Anabolic steroids have traditionally been controversial in the sporting arena. Today, research indicates a dramatic increase in the use of anabolic steroids and other performance-enhancing drugs outside of competitive sports. With evidence of widespread steroid abuse among the general population, health professionals are citing the emergence of an
Research on Steroids contains the proceedings of the Fourth Meeting of the International Study Group for Steroid Hormones. The papers explore the production, chemical characterization, and metabolism of steroid hormones and their interactions with proteins. Topics range from the action of estradiol in vitro to water-soluble metabolites of estrogens, transport of steroids by proteins, and immunological aspects of steroid hormones. The binding of steroids by tissue proteins is also discussed, along with the use of specific plasma proteins for the determination of steroids. This volume is compris...
This volume was planned to provide a comprehensive survey of the role of the anabolic-androgenic steroids in the vital economy exclusive of the androgenic (sexual) functions. It seemed appropriate to bring together all of this information in an organized fashion in one volume at this time not only to serve as a source of information but also to indicate and suggest areas that need further exploration. The anabolic action of the steroid hormones has gone through a period of great activity in both basic and clinical research. A complete understanding of the manifold anabolic effects still remains to be elucidated and the art of clinical application is only gradually becoming apparent. This volume should be useful not only to the experienced investigator in both basic and clinical research but also for the novice. Furthermore, it should serve as a source of information for the careful use of these steroids in certain metabolic diseases. These steroids have had wide clinical application with variable results. In many instances further careful exploration is suggested. Other instances have demonstrated varying degrees of usefulness.
Research on Steroids contains the proceedings of the Fourth Meeting of the International Study Group for Steroid Hormones. The papers explore the production, chemical characterization, and metabolism of steroid hormones and their interactions with proteins. Topics range from the action of estradiol in vitro to water-soluble metabolites of estrogens, transport of steroids by proteins, and immunological aspects of steroid hormones. The binding of steroids by tissue proteins is also discussed, along with the use of specific plasma proteins for the determination of steroids. This volume is comprised of 38 chapters and begins with an overview of the general aspects of steroid-protein interaction, followed by a discussion on quantitative studies of steroid binding proteins; aromatization of testosterone by human placenta enzymes; relationship between plasma binding and 5a-reduction of testosterone; cortisol-binding capacity of plasma transcortin in subjects treated with various anabolic steroids; and plasma testosterone binding capacity and estrogen excretion in normal and pathological pregnancies. Subsequent chapters deal with the interaction between estrogenic and carcinogenic substances in the rat mammary gland; influence of steroid production on serum albumin in Cushing's syndrome; and nuclear estradiol binding proteins in the uterus. This book will be of interest to biochemists, biologists, and physiologists.
This text presents research findings on the use and abuse of steroids in sports and exercise, and information on steroid use within professional sports and among Olympic athletes. In addition, information on drug use among international student athletes, adolescents and body builders is explored.
Drug abuse and addiction are common in clinical practice. Often they interfere with patient treatment or require an alternative approach. Drug Abuse and Addiction in Medical Illness: Causes, Consequences, and Treatment is a major contribution to the literature, a gold standard title offering a comprehensive range of topics for those who care for patients with addiction, conduct research in this area, or simply have an interest in the field. Offering state-of-the-art information for all those working with drug abusing or addicted patients, or for those interested in this topic from other research perspectives, the volume is a first of its kind book -- rich, comprehensive, yet focused, addressing the needs of the very active theoretical, basic, and clinical research in the field. Comprised of 46 chapters organized in four sections and developed by the leading international experts, Drug Abuse and Addiction in Medical Illness: Causes, Consequences, and Treatment covers virtually every core, as well as contemporary, topic on addiction, from the established theories to the most modern research and development in the field. Enhancing the educational value of the volume, every chapter includes an abstract and two boxes summarizing learning objectives and directions for future research. Drug Abuse and Addiction in Medical Illness: Causes, Consequences, and Treatment discusses the topic in a authoritative, systematic manner and is an indispensable reference for all clinicians and researchers interested in this rapidly changing field.
Anabolic steroids are synthetic forms of the hormone testosterone that can be taken orally, injected, or rubbed on the skin. Although a 2006 survey funded by the National Institute on Drug Abuse (NIDA) found that less than 3 percent of 12th graders had abused anabolic steroids, it also found that about 40 percent of 12th graders described anabolic steroids as "fairly easy" or "very easy" to get. The abuse of anabolic steroids can cause serious health effects and behavioral changes in teenagers. GAO was asked to examine federally funded efforts to address the abuse of anabolic steroids among teenagers and to review available research on this issue. This report describes (1) federally funded efforts that address teenage abuse of anabolic steroids, (2) available research on teenage abuse of anabolic steroids, and (3) gaps or areas in need of improvement that federal officials and other experts identify in research that addresses teenage anabolic steroid abuse. To do this work, GAO reviewed federal agency materials and published studies identified through a literature review and interviewed
The world is faced with an epidemic of metabolic diseases such as obesity and type 2 diabetes. This is due to changes in dietary habits and the decrease in physical activity. Exercise is usually part of the prescription, the first line of defense, to prevent or treat metabolic disorders. However, we are still learning how and why exercise provides metabolic benefits in human health. This open access volume focuses on the cellular and molecular pathways that link exercise, muscle biology, hormones and metabolism. This will include novel “myokines” that might act as new therapeutic agents in the future.
