This book is concernced with the process of cell death in human cells by programmed cell death or apoptosis, and the modulation of this process by drugs. This is a new field of study and this volume represents the first comprehensive treatment of this subject matter. Its focus is on human biology and medicine. Apoptosis is a very prevalent type of cell death with importance in human diseases such as cancer, Alzheimer's disease and autoimmune disorders. The book combines the expertise of leading scientists and writers from fields as diverse as neurosciences, immunology, pathology and cancer research. There is detailed analysis of the molecular and cellular aspects of apoptosis including the specific genes and molecules involved in the regulation of this special form of programmed cell death. Scientists, clinicians and researchers involved in studies of human biology and medicine will find this book an excellent resource.
Venous Ulcers, Second Edition, provides a comprehensive synthesis of evidence-based recommendations and the highest level of expertise from a leading group of doctors, which is a fundamental constituent for the appropriate management of nonhealing venous wounds in everyday practice. This book offers a fertile environment for a complete understanding of genetics and molecular and biochemical mechanisms that lead to the development and progression of venous ulcers, which is essential for elucidating the underlying pathophysiology and can be utilized for developing novel therapies and accessing previously inaccessible areas of research. Socioeconomic impact, impact on health-related quality of life, the clinical course of the disease, and diagnostic algorithms are elaborated in detail. All currently available treatment modalities are explained in a clinically applicable approach with particular emphasis on operative technique, technical feasibility, success rates (both clinical and technical), and side effects. Lastly, this book elaborates on special diagnostic considerations and management of the most complex patients, often requiring the highest level of expertise for successful treatment.
The 14th volume in the series will focus on cutting edge research at the interface of hypoxia and exercise. The work will cover the range from molecular mechanisms of muscle fatigue and muscle wasting to whole body exercise on the world 's highest mountains. State of the art papers on training at high altitude for low altitude athletic performance will also be featured.
Nearly everything making up what we call the "environment" of a plant has an infuence on the way it grows. Sunlight, te- perature, moisture contents of soil and atmosphere and vib- tions are all obvious examples of environmental components, and transient variations in their amount or intensity lead the plant to manifest more or less immediate responses. Small changes in carbon dioxide level in the atmosphere can even have effects, but these take a longer time to be registered - at least those that are visible, albeit at the microscopic level. Plants meet the challenges of the environment by means of acclimation. In this respect, plants are notable for the pl- ticity of their development. However, where morphological or physiological plasticity is no longer an option, the responses would be by means of adaptations as a result of genetic - lection or genetic "assimilation" (Waddington 1957). Thus, a feature that was once a facultative transient response to an environmental perturbation becomes a constitutive charac- ristic of plant structure or function. It is in this way that the environment continually molds the way in which plants de- lop, and also defnes the areas upon planet Earth where they will thrive.

This contributed volume presents the current state of research on regenerative rehabilitation across a broad range of neuro- and musculoskeletal tissues. At its core, the primary goal of regenerative rehabilitation is to restore function after damage to bones, skeletal muscles, cartilage, ligaments/tendons, or tissues of the central and peripheral nervous systems. The authors describe the physiology of these neuro- and musculoskeletal tissue types and their inherent plasticity. The latter quality is what enables these tissues to adapt to mechanical and/or chemical cues to improve functional capacity. As a result, readers will learn how regenerative rehabilitation exploits that quality, to trigger positive changes in tissue function. Combining basic, translational, and clinical aspects of the topic, the book offers a valuable resource for both scientists and clinicians in the regenerative rehabilitation field.
The prefrontal cortex is known to play important roles for performing a variety of higher cognitive functions. Among regions of the prefrontal cortex, the dorsolateral prefrontal cortex plays the most important roles for these functions. This book focuses on functions of the dorsolateral prefrontal cortex, summarizes research results obtained mainly by non-human primate studies, and describes neural mechanisms of executive functions that the dorsolateral prefrontal cortex participates. First, to understand the feature of the dorsolateral prefrontal cortex and how its function has been understood, anatomical and functional features of the dorsolateral prefrontal cortex and historical overview of prefrontal functions are described. To understand functions of the prefrontal cortex and neural mechanisms of executive functions, working memory is an important concept and sustained activation during the memory period of working memory tasks is known as a neural mechanism of working memory. Therefore, this book describes features of sustained memory-related activity based on neurophysiological results obtained in the prefrontal cortex and how memory-related activity contributes to executive functions including control of attention, inhibitory control, task management, and planning. And further, this book describes how the dorsolateral prefrontal cortex contributes to neural mechanisms for sensory and motor processing, memory control in multi-task performance, decision-making, metacognition, and top-down control. Thus, this book provides important information regarding neural mechanisms of dorsolateral prefrontal functions to neuroscientists and helps to plan further investigation to understand prefrontal functions in primates and human subjects.

This book is an edited collection of the literature on leptin beginning with the discovery of leptin and a study of its affect on animals and in humans. Chapters will focus on the discovery, history, roles and regulation of leptin in all the major areas of physiology, as well as on assay methods, phylogeny and genetics. The timing of this volume is long overdue and is the first comprehensive coverage of leptin physiology in the field.
The importance of polyamines for all living cells has been recognized since spermine was discovered in human semen more than 300 years ago. Polyamine research intensified when analytical methods were developed for their determination, particularly in tissues and biological fluids. Discovering their close correlation with cancer, and that polyamine concentrations change during the cell cycle, gave reason for further research in this topic. Polyamines in Health and Nutrition concentrates on the direction of polyamine research which has the capacity to influence and benefit our health and which can explain some of the discrepancies and failures of earlier research. It is important to recognize the dietary contribution to the polyamine body pool and to investigate how the polyamine content of the diet can be changed, with the ultimate aim of using this information to improve our health.
The overall scope of this new series will be to evolve an understanding of the genetic basis of (1) how early mesoderm commits to cells of a heart lineage that progressively and irreversibly assemble into a segmented, primary heart tube that can be remodeled into a four-chambered organ, and (2) how blood vessels are derived and assembled both in the heart and in the body. Our central aim is to establish a four-dimensional, spatiotemporal foundation for the heart and blood vessels that can be genetically dissected for function and mechanism. Since Robert DeHaan's seminal chapter "Morphogenesis of the Vertebrate Heart" pub lished in Organogenesis (Holt Reinhart & Winston, NY) in 1965, there have been surprisingly few books devoted to the subject of cardiovascular morphogenesis, despite the enormous growth of interest that occurred nationally and internationally. Most writings on the subject have been schol arly compilations of the proceedings of major national or international symposia or multiauthored volumes, often without a specific theme. What is missing are the unifying concepts that can make sense out of a burgeoning database of facts. The Editorial Board of this new series believes the time has come for a book series dedicated to cardiovascular morphogenesis that will serve not only as an important archival and didactic reference source for those who have recently come into the field but also as a guide to the evolution of a field that is clearly coming of age."

The Copenhagen Muscle Research Centre was founded in 1994 with the support of a grant from the Danish National Research Foundation. Among the goals for the Centre is the organization of research symposia, with the aim of bringing a limited number ofintemation ally renowned scientists together to discuss the latest developments and perspectives in their field. The first Copenhagen Muscle Research Centre Conference was held in 1995 and dealt with cardiovascular regulation. The Second Copenhagen Muscle Research Centre Confer ence was held from October 23-26, 1997. The topic of the Symposium was Muscle Metabo lism: Regulation, Exercise, and Diabetes. Seventy invited scientists from all over the world discussed their latest research related to skeletal muscle metabolism. The speakers were asked to expand on their presentations and to write short, but comprehensive, chapters about their given topics. The result is 28 peer-reviewed and edited chapters covering many if not all aspects of muscle energy metabolism related to exercise and diabetes. Emphasis is on regulation of glucose and fatty acid metabolism and the mechanisms regulating their use as fuels for the muscle during exercise. In addition, abnormalities in the regulation of glucose metabolism in the diabetic state are described. However, amino acid and protein metabolism are also thoroughly discussed. We believe that this volume brings an unparralleled, up to date, and comprehensive review of the frontiers in muscle metabolism. Erik A."
Nutrients have been recognized as essential for maximum growth, successful reproduction, and infection prevention since the 1940s; since that time, the lion's share of nutrient research has focused on defining their role in these processes. Around 1990, however, a major shift began in the way that researchers viewed some nutrients particularly the vitamins. This shift was motivated by the discovery that modest declines in vitamin nutritional status are associated with an increased risk of ill-health and disease (such as neural tube defects, heart disease, and cancer), especially in those populations or individuals who are genetically predisposed. In an effort to expand upon this new understanding of nutrient action, nutritionists are increasingly turning their focus to the mathematical modeling of nutrient kinetic data. The availability of suitably-tagged (isotope) nutrients (such as B-carotene, vitamin A, folate, among others), sensitive analytical methods to trace them in humans (mass spectrometry and accelerator mass spectrometry), and powerful software (capable of solving and manipulating differential equations efficiently and accurately), has allowed researchers to construct mathematical models aimed at characterizing the dynamic and kinetic behavior of key nutrients in vivo in humans at an unparalleled level of detail."
Upon completion of the human genome project over 800 G protein-coupled receptor 1 (GPCR) genes, subdivided into five categories, were identified. These receptors sense a diverse array of stimuli, including peptides, ions, lipid analogues, light and odour, in a discriminating fashion. Subsequently, they transduce a signal from the ligand-receptor complex into numerous cellular responses. The importance of GPCRs is further reflected in the fact that they constitute the most common target for therapeutic drugs across a 2 wide range of human disorders. Phylogenetic analysis of GPCRs produced the GRAFS classification system, which subdivides GPCRs into five discrete families: glutamate, rhodopsin, adhesion, frizzled/taste2 and secretin receptors. The adhesion-GPCR family 2 can be further subdivided into eight groups. The field of adhesion-GPCR biology has indeed become large enough to require a volume dedicated solely to this field. The contributors to this book have made a courageous effort to address the key concepts of adhesion-GPCR biology, including the evolution and biochemistry of adhesion-GPCRs; there are extensive discussions on the functional nature of these receptors during development, the immune response and tumourgenesis. Finally, there are chapters dedicated to adhesion-GPCR signalling, an area of intense investigation.
Excess of homocysteine, a product of the metabolism of the essential amino acid methionine, is associated with poor health, is linked to heart and brain diseases in general human populations, and accelerates mortality in heart disease patients. Neurological and cardiovascular abnormalities occur in patients with severe genetic hyperhomocysteinemia and lead to premature death due to vascular complications. Although it is considered a non-protein amino acid, studies over the past dozen years have discovered mechanisms by which homocysteine becomes a component of proteins. Homocysteine-containing proteins lose their normal biological function and become auto-immunogenic and pro-thrombotic. In this book, the author, a pioneer and a leading contributor to the field, describes up-to date studies of the biological chemistry of homocysteine-containing proteins, as well as pathological consequences and clinical implications of their formation. This is a comprehensive account of the broad range of basic science and medical implications of homocysteine-containing proteins for health and disease.
Introduction to Pathophysiology for Nurses and Healthcare Professionals is the most comprehensive visual survey of pathophysiology affecting each body system. Using full colour illustrations, photographs and learning features, this book makes the potentially complex subject of pathophysiology interesting and accessible. Each chapter discusses the common pathologies for each body system, along with the prevalence of the disease in the UK. The text is aimed at students and healthcare professionals who are learning about applied pathophysiology and related pharmacology and is an ideal introduction to the subject, enabling care to be based on a sound foundation of what is going on in the body.
Many complex molecular interactions are involved in the development of the mammalian brain. Molecules serving as guidance cues for migratory cells, growing axons and for recognition of postsynaptic targets are a major topic for research because they are directly involved in the formation of neuronal circuits, thus creating the foundation for subsequent functional refinement through interactions with the environment. In addition, most guidance cue molecules are also involved in plasticity, damage repair and regeneration in the adult brain. This volume reviews current knowledge on major classes of molecules involved in: guidance of growing axons; tau proteins involved in the establishment of axonal polarity, outgrowth and contact recognition; gangliosides and lectins involved in neuronal migration, neurite outgrowth and contact recognition; and myelin molecules that inhibit nerve regeneration.
Almost all bodily functions are dependent on activity of the autonomic nervous system - from the cardiovascular system, the gastrointestinal tract, the evacuative and sexual organs, to the regulation of temperature, metabolism and tissue defence. Balanced functioning of each aspect of this system is an important basis of our life and well-being. In this long-awaited second edition, the author, a leading figure in this field, provides an up-to-date and detailed description of the cellular and integrative organization of the autonomic nervous system, covering both peripheral and central aspects. The book exposes modern neurobiological concepts that allow us to understand why this system normally runs so smoothly and why its deterioration has such disastrous consequences. This broad overview will appeal to researchers and advanced undergraduate students of the various biological and medical sciences studying how the autonomic nervous system works and to clinicians and physical therapists whose practice involves systems dependent on autonomic functions.
This book is about the theory of Hot and Cold, a mutual fundamental base of traditional medicines all around the world. The theory describes the dynamic balance state of the body on the axis of hot and cold for each individual and proposes the fact that deviation from this equilibrium is a predisposing factor for diseases. Such an approach helps practitioners to provide treatments tailored to the patient's condition, not the disease. This book, for the first time, has gathered native descriptions of Hot and Cold theory in different traditional medicines, including traditional Chinese medicine, Persian (Humoral, Unani) medicine, Ayurvedic medicine and Latin American and Caribbean medicines. After defining the common ground, contemporary research - in nutrition, pharmacology, physiology and systems biology - has been explored using scientific methodology. This work is the result of an international collaboration of more than 30 scientists and scholars with high reputations in their fields. Hot and Cold theory, as a holistic individualized approach in prevention, diagnosis and treatment, can be merged into the novel fast-paced concepts in systems biology and precision medicine. Through this bridge, the authors propose that the Hot and Cold theory should be revisited more deeply by medical scientists, who are the main audience of this book, to pave the way towards integrated holistic personalized medicine.
Most of the progress in cardiac energetics in recent years has been spurred by the pressure-volume area concept, the natural extension into energetics of earlier pioneering work delineating the time-varying elastance framework for ventricular contraction. The book draws together a broad spectrum of researchers - basic, applied and clinical - having a shared interest in the energetics of cardiac muscle and ventricle, providing an overview of the current state of the art.
The problem of the long-term proliferation of cells is a seminal one. It has always been a hot subject in biology, a source of far-reaching hypotheses, even more so now when explanations for the mechanisms of cell prolifera tive mortality or immortality seem within our reach. A question which is still debated is whether an infinite division potential can be a normal trait or is always the result of modifications leading to abnormal cell growth and escape from homeostasis. In general, investigators have been advocates of one of the two extremes, universal limited or unlim ited normal proliferative potential. Since the long-term proliferative potential of cells concerns regulation of development, regeneration of tissues, and homeostatic control of cell growth, in brief survival of living organisms, and since the regulation of these processes is so different along the evolutionary scale, it is not surpris ing that there does not seem to be any universal trait. The question of whether cells are endowed with finite or infinite prolifera tive phenotypes has to be seen using the perspective of comparative biology."
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.
Regeneration, the homeostatic ability to maintain tissue structure in the face of normal cell turnover or loss of tissue damaged by trauma or disease, is an essentialdevelopmental process that continues throughout life. As recently as a decade ago, any serious discussion of the possibility of regeneration becoming a practical medical tool in the near future had the air of science fiction or over-optimistic speculation. The term regenerative medicine was certainly on many lips but few actually expected to soon see it applied in a clinical setting. A tidal wave of discovery has changed that and investigating the cellular mechanisms of natural regeneration has become one of the hottest topics in developmental biology and biomedicine in general. Many researchers entering the field find that the regeneration literature is still quite diffuse perhaps owing to the disparate biological systems that have been the object of study including hydra, planaria, newts, axolotls and more recently several mouse strains. The volume editors believe that an attempt to organize or systematize the literature is long overdue. In this volume, respected experts highlight the latest findings in vertebrate (including mammals) wound healing and regeneration. They present eleven reviews that cover a wide range of topics, from wound repair and its relationship to regeneration, through systems including lenticular, neural, and musculoskeletal tissues and limbs, to epigenetics and the role of the cell cycle. Nuclear reprogramming and cellular plasticity, which open the door for potential regenerative medical therapies for injury and degenerativedisease, are recurring themes throughout the book. We are all now part of the regeneration revolution."
This book addresses instruments, methodologies and diagnostic methods used to evaluate and diagnose human movement, locomotion and physical status in general. Starting from historical perspective, the idea of understanding human locomotion by applying technical measurement devices and incorporating measurement data into physical representation of gross body movement is presented and explained, an approach known as inverse dynamics. With this approach as a kind of umbrella concept, components of measurement systems including relevant signal and data processing methods are described. Modern instruments to capture body movement by measuring its kinematics, kinetics and surface electromyography (sEMG) are thus described; all systems being used dominantly-if not exclusively-in a movement analysis laboratory setting. Focusing mainly on human posture and gait, but including also examples of movement patterns from selected kinesiological and sports activities, the book attempts to present essentials of biomechanics and biomedical engineering approach to this subject matter. It illustrates how data collected and elaborated by modern engineering technology can complement traditional expert knowledge of a kinesiologist or a medical doctor. The book is applicable in the fields of sports, physical activities, as well as in medical diagnostics and rehabilitation. The examples of this book's practical application might be in evaluation of efficiency of human gait, in evaluation of skeletal muscle fatigue in physical exercise, in biomechanical diagnostics of traumatological conditions requiring orthopaedic treatment and the like. This book can also be used in planning and executing research endeavours, particularly in a clinical context as a reference for various diagnostics procedures. It presents the lecture notes of a course carrying the same name within Medical Studies in English at the University of Zagreb for more than a decade. |
