The mitochondrial DNA copy number and ovary‐related reproductive disorders: A bidirectional two‐sample Mendelian randomization study

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 112-120, April 2025.
Abstract Objective In the present study, a bidirectional two‐sample Mendelian randomization approach was utilized to explore potential causal relationships between mitochondrial DNA copy number (mtDNA‐CN) and ovary‐related reproductive disorders (ORRDs), including ovarian dysfunction, ovarian cyst, polycystic ovary syndrome (PCOS), premature ovarian ...

Pelvic venous disorders in women: Diagnosis and management for gynecologists

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Pelvic venous disorders (PeVD) are an underrecognized yet significant cause of chronic pelvic pain (CPP) in reproductive‐aged women, characterized by venous reflux, obstruction, or both. This clinical opinion provides a practical overview of PeVD for gynecologists, outlining its pathophysiology, common presentations, diagnostic approach, and ...

Morphological measurements, gonadal development and estimated age of adult milkfish, Chanos chanos captured in Pandan Bay from 10 May - 16 June, 1975 [PDF]

, 1976
From 10 May to 16 June, 1975, 106 adult milkfish were captured in an otoshi-ami 500 meters offshore. Of the 106 specimens, 37 were females in various stages of gonadal development or spent and 69 were males of which 41 were sexually mature.

Decidual macrophage‐mediated ferroptosis in trophoblasts leads to recurrent spontaneous abortion

iMeta, EarlyView.
Decidual macrophages from recurrent spontaneous abortion (RSA) patients promote trophoblast ferroptosis and impair trophoblast cell function. Mechanistically, the CXCL2/NF‐κB/HMOX1 axis mediates this effect. Conversely, trophoblasts co‐cultured with RSA decidual macrophages induce pro‐inflammatory macrophage polarization through IL‐6/JAK2/STAT3 ...

Pubertal Development as a Marker of Gonadal Neoplasm in 46XY Complete Gonadal Dysgenesis

Journal of Pediatric and Adolescent Gynecology
46XY Complete Gonadal Dysgenesis (CGD), also known as Swyer syndrome, is characterized by nonfunctional streak gonads and an increased risk of gonadal neoplasms. While spontaneous puberty is not expected, hormonally active gonadal tumors can mimic normal puberty delaying diagnosis.We present two adolescents with 46XY CGD and tumor-driven puberty: a 16 ...

Microbiome and aging: Trajectories of microbiome age across human ecosystems and their systemic effects

iMeta, EarlyView.
Microbiome age (MA) has emerged as an innovative biomarker of biological aging, reflecting host aging trajectories through dynamic alterations in microbial composition, function, and host–microbe interactions across multiple body ecosystems. Diverse computational strategies—including traditional machine learning, deep learning, and multi‐omics ...

Complement C3 mediates adolescent social isolation‐induced hippocampal synaptic deficits and sex‐specific emotional dysfunction

Interdisciplinary Medicine, EarlyView.
Adolescent social isolation disrupts hippocampal function and exacerbates emotional symptoms, with sex‐specific patterns, as shown by human studies. In mice, social isolation decreased hippocampal synaptic density and calcium signaling, upregulated complement proteins, and activated complement‐mediated microglial synaptic phagocytosis.
