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.

There's a silent epidemic in western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Modern orthodontics has persuaded us that braces and oral devices can correct these problems. While teeth can certainly be straightened, what about the underlying causes of this rapid shift in oral evolution and the health risks posed by obstructed airways? Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis, as well as a major alternative to orthodontics that promises more significant long-term relief. Jaws will change your life. Every parent should read this book.

The volume raises attention to the need of a completely new approach to breast cancer based on the knowledge collected on early breast cancer in the past two decades. The chapters are contributed by experts of all the fields participating in the clinical research and care of breast cancer. The practical importance of such a book is underlined by the increasing number of breast cancer cases, and also the increasing proportion of early stage-cases. The ultimate goal of the book is to point to the heterogeneous nature of the disease which is more striking and has more importance in care at the very early stages than at the more advanced stages. The book recommends the utilization of all the information provided by multimodality imaging and special pathological methods, a new classification system and therapeutic guidelines since early breast cancers should not be treated based on experience obtained with palpable tumors. No similar book has been yet released to the market. The book is written for all the members of the team participating in the diagnosis and treatment of breast cancer (radiologists, pathologists, surgeons, clinical and radiation oncologists), but may be useful for medical students and residents too. The chapters are illustrated with didactic pictures, and special emphasis is given to provide a peep into the practice of the special procedures for the careful examination and individualized therapy of each case.

How do our muscles produce energy for exercise and what are the underlying biochemical principles involved? These are questions that students need to be able to answer when studying for a number of sport related degrees. This can prove to be a difficult task for those with a relatively limited scientific background. "Biochemistry for Sport and Exercise Metabolism" addresses this problem by placing the primary emphasis on sport, and describing the relevant biochemistry within this context.

The book opens with some basic information on the subject, including an overview of energy metabolism, some key aspects of skeletal muscle structure and function, and some simple biochemical concepts. It continues by looking at the three macromolecules which provide energy and structure to skeletal muscle - carbohydrates, lipids, and protein. The last section moves beyond biochemistry to examine key aspects of metabolism - the regulation of energy production and storage. Beginning with a chapter on basic principles of regulation of metabolism it continues by exploring how metabolism is influenced during high-intensity, prolonged, and intermittent exercise by intensity, duration, and nutrition.

Key Features: A clearly written, well presented introduction to the biochemistry of muscle metabolism.Focuses on sport to describe the relevant biochemistry within this context.In full colour throughout, it includes numerous illustrations, together with learning objectives and key points to reinforce learning.

"Biochemistry for Sport and Exercise Metabolism" will prove invaluable to students across a range of sport-related courses, who need to get to grips with how exercise mode, intensity, duration, training status and nutritional status can all affect the regulation of energy producing pathways and, more important, apply this understanding to develop training and nutrition programmes to maximise athletic performance.

Infants and children spend one- to two-thirds of their life asleep. Despite this, very little attention has been paid to understanding both normal sleep and sleep-related abnormalities during child development. This volume is devoted to breathing during sleep, its changes with development (from the fetus onwards), and the pathophysiology of sleep-related breathing disorders. Sleep and Breathing in Children: investigates breathing during sleep from the fetus onwards examines the effects of sleep on upper airway resistance, ventilatory drive, and respiratory muscle tone compares differences between childhood and adult obstructive sleep apnea, and the profound changes in breathing and sleep during growth and maturation discusses the current research within the field of pediatric sleep disorders reviews the history of childhood obstructive sleep apnea syndrome, and outlines a future framework for the study of childhood sleep-disordered breathing

Physiology and Pharmacology of the heart integrates the basic sciences with clinical medicine. The book is heavily illustrated to clarify the concepts, and contains a glossary of terms and a brief listing of the important drugs.

Robert Provine boldly goes where other scientists seldom tread-in search of hiccups, coughs, yawns, sneezes, and other lowly, undignified human behaviors. Upon investigation, these instinctive acts bear the imprint of our evolutionary origins and can be uniquely valuable tools for understanding how the human brain works and what makes us different from other species. Many activities showcased in Curious Behavior are contagious, but none surpasses yawning in this regard-just reading the word can make one succumb. Though we often take it as a sign of sleepiness or boredom, yawning holds clues to the development of our sociality and ability to empathize with others. Its inescapable transmission reminds us that we are sometimes unaware, neurologically programmed beasts of the herd. Other neglected behaviors yield similar revelations. Tickling, we learn, may be the key to programming personhood into robots. Coughing comes in musical, medical, and social varieties. Farting and belching have import for the evolution of human speech. And prenatal behavior is offered as the strangest exhibit of all, defying postnatal logic in every way. Our earthiest acts define Homo sapiens as much as language, bipedalism, tool use, and other more studied characteristics. As Provine guides us through peculiarities right under our noses, he beckons us to follow with self-experiments: tickling our own feet, keeping a log of when we laugh, and attempting to suppress yawns and sneezes. Such humble investigations provide fodder for grade school science projects as well as doctoral dissertations. Small Science can yield big rewards.

The "New York Times" bestseller - with a new afterword about early specialization in youth sports.
The debate is as old as physical competition. Are stars like Usain Bolt, Michael Phelps, and Serena Williams genetic freaks put on Earth to dominate their respective sports? Or are they simply normal people who overcame their biological limits through sheer force of will and obsessive training?
In this controversial and engaging exploration of athletic success and the so-called 10,000-hour rule, David Epstein tackles the great nature vs. nurture debate and traces how far science has come in solving it. Through on-the-ground reporting from below the equator and above the Arctic Circle, revealing conversations with leading scientists and Olympic champions, and interviews with athletes who have rare genetic mutations or physical traits, Epstein forces us to rethink the very nature of athleticism.

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 the Nervous System, Taurine in the Immune System, Taurine and Diabetes, and Taurine and the Cardiovascular System. 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.

Very Short Introductions: Brilliant, Sharp, Inspiring Physiology is the science of life, and sets out to understand how living things work and what makes them distinct from the non-living. It considers how our bodies are supplied with energy, how they maintain their internal parameters, the ways in which we gather and process information, the ways we take action, and the creation of new generations. This Very Short Introduction explores the field of human physiology, considering how the body works, senses, reacts, and defends itself. As Jamie A. Davies shows, human life (and indeed, all life) is sustained by the interplay of a wide variety of physiological mechanisms and principles. He discusses the physiological experiments and research undertaken to understand these processes, and analyses the ethical issues involved. He also considers the evolution of the scientific field itself, showing how enhanced understandings of physiological knowledge can help inform medical research and care. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

In this book, physics in its many aspects (thermodynamics, mechanics, electricity, fluid dynamics) is the guiding light on a fascinating journey through biological systems, providing ideas, examples and stimulating reflections for undergraduate physics, chemistry and life-science students, as well as for anyone interested in the frontiers between physics and biology. Rather than introducing a lot of new information, it encourages young students to use their recently acquired knowledge to start seeing the physics behind the biology. As an undergraduate textbook in introductory biophysics, it includes the necessary background and tools, including exercises and appendices, to form a progressive course. In this case, the chapters can be used in the order proposed, possibly split between two semesters. The book is also an absorbing read for researchers in the life sciences who wish to refresh or go deeper into the physics concepts gleaned in their early years of scientific training. Less physics-oriented readers might want to skip the first chapter, as well as all the "gray boxes" containing the more formal developments, and create their own a-la-carte menu of chapters.

Three-dimensional scoliosis therapy has for decades played an established role in the conservative management of mild and even of severe scoliosis. As well as describing every aspect of the pathologically curved, deformed spine, this textbook incorporates an extensive programme of exercises that can be tailored specifically to the needs of the individual patient. As outlined in Three-Dimensional Scoliosis Therapy: The Schroth Breathing Orthopaedic System, correction of the spinal deformity is based on a special breathing technique and active muscle stretching, as well as on elongation, detorsion and reduction of lordosis. The provision of psychological support for the patient is also emphasised as a key element. Christa Lehnert-Schroth born 1924 in Meissen She worked as a physiotherapist for about 50 years with scoliosis patients and further developed her mother's breathing orthopaedic technique with great success. Between 1961 and 1995 Christa Lehnert-Schroth - always surrounded by physicians - was director of the private Katharina-Schroth-Klinik in Bad Sobernheim/Germany. In many lectures, articles, seminars and films for physiotherapists and medical doctors in addition to recorded discs for patient's training at home she illustrated her mother's special method for scoliosis assuring well being of many patients and in honor her mother's legacy.

Pressure-related chronic wounds are an important health concern that affects millions of patients and accumulates billions in annual costs. These wounds may occur when soft tissues are mechanically compressed between bony prominences and a supporting surface. This book gives a complete and quantitative explanation of the mechanobiology which causes chronic wounds. The reviews give an overall picture on all length scales of the phenomenon, starting from musculoskeletal biomechanics to the modeling of soft tissues and their interaction with bones. At the microscopic levels, it thoroughly reviews experiments and modeling of cellular forces and molecular processes that occur during injury and healing, including the integrity of living cells subjected to sustained mechanical forces and deformations. The results allow a complete picture of the tolerance of human tissues to sustained loads, and an understanding of the risk for onset of chronic wounds. Hence, this book is also valuable for all professionals involved in the prevention and treatment of chronic wounds.
