Book Description
Free Radicals in Biology, Volume 1, provides an introduction to some of the basic concepts of free radical biology. The book emerged from the President's Symposium of the American Society for Experimental Pathology held in Atlantic City in April 1970. The book's opening chapter introduces a mechanistic view of free radical reactions using examples from biological systems. This is followed by a discussion of autoxidative damage to lipids in membranes. Some of the special chemistry of lipid oxidation are presented, and a number of novel ideas are suggested. The third chapter deals with the uses of electron-spin resonance in biology. Spin labeling is also discussed, which is one of the most useful methods of probing the chemical and physical environment of molecules in cells. The remaining chapters cover free radicals which occur in photosynthesis and the importance of the enzyme, superoxide dismutase. The study of the occurrence and reactions of this enzyme provides an important and extensive body of data clearly pointing to the significance of free radicals in cellular chemistry.

Book Description
Biological Oxidation Systems, Volume I is a collection of papers presented at the 1989 Bangalore Symposium on Oxygen Systems. This symposium covers various research studies on the essential roles, and the dangers of dioxygen reactions in biology. This volume is organized into five parts encompassing 32 chapters, and starts with an overview of the biological oxidation mechanisms involving oxygen and reduced oxygen derivatives. Parts I and II deal with the catalytic role of cytochrome P-450 and oxidase and oxygenase containing a flavin or pteridine enzymes in several biological oxidation reactions. These parts examine the biochemical aspects, reaction kinetics, and reaction mechanisms of such reactions. Parts III and IV describe first the structure function and properties of copper-containing oxidases and oxygenases. These parts also discuss the role of nonheme iron-containing and other oxygenases in the indole metabolism. Part V focuses on the role of peroxidase enzymes in cell protection and metabolism. This book will prove useful to biologists, enzyme scientists, and researchers.

Book Description
Crack Your Code and Reach a New Level of Healing and Health Doctors traditionally prescribe a pill for every ill. But for most people, these single solutions don't work. The truth is, most chronic health problems, including stubborn weight gain, unbeatable fatigue, intestinal distress, high blood pressure, creeping cholesterol, and high blood sugar, are not found in simply one organ, but in several parts of the body (oftentimes in twos and threes). This is the result of years of slow, subtle challenges to your metabolism, which is as unique as you are. Your diet, lifestyle habits, stress level, prescription drug use, and relationships, as well as the genes you inherit and the environment in which you live-in effect, the sum total of your life experience up to this day-determine your personal metabolism and, in turn, your current state of health. Using a step-by-step, easy-to-implement system of diet, lifestyle strategies, and state-of-the-art nutrients and supplements, Dr. James LaValle will help you create an individualized program for reclaiming your metabolism and health......At long last, this book provides readers with the information and tools that have been used successfully by thousands of Dr. LaValle's patients over the last twenty years to help them take charge of their diets, their health, and their lives.

Book Description
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.

Book Description
Free Radicals in Biology, Volume III reviews diverse topics in free radical biology and relates the results of chemical and biochemical investigations to clinical situations. It attempts to bridge the gap between chemical investigations and the medical applications and implications of free radical reactions. Topics covered range from radiation chemistry to biochemistry, biology, and medicine. Comprised of seven chapters, this volume begins with a general introduction to the technique of radiation chemistry; the thermodynamics and kinetic factors that need be considered; the use of pulse radiolysis and flow techniques; and the application of these methods to free radicals of biological interest. The reader is then introduced to the pulse radiolysis method and the mechanisms of carbon tetrachloride toxicity. Subsequent chapters discuss the morphological, histochemical, biochemical, and chemical nature of lipofuscin pigments; production of free radicals from the reactions of selected enzymes with their substrates; and the damage caused to skin by sunlight. The final chapter deals with the involvement of free radicals in chemical carcinogenesis. This monograph will be of value to chemists, biologists, and physicians.

Book Description
Free-radical reactions have been for long time the domain of the physical chemists and the basic chemical industry (polymerization of vinyl monomers, oxidation by molecular oxygen, chlorination of methane etc.), where the use of simple molecules and the possibility of partial conversions without heavy problems of product separations makes less dramatic the aspects of regio and chemoselectivity. As synonym of unselectivity, free radical reactions were considered of poor use in the synthesis of fine chemicals or sophisticated molecules, where a high selectivity is an essential condition for the success, or in the involvement of biological processes. Within the last 15 years, however, an authentic explosion of synthetic applications of free radical reactions occurred; they have gained a remarkable position among the selective methods of synthesis. At the same time the great importance of free radical reactions in fundamental biological processes and in the metabolism of drugs has been recognized. Thus a specialized meeting on these topics was generally felt appropriate. I had the honour and the onus to organize this workshop because for more than 30 years I have been involved in the research of free radical reactions. Thanks to a generous grant from NATO Scientific Affairs Division and the financial support of CNR and chemical industry (Montedison, Enichem, Zambon) such a meeting among almost 50 specialists and 15 observers of sufficient standard to take advantage of the discussion, became possible at Bardolino (Italy).

Book Description
This book is the outcome of an international conference, held at the Aviya Sonesta Hotel in Eilat, Israel, on March 24-27, 1985. This was the 30th in a series of the annual OHOLO Conferences, sponsored by the Israel Institute for Biological Research. Participants in this Conference consisted of scientists from four teen countries; represented a broad spectrum of research interests; and included a well-balanced representation from academia, clinical institutions and pharmaceutical industry. The book includes talks, poster sessions, and a comprehensive general discussion, all from the proceedings of this conference. In the interest of assuring a rapid publication of the novel infor mation reviewed, this book has been prepared in camera-ready format. We are cognizant of the fact that several typographical errors may exist in the text, and that there are variations in style and typeface of the var ious chapters. This, we felt, was a reasonable compromise for the sake of speed and efficient transmission of valuable scientific information. No body is perfect . •••• The success of the conference, and hence the quality of this book are attributable to the extensive efforts of a large number of extremely capable individuals. These include members of the Scientific Organizing Committee, and the Technical staff of the OHOLO Organization. Of course, the conference could not have succeeded without the high quality of the presentations, and the enthusiastic participation of the contributing scientists.

Book Description
Elementary radical reactions are described in terms of fundamental knowledge of organic chemistry and chemical physics in this valuable reference text. The complex radical processes of nonchain and chain mechanisms, such as dimerization, alkylation, polymerization, telomerization, halogenation pyrolysis, oxidation and combustion, are complemented by reactions in chemical lasers and in the cosmos, as well as by reactions in biological objects under normal or pathological metabolism. The text also provides the synthesis of facts from various fields of research and involves mechanisms where free radicals appear either as main or side intermediates in one of the several alternatives of the reaction pathway. Highlights include 38 tables and 39 figures.
