Download or read book Handbook Methods For Oxygen Radical Research written by Robert A. Greenwald and published by CRC Press. This book was released on 2018-02-01 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is divided into five sections. Section I deals with preparative methodology for isolation and purification of the components of the oxy radical experimental systems use most frequently, including all three forms of SOD and several other important scavengers. Section II provides the experimenter with a choice of a dozen oxy radical generating systems which can be used for testing of scavengers or for evaluation of the effects of oxy radicals on target tissues. The reader will note that in this section, as well as in most of the rest of the volume, the orientation is primarily biochemical, biologic, and medical, rather than pure chemistry or pure physics. Nevertheless, the techniques are widely applicable to a variety of disciplines.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The rapid expansion of the area of free radical biology in the last 25 years has occurred within a framework of assumptions and preconceived notions that has at times directed the course of this movement. The most dominant of these notions has been the view that free radical production is without exception a bad thing, and that the more efficient our elimination of these toxic substances, the better off we will be. The very important observation by Bernard Babior and colleagues in 1973 that activated phagocytes produce superoxide in order to kill micro organisms, served to illustrate that constructive roles are possible for free radicals. For many in the field, however, this merely underscored the deadly nature of oxygen-derived radicals, both from the microbe's point of view and from the host's as well. (Phagocyte-produced superoxide is responsible in part for the tissue injury manifested as inflammation. See Harris and Granger, Chapter 5, and Leff, Hybertson and Repine, Chapter 6.) Mother Nature, however, has a penchant for being able to make a silk purse from a sow's ear. If one is dealt a bad hand, one must simply make the best of it. After two decades of focusing on the destructive side of free radicals, the last few years have begun to reveal a new and finer perspective on free radical metabolism - a role in regulation of cellular function (see Schulze-Osthoff and Baeuerle, Chapter 2). Evidence from a number of sources suggests that an increase in the oxidative status of cell encourages that cell to grow and divide. Increasing the expression of mangnese superoxide dismutase can suppress the malignant phenotype of melanon cells (see Oberley and Oberley, Chapter 3). Oxidative stress beyond a certain poitosis (from the Greek, literally "to fall apart"). Is this suicide response an evolutionary fail-safe device to curtail tumorogenesis? Does oxidative stress-induced apoptosis account for the loss of immune cells in AIDS (see Flores and McCor Chapter 4)? This volume attempts to present the spectrum of roles, both good and bad played by active oxygen species as understood at this point in the evolution of this field of free radical biology.
Download or read book Free Radicals in Biology V5 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 V covers the mechanisms for the generation of free radicals. This volume contains eight chapters that discuss the biology and chemistry of oxy-radicals in mitochondria and the radical-mediated metabolism of xenobiotics. The opening chapter describes the mechanisms of free radical production in enzymatically promoted lipid peroxidation, generally in microsomes or microsomal lipids. The subsequent chapters explore the biochemistry and biology of plant and animal lipoxygenases; the production of superoxide and hydrogen peroxide in mitochondria; and the biological role of these species in mitochondria and related systems. The discussions then shift to the effects of superoxide production in white blood cells, with an emphasis on an evaluation of the oxygen-dependent reactions of the important phagocytic cells, the monocytes, and the polymorphonuclear leukocytes. This volume further covers the formation and the role of oxy-radicals in the red blood cell, which is a very useful system for studying the protection of biological tissue against radical-mediated damage. A chapter presents a comprehensive review of the production of free radicals during the metabolism of xenobiotics. The last chapters provide an overview of the enzymology, biological functions, and free radical chemistry of glutathione peroxidase. These chapters also examine a number of gerontological principles and the effect of antioxidants in aging. Chemists, biologists, and physicists will find this book of great value.

Download or read book Reactive Oxygen Species in Chemistry Biology and Medicine written by A. Quintanilha and published by Springer. This book was released on 1988-04 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: A NATO Advanced Study Institute on "Oxygen Radicals in Biological Systems: Recent Progress and New Methods of Study" was held in Braga, Portugal between Sep tember 1 and September 14, 1985, in order to consider the basic chemistry and biochem istry of activated oxygen (both radical and non-radical species) and their effect in biolog ical systems. This book summarizes the main lectures given at this meeting. While there is no attempt to cover all the major topics in the expanding subject of oxidative mechanisms in biology, an effort has been made to provide overviews on some key aspects of this field. The authors have attempted to convey a clear picture of both what is known and what remains unclear in their respective subjects. Not only are some of the techniques used for detecting activated oxygen species described, but also their strengths and limi tations. The chemistry of many of these species is discussed and the biological and/or pathological implications are carefully reviewed. The medical and therapeutic aspects of some of the well established pathways of damage and protection are analyzed. It is our hope that the material included in this book might be useful for both researchers and teachers at the graduate level. The success of this meeting was to a large extent due to the tireless committment of Professor Alberto Amaral and Dr. Concei~a:o Rangel; without their outstanding efforts in dealing with all the aspects of the organization, this summer school would not have been possible.
