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.

Radicals for Life: the Various Forms of Nitric Oxide provides an up-to-date overview of the role of nitrosocompounds and nitrosyl-iron complexes in physiology. Nitrosocompounds can be considered as stabilised forms of nitric oxide, one of the most important regulatory molecules in physiology today. Many nitrosocompounds share some of the physiological functions of nitric oxide, and may be formed inside living organisms. This is the first book to be published that is dedicated to the role of such nitrosocompounds in physiology, with particular emphasis on the nitrosocompounds that are endogenously formed in higher organisms and humans. Points of discussion include: physical and chemical properties of the compounds, the main chemical pathways in vivo, as well as the physiological effects that have been recognised to date. Each of the nineteen chapters is written by distinguished specialists in the field, well known for their original and important contributions to the subject. Also included are results from a wide range of studies in vitro, in cell cultures, animal models and human volunteers. Examples of alternative forms of nitric oxide, with special emphasis on their protective role against widespread human diseases like atherosclerosis, Alzheimer's disease, diabetes, sexual dysfunction, and renal insufficiency to stroke and ischemia are also included. - First monograph to consider and provide an overview of endogenous nitrosocompounds and nitrosyl-iron complexes - Extensive bibliographic references, written by specialists of human physiology - Providing high scientific quality with a focus on implications for human diseases

Free radical-mediated reactions have been well known in chemistry and physical chemistry for many years. Applying this knowledge to living organisms, biochemists have shown that reactive free radicals are formed at many intracellular sites during normal metabolism, and they have started to suggest possible roles in various pathological processes and conditions, for example in radiation damage, in the metabolism of xenobiotics, in carcinogenesis and in metabolic disorders. At present, a large and relevant mass of experimental evidence supports the view that reactive free radicals are involved in the pathogenesis of several diseases and syndromes. This literature has captured the attention and interest of people involved in the biomedical field. Exciting developments in radical research are probable in the near future, establishing a greater interaction between basic science research and medicine. While the task of defining the involvement of free radicals in human pathology is difficult, it is nonetheless extremely important that such interaction be fulfilled as soon as possible. These were the considerations motivating us during the organization of the VI Biennial Meeting of the International Society for Free Radical Research held in Torino, Italy, in June 1992, and also during the preparation of this book. Experts in the various aspects of free radical research were invited to participate in the Torino Meeting and to contribute chapters for this volume.
