Correlation Between Gut Microbiota, Metabolites, and Diabetic Complications: A Two‐Sample Mendelian Randomization Study

Medicine Advances, EarlyView.
Fang et al. demonstrate a significant causal relationship among gut microbiota, gut metabolites, and diabetic complications, highlighting a biological link underlying mechanisms of diabetic vascular diseases. These findings provide important implications for future therapeutic strategy and risk prediction.

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development

PROTEOMICS, EarlyView.
ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.

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.

A dynamic meiotic SUN belt includes the zygotene-stage telomere bouquet and is disrupted in chromosome segregation mutants of maize (Zea mays L.).

Frontiers in Plant Science, 2014
The nuclear envelope (NE) plays an essential role in meiotic telomere behavior and links the cytoplasm and nucleoplasm during homologous chromosome pairing and recombination in many eukaryotic species.

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.
