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

PROTEOMICS, Volume 26, Issue 7, Page 42-56, July 2026.
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.

Global Fluoride Toxicology Landscape: Bibliometric Approaches and Scientific Mapping

Environmental Toxicology, Volume 41, Issue 7, Page 416-458, July 2026.
ABSTRACT This study analyzed research trends in the 100 most‐cited articles on fluoride toxicology, a topic widely debated due to the toxic effects associated with levels deemed safe for human exposure. A bibliometric analysis was conducted using the Web of Science‐Core Collection, extracting data such as citation count, authors, keywords, journal ...

Trade‐offs between surviving and thriving: A careful balance of physiological limitations and reproductive effort under thermal stress

Functional Ecology, Volume 40, Issue 7, Page 1994-2010, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Balancing survival and reproduction presents a fundamental evolutionary challenge, especially in extreme and unpredictable environments. Thermoregulatory behaviour, in particular, imposes a costly trade‐off, as time spent maintaining optimal body temperature precludes ...

Age‐Associated Senescence of Decidual Macrophages: A Key Mediator of Adverse Pregnancy Outcomes in Advanced Maternal Age

Aging Cell, Volume 25, Issue 7, July 2026.
Decidual macrophages (DM) in advanced maternal age (AMA) exhibit FOXO3 deficiency‐driven senescence, further accelerated by elevated uterine IL‐6. This manifests as pro‐inflammatory polarization, increased senescence markers, reduced phagocytosis, and impaired trophoblast function.
