Book Description
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.

Book Description
Oxygen free radicals and other reactive oxygen species are being postulated as causal agents in an increasing number of pathological conditions. Indeed, some investigators are suggesting that highly destructive reactive oxygen species are the final common path lead ing to tissue damage following a wide variety of insults including trauma, hypoxia, ischemia, hyperoxia, radiation, some toxins, and even strenuous athletic pursuits. But, as Robert Floyd points out, "Proof of the importance of oxygen free radicals and the oxidative damage they initiate depend on unequivocal evidence for the pres ence of free radicals and a clear association of their formation with the induction of the dysfunction of pathological conditions. " Since such proof does not come easily, there have been and will continue to be many controversies regarding the role played by reactive oxygen species in tissue damage. There have been many recent reviews of the chemistry and pos sible role of reactive oxygen species in many types of organ dys functions, tissue damage, degenerative diseases, and aging. This book is not such a review. Rather it presents for a diverse audience of physical-organic chemists, biochemists, medical researchers, and other investigators of pathophysiology, discussions of a variety of is sues important for understanding reactive oxygen species and their role in tissue damage.

Book Description
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.

Book Description
Gastrointestinal Tissue: Oxidative Stress and Dietary Antioxidants brings together leading experts from world renowned institutions, combining the basic mechanisms of gastrointestinal diseases with information regarding new and alternative treatments. The processes within the science of oxidative stress are described in concert with other processes, including apoptosis, cell signaling and receptor mediated responses, further recognizing that diseases are often multifactorial with oxidative stress as a component. By combining the critical molecular processes underlying free radical mediated pathologies and the role of dietary antioxidant molecules, a connection is made that helps advance therapies and the prevention of gastrointestinal pathological processes. This important reference is well designed with two complementary sections. Section One, Oxidative Stress and Gastroenterology, covers the basic processes of oxidative stress from molecular biology to whole organs, the gastrointestinal anatomy and sources of oxidative stress and free radicals and their products in gastrointestinal diseases. Section Two, Antioxidants and Gastroenterology covers antioxidants in foods, including plants and components. - Covers the science of oxidative stress in gastrointestinal tissue and associated conditions and scenarios - Provides information on optimal levels for human consumption of antioxidants, suggested requirements per day, recommended dietary allowances and curative/preventive effects of dietary antioxidants - Presents an easy to reference guide with two complementary sections that discuss the pathophysiology of gastrointestinal diseases in relation to oxidative stress and antioxidant therapies

Book Description
Over two centuries ago, oxygen was discovered as "air vital": the component of the earth's atmosphere necessary for life. Less than five years after this discovery, it was found that oxygen was both a life-sustaining and life threatening inhalant as it plays a role in the two extremes of the animal kingdom: life and death. In the subse quent years, we have made major strides in understanding the role of oxygen in maintaining life and volumes of information are now available on this topic. Our knowledge of the contribution of oxygen in cellular dysfunction and cell death which for the most part had lagged behind has begun to catch up. The deleterious ef fects of oxygen radicals and activated oxygen species on a variety of biological systems have now been described. Recently attention has also been focused on the toxic effects of oxygen on the cardiovascular system. The major aim of the present treatise is to offer an integrated view of the pathophysiological aspects of oxygen toxicity in the heart and blood vessels coupled with a review of therapeutic approaches (hopes?) with free radical scavengers and antioxidants. Internationally known expert investigators provide a concise and critical review on the topic of their expertise which also contains data from their own research.
