Oxidative stress is the state of a diminished capacity of a biological system to counteract an overproduction or invasion of reactive oxygen species and other radicals. This book presents recent advancements in the understanding of oxidative stress, the mechanisms of damage to cells and biomolecules, and pathological implications in disorders including Alzheimer’s disease, Parkinson’s Disease, cardiovascular disease, cell damage in HIV-AIDS, stroke, autism and premature aging. The book is a comprehensive source of information describing new directions in diagnostics of oxidative stress, including novel detection methods of oxidative-stress biomarkers, prevention by antioxidants, and therapy using novel free radical scavenging agents and natural defense systems
