lamb survival is one of the major factors affecting overall sheep productivity. lamb survival affected by environmental effect such as management, birth-type, year, season of birth, dam-age, maternal behavior, genotype of parents, and birth-weight. the data comprised 9989 records were collected from 1989 to 2009 in iranian baluchi sheep at abbasabad sheep breeding station. four binary traits cr...

low birth weight ( lbw, birth weight<2500g) is a significant health problem of children. many studies have made it apparent that there is a direct relationship between low birth weight and infant motality. one of the most important measurements to prevent children morbidity is growth monitoring and the present study was set up to compare the growth indexes of 2 year old children born with low w...

The authors discuss how the sibship design can be used to detect and control for familial confounding. Family-level confounding is especially problematic when estimating modest individual-level effects in the presence of familial confounders with large effects. This circumstance arises frequently in studies which relate indicators of fetal growth, such as birth weight, to outcomes that are stro...

OBJECTIVES Our purpose was to evaluate the benefits of cycled light (CL) versus near darkness (ND) on health in preterm infants born at <31 weeks' gestational age. STUDY DESIGN Randomized, interventional study comparing infants receiving (1) CL from birth, (2) CL at 32 weeks' postconceptional age (PCA), and (3) CL at 36 weeks' PCA in transition for discharge home. Statistical significance was...

background: feeding intolerance is prevalent in very low birth weight (vlbw) neonates and is a barrier for better and faster growth in these neonates. some studies have supported the administration of oral probiotic to decrease feeding intolerance. the aim of this study was to evaluate the effect of probiotic on feeding intolerance in vlbw neonates. methods: this randomized clinical trial study...

background   lipoprotein lipase activity can be increased by clofibrate. clofibrate is used to reduce serum triglyceride level in adults. the aim of this study was to determine the effect of clofibrate on serum triglyceride and cholesterol level after administration of intravenous lipid in very low birth weight neonates. method in a randomized double blind placebo – controlled study, 60 very lo...

background: low birth weight is one of the key indicators to assess the health of infants, and appropriate birth weight is one of the most important goals of any health system which also reflects the quality of prenatal care. objectives: the present research aimed to study some of the factors associated with low birth weight using quantile regression analysis. methods: a cross-sectional study w...

background: health status of offspring is programmed by maternal diet throughout gestation and lactation. the present study investigates the lasting effects of maternal supplementation with different amounts of soy oil or extra virgin olive oil (evoo) on weight and biochemical parameters during gestation and lactation of female mice offspring. methods: eight weeks old female c57bl/6 mice (n=40)...
