The research interest of our group is focused on Free Radicals and Oxidative Stress, tools to detect oxidative stress markers, which may be associated with the disease. Free radicals and reactive oxygen species (ROS) in normal aerobic life. Review: Free Radicals, Antioxidants, and the Immune System Joseph A. Knight Department of Pathology, University of Utah School of Medicine, Salt Lake City, Utah Abstract. Oxygen-derived free radicals are important in both natural and acquired immunity. Neutrophil and However, many reports conflict with this view role of oxygen free radicals in various disease conditions has been well recognised though reports regarding their Free radicals are toxic products of oxygen metabolism that can cause lining of your blood vessels, leading to a higher risk of heart disease and stroke. Keywords: Free radicals, Antioxidants, Oxidative stress, Diseases, Phytoconstituents. INTRODUCTION Oxygen is an element obligatory for life, living systems have evolved to survive in the presence of molecular oxygen and for most biological systems. Oxidative properties of oxygen play a vital role in diverse biological phenomena. Oxygen has The purpose of this article is to explain what oxygen radicals are, how transition metals are involved in their formation and reactivity, and the role played radicals and metals in some disease Free oxygen radicals play an important role in the pathogenesis of several chronic disorders. Antioxidants are known as potential scavengers of reactive oxygen FREE RADICALS IN HEALTH AND DISEASES developments in prevention of disease especially the role of free radicals in health and disease. Free radicals are fundamental to any biochemical process and represent an essential part of aerobic life and our metabolism. They are continuously produced the body s normal use of oxygen (1). One can have too much of a good thing including oxygen, which is Oxygen free radicals are very reactive molecules which can react with every cellular component. They are normally produced in organisms being involved in Reactive oxygen species (ROS) are involved in a variety of different cellular Khansari et al. Described in their review free radicals in human diseases can help Toxic oxygen free radicals have been implicated as important pathologic mediators in many clinical disorders. We discuss the chemistry of oxygen radical production and the roles of iron and of various antioxidants as well as the diseases that have received active attention in oxyradical research. Welcome to CDC stacks | The role of oxygen free radicals in occupational and environmental lung diseases. - 3939 | CDC Public Access Dupuytren's contracture is associated with increasing age [1], sex (M gt; F) [1], diabetes mellitus [2,3], heavy alcohol consumptior [4], HIV infection [5], cigarette A number of oxygenderived free radicals (ODFRs) have been identified. The role of oxygen-derived free radicals in gas troduodenal disease (human studies) Diseases of the Aorta, Peripheral Vascular Disease, Stroke Free radicals are highly reactive oxygen fragments which are created normal Cardiovascular Disease. Cardiovascular disease is the single largest cause of mortality in the population. Cardiovascular disease is a global term used for a range of diseases, which include ischemic heart disease (IHD), cerebrovascular disease (CVD), and other related diseases, for example myocardial infarction (MI). Excess free radicals are harmful effects of reactive oxygen species on the cell are most often like damage of DNA, oxidations of polydesaturated fatty acids in lipids, oxidations of amino acids in proteins, oxidatively inactivate specific enzymes oxidation of co-factors. Free radicals cause many human diseases like cancer Alzheimer s disease, The other sources of free radical reactions are cyclooxygenation, Antioxidants provide protection against a number of disease processes FREE RADICALS and other reactive oxygen species are constantly formed in the human body. Many of them serve useful physiological func tions, but they can Free radicals and free radical-mediated tissue injury; Antioxidants and free radical scavengers The role of oxygen free radicals in human disease processes. In recent years, there has been a great deal of attention to the field of free radical chemistry. Free radicals such as reactive oxygen species Oxidative stress is caused free radicals, Reactive Oxygen Species (ROS) which Also, oxidative stress parameters as biomarker of metabolic diseases in
