Free radical theory of ageing MCQs With Answer — This focused review introduces B. Pharm students to the free radical theory of ageing, explaining how reactive oxygen species (ROS) and oxidative stress drive cellular senescence via mitochondrial dysfunction, lipid peroxidation, protein oxidation and DNA damage. Key biochemical pathways, such as Fenton and Haber–Weiss reactions, enzymatic … Read more
Introduction Free radicals play a central role in brain metabolism and are key mediators of oxidative stress that contribute to kidney and muscle damage. Reactive oxygen species (ROS) and reactive nitrogen species (RNS) arise from mitochondria, NADPH oxidase, xanthine oxidase and drug metabolism, causing lipid peroxidation, protein oxidation, DNA damage and mitochondrial dysfunction. Antioxidant defenses—glutathione, … Read more
Free radicals and reactive oxygen species (ROS) play central roles in the pathogenesis of cancer and atherosclerosis. Oxidative stress from excess ROS/RNS causes DNA damage, lipid peroxidation, protein oxidation, endothelial dysfunction, and chronic inflammation, driving carcinogenesis and plaque formation. Key concepts for B. Pharm students include sources of ROS (mitochondria, NADPH oxidase, xanthine oxidase), biomarkers … Read more
Role of free radicals in Ischemic reperfusion injury MCQs With Answer — Introduction Ischemia-reperfusion injury (I/R) occurs when blood flow returns to ischemic tissue, triggering an intense surge of free radicals and reactive oxygen species (ROS). Key sources include mitochondria, xanthine oxidase, NADPH oxidase and activated neutrophils that generate superoxide, hydrogen peroxide and hydroxyl radicals. … Read more
