Slight perturbations in maternal sex steroid production and metabolism may interfere with normal fetal neurodevelopment. The balance of maternal estrogens and androgens may have direct fetal effects, may influence the fetal hypothalamic-pituitary-gonadal axis, or may alter local hormonal activity within the fetal brain. We investigated maternal functional polymorphisms of CYP17, ...

We performed a matched case-control study to analyze the placental angioarchitecture, in particular the diameter of arterio-arterial (AA) anastomoses in monochorionic placentas from pregnancies with twin-twin transfusion syndrome (TTTS) compared to a control group of uncomplicated monochorionic placentas. Placental angioarchitecture was analyzed using colored dye injection. AA anastomoses were detected ...

Folate, a key periconceptional nutrient, is ultraviolet light (UV-R) sensitive. We therefore hypothesise that a relationship exists between sunspot activity, a proxy for total solar irradiance (particularly UV-R) reaching Earth, and the occurrence of folate-sensitive, epigenomic-related neonatal genotypes during the first trimester of pregnancy. Limited data is provided to support ...

Aim:  Genetic thrombophilias are known to contribute to adverse pregnancy outcomes. Studies in Western populations show that 5, 10-methylenetetrahydrofolate reductase (MTHFR) 677C>T and Factor V (F5) 1691G>A (Leiden) polymorphisms are commonly associated with pre-eclampsia and recurrent spontaneous pregnancy loss. The objective of this study was to investigate the association of ...

MTHFD1 encodes C1-tetrahydrofolate synthase, which is a folate-dependent enzyme that catalyzes the formation and interconversion of folate-activated one-carbon groups for nucleotide biosynthesis and cellular methylation. A polymorphism in MTHFD1 (1958G→A) impairs enzymatic activity and is associated with increased risk of adverse pregnancy outcomes, but the mechanisms are unknown. The objective ...
