Arginase 2 deficiency mitigates sepsis‐associated acute kidney injury by alleviating lipid accumulation

Clinical and Translational Medicine, Volume 16, Issue 9, September 2026.
1. Spatiotemporal multi‐omics atlas reveals regional metabolic and proteomic specificity during sepsis‐to‐S‐AKI progression. 2. Arginine metabolism is central to S‐AKI pathogenesis, with declining arginine levels correlating with worsening renal function. 3. ARG2 upregulation in renal tubules and macrophages drives tubular lipid accumulation and kidney

Testicular toll with viral intrusion: Molecular insights into the impact of chronic HIV infection on male fertility

Clinical and Translational Medicine, Volume 16, Issue 9, September 2026.
The molecular mechanisms contributing to impaired fertility in HIV+ males remain poorly defined. Using a human immunodeficiency virus (HIV) transgenic (Tg) rat model, we demonstrate key structural and functional sperm regulators including cation channel of sperm (CatSper)1–4 channels and mitochondrial biogenesis genes were markedly downregulated ...

Genetic Diversity of Agronomic Traits and Identification of Genes Regulating Thousand‐Grain Weight in Foxtail Millet (Setaria italica) Germplasm Resources

Food and Energy Security, Volume 15, Issue 5, September/October 2026.
ABSTRACT Thousand‐grain weight (TGW) is a critical determinant of grain yield in foxtail millet. To elucidate the molecular regulatory network governing this trait, we systematically evaluated the main agronomic traits and genetic diversity of 40 core germplasm accessions, aiming to identify elite genetic resources.

Impact of Inoculation Strategy on Dendrobium nobile Lindl. Rice Wine Quality Through the Use of Saccharomyces cerevisiae FBKL2.8022 and Wickerhamomyces anomalus FBKL2.8023

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
This graphical abstract compares four fermentation strategies for D. nobile rice wine: simultaneous inoculation without D. nobile (SW), simultaneous inoculation with D. nobile (DnSW), sequential inoculation without D. nobile (WS), and sequential inoculation with D. nobile (DnWS). Simultaneous inoculation (SW/DnSW) enhanced volatile compound content (up
