Excitable media comprise a class of models for a wide range of physical, chemical, and biological systems that exhibit spontaneous formation of spatial patterns. Patterns in Excitable Media: Genesis, Dynamics, and Control explores several aspects of the dynamics of such patterns-in particular their evolution upon interaction with structural and functional heterogeneities in the system. The book provides readers with an introduction to recent developments in the interdisciplinary field of dynamics and control of patterns in nonlinear biological systems described by excitable media models. It also discusses low-amplitude control schemes for eliminating such patterns from an excitable medium which has direct clinical relevance in view of the close connection to life-threatening cardiac arrhythmia.
Mechanical stress is vital to the functioning of the body, especially for tissues such as bone, muscle, heart, and vessels. It is well known that astronauts and bedridden patients suffer muscle and bone loss from lack of use. Even the heart, in pumping blood, causes mechanical stress to itself and to vascular tissue. With the loss of mechanical stress, homeostasis becomes impaired and leads to pathological conditions such as osteopenia, muscle atrophy, and vascular tissue dysfunction. In elderly populations, such mechanical pathophysiology, as well as the mechanical activities of locomotor and cardiovascular systems, is important because skeletal and heart functions decline and cause diseases in other organs. In this monograph, mechanical stress is discussed by experts in the field with respect to molecular, cellular, and tissue aspects in relation to medicine. Covering topics such as gravity and tissues and disuse osteoporosis, the book provides the most up-to-date information on cutting-edge advancements in the field of mechanobiology and is a timely contribution to research into locomotor and circulatory diseases that are major problems in contemporary society.
This manual contains extensive discussions on clinical topics and disorders and helps students apply the concepts of anatomy and physiology to their daily life and is especially valuable for students who are planning careers in the health professions.
This volume contains the Proceedings of the XVIIth ISAC Meeting held in Valladolid, Spain, July 1-5, 2008. As such, it contains the most permanent records of the combined efforts of all attendants. The meeting was held at the School of Medicine of Valladolid, that had the privilege of a recent celebration. The celeb- tion was none other than its 600th anniversary, implying that all participants were surrounded by historical landmarks, from the historical building of the University, to the Museum of polychrome sculpture of Valladolid, to the Monastery of Clarisas in Tordesillas, to the beauty and charm of Salamanca. In this ambience we had three days of intense work, distributed in several oral sessions, preceded by plenary lectures given by our invited speakers who were kind enough to provide us with the latestprogressintheirspeci c elds. We also hadtimeallottedtoposterviewing. As regularattendantsto the XVIIth ISACMeeting, we want to expressourappreciation forthevaluablediscussionssurroundingeachposter,theenthusiasticpresentationof data, the comments of colleagues with suggestions for improvement, and the plans for collaborations that emerged from these discussions. Needless to say that XVIIth ISAC Meeting was the fruit of many collabo- tive efforts. The Local Organizing Committee pro ted from the advice of several colleagues from around the world, namely, Prof. Chris Peers from Leeds, UK, Prof. Prem Kumar from Birmingham, UK, Prof. Nanduri Prabhakar from Chicago, USA, Prof. Colin Nurse from Hamilton, Canada, and Prof. Rodrigo Iturriaga from Santiago, Chile.
Molecular Aspects of Aging: Understanding Lung Aging covers recent research in the mechanisms that contribute to cellular senescence. Covering universal themes in aging, such as the exhaustion of stem cells and subsequent loss of the regenerative refueling of organs as well as immunosenescence, this text illuminates new directions for research not yet explored in the still poorly investigated area of molecular mechanisms of lung aging. The molecular nature of general aging processes is explored with targeted coverage on how to analyze lung aging through experimental approaches.
This book contains the edited version of invited lectures presented at the IUTAM Symposium on Synthesis in Bio Solid Mechanics held in Copenhagen, Denmark, 24-27 May, 1998. The Symposium was attended by 48 scientists in mechanics, mathematics and medicine from 14 countries. The fields of interest range over experimental issues, models of bone remodelling, micromechanics of bone, analogies between optimal design models and bone remodelling, to mathematical issues of the various models seen in this exciting area. Biomechanics has been a very active research area in the last 25 years and covers a very broad class of problems. The present book concentrates on the solid mechanics domain of biomechanics, where important problems of synthesis are presently an active and challenging part. Characteristics of biomechanical materials are not only their inhomogeneity and anisotropy, but also their capability to change in relation to actual use. These living materials call for new methods of analysis and also new methods for synthesis. By synthesis in this context is meant design of implants or artificial control of material growth. Bone mechanics is closely related to recent work on analysis and design of microstructural anistropic materials. Also, recent work in shape design can to some extent be useful in the more complicated problems of biomechanics. Here interface problems play an essential role. This volume will be of interest to researchers in the field of (bio)mechanics and (bio)materials.

Despite major efforts by the scientific community over the years, our understanding of the pathogenesis or the mechanisms of injury of multiple sclerosis is still limited. Consequently, the current strategies for treatment and management of patients are limited in their efficacy. The mechanisms of tissue protection and repair are probably even less understood. One reason for these limitations is the enormous complexity of the disease and every facet of its pathogenesis, the mechanisms of tissue injury, the diagnostic procedures and finally the efficacy of treatments and their side effects. The aim of this book is to review the most recent advances made in this highly complex field.
A timely symposium entitled Body-Fluid Homeostasis: Transduction and Integration was held at Araraquara, Sao Paulo, Brazil in 2011. This meeting was convened as an official satellite of a joint gathering of the International Society for Autonomic Neuroscience (ISAN) and the American Autonomic Society (AAS) held in Buzios, Rio de Janeiro. Broad international participation at this event generated stimulating discussion among the invited speakers, leading to the publication of Neurobiology of Body Fluid Homeostasis: Transduction and Integration. Drawn from the proceedings and filled with rich examples of integrative neurobiology and regulatory physiology, this volume: Provides updated research using human and animal models for the control of bodily fluids, thirst, and salt appetite Explores neural and endocrine control of body fluid balance, arterial pressure, thermoregulation, and ingestive behavior Discusses recent developments in molecular genetics, cell biology, and behavioral plasticity Reviews key aspects of brain serotonin and steroid and peptide control of fluid consumption and arterial pressure The book highlights research conducted by leading scientists on signal transduction and sensory afferent mechanisms, molecular genetics, perinatal and adult long-term influences on regulation, central neural integrative circuitry, and autonomic/neuroendocrine effector systems. The findings discussed by the learned contributors are relevant for a basic understanding of disorders such as heat injury, hypertension, and excess salt intake. A unique reference on the neurobiology of body fluid homeostasis, this volume is certain to fuel additional research and stimulate further debate on the topic.

Taurine 8 represents the combined efforts of investigators on the roles of the amino acid taurine on human health and disease. The chapters covered in this book are directly derived from presentations of the contributors at the 18th International Taurine Meeting held in Marrakech, Morocco in April 2012. The purpose of this book is to disseminate current findings on taurine's contribution in several organ systems. This book covers the following topics: Taurine in Nutrition and Metabolism, the Protective Role of Taurine, and the Role of Taurine in Reproduction, Development, and Differentiation. Dr. Abdeslem El Idrissi, College of Staten Island and Dr. William L'Amoreaux, College of Staten Island, were co-chairs of the Organizing Committee for the meeting. Data presented at this meeting provided compelling evidence that taurine is not only cytoprotective in cardiomyocytes, but also is a potent GABA agonist, whereby it can facilitate vasodilation of conducting arteries. Taurine conjugates, such as taurine chloramine, may protect cells from oxidative stress via increased HO-1 expression. In adult rodents, taurine has a potent effect on plasma glucose levels, likely through the release of insulin in pancreatic beta cells. As a potential neurotransmitter, taurine is known to work via the GABAergic system, but current research presented at this meeting suggest that taurine may interact with glutamate and serotonin receptors as well. Data are also presented to demonstrate the protective roles of taurine on neurons in neuroblastoma. Perhaps the most important and exciting presentation is the role of taurine and alcohol: the combination may be lethal. Data are also presented at this meeting of the potential role taurine may have as an adjuvant treatment with cisplatin in chemotherapy.

Several milestones in biology have been achieved since the first publication of the Handbook of Molecular and Cellular Methods in Biology and Medicine. This is true particularly with respect to genome-level sequencing of higher eukaryotes, the invention of DNA microarray technology, advances in bioinformatics, and the development of RNAi technology. Now in its third edition, this volume provides researchers with an updated tool kit that incorporates conventional as well as modern approaches to tackle biological and medicinal research in the post-genomics era. Significantly revised to address these recent changes, the editors have evaluated, revised, and sometimes replaced protocols with more efficient, more reliable, or simpler ones. The book has also been reorganized with section headings focusing on different biological levels connected to one another, taking into account the central dogma of biology (DNA RNA protein metabolites). The book first explores traditional approaches and then moves to the modern "omics" approaches, including genomics, proteomics, and metabolomics. It also discusses the manipulation of biological systems (including RNAi) and macromolecular analyses, focusing on the use of microscopy. In each chapter, various notes and cautionary considerations are presented for potentially hazardous reagents. Filled with diagrams, tables, and figures to clarify methods, most chapters also contain Troubleshooting Guides indicating problems, possible causes, and solutions that may be incurred in carrying out the procedures. Researchers and scientists who master the techniques in this book are putting themselves at the cutting edge of biological and medicinal research.
Currently, the health of over half the adult population in the UK suffers because of fat. The UK is not alone: obesity is a global problem, but the populations of some countries are heavier than others. This book probes the chemistry of fat in our bodies, providing a unique insight into understanding obesity, and how this material becomes accumulated to cause obesity with particular emphasis on the contribution of nutrition beyond calories. It visits the current hot topic of the genetic origins of obesity and progresses through to the relatively under publicised field of epigenetics, emphasising its importance to understanding the current epidemic. Coming in the wake of the establishment of international collaborations, the book aims to quantify the extent of the contribution of nutritional deficiencies to body weight gain. Yet even before these studies begin some important links have been identified and the molecular mechanisms by which they induce obesity have been mapped. This information reveals a serious problem for the next generation, but it is expected to provide the necessary information to tackle the obesity epidemic. Based on an extensive review of scientific literature, this topical book is written in a way that is accessible to the non-specialist. Suitable for the general public, the principal focus of the book is to advance the public understanding and awareness of science through the high interest subject of obesity. However, many universities recommend public understanding of science texts to students as a means of broadening general knowledge and as a means to emphasise to students the importance of communicating their research to the public. This book will be instrumental in developing this knowledge.
Science is a force for good in the world-at least usually. But sometimes, when obsession gets the better of scientists, they twist a noble pursuit into something sinister. Under this spell, knowledge isn't everything, it's the only thing-no matter the cost. Bestselling author Sam Kean tells the true story of what happens when unfettered ambition pushes otherwise rational men and women to cross the line in the name of science, trampling ethical boundaries and often committing crimes in the process. The Icepick Surgeon masterfully guides the reader across two thousand years of history, beginning with Cleopatra's dark deeds in ancient Egypt. The book reveals the origins of much of modern science in the transatlantic slave trade of the 1700s, as well as Thomas Edison's mercenary support of the electric chair and the warped logic of the spies who infiltrated the Manhattan Project. But the sins of science aren't all safely buried in the past. Many of them, Kean reminds us, still affect us today. We can draw direct lines from the medical abuses of Tuskegee and Nazi Germany to current vaccine hesitancy, and connect icepick lobotomies from the 1950s to the contemporary failings of mental-health care. Kean even takes us into the future, when advanced computers and genetic engineering could unleash whole new ways to do one another wrong. Unflinching, and exhilarating to the last page, The Icepick Surgeon fuses the drama of scientific discovery with the illicit thrill of a true-crime tale. With his trademark wit and precision, Kean shows that, while science has done more good than harm in the world, rogue scientists do exist, and when we sacrifice morals for progress, we often end up with neither.
As anyone who takes up a new sport quickly discovers, even basic athletic moves require high levels of coordination and control. Whether dribbling a basketball or hitting a backhand, limbs must be synchronized and bodies balanced, all with precise timing. But no matter how diligently we watch the pros or practice ourselves, the body's inner workings remain invisible. The Hidden Mechanics of Exercise reveals the microworld of the human body in motion, from the motor proteins that produce force, to the signaling molecules that activate muscles, to the enzymes that extract energy from nutrients. Christopher Gillen describes how biomolecules such as myosin, collagen, hemoglobin, and creatine kinase power our athletic movements. During exercise, these molecules dynamically morph into different shapes, causing muscles, tendons, blood, and other tissues to perform their vital functions. Gillen explores a wide array of topics, from how genetic testing may soon help athletes train more effectively, to how physiological differences between women and men influence nutrition. The Hidden Mechanics of Exercise tackles questions athletes routinely ask. What should we ingest before and during a race? How does a hard workout trigger changes in our muscles? Why does exercise make us feel good? Athletes need not become biologists to race in a triathlon or carve turns on a snowboard. But Gillen, who has run ten ultramarathons, points out that athletes wishing to improve their performance will profit from a deeper understanding of the body's molecular mechanisms.

This monograph provides a comprehensive overview of the latest advances in the field of vasopressin and oxytocin. In the summer of 1997, scientists from over 20 countries congregated in Montreal for the 1997 World Congress of Neurohypophysial Hormones, a conference that united the fields of vasopressin, neurohypophysis, and oxytocin in a single joint meeting that gave rise to this book. The organization of a joint meeting was prompted by several developments. Specifically the molecular characterization of the vasopressin/oxytocin receptor family made it mandatory to adopt an integrated view and to discuss the vasopressin/oxytocin ligand/receptor family as a whole. To ensure emphasis on novelty, the conference focused on advances made in the late-1990s and also included important contributions by scientist that had not previously been associated with the vasopressin/oxytocin field.

Synthesizing coverage of sensation and reward into a comprehensive systems overview, Neurobiology of Sensation and Reward presents a cutting-edge and multidisciplinary approach to the interplay of sensory and reward processing in the brain. While over the past 70 years these areas have drifted apart, this book makes a case for reuniting sensation and reward by highlighting the important links and interface between the two. Emphasizing the role of reward in reinforcing behaviors, the book begins with an exploration of the history, ecology, and evolution of sensation and reward. Progressing through the five senses, contributors explore how the brain extracts information from sensory cues. The chapter authors examine how different animal species predict rewards, thereby integrating sensation and reward in learning, focusing on effects in anatomy, physiology, and behavior. Drawing on empirical research, contributors build on the themes of the book to present insights into the human sensory rewards of perfume, art, and music, setting the scene for further cross-disciplinary collaborations that bridge the neurobiological interface between sensation and reward.
As recent articles about "the graying of America" suggest, a demographic revolution is well underway. The number of people living into extreme old age is increasing dramatically. By the year 2050 one in five of the world's population, including the developing countries, will be 65 or older, a fact which presages profound medical, biological, philosophical, and political changes in the coming century. In Time of Our Lives, Tom Kirkwood unfolds some of the deepest mysteries of medical science while demolishing some of the most persistent misconceptions. He overturns the almost universally held belief that aging is either necessary or inevitable--it isn't--and debunks the idea that there exists a "death gene" that evolved to inhibit population growth. Instead, Kirkwood shows that we age because our genes, evolving at a time when life was "nasty, brutish, and short," placed little priority on the long-term maintenance of our bodies. With such knowledge, along with new insights from genome research, we can devise ways to target the root causes of aging and of age-related diseases such as Alzheimer's and osteoporosis. Expanding the thesis of the "disposable soma," developed over twenty years of research, Kirkwood makes sense of the evolution of aging, explains how aging occurs, and answers fundamental questions like why women live longer than men. He even considers the possibility that human beings will someday have greatly extended life spans or even be free from senescence altogether. Beautifully written by one of the world's pioneering researchers into the science of aging, Time of Our Lives is a clear, original and, above all, inspiring investigation of a process all of us experience but few of us understand. |
