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 ...

Safety Assessment and Hypoglycemic Effect of Moringa oleifera Lam. Seed Lectin (WSMoL) in Alloxan‐Induced Diabetic Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT Moringa oleifera Lam. seeds contain WSMoL, a lectin previously studied for toxicity and pharmacological effects. In this study, we investigated WSMoL (10, 25, or 50 mg/kg i.p.) for acute and 14‐day repeated‐dose toxicity, as well as genotoxicity, in Swiss mice.
