Neuroendocrine Perspectives, Volume 7, is part of an international book series designed to keep clinicians and researchers appraised of important trends and new data in basic and clinical neuroendocrinology. It focuses on four very rapidly evolving major topics: - the role of dopaminergic regulation of the intermediate pituitary lobe in elucidating intracellular signal transaction pathways and other regulatory mechanisms involved in transsynaptic regulation of peptide biosynthesis, post-translational processing, and hormone secretion; - the physiological and clinical implications of corticotropin releasing factor for such areas as diagnosing Cushing's syndrome, defining the hypothalamic and pituitary origins of secondary adrenal insufficiency, and distinguishing Cushing's syndrome from psychiatric states associated with hypercortisolism; - the large number of neurotrophic factors that affect CNS neurons and of neurite promoting factors that modulate neuronal performance, with emphasis on their mechanisms of action and their possible therapeutic applications to peripheral neuropathies and central diseases; - and the many factors that regulate changes in female reproductive cycles during middle age, with careful distinction between neuroendocrine and ovarian components and special attention to the possible cause-and-effect relationship within the cascade of events resulting in acyclicity and infertility.

This book brings together some of the results and ideas produced by a large number of people-colleagues and students with whom I am privileged to work in the laboratory at Rockefeller University. In terms of my personal history I see it as a confluence of creative forces persons from whom I have learned. I was instructed in neuroanatomy by Walle J. H. Nauta at M. I. T., and later in a course at Harvard Medical School under the direction of Richard Sidman. At Harvard Medical School, where M. I. T. graduate students were allowed to cross register, the superb neurophysiology course was under the guiding spirit of Stephen Kuffler. Later, I benefited greatly from participating in his summer course in electrophysiological techniques at Woods Hole. Eric Kandel and his colleagues have provided us with the most exciting contemporary approach to the conceptualization and study of cellular mechanisms for behavior. Here at Rockefeller, Carl Pfaffmann and Neal Miller have been leaders in every sense of the word. Not only did they provide me with opportunities to grow to scientific maturity; they also set an example of clear thinking about mechanisms for mammalian behavior patterns. I wrote this book to show how the systematic use of increasingly detailed electrophysiological, neuroanatomical, and neuroendocrine tech niques can explain the mechanism for a mammalian behavioral response. The behavior in question happens to be sensitive to steroid hormones and plays a central role in reproduction."

Every year there are new and exciting developments in assisted human reproduction, but how much do we really know about the underlying causes of infertility? This volume explores recent progress in the understanding of the genetics of spermatogenesis and male infertility. Topics include fundamental advances and current problems in the development and function of the testis, an outline of clinical findings in male infertility and an overview of the role of the Y chromosome in male fertility. Comprehensive critiques of posttranscriptional control during spermatogenesis, mammalian meiotic sterility, and comparative genetics of human spermatogenesis from the perspective of yeast, Drosophila and mice provide a global overview of the field.

Leading workers in the field of human reproduction provide both basic knowledge and useful practical information in this book about the most critical phase in the development of a new human being: the first twelve weeks of life. The period from fertilization and implantation to the end of the first trimester is still insufficiently understood and marks a new frontier. The knowledge necessary for applying our present diagnostic capabilities and for venturing into the problematic areas of fertilization technology and embryonic treatment is made easily available in this comprehensive textbook. The book is divided into two parts. The first presents basic information about physiology, anatomy, in vivo investigations, biochemistry and legal aspects. The second part focuses on pregnancy development, monitoring and the clinical diagnosis and management of disorders in the early stages of life. A full section is devoted to assisted conception and the newest possibilities in fertilizationtechnologies, whereby the ethical aspects are also discussed.

In recent years, a series of excellent textbooks have been published dealing with pathology of the thyroid gland. The present volume of CURRENT TOPICS IN PATHOLOGY provides further information for both pathologists and clinicians interested in the thyroid gland. The contributions deal with surgical pathology of the thyroid as well as with basic aspects of thyroid metabolism, hormone transport, and growth factors in thyroid cells. The topics covered in this book should mainly be considered as adjuncts to common textbooks on thyroid pathology. The contributions should help pathologists in their routine diagnosis and should stimulate further thyroid research.

The fact that certain adrenal steroid hormones are immunosuppressive and anti-inflammatory has been known for many years, and is routinely exploited by physicians. These effects are attributable to glucocorticoid steroids such as cortisol. Pharmacological doses of glucocorticoids inhibit most or all T cell types. However we now know that the effect of exposure to raised physiological levels is mainly to drive developing lymphocyte responses towards a Th2 cytokine profile (interleukin-4 secreting) while suppressing the development ofThi (gamma interferon- secreting) lymphocytes. Only recently have two further regulatory mechanisms become appar- ent. First, these effects of cortisol are balanced by pro-inflammatory and ThI-enhancing effects of another adrenal steroid, dehydroepiandro- sterone sulfate (DHEAS). Second, the activity of cortisol is directly modulated by enzymes in the target organs and lymphoid tissues that convert it into inactive cortisone. This new information leads to the possibility that immunoregulatory steroids could be used by physicians in novel ways. We can envisage steroid combinations that exploit the anti-inflammatory effects of corti- sol, while the Thi-suppressing and Th2-promoting properties of these hormones are opposed by derivatives of DHEAS. Such therapies are already proving effective in animal models of infection, and could revol- utionize treatment of Th2-mediated diseases such as asthma, where the anti-inflammatory effects of cortisol are desirable but the effects on T lymphocyte differentiation are not.

Bilateral Communication Between the Endocrine and Immune Systems, "Volume 7" in the Springer-Verlag "Endocrinology and " "Metabolism" Series, offers the most current information and recent advances in the area of communication and regulation between the Immune and Endocrine Systems. Immune-Endocrine Interactions are reported to play pivotal roles in both activation and down-regulation of immune responses and this volume provides the most up-to-date research and findings on the immune-endocrine relationship. The contributing authors are internationally recognized experts in this area and have written chapters on such diverse topics as Interactions between the Pituitary and Immune Systems, Effects of Estrogens and Androgens on Immune Response, The Role of Sex Steroids in Immune System Regulation, and Neuroendocrine and Thymus Interactions During Development and Aging. This volume is a must for all endocrinologists and endocrinology residents.

A panel of leading experts integrate the latest findings from basic and clinical science to create a comprehensive treatment of the processes by which the brain acts as an endocrine organ, not only to control hormonal functions, but also to maintain homeostasis and regulate behavior. The authors-recognized both as leaders in their fields and as skilled teachers-provide systematic coverage of the analytical, anatomical, functional, clinical, and pathological aspects of neuroendocrinology. Topics range from the interactions between the nervous and endocrine systems to the regulation of reproduction, development, metabolism, fluid balance, and biological rhythms. Neuroendocrinology in Physiology and Medicine offers an unprecedented marriage of clinical and basic knowledge that has been missing from classical neuroscience, endocrinology, and physiology texts. It will teach today's medical students and serve researchers as a valuable reference to this rapidly growing field.

In the past five years, so much additional progress has been made in ourunderstanding of both the basic and c1inical aspects of a wide variety of thyroid disorders that a second edition of Diseases of the Thyroid was considered a necessary addition to the Contem porary Endocrinology series. Fresh perspectives also seemed warranted, so we recruited new authors for many of the chapters and believe that this edition will provide the reader with further insights into the pathophysiology and c1inical presentation and treatment of thyroid disease. It inc1udes topics ranging from neonatal thyroid screening, thyroid dysfunction during infancy and childhood, peripartum thyroid disorders, thyroid disease in the elderly, and the c1inical relevance of the sodiurnliodide symporter (NIS) to the pathogenesis and treatment of nodular goiter, thyroid cancer, thyrotoxicosis, and hypothyroidism. The worldwide problem of iodine deficiency and its eradication is also discussed, along with environmental goitrogens and iodine-induced thyroid disease. I am indebted to all the contributors for their cooperation and expertise in providing their chapters in an extremely timely fashion, to Mr. Thomas Moore and Mr. Craig Adams from Humana Press for their expert assistance, and to Ms. Christine Archung for providing superb administrative assistance.

During the past five to ten years, a variety of tools has been developed in the disciplines of both gene engineering, and molecular and structural biology. Some of these advances have permitted scientists not only to identify and characterize genes, but also to target these genes by disruption, thus eliminating their function in living animals, and to det- mine the biological responses to altered gene products. This has particular significance in endocrine systems, in which feedback mechanisms between the hypothalamus, pi- itary, and end organs are critical in normal physiology. Interpretation of the physiological significance, or the site of action of specific molecules in this context, has been difficult prior to transgenic technology. Major advances have occurred specifically in the areas of growth and development, and of reproduction. Coupled with analysis of naturally occurring mutations in humans, the use of transgenic animals and in vitro systems has recently allowed endocrinologists to understand the importance of specific thyroid hormone receptor isoforms in vivo, the molecular basis for generalized resistance to thyroid hormones via mutations in the nuclear receptor, and mechanisms for suppressing gene transcription. Previously designated "orphan rec- tors," such as steroidogenic factor-1, were demonstrated to have critical roles in dev- opment and reproduction. Other nuclear receptors-including those for thyroid hormone, estrogens, androgens, and progesterone-were shown to bind to coactivator and co- pressor proteins that modified their transcriptional activity, and contributed to the ce- specific effects of the hormones.

Distinguished clinician-scientists describe in concise studies their most difficult cases and reveal what they did, how they did it, and why. The cases cover a wide range of endocrine problems. Each case study reviews how the patient was managed, details the reasons why various tests and treatments-many only recently available-were carried out, and provides references to ensure that those novel methodologies can be easily translated into the endocrine specialist's daily practice. The authors provide practical solutions for these difficult-to-manage cases, and successfully apply knowledge fresh from the laboratory to decisions about patient management. Practical and stimulating, Challenging Cases in Endocrinology demonstrates for every clinical endocrinologist precisely how specialists approach their most challenging cases and how these approaches can be effectively applied in the daily practice of endocrinology.

The explosive growth in the field of molecular biology over the last two decades has started to make a great impact on clinical medicine. Genes have been cloned for diseases that were poorly understood only a decade ago. Additionally, investigators are increasingly aware that there are strong genetic components to complex disorders, such as osteoporosis, that are not classically thought of as genetic disorders. New insights into the pathogenesis of metabolic bone diseases have been obtained from investigations into the molecular biology of these diseases and new therapies will become available based on these new insights. In The Genefies of Osteoporosis and Metabolie Bane Disease, I have assembled an internationally renowned group of experts to write the various chapters. Each of the authors is an expert in his/her field who is currently performing research on the content of their chapter and have made important contributions to the understanding of the clinical fea tures and pathophysiology of metabolic bone disease and genetics. The first part of The Genefies of Osteoporosis and Metabolie Bane Disease addresses issues related to genetic contributions to the development of osteoporosis and the many factors that must be considered when searching for genesthat predispose to osteoporosis. The second sec tion addresses recent advances in the clinical and molecular biological aspects of inherited metabolic bone disorders. The last section reviews the latest techniques for finding genes that predispose to metabolic bone diseases.

Authoritative researchers and clinicians review our latest understanding of andrology in both basic science and clinical medicine. Topics range from explaining the biology of androgens-from several different perspectives-to illuminating their role in the development and modulation of physiologic systems. Authors demonstrate in a number of cases that testosterone can be a useful adjunct to the treatment of a variety of disease states. Other chapters consider important topics such as androgens use in athletes, the potential of androgens to improve physical function and quality of life in older men, and androgens as potential male contraceptives.

It has been over 40 years since the original report by Salmon and Daughaday demon strating that the ability of GH to stimulate sulfation of cartilage was mediated by a "sulfation factor. " In the ensuing decades, it has become apparent that this "sulfation factor activity" encompasses a complex system ofligands (IGFs), receptors, and carrier proteins that are, in tum, responsible for a wide array of cellular actions. The IGF system has been demonstrated to be critically involved in both intrauterine and postnatal growth, and to have important implications in cancer biology as well, owing to the ability of the IGFs to function in endocrine, paracrine, and autocrine modes and given the wide distri bution of IGFs in virtually every organ system. The contributions to The /GF System reflect the wide span of interest in the IGF system and its implications for normal and abnormal growth and metabolism. The chapters have been divided into four broad sections: I. Molecular biology of the IGF system; II. Bio logical actions of the IGFs; III. IGF physiology; and IV. Clinical aspects of the IGFs. We have made every effort to highlight the major contemporary themes in IGF biology, but as is inevitable in such a fast-moving field, perspectives will continue to change as new information is accumulated."

Gerald Reaven, the discoverer of Syndrome X, and a panel of world-class investigators thoughtfully summarize our current understanding of how insulin resistance and its compensating hyperinsulinemia play a major role in the pathogenesis and clinical course of high blood pressure and cardiovascular disease-the so-called diseases of Western civilization. These distinguished authorities detail, for the first time, the pathophysiological consequences and the clinical syndromes, excluding Type 2 diabetes, related to insulin resistance. They also examine the genetic and lifestyle factors that contribute to the wide differences in insulin action that exist in the population at large. Timely and authoritative, Insulin Resistance: The Metabolic Syndrome X illuminates the full importance of insulin resistance as a major cause of hypertension, heart disease, and polycystic ovary syndrome.

Don P. Wolf and Mary Zelinski-Wooten provide a comprehensive review of the procedures and techniques used in assisted reproduction, as well as in nuclear transfer for both the treatment of human infertility and the propagation of animals. Combining the details of clinical application with the physiological facts of reproduction, the authors treat subjects such as the in vitro maturation of oocytes, embryo culture, intracytoplasmic sperm injection, and the process of nuclear transfer. Cutting-edge and wide-ranging, Assisted Fertilization and Nuclear Transfer in Mammals offers clinical ARTs practitioners, research scientists, those responsible for animal care, and students not only an informative historical perspective on the development of ARTs, but also updates on several of the more dynamic clinical areas, and a highly practical understanding of their applications.

Leading researchers and experienced clinicians join forces not only to illuminate today's understanding of the endocrinology of menopause, but also to provide a sound basis for its successful management. These seasoned experts review in detail the cardiovascular, bone, brain, and genitourinary changes that accompany menopause and spell out the risks, benefits, and alternatives of conventional hormone replacement therapy. Selective estrogen receptor modulators (SERMs), androgen replacement, calcium supplementation, and the role of phytoestrogens are also fully reviewed. Menopause: Endocrinology and Management offers practicing physicians a comprehensive understanding of the menopause process, as well as an evidence-based approach to optimizing treatment strategies for the challenging medical problems accompanying this important period in women's lives.

Recent advances in non-invasive sampling techniques have led to an increase in the study of hormones and behaviour. Behaviour is complex but can be explained to a large degree by interactions between various psychological and physiological components, such as the interplay between hormonal and psychological systems. This new textbook from Nick Neave offers a detailed introduction to the fascinating science of behavioural endocrinology from a psychological perspective, examining the relationships between hormones and behaviour in both humans and animals. Neave explains the endocrine system and the ways in which hormones can influence brain structure and function, and presents a series of examples to demonstrate how hormones can influence specific behaviours, including sexual determination and differentiation, neurological differentiation, parental behaviours, aggressive behaviours and cognition. This introductory textbook will appeal to second and third year social science undergraduate students in psychology and biomedicine.

Biomedical devices that contact with blood or tissue represent a wide range of products. Depending on their potential harm to a body, medical devices are categorized according to the degree, so their safety can be assured. All biomaterials are by definition designed to contact with a body for a certain period of time. The nature of the body contact, as well as the duration a material contacts with the body may initiate unwanted biological In comparison with invasive devices Oike catheters and medical responses. implants contact directly with tissue or with the circulating blood) non invasive devices (like wound-dressings and contact lenses contact with the skin, the sclera, and the mucosa or with open wounds) have a lesser risk of hurting a patient. When blood contacts with a foreign material, plasma proteins become absorpted to the surface within a few seconds. The reactions that follow, the so-called intrinsic pathway lead to the formation of fibrin and activation of platelets and white blood cells, result in blood clot formation."
