Gestational Hypoxia Disrupts Medial Ganglionic Eminence Progenitor Dynamics and Interneuron Development in Schizophrenia

open access: yesAdvanced Science, EarlyView.
FES‐derived MGE spheroids exhibit progenitor‐stage alterations in developmental trajectory and hypoxia‐responsive transcriptional programs, followed by functional disruption. Gestational hypoxia recapitulates impaired progenitor proliferation, shortened cell‐cycle progression, interneuron developmental abnormalities, and schizophrenia‐like behaviors in

Uterine wall thickness at the second trimester can predict subsequent preterm delivery in pregnancies with adenomyosis

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2019
Objectives: We assessed the usefulness of ultrasonography (USG) findings of adenomyosis during pregnancy in the prediction of subsequent preterm delivery.

Patterns of Cardiovascular Risk Factors in the Years Before Pregnancy in Nulliparous Women With and Without Preterm Birth and Small‐for‐Gestational‐Age Delivery

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Women with either preterm or small‐for‐gestational‐age (SGA) delivery have an elevated lifetime risk of cardiovascular disease that has been attributed to the accrual of vascular risk factors over time.

Delayed Recognition of Maternal G6PD Heterozygous Status Across Prenatal and Newborn Care Interfaces

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Glucose‐6‐phosphate dehydrogenase (G6PD) deficiency is the most common red blood cell enzymatic disorder worldwide. Although many heterozygotes are asymptomatic, affected neonates have an increased risk for hyperbilirubinemia and related complications.

Enhanced expression of transient receptor potential channel 3 in uterine smooth muscle tissues of lipopolysaccharide-induced preterm delivery mice [PDF]

open access: yesIranian Journal of Basic Medical Sciences, 2016
Objective(s): We aimed to investigate the influence of transient receptor potential channel 3 (TRPC3) on lipopolysaccharide-induced (LPS) preterm delivery mice. Materials and Methods: Mice were randomly assigned to the four groups: an unpregnant group, a

Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection

open access: yesThe Anatomical Record, EarlyView.
Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.

Reference population for international comparisons and time trend surveillance of preterm delivery proportions in three countries

open access: yesBMC Women's Health, 2008
Background International comparison and time trend surveillance of preterm delivery rates is complex. New techniques that could facilitate interpretation of such rates are needed.

Twin pregnancies and the limits of the energetics of gestation and growth hypothesis

open access: yesThe Anatomical Record, EarlyView.
Abstract The “Energetics of Gestation and Growth” (EGG) hypothesis proposes that human birth timing and the associated secondary altriciality of human newborns is determined by limits in maternal metabolic capacity. According to this model, labor is triggered when the increasing fetal energy requirements exceed the expectant mother's maximum sustained ...
