Pregnancy is associated with a significant increase in uteroplacental blood flow (UBF), which is responsible for delivering adequate nutrients and oxygen for fetal and placental growth. The present study was designed to determine the effects of vascular insufficiency on fetal and placental growth. Thirty-nine late-term pregnant ewes were instrumented to investigate the effects of chronic UBF re...
We utilized a vitamin D receptor (VDR) gene knockout model to study the effects of maternal and fetal absence of VDR on maternal fertility, fetal-placental calcium transfer, and fetal mineral homoeostasis. Vdr null mice were profoundly hypocalcemic, conceived infrequently, and had significantly fewer viable fetuses in utero that were also of lower body weight. Supplementation of a calcium-enric...
Macrosomic infants and their mothers are at increased risk for intrapartum injury and perinatal morbidity and mortality. This study investigates the effectiveness of individual ultrasound fetal measurements, ponderal indices and estimated fetal weight in the identification of macrosomia in 732 pregnant patients who underwent ultrasound examination within 7 days of delivery. All the indices eval...
Background and purpose: Since estimation of weight in study of intrautrine growth retardation (ÏÜGR) is important therefore this study was conducted due to importance of weight in premature fetus and macrosomia and estimation of weight in mothers with premature rupture of membranes (PRÔM). Ïn this propective study it was tried to find out the best and possible formula to estimale the fetal...
BACKGROUND Human males are more vulnerable to adverse conditions than females starting early in gestation and continuing throughout life, and previous studies show that severe food restriction can influence the sex ratios of human births. It remains unclear, however, whether subtle differences in caloric intake during gestation alter survival of fetuses in a sex-specific way. I hypothesized tha...
