Named after Selene, Greek goddess of the moon, selenium (Se) has moved has moved from being thought of as a toxicant to being considered an essential nutrient with the potential to reduce cancer risk in the span of seven decades. Diversity of Selenium Functions in Health and Disease focuses on current knowledge of aspects of Se research relevant to its medical use, and particularly to chemoprevention of cancer. It covers how Se is integrated into selenoproteins, selenium compounds with individual functions and dual functions, and unexpected links to Se such as with diabetes. The text ends with a discussion of polymorphisms and mutations in genes of selenoproteins. The chapters elucidate why studies undertaken to prevent diseases with selenium ended with disappointing outcomes and often with the opposite result, i.e. disease promotion. They show that benefit, failure, or side effects depend on: The chemical form and dose of selenium The selenium status of the individual ingesting selenium The capacity of selenium form to serve as a source for selenoprotein biosynthesis The function of selenoproteins reacting to a change in the selenium status The stage of the disease (mainly cancer) at the time point of intervention The genetic background of individuals to be treated Bringing together the accumulated evidence regarding selenium biochemistry, the book covers aspects not found in available general monographs. The narrow focus on medical uses of Se helps resolve the present confusion about potential benefits and hazards of selenium in human health. The book gives you a solid scientific basis for optimum use of selenium in preventing or treating human diseases and answering the questions: Why is selenium essential? How much is required? What are the health consequences of low selenium and can selenium reduce cancer risk?
Since biological tissues are unstable in an oxygen atmosphere, a great deal of effort is expended by organisms to metabolically limit or repair oxidative tissue damage. This volume of Methods in Enzymology and its companion Volume 233 present methods developed to investigate the roles of oxygen radicals and antioxidants in disease. It includes techniques and assays of the activity of biothiols in soluble systems, their interaction with lipids and proteins, and the various new thiol enzymes, such as thioltransferases, being elucidated. Antioxidant reactions and gene regulation are also included.
Micronutrients and Brain Health addresses cutting-edge research related to processes of oxidative stress that affect brain function, an area of increasing significance for those concerned and involved with public health and translational medicine. Edited by four leading micronutrient researchers, the book brings together the investigative work of more than 70 leading researchers from across the world. Chapters identify brain-specific micronutrients that support function as well as the molecular mechanisms underlying their neuroprotectant activity. These explore age-related metabolic pathways, mitochondrial nutrients, neurodegeneration and micronutrients, cell signaling, and neuronal functions. General chapters are included on brain structure, function, and metabolism, while several other chapters are devoted to the role of specific micronutrients. The book explores how brain micronutrients are found to be both metabolic and redox regulators, thereby establishing a cross-talk between the major pathways involved in modulation of cell signaling and gene expression. Specific areas of research covered include: Uses of nutritional interventions to target age-related neuronal and behavioral deficits Effects of various micronutrients on Alzheimer's disease, including lipoic acid, green tea, and Ginkgo biloba extracts Nutrients specific to essential mitochondrial functions Cognitive and behavioral consequences of iron deficiency with specific emphasis on women of reproductive age Omega-3 fatty acids and their relation to brain function in the elderly Challenges inherent in the development of neuroprotective-neurorescue drugs This book belongs to the groundbreaking CRC Press Series on Oxidative Stress and Disease. The series now includes more than two dozen volumes that address increasing evidence regarding the multiple ways that oxidative stress initiates and accelerates disease mechanisms. Most importantly, this book, like the series, offers invaluable information regarding nutritional and lifestyle choices, and pharmaceutical interventions that can be employed to prevent, control, and even ameliorate disease processes attributed to oxidative stress.

Characterized by obesity, insulin resistance, dyslipidemia, and hypertension, metabolic syndrome is associated with the risks of type 2 diabetes mellitus and cardiovascular disease. Obesity, which increases the incidence of atherosclerotic cardiovascular disease and subsequently leads to increased stress and inflammation, appears to play a central role in the progression of the syndrome. Evidence of inflammatory processes in accumulated fat appears to be an early initiator of metabolic syndrome. Likewise, the more active angiotensin system in obesity may contribute to even greater oxidative stress that serves as a key signaling event in vascular remodeling. These factors strengthen obesity's association with oxidative stress. Oxidative Stress and Inflammatory Mechanisms in Obesity, Diabetes, and the Metabolic Syndrome is designed to encourage the development of evidence-based nutritional and pharmacological therapies that can attenuate the impact of obesity-induced insulin resistance and ensuing metabolic syndrome. The book offers a deep understanding of the molecular mechanisms that underlie the process. Edited by leading authorities on oxidative stress, the book's chapters report on cutting-edge research that explores intracellular events mediating or preventing oxidative stress and pro-inflammatory processes in obesity and type 2 diabetes. It also brings together research on the molecular mechanisms inherent in the progression of metabolic stress, includes phenotypic perspectives, and discusses dietary factors, including the role of micronutrients. The chapter authors, each a leading expert in his or her field, discuss different components of metabolic stress and obesity and their associations with oxidative stress and inflammation. The book fills a unique role as a base of knowledge for researchers seeking to develop nutritional and or pharmacological therapies, as well as clinicians seeking a better understanding of this increasingly common dis

Understanding the molecular basis of complex biological processes has been a major goal of biological chemistry from early on. Inflammation is one such entity, and recent years have seen exciting progress in the under- standing of molecular interactions; there has been a long way from dolor, rubor, calor, and tumor as a fundamental description of the phenomenon to current knowledge, e.g., on the control of the respiratory burst of the granulocyte, the atomic details of protease regulation, or the interaction of cytokines. We were glad to have been given the opportunity by the Gesellschaft fUr Biologische Chemie to call upon experts in this bustling field of research for this Colloquium. The sessions were organized in the order of increasing complexity, starting with the key phenomena of the inflamma- tory response and its modulation by cytokines to intravascular events and shock and sepsis; thus, the current attempts to apply basic knowledge on mediators of inflammation to the clinical situation were also considered. In-depth chapters presenting the state of the art in these areas are collected in this book, and we thank the authors for their efforts. We also thank the Chairmen of the sessions, Profs. C. Sorg (Munster), D. Roos (Amsterdam), S. Bhakdi (Mainz), H. J. Muller-Eberhard (Hamburg), H. G. Schwick (Marburg), K. Resch (Hannover), W. Schaper (Bad Nauheim), D. Keppler (Heidelberg), and O. Trentz (Zurich) for their input, and it is a great pleasure to acknowledge the support by Drs.
Hepatic cells are involved in the metabolization and elimination of a variety of endogenous and exogenous substances. They mediate the uptake, processing and subsequent secretion of biliary compounds, such as various drugs or hormones, and the passage of metabolites to be released into different blood compartments. To perform vectorial passages hepatocytes show a strong polarity with sites for endocytotic processes or specific carrier molecules, and a specified system of organelles for intracellular transport and sorting, metabolization and secretion of compounds. Several aspects, e.g. regulation, control and mechanisms of hepatic traffic are reported in detail - complemented by methodological approaches to analyse and monitor these processes.
Peroxisomes (microbodies) have a long evolutionary lifespan, but in cell biology they are still young. It is gratifying to see that most recent advances in our knowledge of peroxisomes come from quite different disciplines, ranging from molecular biology and cell biology to clinical research. The identification in terms of cDNA sequences of enzymes, the localization in terms of immuno-electron microscopy, and the cell biological aspects of the organelle biogenesis have seen substantial progress very recently. Likewise, the phenomenon of peroxisome proliferation induced by a number of drugs, e. g. hypolipidemics and plasticizers, constitute an active area of research, where much is still to be learnt. The medical problem of inborn errors of metabolism seems to have gained a new realm for discovery. Here, the advances in knowledge within the last year have been particularly striking. Therefore, the "International Symposium on Peroxisomes in Biology and Medicine", held in Heidelberg from July 14-17,1986, was even more excit- ing than could have initially been anticipated. The present volume consists of papers from that conference. For sake of rapid publication, the camera- ready format, inspite of all its drawbacks (e. g. no proof reading by authors), was chosen. It is our pleasure to acknowledge support and help. The Symposium was supported by Deutsche Forschungsgemeinschaft, Bonn, by the Ministerium ftir Wissenschaft und Kunst Baden-Wtirttemberg, Stuttgart, as well as by a number of generous contributors from industry.
Vitamin C, or ascorbic acid, has a long and multifaceted scientific history. In 1937, the Nobel Prize for Physiology and Medicine was awarded to Albert Szent-Gyorgyi'in recognition of his discoveries concerning the biological oxida tion processes with special reference to vitamin C', and the Nobel Prize for Chemistry was shared by Sir Norman W. Haworth, who was the first to synthesize the vitamin. Vitamin C is a potent antioxidant, and this action represented the theoretical basis for various lines of investigation on this molecule in which the potential role of ascorbic acid in the prevention and treatment of a series of dis eases, whose pathogenesis is linked to an excess of free radicals such as athero sclerosis and cancer, have been examined. These data have been analyzed in detail by experts in biochemistry, epidemi ology, and preventive and clinical medicine in the International Symposium Vitamin C, the state of the art in disease prevention sixty years after the Nobel Prize, held in Monte Carlo from October 31 to November 1, 1997, under the aus pices and the scientific endorsement of the Nutrition Foundation of Italy and with the financial support of Bracco SpA and Merck."
