This book summarizes recent advances in understanding the mechanism underlying the selective cell death of dopamine neurons in Parkinson's disease. MPTP, endogenous neurotoxins, L-DOPA, and metal were proved to induce apoptosis and necrosis in neurons. The relationship of these causal factors to the pathogenesis of Parkinson's disease was discussed to give us overviews on the role of neurotoxins in this degenerative disorder. This title further presents the intracellular signal transduction, and the related enzymes and other factors involved in dopaminergic neuronal death. Recent results on intracellular mechanism of neuroprotection are presented, suggesting that neuroprotection as a causal therapy of neurodegenerative disorders may become practical in near future. This book shows new neuroprotective agents, such as propargylamine derivatives and neurotrophins, and the intracellular mechanism to prevent the activation of apoptotic cascade in neurons. The authors of this book are active researchers participating in these subjects and the readers will find the knowledge and techniques for the study on neurotoxicity and neuroprotection, and the strategy for future research on these important subjects in clinical and basic neurology and neurosciences. The book is dedicated to Professor Toshiharu Nagatsu, a pioneer in the search for pathogenic factors in Parkinson's disease. The book is reprinted from the journal 'Neurotoxicology and Teratology', Volume 24/5.

Behavioral toxicology is a young discipline in the United States; so young, in fact, that this is one of its first books. Behavioral questions are bound to play a major role in future scientific work and governmental decisions involving the health effects of environmental contaminants and other chemicals. This role springs from two key problems that face scientists and public agencies required to set acceptable exposure standards or to determine criteria for the toxicity of therapeutic chemicals: How do you evaluate effects that may show up only as subtle functional disturbances? And how do you de tect toxic effects early enough so that they may still be reversible, before they produce major damage? The contributions in this book come from a collection of scientists whose interests span a wide variety of problem areas. The focus is largely on me thodological issues because they represent the most immediate concern of the discipline. We expect that this collection of papers will represent a useful source book for behavioral toxicology for some time. For the past few years, the University of Rochester's Department of Radiation Biology and Biophysics has sponsored a series of international conferences on chemical toxicity, partly as a response to concern over the con sequences to health of the rich chemical soup in which we live. This book is based upon presentations made to the fifth of the series. Held in June, 1972, it was the first formal meeting devoted to behavioral toxicology in this country.

This multidisciplinary book includes current research papers and reviews in the areas of basic neuroscience, neural mechanisms underlying neurodegenerative disorders. It further includes new approaches for neuroprotective treatments, clinical, neurobiological and treatment aspects of psychiatric disorders. The book was conceived as a celebration of the professional life and work of Peter Riederer to mark the occasion of his retirement.

Serotonin (5-hydroxytryptamine, often cited as 5-HT) is one of the major excitatory neurotransmitters, and the serotonergic system is one of the best studied and understood transmitter systems. It is crucially involved in the organization of virtually all behaviours and in the regulation of emotion and mood, and pathological alterations in the serotonergic system underlie behaviour and psychiatric conditions (among a host of very successful drugs targeting the serotoninergic system are Prozac and Zoloft). This is the first truly integrated handbook providing a broad overview over the many face

Chemistry, Biochemistry, and Biology of 1-3 Beta Glucans and Related Polysaccharides presents a comprehensive, systematic and authoritative survey of information about a family of chemically related, but functionally diverse, naturally occurring polysaccharides--the (1-3)-glucans. International contributors describe the chemical and physicochemical properties of these glucans and their derivatives and the molecular biological and structural aspects of the enzymes involved in their formation and breakdown. A detailed analysis of their physiological roles in the various biological situations in which they are found will be provided. Additionally, evolutionary relationships among the family of these glucans will be described. - Topics of medical relevance include detailing the glucans' interactions with the immune system and research for cancer therapy applications - Web resource links allow scientists to explore additional beta glucan research - Separate indexes divided into Species and Subject for enhanced searchability
