Ghrelin, the endogenous ligand for the growth hormone secretagogue (GHS) receptor, is critical in the control of food intake and energy balance. The ghrelin receptors are now known to have important physiological properties as modulators of growth hormone release, appetite, glucose homeostasis, metabolism, immune function, neurotransmitter activity, cognitive function and neurodegeneration. Bringing all of this information together in the first comprehensive text on the topic, Ghrelin in Health and Disease provides a state-of-the-art synthesis of the latest work in this area for physicians and physician-scientists. This volume addresses the unique property of ghrelin as a modulator of function. Such a property provides potential utility for safe intervention in a wide variety of disease states. Indeed as we learn more about the basic physiology of ghrelin, the potential for treating new disease targets emerge requiring validation in the clinic. Each chapter in this volume is authored by a leading investigator in the field. The introductory chapter sets the background for the book and provides a superb overview of the relevance of ghrelin to physiology, describing how the discovery of ghrelin has prompted us to completely rethink traditional physiology. The authors conclude their chapters by critically addressing the future translational aspects of ghrelin biology and outlining what key basic research and clinical questions remain to be addressed. An invaluable resource, Ghrelin in Health and Disease distinguishes itself as the first comprehensive title covering all of the molecular and clinical issues relating to ghrelin and advancing our clinical understanding of obesity, growth, and reproductive pathogenesis.

This book discusses the architecture, functioning, and biomechanics of the human body, its bones, joints, muscles, tendons, and ligaments. The book explains energy extraction from food and drink, what efforts the body is capable of, and how our efforts depend on the coordination among the respiratory, circulatory, and metabolic systems. This text shows how the body monitors itself, how it reacts to work loads and the environment such as heat or cold, humidity and wind. The book also explains how to measure a person's ability to work at high efficiency: by observation of breathing rate, heart beat frequency, oxygen consumption, and by careful evaluation of subjective judgements.The text discusses, in practical terms, effects of environmental conditions and how shift work arrangements during day, evening, and night affect task performance.

Since the publication of the first edition of this book ten years ago, international research into the physiological ecology of plants in the tropics has increased enormously in quantity and quality. This brand new edition brings the story right up to date. New approaches have been developed in remote sensing while at the other end of the scale molecular biology has come on in leaps and bounds, particularly regarding ecological performance of tropical plants, e.g. in understanding the adaptation of resurrection plants to the extreme habitat of inselbergs. In this fully revised and updated second edition the wealth of new information has made it necessary to break large chapters down into smaller ones.

This insightful and comprehensive book covers nearly every aspect of glutamate receptor structure and function for the working researcher and student. It condenses two previous landmark volumes into one easily accessible volume, and covers the extraordinary research and significant developments in the decade since the previous books were published. This includes the central role glutamate receptors play in neurotransmission.

The obesity epidemic has generated immense interest in recent years due to the wide-ranging and significant adverse health and economic consequences that surround the problem. Much attention has been focused on behaviors that lead to obesity, in particular to over consumption of energy-dense food and to sedentary lifestyle. However, obesity is an extremely complex condition with poorly defined pathogenesis. Thanks to greatly enhanced research in the area, the discovery of pathways in the brain and peripheral organs that mediate energy homeostasis has provided a framework for understanding the biological basis of obesity. Metabolic Basis of Obesity adds an important new dimension to the growing literature on obesity by offering a comprehensive review of specifically how metabolic imbalance culminates in obesity. Developed by a team of expert authors, this important title discusses the principles of energy balance, genetics of body weight regulation, hormones and adipokines, and metabolic pathways in the brain, liver, muscle and fat, to name just several of the areas covered. The book also examines the connection between obesity and diabetes, cardiovascular disease and other complications. Current and future diagnostic and treatment strategies are also reviewed. Comprehensive and timely, Metabolic Basis of Obesity is an essential reference for understanding the burgeoning problem of obesity.

Hopefully, this book will be taken off of the shelf frequently to be studied carefully over many years. More than 40 researchers were involved in this project, which examines respiration, circulation, and metabolism from ?sh to the land vertebrates, including human beings. A breathable and stable atmosphere ?rst appeared about 500 million years ago. Oxygen levels are not stable in aquatic environments and exclusively water-breathing ?sh must still cope with the ever-changing levels of O 2 and with large temperature changes. This is re?ected in their sophisticated count- current systems, with high O extraction and internal and external O receptors. 2 2 The conquest for the terrestrial environment took place in the late Devonian period (355-359 million years ago), and recent discoveries portray the gradual transitional evolution of land vertebrates.

Recently, physiology has expanded into related ?elds such as biochemistry, molecular biology, morphology and anatomy. In the light of the work in these ?elds, the introduction of DNA-based cladograms, which can be used to evaluate the likelihood of land vertebrates and lung?sh as a sister group, could explain why their cardio-respiratory control systems are similar. The diffusing capacity of a duck lung is 40 times higher than that of a toad or lung?sh. Certainly, some animals have evolved to rich high-performance levels.

The scientific advances in the physiology and pathophysiology of adipose tissue over the last two decades have been considerable. Today, the cellular and molecular mechanisms of adipogenesis are well known. In addition, adipose tissue is now recognized as a real endocrine organ that produces hormones such as the leptin acting to regulate food intake and energy balance in the central nervous system, a finding that has completely revolutionized the paradigm of energy homeostasis. Other adipokines have now been described and these molecules are taking on increasing importance in physiology and pathophysiology. Moreover, numerous works have shown that in obesity, but also in cases of lipodystophy, adipose tissue was the site of a local low-grade inflammation that involves immune cells such as macrophages and certain populations of lymphocytes. This new information is an important step in the pathophysiology of both obesity and related metabolic and cardiovascular complications. Finally, it is a unique and original work focusing on adipose tissue, covering biology and pathology by investigating aspects of molecular and cellular biology, general, metabolic, genetic and genomic biochemistry.

The period between 1950 and 1980 were the golden unique insights into how pathological processes affect years of transmission electron microscopy and produced cell organization. a plethora of new information on the structure of cells This information is vital to current work in which that was coupled to and followed by biochemical and the emphasis is on integrating approaches from functional studies. TEM was king and each micrograph proteomics, molecular biology, genetics, genomics, of a new object produced new information that led to molecular imaging and physiology and pathology to novel insights on cell and tissue organization and their understand cell functions and derangements in disease. functions.

As the title suggests, and unlike other existing books on sleep medicine, Neuroendocrine Correlates of Sleep/Wakefulness will be devoted primarily to endocrine regulation of the behavioral state control. It will address a wide spectrum of sleep./wakefulness phenomena (both animals and humans), including pathogenesis, diagnosis, and management. From molecular biology to applied clinical therapy, sleep research has been transformed in the last few years from a research backwater to an important interdisciplinary field. Anyone who regularly reads the literature on sleep, biological rhythms, or neuroendocrinology is aware that one of the subspecialties within sleep medicine, the neuroendocrine correlates of sleep/wakefulness, has in particular experienced a growth rate that is even faster than that of the field as a whole. To a significant extent this has been due to the introduction of new research technologies. The widespread adoption of a range of new methods in sleep research has opened a window into activities at the cellular and molecular level, which previously had been tightly closed. Consequently these activities are being characterized with a degree of precision and sensitivity that is without precedent. This volume invites the reader to explore the new vistas that have been opened onto the neuroendocrine frontier of sleep medicine. The editors have selectively identified a number of key articles having a citation frequency, which is considerably above the norm or which otherwise have contributed importantly to defining the neuroendocrine perspective. This new volume on Neuroendocrine Correlates of Sleep/Wakefulness is an up-to-date resource of research summaries and reviews written by major contributors to the fields of sleep, biological rhythms and neuroendocrinology. Its coverage is broad and its basic and clinical science reviews are detailed. In this volume, an international team of experts discuss their latest ideas, concepts, methods, and interpretations with supporting examples. This volume is intended for advanced students and specialists in psychobiology, neuroscience, neuroendocrinology, and psychiatry but might also be interest to anyone concerned with understanding the Neuroendocrine correlates of sleep/wakefulness. The contributions are directed more towards providing an integrated view of the field from the perspective of the authors, rather than being a compendium of recent results. The intent is to provide a reference book for recent and future workers in this and related areas of medicine and biology. Each topic in this volume has received the attention of a panel of authors who have responded to our request to review and place into perspective the major issues, which will undoubtedly confront newcomers to the field. The topics dealt with in Neuroendocrine correlates of Sleep/wakefulness are both diverse and complex. The editors hope that this volume will provide an authoritative summary of important issues in the neuroendocrine correlates of sleep/wakefulness. We also hope that it will motivate new researchers to join the quest for solutions to the problems that have been identified by our contributing authors.

The need to continually discover new agents for the control or treatment of invertebrate pests and pathogens is undeniable. Agriculture, both animal and plant, succeeds only to the extent that arthropod and helminth consumers, vectors and pathogens can be kept at bay. Humans and their companion animals are also plagued by invertebrate parasites. The deployment of chemical agents for these purposes inevitably elicits the selection of resistant populations of the targets of control, necessitating a regular introduction of new kinds of molecules. Experience in other areas of chemotherapy has shown that a thorough understanding of the biology of disease is an essential platform upon which to build a discovery program. Unfortunately, investment of research resources into understanding the basic physiology of invertebrates as a strategy to illuminate new molecular targets for pesticide and parasiticide discovery has been scarce, and the pace of introduction of new molecules for these indications has been slowed as a result. An exciting and so far unexploited area to explore in this regard is invertebrate neuropeptide physiology. This book was assembled to focus attention on this promising field by compiling a comprehensive review of recent research on neuropeptides in arthropods and helminths, with contributions from many of the leading laboratories working on these systems.

Novel Approaches into the Origins of Neurodevelopmental Disorders: The Fetal Physiology Foundation Over the past two decades, autism, a neurodevelopmental disorder that is defined by behavior and was once believed to be rare, became recognized in increasing numbers of children and recently received distinction as an "epidemic" [1]. While numbers of affected children have steadily increased, our knowledge is still ins- ficient to explain autism's diverse causes and broad range of presentations. Despite remarkable progress in research, available medical diagnostic testing applies only to a small minority of affected children. Thus, scientifically based explanations with which physicians can diagnose and treat the majority of children with autism and advise their parents are quite limited. Our society and scientific community were unprepared for the rise in autism, which explains our present inability to understand most of its causes. Researchers in neurodevelopmental disorders have long been aware of other disorders that, despite extensive efforts, have not yielded clear genetic or environmental origins, and autism has become symbolic of the need for new approaches to research into these complex conditions. Although autism has captured our attention in recent years, the prevalence of other neurodevelopmental disorders such as attention de- cit hyperactivity disorder (ADHD) and bipolar disorder, among others, also has been increasing [2-4].

The rapidly evolving ?eld of protein science has now come to realize the ubiquity and importance of protein-protein interactions. It had been known for some time that proteins may interact with each other to form functional complexes, but it was thought to be the property of only a handful of key proteins. However, with the advent of hi- throughput proteomics to monitor protein-protein interactions at an organism level, we can now safely state that protein-protein interactions are the norm and not the exception.

Part II of the book addresses specific translational or clinical applications for PNA and related antisense biomolecules. The editors have succeeded in presenting a balanced yet broad view of the methods available for gene targeting and modification.

This volume will explore the most recent findings on cellular mechanisms of inhibitory plasticity and its functional role in shaping neuronal circuits, their rewiring in response to experience, drug addiction and in neuropathology. Inhibitory Synaptic Plasticity will be of particular interest to neuroscientists and neurophysiologists.

This book summarizes 20 years of work on the kinetics of blood-brain transfer and metabolism mechanisms in mammalian brain. The substances affiliated with these mechanisms include glucose, amino acids, monocarboxylic acids, and oxygen. These substances are important to energy metabolism and neurotransmission in the mammalian brain at rest and during activation. To understand the processes addressed by these mechanisms, the book examines the kinetics of compartmentation and compartmental analysis, particularly as they relate to transporter, enzyme, and receptor function. Compartments are subsets of substances separated by transporters and receptors in membranes, and enzymes in cells. This book is divided in six major chapters covering compartmental analysis, kinetic analysis of transport and metabolism, blood-brain transfer and metabolism of glucose, amino acids, and oxygen, and amino acid metabolism and interaction of amino acid metabolites with receptors.

The book "Paradigm Shift for Future Tennis" starts with revelations that make obvious the limitations of today's tennis, which does not use the laws of modern Biomechanics and Neurophysiology. The second part of the book includes a new approach to the quantum mind of a champion. It will reveal the secret weapon of Roger Federer and the blueprint of a future tennis champion. This book will expose the new tennis shot emerging from the field of sports science. It is a real weapon, which can generate a ball-speed similar to that of the first serve: the Power High-Forehand. Its aim is to generate maximal possible racket-head speed while players do not wait for the ball to bounce. This is both a tactical and psychological basis for the future tennis game. This aggressive interceptive psychology will shape the minds of future tennis champions. High racket-head speed can be achieved using the stretch-reflex, without big loops and swings. Weapons of a future tennis game will comprise of whip-like tennis serves and ground strokes, based on the stretch-reflex, and using the whole body in a fluid and integrated manner, thus manifesting a superb combination of speed and strength. Restructure your brain and apply the power of state of the art biomechanical, mathematical, medical, neural, cognitive, and quantum computational intelligence to understand the tennis of today and the future!

Increasing interest in the study of coordinated activity of brain cell ensembles reflects the current conceptualization of brain information processing and cognition. It is thought that cognitive processes involve not only serial stages of sensory signal processing, but also massive parallel information processing circuitries, and therefore it is the coordinated activity of neuronal networks of brains that give rise to cognition and consciousness in general. While the concepts and techniques to measure synchronization are relatively well characterized and developed in the mathematics and physics community, the measurement of coordinated activity derived from brain signals is not a trivial task, and is currently a subject of debate. Coordinated Activity in the Brain: Measurements and Relevance to Brain Function and Behavior addresses conceptual and methodological limitations, as well as advantages, in the assessment of cellular coordinated activity from neurophysiological recordings. The book offers a broad overview of the field for investigators working in a variety of disciplines (neuroscience, biophysics, mathematics, physics, neurology, neurosurgery, psychology, biomedical engineering, computer science/computational biology), and introduces future trends for understanding brain activity and its relation to cognition and pathologies. This work will be valuable to professional investigators and clinicians, graduate and post-graduate students in related fields of neuroscience and biophysics, and to anyone interested in signal analysis techniques for studying brain function.

As the first primer on the effects of exercise on human hypertension, Effects of Exercise on Hypertension: From Cells to Physiological Systems provides the state-of-the-art effects of exercise on the many possible mechanisms underlying essential hypertension in humans. The book contains chapters by distinguished experts on the effects of exercise on physiological systems known to be involved in hypertension development and maintenance as well as less well known aspects of hypertension such as 24-hour ambulatory blood pressure profile and oxidative stress. An emerging area, the effects of resistance exercise training on blood pressure is also covered. A unique aspect of the book is that it covers the effects of exercise mimetics on vascular cell adaptations in order to begin to elucidate some of the cellular mechanisms that may underlie blood pressure reductions with exercise training. Lastly, the book will end with a chapter on the interactive effects of genes and exercise on blood pressure. Chapters are grouped by physiological system or mechanism. The text begins with two overview chapters; one on the general effects of aerobic exercise training and the second on the general effects of resistance exercise training on blood pressure. Each chapter begins with a bulleted list of key points. Effects of Exercise on Hypertension: From Cells to Physiological Systems will be of great value to professional individuals in cardiovascular medicine, the cardiovascular sciences, allied health care professionals, and medical and graduate students in the cardiovascular sciences and medicine.

Protein conversion from a water-soluble native conformation to the insoluble aggregates and fibrils, which can deposit in amyloid plaques, underlies more than 20 human diseases, representing a major public health problem and a scientific challenge. Such a conversion is called protein misfolding. Protein misfolding can also involve errors in the topology of the folded proteins and their assembly in lipid membranes. Lipids are found in nearly all amyloid deposits in vivo, and can critically influence protein misfolding in vitro and in vivo in many different ways. This book focuses on recent advances in our understanding of the role of lipids in modulating the misfolding of various proteins. The main emphasis is on the basic biophysical studies that address molecular basis of protein misfolding and amyloid formation, and the role of lipids in this complex process.

This book puts hydrogen sulfide in context with other gaseous mediators such as nitric oxide and carbon monoxide, reviews the available mechanisms for its biosynthesis and describes its physiological and pathophysiological roles in a wide variety of disease states. Hydrogen sulfide has recently been discovered to be a naturally occurring gaseous mediator in the body. Over a relatively short period of time this evanescent gas has been revealed to play key roles in a range of physiological processes including control of blood vessel caliber and hence blood pressure and in the regulation of nerve function both in the brain and the periphery. Disorders concerning the biosynthesis or activity of hydrogen sulfide may also predispose the body to disease states such as inflammation, cardiovascular and neurological disorders. Interest in this novel gas has been high in recent years and many research groups worldwide have described its individual biological effects. Moreover, medicinal chemists are beginning to synthesize novel organic molecules that release this gas at defined rates with a view to exploiting these new compounds for therapeutic benefit.

The aim of this book is to present current views about physical activity and the benefits of physical activity in preventing and ameliorating various health conditions that are of worldwide concern. This book was developed as a compilation of the accomplishments of the five-year Global COE (Center of Excellence) "Sport Sciences for the Promotion of Active Life" Program at the Faculty of Sport Sciences of Waseda University, Saitama, Japan. The first part establishes the research methodology and discusses the current status of physical activity. Topics covered include the prevalence of physical inactivity and highly sedentary behavior in different populations as well as strategies that can be adopted to promote physical activity. The second part focuses on the physiological effects of physical activity. Topics covered include physiological responses to exercise by the autonomic nervous system, the endocrine system, vascular functioning, postprandial blood glucose control, and inflammatory processes. The relationship between exercise and appetite is discussed, as is the influence of exercise on food intake and weight regulation. Additionally, the influence of exercise on protein regulation and posttranslational modifications is introduced. The final part discusses the role of physical activity in preventing lifestyle-related health issues and improving the quality of life, especially for the elderly. The contents should be of interest to anyone who is concerned with the human physiologic response to exercise and the promotion of healthy lifestyles, including sports and exercise science researchers as well as those involved with medicine, public health, physiology, nutrition, and elder care.

That precursors of adult coronary artery disease, hypertension, and type II diabetes begin in childhood have been clearly established by the Bogalusa Heart Study. This unique research program has been able to follow a biracial (black/white) population over 35 years from childhood through mid-adulthood to provide perspectives on the natural history of adult heart diseases. Not only do these observations describe trajectories of cardio-metabolic risk variables leading to these diseases but provide a rationale for the need to begin prevention beginning in childhood. The trajectories of the burden of cardio-metabolic risk variables in the context of their fetal origin and chromosome telomere dynamics provide some insight into the metabolic imprinting in utero and aging process. The observed racial contrasts on cardio-metabolic risk variables implicate various biologic pathways interacting with environment contributing to the high morbidity and mortality from related diseases in our population. To address the seriousness of the onset of cardiovascular disease in youth, approaches to primordial prevention are described focussing on childhood health education as an important aspect of Preventive Cardiology.
