| Title: Identification of dietary patterns using factor analysis in an epidemiological study in So Paulo .
| | Author: Marchioni DM Latorre Mdo R Eluf-Neto J WEsch-Filho V Fisberg RM .
| | Journal: Citation: V : 123 ( 3 ) P : 124-7 Year: 2005 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub16021275 Accession (PMID): 16021275 | | Abstract: CONTEXT AND OBJECTIVE : Diet and nutrition are environmental factors in health/disease relationships .
From the epidemiological viewpoint , diet represents a complex set of highly correlated exposures .
Our objective was to identify patterns of food intake in a group of individuals living in So Paulo , and to develop objective dietary measurements for epidemiological purposes .
DESIGN AND LOCAL : Exploratory factor analysis of data in a case-control study in seven teaching hospitals in So Paulo .
METHODS : The participants were 517 patients ( 260 oral cancer cases and 257 controls ) admitted to the study hospitals between November 1998 and March 2001 .
The weekly intake frequencies for dairy products , cereals , meat , processed meat , vegetables , pulses , fruits and sweets were assessed by means of a semi-quantitative food frequency questionnaire .
Dietary patterns were identified by factor analysis , based on the intake of the eight food groups , using principal component analysis as an extraction method followed by varimax rotation .
RESULTS : Factor analysis identified three patterns that accounted for 55% of the total variability within the sample .
The first pattern ( "prudent" ) was characterized by vegetable , fruit and meat intake ; the second ( "traditional" ) by cereals ( mainly rice ) and pulses ( mainly beans ) ; and the third ( "snacks" ) by dairy products and processed meat .
CONCLUSION : This study identified food intake patterns through an a posteriori approach .
Such analysis may be useful for nutritional intervention programs and , after computing scores for each individual according to the patterns identified , for establishing a relationship between diet and other epidemiological measurements of interest | Matching Sentences:

| Title: Trichoderma theobromicola and T paucisporum : two new species isolated from cacao in South America .
| | Author: Samuels GJ Suarez C Solis K Holmes KA Thomas SE Ismaiel A Evans HC .
| | Journal: Mycol . Res . Citation: V : 110 ( Pt 4 ) P : 381-92 Year: 2006 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub16621496 Accession (PMID): 16621496 | | Abstract: Trichoderma theobromicola and T paucisporum spp . nov . are described .
Trichoderma theobromicola was isolated as an endophyte from the trunk of a healthy cacao tree ( Theobroma cacao , Malvaceae ) in Amazonian Peru ; it sporulates profusely on common mycological media .
Trichoderma paucisporum is represented by two cultures that were obtained in Ecuador from cacao pods partially infected with frosty pod rot , Moniliophthora roreri ; it sporulates sporadically and most cultures remain sterile on common media and autoclaved rice .
It sporulates more reliably on synthetic low-nutrient agar ( SNA ) but produces few conidia .
Trichoderma theobromicola was reintroduced into cacao seedlings through shoot inoculation and was recovered from stems but not from leaves , indicating that it is an endophytic species .
Both produced a volatile/diffusable antibiotic that inhibited development of M roreri in vitro and on-pod trials .
Neither species demonstrated significant direct in vitro mycoparasitic activity against M roreri .

| | Author: Chung IM Ali M Ahmad A Chun SC Kim JT Sultana S Kim JS Min SK Seo BR | | Journal: Phytochem Anal Citation: V : 18 P : 133-45 Year: 2007 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub17439014 Accession (PMID): 17439014 | | Abstract: Two new compounds , 14-methyl stigmast-9 ( 11 ) -en-3alpha-ol-3beta-D-glucopyranoside ( 1 ) and cholest-11-en-3beta , 6beta , 7alpha , 22beta-tetraol-24-one-3beta-palmitoleate ( 2 ) , along with the known compound beta-sitosteryl-3beta-D-glucopyranosyl-6-linoleiate ( 3 ) , were isolated from the methanolic extract of rice ( Oryza sativa ) hulls .
The structures of the two new compounds were elucidated using one and two-dimensional NMR in combination with IR , EI/MS , FAB/MS , HR-EI/MS and HR-FAB/MS .
In bioassays with blue-green algae , Microcystis aeruginosa UTEX 2388 and duckweed , Lemna paucicostata Hegelm 381 , the efficacy of bioactivity of the two new compounds linearly increased as the concentration increased from 0 . 3 to 300 IgM .
Compared with momilactone A , compounds 1 and 2 showed similar and higher inhibitory activities against the growth of M aeruginosa at a concentration of 300 microM .
However , compound 2 was similar to momilactone A in inhibiting L paucicostata growth at a concentration of 300 microM .
As a result , compound 2 appears to have a strong potential for the environmentally friendly control of weed and algae that are harmful to water-logged rice .

| Title: Dietary patterns in Japanese migrants to southeastern Brazil and their descendants .
| | Author: Cardoso MA Hamada GS de Souza JM Tsugane S Tokudome S | | Journal: Citation: V : 7 ( 4 ) P : 198-204 Year: 1997 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub9465543 Accession (PMID): 9465543 | | Abstract: This paper describes the dietary patterns of people of Japanese ancestry living in So Paulo , Brazil .
Two cross-sectional surveys using a food frequency questionnaire ( in 1989 and 1995 ) and self-administered three-day food record ( only in 1995 ) were carried out in randomly chosen first-generation ( Japan-born ) and second-generation ( Brazil-born ) Japanese living in the city of So Paulo ( n = 166 ) , aged 40-69 years at the time of the first survey ( 1989 ) .
Daily intake of rice , bread , milk , fruits and coffee , and infrequent consumption of pork , green tea , black tea , tsukemono ( pickled vegetables ) , seaweed and mushrooms were reported .
The mean ( +/- standard deviation ) daily proportions of energy from fat among Japan-born participants were 27 . 2 +/- 6 . 7% for men and 26 . 2 +/- 6 . 7% for women .
The respective figures for Brazil-born Japanese were 30 . 1 +/- 7 . 4% and 29 . 5 +/- 6 . 4% .
These values were quite close to recent estimates for the general Brazilian population in metropolitan areas ( about 30% ) , but seem to be higher than available data from Japan ( 25 . 3% ) .
Dietary changes in this migrant population are discussed with focus on nutrients currently implicated in the etiology of major chronic diseases .

The experiments aimed at determining the vectorial capacity of this species .
METHODS : During the summer ( January , February and March ) , three marking-release-recapture experiments with field and laboratory reared populations were conducted to evaluate the population size .
Simultaneous human bait collections were also carried out to estimate the human biting rate .
RESULTS : The population sizes of the three experiments were estimated to be 64 , 560 , 50 , 503 and 22 , 684 mosquitoes .
The bite/man/night rate varied from 41 . 5 to 524 , 5 .
DISCUSSION : The results indicated high mosquito density in the summer which allow one to infer that , even though the survival rate is low , the number of remaining females is large enough to outlive the parasites extrinsic developmental period .

| Title: [ Mite contamination in polished rice and beans sold at markets ] | | Author: Franzolin MR Baggio D | | Journal: Citation: V : 34 ( 1 ) P : 77-83 Year: 2000 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub10769365 Accession (PMID): 10769365 | | Abstract: OBJECTIVE : To evaluate mite contamination rate in grains commercialized in nine municipal markets of the city of So Paulo , in the period from November 1989 to November 1990 .
METHODS : 23 samples of polished rice and 53 samples of beans were microscopically examined after sieving , once a week and during 42 days at air temperature .
Other sample fractions were kept in an incubator at 25 degrees C and 75% Relative Humidity ( RH ) during 28 days .
RESULTS : Samples were negative for mites in the first day of analysis and were detected after incubation .
Samples incubated revealed a higher percentage of positive examinations for mites ( incidence ) : 31 . 7% ( and 1 , 845 mites ) ; while samples kept at air temperature showed only 6 . 9% ( and 45 mites ) .
Samples of polished rice were more contaminated in comparison to the ones of beans .
There was a larger amount of mites when the mean monthly temperature of the laboratory was between 21 . 5 degrees C to 22 . 5 degrees C ( 37 .
8% ) and humidity between 73 . 5% to 74 . 5% ( 31 . 1% ) .
CONCLUSIONS : The predominant species was Tyrophagus putrescentiae and other identified species were Blomia tropicalis , Cheyletus spp . , Blattisocius tarsalis , and others .
Mite population had a higher proliferation rate during spring , summer and in the beginning of autumn , due to highest temperature and humidity .
These results confirm the importance of improving grains storage , to avoid mites proliferation . | Matching Sentences:

| Title: Design strategy for assessing multi-pathway exposure for children : the Minnesota Childrens Pesticide Exposure Study ( MNCPES ) .
| | Author: Quackenboss JJ Pellizzari ED Shubat P Whitmore RW Adgate JL Thomas KW Freeman NC Stroebel C Lioy PJ Clayton AC Sexton K | | Journal: Citation: V : 10 ( 2 ) P : 145-58 Year: Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub10791596 Accession (PMID): 10791596 | | Abstract: Although children are exposed to a variety of environmental hazards , including pesticides , there is a scarcity of information available to estimate exposures realistically .
This article reports on one of the first attempts to measure multi-pathway pesticide exposures in a population-based sample of urban and non-urban children .
A design strategy was developed to assess multi-pathway pesticide exposures in children using personal exposure measurements in combination with complimentary measurements of biological markers of exposure , concentrations in relevant environmental media , and time spent in important microenvironments and participating in exposure-related activities .
Sample collection and analysis emphasized measurement of three insecticides ( ie , chlorpyrifos , diazinon , and malathion ) and one herbicide ( ie , atrazine ) .
These compounds were selected because of their frequent use , presence in multiple environmental media , expected population exposures , and related hazard/toxicity .
The study was conducted during the summer of 1997 in Minnesota and involved a stratified sample of households with children ages 3-12 years .
Participants resided in either ( a ) the cities of Minneapolis and St Paul ( urban households ) , or ( b ) Rice and Goodhue Counties just south of the metropolitan area ( non-urban households ) .
Results from a residential inventory documenting storage and use of products containing the target pesticides were used to preferentially select households where children were likely to have higher exposures .
The study successfully obtained pesticide exposure data for 102 children , including measurements of personal exposures ( air , hand rinse , duplicate diet ) , environmental concentrations ( residential indoor/outdoor air , drinking water , residential surfaces , soil ) , activity patterns ( obtained by questionnaire , diary , videotaping ) , and internal dose ( metabolites in urine ) .

| Title: Preferential occurrence of diazotrophic endophytes , Azoarcus spp . , in wild rice species and land races of Oryza sativa in comparison with modern races .
| | Author: Engelhard M Hurek T Reinhold-Hurek B | | Journal: Environ . Microbiol . Citation: V : 2 ( 2 ) P : 131-41 Year: 2000 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub11220300 Accession (PMID): 11220300 | | Abstract: Several diazotrophic species of Azoarcus spp . occur as endophytes in the pioneer plant Kallar grass .
The purpose of this study was to screen Asian wild rice and cultivated Oryza sativa varieties for natural association with these endophytes .
Populations of culturable diazotrophs in surface-sterilized roots were characterized by 16S rDNA sequence analysis , and Azoarcus species were identified by genomic fingerprints .
A indigens and Azoarcus sp . group C were detected only rarely , whereas Azoarcus sp . group D occurred frequently in samples of flooded plants : in 75% of wild rice , 80% of land races of O sativa from Nepal and 33% of modern cultivars from Nepal and Italy .
The putatively endophytic populations of diazotrophs differed with the rice genotype .
The diversity of cultured diazotrophs was significantly lower in wild rice species than in modern cultivars .
In Oryza officinalis ( from Nepal ) and O minuta ( from the Philippines ) , Azoarcus sp . group D were the predominant diazotrophic putative endophytes in roots .
In contrast , their number was significantly lower in modern cultivars of O sativa , whereas numbers and diversity of other diazotrophs , such as Azospirillum spp . , Klebsiella sp . , Sphingomonas paucimobilis , Burkholderia sp . and Azorhizobium caulinodans , were increased .
In land races of O sativa , the diazotrophic diversity was equally high ; however , Azoarcus sp . was found in high apparent numbers .
Similar differences in populations were also observed in a culture-independent approach comparing a wild rice ( O officinalis ) and a modern-type O sativa plant : in clone libraries of root-associated nitrogenase ( nifH ) gene fragments , the diazotrophic diversity was lower in the wild rice species .
New lineages of nifH genes were detected , eg one deeply branching cluster within the anf ( iron ) nitrogenases .
Our studies demonstrate that the natural host range of Azoarcus spp . extends to rice , wild rice species and old varieties being preferred over modern cultivars . | Matching Sentences:
