This 2010 review by Kunlin Jin provides a comprehensive overview of current biological theories explaining the aging process, categorizing them into two broad groups: programmed theories and damage (or error) theories. Programmed theories suggest that aging is regulated by genetically controlled processes, including hormonal changes, immune decline, and epigenetic modifications.
This study examined the effects of vitamins C and E on human lens epithelial cells (HLEC) that had been depleted of glutathione (GSH) and subjected to oxidative stress from hydrogen peroxide (H₂O₂). The findings demonstrated that supplementation with these antioxidants significantly reduced oxidative damage, including protein oxidation, lipid peroxidation, and
This article reviews the role of antioxidants in neurodegenerative diseases like Alzheimer’s and Parkinson’s, focusing on how oxidative stress contributes to disease progression and exploring the potential therapeutic benefits of antioxidants. The study discusses evidence from animal models and human trials, indicating that antioxidants, such as vitamin E and Coenzyme
