"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.

The focus of this collection of illustrated reviews is to discuss the systems biology of free radicals and anti-oxidants. Free radical induced cellular damage in a variety of tissues and organs is reviewed, with detailed discussion of molecular and cellular mechanisms. The collection is aimed at those new to the field, as well as clinicians and scientists with long standing interests in free radical biology. A feature of this collection is that the material also brings insights into various diseases where free radicals are thought to play a role. There is extensive discussion of the success and limitations of the use of antioxidants in several clinical settings.

Free radical species are generally short-lived due to their high reactivity and thus direct measurement and identification are often impossible. ESR is the only technique which has the potential for direct detection of radicals but in biological systems even these must be trapped by a spin-trapping agent. Thus most investigations involve recognition of indicators of the presence of radicals in vivo or "FOOTPRINTS" of radical-mediated damage. Techniques in Free Radical Research assembles and critically assesses the most relevant and reliable experimental approaches used towards the measurement of radicals and radical-mediated damage in chemical systems, in cells and in tissues under the following six headings: a) Footprints of DNA damage, b) Footprints of protein damage, c) Footprints of lipid peroxidation, d) Footprints of antioxidant consumption, e) Footprints via indirect radical assays, and f) Footprints via the availability of transition metal complexes.

An International Syaposiua on Free Radicals in Diagnostic Medicine was co-sponsored by the state University of New York at Buffalo, Roswell Park Cancer Institute, and the Upstate NY Section of the American Association of Clinical Chemistry. The theme was "A Systems Approach To Laboratory Technology, Clinical Correlations And Antioxidant Therapy." The symposium was held on October 7-8, 1993 at the Hyatt Hotel and on October 9 at Roswell Park Cancer Institute, Buffalo, New York. This proceedings volume contains chapters from platform presentations, poster sessions and from invited special lectures in the areas of basic science, clinical applications and efficacy of treatment. A Special Lecture on the relevance of free radical analysis to clinical medicine was presented by Professor Kunio Yagi of Japan. The Yagi procedure to measure thiobarbituric acid (TBA) reaction reflects the amount of reactive substances, lipid peroxides and aldehydes, in the sample. For example, normal subjects will have less than 4 nmol/ml of serum lipid peroxides, while a person with diabetes generally has equal or greater than 5.0 and a diabetic person with vascular complications often exceeds 7.5 nmol/ml. Serum TBA is a clinically important measure that relates to aging, gender and estrogen as an antioxidant, in the prognosis for vascular disorders, and in pathological conditions relative to the amount of lipid peroxidation. The BASIC SCIENCES portion of the program examined: "Mechanisms of Action, Pathophysiology and Laboratory Tests" in six presentations.

During the last decade, interest in the chemistry of biological systems, as well as in molecular chemical engineering, has grown considerably. Many fields in modern chemistry are contributing to a better understanding of elementary mechanisms of various biological processes and this has resulted in the development of new classes of organic and organometallic compounds with specific and high biological activity. Such a multidisciplinary approach creates opportunities for an exchange of ideas and the need to create a common language. This volume contains a collection of papers, written by leading scientists which collectively provide a rich overview of current research activities relating to the chemistry of biological systems. These papers emphasize the interdisciplinary nature of this research. For researchers in academia and industry whose work involves the chemistry and properties of biomolecular systems.

Free Radicals in Biology and Medicine has become a classic text in the field of free radical and antioxidant research. Now in its fifth edition, the book has been comprehensively rewritten and updated whilst maintaining the clarity of its predecessors. Two new chapters discuss 'in vivo' and 'dietary' antioxidants, the first emphasising the role of peroxiredoxins and integrated defence mechanisms which allow useful roles for ROS, and the second containing new information on the role of fruits, vegetables, and vitamins in health and disease. This new edition also contains expanded coverage of the mechanisms of oxidative damage to lipids, DNA, and proteins (and the repair of such damage), and the roles played by reactive species in signal transduction, cell survival, death, human reproduction, defence mechanisms of animals and plants against pathogens, and other important biological events. The methodologies available to measure reactive species and oxidative damage (and their potential pitfalls) have been fully updated, as have the topics of phagocyte ROS production, NADPH oxidase enzymes, and toxicology. There is a detailed and critical evaluation of the role of free radicals and other reactive species in human diseases, especially cancer, cardiovascular, chronic inflammatory and neurodegenerative diseases. New aspects of ageing are discussed in the context of the free radical theory of ageing. This book is recommended as a comprehensive introduction to the field for students, educators, clinicians, and researchers. It will also be an invaluable companion to all those interested in the role of free radicals in the life and biomedical sciences.
