A Review On Free Radicals and Antioxidants.
Infectious Diseases - Drug Targets, 2020Free radicals are generated in our body by several systems. A balance among free radicals and antioxidants is an important matter for appropriate physiological function. If free radicals become greater than the ability of the body to control them, a case

Toxicity of carbon tetrachloride, free radicals and role of antioxidants
Reviews on Environmental Health, 2020Several chemicals, including environmental toxicants and clinically useful drugs, cause severe cellular damage to different organs of our body through metabolic activation to highly reactive substances such as free radicals.

, 1977 A free-radical reaction is a chemical process in which molecules having unpaired electrons are involved. The radical species could be a starting compound or a product, but in organic chemistry, the most common cases are reactions that involve radicals as intermediates.

Formation of Environmentally Persistent Free Radicals on Microplastics under Light Irradiation.
Environmental Science and Technology, 2019Microplastics (MPs) are presumed to be inert during aging under ambient conditions. In this study, four types of virgin MPs, including polystyrene (PS), phenol-formaldehyde resin (PF), polyethylene (PE), and polyvinyl chloride (PVC), were aged under ...

Because of the molecular configuration, most free radicals are highly reactive and can cause cell injury. Protective mechanisms have evolved to provide defense against free-radical injury. Any time these defense systems are overwhelmed, such as during disease states, cell dysfunction may occur.

Unlike bigger and more advanced animals, Caenorhabditis elegans does not generate NO, yet it was recently found that NO produced by chemical or biological sources exerts profound effects in that animal, leading to increased life span and thermotolerance. The biological source was Bacillus subtilis, a natural food for C. elegans.

The wanderings of a free radical
Free Radical Biology and Medicine, 2009In my career I have moved from chemistry to biochemistry to plant science to clinical chemistry and back again (in a partial way) to plants. This review presents a brief history of my research achievements (ascorbate-glutathione cycle, role of iron in oxidative damage and human disease, biomarkers of free radical damage, and studies on atherosclerosis ...

Aging is the progressive accumulation of changes with time that are responsible for the ever-increasing likelihood of disease and death. These irreversible changes are attributed to the aging process. This process is now the major cause of death in the developed countries. This fact is obscured by the protean nature of the contributions of this process

Free radicals are recognized more and more frequently as being involved in the mechanism of toxicity of chemicals. In some cases, the organic radicals are involved, but often oxygen radicals result from redox cycling chemicals. Free radicals are usually very reactive, which, in addition to causing toxicities, can make them difficult to detect. Electron
