the release of DMP from the tablets using Amberlite IRP69 was not significantly changed because of the higher degree of cross-linking of the resinates , which exhibited more resistance to deformation under compression . In conclusion , the properties of polysulfonate resin , such as particle shape and degree of cross-linking , and the deformation under compaction of fillers affect the physical properties and the drug release of the resinate tablets .

The results show that the mercury-contaminated rice significantly increase the content of ACh in rat brain after exposure for 7 days . ACh maintained at a high level even after exposure for 30 days , but decreased significantly after exposure for 90 days . The changes of AChE represented an inverse trend compared with that of ACh . The coexisting selenium in rice exhibited antagonistic effects on both mercury accumulation and toxicity . The findings suggested that neurotoxic effects of environmental mercury contamination had been significantly represented after chronically dietary exposure . Further studies are needed to examine the relationship between the neurotransmitter level changes and the Alzheimers Disease ( AD ) .

The adhesive strength of film-coated tablets of fillers without drug was found to slightly decrease after storage . In contrast , the adhesive strength of drug-containing film-coated tablets significantly reduced , the degree of which was higher for Eudragit E100 than HPMC .

[ Sen. 3, subscore: 1.00 ]: A single-gene mutant ( rosette [ ros/ros ] ) in which shoot growth and development are inhibited was identified from a rapid cycling line of Brassica rapa ( syn campestris ) . Relative to normal plants , the mutant germinated slowly , had delayed or incomplete floral development , and reduced leaf , petiole , and internode growth . The exogenous application of GA ( 3 ) by foliar spray or directly to the shoot tip of rosette resulted in rapid flowering , bolting ( shoot elongation ) , and viable seed production . Shoots of rosette contained endogenous levels of total gibberellin ( GA ) -like substances ( ; Tan-ginbozu dwarf rice assay ) of about one-tenth of that of the normal rapid-cycling line of B rapa which consisted almost entirely of a very nonpolar , GA-like substance which yielded GA ( 1 ) and GA ( 3 ) upon mild acid hydrolysis . In a normal rapid-cycling B rapa line , the nonpolar putative GA ( 1 ) and GA ( 3 ) conjugates were present , but additionally , free GA ( 1 ) and GA ( 3 ) were abundant and identified by gas chromatography-mass spectrometry-selected ion monitoring . The quantities of free GA ( 1 ) and GA ( 3 ) in the normal line and in rosette were quantified by GC-MS-SIM using [ ( 2 ) H ( 2 ) ] GA ( 1 ) as an internal standard . Fourteen-day-old rosette and normal seedlings contained 5 . 3 and 23 . 2 ng GA ( 1 ) per plant , respectively . At day 21 the rosette plants contained 7 . 7 and 26 . 1 nanograms per plant of GA ( 1 ) and GA ( 3 ) , while normal plants contained 31 . 1 and 251 . 5 nanograms per plant , respectively . Thus , normal plants contained from four to ten times higher levels of total GA-like substances , GA ( 1 ) , or GA ( 3 ) , than rosette . The ros allele results in reduced GA level , yielding the rosette phenotype whose delayed germination and flowering , and reduced shoot growth responses indicate a probable role for endogenous GA ( 1 ) and GA ( 3 ) in the regulation of these processes in Brassica .

[ Sen. 3, subscore: 1.00 ]: BACKGROUND : Control of the Anopheline mosquito vectors of malaria by use of insecticides has been shown to impact on both morbidity and mortality due to this disease . Evidence of insecticide resistance in different settings necessitates surveillance studies to allow prompt detection of resistance should it arise and thus enable its management . Possible resistance by Anopheles arabiensis mosquitoes from Mwea rice irrigation scheme in Central Kenya to insecticides in the four classes of insecticides approved by WHO for indoor residual spraying was investigated . METHODS : Susceptibility to DDT ( an organochlorine ) , fenitrothion ( an organophosphate ) , bendiocarb ( a carbamate ) , lambdacyhalothrin and permethrin ( both pyrethroids ) was tested using standard WHO diagnostic bioassay kits . Bioassays were performed on non-blood fed mosquitoes one to three-day old . Knockdown was recorded every 10 min and mortality 24 h post-exposure was noted . RESULTS : Mortality 24 h post-exposure was 100% for all insecticides except for lambdacyhalothrin , which averaged 99 . 46% . Knockdown rates at 10 min intervals were not significantly different between the Mwea population and the susceptible KISUMU strain of Anopheles gambiae sensu stricto control . The KDT50 and KDT95 values for the Mwea population were either lower than those for the control or higher by factors of no more than 2 for most comparisons and compared well with those of An . gambiae sensu lato categorized as susceptible in other studies . CONCLUSION : These results suggest that the Mwea population of An . arabiensis is susceptible to all the insecticides tested . This implies that vector control measures employing any of these insecticides would not be hampered by resistance .

[ Sen. 2, subscore: 1.00 ]: Abscisic acid ( ABA ) is one of the important plant hormones , which plays a critical role in seed development and adaptation to abiotic stresses . The sensitivity of rice ( Oryza sativa L ) to exogenous ABA at seed germination and seedling stages was investigated in the recombinant inbred line ( RIL ) population derived from a cross between irrigated rice Zhenshan 97 and upland rice IRAT109 , using relative germination vigor ( RGV ) , relative germination rate ( RGR ) and leaf rolling scores of spraying ( LRS ) or culturing ( LRC ) with ABA as sensitivity indexes . The phenotypic correlation analysis revealed that only RGV at germination stage was positively correlated to ABA sensitivity at seedling stage . QTL detection using composite interval mapping ( CIM ) and mixed linear model was conducted to dissect the genetic basis of ABA sensitivity , and the single-locus QTLs detected by both methods are in good agreement with each other . Five single QTLs and six pairs of epistatic QTLs were detected for ABA sensitivity at germination stage . Eight single QTLs and five pairs of epistatic QTLs were detected for ABA sensitivity at seedling stage . Two QTLs were common between LRS and LRC ; and one common QTL was detected for RGV , LRS and LRC simultaneously . These results indicated that both single and epistatic loci were involved in the ABA sensitivity in rice , and the genetic basis of ABA sensitivity at seed germination and seedling stage was largely different .

From Agrobacterium-mediated transformation and hygromycin selective culture in vitro , hygromycin resistant calli and 36 transgenic rice ( Oryza sativa L ) plants were obtained . Histochemical assays of GUS activity showed that no expression was observed in the resistant calli and roots from transgenic rice if cultured under light , but after 24 h dark treatment there was strong GUS staining . Fluorimetric quantitative analysis indicated that GUS expression was organ-specific in transgenic rice . Without the dark treatment , GUS activity in roots and stems were about 7 and 3 times higher than in leaves in which GUS activity was only trace detected . After 24 h dark treatment , GUS activity in roots , stems and leaves of transgenic plants were all promoted and the largest increase was observed in leaves . Twenty-four hours after spraying with 5 mmol/L SA ( Salicylic Acid ) or 0 . 3 mol/L NaCl , GUS activity in leaves of the transgenic plants was 2 . 7 or 3 . 6 times respectively higher than untreated control .

[ Sen. 2, subscore: 1.00 ]: We conducted an entomological survey to determine the mosquito species diversity and abundance in relation to land use in the Mwea rice scheme , Kenya . Adult mosquitoes were collected by indoor spraying of houses and outdoors by CDC light traps in three villages representing planned ( Mbuinjeru ) and unplanned ( Kiamachiri ) rice agroecosystems and a non-irrigated agroecosystem ( Murinduko ) . During the 12-month sampling period , a total of 98 , 708 mosquitoes belonging to five genera and 25 species were collected . The five most common species collected during this study were Anopheles arabiensis Patton ( 52 . 5% ) , Culex quinquefasciatus Say ( 36 . 7% ) , Anopheles pharoensis Theobald ( 5 . 2% ) , Anopheles coustani Laveran ( 1 . 4% ) , and Anopheles funestus Giles ( 1 . 3% ) . Anopheles arabiensis , Cx quinquefasciatus , and An . pharoensis were more abundant in rice agroecosystems than in the non-irrigated agroecosystem , and in planned than in the unplanned rice agroecosystems . In contrast , An . funestus was more abundant in the non-irrigated agroecosystem . The mosquito species diversity ( H ) and evenness ( E ( H ) ) in the non-irrigated agroecosystem ( Shannon diversity Index , H = 1 . 507 , EH = 0 . 503 ) was significantly higher than in the rice agroecosystems ( H ) = 0 . 968 , E ( H ) = 0 . 313 , unplanned ; and H= 1 . 040 , E ( H ) = 0 . 367 planned ) . Results of lag cross correlation analysis revealed a strong relationship between rainfall and the abundance of An . arabiensis , and C quinquefasciatus in the non-irrigated agroecosystem but not in the rice agroecosystems . It is inferred from the data that different levels of habitat perturbations with regard to rice cultivation have different effects on mosquito diversity and abundance . This provides an understanding of how mosquito diversity is impacted by different habitat management and rice cropping strategies .

Rapid and transient expression of an elicitor-responsive gene , EL2 , was induced in the leaves of intact seedlings sprayed with the elicitor or in the roots and leaves of intact seedlings by immersing roots in the elicitor solution . Histochemical analysis indicated that EL2 was expressed in cells exposed to the elicitor of root and leaves . In seedlings treated with the elicitor for 1 d or longer , hyphal growth of rice blast fungus was significantly delayed , and an accumulation of auto-fluorescence around the infection site was observed . Two defense-related genes , PR-1 and PR-10 ( PBZ1 ) , were induced in a systemic and local manner by elicitor treatment , in correlation with the induction of resistance against rice blast fungus .

Two bentazon-lethal mutants 8077S and Norin8m are being utilized in developing new hybrid rice systems . When the male sterile lines are developed in such a mutant background , the problem of F1 seed contamination by self-seeds from the sterile lines can be solved by spraying bentazon at seedling stage . We first determined the sensitivity of the mutant plants to bentazon . Both mutants showed symptoms to bentazon starting from 100 mg/l , which was about 60-fold , lower than the sensitivity threshold of their wild-type controls . In addition , both mutants were sensitive to sulfonylurea-type herbicides . The locus for the mutant phenotype is bel for 8077S and bsl for Norin8m . Tests showed that the two loci are allelic to each other . The two genes were cloned by map-based cloning . Interestingly , both mutant alleles had a single-base deletion , which was confirmed by PCR-RFLP . The two loci are renamed bel ( a ) ( for bel ) and bel ( b ) ( for bsl ) . The wild-type Bel gene encodes a novel cytochrome P450 monooxgenase , named CYP81A6 .

T ( 1 ) plants with high rice chi11 and tlp protein expression levels were advanced to identify T ( 2 ) homozygotes by herbicide spray and subjected to further molecular analyses . T ( 3 ) progeny from one event ( E2 ) had stable integration and expression of the rice chi11 and tlp while those from the other events ( E1 and E3 ) showed stable integration only of tlp . The successful production of these lines overexpressing the antifungal chi and tlp proteins provides materials to test the effects of these genes on a variety of fungal diseases that attack barley and to serve as potential additional sources of disease resistance .

[ Sen. 9, subscore: 1.00 ]: Seven homozygous transgenic lines of two European commercial cultivars of rice ( Ariete ( A ) and Senia ( S ) ) , harbouring the cry1B or cry1Aa Bacillus thuringiensis ( Bt ) delta-endotoxin genes , were field evaluated for protection from striped stem borer ( SSB ) ( Chilo suppressalis ) damage during the 2001 and 2002 summer crop seasons in the Delta de lEbre region , Spain . The plant codon-optimized toxin gene was placed under the control of the promoter of either the constitutive ubi1 gene or the wound-inducible mpi gene from maize . Stable , high-level , insecticidal protein accumulation was observed throughout root , leaf and seed it issues of field-grown plants harbouring the cry1B ( lines A64 . 1 , A33 . 1 , A3 . 4 and S98 . 9 ) or cry1Aa ( lines S05 . 1 and A19 . 14 ) genes under the control of the ubi1 promoter . Conversely , no toxin was detected in unwounded vegetative it issues of the A9 . 1 line harbouring the cry1B gene controlled by the mpi promoter , indicating that natural environmental stresses did not trigger the activity of the wound-inducible promoter . However , the toxin accumulated at 0 . 2% total soluble proteins in A9 . 1 sheath it issue exhibiting brown lesions resulting from SSB damage . The agronomical traits and performance of the transgenic lines were generally comparable with parental controls , except in the two lines accumulating Cry1Aa , which exhibited a high frequency of plants non-true to type . Natural infestation was assisted with manual infestations of L2/L3 SSB larvae in border control plants surrounding the experimental plots , which served as a reservoir for the second-cycle SSB population . The observation of damage ( brown lesions and dead hearts ) during the crop season and dissection of plants at harvest stage revealed a range of protection amongst the transgenic lines , which was highly consistent with the level of toxin accumulation and with previous experience in greenhouse assays . Lines A3 . 4 and S05 . 1 were found to exhibit stable and full protection against SSB attacks , mediated by the accumulation of Cry1B and Cry1Aa toxin , respectively , which was comparable with that afforded by the spraying of chemical insecticides on control plants . The wound-induced A9 . 1 line exhibited a satisfactory level of protection , with a notably low level of penetration of SSB larvae in the stems , but higher external symptoms than constitutive lines , probably due to the time lag to benefit from the protective effect of Cry1B .

Electron spin resonance ( ESR ) was introduced to detect the species and the intensities of free radicals , using spin trap 5 , 5-dimethyl-1-pyrroline-N-oxide ( DMPO ) . The results showed that the mercury-contaminated rice significantly increased the levels of free radicals and MDA in rat brain at 7 days ( p < 0 . 05 ) . ESR spectrums showed that the principal spin adducts resulted from the trapping of alkyl free radical ( alphaH = 22 . 7 x 10 ( -4 ) T +/- 1 . 6 x 10 ( -4 ) T , alphaN = 15 . 5 x 10 ( -4 ) T +/- 0 . 5 x 10 ( -4 ) T ) , and hydroxyl radical Levels of free radicals and MDA increased slowly until after 90-day exposure period ( 83% , 100% ) . Element correlation analysis showed high correlations of mercury and selenium in the brain of rat fed with Wanshan rice , suggesting that the coexisting selenium in rice exhibited antagonistic effects on both mercury accumulation and toxicity . The slight increases of free radicals in rat brain at 7 , 20 and 30-day exposure periods should be related with the scavenger effect of Se .

WHO diagnostic tests showed high frequency of resistance in An . gambiae and Cx . quinquefasciatus to permethrin and DDT in three areas . This was consistent with the presence of target site insensitivity due to kdr mutation and to increased metabolism through enzymatic activity . Kdr was expressed in both M and S forms . However , less than 1% of An . gambiae or Cx . quiqnuefasciatus showed the presence of the Ace . 1 ( R ) mutation . Carbamate/OP resistance was present at higher frequency in Culex than in An . gambiae . Dieldrin resistance was present in both species at all four localities . A higher frequency of pyrethroid-resistance was found in An . gambiae mosquitoes collected in urban areas compared to those collected in rice growing areas . The expansion of vegetable growing within urban areas probably contributed to selection pressure on mosquitoes .

We also compared malaria transmission in areas with mixed and casiers plots . Larval collection was performed fortnightly with the standard WHO dipping technique . Adult Anopheles were collected both by pyrethrum spray and landing catches . During the dry season rice cultivation cycle , the larval density in the hors-casier was significantly higher than in the casier plots . The larval peak in the casier plots was considerably smaller than the one in the hors-casier . During the rainy season , no significant difference was observed between the two plot types . However , larval densities begin to rise approximately one month earlier in the casier then in the hors-casier plots , and continued to increase trough the rice development phases until the grain filling/maturation phase , declining thereafter . In contrast , in the hors-casier rice plots larval density increased throughout the rice development . This difference was not significantly reflected in the adult vector density and man biting rate . However , high relative frequencies of Anopheles funestus , survival and entomological inoculation rates of An . gambiae s . l . were observed in the mixed plot sector .

METHODS : Sprague Dawley rats were fed the mercury-contaminated rice produced from Wanshan area for 90 days . The antioxidant status and the free radicals in rat serum were evaluated . RESULTS : High mercury accumulation in organs of rats fed the mercury-contaminated rice confirmed the server pollution of mercury in Wanshan mining area . The intensity of electron spin resonance ( ESR ) signal increased by 87 . 38% in rats fed the rice from Wanshan compared with that in the control rats fed the rice from Shanghai , suggesting that chronic dietary consumption of rice from mercury mining area could induce an aggravation of free radicals . Feeding the mercury-contaminated rice was associated with significant decreases in the antioxidant enzymatic activities of superoxide dismutase ( SOD ) and glutathione peroxidase ( GSH-Px ) and concentration of serum nitric oxide ( NO ) , but it had no effect on serum nitric oxide synthase ( NOS ) activity . Feeding the mercury-contaminated rice raised the level of serum malonyldialdehyde ( MDA ) , indicating the occurrence of oxidative stress .

[ Sen. 4, subscore: 1.00 ]: OBJECTIVE : A recent study has suggested that hyperbaric oxygen ( HBO ) therapy administered within 3 hrs following hypoxic-ischemic brain damage ( HIBD ) may alleviate brain white matter damage ( WMD ) in neonatal rats . However it is unclear whether a delayed HBO therapy ( more than 3 hrs following HIBD ) has neuroprotective effects in neonatal rats . This study aimed to explore the effect of HBO therapy administered at different time points following HIBD on WMD in neonatal rats . METHODS : The HIBD model was prepared according to the Rice-Vannucci procedure in 7-day-old Sprague-Dawley rats . HBO therapy was administered at 3 , 6 , 12 , 24 or 72 hrs after HIBD , once daily for consecutive 7 days . T-maze test , the foot-fault test and the radial arm maze test were performed after 14 days of HIBD . Myelin basic protein ( MBP ) in the callositas and corpora striata was examined by immunohistochemical method 28 days after HIBD . RESULTS : The rats receiving HBO therapy at 3 , 6 and 12 hrs after HIBD performed significantly better in the T-maze test , the radial arm maze test and the foot-fault test than the untreated HIBD rats . There were no significant differences in the behavioral test results between the HBO-treated groups administered HBO at 24 and 72 hrs after HIBD and the untreated HIBD group . The MBP expression in the HBO-treated groups treated within 12 hrs after HIBD was significantly higher than that in the untreated HIBD group ( P < 0 . 05 ) . When the HBO therapeutic window was delayed to 24 hrs after HIBD , there were no significant differences in the MBP expression between the HBO-treated and the untreated HIBD groups . CONCLUSIONS : HBO therapy administered within 12 hrs following HIBD can alleviate brain WMD in neonatal rats , but the efficacy of HBO therapy administered 24 hrs after HIBD does not appear to be satisfactory .

[ Sen. 7, subscore: 1.00 ]: Plant transgenic technology has been widely utilized for engineering crops for trait improvements and for production of high value proteins such as pharmaceuticals . However , the unintended spreading of commercial transgenic crops by pollination and seed dispersal is a major concern for environmental and food safety . Simple and reliable containment strategies for transgenes are highly desirable . Here we report a novel method for creating selectively terminable transgenic rice . In this method , the gene ( s ) of interest is tagged with a RNA interference cassette , which specifically suppresses the expression of the bentazon detoxification enzyme CYP81A6 and thus renders transgenic rice to be sensitive to bentazon , a herbicide used for rice weed control . We generated transgenic rice plants by this method using a new glyphosate resistant 5-enolpyruvylshikimate-3-phosphate synthase ( EPSPS ) gene from Pesudomonas putida as the gene of interest , and demonstrated that these transgenic rice plants were highly sensitive to bentazon but tolerant to glyphosate , which is exactly the opposite of conventional rice . Field trial of these transgenic rice plants further confirmed that they can be selectively killed at 100% by one spray of bentazon at a regular dose used for conventional rice weed control . Furthermore , we found that the terminable transgenic rice created in this study shows no difference in growth , development and yield compared to its non-transgenic control . Therefore , this method of creating transgenic rice constitutes a novel strategy of transgene containment , which appears simple , reliable and inexpensive for implementation .

Rice was transformed with a plasmid that includes a Basta-resistance gene ( bar ) . After the Ds element is excised during transposition , bar becomes adjacent to the ubiquitin promoter , and the rice plant becomes resistant to the herbicide Basta . In principle , one can plant up to one million plants in the field and select those plants that survive after spraying with Basta . To test the utility of this system , 4 Ds starter lines were crossed with 14 different Ac plants , and many transposants were successfully identified after planting 134 , 285 F2 plants in the field .

Only two BPH-derived M anisopliae isolates from the Philippines ( ARSEF456 ) and Indonesia ( ARSEF576 ) killed > 50% of the nymphs . Both isolates were further bioassayed for time-concentration-mortality responses of the nymphs to the sprays of 19-29 , 118-164 and 978-1088 conidia mm ( -2 ) in repeated bioassays . The resultant data fitted a time-concentration-mortality model very well . Their LC ( 50 ) values were estimated as 731 and 1124 conidia mm ( -2 ) on day 7 and fell to 284 and 306 conidia mm ( -2 ) , respectively , on day 10 . CONCLUSION : The two M anisopliae isolates are potential biocontrol agents of BPH for further research .

[ Sen. 7, subscore: 1.00 ]: Imidacloprid has been used for many years to control planthopper Nilaparvata lugens ( Stal ) ( Homoptera : Delphacidae ) in China . To provide resistance assessment for the national insecticide resistance management program , we collected a total of 42 samples of the planthoppers from 27 locations covering eight provinces to monitor their dose responses and susceptibility changes to imidacloprid over an 11-yr period ( 1996-2006 ) . Results showed that most field populations maintained susceptibility from 1996 to 2003 except for a population from Guilin , Guangxi , in 1997 , which showed a low level of resistance to imidacloprid . However , surveys conducted in 2005 indicated that 16 populations from six provinces quickly developed resistance with resistance ratios ranging from 79 to 811 . The data collected in 2006 revealed that the resistance levels in 12 populations collected from seven different provinces decreased slightly ( RR = 107-316 ) , except the Tongzhou population ( Jiangsu Province ) , which developed 625-fold resistance . Dominant and intensive use of imidacloprid in a wide range of rice , Oryza savita L , growing areas might be a driving force for the resistance development . Migration of the insect also significantly boosted the resistance levels due to extensive and intensive use of imidacloprid in emigrating areas and continuous postmigration sprays of the chemical In addition , laboratory resistance selection using imidacloprid showed that resistance ratio increased to 14-fold after 27 generations , suggesting that quick resistance development might be associated with more frequent applications of the insecticide in recent years .

The results showed that exogenous SA induced the enhancement of the allelopathic potential of donor rice in suppressing target weed plants , and this inducing effect was SA dose and treatment time dependent . After foliar spraying SA , the inhibitory effect of PI312777 on barnyardgrass increased significantly , and the root vigor and superoxide dismutase ( SOD ) and perocidase ( POD ) activities of PI312777 increased , while its catalase ( CAT ) activity decreased . The reverse was true for the target weed barnyardgrass . At the same time , the phenylalanine ammonialyase ( PAL ) activity of PI312777 increased significantly , leading to an increase of the total content of phenols . Among the test concentrations of SA , 0 . 2 mmol x L ( -1 ) had the best inducing effect , under which , the relative expression quantity of ZB8 increased first and decreased then , with a peak at 24 hours after treatment .

[ Sen. 4, subscore: 1.00 ]: This article presents a toxicologically-based risk assessment strategy for identifying the individual components or fractions of a complex mixture that are associated with its toxicity . The strategy relies on conventional component-based mixtures risk approaches such as dose addition , response addition , and analyses of interactions . Developmental toxicity data from two drinking-water concentrates containing disinfection by-products ( DBP ) mixtures were used to illustrate the strategy . The results of this study showed that future studies of DBP concentrates using the Chernoff-Kavlock bioassay need to consider evaluating DBP that are concentrated more than 130-fold and using a rat strain that is more sensitive to chemically-induced pregnancy loss than Sprague-Dawley rats . The results support the planned experimental design of a multigeneration reproductive and developmental study of DBP concentrates . Finally , this article discusses the need for a systematic evaluation of DBP concentrates obtained from multiple source waters and treatment types . The development of such a database could be useful in evaluating whether a specific DBP concentrate is sufficiently similar to tested combinations of source waters and treatment alternatives so that health risks for the former may be estimated using data on the latter .

[ Sen. 8, subscore: 1.00 ]: ABSTRACT : BACKGROUND : Malaria transmission in most agricultural ecosystems is complex and hence the need for developing a holistic malaria control strategy with adequate consideration of socio-economic factors driving transmission at community level . A cross-sectional household survey was conducted in an irrigated ecosystem with the aim of investigating vector control practices applied and factors affecting their application both at household and community level . METHODS : Four villages representing the socio-economic , demographic and geographical diversity within the study area were purposefully selected . A total of 400 households were randomly sampled from the four study villages . Both semi-structured questionnaires and focus group discussions were used to gather both qualitative and quantitative data . RESULTS : The results showed that malaria was perceived to be a major public health problem in the area and the role of the vector Anopheles mosquitoes in malaria transmission was generally recognized . More than 80% of respondents were aware of the major breeding sites of the vector . Reported personal protection methods applied to prevent mosquito bites included ; use of treated bed nets ( 57% ) , untreated bed nets ( 35% ) , insecticide coils ( 21% ) , traditional methods such as burning of cow dung ( 8% ) , insecticide sprays ( 6% ) , and use of skin repellents ( 2% ) . However , 39% of respondents could not apply some of the known vector control methods due to unaffordability ( 50 . 5% ) , side effects ( 19 . 9% ) , perceived lack of effectiveness ( 16% ) , and lack of time to apply ( 2 . 6% ) . Lack of time was the main reason ( 56 . 3% ) reported for non-application of environmental management practices , such as draining of stagnant water ( 77% ) and clearing of vegetations along water canals ( 67% ) . CONCLUSION : The study provides relevant information necessary for the management , prevention and control of malaria in irrigated agro-ecosystems , where vectors of malaria are abundant and disease transmission is stable .

[ Sen. 16, subscore: 1.00 ]: The presence of the circumsporozoite protein of Plasmodium falciparum was determined using ELISA . RESULTS : Anopheles gambiae populations were dominated by the M form . However the S form occurred in relative important proportion towards the end of the rainy season with a maximum peak in October at 51% . Sporozoite rates were similar in both forms . The frequency of the Leu-Phe kdr mutation in the S form reached a fixation level while it is still spreading in the M form . Furthermore , the ace-1R mutation prevailed predominately in the S form and has just started spreading in the M form . The two mutations occurred concomitantly both in M and S populations . CONCLUSION : These results showed that the Vallee du Kou , a rice growing area formerly occupied mainly by M susceptible populations , is progressively colonized by S resistant populations living in sympatry with the former . As a result , the distribution pattern of insecticide resistance mutations shows the occurrence of both resistance mechanisms concomitantly in the same populations . The impact of multiple resistance mechanisms in M and S populations of An . gambiae on vector control measures against malaria transmission , such as insecticide-treated nets ( ITNs ) and indoor residual spraying ( IRS ) , in this area is discussed .

A 12-month entomological survey was conducted to determine the diversity of riceland mosquitoes and factors affecting their occurrence and distribution at 3 sites targeted for malaria vector control in Mwea , Kenya . Adult mosquitoes were sampled indoors by pyrethrum spray catch and outdoors by the Centers for Disease Control and Prevention light traps . Mosquitoes were then morphologically identified to species using taxonomic keys . The characteristics of houses sampled for indoor resting mosquitoes , including number of people sleeping in each house the night preceding collection , presence of bed nets , location of the house , size of eaves , wall type , presence of cattle and distance of the house to the cowshed , and proximity to larval habitats , were recorded . Of the 191 , 378 mosquitoes collected , 95% were identified morphologically to species and comprised 25 species from 5 genera . Common species included Anopheles arabiensis ( 53 . 5% ) , Culex quinquefasciatus ( 35 . 5% ) , An . pharoensis ( 4 . 7% ) , An . coustani ( 2 . 5% ) , and An . funestus ( 1 . 6% ) . Shannons species diversity and evenness indices did not differ significantly among the 3 study sites . There was a marked house-to-house variation in the average number of mosquitoes captured . The number of people sleeping in the house the night preceding collection , size of eaves , distance to the cowshed , and the nearest larval habitat were significant predictors of occurrence of either or both An . arabiensis and Cx . quinquefasciatus . The peak abundance of An . arabiensis coincided with land preparation and the first few weeks after transplanting of rice seedlings , and that of Cx . quinquefasciatus coincided with land preparation , late stage of rice development , and short rains .

[ Sen. 4, subscore: 1.00 ]: To test the hypothesis that silicon ( Si ) confers resistance against appressorial penetration of the rice blast fungus , the proportion of appressorial penetration into the leaf epidermis to total appressoria formed was compared among rice plants amended with various rates of silica gel to those plants nonamended . The amounts of Si in the youngest leaves were consistent with the amounts of silica gel applied to the rice plants . Relative Si levels on the adaxial surface of leaves as detected by energy dispersive X-ray analysis also increased with the amounts of silica gel applied . Based on light microscopic observation of the adaxial surface of rice leaves , the proportion of appressorial penetration was reduced by increasing amounts of silica gel applied and increased with the length of period after spray inoculation . Consequently , these results strongly support the hypothesis and suggest that Si in the leaf epidermis may confer resistance against appressorial penetration . Meanwhile , the number of lesions per leaf also decreased with the amount of Si applied , while only a certain part of penetrated appressoria could become sporulating susceptible lesions . This suggests that Si also confers physiological resistance against blast infection after the penetration .

We hypothesized that H ( 2 ) would improve outcomes after neonatal HI by scavenging free radicals . Two hundred ( 200 ) unsexed Sprague-Dawley rats at day 10 of life ( p10 ) underwent neonatal HI with the Rice-Vannucci model . Multiple treatment protocols were studied , including pre-ischemic treatment , intra-ischemic treatment , and post-ischemic treatment ( Sham n=32 , HI n=82 , HI+H ( 2 ) n=86 ) . We also tested H ( 2 ) in middle cerebral artery occlusion ( MCAO ) in adult rats ( MCAO n=9 , MCAO+H ( 2 ) n=7 ) for comparison . Analysis at 24 h included infarction volume , measurement of brain concentration of malondialdehyde ( MDA ) ( an end-product of lipid peroxidation ) , daily weight , Nissl histology , and mortality . In moderate and severe neonatal HI models , hydrogen gas therapy ( 2 . 9% concentration H ( 2 ) ) was not associated with decreased volume of infarction or decreased concentration of MDA . H ( 2 ) gas pretreatment ( 2 . 9% ) was associated with increased infarction volume in neonatal HI . In MCAO in adult rats , H ( 2 ) gas therapy demonstrated a trend of beneficial effect . Exposure of H ( 2 ) gas to non-ischemic neonates resulted in a significant increase in brain concentration of MDA . We conclude that 2 . 9% H ( 2 ) gas therapy does not ameliorate moderate to severe ischemic damage in neonatal hypoxia-ischemia .

[ Sen. 5, subscore: 1.00 ]: ABSTRACT : BACKGROUND : Simple modifications of typical rural house design can be an effective and relatively inexpensive method of reducing indoor mosquito vector densities and consequently decreasing malaria transmission . Public health scientists have shown the potential for house design to protect people against malaria , yet this type of intervention remains virtually ignored . A randomized-controlled study was , therefore , undertaken to determine the effects of this method of vector control on the density of indoor resting malaria vectors in a rice irrigation scheme area in lowlands of western Kenya . METHODS : Ten treatment houses were modified with ceilings of papyrus mats and insecticide-treated netting ( ITN ) and tested against ten control houses without papyrus ceilings . To determine densities of mosquitoes resting in homes , the pyrethrum spray method was used to simultaneously collect indoor resting malaria vectors in intervention and control houses . Each house was sampled a total of eight times over a period of four months , resulting in a total of 80 sampling efforts for each treatment . Community response to such intervention was investigated by discussions with residents . RESULTS : Papyrus mats ceiling modification reduced house entry by Anopheles gambiae s . l and Anopheles funestus densities by between 78-80% and 86% respectively compared to unmodified houses . Geometric mean density of Anopheles gambiae s . l . and Anopheles funestus in modified houses were significantly lower ( t18 = 7 . 174 , P < 0 . 0001 and t18 = 2 . 52 , P = 0 . 02 , respectively ) compared to controls . Unmodified houses were associated with relatively higher densities of malaria vectors . There was a 84% ( OR 0 . 16 , 95% CI 0 . 07-0 . 39 , P < 0 . 0001 ) and 87% ( OR 0 . 13 , 95% CI 0 . 03-0 . 5 , P = 0 . 0004 ) reduction in the odds of Anopheles gambiae s . l . and Anopheles funestus presence in modified houses , respectively , compared with unmodified houses . Residents responded favourably to this mode of vector control . CONCLUSION : House modifications involving insect screen ceilings made from locally available materials and small ITN incorporated in house construction have the potential to reduce human exposure to malaria vectors , and thus parasite infection , in a rice irrigation scheme area of western Kenya . Ceiling modification is likely to be acceptable and is expected to be of greatest benefit when used in combination with other malaria control strategies .

In this study , anopheline species composition and their relation to malaria transmission were investigated in a dry Sudanian savannas area of Chad . METHODS : A 12-month longitudinal survey was conducted in the irrigated rice-fields area of Goulmoun in south western Chad . Human landing catches were performed each month from July 2006 to June 2007 in three compounds ( indoors and outdoors ) and pyrethrum spray collections were conducted in July , August and October 2006 in 10 randomly selected rooms . Mosquitoes belonging to the Anopheles gambiae complex and to the An . funestus group were identified by molecular diagnostic tools . Plasmodium falciparum infection and blood meal sources were detected by ELISA . RESULTS : Nine anopheline species were collected by the two sampling methods . The most aggressive species were An . arabiensis ( 51 bites/human/night ) , An . pharoensis ( 12 . 5 b/h/n ) , An . funestus ( 1 . 5 b/h/n ) and An . ziemanni ( 1 . 3 b/h/n ) .

[ Sen. 2, subscore: 1.00 ]: This study is carried out to determine the potential of phytic acid extracted from rice bran in the suppression of colon carcinogenesis induced by azoxymethane ( AOM ) in rats . Seventy-two male Sprague-Dawley rats were divided into 6 groups with 12 rats in each group . The intended rats for cancer treatment received two intraperitoneal injections of AOM in saline ( 15mg/kg bodyweight ) over a 2-week period . The treatments of phytic acid were given in two concentrations : 0 . 2% ( w/v ) and 0 . 5% ( w/v ) during the post-initiation phase of carcinogenesis phase via drinking water . The colons of the animals were analyzed for detection and quantification of aberrant crypt foci ( ACF ) after 8 weeks of treatment . The finding showed treatment with 0 . 2% ( w/v ) extract phytic acid ( EPA ) gave the greatest reduction in the formation of ACF . In addition , phytic acid significantly suppressed the number of ACF in the distal , middle and proximal colon as compared to AOM alone ( p<0 . 05 ) . For the histological classification of ACF , treatment with 0 . 5% ( w/v ) commercial phytic acid ( CPA ) had the highest percentage ( 71% ) of non-dysplastic ACF followed by treatment with 0 . 2% ( w/v ) EPA ( 61% ) . Administration of phytic acid also reduced the incidence and multiplicity of total tumors even though there were no significant differences between groups . In conclusion , this study found the potential value of phytic acid extracted from rice bran in reducing colon cancer risk in rats .

[ Sen. 6, subscore: 1.00 ]: Molinate has been widely used as a pre emergent herbicide in the rice fields of Californias Central Valley . In rat studies , the metabolite molinate sulfoxide is suspected of causing testicular toxicity after exposure to molinate . The sulfoxide is generated in the liver and can circulate in the blood , eventually reaching the testis . Man qualitatively produces the same molinate metabolites as the rat . To extrapolate the reproductive risk to man , the present study outlines the development of a preliminary PBPK ( Physiologically-based Pharmacokinetic ) model , validation in the rat and extrapolation to man . The preliminary seven-compartment PBPK model for molinate was constructed for the adult , male Sprague-Dawley rat that employed both flow-limited ( blood , kidney , liver , rapid-perfused it issues and slowly perfused it issues ) and diffusion-limited ( fat ) rate equations . The systemic circulation connects the various compartments . The simulations predict the molinate blood concentrations of the rat blood and testes compartment favorably with the profiles obtained from 10 and 100 mg/kg po or 1 . 5 and 15 mg/kg iv doses . Human physiological parameters were substituted into the oral dosed model and the simulations closely predicted the molinate blood concentration obtained from 5 . 06 mg oral dose . A sensitivity analysis determined for an oral dose that peak blood molinate concentrations were most responsive to the blood flows to kidney and fat compartments while testicular molinate sulfoxide concentrations depended on molinate sulfoxide partition coefficients for the testes compartment and the Km for glutathione conjugation of molinate sulfoxide in the liver compartment .

[ Sen. 3, subscore: 1.00 ]: To develop a specific inhibitor of abscisic acid ( ABA ) 8-hydroxylase , a key enzyme in the catabolism of ABA , a plant hormone involved in stress tolerance , seed dormancy , and other various physiological events , we designed and synthesized conformationally restricted analogues of uniconazole ( UNI ) , a well-known plant growth retardant , which inhibits a biosynthetic enzyme ( ent-kaurene oxidase ) of gibberellin as well as ABA 8-hydroxylase . Although most of these analogues were less effective than UNI in inhibition of ABA 8-hydroxylase and rice seedling growth , we found that a lactol-bridged analogue with an imidazole is a potent inhibitor of ABA 8-hydroxylase but not of plant growth . This compound , abscinazole-F1 , induced drought tolerance in apple seedlings upon spray treatment with a 10 microM solution .

[ Sen. 3, subscore: 1.00 ]: The widespread use of insecticides is known to cause resurgence in Nilaparvata lugens ( Stal ) ( Hemiptera : Delphacidae ) populations , a serious insect pest of rice , Orzya sativa L , crops in Asia . The current study investigated insecticide-induced changes in protein , RNA , and DNA levels in the ovary and fat body of adult female N lugens . Potted rice plants were sprayed with different concentrations of imidacloprid , triazophos , and detamethrin . The results showed that all three insecticides caused a significant increase in protein and RNA contents in the ovary and fat body of adult females developed from nymphs fed on treated plants compared with those from on untreated plants , although there was no significant effect on DNA content . In general , protein and RNA contents in both ovary and fat body increased linearly with insecticide concentrations or days after emergence ( DAEs ) when they were applied . There was a significant correlation between protein content and RNA content in both ovary and fat body . In addition , the relationship between ratios of RNA to protein in ovary and fat body of adult female N lugens and insecticide concentrations showed a significant positive correlation for most DAEs of imidacloprid and several DAEs of triazophos and deltamethrin treatments . These findings suggest that RNA in both ovary and fat body was more sensitive to insecticides and that the insecticide-induced changes in RNA content in turn influence protein synthesis in ovary and fat body . Consistently , RNA-to-protein ratios in ovary and fat body were approximately 0 . 42 in all treatments and controls .

METHODS : Seven-day-old Sprague-Dawley rats were randomly divided into the normal control ( CON ) , the HIBD model and the HBO groups ( HBO treatment was administered at 2 ATA , once daily for 7 days within 3 hrs after HIBD ) . HIBD model was prepared according to the classic Rice-Vannucci method . BrdU/DCX , BrdU/beta-tubulin , BrdU/GFAP and BrdU/O4 immunofluorescence were examined by confocal microscopy in the subventricular zone ( SVZ ) and the cortex 7 , 14 and 28 days after HBO treatment . RESULTS : The BrdU ( + ) DCX ( + ) cells in the SVZ ( 84 +/- 21 cells/mm2 ) in the HBO group were significantly higher than those in the CON group ( 39 +/- 14 cells/mm2 ) ( p<0 . 05 ) and the HIBD model group ( 68 +/- 17 cells/mm2 ) ( p<0 . 05 ) 7 days after HBO treatment . Fourteen days after HBO treatment , the BrdU ( + ) DCX ( + ) cells decreased in the SVZ and more cells were observed in the cortex in the HBO group as compared with the CON group ( p<0 . 01 ) . The BrdU ( + ) beta-tubulin ( + ) , BrdU ( + ) GFAP ( + ) and BrdU ( + ) O4 ( + ) cells were observed in the cortex , and more BrdU ( + ) beta-tubulin ( + ) and BrdU ( + ) O4 ( + ) cells were observed in the HBO group as compared with the CON and the HIBD model groups ( p<0 . 05 ) 28 days after HBO treatment .

Ca ( 2+ ) -mediated signal transduction is involved in key pathways that contribute to a variety of fundamental physiological processes in eukaryotic cells . However , little is known about the molecular mechanisms of Ca ( 2+ ) -mediated signal transduction in filamentous fungi . In this study , the MoCMK1 gene , encoding a putative Ca ( 2+ ) /calmodulin-dependent kinase , was identified in the rice blast fungus Magnaporthe oryzae . Three MoCMK1 deletion mutants were obtained by a targeted gene replacement . Colonies of the MoCMK1 mutants had sparse aerial hyphae and fewer conidia than the wild-type strain on complete medium . Conidial germination and appressorial formation were delayed in the DeltaMocmk1 mutants . In spray inoculation tests , DeltaMocmk1 mutants exhibited a weakened ability to infect the susceptible rice cultivar CO-39 , compared to the wild-type strain Guy11 . These results showed that MoCMK1 plays key roles in the pathogenicity of the rice blast fungus .

To evaluate the preventive effects on hangover , rats were orally administered GEY/RES ( 50/2 . 5 , 100/5 , or 200/10 mg/kg ) for 2 weeks . At 30 minutes after the final treatment , they were challenged with 3 mL/kg ethanol ( 15 mL of 20% in water/kg ) . The blood concentrations of alcohol and acetaldehyde were analyzed up to 7 hours postchallenge . Hepatic mRNA expression levels of alcohol-metabolizing enzymes , alcohol dehydrogenase ( ADH ) , cytochrome P450 type 2E1 ( CYP2E1 ) , and aldehyde dehydrogenase ( ALDH ) , were determined by real-time polymerase chain reaction . Additional rats were challenged with ethanol and , 60 minutes later , administered GEY/RES to evaluate alcohol clearance . Pretreatment with GEY/RES for 2 weeks reduced the blood concentrations of alcohol and acetaldehyde in a dose-dependent manner , lowering by 29 . 5% and 54 . 6% at the highest dose ( 200/10 mg/kg ) , respectively . The expressions of mRNAs for ADH and ALDH , the major alcohol-metabolizing enzymes , were markedly increased in the livers of rats administered GEY/RES for 2 weeks , whereas CYP2E1 mRNA was suppressed . Postchallenge treatment with GEY/RES enhanced the alcohol clearance rate by lowering blood concentrations of alcohol and acetaldehyde by 24% and 26 . 6% , respectively , for the highest dose group . GEY/RES remarkably eliminated 2 , 2-diphenyl-1-picrylhydrazyl hydrate radical and FeCl ( 3 ) -mediated lipid peroxidation in vitro and attenuated hepatic lipid accumulation following ethanol administration in vivo .

[ Sen. 1, subscore: 1.00 ]: INTRODUCTION : Malaria control measures such as early diagnosis and treatment , intermittent treatment of pregnant women , impregnated bed nets , indoor spraying and larval control measures are difficult to target specifically because of imprecise estimates of risk at a small-scale level . Ways of estimating local risks for malaria are therefore important . METHODS : A high-resolution satellite view from the SPOT 5 satellite during 2008 was used to generate a land cover classification in the malaria endemic lowland of North-Western Burkina Faso . For the area of a complete satellite view of 60 x 60 km , a supervised land cover classification was carried out . Ten classes were built and correlated to land cover types known for acting as Anopheles mosquito breeding sites . RESULTS : According to known correlations of Anopheles larvae presence and surface water-related land cover , cultivated areas in the riverine vicinity of Kossi River were shown to be one of the most favourable sites for Anopheles production . Similar conditions prevail in the South of the study region , where clayey soils and higher precipitations benefit the occurrence of surface water . Besides pools , which are often directly detectable , rice fields and occasionally flooded crops represent most appropriate habitats . On the other hand , forests , elevated regions on porous soils , grasslands and the dryer , sandy soils in the north-western part turned out to deliver fewer mosquito breeding opportunities . CONCLUSIONS : Potential high and low risks for malaria at the village level can be differentiated from satellite data .

The surface morphology changed from an irregular to concave spherical shape as revealed by Scanning Electron Microscopy ( SEM ) . SGRS was almost amorphous as determined by X-ray Diffraction ( XRD ) spectroscopy . The water molecules became linked through hydrogen bonds to the exposed hydroxyl group of amorphous SGRS as determined by Near Infrared ( NIR ) spectroscopy . Then , SGRS formed a colloid gel matrix with water and developed a highly viscous gelatinous form as determined using Differential Scanning Calorimetry ( DSC ) and a stress control type rheometer . In addition , SGRS can swell and produce a gelatinous surface barrier like a hydrophilic matrix biopolymer which controls drug release . Therefore , a novel application of SGRS is as a sustained release modifier for direct compression tablets in the pharmaceutical industry .

GBR is brown rice that has been claimed to be richer in nutrients compared to the common white rice . The male Sprague Dawley rats ( 6 weeks of age ) were randomly divided into 5 groups : ( G1 ) positive control ( with colon cancer , unfed with GBR ) , ( G2 ) fed with 2 . 5 g/kg of GBR ( GBR ( g ) /weight of rat ( kg ) ) , ( G3 ) fed with 5 g/kg of GBR , ( G4 ) fed with 10 g/kg of GBR and ( G5 ) negative control ( without colon cancer , unfed with GBR ) . GBR was administered orally once daily via gavage after injection of 15 mg/kg of body weight of azoxymethane ( AOM ) once a week for two weeks , intraperitonially . After 8 weeks of treatment , animals were sacrificed and colons were removed . Colonic aberrant crypt foci ( ACF ) were evaluated histopathologically . Total number of ACF and AC , and multicrypt of ACF , and the expression of beta-catenin and COX-2 reduced significantly ( p < 0 . 05 ) in all the groups treated with GBR ( G2 , G3 and G4 ) compared to the control group ( G1 ) . Spearman rank correlation test showed significant positive linear relationship between total beta-catenin and COX-2 score ( Spearmans rho = 0 . 616 , p = 0 . 0001 ) . It is demonstrated that GBR inhibits the development of total number of ACF and AC , and multicrypt of ACF , reduces the expression of beta-catenin and COX-2 , and thus can be a promising dietary supplement in prevention of colon cancer .

Transgenic rice has been used as a bioreactor for mass production of recombinant hLF . However , one major concern over such transgenic rice is the risk of its unintended spreading into environment and into our food supplies . Here we report the development of selectively terminable transgenic rice expressing human lactoferrin in seeds . These transgenic rice plants could be selectively terminated by bentazon , a common herbicide used for rice weed control . The hLF expression cassette was constructed into a T-DNA containing the RNA interference cassette suppressing the expression of the rice gene CYP81A6 which detoxifies herbicide bentazon , and the 5-enolpyruvylshikimate-3-phosphate synthase ( EPSPS ) cassette which confers to glyphosate tolerance . A transgenic line , named as G281 , was identified for its high sensitivity to bentazon , high tolerance to glyphosate , and high expression of hLF . Southern analysis suggested G281 is a single copy insertion event . Field tests demonstrated that G281 plants can be completely killed by a single spray of bentazon at 1000 mg/L , which is safe to regular rice and represents only half of the dose recommended by manufacturer for rice field weed control . Therefore , any G281 contaminations in regular rice could be selectively terminated to make sure it will not enter food or feed supplies .

Peroxisome proliferator-activated receptor ( PPAR ) alpha genes and proteins involved in fatty acid degradation were upregulated by feeding RPI ( P < 0 . 05 ) , accompanied by increased promoter binding and nuclear expression of PPARalpha and its heterodimerization partner retinoid X receptor ( P < 0 . 05 ) . Effects of RPI feeding on hepatic PPARgamma signaling were significant but less robust Feeding RPI also increased hepatic genes involved in cholesterol metabolism and transport . However , feeding RPI had no effect on binding of liver X-receptor ( LXR ) alpha to the cytochrome P450 ( CYP ) 7A1 promoter . The effect of RPI feeding on PPARalpha signaling appeared to be direct and was reversed when RPI diets were switched to casein . In another experiment , male Sprague-Dawley rats were fed casein diets from postnatal day ( PND ) 24 to PND64 or were fed high fat Western diets containing 0 . 5% cholesterol made with either casein or RPI . Increased liver triglyceride content , hypercholesterolemia and insulin resistance in the Western diet-fed rats were partially prevented by feeding RPI ( P < 0 . 05 ) . mRNA and protein expression of hepatic enzymes involved in fatty acid synthesis were suppressed by feeding Western diets containing RPI ( P < 0 . 05 ) , despite a lack of effects on nuclear concentrations of sterol regulatory element binding protein-1c . These data suggest that attenuation of metabolic syndrome observed in RPI-fed rats after consumption of diets high in fat and cholesterol occur as a result of improved lipid and glucose homeostasis partly as a result of activation of PPARs .

[ Sen. 4, subscore: 1.00 ]: BACKGROUND : Enzyme-treated rice fiber ( ERF ) is a recently developed prebiotic product made from rice bran by heat-resistant amylase , protease and hemicellulase treatment . Although the detailed mechanism of inflammatory bowel disease ( IBD ) is still unclear , the role of the resident luminal bacteria and its interaction on the mucosal barrier seem to be an important factor in the development of IBD and its chronicity . With the objective of manipulating the intestinal microbiota in IBD , this study was carried out to evaluate the effects of ERF on IBD with using experimental colitis models . METHODS : Three colitis models were used and they were induced by the oral administration of dextran sodium sulfate in male Sprague-Dawley rats or BALB/c mice and transferring CD4+ CD45RB ( high ) T cells to female SCID mice , sequentially their CD4+ T cells were retransferred to new SCID mice . The evaluation included the measurement of body weight , spleen weight , colon length , histological examination , serum and mucosal cytokine ( tumor necrosis factor-alpha ( TNF-alpha ) , an interferon-gamma ( IFN-gamma ) , interleukin-12 p70 ( IL-12p70 ) , IL-1beta , IL-6 , IL-4 ) analysis , mucosal serotonin ( 5HT ) , and organic acid production and a microbiota analysis of the cecal contents . The characteristics of T cell surface markers including CD4 , CD69 , CD45RB of spleen and mesenteric lymph nodes ( MLN ) were also analyzed . In addition , the effects of ERF on the change in the induction of dendritic cells ( DCs ) were evaluated . RESULTS : The preventive effect of ERF on colitis was significantly superior to that of raw material rice bran or control group . An overexpression of inflammatory cytokine production was attenuated by ERF treatment , which was accompanied with a decrease in both the colonic mucosal damage and 5HT production . Furthermore , ERF significantly attenuated the T cell activation ( CD4+CD69+ ) of spleen and MLN , and this characteristic was inherited by the retransferred mice . ERF significantly suppressed the growth of Clostiridium , and increased short-chain fatty acids ( acetate , propionate and butyrate ) content in colitis . The relatively hydrophilic fraction of ERF ( ethanol-methanol soluble fraction ) is therefore considered to have a potent ability to attenuate the induction of DCs . CONCLUSION : A new prebiotic , ERF , reduced inflammation by modulating the colonic environment and regulating immune cell differentiation .

[ Sen. 3, subscore: 1.00 ]: Chlorfenapyr is a pyrrole insecticide with a unique non-neurological mode of action . Laboratory bioassays of chlorfenapyr comparing the mortality of pyrethroid-susceptible and -resistant Anopheles gambiae s . s . and Culex quinquefasciatus mosquitoes indicated that operational cross-resistance is unlikely to occur ( resistance ratio ranged between 0 and 2 . 1 ) . Three trials of chlorfenapyr indoor residual spraying were undertaken in experimental huts in an area of rice irrigation in northern Tanzania that supports breeding of A arabiensis . Daily mosquito collections were undertaken to assess product performance primarily in terms of mortality . In the second trial , 250mg/m ( 2 ) and 500mg/m ( 2 ) chlorfenapyr were tested for residual efficacy over 6 months . Both dosages killed 54% of C quinquefasciatus , whilst for A arabiensis 250mg/m ( 2 ) killed 48% compared with 41% for 500mg/m ( 2 ) ; mortality was as high at the end of the trial as at the beginning . In the third trial , 250mg/m ( 2 ) chlorfenapyr was compared with the pyrethroid alpha-cypermethrin dosed at 30mg/m ( 2 ) . Chlorfenapyr performance was equivalent to the pyrethroid against A arabiensis , with both insecticides killing 50% of mosquitoes . Chlorfenapyr killed a significantly higher proportion of pyrethroid-resistant C quinquefasciatus ( 56% ) compared with alpha-cypermethrin ( 17% ) . Chlorfenapyr has the potential to be an important addition to the limited arsenal of public health insecticides for indoor residual control of A arabiensis and pyrethroid-resistant species of mosquito .

[ Sen. 3, subscore: 1.00 ]: BACKGROUND : Based on recent studies in Israel demonstrating that attractive toxic sugar bait ( ATSB ) methods can be used to decimate local anopheline and culicine mosquito populations , an important consideration is whether the same methods can be adapted and improved to attract and kill malaria vectors in Africa . The ATSB approach uses fruit or flower scent as an attractant , sugar solution as a feeding stimulant , and an oral toxin . The ATSB solutions are either sprayed on vegetation or suspended in simple bait stations , and the mosquitoes ingesting the toxic solutions are killed . As such , this approach targets sugar-feeding female and male mosquitoes . This study examines the attractiveness of African malaria vectors to local fruits/seedpods and flowering plants , key biological elements of the ATSB approach for mosquito control . METHODS : Three field experiments were conducted at sites in Mali . The attraction of Anopheles gambiae s . l . to 26 different local fruits and seedpods was determined at a site in the semi-arid Bandiagara District of Mali . Wire mesh glue traps with fruits/seedpods suspended on skewers inside were set along a seasonal lagoon . Seven replicates of each fruit/seedpod species were tested , with a water-soaked sponge and a sugar-soaked sponge as controls . The attraction of An . gambiae s . l . to 26 different types of flowering plants was determined at a site near Mopti in Mali . The flowering plants held in a water-filled buried container were tested using the same glue traps , with controls including water only and sugar solution . Six replicates of each selected plant type were tested on transects between rice paddies .

[ Sen. 3, subscore: 1.00 ]: Drugs that selectively inhibit the serotonin transporter ( SERT ) are widely prescribed for treatment of depression and a range of anxiety disorders . We studied the time course of changes in tryptophan hydroxylase ( TPH ) in four raphe nuclei after initiation of two different SERT inhibitors , citalopram and fluoxetine . In the first experiment , groups of Sprague-Dawley rats received daily meals of rice pudding either alone ( n=9 ) or mixed with citalopram 5 mg/kg/day ( n=27 ) . Rats were sacrificed after 24 h , 7 days or 28 days of treatment . Sections of dorsal raphe nucleus ( DRN ) , median raphe nucleus ( MRN ) , raphe magnus nucleus ( RMN ) and caudal linear nucleus ( CLN ) were processed for TPH immunohistochemistry . Citalopram induced a significant reduction in DRN TPH-positive cell counts at 24 h ( 41% ) , 7 days ( 38% ) and 28 days ( 52% ) . Similar reductions in TPH-positive cell counts were also observed at each timepoint in the MRN and in the RMN . In the MRN , citalopram resulted in significant reductions at 24 h ( 26% ) , 7 days ( 16% ) and 28 days ( 23% ) . In the RMN , citalopram induced significant reductions of TPH-positive cell counts at 24 h ( 45% ) , 7 days ( 34% ) and 28 days ( 43% ) . By contrast , no significant differences between control and treatment groups were observed in the CLN at any of the time points that we studied . To investigate whether these changes would occur with other SERT inhibitors , we conducted a second experiment , this time with a 28-day course of fluoxetine . As was observed with citalopram , fluoxetine induced significant reductions of TPH cell counts in the DRN ( 39% ) , MRN ( 38% ) and RMN ( 41% ) , with no significant differences in the CLN .

[ Sen. 2, subscore: 1.00 ]: In entomopathogenic hyphomycetes , desired candidates against the brown planthopper , Nilaparvata lugens ( a sap-sucking rice pest in Asia ) , are lacking . In this study , 21 Beauveria bassiana isolates from heterologous host insects showed low pathogenicity to third-instar nymphs sprayed at the high concentration of approximately 1000 conidia/mm ( 2 ) , causing only 2-23% mortalities . Of those , three isolates killed significantly more nymphs ( up to 45-62% ) after two in vivo passages but no more after further passage . Conidial hydrophobicity rates ( H ( r ) ) , zeta potentials ( P ( z ) ) , and subtilisin-like protease ( Pr1 ) activities ( A ( p ) ) of these isolates showed the same trends in the three host passages ( N : 0-3 ) . In multivariate correlation , the variables N , H ( r ) and P ( z ) were found contributing 89% to the mortality variation ( r ( 2 ) =0 . 89 ) . Significant positive correlations were also found between H ( r ) and N ( r ( 2 ) =0 . 64 ) , P ( z ) and N ( r ( 2 ) =0 . 52 ) , A ( p ) and N ( r ( 2 ) =0 . 51 ) , H ( r ) and A ( p ) ( r ( 2 ) =0 . 45 ) , and P ( z ) and A ( p ) ( r ( 2 ) =0 . 57 ) , respectively . However , irregular changes of H ( r ) and P ( z ) occurred in four other isolates , whose pathogenicity to N lugens was not enhanced by repeated host passages , resulting in no correlation between the variables . Our data indicate that the conidial surface properties H ( r ) and P ( z ) associated with cuticle adhesion reflect the heterologous host-induced adaptation and help to select fungal candidates against N lugens from repeated in vivo passages .

[ Sen. 5, subscore: 1.00 ]: Although resveratrol has been proven to possess diverse health benefits , several recent reports have demonstrated conflicting results on some aspects of its effects , including its anti-aging properties . Considerable debate appears to exist on the dose and bioavailability of resveratrol , leading to the controversies on its effectiveness . To resolve the problem , we designed a study with a resveratrol formulation that contained resveratrol supplemented with 5% quercetin and 5% rice bran phytate ( commercially known as Longevinex ) . These ingredients were micronized to increase the bioavailability . Sprague-Dawley rats were gavaged with either Longevinex or vehicle ( 5% quercetin plus 5% rice bran phytate ) , and rats were sacrificed after 1 or 3 months , when isolated working hearts were subjected to 30 min ischemia followed by 2 h of reperfusion . Longevinex-treated hearts , irrespective of the duration of treatments , revealed superior cardiac performance , reduced infarct size , and induction of survival signals as evidenced by increased Bcl2/Bax ratio and enhanced Akt phosphorylation . In contrast , LC3-II and Beclin were enhanced significantly after 3 months of Longevinex treatment , suggesting that autophagy occurred only after feeding Longevinex to rats for a prolonged period of time . Corroborating with the results of autophagy , Sirt1 and Sirt3 increased significantly only after 3 months of Longevinex treatment , suggesting that enhanced expression of Sirts correlated with induction of autophagy . In concert , Longevinex caused phosphorylation and nuclear translocation of FoxO1 , FoxO3a , and FoxO4 , indicating involvement of FoxOs with autophagy . Since Sirts and FoxOs are reliable markers of longevity , the results appear to suggest that Longevinex induces longevity after prolonged feeding via induction of autophagy , while it converts death signals into survival signals and provides cardioprotection within a relatively shorter period of time .

The ability of pyridine-2-aldoxime methochloride ( 2-PAM ) to reactivate BChE levels was also explored . In addition , changes in blood cell morphology and parasite infection were determined . Mean values of plasma BChE activities were lower in samples from the two rice fields than in those from the reference site . CbE ( 4-nitrophenyl valerate ) levels varied in the three sites studied , being highest in RF1 . Frog plasma from RF1 showed positive reactivation of BChE activity after incubation with 2-PAM . Blood parameters of frogs from RF2 revealed morphological alterations ( anisochromasia and immature erythrocytes frequency ) . Moreover , a major infection of protozoan Trypanosoma sp . in individuals from the two rice fields was detected . We suggest that integrated use of several biomarkers ( BChE and CBEs , chemical reactivation of plasma with 2-PAM , and blood cell parameters ) may be a promising procedure for use in biomonitoring programmes to diagnose pesticide exposure of wild populations of this frog and other native anuran species in Argentina .

METHODS : Ninety neonatal Sprague-Dawley rats were randomly divided into three groups : normal control , HIBD , and HIBD+rhIGF-1 ( rhIGF-1 was given intraperitoneally right after HI ) . Rat HIBD model was prepared according the Rice-Vannucci method . RT-PCR and Western blot methods were used to measure the mRNA and protein expression of Cyt-C and caspase-3 24 , 48 and 72 hrs after HI ( n=10 each time point ) . RESULTS : At all time points , both Cyt-C mRNA and caspase-3 mRNA expression levels in the HIBD group increased compared with those in the normal control group , and those in the HIBD+rhIGF-1 group also increased compared with that in the normal control group but decreased compared with that in the HIBD group . There were statistical significances among the three groups ( P<0 . 01 ) . At all time points , the changes of both Cyt-C and caspase-3 protein expression in the three groups were similar to those of the mRNA expression : both Cyt-C and caspase-3 protein expression levels increased in the HIBD group compared with those in the normal control group , and those in the HIBD+rhIGF-1 group also increased compared with those in the normal control group but decreased compared with those in the HIBD group . There were statistical significances among the three groups ( P<0 . 01 ) . Pearson correlation analysis showed that mRNA and protein expression of Cyt-C were positively correlated to casapse-3 mRNA and protein expression in the HIBD and the HIBD+rhIGF-1 groups . CONCLUSIONS : rhIGF-1 may inhibit the Cyt-C release and caspase-3 expression , and thus provides neuroprotection against HIBD in neonatal rats .

The HIBD model of neonatal rats was prepared by the Rice-Vennucci method . Electric stimulation at the cerebellar fastigial nucleus was given 24 hrs after the operation in the electric stimulation group once daily and lasted for 30 minutes each time . The other two groups were not subjected to electric stimulation but captured to fix in corresponding periods . Rats were sacrificed 3 , 7 , 14 and 21 days after stimulations to observe the glial fibrillary acidic protein ( GFAP ) expression by immunohistochemisty and the ultrastructural changes of astrocytes in the hippocampus under an electron microscope . RESULTS : Immunohistochemical analysis showed the expression of GFAP in the HIBD groups with and without electric stimulation increased significantly compared with the control group on day 3 , reached the peak on day 7 , and the increased expression remained till to day 21 . The GFAP expression in the electric stimulation group was significantly lower than that in the untreated HIBD group at all time points . Under the electron microscope , the astrocytes in the untreated HIBD group were swollen and the amount of organelles was reduced , while the swelling of astrocytes was alleviated and the organelles remained in integrity in the electric stimulation group . CONCLUSIONS : The electric stimulation at the cerebellar fastigial nucleus can inhibit the excessive proliferation of astrocytes and relieve the structural damage of astrocytes in neonatal rats following HIBD .

The mixture of fipronil , applied in the rice nursery box , and its desulfinyl , sulfide , and sulfone TPs were detected in the river for several months after transplanting , and they were more toxic to C brevilineata than the other tested compounds . The toxicities of the parent compound and its TPs , such as fipronil and its TPs , may be related to their hydrophobicities . Risk quotients for mixtures ( RQ ( mix ) ) of only parent compounds did not exceed 1 , but , in mid-June 2009 , the RQ ( mix ) of parent compounds and TPs for caddisflies exceeded 1 . Diazinon , fenitrothion , and fenthion sprayed on the rice crop and their TPs posed a sporadic risk for cladocerans , depending on the application timing , whereas fipronil TPs contributed to the RQ ( mix ) for caddisflies for several months after transplanting . The risk of mixtures of insecticides and their TPs differed seasonally between caddisflies and cladocerans , depending on insecticide application timing and the persistence and toxicity of TPs .

These agents are associated with a range of extrapyramidal syndromes such as akathisia , dystonia , dyskinesia and parkinsonism , suggesting an effect on dopaminergic transmission . We studied the time course of changes in dopaminergic neurons in the substantia nigra ( SN ) after initiation of two different SERT inhibitors , citalopram and fluoxetine . In the first experiment , groups of Sprague-Dawley rats received daily meals of rice pudding either alone ( N = 9 ) or mixed with citalopram 5 mg/kg/day ( N = 27 ) . Rats were sacrificed after 24 h , 7 days or 28 days of treatment . Sections of SN were processed for tyrosine hydroxylase ( TH ) immunohistochemistry . Citalopram induced a significant decrease in TH-positive cell counts at 24 h ( 44% ) , 7 days ( 38% ) and 28 days ( 33% ) . No significant differences among the citalopram treatment groups were observed in the SN . To determine whether these changes would occur with other SERT inhibitors , we conducted a second experiment , this time with a 28 day course of fluoxetine . As was observed with citalopram , fluoxetine induced a significant 21% reduction of TH cell counts in the SN . Immunoblot analysis showed that fluoxetine also induced a 45% reduction of striatal TH . To investigate a possible role for the innate immune system in mediating these changes , we also studied the microglial marker OX42 after administration of fluoxetine and noted a significant 63% increase in the SN of fluoxtine-treated animals . These results indicate that SERT inhibition can activate microglia and alter the regulation of TH , the rate limiting enzyme for dopamine biosynthesis .

Litter pH , total VFAs , and NH ( 3 ) fluxes were all lowered ( P< 0 . 05 ) by all of the liquid AlCl ( 3 ) treatments compared with controls during certain times of the 5 week study . However , there were no significant differences among treatments on litter pH at the end of the study ( from 3 to 5 weeks ) or NH ( 3 ) fluxes at beginning of the study ( 0 to 3 weeks ) . Total VFAs were reduced 16 % , 29 % , and 53 % by 100 g liquid AlCl ( 3 ) /kg rice hulls , 200 g liquid AlCl ( 3 ) /kg rice hulls , and 300 g liquid AlCl ( 3 ) /kg rice hulls , respectively . Liquid AlCl ( 3 ) additions reduced NH ( 3 ) fluxes by 35 % , 57 % and 67 % , respectively , at the low , medium and high rates . In summary , these results indicate that adding liquid aluminum chloride to rice hulls would be a useful tool in reducing the negative environmental impact of poultry litter . It should be noted that the decreased VFA production and NH ( 3 ) volatilization was chiefly associated with reduction in litter pH .

[ Sen. 2, subscore: 1.00 ]: To identify genes involved in the response to the fire blight pathogen Erwinia amylovora in apple ( Malusxdomestica ) , expression profiles were investigated using an apple oligo ( 70-mer ) array representing 40 , 000 genes . Blossoms of a fire blight-susceptible apple cultivar Gala were collected from trees growing in the orchard , placed on a tray in the laboratory , and spray-inoculated with a suspension of E amylovora at a concentration of 10 ( 8 ) cfu ml ( -1 ) . Uninoculated detached flowers served as controls at each time point . Expression profiles were captured at three different time points post-inoculation at 2 , 8 , and 24 h , together with those at 0 h ( uninoculated ) . A total of about 3500 genes were found to be significantly modulated in response to at least one of the three time points . Among those , a total of 770 , 855 , and 1002 genes were up-regulated , by 2-fold , at 2 , 8 , and 24 h following inoculation , respectively ; while , 748 , 1024 , and 1455 genes were down-regulated , by 2-fold , at 2 , 8 , and 24 h following inoculation , respectively . Over the three time points post-inoculation , 365 genes were commonly up-regulated and 374 genes were commonly down-regulated . Both sets of genes were classified based on their functional categories . The majority of up-regulated genes were involved in metabolism , signal transduction , signalling , transport , and stress response . A number of transcripts encoding proteins/enzymes known to be up-regulated under particular biotic and abiotic stress were also up-regulated following E amylovora treatment . Those up or down-regulated genes encode transcription factors , signaling components , defense-related , transporter , and metabolism , all of which have been associated with disease responses in Arabidopsis and rice , suggesting similar response pathways are involved in apple blossoms .

[ Sen. 5, subscore: 1.00 ]: Cerebral hypoxia-ischemia ( HI ) is an important cause of mortality and disability in newborns . It is a result of insufficient oxygen and glucose circulation to the brain , initiating long-term cerebral damage and cell death . Emerging evidence suggests that endothelin receptor-A ( ETA ) activation can play an important role in mediating brain damage . In this study , we investigated the role of ETA receptor inhibition using ABT-627 in neonatal HI injured rats . Postnatal day 10 Sprague-Dawley rat pups ( n=91 ) were assigned to the following groups : sham ( n=28 ) , HI ( vehicle , n=32 ) , and HI with ABT-627 at 3 mg/kg ( n=31 ) . The Rice-Vannucci model was used to induce ischemia by ligating the right common carotid artery , followed by a 2 h hypoxic episode using 8% oxygen in a 37 degrees C chamber . Postoperative assessment was conducted at 48 h after injury and again at 4 weeks . At the acute time point , investigative markers included cerebral edema , infarction volume , and body weight change . Neurobehavioral testing was measured at 4 weeks post-injury . Our findings indicated that ABT-627 had no effect on the measured parameters . This study suggests that ETA receptor blockade using ABT-627 post-treatment fails to improve neurological outcomes in neonatal HI injured rats .

[ Sen. 5, subscore: 1.00 ]: Open field , variability of climatic and working conditions , and the use of complex mixtures of pesticides makes biological and environmental monitoring in agriculture , and therefore risk assessment and management , very complicated . A need of pointing out alternative risk assessment approaches , not necessarily based on measures , but simple , user-friendly and reliable , feasible also in the less advanced situations and in particular in small size enterprises , arises . This aim can be reached through a combination of environmental monitoring , biological monitoring and computational modelling . We have used this combination of methods for the creation of "exposure and risk profiles" to be applied in specific exposure scenarios , and we have tested this approach on a sample of Italian rice and maize herbicide applicators . We have given specific "toxicity scores" to the different products used and we have identified , for each of the major working phases , that is mixing and loading , spraying , maintenance and cleaning of equipment , the main variables affecting exposure and inserted them into a simple algorithm , able to produce "exposure indices" . Based on the combination of toxicity indices and exposure indices it is possible to obtain semiquantitative estimates of the risk levels experienced by the workers in the exposure scenarios considered . Results of operator exposure data collected under real-life conditions can be used to validate and refine the algorithms ; moreover , the AOEL derived from pre-marketing studies can be combined to estimate tentative biological exposure limits for pesticides , useful to perform individual risk assessment based on technical surveys and on simple biological monitoring . A proof of principle example of this approach is the subject of this article .

Compositional analysis of TRS demonstrated that the content of resistant starch ( RS ) was significantly higher compared to conventional non-transgenic rice . High level of RS is an important raw material in food industry and has various physiological effects for human health . In order to provide the reliable theory basis for field release of TRS rice , we evaluated the potential health effects of long-term consumption of the TRS . The 90-day toxicology feeding experiment was conducted in Sprague-Dawley rats fed with diets containing 70% of either TRS rice flour , its near-isogenic rice flour or the control diet . The clinical performance variables ( body weight , body weight gain and food consumption ) were measured and pathological responses ( hematological parameters and serum chemistry at the midterm and the completion of the experiment , urinalysis profile and serum sex hormone response at the completion of the experiment ) were performed . Besides , clinical signs , relative organ weights and microscopic observations were also compared between TRS group and its near-isogenic rice group . The combined data indicates that high-amylose TRS grain is as safe as the conventional non-transgenic rice for rat consumption .

However , chlorpyrifos exposure to and adverse effects on farmers has not been evaluated . In this study , biological monitoring of chlorpyrifos exposure in a group of rice farmers was conducted after a typical application event using back-pack spraying . Urine samples ( 24 h ) were collected from the rice farmers before and post insecticide application . Samples were analysed for 3 , 5 , 6-trichloropyridinol ( TCP ) , the major urinary metabolite of chlorpyrifos , using an enzymatic pre-treatment before extraction followed by HPLC-MS/MS . Absorbed Daily Dose ( ADD ) of chlorpyrifos for farmers were then estimated from urinary TCP levels , expressed as mug g ( -1 ) creatinine . The analytical method for urinary TCP had a low detection limit ( 0 . 6 mug L ( -1 ) ) , acceptable recovery values ( 80-114% ) , and low relative percentage differences in duplicate and repeated samples . Post-application chlorpyrifos ADD of farmers varied from 0 . 4 to 94 . 2 mug kg ( -1 ) ( body weight ) d ( -1 ) with a mean of 19 . 4 mug kg ( -1 ) d ( -1 ) which was approximately 80-fold higher than the mean baseline exposure level ( 0 . 24 mug kg ( -1 ) d ( -1 ) ) . Hazard Quotients ( ratio of the mean ADD for rice farmers to acute oral reference dose ) calculated using acute oral reference doses recommended by United States and Australian agencies varied from 2 . 1 ( Australian NRA ) , 4 . 2 ( US EPA ) to 6 . 9 ( ATSDR ) . Biological monitoring using HPLC-MS/MS analysis of urinary TCP ( 24 h ) was found to be an effective method for measuring chlorpyrifos exposure among farmers . This case study found that Vietnamese rice farmers had relatively high exposures to chlorpyrifos after application , which were likely to have adverse health effects .

Although there was a group preference for the Oreo-paired compartment , at the individual level some rats ( 69% ) displayed a preference and others did not . In cocaine SA , preference rats achieved higher break points on a progressive ratio , and displayed greater responding during extinction and cocaine-induced reinstatement . Within the context of this study , Oreo-cocaine cross-reinstatement was not observed . In a control study , rats ( n = 29 ) conditioned with a less palatable food ( rice cakes ) also displayed individual differences in place preference , but not on subsequent cocaine tests . These findings indicate that there is a relationship between incentive learning promoted by palatable foods and by cocaine . This supports the hypothesis that co-morbid food-drug addictions may result from a shared vulnerability to acquire behaviors motivated by strong incentives .

[ Sen. 6, subscore: 1.00 ]: BACKGROUND : The major challenge of cultivating genetically modified ( GM ) rice ( Oryza sativa ) at the commercial scale is to prevent the spread of transgenes from GM cultivated rice to its coexisting weedy rice ( O sativa f . spontanea ) . The strategic development of GM rice with a built-in control mechanism can mitigate transgene spread in weedy rice populations . METHODOLOGY/PRINCIPAL FINDINGS : An RNAi cassette suppressing the expression of the bentazon detoxifying enzyme CYP81A6 was constructed into the T-DNA which contained two tightly linked transgenes expressing the Bt insecticidal protein Cry1Ab and the glyphosate tolerant 5-enolpyruvylshikimate-3-phosphate synthase ( EPSPS ) , respectively . GM rice plants developed from this T-DNA were resistant to lepidopteran pests and tolerant to glyphosate , but sensitive to bentazon . The application of bentazon of 2000 mg/L at the rate of 40 mL/m ( 2 ) , which is approximately the recommended dose for the field application to control common rice weeds , killed all F ( 2 ) plants containing the transgenes generated from the Crop-weed hybrids between a GM rice line ( CGH-13 ) and two weedy rice strains ( PI-63 and PI-1401 ) . CONCLUSIONS/SIGNIFICANCE : Weedy rice plants containing transgenes from GM rice through gene flow can be selectively killed by the spray of bentazon when a non-GM rice variety is cultivated alternately in a few-year interval The built-in control mechanism in combination of cropping management is likely to mitigate the spread of transgenes into weedy rice populations .

F proliferatum is closely related to Gibberella fujikuroi ( anamorph F fujikuroi ) responsible for Bakanae disease in rice ; however there are few reports of F proliferatum as a rice pathogen . In this study , we examined the pathogenic potential of F proliferatum in rice plants with respect to browning , fumonisin production , and survival rates in rice grains . Fungal inoculation was conducted by spraying a conidial suspension of F proliferatum onto rice plants during the flowering period . Browning was found on the stalk , leaf , and ear of rice . Fumonisin B ( 1 ) was detected at levels from trace to 21 ng/g grains , using tandem mass spectrometry . Fungal recovery after 6 months indicated that F proliferatum had high affinity to rice plants being still viable in grains . From this study , it can be concluded that F proliferatum is a possible pathogen of rice and possesses a potential to produce fumonisin B ( 1 ) in rice grains in the field .

Loss of heterozygosity analysis of the Tk mutants revealed that treatments with uncoated Ag-NPs induced mainly chromosomal alterations spanning less than 34 megabase pairs on chromosome 11 . Although no significant induction of DNA damage in Ag-NP-treated mouse lymphoma cells was observed in the standard Comet assay , the Ag-NP treatments induced a dose-responsive increase in oxidative DNA damage in the enzyme-modified Comet assay in which oxidative lesion-specific endonucleases were added . Gene expression analysis using an oxidative stress and antioxidant defense polymerase chain reaction ( PCR ) array showed that the expressions of 17 of the 59 genes on the arrays were altered in the cells treated with Ag-NPs . These genes are involved in production of reactive oxygen species , oxidative stress response , antioxidants , oxygen transporters , and DNA repair . These results suggest that 5 nm Ag-NPs are mutagenic in mouse lymphoma cells due to induction of oxidative stress by the Ag-NPs . Environ . Mol . Mutagen . 2012 . ( c ) 2012Wiley Periodicals , Inc .

[ Sen. 4, subscore: 1.00 ]: Although cocaine readily induces taste aversions , little is known about the mechanisms underlying this effect . It has been suggested that its inhibitory effects at one of the monoamine transporters may be mediating this suppression . Using the cross-drug preexposure preparation , the present series of studies examined a possible role of dopamine ( DA ) in this effect . Male Sprague-Dawley rats were exposed to cocaine ( 18mg/kg ; Experiment 1 ) or the selective DA transporter ( DAT ) inhibitor GBR 12909 ( 50mg/kg ; Experiment 2 ) prior to the pairing of a novel saccharin solution with injections of GBR 12909 ( 32mg/kg ) , cocaine ( 18mg/kg ) or vehicle in a conditioned taste aversion ( CTA ) procedure . Preexposure to cocaine attenuated aversions induced by itself but not aversions induced by GBR 12909 ( Experiment 1 ) . Conversely , preexposure to GBR 12909 attenuated aversions induced by itself and cocaine ( Experiment 2 ) . This asymmetry suggests that cocaine and GBR 12909 induce CTAs via similar , but non-identical , mechanisms . These data are discussed in the context of previous work demonstrating roles for dopamine , norepinephrine and serotonin in cocaine-induced CTAs .

[ Sen. 11, subscore: 1.00 ]: In the present study , KIN genes from the widespread plant Capsella bursa-pastoris were identified and analyzed to better understand the powerful adaptation of this species . Two KIN genes were cloned and sequenced by 3 RACE . As some COR genes are homologous to LEA genes , three KIN-homologous LEA genes were also identified . We deduced the amino acid sequences of the five proteins to estimate their phylogenetic relationships , and grouped them into three subfamilies ( CI , CII , and CIII ) . Variable 3 UTRs were found in CI , CII , and CIII genes . Using qPCR , we evaluated the transcriptional levels of the five genes in different organs and embryonic stages . Two CI genes were exclusively expressed in early embryos and flowers . The CII and CIII genes showed obvious up-regulation in young leaves after heat stress , cold stress , and ABA treatment . Two of the CI genes , however , rarely responded to those stresses in young leaves . In contrast , all five genes showed differential responses in flowers when C bursa-pastoris plants were sprayed with ABA . Furthermore , the expression of these genes in C bursa-pastoris was compared to that of the corresponding Arabidopsis genes , and similar gene expression profiles were found in both species . Our findings suggest that these five genes play different roles in development and the responses to abiotic stresses in C bursa-pastoris . Key message We characterized two KIN and three KIN-homologous LEA genes , and analyzed their variable 3UTR and organ-specific , embryo-developmental , stress-induced gene expression in Capsella bursa-pastoris .

[ Sen. 1, subscore: 1.00 ]: BACKGROUND : Foliar sprays of iron ( Fe ) and zinc ( Zn ) fertilisers are known to be an effective way to improve Fe and Zn concentrations in rice grain . However , results can differ significantly among different rice cultivars and/or types of foliar fertiliser . In this study , several Fe-rich rice cultivars were used to identify an effective foliar fertiliser for optimal Fe and Zn enrichment of rice grain . RESULTS : Foliar Fe amino acid ( Fe-AA ) fertiliser significantly improved the Fe concentration in brown rice of most cultivars . Compared with the control , the average Fe concentration in all tested cultivars was increased by 14 . 5% . The average Fe concentration was increased by 32 . 5% when 1% ( w/v ) nicotianamine ( NA ) was added to Fe-AA , while the average Zn concentration was increased by 42 . 4% when 0 . 5% ( w/v ) ZnSO ( 4 ) . 7H ( 2 ) O was added to Fe-AA . CONCLUSION : The results suggested that NA at a suitable concentration added to Fe-AA fertiliser could accelerate Fe accumulation in rice grain . A relatively low concentration of ZnSO ( 4 ) . 7H ( 2 ) O added to Fe-AA significantly increased Fe and Zn accumulation in rice grain . The study identified some useful foliar fertilisers for enhancing the levels of Fe and Zn in selected Fe-rich rice cultivars . Copyright ( c ) 2012 Society of Chemical Industry .

[ Sen. 8, subscore: 1.00 ]: OBJECTIVE : To describe the epidemiology of competition and training-based surf sport-related injury in Australia in the years 2003-2011 . DESIGN : A retrospective epidemiological review . METHOD : Information on surf sport-related injuries was obtained from Surf Life Saving Australias SurfGuard Incident Reporting Database during 1 January 2003 to 20 August 2011 . RESULTS : There were 2645 surf sport-related competition or training-related incidents . Males and females experienced similar proportions of injury by activity type , with older individuals experiencing a higher proportion of injuries during training than younger individuals . Minor first aid was required for 54 . 5% of the competition and 43 . 7% of the training-related incidents , with major first aid required in just over 10% of both incident types . Overall , inflatable rescue boats , beach flags , and surf boats were the most common activities performed at the time of the incident , with returning to shore and negotiating the break the most common possible contributing factors to surf boat incidents . Bruises/contusions , strains , inflammation/swelling , and sprains were the most common types of injuries that occurred during both competition and training . RICE - Rest-Ice-Compression-Elevation - was the most common form of initial treatment for the injury during both competition and training . CONCLUSIONS : Participation in surf sports is not without risk of injury . Information from this study will inform injury prevention efforts for surf sport and act as a guide for future research in this area , and towards improved injury surveillance for surf sport-related injuries .

[ Sen. 2, subscore: 1.00 ]: As a part of a cooperative study initiated to assess both in vitro and in vivo protein quality methods , the protein efficiency ratio ( PER ) and net protein ratios ( NPR ) of 15 different protein sources were determined . Male weanling Sprague-Dawley rats were fed a 10% protein diet . Fourteen-day NPR and relative NPR ( RNPR ) values and 14 and 28-day PER and relative PER ( RPER ) values were calculated for each protein source . When protein quality values were expressed relative to ANRC casein , the 14 and 28-day PER data ranked the protein sources essentially in the same order . RPER values of nonfat dried skim milk ( unheated ) and tuna were more than 100% that of casein ; nonfat dried skim milk ( heated ) , chickpeas , and breakfast sausage were between 50 and 70% of that of casein ; and pinto beans and rice-wheat gluten cereal did not support substantial growth of the rat . The NPR method did not always rank the protein sources in the same order as the PER method . For the poor quality proteins , RNPR values were much higher than the RPER values ; however , the RNPR and RPER values agreed closely for high quality protein sources .
