Our understanding of the quantitative aspects of free radical chemistry and the involvement of radicals in such areas as biology, medicine, the environment, etc., has developed spectacularly over recent years, yet the various topics are commonly discussed separately, in specific meetings and specialised publications. Free Radicals in Biology and Environment draws together two important areas of free radical chemistry, using as a bridge the fundamental physical chemistry of free radicals (spectroscopic detection of free radicals, evaluation of absolute rate constants, elucidation of mechanisms of free radical reactions and catalysis, photochemical and radiation processes, etc.). The most relevant topics covered are the EPR detection of radicals in biochemical systems and in pollutant formation and degradation, oxidation processes in biology and in the troposphere, radiation and induced damage, and atmospheric pollutants arising from incomplete combustion. Also covered are the chemistry and biochemistry of nitric oxide and peroxynitrite, the chemistry and biochemistry of DNA radicals, the role of radicals in myeloperoxidase, lignineperoxidase, radicals and cardiovascular injury, radiation and the fragmentation of cells and tissues.

In their zeal to tell the true story of sixteenth-century radicalism, some sympathizers of the Anabaptist movement have portrayed the once maligned individuals and groups as innocent, pious people who suffered cruel persecution at the hands of the wicked state-churchmen. Their side of the story is thus often as one-sided as was the story of the enemies of Anabaptism. This book, written by a Mennonite scholar, seeks to understand the reasons for the clash between Luther and the radicals, a point often neglected when one or the other side is emphasized. The study keeps Luther, however, in a central position, exploring the issues which led to the Reformer’s attitude toward the radicals and analyzing the principles that were at stake in his struggle with the dissident groups.

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.

Explore the emerging field of free radical biology, exercise, and aging with this definitive reference. Free Radicals in Exercise and Agingaddresses the current debate regarding whether free radicals released during exercise accelerate the aging process. It explains how free radicals can serve as important regulators of aerobic processes, and it clarifies the importance of exercise in increasing the efficiency of the antioxidant and oxidative repair systems. Mounting research data indicate that free radicals are involved in a variety of physiological and pathophysiological processes. This book focuses on exercise-induced adaptation. In general, a person's ability to adapt to internal and external changes decreases during the aging process. However, by continually exposing the body to different challenges, regular exercise triggers an adaptation process that keeps the body and mind fit. Free Radicals in Exercise and Agingelucidates the role of free radical species in regulating this process. This text is also one of the first to provide an in-depth review of skeletal muscle oxidative stress and aging. This issue is pivotal because muscle serves such a critical role in mobility and normal life. Free Radicals in Exercise and Aging shares the most current understanding of how reactive oxygen species influence the biology of skeletal muscles. It explores some of the unique characteristics that skeletal muscle displays during aging, both in terms of free radical production and with regard to antioxidant systems. The implications of this research are far-reaching. Mutation of DNA is linked very closely to cancer, and if regular exercise improves the regulation of the antioxidant systems and the oxidative damage repair system, these mechanisms may be a very important tool against this deadly disease. This research-oriented text presents the latest information on the subject. It reviews and critiques current literature and provides critical information for exercise physiologists, sports medicine specialists, sport nutritionists, and gerontologists.

The current volume consists of eight chapters which interweave various aspects of the structure, energetics and reactivity of organic free radicals, all combining pedagogical insights with current research. The first is by Walling in which a personalized overview is given by one of the modern pioneers of the discipline. In the next two chapters, Tsang, and Traeger and Kompe, present key thermochemical and kinetic quantities from the complementary vantage points of the studies of neutral and cationic species. The fourth chapter by Francisco and Montgomery discusses the armamentarium of modern theory as applied to species with unpaired electrons, while the next chapter by Goodman presents the theory, methodology and results from photoacoustic calorimetry, a novel and powerful experimental technique. Martinho Simoes and Minas da Piedade interrelate organometallic and free radical chemistry, while Greenberg and Liebman consider resonance energy and rearrangements as applied to small molecules and enzyme cofactors alike. The volume ends with the chapter by Tanko and Suleman, which describes the surprising and diverse solvent effects which modulate free radical chem­ istry. This volume will make it apparent to entry-level graduate students and senior researchers alike that much is known and much remains to be done in both the qualitative understanding and quantitative insights of the chemistry of organic free radicals.
