Adaptation, Stress, and Prophylaxis


Book Description

This book deals with one of the fundamental problems in the fields of biology and medicine, i. e. , the problem of adaptation of an organism to its environment. Essentially, adaptive responses enable animals and man to perform new tasks imposed by the environment and also to achieve timely avoidance of damage from environmental factors. Such are the roles of the defense response, adaptational reactions to high altitude and maximal loads, immunogenetic responses, etc. The author rightly views adaptive responses of the organism as reactions involving natural prophylaxis of disease, although processes of adaptation can also have detrimental consequences under certain conditions. It is, thus, understandable that problems of adaptation increasingly concern biologists, physiologists, and phy sicians. A number of important points distinguish this treatise from others in the field. Most researchers concerned with individual adaptation of human and animal organisms pay major attention to the dynamics of the gradual development of adaptation, i. e. , to gradual learning of new skills, training for endurance of new loads, or accomodation to high altitude. In the present monograph, abundant original and cited material is devoted to another problem: What is the concrete mechanism by which a nonadapted organism lacking resistance to a given factor is transformed into an adapted and resistant organism? In answering this question, the author concentrates mainly on the molecular basis of the adaptation mechanism.




Stress Adaptation, Prophylaxis and Treatment


Book Description

Stress reaction is likely to play a crucial role in a variety of degenerative diseases including cancer and cardiovascular diseases. The process of stress adaptation may appear to be simple, but in reality this is a very complex process and we are only beginning to understand the mechanism of adaptation. In January, 1998, scientists from around the world assembled to discuss the potential applicability of the concept of stress adaptation in the clinical arena. This volume contains original research papers presented on this subject during the conference Stress Adaptation, Prophylaxis and Treatment held in Calcutta, India, and serves as an up-to-date source of information for scientists, as well as clinicians interested in applying the concept of stress adaptation to the cure of diseases.







Stress, Shock, and Adaptation in the Twentieth Century


Book Description

This edited volume explores the emergence of the stress concept and its ever-changing definitions; its uses in making novel linkages between disciplines such as ecology, physiology, psychology, psychiatry, public health, urban planning, architecture, and a range of social sciences; its application in a variety of sites such as the battlefield, workplace, clinic, hospital, and home; and the emergence of techniques of stress management in a variety of different socio-cultural and scientific locations. In short, this volume explores what happened when stress entered the discourse around modernity.




Adaptive Protection of the Heart


Book Description

Published in 1991: This book explores the possibilities of protecting the heart against stress and ischemia through adaptation to intermittent hypoxia or to mild, nondamaging stress exposure. These possibilities are based on studies that show an increase in the potency and efficiency of stress-limiting systems when subjected to repeated stress actions, adaptation to high altitude hypoxia, or adaptation to increased physical loads. Any stress reaction is coupled with an activation of central and local stress-limiting systems, such as GABA-ergic, opioidergic, and serotonergic systems in the brain, as well as antioxidants, prostaglandins, and adenosine in executory organs. The book also presents the use of metabolites of stress-limiting systems rather than adaptation as a means to prevent cardiac arrythmias. It also discusses genetically determined deficiencies of stress-limiting systems and their role in the etiology of stress-induced diseases. Cardiologists and researchers studying stress and its effect on cardiovascular systems will find this book extremely useful.




Antioxidants in Sport Nutrition


Book Description

The use of antioxidants in sports is controversial due to existing evidence that they both support and hinder athletic performance. Antioxidants in Sport Nutrition covers antioxidant use in the athlete ́s basic nutrition and discusses the controversies surrounding the usefulness of antioxidant supplementation. The book also stresses how antioxidants may affect immunity, health, and exercise performance. The book contains scientifically based chapters explaining the basic mechanisms of exercise-induced oxidative damage. Also covered are methodological approaches to assess the effectiveness of antioxidant treatment. Biomarkers are discussed as a method to estimate the bioefficacy of dietary/supplemental antioxidants in sports. This book is useful for sport nutrition scientists, physicians, exercise physiologists, product developers, sport practitioners, coaches, top athletes, and recreational athletes. In it, they will find objective information and practical guidance.




Magnesium in the Central Nervous System


Book Description

The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.




Recognition and Alleviation of Distress in Laboratory Animals


Book Description

Scientific advances in our understanding of animal physiology and behavior often require theories to be revised and standards of practice to be updated to improve laboratory animal welfare. This new book from the Institute for Laboratory Animal Research (ILAR) at the National Research Council, Recognition and Alleviation of Distress in Laboratory Animals, focuses on the stress and distress which is experienced by animals when used in laboratory research. This book aims to educate laboratory animal veterinarians; students, researchers, and investigators; animal care staff, as well as animal welfare officers on the current scientific and ethical issues associated with stress and distress in laboratory animals. It evaluates pertinent scientific literature to generate practical and pragmatic guidelines. Recognition and Alleviation of Distress in Laboratory Animals focuses specifically on the scientific understanding of the causes and the functions of stress and distress, the transformation of stress to distress, and the identification of principles for the recognition and alleviation of distress. This book discusses the role of humane endpoints in situations of distress and principles for the minimization of distress in laboratory animals. It also identifies areas in which further scientific investigation is needed to improve laboratory animal welfare in order to adhere to scientific and ethical principles that promote humane care and practice.




Adaptation Biology and Medicine


Book Description

Recognition of adaptive processes in biological systems as a discipline is still in its infancy. It is known that repeat exposure to low level stresses such as heat, cold, microgravity, hypoxia, exercise, etc. increases body-resistance to not only the particular stress but also to other conditions. Such a cross-protection can be utilized in a better patient care. This volume describes most current developments in the understanding of the molecular basis of adaptation as well as its application in biological systems including certain disease conditions in humans. The book is based on the presentations made by internationally known experts assembled in San Diego, USA for the 7th World Congress of the International Society for Adaptive Medicine and will be of great interest to experimental biologists as well as clinicians who deal with a wide variety of clinical conditions.
