International Journal of Gynecology &Obstetrics, EarlyView.Abstract Objective To develop and internally validate a mechanistic, three‐domain framework for early classification and prediction of pre‐eclampsia (PE) using first‐trimester angiogenic, uteroplacental, and maternal vascular biomarkers. Methods In a prospective cohort of 1925 singleton pregnancies screened at 11 to 13.6 weeks, placental growth factor (

Nonlinear physics of electrical wave propagation in the heart: a review [PDF]
, 2016 The beating of the heart is a synchronized contraction of muscle cells (myocytes) that are triggered by a periodic sequence of electrical waves (action potentials) originating in the sino-atrial node and propagating over the atria and the ventricles ...

Endometrial Stromal Cell Senescence: A Non‐Negligible Factor in Recurrent Pregnancy Loss
iMetaMed, EarlyView.As populations age, links between female reproductive aging and infertility are increasingly evident. Cellular senescence, characterized by near‐irreversible cell‐cycle arrest and accumulation of damage, can impair tissue function. In the endometrium, aberrant senescence of endometrial stromal cells (EnSCs) may compromise receptivity, hinder embryo ...

M1/M2 Macrophage Polarity in Normal and Complicated Pregnancy [PDF]
, 2014 Tissue macrophages play an important role in all stages of pregnancy, including uterine stromal remodeling (decidualization) before embryo implantation, parturition, and postpartum uterine involution. The activation state and function of utero-placental

Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background The pulsatile expansion of pulmonary vessels carries dynamic cardiopulmonary information that may reveal disease earlier than structural changes alone. Purpose To test (i) intra‐ and inter‐scan repeatability of dynamic vessel metrics in healthy subjects, and (ii) whether chronic obstructive pulmonary disease (COPD) and postcapillary

Frontiers in Physiology, 2019 Accumulating evidence has shown that preeclampsia (PE) was associated with an aberrant maternal-fetal inflammatory response. In the present study, we first found that in human PE placentas levels of toll-like receptor 4 (TLR4), phosphorylated p38 mitogen-
