Alterations in the gut microbiota and its metabolites contribute to metabolic maladaptation in dairy cows during the development of hyperketonemia

Zhengzhong Luo, Zhenlong Du, Yixin Huang, Tao Zhou et al. • mSystems (2024)

ABSTRACTMetabolic maladaptation in dairy cows after calving can lead to long-term elevation of ketones, such as β-hydroxybutyrate (BHB), representing the condition known as hyperketonemia, which greatly influences the health and production ...

Berberine protects against hypoxia-induced intestinal injury through modulation of gut microbiota and bile acid metabolism

Hao Zhang, Hao Zhang, Hao Zhang, Penghui Ye et al. • Frontiers in Immunology (2026)

BackgroundHigh-altitude hypoxia disrupts intestinal homeostasis by impairing the epithelial barrier, triggering inflammation, and promoting microbial translocation. Berberine (BER), a natural isoquinoline alkaloid with antimicrobial and ant...
