| Title: Copper status of ewes fed increasing amounts of copper from copper sulfate or copper proteinate .
| | Journal: J Anim . Sci . Citation: V : 77 ( 1 ) P : 244-9 Year: 1999 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub10064051 Accession (PMID): 10064051 | | Abstract: The Cu status of mature , crossbred ewes fed two sources ( CuSO4 vs Cu proteinate ) and three levels ( 10 , 20 , or 30 mg/kg ) of dietary Cu was determined in a 73-d feeding trial Ewes ( n = 30 ) were fed a basal diet containing rice meal feed , cottonseed hulls , cottonseed meal , meat and bone meal , cracked corn , and vitamin-mineral supplements at 2 . 5% of BW to meet NRC requirements for protein , energy , macrominerals , and microminerals , excluding Cu .
The basal diet contained 5 mg/kg Cu , 113 mg/kg Fe , . 1 mg/kg Mo , and . 17% S Copper sulfate or Cu proteinate was added to the basal diet to supply 10 , 20 , or 30 mg/kg of dietary copper in a 2x3 factorial arrangement of treatments .
Ewes were housed in 3 . 7 x 9 . 1-m pens in an open-sided barn .
Blood samples were collected on d 28 and 73 .
Ewes were slaughtered on d 74 , and liver and other it issues were collected to determine Cu concentrations .
An interaction ( P = . 08 ) occurred between source and level for liver Cu .
The interaction existed due to an increase in liver Cu concentrations when ewes were fed increasing dietary Cu from CuSO4 but not when fed Cu proteinate diets .
There was no source x level interaction ( P> . 10 ) for the blood constituents measured .
On d 73 , plasma ceruloplasmin activity was greater ( P< . 05 ) in ewes fed Cu proteinate than in those fed CuSO4 ( 33 . 1 vs 26 . 8 microM x min ( -1 ) x L ( -1 ) ) .
Increasing the concentration of dietary Cu did not affect ( P> . 10 ) plasma ceruloplasmin .
Packed cell volume ( PCV ) , red blood cell count ( RBC ) , white blood cell count , whole blood hemoglobin ( wHb ) , plasma hemoglobin , and plasma Cu were similar between sources of Cu .
Ewes fed 20 mg/kg Cu had lower ( P< . 05 ) PCV , RBC , and wHb than those fed 10 or 30 mg/kg Cu diets .
Feeding up to 30 mg/kg Cu from these sources did not cause an observable Cu toxicity during the 73-d period .

Sixty Holstein-Friesian crossbred cows on 11 smallholder farms were divided equally into control , UMMB and UTRS supplementation groups .
Milk yield and feed intake were recorded daily .
Milk fat content , body weight and body condition score ( BSC ) of each cow were determined at two week intervals .
Milk samples for progesterone analysis were collected once a week commencing one month after parturition .
Data were recorded for date of onset of ovarian activity , estrus , insemination , and conception rate .
Milk production increased by 10 . 3-11 . 9% and milk fat content increased by 3-5% , therefore , profit for farmers increased by US $0 . 55-0 . 73 per cow per day ( exchange rate US $1 = VN $11 , 000 ) .
The intervals from calving to onset of ovarian activity ( 91-94 days ) , to estrus ( 110-114 days ) , to conception ( 121-122 days ) and the calving interval ( 13 . 4-13 . 6 months ) in the trial groups were significantly shorter than those in the control group ( 112 , 135 , 152 days and 14 . 4 months , respectively . | Matching Sentences:

| | Journal: Acta Crystallogr .
D Biol . Crystallogr . Citation: V : 55 ( Pt 1 ) P : 77-84 Year: 1999 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub10089397 Accession (PMID): 10089397 | | Abstract: Rice dwarf virus crystals belong to space group I222 with cell parameters a = 770 ( 2 ) , b = 795 ( 5 ) , c = 814 ( 5 ) A and alpha = beta = gamma = 90 degrees .
The unit cell of the crystal contains two viruses at the origin and body-centred positions .
Using data synthesized from a rice dwarf virus model crystal in the space group I222 , the possibility of ab initio phasing was thoroughly examined .
The centric nature of the initial phases was unexpectedly broken by extensive iteration of the non-crystallographic symmetry averaging .
The structure of rice dwarf virus was then solved with ab initio phasing up to 20 A resolution .
The triangulation number determined by the present study is T = 13 , which is different from the triangulation number , T = 9 , previously determined by electron microscopy [ Uyeda & Shikata ( 1982 ) .

| Title: Zinc supplementation in malnourished children with persistent diarrhea in Pakistan .
| | Journal: Pediatrics Citation: V : 103 ( 4 ) P : e42 Year: 1999 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub10103334 Accession (PMID): 10103334 | | Abstract: OBJECTIVE : To evaluate the potential benefit of dietary supplementation of a rice-lentil ( Khitchri ) and yogurt diet with 3 mg/kg/d of elemental zinc ( as zinc sulfate ) in hospitalized malnourished children ( age 6-36 months ) with persistent diarrhea for 14 days .
METHODOLOGY : Randomized , double-blind placebo-controlled trial SETTING : Nutrition Research Ward at the National Institute of Child Health , Karachi , Pakistan , where children were admitted for 14 days of inpatient supervised rehabilitation .
MAIN OUTCOME MEASURES : Primary outcome : overall weight gain by day 14 .
Secondary outcomes : overall energy intake , stool output , time to diarrheal recovery and weight gain ( >/=3 days ) , plasma zinc , copper , prealbumin , and insulin-like growth factor-1 .
RESULTS : Of 87 children randomized for supplementation with either zinc or placebo , the two groups were comparable at admission in terms of severity and duration of diarrhea , as well as nutritional and anthropometric parameters .
The overall weight gain , stool volume , stool frequency , as well as the time taken for diarrheal recovery or steady weight gain , were comparable for both supplemented children and controls .
Supplemented children had a significant improvement in plasma zinc levels and serum alkaline phosphatase by day 14 of therapy in comparison with controls .
Plasma copper levels were low in both groups at admission and although an increase was seen in control children , levels decreased further after zinc supplementation .
There was no significant difference between the two groups for hemoglobin , serum albumin , prealbumin , and plasma insulin-like growth factor-1 increments during the course of therapy .
Evaluation of primary and secondary outcome criteria among the subset of children with plasma zinc levels <60 microg/d at admission did not reveal any significant differences .
CONCLUSIONS : Although there was satisfactory recovery in malnourished children with persistent diarrhea receiving the Khitchri-yogurt diet , there was no evidence of improved weight gain or acceleration of recovery from diarrhea with zinc supplementation .
In contrast , the reduction in plasma copper levels in zinc-supplemented malnourished children suggests that caution should be exercised in supplementing severely malnourished children with zinc alone . | Matching Sentences:

| Title: The effects of climatic patterns and agricultural practices on the population dynamics of Culex tritaeniorhynchus in Asia .
| | Journal: Southeast Asian J Trop . Med . Public Health Citation: V : -1 P : 61-71 Year: 1976 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub1027111 Accession (PMID): 1027111 | | Abstract: Annual population curves for C tritaeniorhynchus are presented for representative localities distributed from Pakistan , east through Southeast Asia and the Philippines and north to Japan and Korea .
In the dry temperature ( Pakistan ) and colder maritime climates ( Japan and Korea ) .
C tritaeniorhynchus populations apparently overwintered as hibernating adults , while in the warmer maritime climates ( Okinawa and Taiwan ) , gonotrophic activity and larval development continued throughout the winter months .
In these climatic types , the population curves closely paralleled the annual temperature curves .
In the tropical climates , however , temporal population patterns were closely related to available moisture either in the form of annual precipitation and/or rice irrigation .
The extremely variable environmental conditions tolerated C tritaeniorhynchus throughout its distribution attests to the physiological and ecological plasticity of this species and suggests that further ecological and genetic studies may reveal marked clinical variances among selected biological parameters .

| Title: Quantitative genetically nonequivalent reciprocal crosses in cultivated plants .

Citation: V : 8 ( ) P : 269-80 Year: Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub1032105 Accession (PMID): 1032105 | | Abstract: Quantitative expressions of character difference between reciprocal crosses have been studied by different researchers in a number of plant species , such as Epilobium , Zea mays , Oryza sativa , Hordeum sativum , Triticum aestivum , Trifolium hybridum , Linum usitatissimum , Nicotiana rustica , and others .
In all cases it was found that the nonequivalence of reciprocal crosses manifested itself beginning with the F1 generation , with the exception of some flax crosses in which reciprocals differed beginning with the F2 generation .
The nonequivalence of reciprocal crosses usually manifested itself in the inequality of their F1 and/or F2 or backcross means ; however , there were instances in which their means were the same but the variances were different .
Both matroclinous and patroclinous inheritances were reported in plants .
Because of the casual complexity of reciprocal differences the experimental results often lack a simple explanation . | Matching Sentences:
