Clinical and ultrasonic estimation of fetal weight
… it is useful to make an accurate assessment of fetal weight prior to delivery. A foreknowledge of the mass of the fetus can influence management in circumstances complicated by, for example, a previous caesarean section, a breech presentation, a compromised fetus of borderline viability and a …

Accuracy of estimated fetal weight using ultrasound at term in pregnant women diagnosed with gestational and pre-gestational diabetes at Groote Schuur Hospital
… increased risk of perinatal complications with a fetal weight at birth of more than 4 000 g, especially if macrosomia occurs in the context of diabetes. In order to predict fetal macrosomia, fetal weight estimation remains an important component of antenatal surveillance. Despite the relative …

The Effect of Exercise on Blood Flow in Pregnant Guinea Pigs
<p>Recent investigations have shown decreased fetal weight in pregnant animals who were exercised regularly during pregnancy (Gilbert; Nelson; Longo, 1979; Terada, 1974). The purpose of this experimental study was to investigate fetal weight gain and measure blood flow in pregnant guinea pigs who …

Pregnancy and parturition in rats on a zinc deficient diet with varying levels of tryptophan
… gestation consumed less food and gained less weight than those on the high zinc diets. Reproductive success was less on the low zinc diet. The incidences of maternal mortality, fetal mortality, and reabsorptions were higher in the dams fed a low zinc diet. There were no significant differences …

Correlación entre el peso fetal estimado por ecografía y el peso observado al nacer en embarazadas que verifican parto abdominal por macrosomia fetal en el Hospital Nacional San Juan de Dios San Miguel en el periodo de enero a diciembre 2017.
… La estimación clínica o ecográfica del peso fetal puede tener gran utilidad en el ámbito clínico, pero es importante establecer su concordancia con el peso real en atención primaria. Objetivo: Correlacionar el peso fetal estimado por ecografía y el peso observado al nacer en embarazadas que …

The placenta in adverse maternal environments; exploring how hypoxia and food restriction limit fetal growth
… vital link between mother and fetus, supporting fetal growth through supply of oxygen and nutrients. However, it must also work to balance both maternal and fetal needs and adapt to the maternal environment to support successful pregnancy. Failure to adapt can impact maternal health and fetal …

Intrauterine position in pigs: effects on conceptus development and fetal fluids steroid content
… of pigs. six conceptus variables (placental weight, placental length, fetal weight, fetal length, allantoic fluid volume and amniotic fluid volume) and seven steroids (progesterone, androstenedione, dehydroepiandrosterone, dehydroepiandrosterone sulfate, testosterone, estrone and estrone …

The use of HbA1c in predicting excessive fetal growth in women at risk of gestational diabetes
… mellitus (GDM) is associated with excessive fetal growth in later gestation. Traditionally, GDM is diagnosed between 26-28 weeks’ gestation. Subsequent intervention aims to reduce the risk of excessive fetal growth and its associated sequelae. Recent data suggest accelerated fetal growth may …

Potentiating effects of caffeine on the teratogenicity of acetazolamide in two strains of mice
… A highly significant (P<.001) increase in fetal malformations, especially right forelimb ectrodactyly, was evident in C57BL/6J litters exposed on day 9 of gestation to both agents when contrasted with those exposed to either agent alone. Both frequency and severity of ectrodactyly was …

The impact of placental SLC2A3 (GLUT-3) RNA interference on fetal growth and physiology at mid-gestation in sheep
Glucose is the primary energy substrate for fetal oxidative processes and growth. In order for glucose to be transported from maternal to fetal circulation in the ruminant placenta, it must be sequentially transported by SLC2A1 (GLUT-1) on the maternal-fetal syncytial layer, then by SLC2A3 (GLUT-3) …

The role of folic acid supplementation on exencephaly induced by maternal exposure to sodium valproate in the TO mouse
… increase in resorption, reduction in mean fetal weight, and exencephaly of live fetuses. Exencephaly was found to be associated with several craniofacial malformations and hemorrhage. Alizarin red and alcian blue stained skeletal preparations disclosed the maxillary and mandibular …

Clinico-Chemical Parameters of Fetal Fluids and Maternal Blood in the Bovine Model: Effects of Genetics and Sex and Relationships with Feto-Placental Phenotype
… influenced by bidirectional exchange between the fetal and maternal systems that programme birth weight and postnatal phenotype. Fetal fluids are essential but unexplored areas for prenatal growth. This study examined allantoic and amniotic fluids and maternal blood in a Bos taurus, Bos indicus …

A study of acetylcholinesterase and cholinesterase in the fetal mouse brain and a study of the effects of three teratogens, vitamin A, cyclophosphamide and sodium valproate on the fetal mouse central nervous system
… cholinesterase and its isoenzymes in the fetal mouse brain, and secondly to study drug-induced fetal damage with the following objectives in mind: (i) to examine new markers for the evaluation and prediction of the teratogenic potential of drugs, and (ii) to try and throw more light on …

Ultrasound prediction of large fetuses. Epidemiological and clinical investigations
The proportions of newborns with a birth weight (BW) >4,000 g and of macrosomic newborns (BW >4,500 g) have increased during the last two decades, parallel with an increasing maternal pre-pregnancy body mass index (BMI) and age at the time for pregnancy. Delivery of a large fetus, especially >4,500 …

Fetal programming in cattle: the effects of varying maternal protein intake in adolescent beef heifers on fetal and postnatal growth and development of the calf
… status during gestation influences the fetal development, postnatal growth pathways and metabolism and reproductive development of the offspring. Wide variation in pasture quality and quantity available for the cow herd throughout the breeding season and during gestation is common in …
