Social rank in greater long‐tailed hamsters (Tscherskia triton) shapes gut microbiota composition and metabolite profiles. Dominant males exhibit a “high‐vigilance, metabolically activated” phenotype, with elevated aggression and specific gut microbiota enriched in energy‐harvesting taxa and fecal queuine.

Chronic stress can lead to nervous system dysfunction and depression-like behaviors in animals. Gypenosides can improve chronic stress-induced neuronal damage, but the protective mechanism remains poorly understood.

Corticosterone and foraging behaviour in a pelagic seabird [PDF]
Because endocrine mechanisms are thought to mediate behavioral responses to changes in the environment, examining these mechanisms is essential for understanding how long-lived seabirds adjust their foraging decisions to contrasting environmental ...

Abstract Background and Purpose Noise pollution, particularly by aircraft, is a significant risk factor for cardiovascular disease. Aircraft noise activates stress response pathways in the brain, via the amygdala, the sympathetic nervous system and the hypothalamic–pituitary–adrenal axis.

Abstract Background and Purpose The neural mechanisms underlying effects of acute stress on memory are poorly understood. We demonstrated previously that acute stress produces identical spatial memory deficits in male and female mice but through distinct molecular mechanisms, with females exhibiting up‐regulation of N‐methyl‐D‐aspartate (NMDA) receptor

Incubation is vital for avian embryo development but demands significant parental investment, potentially at the cost of self‐maintenance and immune function. For example, the acute phase response (APR), a systemic reaction against inflammation, infection or tissue injury, can trigger sickness behaviours such as reduced activity and foraging.

Indometh acin-antihistamine combination for gastric ulceration control [PDF]
An anti-inflammatory and analgesic composition containing indomethacin and an H2 histamine receptor antagonist in an amount sufficient to reduce gastric distress caused by the indomethacin was developed.

Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

ABSTRACT Managing prolactin (PRL)‐mediated reproductive suppression is critical for maintaining egg production in commercial laying hens. L‐tyrosine (TYR), a precursor of dopamine (DA), may counteract age‐related reproductive decline by suppressing PRL, thereby sustaining productivity and egg quality in late‐phase laying hens.
