Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Histamine and the mechanisms of nausea and vomiting: Translating the uncertain pharmacology of cyclizine

British Journal of Clinical Pharmacology, EarlyView.
Abstract Cyclizine is a long‐established, short‐acting drug, registered for preventing motion sickness, post‐operative nausea and vomiting (PONV) and ‘vomiting of known cause’. The latter is not defined but may include pregnancy and patients receiving palliative care, historically accepted without large, controlled trials.
