Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

Animal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.

Versatile Nanodrugs Containing Glutathione and Heme Oxygenase 1 Inhibitors Enable Suppression of Antioxidant Defense System in a Two‐Pronged Manner for Enhanced Photodynamic Therapy

Advanced Healthcare Materials, 2021
The antioxidant defense system in malignant cells, which involves antioxidant enzymes and antioxidant molecules, is an innate barrier to photodynamic therapy (PDT). Because of the complexity of the endogenous antioxidant mechanisms of these cells, simply

Antioxidant defense systems in newborns undergoing phototherapy

The Indian Journal of Pediatrics, 1999
This paper was designed to investigate whether phototherapy is an oxidative stress in newborn infants undergoing phototherapy. A day-light continuous phototherapy was given to jaundiced 20 term and 16 preterm newborns for 72 hours. We measured serum vitamin E and the activities of red blood cell anti-oxidation enzymes (superoxide dismutase, catalase ...

Free radicals, antioxidant defense systems, and schizophrenia

Progress in Neuro-Psychopharmacology and Biological Psychiatry, 2013
The etiopathogenic mechanisms of schizophrenia are to date unknown, although several hypotheses have been suggested. Accumulating evidence suggests that excessive free radical production or oxidative stress may be involved in the pathophysiology of schizophrenia as evidenced by increased production of reactive oxygen or decreased antioxidant protection

Regulation of antioxidant defense and glyoxalase systems in cyanobacteria

Plant Physiology and Biochemistry, 2021
Oxidative stress is common consequence of abiotic stress in plants as well as cyanobacteria caused by generation of reactive oxygen species (ROS), an inevitable product of respiration and photosynthetic electron transport. ROS act as signalling molecule at low concentration however, when its production exceeds the endurance capacity of antioxidative ...
