Hundreds of questions you'd only ask your doctor after your third martini! You know how it is... you're at a party, you've had a drink or two, and then someone introduces you to a friend. He's a doctor. And it seems like the perfect time to ask all those strange questions you've always wondered about, but never had the courage to ask: Can poppy seeds make you test positive for heroin? What are goosebumps? Why does asparagus make your wee smell? Why do old people get hairy ears? Is it possible to lose your contact lenses inside your head forever? Why do some people have an "outie" belly button and some people an "innie"? Does warm milk really help you sleep? Is it actually possible to get scared to death? This book gives the answer to these and many more questions - pretty much everything you've ever wanted to know - but never had enough Dutch courage to ask!
This study asserts that cellular and intracellular membranes are active in every aspect of the body's physiology and pathophysiology. It compares secondary through to quaternary structures and protien sequences and guages their influence on health, disease and drug therapy. The book highlights the importance of correlations, homologies and categorizing multifunctionality by domain and complex.
Melatonin is a powerful hormone and antioxidant with numerous effects on the metabolism and the health of humans. Available as a dietary supplement in the United States since 1993, it is one of the most popular over-the-counter alternative remedies available. Comprising contributions from researchers who have studied the role of melatonin in various disease and physiological states, Melatonin in the Promotion of Health, Second Edition provides a wide variety of expert reviews on the biology of melatonin relevant to health. Beginning with a history of melatonin and its relation to circadian rhythms, the book examines its use in a host of applications, including: Gut motility and gastrointestinal diseases Anesthesia and surgery Bone health Breast cancer Cardiovascular diseases Diabetes Age-related macular degeneration and uveitis Melanoma, solar skin damage, and collagen synthesis The prevention of DNA damage Mental disorders, sleep, and issues related to jet lag and shift work The data gathered from a large number of carefully controlled animal and human studies have clearly implicated melatonin in the control mechanisms of a wide variety of physiological and psychological activities, making it a potent candidate for therapeutic use in the treatment of a diverse range of diseases. This volume demonstrates that continued studies of this molecule raise the exciting prospect of providing new avenues of treating numerous diseases more effectively and with less side-effects than those found in conventional treatment modalities.
The main focus of this book is on brown adipose tissue and its metabolic function. The book provides a timely update on the latest research and shows where the field is heading. Brown adipose tissue (BAT) dissipates energy and has received considerable attention in the last few years, having been re-discovered in adult humans in 2007/9. Moreover, BAT might offer a target for novel therapies to address obesity, a health condition that has reached pandemic dimensions.
Chronic disease states of aging should be viewed through the prism of metabolism and biophysical processes at all levels of physiological organization present in the human body. The first volumeconnects these insights to what causes them to go awry in the context of unhealthy human behaviors and aging, aiming to buttress scientific creativity. It also provides links between the art and science of medicine that strengthens problem-solving in patient care. New and important discoveries in the area of metabolic health and metabolic diseases are discussed in exquisite detail. The second volume describes the building blocks of understanding from a reasonable but not high-level technical language viewpoint, employing the perspective of a clinical physician. It brings together concepts from five specific branches of physics relevant to biology and medicine, namely, biophysics, classical electromagnetism, thermodynamics, systems biology and quantum mechanics.
The adipokines (also called adipocytokines), are a group of peptides secreted by adipose tissue. They have diverse roles, from the cell to the whole body. The book is designed for health scientists, doctors, physiologists, immunologists, biochemists, college and university teachers and lecturers, undergraduates and graduates. The chapters are written either by experts or specialists in their field.
Channels and transporters are multi-functional proteins that mediate substrate transport and signal transmission and simultaneously act as regulators for other proteins and biosensors for environmental materials. Patch clamping is an epoch-making technique that allows researchers to perform real-time measurements of electrogenic channel/transporter functions at the single/multiple molecular level. This book describes not only the conventional patch clamp techniques but also their newly developed variations or applications, such as perforated patch, slice patch, blind patch, in vivo patch, imaging patch, smart patch, and automated patch clamping. These patch clamp techniques are now essential and are extensively used across the life sciences and in related industries. With plain and practical descriptions of patch clamping and how to carry it out, especially for beginners, the book also shows how widely and exquisitely the patch clamp techniques can be applied by expert electrophysiologists. This work serves as a useful guide for young researchers and students in training and laboratory courses as well as for senior researchers who wish to extend their repertoire of techniques.
Humans possess a remarkable ability to extract rich three-dimensional information about sound environments simply by analyzing the acoustic signals they receive at their two ears. Research in spatial hearing has evolved from a theoretical discipline studying the basic mechanisms of hearing to a technical discipline focused on designing and implementing increasingly sophisticated spatial auditory display systems. This book contains 39 chapters representing the current state-of-the-art in spatial audio research selected from papers presented in Sendai, Japan, at the First International Workshop on the Principles and Applications of Spatial Hearing.
Swallowing difficulty or dysphagia is a common disorder and affects all age groups from the newborn to the elderly. Several medical conditions like lack of dentition, gastroesophageal reflux disease, eosinophilic esophagitis, cardiomegaly and strokes can cause dysphagia. It can also follow head -neck surgeries. It is important to diagnose and treat dysphagia, otherwise it can lead to malnutrition and dehydration. Improved understanding of the physiology of swallowing, advances in endoscopic and radiological techniques along with an increasing elderly population has resulted in development of a separate swallowing disorders discipline. This book would be an aid for clinicians, educators and trainees from the fields of speech language pathology, pediatrics, otolaryngology, gastroenterology, oncology, neurology, geriatrics and rehabilitation, all of who form a part of the multidisciplinary swallowing team.
A handbook for how we can use the power of our hormones to master any stage of life. Joint pain, weight gain, migraines, acne, sleepless nights, loss of libido - all of these and more can be caused by hormone imbalances. Our health is impacted by our hormones all the way through our lives. So why do we often assume they're mainly 'a menopause thing', and wait until hot flushes arrive before we take them seriously? The truth is that many women find that their hormone-related symptoms aren't acknowledged, despite the impact they can have, years before menopause hits, on almost every aspect of their lives. With advances in medical science, however, effective new treatment options are available, including modern hormone replacement therapy (HRT), diet, and exercise. So why don't more of us know that help is at hand? Why are we still being told that we have to put up with these conditions? Our Hormones, Our Health is written by two doctors who draw on their experience as practitioners, and as women. With the aid of pioneering research from epigenetics, stress medicine, nutritional medicine, and modern HRT, they show us how women can live with health and happiness - no matter what their age.
The human brain represents about 2% of the body weight, yet it accounts for approximately 20% of aerobic metabolism. This high dependency on energy-consuming processes is mainly caused by the active transport of ions, which is necessary to compensate for the transmembrane ion currents that are part ofthe complex signaling processes in the brain. Ninety-five percent ofthe brain's ATP is derived from mitochondrial oxidative phosphorylation. Since that organ' s storage capacity for oxygen is minimal, any interruption of oxygen delivery to brain cells willlead to changes in membrane excitability and, there fore, to disruption of neuronal signaling within seconds. It seems that mamma lian brain is especially vulnerable to such an interruption, since oxygen deprivation leads to activation of ion channel mechanisms in neurons that impair their communications. Thus, the function of the brain as a coordinator of vital homeostatic reflexes, and complex body reactions to external challenges, depends critically on the rate of oxygen delivery and oxygen consumption. Oxygen delivery depends on two variables described in the Fick relation ship: volume flow rate ofblood and the arterial oxygen content. A reduction in either of these two variables will have serious effects on vital brain func tions. Reduction of arterial blood flow to the brain can be caused by cardiac arrest, shock, carotid occlusion, Of hypotension (global ischemia). Oxygen content is progressively decreased in asphyxia (including drowning)."
In the historical record there is abundant evidence that obesity was a medical and health concern as long as medicine has been practiced. The idea of diet and exercise are bulwarks in the fight against obesity in history from the time of Hippocrates to the 16th century--a span of 2,000 years. However, our scientific understanding of this problem is only a little over 200 years old. An examination of the root cause of what many consider the obesity epidemic, A Guide to Obesity and the Metabolic Syndrome traces the origins and types of obesity and its treatment. Examining in detail the developing treatment for obesity, this book provides: * A history of obesity, including treatment, proposed causes, and perceptions * An examination of the causes and problems associated with obesity * A discussion of lifestyle, diet, exercise, and treatment strategies * A detailed look at the medications and surgeries available for obesity The fact that we have an epidemic of obesity today that is covering the globe suggests that the strategically simple ideas of eating less and exercising more, ideas that require commitment and personal involvement by the individual, have not been very successful. As we move forward in trying to understand this problem, we need to be alert to strategies and tactics that may not require individual motivation and commitment--history has shown that they do not work well. This book supplies guidance on developing and designing novel strategic interventions against obesity and metabolic disorders.
Ion channels play a vital role in basic physiological functions such as generation of electrical activity in nerves and muscle, control of cardiac excitability, intracellular signaling, hormone secretion, cell proliferation and many other biological processes. Because of their prevalence and the critical role they play in virtually all tissue types and organs, ion channels are also involved in a number of pathophysiological conditions. The aim of this volume is to review recent advances in the field of ion channel related diseases. Following an overview chapter summarizing the current state of ion channel screening technologies, five topics covering areas such as cancer, cardiac arrhythmias, cystic fibrosis, and pain have been selected, and the current state of knowledge is presented by leading experts in their field. Each chapter is structured to cover the biological rationale for the target, the current status in the development of agents to treat the disease, and future prospects and challenges facing each therapeutic area. The reader will receive a critical overview covering the progress made in the rapidly developing and complex field of ion channels and diseases.
Atrial Fibrillation from an Engineering Perspective provides an up-to-date overview of techniques developed for acquisition, modeling, and analysis of noninvasive, bioelectrical signals reflecting this common arrhythmia. Special emphasis is put on emerging technologies for monitoring of atrial fibrillation in connection with ischemic stroke, interventional ablation procedures, and pharmacological treatment, applications which all depend on the availability of techniques for detecting and characterizing episodes of paroxysmal atrial fibrillation. Detectors exploring both rhythm and morphology are described, as well as detectors confined to rhythm and better suited for low power implementation. A wide variety of approaches to modeling and characterization of atrial activity are described, emanating from a statistical and deterministic starting points. This book is suitable for graduate students, researchers, and engineers who want a comprehensive treatise of atrial fibrillation from an engineering perspective. It may be used for self-study, as a supplement to courses in signal processing, or as a modern monograph by researchers in the field of atrial fibrillation.
As nutrition research is shifting its focus from epidemiology and physiology to effects of nutrients at the molecular level, a uniquely tailored diet that corresponds to the demands of our genetic signature is emerging as an indispensable need. Using high-throughput genomic tools, nutrigenomics unravels the influence of micro- and macronutrients as potent dietary signals regulating metabolic pathways and unmasks how susceptible genotypes are predisposed to diet-related diseases. Selected topics from this field have been covered in some books, but no other comprehensive text on epigenetics, nutrition, and human health and disease is available, until now. This book illustrates nutrition's influence on epigenetic inheritance and the mechanisms underlying the modification of the metabolic imprint of an individual. This enriched understanding of nutrigenomics can be applied to master a tailored diet that can alleviate imprinted metabolic syndromes. Specifically, the book focuses on: * Maternal, perinatal, and neonatal nutrition * Epigenetic mechanisms and cancer * Impacts of dietary factors, folate deficiency and DNA methylation * Nutrition's influence on genetic imprinting * The basics of nutrigenomics and epigenetic regulation

Vasopressin is a hormone which has an increasingly important profile. Not only does it play a physiologically significant role in renal water regulation but it also has other renal actions and plays a role in overall cardiovascular control. Even more interesting is the recent growing interest in its potential effects on the brain, notably its influence on specific behaviours. This monograph about the polypeptide vasopressin covers all aspects relating to the production, control of release, and actions of this molecule within the body, including its roles as a hormone and as a central neurotransmitter. A consideration of the evolution of the molecule across the species and a brief historical perspective are also included. Clinical conditions associated with hypo- and hyper-production states are considered together with aspects of treatment, in addition to other clinical correlates.
An Introduction to Cardiovascular Physiology provides the student with the key concepts of cardiovascular physiology, from the fundamentals of how the cardiovascular system works in both health and disease, through to a consideration of more complex physiological mechanisms. This brand new companion work Cardiovascular Physiology: Questions for Self-Assessment allows students to test themselves on all aspects of the topic with over 200 questions and answers, at a pace to suit their learning. Questions follow An Introduction to Cardiovascular Physiology's table of contents, and the author has set at least one question on each chapter's learning objective to help the student to assess their progress against the set objectives. The questions are designed to test basic understanding, fundamental principles and medical relevance, and they avoid excessive detail. Most are in a multiple choice, True/False format, with a sprinkling of other question styles including extended matching questions, where the reader chooses the best answer from a list, and testing little numerical problems. Also included with the answers are 'More information' boxes that include a brief explanation, and links to relevant information and figures from a range of chapters, thus encouraging integration of learning across the subject.
