This book contains the proceedings of the ARW NATO Conference on "Action of Free Radicals and Active Forms of Oxygen on Lipoproteins and Membrane Lipids: Cellular Interactions and Atherogenesis", held in Bendor, France, October 5-8,1988. Since the pioneer work of Mc Cord and Fridovitch, growing interest has been focused on the study of the role of oxyradicals role in pathology. This interest is reflected in the exponential increase in the number of papers on free radicals, the success of specialized journals and books on this theme, and the organization of national and international meetings. These meetings have discussed, from.a broad point of view, the problems concerning the mechanisms of production of free radicals, their effects on cell CO!1$tituants (lipids, proteins, nucleic acids) and cell function, the methods of analysis of these phenomena, the pathological states in which free radicals may be involved, natural biological defense systems, and the design of "antiradical" therapies. But it is now well established that the most common target of oxy free radicals are membrane lipids because of their chemical nature (cholesterol in saturation, malonic linkage of polyunsaturated fatty acids (PUFA» and of their regular structural arrangement (monolayers in lipoproteins, bilayers in cell membranes). Thus the analysis of the products resulting from the action of oxy free radicals on PUFA is considered the best tool to indirectly evaluate the effects of tissue peroxidations, although the analytical basis for doing so is very questionable.

Diabetes: Oxidative Stress and Dietary Antioxidants, Second Edition, builds on the success of the first edition, covering updated research on the science of oxidative stress in diabetes and the potentially therapeutic usage of natural antioxidants in the diet and food matrix. The processes within the science of oxidative stress are not described in isolation, but rather in concert with other processes, such as apoptosis, cell signaling and receptor mediated responses. This approach recognizes that diseases are often multifactorial and oxidative stress is a single component of this. Since the publication of the first edition, the science of oxidative stress and free radical biology continues to rapidly advance with thousands of the research articles on the topic. New sections in this update cover the role of dietary advanced glycation end products (AGEs) in causing OS in diabetes, oxidative stress and diabetes-induced bone metabolism, and oxidative stress and diabetic foot ulcer. - Saves clinicians and researchers time in quickly accessing the very latest details on a broad range of diabetes and oxidation issues - Combines the science of oxidative stress and the putative therapeutic usage of natural antioxidants in the diet, its food matrix or plant - Includes preclinical, clinical and population studies to help endocrinologists, diabetologists, nutritionists, dieticians and clinicians map out key areas for research and further clinical recommendations

Antioxidants inhibit the formation and spread of free radicals which can be damaging in biological systems. Free radicals form in biological systems through metabolism, but it is also realized that exogenous environmental sources, such as radiation, food, and drugs, contribute significantly to the generation of free radicals in biological systems. Being reactive species, free radicals are short-lived and do not travel far from cellular targets. Their concentration in biological systems is very low and is difficult to detect directly by electron spin resonance spectroscopy (ESR). Indirect methods of reactions of radicals with specific biomolecules are also sufficiently sensitive to detect quantitatively their presence. Thus the response of antioxidant defenses which react with radical species, can serve as an indirect measure that free radicals have been formed. Redox-based antioxidants change their oxidation state and antioxidants become free radicals themselves. Often, however, the antioxidants give rise to more persistent free radicals, sometimes owing to delocalization of the lone electron around ring structures (in vitamin E, ubiquinones, and certain carotenes). Persistent free radicals react only rarely and the precursors often can be regenerated in biological systems. In recent years, it is becoming clearer from biochemical studies on how the major lipophilic antioxidants work. Particular attention has been given to vitamin E and quinones found in animal and plant membranes and in carotenoids, for the protection of membranes in lipoprotein systems. Flavonoids form another rich and varied source of natural antioxidants.

Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.

Lipid oxidation, though researched since the beginning of the 20th century, still gives no complete and satisfactory information on the composition of oxidized lipids. One important factor contributing to these gaps in our knowledge about lipid oxidation relates to the shortages in analytical methodology. Analytical methods suitable for oxidized lipids were often reviewed in the last decade, but mostly from the aspect of determination of individual oxidized lipid classes, such as peroxides, aldehydes, polar lipids, or polymers. In this book, they are treated from the standpoint of types of analytical methods used, including different volumetric methods, UV-visible spectrometric methods, high performance size-exclusion chromatography, nuclear magnetic resonance spectroscopy, electron spin resonance spectroscopy, and differential scanning calorimetry. Analysis of Lipid Oxidation is essential for further developments in analytical methodology and hyphenated techniques, with which more understanding of the reaction kinetics, mechanism, and implications will take place.
