Download or read book Analysis of Free Radicals in Biological Systems written by A. Favier and published by Birkhäuser. This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Oxidative stress" is used as the generic term describing the involve ment of reactive oxygen species in various human diseases. The scope of such a topic is becoming increasingly wide. The recent interest in radicals such as nitric oxide and the discovery of new mechanisms such as the effect of free radicals on redox sensitive proteins and genes are enlarging our understanding of the physiological role of free radicals. Oxidative stress is involved in numerous pathological. processes such as ageing, respiratory or cardiovascular diseases, cancer, neurological pathologies such as dementia or Parkinson's disease. It still remains difficult, however, to demonstrate by chemical measurement the in vivo production of free radicals and even more to realise their speciation. Therefore, the development of new tools and indicators is engrossing many researchers working in this field. Reliable indicators are abso lutely necessary not only to monitor the evolution of oxidative stress in patients but also to evaluate the efficiency of new antioxidant treat ments. The French Free radical club of Grenoble, the CERLIB has been involved for many years in the organisation of international training programs on methodology, in order to provide both theoretical and practical help to researchers from various countries. Such training sessions have been highly successful and participants value the oppor tunity to learn reliable techniques. This positive echo explains why the researchers of CERLIB decided, with the help of Prof. Dr. B. Kalyanaraman, to publish selected techniques on free radical re search.
Download or read book Oxygen Radicals in Biology and Medicine written by Michael Simic and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 1064 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the papers presented at the "Fourth International Congress on Oxygen Radicals (4-ICOR)," held June 27 - July 3, 1987, at the University of California, La Jolla. The chapters deal with the phenomena associated with highly reactive oxygen species (hydroxy, peroxy, alkoxy, aroxy, and superoxide radicals, as well as singlet oxygen) and their peroxidation products (hydrogen peroxide, hydroperoxides, peroxides, and epoxides) as they relate to the fields of chemistry, food technology, nutrition, biology, pharmacology, and medicine. The kinetics, energetics, and mechanistic aspects of the reactions of these species and the interrelationship of oxygen radicals (or any other free radicals) and peroxidized products have been emphasized. Special attention is focused on the mechanisms of the generation of free radicals and peroxy products in biosystems and on the adverse effects of these radicals and products in humans. The topics span the continuum from the simple chemistry of model systems to the complex considerations of clinical medicine. The book also explores the mechanisms of agents that protect against free radicals and peroxy products in vitro and in vivo. These agents include antioxidants used in materials, food antioxidants, physiological antioxidants, and antioxienzymes (SOD, glutathione peroxidase, and catalases). The use of these inhibitors to prevent damage to organs being prepared for transplantation, thereby maintaining the quality of transplanted organs and/or extending their "shelf-life," also is examined.

Download or read book Free Radicals in Biology and Medicine written by Barry Halliwell and published by OUP Oxford. This book was released on 2015-08-21 with total page 896 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free Radicals in Biology and Medicine has become a classic text in the field of free radical and antioxidant research. Now in its fifth edition, the book has been comprehensively rewritten and updated whilst maintaining the clarity of its predecessors. Two new chapters discuss 'in vivo' and 'dietary' antioxidants, the first emphasising the role of peroxiredoxins and integrated defence mechanisms which allow useful roles for ROS, and the second containing new information on the role of fruits, vegetables, and vitamins in health and disease. This new edition also contains expanded coverage of the mechanisms of oxidative damage to lipids, DNA, and proteins (and the repair of such damage), and the roles played by reactive species in signal transduction, cell survival, death, human reproduction, defence mechanisms of animals and plants against pathogens, and other important biological events. The methodologies available to measure reactive species and oxidative damage (and their potential pitfalls) have been fully updated, as have the topics of phagocyte ROS production, NADPH oxidase enzymes, and toxicology. There is a detailed and critical evaluation of the role of free radicals and other reactive species in human diseases, especially cancer, cardiovascular, chronic inflammatory and neurodegenerative diseases. New aspects of ageing are discussed in the context of the free radical theory of ageing. This book is recommended as a comprehensive introduction to the field for students, educators, clinicians, and researchers. It will also be an invaluable companion to all those interested in the role of free radicals in the life and biomedical sciences.

Download or read book Free Radicals in Biology V1 written by William Pryor and published by Elsevier. This book was released on 2012-12-02 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free Radicals in Biology, Volume 1, provides an introduction to some of the basic concepts of free radical biology. The book emerged from the President's Symposium of the American Society for Experimental Pathology held in Atlantic City in April 1970. The book's opening chapter introduces a mechanistic view of free radical reactions using examples from biological systems. This is followed by a discussion of autoxidative damage to lipids in membranes. Some of the special chemistry of lipid oxidation are presented, and a number of novel ideas are suggested. The third chapter deals with the uses of electron-spin resonance in biology. Spin labeling is also discussed, which is one of the most useful methods of probing the chemical and physical environment of molecules in cells. The remaining chapters cover free radicals which occur in photosynthesis and the importance of the enzyme, superoxide dismutase. The study of the occurrence and reactions of this enzyme provides an important and extensive body of data clearly pointing to the significance of free radicals in cellular chemistry.
Download or read book Autoxidation in Food and Biological Systems written by M.G. Simic and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: The material presented in this book deals with basic mechanisms of free radical reactions in autoxidation processes and anitoxidant suppression of autoxidation of foods, biochemical models and biologi cal systems. Autoxidation in foods and corresponding biological effects are usually approached separately although recent mechanistic developments in the biochemistry and free radical chemistry of per oxides and their precursors tend to bring these two fields closer. Apparent ability of antioxidants in diets to reduce the inci dence of cancer has resulted in scrutiny of autoxidized products and their precursors as possibly toxic, mutagenic and carcinogenic agents. Mechanisms of any of these effects have been barely ad dressed. Yet we know now that free radicals, as esoteric as they were only a few decades ago, are being discovered in foods, biochem ical and biological systems and do play a role in the above-mentioned causalities. The purpose of the Workshop and the resulting book was to give a unifying approach towards study of beneficial and deleterious effects of autoxidation, based on rigorous scientific considerations. It is our hope that the material presented in this book will not only provide a review of the "state of the art" of autoxidation and anti oxidants, but also reflect the interaction which occurred during the Workshop between workers using model sytems, and food and biological systems.
