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.
Since its ?rst description in 1942 in both serum and cerebrospinal ?uid, transthyretin (TTR) has had an eventful history, including changes in name from "prealbumin" to "thyroxine-binding prealbumin" to "transthyretin" as knowledge increased about its functions. TTR is synthesised in a wide range of tissues in humans and other eutherian mammals: the liver, choroid plexus (blood- cerebrospinal ?uid barrier), retinal pigment epithelium of the eye, pancreas, intestine and meninges. However, its sites of synthesis are more restricted in other vertebrates. This implies that the number of tissues synthesising TTR during vertebrate evolution has increased, and raises questions about the selection pressures governing TTR synthesis. TTR is most widely known as a distributor of thyroid hormones. In addition, TTR binds retinol-binding protein, which binds retinol. In this way, TTR is also involved with retinoid distribution. More recently, TTR has been demonstrated to bind a wide variety of endocrine disruptors including drugs, pollutants, industrial compounds, heavy metals, and some naturally occurring plant ?avonoids. These not only interfere with thyroid hormone delivery in the body, but also transport such endocrine disruptors into the brain, where they have the potential to accumulate.
Methods in Bone Biology is unique in being devoted to describing the methodology used by bone researchers.

A qualitative leap in the understanding of cardiovascular and n- ral regulation by the renin-angiotensin system, and of the role of this s- tem in tissue damage, has occurred as a result of the many recent advances in molecular genetic techniques. The cloning of the genes for the components of the renin-angiotensin system, the design of specific angiotensin receptor ligands, and the use of embryonic gene targeting te- niques for the creation of mutant strains have established that the renin- angiotensin system is important in blood pressure regulation, ion and fluid homeostasis, and tissue growth and remodeling Further investigation of the mechanisms by which this system p- ticipates in cardiovascular regulation may shed some light on the pat- genesis of several cardiovascular diseases, e. g. , hypertension, congestive heart failure, and chronic renal failure. Despite the promise of this system as a target for therapeutic interventions for these diseases, there are great challenges in the integration of the attempts to close the gap between the traditional literature of medicine and the explosion of information from the new technologies. This book's title, Angiotensin Protocols, reflects the authors' strong efforts to translate expert knowledge into easy-to-follow practice. The book opens with introductory chapters, and each specialty section provides detailed methods covering a wide variety of techniques, ranging from genetic manipulation of targeted genes to functional studies of the renin- angiotensin system.
This award-winning thesis investigates the mechanisms underlying cardiac arrhythmia development and termination from an entirely new perspective. By viewing the heart as a complex system, the author uses theoretical tools from nonlinear dynamics combined with numerical simulations and experiments to achieve insights into the relationship between its structure and dynamics, thereby paving the way towards innovative low-energy defibrillation strategies. The work tackles, among other things: the effect of substrate heterogeneity on the spatial-temporal dynamics of cardiac arrhythmias and ways in which weak pulsed electric fields can be used to control these dynamics in heterogeneous cardiac tissue. The long-term vision of this research is to replace the current strategy of applying painful and sometimes tissue damaging electric shock - currently the only reliable way to terminate life-threatening fibrillation - by a more subtle but equally effective intervention. The book maps out a number of promising research directions for biophysicists and medical researchers working on the origins and treatment of cardiac arrhythmias.
As the current millennium steams towards a close, one cannot help but look with amazement at the incredible amount of progress that has been achieved in medicine in just the last few decades. A key contributing factor to this success has been the importation and blending of ideas and techniques from disciplines outside the traditional borders of medical science. In recent years, the most well-known example is the cross-pollination between molecular biology and medicine. Advances driven by this potent combination have spawned the vision of a future where cures based on gene therapy become commonplace. Yet, as we continue our search for "magic bullets" in the quest to eradicate disease, it important to recognize the value of other less-heralded interdisciplinary efforts that have laid a large part of the foundation of present-day medicine. In pulmonary medicine, the contribution from the bioengineers (a diverse collection of individuals cross-bred to various degrees in mathematical modeling and experimental physiology) has been larger and more sustained than in many other medical specialties. It is easy to point to the vast array of ventilators, blood-gas analyzers, oximeters, pulmonary function devices, and respiration monitors that are present in any modern clinical setting as solid evidence of the successful synergy between engineering science and pulmonary medicine. However, one must not forget the less tangible, but perhaps more important, contributions that have been derived from mathematical modeling and computer simulation, without which many of these modern instruments would not have come into existence.

The number of mouse models that are available for the study of human genetic neurological disorders is large and growing rapidly. Therefore, it was difficult to select the models that were reviewed in this volume. Clearly, there are important models that are not discussed, and perhaps a volume twice this size would have been more appropriate. Moreover, the pace at which new models are being developed and analyzed is rapid. As this volume goes to press, I am sure that additional mouse genes responsible for naturally occurring neurological disorders are being discovered and that many new transgenic and mutant mouse strains are being developed. Therefore, this volume should not be viewed as a comprehensive compendium, but rather as an update of work in progress. It is exhilarating to witness the fast pace at which these models are being established as important tools in the study of basic neuroscience and neurological disorders. It will be even more exciting to see their utilization in the development and testing of therapeutic interventions for these diseases. I would like to thank each of the authors who have contributed to this volume for their time and their expertise. I would also like to thank Drs. Timothy Coetzee and Joshua Corbin for their advice in the selection of the topics covered. I am deeply indebted to Dr. Kunihiko Suzuki, who first approached me with the idea for this volume, for his guidance throughout its preparation.

The multiple actions of estrogens on different cell types have not only intrigued endocrinology researchers but also inspired the development of selective estrogen receptor modulators, or SERMs, that modulate estrogen signaling in a cell type-specific manner. Current molecular understanding of estrogen action has greatly profited from advances in molecular cell biology to dissect the mechanisms of estrogen-regulated gene expression in target cells, from in vivo analyses using genetic models deficient in estrogen signaling and from synthetic estrogen receptor ligands with isoform- or pathway-selective activity. These advances, and their implications for clinical use, were discussed by leading researchers from industry and academia during an international symposium held in Berlin, 1-3 March 2006.

Lipobiology is an interdisciplinary field which incorporates critical aspects of lipid and lipoprotein chemistry into the disciplines of cell biology and physiology. During the last decade, advances in our understanding of the structure and function of lipids, biological membranes and lipid-derived second messengers have underscored the importance of lipids in the regulation of cellular function. This series focuses on salient aspects of the role of lipids in metabolic regulation and cellular activation, with emphasis on emerging concepts and technologies. One goal of this series is to formulate cohesive criteria upon which a foundation for the evaluation of recent work can be based and future directions of research identified.

Awarded with the 2018 Prose Award in Clinical Medicine, the third edition of Principles of Gender-Specific Medicine explored and described exciting new areas in biomedicine that integrated technology into the treatment of disease and the augmentation of human function. Novel topics such as the sex-specific aspects of space medicine, the development and the use of genderized robots and a discussion of cyborgs were included in the third edition, providing a preview of the expanding world of sex-specific physiology and therapeutics. This Fourth Edition is a continuation of the mission to trace the relevance of biological sex to normal function and to the experience of disease in humans. We are now twenty years into the postgenomic era. The investigation of how the genome produces the phenome has led to fascinating insights as well as yet unanswered questions. Principles of Gender-Specific Medicine, Fourth Edition, has a central theme: discuss advances in understanding the role of epigenetics in regulating gene expression in a dynamic, sex-specific way during human life. It explores the protean role of epigenetics in human physiology, the relevance of environmental experience to human function, the therapeutic promise of cutting-edge methodologies like gene manipulation, the preparation of humans for space travel, the use of artificial intelligence in detection and therapeutic decisions concerning disease states, the possibilities for technological support of not only compromised individuals but of the augmentation of human function, and an analysis of the benefits, limitations and issues that surround our current expectations of personalized medicine.

How is the heartbeat generated? What controls the strength of contraction of heart muscle? What are the links between cardiac structure and function? How does our understanding of skeletal and smooth muscle and non-muscle cells influence our thinking about force development in the heart? Are there important species differences in how contraction is regulated in the heart? How do the new molecular data fit together in understanding the heart beat? What goes wrong in ischemia, hypertrophy, and heart failure? This book paints a modern portrait' of how the heart works and in this picture the author shows a close-up of the structural, biochemical, and physiological links between excitation and contraction. The author takes the reader through a series of important, interrelated topics with great clarity and continuity and also includes many useful illustrations and tables. The book starts by considering the cellular structures involved in excitation-contraction coupling and then described the characteristics of the myofilaments as the end effector of excitation-contraction coupling. A general scheme of calcium regulation is described and the possible sources and sinks of calcium are discussed in simple, but quantitative terms. The cardiac action potential and its many underlying currents are reviewed. Then the characteristics of some key calcium transport systems (calcium channels, sodium/calcium exchange and SR calcium uptake and release) are discussed in detail. This is then built into a more integrated picture of calcium regulation in succeeding chapters by detailed discussions of excitation-calcium coupling mechanisms (in skeletal, cardiac, and smooth muscle), the interplay betweencalcium regulatory processes, and finally mechanisms of cardiac inotropy, calcium overload, and dysfunction (e.g., ischemia, hypertrophy, and heart failure). Excitation-Contraction Coupling and Cardiac Contractile Force &endash; Second Edition is an invaluable source of information for anyone who is interested in how the heart beat is controlled and especially suited for students of the cardiovascular system at all levels from medical/graduate students through senior investigators in related fields.
Our purpose in writing this book was to produce a clinically-oriented, non-multi-au- thored textbook ofcardiac electrophysiology that would be useful to practicing electro- physiologists, cardiologists, fellows in training as well as associated electrophysiology professionals, including nurses and technologists. While all clinical textbooks risk be- coming outdated even before they're published, and few textbooks ofa manageable size can claim to be completely comprehensive, our goal was to produce a book that system- atically presents a thorough discussion ofthe fundamental principles and concepts im- portant to the practice of clinical electrophysiology. We do not discuss basic cellular electrophysiology for its sake alone, but instead include basic science material only when itis helpful in explaining the overlying clinical principles. Cardiac electrophysiology, as with any subspecialty, behaves as a living organism with continuous evolution of its standards and practices. However, even though the details and tools of management (catheters, drugs, devices, etc. ) may change with dazzling speed, the fundamental princi- ples ofdiagnosis and management generally change very little and they remain the criti- cal underpinning ofthe day-to-day management ofpatients with cardiac arrhythmias. In the first third ofthe book we present the principles ofclinical cardiac electrophysiolo- gy as it is currently practiced.
This book is the compilation of papers presented at the International Symposium on In Vivo Body Composition Studies, held in Houston, Texas, November 10-12, 1992. The purpose of this conference was to report on the state-of-the-art techniques for in vivo body composition measurements and to present the most recent human data on normal body composition and changes during disease. This conference was the third in a series of meetings on body composition studies held in North America, and follows the successful meetings at Brookhaven National Laboratory in 1986, and the one in Toronto in 1989. A large number of excellent research papers were offered for consideration at this Conference which demonstrates the rapid growth of the field in the last three years. However, we had to limit the presentations to approximately 90 papers which provided a broad spectrum of the applications and recent interest in the subject. The proceedings of the Brookhaven meeting "In Vivo Body Composition Studies," is published by The Institute of Physical Sciences in Medicine, London. The proceedings of the Toronto meeting "In Vivo Body Composition Studies" was published by Plenum Press in its basic life science series. Both these meetings placed more emphasis on technical aspects while the current Houston meeting tried to emphasize more the emerging clinical applications of these techniques. The general sessions used at the Conference for presentations forms the basis of the order of appearance of the papers in this book.
The International Society on Oxygen Transport to Tissue (ISOTT, www. isott. info) is an interdisciplinary society comprising about 250 members worldwide. Its purpose is to further the understanding of all aspects of the processes involved in the transport of oxygen from the air to its ultimate consumption in the cells of the various organs of the body. The annual meeting brings together scientists, engineers, clinicians and mathematicians in a unique int- national forum for the exchange of information and knowledge, the updating of participants on latest developments and techniques, and the discussion of controversial issues within the field of oxygen transport to tissue. Founded in 1973, the society has been the leading platform for the presentation of many of the technological and conceptual developments within the field both at the meetings themselves and in the proceedings of the society. These have been published first by Plenum Publishing (1973), then by Kluwer Academic/Plenum Publishers and presently by Springer Publishing, all in the Advances In Expe- mental Medicine and Biology Series. The 36th Annual ISOTT conference was held in Sapporo, Japan during August 3-7, 2008. It was the second occasion that the ISOTT meeting was held in Japan; the first one was held in the same place in 1987 organized by Professor Masaji Mochizuki.
Evolving technologies starting with tracer studies, and more recently with genomics and proteomics, have provided novel information about the molecular properties of cerebral endothelium and astrocytes; however, further studies must be done in animal models of neurological diseases and in humans to get a clearer understanding of the pathogenesis of blood-brain barrier (BBB) breakdown in nervous system diseases. In The Blood-Brain and Other Neural Barriers: Reviews and Protocols, experts in the field present a series of cutting-edge protocols which can be used to study the barriers. Opening with detailed information on components of the neurovascular unit as well as the blood-cerebrospinal, blood-retinal, and blood-nerve barriers, the book continues with meticulous techniques to image the barriers in humans and experimental animals, followed by cutting-edge molecular techniques to study the BBB and novel models to study the barriers, and it concludes with techniques for the delivery of therapeutic agents across the BBB. Written in the highly successful Methods in Molecular Biology(TM) series format, protocol chapters include introductions to their respective topics, lists of the necessary materials, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and up-to-date, The Blood-Brain and Other Neural Barriers: Reviews and Protocols will aid the research efforts of not only graduate students but also more experienced investigators and support future studies of these vital systems.
Interest in the ability of myocardium to adapt to ischaemic stress has continued to grow since the discovery of ischaemic preconditioning in 1986. In 1993, two reports heralded the recognition of a delayed preconditioning response in the heart, now commonly known as the second window' of protection. Since then, a number of studies have described the ability of delayed preconditioning and related adaptive phenomena to protect against a variety of pathologies in the ischaemic and reperfused myocardium. Our understanding of the cellular mechanisms of sub-acute adaptive cardioprotection has advanced considerably during this period. This compilation of state-of-the-art reviews by those who have made significant contributions to this field provides detailed and critical analysis of this research, from molecular basis to potential clinical relevance. The book aims to provide an authoritative, comprehensive and thoroughly up-to-date overview for scientists and clinicians engaged in, or observing, this rapidly-developing area of heart research. It will also be of interest to those engaged in research on other tissues where ischaemia-reperfusion pathology is of major concern.
The biophysics of excitable membranes and extracellular potential fields emerged at the end of the 18th century, together with electrophysiology, and has been used ever since as a basis for the development of electrophysiological investigations. This holds true even for the contemporary stage of initial discoveries concerning the molecular mechanisms of membrane excitability. The biophysics of ionic channels has gradually revealed the genesis of the ionic currents and of the biopotentials in different excitable structures. On the basis of electrodynamics, the extracellular potential fields in the living body, considered as a volume conductor, have been studied intensively. The knowledge accumulated constitutes the theoretical basis for interpretation of the electrophysiological data. Over a period of more than 15 years a group of Bulgarian investigators led by A. Gydikov has systematically studied the dependence between the intra- and extracellular potentials of the skeletal muscles. The present book summarizes these investigations. Using a great amount of factual material from experiments and model investigations on the skeletal muscle potentials, the author considers: (a) the extracellular potential field of single skeletal muscle fibres and their dependence of the parameters of intracellular action potentials, the geometric parameters of the fibres and of the volume conductor; (b) the potentials of single motor units; (c) the compound and reflex muscle potentials, and (d) the interference electromyogram. The comprehensive consideration of the biophysics of skeletal muscle potentials is of interest to a broad circle of specialists. The book summarizes contemporary knowledge in thisfield and presents a consistent theoretical basis of electromyography which is of great importance not only for the neurological clinic, but also for different fields of applied physiology. |
