The isolation of leptin in 1994 and its characterization as a factor influencing appetite, energy balance, and adiposity, immediately thrust the polypeptide into the rapidly growing body of literature centered on the physiology of obesity. The growing clinical awareness of obesity as a major health risk in developed societies dovetailed perfectly with any of a number of roles that leptin might play in this abenant physiological condition. Almost unnoticed amidst the excitement generated by early leptin publications was the suggestion that the "fat hormone" might also regulate a wide range of systems and events important to reproduction, including pubertal development, gonadal endocrinology, fettility, and pregnancy. Recognizing this potential, a relatively small cadre of researchers began to examine leptin specifically as a reproductive hormone, thus creating a new and fertile field of investigation. Interest in this area has since gained momentum and an increased number of participants have now made significant contributions to our understanding of many leptin-related mechanisms that are relevant to reproductive biology. Leptin and Reproduction is the first major volume to specifically address leptin as a reproductive hormone and closely examines the advances made in the short time since this field of interest developed. Preeminent researchers ti'om many of the subdisciplines working within this area present a welcomed compendium of the wealth of related literature and voice novel interpretations of cun'ent advances.

It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.

It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.

Functional Metabolism of Cells is the first comprehensive survey of metabolism, offering an in-depth examination of metabolism and regulation of carbohydrates, lipids, and amino acids. It provides a basic background on metabolic regulation and adaptation as well as the chemical logic of metabolism, and covers the interrelationship of metabolism to life processes of the whole organism. The book lays out a structured approach to the metabolic basis of disease, including discussion of the normal pathways of metabolism, altered pathways leading to disease, and use of molecular genetics in diagnosis and treatment of disease. It also takes a unique comparative approach in which human metabolism is a reference for metabolism in microorganisms and plant design, and presents novel coverage of development and aging, and human health and animal adaptation. The final chapter reviews the past and future promise of new genetic approaches to treatment and bioinformatics. This, the most exhaustive treatment of metabolism currently available, is a useful text for advanced undergraduates and graduates in biochemistry, cell/molecular biology, and biomedicine, as well as biochemistry instructors and investigators in related fields.

This unique book – the first ever on bariatric endocrinology – is a comprehensive endocrine and metabolism approach to the diseases that result from excess fat mass accumulation and adipose tissue dysfunction. It takes an approach that places adipose tissue at the center of the clinical approach to patients, as opposed to the complications of adipose tissue accumulation and dysfunction, which has been the dominant approach to date. Initial chapters include discussion of adipose tissue physiology and pathophysiology (adiposopathy), hormonal, central nervous system, and gut microbiome regulation of energy balance and stores, and primary and secondary causes of adipose tissue weight gain. Subsequent chapters cover the evaluation and treatment of dyslipidemia, insulin resistance and hyperglycemic states, hypertension, neoplasia, and gonadal function in men and women. Management strategies, such as nutrition, physical activity, pharmacotherapy, and bariatric procedures, round out the presentation. Each chapter is bookended by bullet-pointed clinical pearls at the beginning and a full reading list at the end. Written and edited by experts in the field of endocrinology and obesity management, Bariatric Endocrinology redefines practice to focus not just on weight loss as measured in pounds lost, but on adipose tissue mass and pathology, decreasing fat mass for adiposity-related diseases and returning adipose tissue to normal function.
