The volume Appetite Control provides a comprehensive description of the mechanisms controlling food intake, and thereby energy balance, in the mammalian organism. During the last decade, research in this area has produced a remarkable wealth of information and has characterized the function of numerous peptides, transmitters, and receptors in appetite control. Dysfunction of these circuits leads to obesity, a growing health concern. However, the plethora of mechanistic information is in marked contrasts to an almost complete lack of anti-obesity drugs that meet the safety standards required for the chronic therapy of morbid obesity. Consequently, ongoing research aims to identify additional targets and agents for a pharmacological intervention. Thus, the mechanisms of appetite control as well as all agents interfering with its control are of considerable practical interest. The authors of the volume are distinguished scientists who are leading experts in the field, and who have contributed important, original data to our understanding of the mechanisms of appetite control. They have quite different scientific backgrounds and, together, they represent all relevant disciplines. Thereby, the topics are presented from different points of view, not exclusively from that of pharmacology and neuroendocrinology. Thus, the volume addresses all scientists who are interested in the field of obesity research and the pathophysiology of appetite control."

Science and technology has been used more and more in the last few decades to gain advantage over competitors. Quite often, however, the actual science involved is not published because a suitable journal cannot be found. The Engineering of Sport brings together work from a very diverse range of subjects including Engineering, Physics, Materials and Biomechanics. The Engineering of Sport represent work which was represented at the 1st International Conference on the Engineering of Sport held in Sheffield, UK in July 1996. Many sports were represented and the material covered split into nine topics covering aerodynamics, biomechanics, design, dynamics, instrumentation, materials, mechanics, modelling, motion analysis, and vibrations. It should be of interest to specialists in all areas of sports research.

The volume is thematically arranged, with papers covering different aspects of ergonomics and design. The volume will be of use to researchers, practitioners and students working in different fields of ergonomics.
Quantitative ultrasound (QUS) of bone is a relatively recent research field. The research community is steadily growing, with interdisciplinary branches in acoustics, medical imaging, biomechanics, biomedical engineering, applied mathematics, bone biology and clinical sciences, resulting in significant achievements in new ultrasound technologies to measure bone, as well as models to elucidate the interaction and the propagation of ultrasonic wave in complex bone structures. Hundreds of articles published in specialists journals are accessible from the Web and from electronic libraries. However, no compilation and synthesis of the most recent and significant research exist. The only book on QUS of bone has been published in 1999 at a time when the propagation mechanisms of ultrasound in bone were still largely unknown and the technology was immature. The research community has now reached a critical size, special sessions are organized in major international meetings (e.g., at the World Congress of Biomechanics, the annual meetings of the Acoustical Society of America, International Bone Densitometry Workshop, etc...). Consequently, the time has come for a completely up to date, comprehensive review of the topic. The book will offer the most recent experimental results and theoretical concepts developed so far and is intended for researchers, graduate or undergraduate students, engineers, and clinicians who are involved in the field. The central part of the book covers the physics of ultrasound propagation in bone. Our goal is to give the reader an extensive view of the mathematical and numerical models as an aid to understand the QUS potential and the types of variables that can be determined by QUS in order to characterize bone strength. The propagation of sound in bone is still subject of intensive research. Different models have been proposed (for example, the Biot theory of poroealasticity and the theory of scattering have been used to describe wave propagation in cancellous bone, whereas propagation in cortical bone falls in the scope of guided waves theories). An extensive review of the models has not been published so far. We intend in this book to present in details the models that are used to solve the direct problem and strategies that are currently developed to address the inverse problem. This will include analytical theories and numerical approaches that have grown exponentially in recent years. Most recent experimental findings and technological developments will also be comprehensively reviewed.
This volume, based on the International Congress Creatine: From Basic Science to Clinical Application, held in Milan on June 4, 1999, outlines the physiological role of creatine in the human body as well as its possible role in different pathological conditions. Creatine is already used as a dietary supplement to augment muscle performance in healthy individuals and inpatients with immobilizing diseases, such as complex fractures. There is also an increasing interest in its administration in a growing number of clinical conditions. A specific deficit of endogenous synthesis of creatine which responds to high dosage exogenous supplementation has been described. In cardiac failure and in chronic obstructive pulmonary disease, creatine improves the contractility of the muscular system. Promising effects of this substance have also been described in animal models of neurodegenerative disorders, such as amyotrophic lateral sclerosis, and in some mitochondrial cytopathies. This volume is of obvious interest to basic scientists working on the physiology of creatine and to clinicians interested in its medical indications.
The maintenance of arterial blood pressure and the distribution of blood flow to the various organs of the body depends on the control of the pumping action of the heart and of the resistance of the vascular beds in the individual organs in accordance with their metabolic needs. These controls are achieved through the integrated actions of circulat ing hormones, humoral factors that are synthesized and released in the heart and blood vessels, and the autonomic nervous system. The heart, however, is not only the target for the direct and indirect actions of a number of hormones and humoral factors, it is also an endocrine organ in the traditional sense, synthesizing and secreting into the circulation chemical factors that act at distant sites. In this treatise, Hormones and the Heart in Health and Disease, we interpret "endocrinology" broadly and consider traditional hormones as well as autocoids that are secreted by the heart or that act on it. In this overview, the relevant chapters are indicated in parentheses. The discovery of atrial natriuretic peptide (ANP; atrial natriuretic factor, ANF) in the 1980s indicated that the heart does indeed function as an endocrine organ in the classic sense. ANP (Chapter I) is synthesized in the heart and secreted into the circulation for actions on the kidney, where it is a potent natriuretic agent, and on the vasculature, where it causes vasodilation. ANP can also affect myocardial contractility."
This book provides a state-of-the-art update, as well as perspectives on future directions of research and clinical applications in the implementation of biomechanical and biophysical experimental, theoretical and computational models which are relevant to military medicine. Such experimental and modeling efforts are helpful, on the one hand, in understanding the aetiology, pathophysiology and dynamics of injury development and on the other hand in guiding the development of better equipment and protective gear or devices that should ultimately reduce the prevalence and incidence of injuries or lessen their hazardous effects. The book is useful for military-oriented biomedical engineers and medical physicists, as well as for military physiologists and other medical specialists who are interested in the science and technology implemented in modern investigations of military related injuries.
This book addresses the application of infrared thermography in sports, examining the main benefits of this non-invasive, non-radiating and low-cost technique. Aspects covered include the detection of injuries in sports medicine, the assessment of sports performance due to the existing link between physical fitness and thermoregulation and the analysis of heat transfer for sports garments and sports equipment. Although infrared thermography is broadly considered to be a fast and easy-to-use tool, the ability to deliver accurate and repeatable measurements is an important consideration. Furthermore, it is important to be familiar with the latest sports studies published on this technique to understand its potential and limitations. Accordingly, this book establishes a vital link between laboratory tests and the sports field.
This book describes the recent advancement of basic research on the biology of aging and longevity studies in various organisms, as well as the neurobiology of aging and neurodegeneration mechanisms. Chapters present new findings and conceptual developments concerning the basic mechanisms of aging and longevity determination. As a follow-up volume to the previous book Aging Mechanisms (2015), it overviews the rapid progress of aging research introducing new topics from leading laboratories in Japan. Chapter contributors are selected based on recent scientific achievements on the mechanisms of aging in various model organisms, including yeast, worm (C. elegans), fly (Drosophila), mice, and rats. Chapters are ordered from the discussion on molecular and cellular levels to physiological and systemic levels. The book also provides an overview of aging science in the region and helps readers quickly grasp who is doing what in this research area. As the aging of population becomes an ever more pressing issue in Asia, advancing the understanding of basic mechanisms of organism aging and longevity determination will be crucial to developing more effective therapies and protective strategies. Researchers and graduate students in biomedical aging research will find this as a rich source of information and a stimulus to novel research directions.
Like many of us, journalist David K. Randall never gave sleep much thought. That is, until he began sleepwalking. One midnight crash into a hallway wall sent him on an investigation into the strange science of sleep. In Dreamland, Randall explores the research that is investigating those dark hours that make up nearly a third of our lives. Taking readers from military battlefields to children s bedrooms, Dreamland shows that sleep isn't as simple as it seems. Why did the results of one sleep study change the bookmakers odds for certain Monday Night Football games? Do women sleep differently than men? And if you happen to kill someone while you are sleepwalking, does that count as murder? This book is a tour of the often odd, sometimes disturbing, and always fascinating things that go on in the peculiar world of sleep. You ll never look at your pillow the same way again."
Studies over the past decade have continued to bring tremendous advances to our understanding of bone biology. New pathways have been discovered and expanded our knowledge of the ways in which genes and gene products affect bone cells and thereby bone mass and bone strength. In Bone Research Protocols, Second Edition, expert researchers in the field detail many methods commonly used to study bone biology. Focusing mainly on in vitro methods, this volume gives techniques for isolation, culture and functional analysis of all bone cell types and details a range of imaging methods, including light and ultrastructural microscopy and live cell imaging. Some important in vivo techniques are included, such as analysis of bone resorption and imaging using X rays, fluorescent or luminescent techniques. Methods for study of proteins and nucleic acid are included and methods for analysis of bone composition, measurement of bone strength, and response to mechanical stimulation are described. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls.

This volume is a record of the proceedings of a festspiel held to
honor Jozef F. Zwislocki for his outstanding contributions to
science and to Syracuse University. His contributions to the
knowledge of the hydromechanical, neurophysiological, and
perceptual mechanisms of the auditory system are truly monumental.
In addition, his contributions to the comprehension of the
mammalian auditory system include not only landmark ideas, but also
many of the experimental findings in psychoacoustics and peripheral
auditory physiology that constitute the database which has provided
a springboard for research in laboratories throughout the world.
His efforts to link physics, biology, and psychophysics to create a
basis for our understanding of the nervous system have had an
influence that extends far beyond the science of acoustics.
This book covers key topics in polyamine research from a range of organisms, including plants, mammals, and prokaryotes such as bacteria and archaea. The book provides an introduction to general concepts in the field of polyamine research, as well as more detailed information. With the availability of genome sequence data from a broad range of organisms, the evolution of the genes involved in polyamine metabolism is discussed. The mode of action of polyamines has been shown to be dependent on cation channels, and this mechanism is described in the book. The origin of polyamine transporters (from bacteria, yeasts, and plants) is described. The various effects of polyamines on growth and survival are also documented. The book details the mechanisms of polyamine homeostasis and the role of polyamine molecules as precursors of secondary metabolites such as plant alkaloids and toxins derived from spiders and wasps. The role of polyamines in longevity and disease is discussed. A link between polyamine contents and cancer progression is reported, as is the use of polyamine metabolites as diagnostic markers in the initial stages of cancer. Moreover, a novel approach that utilizes the polyamine pathway of a parasite as a drug target in African sleeping sickness is described. Therefore, this book is a valuable resource, both as a textbook for undergraduate and graduate students and also as a reference book for front-line polyamine researchers.

The result of the first Appalachian Conference on neurodynamics,
this volume focuses on processing in biological neural networks.
How do brain processes become organized during decision making?
That is, what are the neural antecedents that determine which
course of action is to be pursued? Half of the contributions deal
with modelling synapto-dendritic and neural ultrastructural
processes; the remainder, with laboratory research findings, often
cast in terms of the models. The interchanges at the conference and
the ensuing publication also provide a foundation for further
meetings. These will address how processes in different brain
systems, coactive with the neural residues of experience and with
sensory input, determine decisions.
