This book presents an authoritative review of the research regarding the influences of anabolic-androgenic steroids on metabolism. The book provides a concise description of the biochemistry of these steroids using simple terms and includes methods of separation and their clinical applications. The first section of the book examines the general structure, nomenclature, and classification of anabolic-androgenic steroids. Subsequent chapters explore concepts basic to understanding the pathways of their metabolism in both target and non-target tissues, including the interactions of steroids with receptors and the effects of steroids on the cellular metabolism of skeletal muscle. The changes and molecular base of modifications in metabolism during exercise involving anabolic-androgenic steroids are also described. Finally, a comprehensive review of methods for scanning and identifying anabolic-androgenic steroids in biological fluids is presented, as well as a discussion regarding the applicability and limitations of these techniques. The book provides valuable reference information for all scientists and clinicians engaged in sports medicine, exercise biochemistry, and endocrinology.

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.

This volume is intended for clinicians, researchers, residents, and students. The range is wide and the depth considerable for all the topics covered in the treatment of this timely and relevant subject. This book may serve equally well as a general introduction and a scholarly reference. Ultimately, it is designed to serve those patients suffering from abuse of and addiction to drugs and alcohol. The content and organization of the book flow from general concepts of abuse and addiction to specific details of the pharmacology of alcohol and drugs. Special chapters on topics not found in most other books, such as pharmacology of drug-drug interactions, abstinence, and prevention, are included. This book is written especially for the clinician interested in the pharma cology of alcohol and drugs of abuse and addiction. The pharmacology is integrated into a conceptual approach to diagnosis and treatment of alcohol and drug abuse and addiction. The form and style are didactic, critical as well as straightforward in presentation. Literature references from recent clinical research and basic research provide the foundation for the chapters throughout the book. Be cause the book is written by a clinician-researcher, the information is readily adaptable to clinical problems and research ideas. I would like to express my deep appreciation to Susan Newsom and Darlene Tucci for their invaluable technical assistance. Norman S.

Doping, Performance-Enhancing Drugs, and Hormones in Sport: Mechanisms of Action and Methods of Detection examines the biochemistry and bioanalytical aspects of performance-enhancing drugs (PEDs) and other questionable procedures used by athletes to enhance performance. The book informs the specialist of emerging knowledge and techniques and allows the non-specialist to grasp the underlying science and current practice of the discipline. With clear and compelling language appropriate for a broad spectrum of readers, this book provides background on prevalence, types of agents, their actual or supposed benefits, and their negative effects on health. The technical aspects of detection are discussed, followed by a discussion of why detection is a problematic and still-evolving science. To facilitate comprehension, each chapter is organized in a uniform way with six sections: (1) standard medical uses, (2) why the drugs are used by athletes, (3) biological mechanism of action, (4) what research says about efficacy in improving performance, (5) major health side effects from use and abuse in sport, and 6) concluding key points. - Presents the scientific concepts of how performance enhancers work, how they are used, and how they are detected and masked from detection - Features language that is neither simplistic to scientists nor too sophisticated for a large, diverse global audience - Provides a short "close-up in each chapter to illustrate key topics that engage, entertain, and create a novel synthesis of thought

This book covers a selected number of hot topics in endocrine and hormone-related pathologies, discussed by eminent scientists and clinicians coming from different countries of the world. It deals with advanced recent trends in the field, including neuroendocrine and pituitary tumors, thyroid dysfunctions, diabetes and a series of endocrine-related diseases, such as those related to the anabolic effects of testosterone, obesity, cancer, the liver complications of diabetes and the pediatric nonalcoholic fatty liver disease. The readers should be able to have a basic, as well as critic and advanced, overview of these selected hot pathologies of the endocrine system.

This book provides a comprehensive overview of endocrinology of the male reproductive system, explaining how it works and how, sometimes, it fails to work. World-class specialists present state of the art knowledge on all aspects, including anatomy, physiology, molecular biology, genetics, pathophysiology, clinical manifestations of testicular diseases, endocrine aspects of andrological and sexual diseases, and therapy. Extensive consideration is given to sexual development, testicular function, the clinical approach to disorders of male reproduction, male hypogonadism, sexual dysfunction, and male infertility. In addition, sociodemographic, psychological, and ethical aspects of male reproductive disorders are discussed. The book is intended as a major reference for endocrinologists, andrologists, and sexologists, as well as basic and clinical scientists. It is published as part of the SpringerReference program, which delivers access to living editions constantly updated through a dynamic peer-review publishing process.
