Two near‐complete assemblies reveal R‐subgenome structural and centromeric divergence associated with reproductive isolation in hexaploid triticale

iMeta, EarlyView.
We present two near‐complete triticale genome assemblies and perform pan‐centromere analyses across >200 haplotypes from parental species, synthetic allopolyploids, cultivars, and 337 resequenced accessions, revealing a shared chromatin framework underlying functional centromeres in all three subgenomes, where wheat‐ and rye‐derived CENH3 co‐occupy ...

The Role of High Cxcl11 Expression in Ovarian Dysfunction Through NF‐κB and AKT Pathways in a Thin Endometrium Mouse Model

iNew Medicine, EarlyView.
Thin endometrium upregulates Cxcl11, which polarizes ovarian macrophages via NF‐κB/AKT, impairing ovarian function. A new uter‐ovarian signaling axis is identified. ABSTRACT Objective Thin endometrium (TE) is a recognized cause of female infertility, primarily associated with impaired uterine receptivity.

Toxic Effects of Bisphenol A and Its Analogs on Ovarian Structure and Function: A Narrative Review of Ovary‐Focused Studies

Journal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA) is a widely used industrial chemical found in polycarbonate plastics and epoxy resins and is recognized for its endocrine‐disrupting properties. Human exposure is common due to its presence in food packaging and everyday products. As BPA use has been restricted, structurally similar compounds such as BPS, BPB, BPAF, and BADGE

Mapping Causal Biology: Mendelian Randomization in the Era of Big Data

Med Research, EarlyView.
Mendelian randomization (MR) leverages genetic variants to mitigate confounding biases in causal inference. This review systematically maps MR's methodological evolution, highlights its expanding applications in epidemiology and drug target validation, and outlines future directions for overcoming current biases through dynamic, multi‐omics, and cross ...

Reproductive Challenges of the Ageing Female: A Comprehensive Narrative Review

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Changes in societal norms over the last few decades have resulted in novel family planning trends, notably delayed childbearing and increased maternal age at the birth of the first child. Despite advances in reproductive medicine, ageing poses significant challenges.
