Circadian rhythms are such an innate part of our lives that we rarely pause to speculate why they even exist. Some studies have suggested that the disruption of the circadian system may be causal for obesity and manifestations of Metabolic Syndrome (MetS). Shift-work, sleep-deprivation and bright-light-exposure at night are related to increased adiposity (obesity) and prevalence of MetS. It has been provided evidence of clock genes expression in human adipose tissue and demonstrated its association with different components of the MetS. Moreover, current studies are illustrating the particular role of different clock genes variants and their predicted haplotypes in MetS. The purpose of "Chronobiology and Obesity" is to describe the mechanisms implicated in the interaction between chonodisruption and metabolic-related illnesses, such as obesity and MetS, with different approaches.

Current molecular understanding of estrogen action has greatly profited from advances in molecular cell biology. These advances, and their implications for clinical use, were discussed by leading researchers from industry and academia during an international symposium held in Berlin, 1-3 March 2006 and are featured in this volume.

This unique compendium provides more detailed information on each drug than any other standard pharmacology title.

Clinical Urologic Endocrinology: Principles for Men's Health provides an organized, accessible reference on men's endocrinological health. Over 30 million men in the US alone suffer from erectile dysfunction and over 13 million men in the US suffer from hypogonadism (low testosterone). One out of seven couples also suffer from subfertility of which 50-60% have male factor involvement. More and more men are coming forward to seek treatment for such issues, which in the past were considered taboo and there is a strong need for a book which provides guidance for practitioners who support men in their reproductive and sexual concerns. This book covers in depth the key issues in male reproductive health in one easy-to-use resource. Clinical Urologic Endocrinology: Principles for Men's Health is a valuable reference for urologists, endocrinologists, internal medicine physicians, family medicine physicians, sex therapists, and allied health professionals providing care for men in the areas of sexual health, fertility, and men's endocrinological health.

Ghrelin, the endogenous ligand for the growth hormone secretagogue (GHS) receptor, is critical in the control of food intake and energy balance. The ghrelin receptors are now known to have important physiological properties as modulators of growth hormone release, appetite, glucose homeostasis, metabolism, immune function, neurotransmitter activity, cognitive function and neurodegeneration. Bringing all of this information together in the first comprehensive text on the topic, Ghrelin in Health and Disease provides a state-of-the-art synthesis of the latest work in this area for physicians and physician-scientists. This volume addresses the unique property of ghrelin as a modulator of function. Such a property provides potential utility for safe intervention in a wide variety of disease states. Indeed as we learn more about the basic physiology of ghrelin, the potential for treating new disease targets emerge requiring validation in the clinic. Each chapter in this volume is authored by a leading investigator in the field. The introductory chapter sets the background for the book and provides a superb overview of the relevance of ghrelin to physiology, describing how the discovery of ghrelin has prompted us to completely rethink traditional physiology. The authors conclude their chapters by critically addressing the future translational aspects of ghrelin biology and outlining what key basic research and clinical questions remain to be addressed. An invaluable resource, Ghrelin in Health and Disease distinguishes itself as the first comprehensive title covering all of the molecular and clinical issues relating to ghrelin and advancing our clinical understanding of obesity, growth, and reproductive pathogenesis.

Developed by renowned experts, this comprehensive and easy to read title offers a state-of-the-art description of the management of endocrine, diabetic, and metabolic emergencies and brings the field fully up to date, setting a high standard for diagnosis and treatment in each category. All chapters begin with a summary that presents, in concentrated form, what the physician needs to know to begin the evaluation and emergency treatment of the known endocrine emergencies. This is followed by an extended discussion of the pathophysiology that can be read after initial treatment has begun. Covering such areas as hypoglycemia, acute adrenal insufficiency, ovarian hyperstimulation syndrome, thyroid storm, and pituitary apoplexy, just to name several, Endocrine Emergencies: Recognition and Treatment is an invaluable, practical resource that will be of great interest to endocrinologists, internal medicine and emergency room physicians, fellows and residents.

The scientific advances in the physiology and pathophysiology of adipose tissue over the last two decades have been considerable. Today, the cellular and molecular mechanisms of adipogenesis are well known. In addition, adipose tissue is now recognized as a real endocrine organ that produces hormones such as the leptin acting to regulate food intake and energy balance in the central nervous system, a finding that has completely revolutionized the paradigm of energy homeostasis. Other adipokines have now been described and these molecules are taking on increasing importance in physiology and pathophysiology. Moreover, numerous works have shown that in obesity, but also in cases of lipodystophy, adipose tissue was the site of a local low-grade inflammation that involves immune cells such as macrophages and certain populations of lymphocytes. This new information is an important step in the pathophysiology of both obesity and related metabolic and cardiovascular complications. Finally, it is a unique and original work focusing on adipose tissue, covering biology and pathology by investigating aspects of molecular and cellular biology, general, metabolic, genetic and genomic biochemistry.

The obesity epidemic has generated immense interest in recent years due to the wide-ranging and significant adverse health and economic consequences that surround the problem. Much attention has been focused on behaviors that lead to obesity, in particular to over consumption of energy-dense food and to sedentary lifestyle. However, obesity is an extremely complex condition with poorly defined pathogenesis. Thanks to greatly enhanced research in the area, the discovery of pathways in the brain and peripheral organs that mediate energy homeostasis has provided a framework for understanding the biological basis of obesity. Metabolic Basis of Obesity adds an important new dimension to the growing literature on obesity by offering a comprehensive review of specifically how metabolic imbalance culminates in obesity. Developed by a team of expert authors, this important title discusses the principles of energy balance, genetics of body weight regulation, hormones and adipokines, and metabolic pathways in the brain, liver, muscle and fat, to name just several of the areas covered. The book also examines the connection between obesity and diabetes, cardiovascular disease and other complications. Current and future diagnostic and treatment strategies are also reviewed. Comprehensive and timely, Metabolic Basis of Obesity is an essential reference for understanding the burgeoning problem of obesity.

In 1925, J. B. Collip (1925) reported that extracts of parathyroid gland contained an activity that raised calcium levels in the blood of parathyroidectomized animals, and suggested that this was due to a hormone produced in the parathyroid gland. The story of parathyroid hormone discovery was indicative of ever-increasing sophistication in sample preparation and protein isolation techniques. This paper resolved earlier controversies over the function of the parathyroid glands and c- trol of blood calcium. The year 1961 was a banner year for parathyroid research, in which the peptides parathyroid hormone and calcitonin were purified, and in which it was suggested that calcitonin could lower blood calcium (Copp and Cameron 1961). In 1982 it was discovered that in neurons the primary RNA transcript for calcitonin could be alternatively-spliced to give calcitonin gene-reated peptide (CGRP), and shortly thereafter amylin (previously named islet amyloid polyp- tide, IAPP) was identified and shown to have homology to CGRP. Since then a and b CGRP have been delineated and adrenomedullin and intermedin discovered, and this family of homologous peptides has emerged. This family of peptide hormones has a diverse and constantly expanding range of important physiologic functions, including regulation of blood calcium, vascular tension, feeding behavior and pain recognition.

As the title suggests, and unlike other existing books on sleep medicine, Neuroendocrine Correlates of Sleep/Wakefulness will be devoted primarily to endocrine regulation of the behavioral state control. It will address a wide spectrum of sleep./wakefulness phenomena (both animals and humans), including pathogenesis, diagnosis, and management. From molecular biology to applied clinical therapy, sleep research has been transformed in the last few years from a research backwater to an important interdisciplinary field. Anyone who regularly reads the literature on sleep, biological rhythms, or neuroendocrinology is aware that one of the subspecialties within sleep medicine, the neuroendocrine correlates of sleep/wakefulness, has in particular experienced a growth rate that is even faster than that of the field as a whole. To a significant extent this has been due to the introduction of new research technologies. The widespread adoption of a range of new methods in sleep research has opened a window into activities at the cellular and molecular level, which previously had been tightly closed. Consequently these activities are being characterized with a degree of precision and sensitivity that is without precedent. This volume invites the reader to explore the new vistas that have been opened onto the neuroendocrine frontier of sleep medicine. The editors have selectively identified a number of key articles having a citation frequency, which is considerably above the norm or which otherwise have contributed importantly to defining the neuroendocrine perspective. This new volume on Neuroendocrine Correlates of Sleep/Wakefulness is an up-to-date resource of research summaries and reviews written by major contributors to the fields of sleep, biological rhythms and neuroendocrinology. Its coverage is broad and its basic and clinical science reviews are detailed. In this volume, an international team of experts discuss their latest ideas, concepts, methods, and interpretations with supporting examples. This volume is intended for advanced students and specialists in psychobiology, neuroscience, neuroendocrinology, and psychiatry but might also be interest to anyone concerned with understanding the Neuroendocrine correlates of sleep/wakefulness. The contributions are directed more towards providing an integrated view of the field from the perspective of the authors, rather than being a compendium of recent results. The intent is to provide a reference book for recent and future workers in this and related areas of medicine and biology. Each topic in this volume has received the attention of a panel of authors who have responded to our request to review and place into perspective the major issues, which will undoubtedly confront newcomers to the field. The topics dealt with in Neuroendocrine correlates of Sleep/wakefulness are both diverse and complex. The editors hope that this volume will provide an authoritative summary of important issues in the neuroendocrine correlates of sleep/wakefulness. We also hope that it will motivate new researchers to join the quest for solutions to the problems that have been identified by our contributing authors.

Hormone Receptors in Breast Cancer provides an up-to-date resource of the role of hormone receptors in breast cancer written in depth for both the basic molecular academic researcher and translational scientist. Advances in basic science of molecular endocrinology have undoubtedly been translated into clinical practice, and clinicians caring for this disease need to be knowledgeable about these developments. The molecular basis of hormone action has been elucidated, and the relative significance of the different estrogen and progesterone receptor isoforms has been explored. This explosion of information has lead to exciting new areas of gene specific targeting of the disease, and breast cancer prevention. Paradigm shifts in treatment options and sequencing have recently occurred in breast cancer management, necessitating close cooperation and communication between translational scientists and physicians. This book is focused on providing this communication.

The first report that rapid eye movements occur in sleep in humans was published in 1953. The research journey from this point to the realization that sleep consists of two entirely independent states of being (eventually labeled REM sleep and non-REM sleep) was convoluted, but by 1960 the fundamental duality of sleep was well established including the description of REM sleep in cats associated with "wide awake" EEG patterns and EMG suppression. The first report linking REM sleep to a pathology occurred in 1961 and a clear association of sleep onset REM periods, cataplexy, hypnagogic hallucinations and sleep paralysis was fully established by 1966. When a naive individual happens to observe a full-blown cataplexy attack, it is both dramatic and unnerving. Usually the observer assumes that the loss of muscle tone represents syncope or seizure. In order to educate health professionals and the general public, Christian Guilleminault and I made movies of full-blown cataplectic episodes (not an easy task). We showed these movies of cataplexy attacks to a number of professional audiences, and were eventually rewarded with the report of a similar abrupt loss of muscle tone in a dog. We were able to bring the dog to Stanford University and with this as the trigger, we were able to develop the Stanford Canine Narcolepsy Colony. Breeding studies revealed the genetic determinants of canine narcolepsy, an autosomal recessive gene we termed canarc1. Emmanuel Mignot took over the colony in 1986 and began sequencing DNA, finally isolating canarc1 in 1999.

Polycystic ovary syndrome (PCOS) is a classic female infertility condition affecting an estimated 6-10% of all women, many of whom are unaware of the problem. A disease that affects women from adolescence to menopause, PCOS is the single most common endrocrinologic abnormality affecting women. This book is an edited collection of writings that comprehensively covers the disease, from diagnosis and epidemiology of PCOS to clinical evaluation.

Creating clinical guidelines is a modern trend. Published studies pertaining to a given theme are collected, their credibility evaluated, and then treatment options in the form of evidence-based guidelines are offered. There are a number of guidelines for the treatment of thyroid tumors that have established positions in clinical practice in North America and in Western European countries. In Japan, however, where radioisotope facilities are of limited availability, treatment plans for differentiated thyroid cancer differ considerably from those of America and Europe, and the associated clinical guidelines need modification before they can be adopted. In addition, although thyroid tumor is a common disease in endocrine practice, its management can differ even among specialists. Thus, a Japanese clinical guideline for the treatment of thyroid tumor was desired by many clinicians. As a combination of evidence-based and consensus-based guidelines for the treatment of thyroid tumor, this book offers alternatives to conventional approaches in the West. Ultimately, the authors hope the guideline will lead to the best possible treatment for patients all over the world in the not-distant future.

Why sex matters Among human and nonhuman animals, the prevalence and intensity of infection typically is higher in males than females and may reflect differences in exposure as well as susceptibility to pathogens. Elevated immunity among females is a double-edged sword in which it is beneficial against infectious diseases but is detrimental in terms of increased development of autoimmune diseases. The present book critically reviews the evolutionary origin and the functional mechanisms responsible for sexual dimorphism in response to infection. It emphasizes the value of examining responses in both males and females to improve our understanding about host-pathogen interactions in both sexes. The contributors are experts in their specific disciplines which range from microbiology and immunology to genetics, pathology, and evolutionary biology. The book aims at bringing insight to the treatment and management of infectious diseases; it delineates areas where knowledge is lacking and highlights future avenues of research.

As a result of the rapidly growing rate of obesity worldwide, clinicians are struggling to provide the best strategies for treating obese patients with concomitant pulmonary conditions. Obesity does not simply change the epidemiology of pulmonary disease; obesity has a profound impact on the pathophysiology of common pulmonary diseases. Obesity affects the severity of asthma, response to treatment, and is likely a major modifier of the phenotype of asthma. Obesity also appears to affect response to pathogens, and as such has a major influence on response to pneumonia, and has a significant impact on outcomes pertaining to acute lung injury in the intensive care unit. Obesity and Lung Disease: A Guide to Management is the first text in the field to cover the full range of issues related to managing obese patients with pulmonary problems. All the relevant conditions, in the context of obesity, are covered, including airway inflammation, sleep apnea, asthma, pulmonary hypertension, obesity hypoventilation, as well as others. Written by an international group of experts, this important new volume is an invaluable resource for all clinicians and scientists concerned with the challenging problems surrounding obesity and lung diseases.

MRI Atlas of Pituitary Imaging focuses on magnetic resonance imaging (MRI), the imaging modality of choice for the evaluation of pituitary disorders, since it provides a detailed anatomy of the pituitary gland and surrounding structures, particularly the soft tissues. A basic understanding and interpretation of MRI is important for many clinicians outside of the field of radiology, especially endocrinologists who may receive limited formal training in such areas. This concise Atlas includes a brief review of the principles of magnetic resonance imaging and then reinforces these principles by utilizing a case-based approach to review various pituitary pathologies. The Atlas serves as a strong clinical teaching aid for endocrinologists, radiologists, and neurosurgeons in training. It also serves as a great reference for physicians who are currently in practice.

Molecular biology emerged from advances in biochemistry during the 1940s and 1950s, when the structure of the nucleic acids and proteins were elucidated. Beginning in the 1970s, with nucleic acid enzymology and the discovery of the restriction enzymes, the tools of molecular biology became widely available and applied in cell biology to study how genes are regulated. This new knowledge impacted endocrinology and reproductive biology since it was largely known that the secretion of the internal glands affected the phenotypes, and expression of genes. Modern reproductive biology encompasses every level of biological study from genomics to ecology, encompassing cell biology, biochemistry, endocrinology and general physiology. All of these disciplines require a basic knowledge, both as a tool and as an essential aid to a fundamental understanding of the principles of life in health and disease. Overall, molecular biology is central to scientific studies in all living matter, impacting disciplines such as medicine, related health sciences, veterinary, agriculture and environmental sciences. In this book, the basic biochemistry of nucleic acids and proteins are reviewed. Methodologies used to study signaling and gene regulation in the endocrine/reproductive system are also discussed. Topics include mechanisms of hormone action and several endocrine disorders affecting the reproductive system. Professionals in the medical, veterinary and animal sciences fields will find exciting and stimulating material enhancing the breadth and quality of their research.

Responding to a renewed interest in the growing problem of iodine deficiency worldwide, Drs. Charles Oxnard and Peter Obendorf, along with experienced translator and anatomist John Dennison, take a fresh look at the classic text, Der endemische Kretinismus, published in 1936 by Springer. Translated here for the first time into English, this landmark text will be a welcome resource for researchers confronting the problem of iodine deficiency. Oxnard and Obendorf point out that there is very little detailed knowledge or numerical data on cretinism available in the English-speaking world. In addition, highly-renowned Professor Basil S. Hetzel, recently-retired World Health Organization Chairman of the International Council for Control of Iodine Deficiency Disorders, published in 2009 with Dr Chen Zu-pei on the resurgence of iodine deficiency in China. Indeed, throughout the entire developing world there may be as many as two billion people at risk to iodine deficiency; perhaps three quarters of a billion have goiter, and ten million may be cretins. Even in developed countries, iodine deficiency is re-emerging (as in New South Wales in 19% of children) with the result of significantly reduced numbers of gifted children (though this is not cretinism per se). Certain to be of significant interest to a wide range of researchers, health providers and professionals, including government health administrators, this English translation of Endemic Cretinism is a major contribution to the literature.

Genomics in Endocrinology focuses on exciting new advances in endocrinology resulting from DNA microarray studies and includes a comprehensive introduction to the use of DNA microarrays in endocrinology. The text provides the basis for further understanding of the usefulness of microarray analyses in endocrinology research. Topics discussed include the methodology of DNA microarrays and general methods for the analysis of microarray data.

Since its ?rst description in 1942 in both serum and cerebrospinal ?uid, transthyretin (TTR) has had an eventful history, including changes in name from "prealbumin" to "thyroxine-binding prealbumin" to "transthyretin" as knowledge increased about its functions. TTR is synthesised in a wide range of tissues in humans and other eutherian mammals: the liver, choroid plexus (blood- cerebrospinal ?uid barrier), retinal pigment epithelium of the eye, pancreas, intestine and meninges. However, its sites of synthesis are more restricted in other vertebrates. This implies that the number of tissues synthesising TTR during vertebrate evolution has increased, and raises questions about the selection pressures governing TTR synthesis. TTR is most widely known as a distributor of thyroid hormones. In addition, TTR binds retinol-binding protein, which binds retinol. In this way, TTR is also involved with retinoid distribution. More recently, TTR has been demonstrated to bind a wide variety of endocrine disruptors including drugs, pollutants, industrial compounds, heavy metals, and some naturally occurring plant ?avonoids. These not only interfere with thyroid hormone delivery in the body, but also transport such endocrine disruptors into the brain, where they have the potential to accumulate.

The prevalence of hypertension is almost three times as high as that of diabetes mellitus type 2, with both conditions being major risk factors for stroke, ischemic heart disease, cardiac arrhythmias, and heart failure. The exact prevalence of hypertension related to hormonal derangements (endocrine hypertension) is not known but estimated to affect less than 15% of hypertensive patients. Recent scientific discoveries have increased the understanding of the pathophysiologic mechanisms of hypertension. In Endocrine Hypertension, a renowned panel of experts provides a comprehensive, state-of-the-art overview of this disorder, discussing when to assign an endocrine cause in one of many conditions that may present with hypertension. The first part of Endocrine Hypertension is dedicated to adrenal causes. The second part of the volume concerns potential nonadrenal causes of hypertension, such as growth hormone excess or deficiency, primary hyperparathyroidism, vitamin D deficiency, testosterone deficiency, insulin resistance, obesity-associated hypertension, and the role of central mineralocorticoid receptors and cardiovascular disease. An important contribution to the literature, Endocrine Hypertension is an indispensable reference not only for endocrinologists, diabetologists, and adrenal investigators, but also for translational scientists and clinicians from cardiology, internal medicine, pediatrics, family medicine, geriatrics, urology, and reproductive medicine / gynecology.
