Available in PDF, EPUB and Kindle. Book excerpt: "The Biochemical View of Antioxidants presents research on medicinal plants and organic chemistry and relates to pharmacological applications. This book discusses antioxidants, derived from fruits and vegetables, which play a vital role in maintaining health. It forms a bridge between biology and chemistry of fruits and vegetables by studying the complex nature of antioxidants. The Biochemical View of Antioxidants consists of 45 chapters. The chapters show that food constitutes a source of many biologically active antioxidants important for health and disease prevention. The antioxidant properties of fruits and vegetables have to do with the presence of tissues with natural antioxidant compounds that protect plants from free radical damage caused by oxygen in the environment or exposure to ultraviolet radiation. According to nutritionists, the most valuable source of antioxidants are fresh fruit and vegetables and natural preparations made from them, such as juices, preserves, marmalades, jams and silage"--

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: In our first protocols book, Free Radical and Antioxidant Protocols (1), r- erence to in vivo, ex vivo, or in situ techniques were few compared to classical biochemical assays and only 6 of the 40 chapters were concerned with these applications. In our second book, Oxidative Stress Biomarkers and Antioxidant Protocols (2), which is being published concurrently with this third volume, Oxidants and Antioxidants: Ultrastructure and Molecular Biology Protocols, the number of such chapters has increased. The literature dealing with histoche- cal/cytochemical and immunohistochemical techniques and staining to identify cellular/subcellular sites of oxidative stress has expanded rapidly, as has the molecular biology methodology used to analyze free radical and antioxidant (AOX) reactions, as well as the monitoring of living tissue. A two-way search was performed for each technique listed in Table 1, coupled with “oxidative stress” using the PUBMED search engine from the National Library of Medicine at NIH. Most of the techniques involved in m- suring oxidative stress employ molecular biology or ultrastructural approaches. Of these techniques, histology, polymerase chain reaction, and Western blotting are the most widely used. Several forms of therapy are now available for patients with increased oxidative stress. In addition to standard antioxidant therapy supplementation in vivo and in vitro, photodynamic therapy (PDT) employs excitation of a photon-emitting compound delivered systemically for free radical-mediated necrosis of affected tissues, and stem cells are also being used to induce signaling events or replace antioxidant enzymes.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The use of antioxidants is widespread throughout the rubber, plastics, food, oil and pharmaceutical industries. This book brings together information generated from research in quite separate fields of biochemical science and technology, and integrates it on a basis of the common mechanisms of peroxidation and antioxidant action. It applies present knowledge of antioxidants to our understanding of their role in preventing and treating common diseases, including cardiovascular disease, cancer, rheumatoid arthritis, ischemia, pancreatitis, hemochromatosis, kwashiorkor, disorders of prematurity and disease of old age. Antioxidants deactivate certain harmful effects of free radicals in the human body due to biological peroxidation, and thus prevent protection against cell damage. The book is of considerable interest to scientists working in the materials and foodstuff industries, and to researchers seeking information on the connection between diet and health, and to those developing new drugs to combat diseases associated with oxidative stress. It is important also throughout the non-medical world, especially to the work force within the affected industries.

This book was released on 2012-12-06 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty years ago, the enzyme superoxide dismutase which uses the superoxide radical anion as its specific substrate was reported. With this discovery was born a new scientific field, in which oxygen, necessary for aerobi c 1 ife on thi s planet, had to be cons i dered also in terms of its toxicity and stresses. This stimulated the search for knowledge of active oxygen species in biology and medicine. Superoxide and other reactive oxygen species are now implicated in many disease processes. Major advances have been achieved during these past years with respect to free radical generation and mechanisms of free radical action in causing tissue injury. In parallel, the possibil ity of influencing free radical related disease processes by antioxidant treatment was studied in various in vitro and in vivo systems. This was the unique theme of a conference organized in Paris by the Society for Free Radical Research (December 9-10, 1988) which brought together experts from basic sciences and clinicians in order to evaluate the current status of antioxidant therapy. The conference emphasized fundamental processes in antioxidant action. Among the major topics were superoxide dismutase (SOD) and low molecular weight substances with such activity, called SOD mimics. Other antioxidant enzymes were also considered. Antioxidant vitamins, in particular vitamins E and C, other naturally occurri ng antioxidants and vari ous synthet i c antioxidants were included in the presentations as there is now a rapidly developing series of compounds with potentially interesting clinical applications.
