Perinatal Outcome of Twin Pregnancies Compared based on Chorionicity and Antenatal Booking Status of Mother [PDF]
Journal of Clinical and Diagnostic Research, 2019 Introduction: Twin pregnancy is considered a high risk pregnancy due to multiple maternal and foetal complications leading to adverse maternal and foetal outcome.

Advanced Science, EarlyView.SDF‐1 levels decline significantly with maternal aging. Exogenous supplementation restores meiotic spindle morphology, chromosomal alignment, and mitochondrial function while reducing oxidative stress in aged oocytes. Mechanistically, SDF‐1 enhances autophagic activity to clear accumulated stress granules, thereby rescuing fertilization competence and ...

m6A‐Driven Pexophagy Triggers Placental Ferroptosis to Impair Fetal Growth Upon Environmental Stress
Advanced Science, EarlyView.Prenatal environmental stress exposure promotes m6A modification to drive PEX2‐dependent pexophagy, thereby causing placental ferroptosis and FGR. ABSTRACT The role and underlying mechanisms of placental ferroptosis in fetal growth restriction (FGR) induced by environmental stress remain poorly understood.

Collective utility of NIPT zygosity determination and chorionicity assignment via ultrasound: 917
American Journal of Obstetrics and Gynecology, 2019 •This study represents the only cohort of twins for which NIPT-based zygosity was correlated with provider-assigned chorionicity. •Among samples with unspecified/unreported chorionicity identified as monozygous by NIPT, early/accurate chorionicity ...

Compact 9dBEs Enable Efficient and Precise Genome Editing in Mammalian Cells and In Vivo
Advanced Science, EarlyView.As a compact type II‐D system, the Cas9d‐based platform holds great potential for in vivo applications. Through rational engineering, its derived base editors (9dBEs) enable efficient disease modeling while facilitating single‐vector AAV delivery for in vivo genome editing. These miniature tools offer a robust strategy for basic research and biomedical

Journal of Obstetrics and Gynaecology Research, 2018 The decrease in pH in monochorionic (MC) second twin may exceed that of dichorionic (DC) second twin during vaginal twin delivery. The aim of this study was to investigate the effect of chorionicity on the umbilical artery pH of the second twin in ...

Advanced Science, EarlyView.NSUN2 and m5C decline in URSA villous tissues. Trophoblast Nsun2 ablation disrupts macrophage‐mediated maternal‐fetal tolerance and triggers embryo resorption. Mechanistically, NSUN2‐YBX1 axis stabilizes m5C‐modified TGFB1 mRNA to maintain TGF‐β1 secretion and M2 polarization, and restoring this signaling rescues maternal‐fetal immune tolerance to ...
