BACKGROUND Several studies have reported decreases in birth size associated with exposure to organochlorine compounds (OCs), but uncertainties remain regarding the critical windows of prenatal exposure and the effects on fetal body segments. OBJECTIVE We examined the relationship between prenatal OC concentrations and fetal anthropometry. METHODS We measured 4,4´-dichlorodiphenyldichloroeth...

Fetal growth plays a role in programming of adult cardiometabolic disorders, which in men, are associated with lowered testosterone levels. Fetal growth and fetal androgen exposure can also predetermine testosterone levels in men, although how is unknown, because the adult Leydig cells (ALCs) that produce testosterone do not differentiate until puberty. To explain this conundrum, we hypothesize...

Premature rupture of fetal membranes can have serious clinical implications, especially for the initiation of preterm labour and its consequences. To account for this phenomenon many studies have attempted to identify membrane features that may be uniquely associated with the site of rupture. Our previous work has identified an area of the fetal membrane, following spontaneous term birth which ...

nowadays, new advances in the use of cell free fetal dna (cffdna) in maternal plasma of pregnant women has provided the possibility of applying cffdna in prenatal diagnosis as a non-invasive method. in contrary to the risks of invasive methods that affect both mother and fetus, applying cffdna is proven to be highly effective with lower risk. one of the applications of prenatal diagnosis is fet...

Significant spontaneous fetal loss of unknown cause occurs in North American commercial swine. About 30% of conceptuses, thought to be genetically normal, are lost during the peri-attachment period. An additional 20% are lost at mid-pregnancy. Littermate endometrial and trophoblast biopsies were studied by quantitative real-time PCR for gene expression, and immunohistochemistry for protein expr...

BACKGROUND Reduction of fetal number has been offered in high order multiple gestations but is still controversial in triplets. Since recent advances in neonatal and obstetric care have greatly improved outcome, the benefits of multifetal pregnancy reduction (MFPR) may no longer exist in triplet gestations. OBJECTIVES To evaluate if fetal reduction of triplets to twins improves outcome. MET...

Introduction Fetal exsanguination is a rare complication of cordocentesis. Successful correction of fetal thrombocytopenia is essential for the reduction of risks. Case Report A 25-year-old, gravida 3, P2-0-0-0-2, was referred at 27 weeks of gestation for evaluation of newly diagnosed nonimmune hydrops secondary to parvovirus infection. Despite the use of ancillary platelet transfusions to corr...

Introduction: Fetal heart rate and its variability during the course of gestation have been extensively researched. The overall reduction in heart rate and increase in fetal HRV is associated with fetal growth and the increase in neural integration. The increased complexity of the demands on the cardiovascular system leads to more variation in the temporal course of the heart rate which has bee...

• "When fetaJ asphyxia or hypoxia is induced by reduction of uterine and umbilical circulations oi" by administration of a gas mixture of low oxygen content to the mother, there is an increase in the fetal arterial pressure." The effects on the fetal heart rate appear to be variable. Bradycardia has been observed by several investigators.*~ Born et al. noted that the changes in heart rate depen...
