Chlorogenic acid mitigates heat stress-induced oxidative damage in bovine mammary epithelial cells by inhibiting NF-κB-mediated NLRP3 inflammasome activation via upregulating the Nrf2 signaling pathway.

Chlorogenic acid (CGA), a polyphenolic bioactive molecule derived from medicinal plants, is known for its strong antioxidant and anti-inflammatory properties. Previous studies have demonstrated that dietary supplementation with Lonicera japonica extract, rich in CGA, effectively enhances the production performance of lactating dairy cows under heat stress (HS) conditions. However, the molecular mechanisms underlying CGA's protective effects remain unclear.

Core microbe Bifidobacterium in the hindgut of calves improves the growth phenotype of young hosts by regulating microbial functions and host metabolism.

Integrated multi-omics approach and pathological analyses provide new insights into the hepatic injury and metabolic alterations in Saanen goats after dietary exposure to aflatoxin B.

Exploring the toxicity and metabolic mechanisms of Aflatoxin B (AFB) in ruminants can help to develop strategies to prevent or reduce the transfer of the toxin and its metabolites to milk and meat. This study aimed to explore the effects of 3 concentrations of dietary AFB (0, 50, and 500 μg/kg) on hepatic injury and metabolism in Saanen goats via histological examination, Western blot analysis, as well as integrated multi-omics techniques. Eighteen Saanen goats were assigned to 1 of 3 treatments and the AFB challenge lasted for 14 d.

Causal association between hypothyroidism and obstructive sleep apnea: A bidirectional 2-sample Mendelian Randomization study.

Although previous epidemiological studies have investigated the correlation between hypothyroidism and obstructive sleep apnea (OSA), the results are controversial and conflicting. Therefore, we used a bidirectional 2-sample Mendelian randomization (MR) approach to infer the causal relationship between hypothyroidism and OSA. We performed a bidirectional 2-sample MR analysis to infer the causal relationship between hypothyroidism and OSA using genome-wide association study (GWAS) data.

CircRNome-wide characterisation reveals the promoting role of circAATF in anti-PD-L1 immunotherapy of gallbladder carcinoma.
