OBJECTIVES This study was aimed at establishing an ideal method for performing three-dimensional measurements of the fetus in order to improve the estimation of fetal weight. METHODS The study consisted of two phases. Phase I was a prospective cross-sectional study performed between 28 and 40 weeks' gestation. The study population (n=110) comprised low-risk singleton pregnancies who underwent...

There are morphological and reproductive physiological differences between swamp buffalo (Bubaluscarabanensis) and river buffalo (Bubalus bubalis). The development of fetus weight and fetus biometry wasreported in river buffalo and other animals but not in swamp buffalo. The aim of this study was to describethe inherent variability in fetus related measurements during swamp buffalo pregnancy. T...

Background: Birth weight are the major factors determining the physical and mental development of infants and credible signs of intrauterine growth. The purpose of this study was the Study of birth weight on maternal and neonatal factors in the women referred to delivery room of Specialized Hospital in 2010. Materials and Methods: In this cross sectional study, 3076 women with the normal vagina...

In a series of matings between congenic strains of mice, differing at the H-2 or H-3 histocompatibility loci, decidual weight and lumbar and caudal lymph-node weight on the 7th day of pregnancy and placental and fetal weight and lumbar and caudal lymph-node weight on the 18th day of pregnancy were measured. There was no evidence that antigenic differences between mother and fetus at these loci ...

The objective of this study was to evaluate the effects of parenteral administration of L-arginine (Arg) to well-fed twin-bearing ewes from day (d) 100 of pregnancy to birth on fetal growth, body composition and neonatal behavior. Ewes received an i.v. bolus of either 345 μmol Arg-HCl/kg bodyweight or saline solution (control) 3 times a day. At d 140 of pregnancy, Arg-supplemented and control e...

OBJECTIVE Low birth weight is associated with an increased risk of type 2 diabetes. The mechanisms underlying this association are unknown and may represent intrauterine programming or two phenotypes of one genotype. The fetal insulin hypothesis proposes that common genetic variants that reduce insulin secretion or action may predispose to type 2 diabetes and also reduce birth weight, since ins...

Rats were mated for two or 15 hours and variability of day-12-embryos in weight, protein content, and [3H]thymidine incorporation was compared in the long mating period (LMP) and short mating period (SMP) groups by a 2-level nested analysis of variance. Variability in day-20 fetal weight was similarly compared. In both groups day-12 embryonic weight was relatively more variable than day-20 feta...

We examined associations of maternal age at childbearing (MAC) with gestational age and fetal growth (i.e., birth weight adjusting for gestational age), using two genetically informed designs (cousin and sibling comparisons) and data from two cohorts, a population-based Swedish sample and a nationally representative United States sample. We also conducted sensitivity analyses to test limitation...
