This comprehensive volume examines the current state of free radical biology and its impact on otology, laryngology, and head and neck function. The chapters collectively highlight the interrelationship of basic and translational studies in each area, define the challenges to translation, and identify the existing basic issues that demand investigation as well as the opportunities for novel intervention to prevent and treat ENT pathology and impairment. In each chapter, or in some cases pairs of chapters, the author(s) have included or married issues of basic research with translational challenges and research, thus defining the pathway by which new basic insights may lead to interventions to prevent or treat impairment. The final chapter of this book reflects a meeting of all the contributors, culminating in a discussion and “white paper” that identifies the challenges to the field and defines the studies and collaborations that may lead to improved understanding of free radical biology in ENT and, subsequently, new interventions to medically treat ENT pathology.

There has been an explosion of research related to free radicals and antioxidants in recent years, and hundreds of laboratories worldwide are actively involved in many as pects of free radicals, oxidative stress, and antioxidants. The literature on these topics in creases exponentially every year. Over the last few years, we have been fortunate to witness a widespread recognition of the important role of free radicals in a wide variety of pathological conditions including diseases such as atherosclerosis, cardiovascular and neurological diseases, ischemia, emphysema, diabetes, radiation injury, cancer, etc. In ad dition, many laboratories are studying the role of free radicals in the inexorable process of aging. Increased evidence involves free radicals with the etiology of various diseases, thereby suggesting the use of antioxidants as a viable therapeutic approach for the treat ment of free radical mediated pathologies. Despite these impressive developments, many important aspects of free radical and antioxidant research are open for investigation. It is important to understand the overall mechanisms involved in free radical mediated physiological and pathological conditions. This knowledge will undoubtedly lead to the development of new therapeutic approaches to prevent or control free radical related diseases. This book contains the proceedings of the NATO Advanced Study Institute (ASI) on "Free Radicals, Oxidative Stress, and Antioxidants: Pathological and Physiological Sig nificance," which was held in Antalya, Turkey from May 24-June 4, 1997.

The role of reactive oxygen species and other free radicals in normal and disease processes has become a major area of interest in the medical scientific community. In the past 30 years, this area of study has advanced from outright rejection, to general acceptance, to intense study. While there is still some dispute as to the exact role of these highly reactive molecules in pathology, it is clear that they are present in and influence many biological processes. This book provides an overview of the possible biological effects of reactive oxygen species and other free radicals with an emphasis on pathology. The various types of free radicals that may affect the body are discussed along with the potential sources of free radicals, both internal and external to the body. The extensive defenses the body raises against the effects of these molecules in the form of enzymatic and non-enzymatic antioxidants is reviewed. A variety of conditions in which free radicals have been proposed to play a role are discussed. These include the physiological effects of oxygen stress in aging, exercise, and pregnancy. Pathologic conditions discussed include cancer, liver cirrhosis, respiratory problems, and others.

The role of oxidative stress in human disease has become an area of intense interest. Free radicals, a normal product of metabolism, exist in all aerobic cells in balance with biochemical antioxidants. Environmental stress increases the levels of free radicals drastically, thereby disturbing the equilibrium between free radical production and the antioxidant capability causing oxidative stress. Over the years, ROS has been implicated in the pathologies of various diseases like cancer, neurological disorder, cardiovascular diseases rheumatoid arthritis, diabetes etc. This book provides an in depth critical state-of-art reviews from established investigators on free radicals, ROS associated pathogenesis of human diseases, biomarkers of oxidative damage, antioxidants, phytonutrients and other related health concerns of modern society. The present book is aimed at graduate students, researchers in academia, industry and clinicians with the interest in redox biology. Special attention has been devoted to the topic of ROS signalling, oxidative stress induced human pathologies & antioxidative therapies. The book consists of four parts in specified topics based on the current literatures for the better understanding of the readers with respect to their subject-wise interests. The first section of the book provides an overview about the ROS production and their measuring tools and techniques followed by the mechanisms involved in the oxidative stress in the second section. The third section describes the involvement of oxidative stress in different human diseases and the last section focuses on the different strategies to ameliorate oxidative stress induced stress.

"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.

An encyclopedic summary of the highlights in the field of free radicals in medicine and biology, with a detailed analysis of the extensive recent literature. The text describes results from experimental research work on dust inhalation, hypoxia, and environmental toxicology that uses morphologic methods such as electron microscopy, interference microscopy and time-lapse technqiues in tissue cultures. The volume discusses free radical reactions that are probably involved in the pathogenesis of both physical and chemical environmental hazards. It lists radical scavengers that function as useful prophylactic agents in case of unavoidable exposure. A short history of dust diseases that have challenged mankind since prehistoric times serves as an introduction to this comprehensive treatise. It is hoped that by covering this field in one monograph, the increasingly recognized and important role of both oxygen- and nitrogen-centred radicals in disease pathogenesis will become clearer. The enclosed CD includes nearly 25.000 literature citations useful as a reference source for researchers, clinicians and students.

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."
