Journal ArticleDOI
Free radicals and antioxidants in normal physiological functions and human disease
TL;DR: Attention is focussed on the ROS/RNS-linked pathogenesis of cancer, cardiovascular disease, atherosclerosis, hypertension, ischemia/reperfusion injury, diabetes mellitus, neurodegenerative diseases, rheumatoid arthritis, and ageing.
Journal ArticleDOI
Free Radicals in the Physiological Control of Cell Function
TL;DR: There is growing evidence that aging involves, in addition, progressive changes in free radical-mediated regulatory processes that result in altered gene expression.
Journal ArticleDOI
Toxic Potential of Materials at the Nanolevel
TL;DR: The establishment of principles and test procedures to ensure safe manufacture and use of nanomaterials in the marketplace is urgently required and achievable.
Journal ArticleDOI
Reactive oxygen species and antioxidant machinery in abiotic stress tolerance in crop plants
TL;DR: The biochemistry of ROS and their production sites, and ROS scavenging antioxidant defense machinery are described, which protects plants against oxidative stress damages.
Journal ArticleDOI
Oxidants, antioxidants, and the degenerative diseases of aging
TL;DR: It is argued that this damage to DNA, protein, and lipid is a major contributor to aging and to degenerative diseases of aging such as cancer, cardiovascular disease, immune-system decline, brain dysfunction, and cataracts.
