Prenatal diagnosis of isovaleric acidaemia by enzyme and metabolite assay in the first and second trimesters [PDF]
, 1995 Isovaleric acidaemia (IVA) is caused by a deficiency of isovaleryl CoA dehydrogenase. The diagnosis can be established biochemically by the demonstration of increased levels of isovalerylglycine (IVG) and 3-hydroxyisovaleric acid in urine and by the ...

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies
American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...

Bridging maternal effects and epitranscriptomics: A novel perspective in developmental biology
Developmental Dynamics, EarlyView.Abstract Maternal effects, encompassing both genetic (maternally expressed gene products) and non‐genetic (maternal state) influences, are powerful determinants of offspring phenotype, yet their RNA‐level mechanisms remain incompletely resolved. In parallel, epitranscriptomics, an emerging field centered on chemical modifications to RNA, has revealed ...

Localization of matrix metalloproteinases in the placenta of cows with complicated pregnancy by placental insufficiency [PDF]
BIO Web of ConferencesThe placenta of 8 cows with physiological (PP) and placental insufficiency pregnancy (FPI) served as the material for the study. Analysis of the content of glycosaminoglycans (GAG) in the tissue of the uterine part of the placenta in cows with FPI ...

Optimal villi density for maximal oxygen uptake in the human placenta
, 2015 We present a stream-tube model of oxygen exchange inside a human placenta functional unit (a placentone). The effect of villi density on oxygen transfer efficiency is assessed by numerically solving the diffusion-convection equation in a 2D+1D geometry ...

Previable PROM in twins: A systematic review and meta‐analysis
International Journal of Gynecology &Obstetrics, EarlyView.Abstract Background Previable prelabor rupture of membranes (PROM) in twin pregnancies is a rare but high‐risk condition associated with substantial neonatal mortality and maternal morbidity. Management options include expectant management and selective reduction, though guidance is limited and based primarily on singleton data.

Cells, 2019 The cytotrophoblast of human placenta transitions into an outer multinucleated syncytiotrophoblast (STB) layer that covers chorionic villi which are in contact with maternal blood in the intervillous space. During pregnancy, the Zika virus (ZIKV) poses a
