Metroplasty before IVF in women with a T‐shaped uterus: A clinical challenge

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract A T‐shaped uterus is a uterine malformation, which can be either congenital or acquired, potentially impairing fertility and increasing the risk of miscarriage. Diagnosis primarily relies on three‐dimensional ultrasound and hysteroscopy. Hysteroscopic metroplasty is the standard surgical intervention aimed at restoring normal uterine anatomy ...

Endometrial Stromal Cell Senescence: A Non‐Negligible Factor in Recurrent Pregnancy Loss

open access: yesiMetaMed, 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 ...

The recruitment and activation of phosphatidylinositol 4-phosphate 5-kinases α critically regulate CD28-dependent signaling responses [PDF]

open access: yes, 2013
CD28 costimulatory receptor is a crucial determinant of the outcome of T lymphocyte activation. The engagement of CD28 by its natural ligands, B7.1/CD80 or B7.2/CD86, expressed on the surface of professional APC, lowers T cell receptor (TCR) activation ...

Organoids and organ‐on‐a‐chip models for investigating the pathophysiology of the human reproductive system

open access: yesInterdisciplinary Medicine, EarlyView.
Organoids and organ‐on‐a‐chips are advancing reproductive system research. In the female reproductive system, applications include cancer organoid models, placental chips, and hormone simulation models. For the male reproductive system, research focuses on drug resistance mechanisms, co‐culture platforms, and infertility studies. These refined in vitro

Nanoformulated Diacerein Alleviates Hyperlipidemia via Gut Microbiota Modulation In Vivo

open access: yesNano Select, EarlyView.
A nanoformulation of diacerein (Nano‐DIA) was fabricated with carboxymethyl cellulose, achieving enhanced solubility and rapid dissolution for alternative anti‐hyperlipidemia therapeutics. Mechanistic studies revealed its in vivo lipid‐lowering efficacy is through metabolite‐mediated and microbiota‐dependent manner, highlighting its dual action on host
