Real‐Time and High‐Resolution NIR‐II‐L Imaging of Netrin‐1‐Mediated Neurovascular Coupling Driven by Dose‐Dependent Electroacupuncture

Advanced Science, Volume 13, Issue 19, 2 April 2026.
Disrupted neurovascular coupling contributes to ovarian dysfunction in polycystic ovary syndrome. Using near‑infrared II long‑wavelength imaging, this study visualizes how electroacupuncture dynamically regulates ovarian blood vessels in vivo. Immediate and cumulative stimulation elicit distinct vascular responses via a Netrin‐1 dependent mechanism ...

Salidroside Ameliorates Polycystic Ovary Syndrome in Mice by Regulating the AKT/NF‐κB/NLRP3‐HAS2 Axis

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
Salidroside ameliorates PCOS via inhibiting the ROS‐AKT/NF‐κB axis and suppressing NLRP3 inflammasome activation. It disrupts the NLRP3–LAP‐TGFβ1 interaction to block TGF‐β‐SMAD2/3 signaling and consequent ovarian fibrosis. Together with hyaluronan synthase 2 (HAS2) downregulation, these effects alleviate inflammation and hyaluronan overaccumulation ...

Growth Differentiation Factor 9 Supplementation Restores the Lipopolysaccharide‐Induced Negative Effects on Bovine Oocyte Developmental Competence

Molecular Reproduction and Development, Volume 93, Issue 4, April 2026.
ABSTRACT Growth differentiation factor 9 (GDF9) plays a key role in enhancing developmental competence and blastocyst yield during in vitro maturation (IVM). This study investigated whether GDF9 could counteract the harmful effects of lipopolysaccharide (LPS), a gram‐negative bacterial component, on bovine in vitro embryo production, while also ...

FOLLICLE POPULATIONS IN MARE OVARIES: FROM PREANTRAL TO PREOVULATORY FOLLICLES

Enciclopédia Biosfera, 2015
The purpose of this study was to describe morphological and quantitative aspects of preantral and antral follicles in the equine ovary. Six ovaries were collected from necropsied mares and sliced lengthwise parallel to the ovulation fossa. The slices were fixed and processed for histological evaluation under light microscopy.
