The Role of Protein and Amino Acids in Sustaining and Enhancing Performance


Book Description

It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.




Metabolism of the Nervous System


Book Description

Metabolism of the Nervous System contains the proceedings of the 2nd International Neurochemical Symposium, held at Aarhus, Denmark, in July 1956. The book discusses the molecular structure and morphology of the adult nervous tissue; the chemical composition and cytochemical localization of adult nervous tissue; and the permeability and blood-brain barrier. The text also describes topics on electrolytes and nervous conduction; the metabolism of isolated nerve and ganglion; and the metabolism of the brain in vivo. The metabolism of brain tissue preparations in vitro; energy metabolism and coenzymes in relation to the nervous system; and lipid and fatty acid metabolism are also considered. The book further tackles nucleic acid metabolism; protein and amino acid metabolism; and cholinergic and non-cholinergic transmission. The text also discusses other pharmacologically active compounds related to the adult nervous tissue.

Protein Metabolism of the Nervous System


Book Description

Few can deny the paramount importance of the neurosciences, undoubtedly one of the most challenging fields in contemporary science. Recent years have witnessed the awakening of interest in brain research by many dis tinguished investigators from other branches of science, which has made possible the multidisciplinary approach needed for the complex problems of this field. The present book, which deals with one aspect of this research, is the result of the symposium held under the auspices of the New York State Research Institute for Neurochemistry and Drug Addiction in April 1968. It has become clear that brain proteins are involved in all aspects of mental function and dysfunction, and the present volume documents the latest advances in our knowledge (advances made to a large extent by con tributors to this volume). The chapters not only convey some of the enthu siasm and wonderful, cooperative spirit of the many excellent scientists ex ploring the brain, and their wealth of ideas; they also illustrate the many approaches from which cerebral proteins can be studied in a meaningful manner. In some areas even preliminary evidence is worth discussing: e.g., it is an exciting achievement that we can begin to apply the disciplines of bio chemistry to phenomena of learned behavior and information handling.




Cellular Organelles


Book Description

The purpose of this volume is to provide a synopsis of present knowledge of the structure, organisation, and function of cellular organelles with an emphasis on the examination of important but unsolved problems, and the directions in which molecular and cell biology are moving. Though designed primarily to meet the needs of the first-year medical student, particularly in schools where the traditional curriculum has been partly or wholly replaced by a multi-disciplinary core curriculum, the mass of information made available here should prove useful to students of biochemistry, physiology, biology, bioengineering, dentistry, and nursing.It is not yet possible to give a complete account of the relations between the organelles of two compartments and of the mechanisms by which some degree of order is maintained in the cell as a whole. However, a new breed of scientists, known as molecular cell biologists, have already contributed in some measure to our understanding of several biological phenomena notably interorganelle communication. Take, for example, intracellular membrane transport: it can now be expressed in terms of the sorting, targeting, and transport of protein from the endoplasmic reticulum to another compartment. This volume contains the first ten chapters on the subject of organelles. The remaining four are in Volume 3, to which sections on organelle disorders and the extracellular matrix have been added.




Biochemistry of Characterised Neurons


Book Description

Biochemistry of Characterised Neurons provides a report on the progress made in the analysis of the biology of specific neurons in the central nervous system. This book emphasizes the biochemical, morphological, and functional aspects of characterized neurons, including ways and sophisticated techniques of isolating them. This publication is divided into 11 chapters. The first chapter evaluates the relevance of working with single neurons. Chapters 2 to 6 discuss specific, characterized, invertebrate neurons containing one of the putative neurotransmitter substances. Chapter 7 deals with the biochemistry of a unique vertebrate (Torpedo) cholinergic system that enables pure cholinergic neuronal cell bodies and endings to be analyzed separately. The sensitive radiochemical procedures used to analyze transmitter substances and transmitter enzymes, and how they can be adapted to map the distribution of transmitters in individual neurons of Aplysia, are discussed in Chapter 8. Chapter 9 describes methods for the analysis of specific cells in the retina, while Chapters 10 and 11 focus on the analysis of proteins within defined neurons. This text is beneficial to biochemists and students interested in analyzing neurons.

Glutamate-Related Biomarkers in Drug Development for Disorders of the Nervous System


Book Description

Glutamate is the most pervasive neurotransmitter in the central nervous system (CNS). Despite this fact, no validated biological markers, or biomarkers, currently exist for measuring glutamate pathology in CNS disorders or injuries. Glutamate dysfunction has been associated with an extensive range of nervous system diseases and disorders. Problems with how the neurotransmitter glutamate functions in the brain have been linked to a wide variety of disorders, including schizophrenia, Alzheimer's, substance abuse, and traumatic brain injury. These conditions are widespread, affecting a large portion of the United States population, and remain difficult to treat. Efforts to understand, treat, and prevent glutamate-related disorders can be aided by the identification of valid biomarkers. The Institute of Medicine's Forum on Neuroscience and Nervous System Disorders held a workshop on June 21-22, 2010, to explore ways to accelerate the development, validation, and implementation of such biomarkers. Glutamate-Related Biomarkers in Drug Development for Disorders of the Nervous System: Workshop Summary investigates promising current and emerging technologies, and outlines strategies to procure resources and tools to advance drug development for associated nervous system disorders. Moreover, this report highlights presentations by expert panelists, and the open panel discussions that occurred during the workshop.
