This volume is a collection of the most significant contributions to the 4th International Symposium on MULTIPLE RISK FACTORS IN CARDIOVASCULAR DISEASE: STRATEGIES OF PREVENTION OF CORONARY HEART DISEASE, CARDIAC F AlLURE, AND STROKE held in Washington, D. C. in April 1997. The meeting focused on the risk factors for cardiovascular disease and their interactions. The need for this symposium is based on the epidemiological, clinical, and biological evidence that individuals from industrialized countries often possess two or more risk factors which synergistically increase the global risk profile. This has become more evident in recent years with the increase in life expectancy of populations in the industrialized countries. The evidence that a combination of risk factors confers a very high risk of developing cardiovascular diseases, is of pivotal interest in the process of detection of patients who will benefit the most from pharmacological treatment. Many recent epidemiological data identifying the intrinsic and environmental factors contributing to the development of atherosclerosis are discussed. These results, in parallel with basic and clinical research, underline atherosclerosis as a complex and multifactorial process involving the influences of lipids, including lipoprotein subfractions, blood pressure rheologic forces, carbohydrate tolerance, and thrombogenic factors, including fibrinogen, tissue factor, PAl-I, and homocysteine. Furthennore, the risk associated with anyone of these risk factors varies widely depending on the level of the associated atherogenic risk factors. Hyper cholesterolemia and hypertriglyceridemia, for instance, are more common than would be expected by chance among hypertensive patients.

Diabetes and cardiovascular disease together account for the largest portion of health care spending compared to all other diseases in Western society. This work seeks to provide an understanding of the causes of diabetes and its cardiovascular complications. As this understanding becomes more widely appreciated, it will serve as a foundation for evidence-based care and wider acceptance of sound science. The International Conference on Diabetes and Cardiovascular Disease, held in Winnipeg, in June 1999, was organized to bring together a multi-disciplinary group of researchers dedicated to further knowledge amongst researchers, care givers, and the managers of the health system. The invited speakers submitted their works for publication, which serves as the basis for this book. Major themes include: epidemiology of diabetes mellitus, metabolic risk factors in diabetes and cardiovascular disease, hypertension in diabetes mellitus, cardiac function in diabetes, glycemic control and improved cardiovascular function, diabetes management, and endothelial function in diabetes.

Despite the advent of insulin for clinical use in 1922, our ability to control hypergly cemia and prevent the long term sequelae ofthe disease remains limited. Thus normalization of the milieu interieur with physiologic responses of insulin and metabolites remains an elusive but critically important goal. The developing endocrine pancreas provides a model system that speaks to many challenges of the transplantation biologist. Thus the attempt to of vascularization, growth and development, immunologic toler recapitulate the ontogeny ance, and glucose responsive insulin secretory capacity of fetal islet tissue provides a tantalizing possibility to replace insulin secreting tissue in persons with diabetes. Studies of this tissue are also important because of the implications such investigations have for genetic and molecular biological approaches to restoring insulin secretion as well as for providing clues to enhancing the growth and repair of islets that have been the target of autoimmune disease. Investigators in the area offetal islet transplantation comprise a small group scattered throughout the world scientific community. Therefore it seemed important to provide a forum where these scientists could gather, share ideas, and achieve consensus such that progress in this rapidly evolving area could be facilitated. The conference would have remained a dream if the support of the Okla Basil Meade, Jr. family had not made it manifest."

Aaron I. Vinik, M.D., Ph.D. I IEastem Virginia Medical School The Diabetes Institutes Norfolk, Virginia 23510 This symposium, held in June 1991, was a gathering of international scientists to exchange their views on current concepts of cell growth and differentiation. Each scientist was asked to present a topic of their research related to cell growth and regeneration and to participate in a round table conference elaborating on current knowledge and sharing their experiences. By furthering this promising area of endeavor, a means of understanding ontogeny of cell development and of providing insights into tumor biology would prevail. Of prime importance was the anticipation that new information from a better understanding of the normal evolution of the pancreatic islet would generate alternative approaches to curing diabetes. This forward serves as a short introduction to the concept of pancreatic islet regeneration and the models currently in use to study the process. DEVELOPMENTAL ORIGIN OF ISLETS DURING EMRYOGENESIS The developing pancreas appears as a protrusion from the dorsal surface of the l embryonic gut. The different islet cell types appear sequentially during development in vivo. It therefore seems reasonable to propose that coordinated growth is dependent upon specificity of growth factors.

Diabetes mellitus is rapidly increasing in prevalence throughout both developed and developing countries. The social and economic burden of this disease is estimated to cost 14 billion dollars worldwide. In the USA alone, 15 million individuals are diabetic, nearly half of them unaware of their condition. Complications of diabetes mellitus are the leading causes for blindness, limb amputation and chronic renal failure and kidney transplantation in industrialized countries. Further, diabetes mellitus per se and the metabolic derangement associated with diabetes are important risk factors for cardiovascular disease. Diabetes, as defined by an elevated fasting blood glucose level is presently subdivided in etiologically distinct groups. The most prevalent being type 2 (adult onset) diabetes characterized by insulin resistance and failure of the ~-cell to supply insulin in amounts sufficient to meet the body's needs. Type 1 (juvenile) diabetes, most commonly with an onset during childhood and adolescence, is caused by an auto-immune destruction of the pancreatic ~-cells. The causations of both type 1 and type 2 diabetes involve a combination of complex genetic traits and environmental influences. A third category are the mature onset diabetes of the young (MODY). This comparatively small group of patients (-10% of diabetes) presents relative early in life "30 years of age) compared to the more common late onset type 2 diabetes.

This book will enlighten on some of the recent progress in diabetic care and therapy. Diabetes mellitus is a group of metabolic diseases in which a person has high blood sugar, either because the body does not produce enough insulin, or because of the inability of cells to respond to the insulin that is produced. According to the recent report of World Health Organization, 346 million people worldwide are suffering from diabetes, and in 2004, approximately 3.4 million people died as a result of high blood sugar. This book explores applying both classical and modern approaches to the management of diabetes by focusing on a holistic approach. Great attention has been focused on global trends in diabetes, epidemiology of diabetes, inhibitors in diabetes and diabetes therapy, vitamins and diabetes, and the role of dietary fats in diabetes in this book. Topics include: * diabetic foot ulcers and therapeutic footwear * Withania coagulans. Dunal as an antidiabetic herb * the pharmacological interventions for diabetic cardiomyopathy * the use of saliva as a noninvasive tool to monitor glycemic control in diabetic patients * a cutting-edge biomedical device for continuous in vivo glucose monitoring * the temporal effect of repeated stress in the pathophysiology of T2DM * nanosensor technology for glucose detection The editors and authors emphasize a holistic approach toward the diagnosis, treatment, and management of diabetes by joining hands with experts from various disciplines Medical students and doctors of modern medicine, Ayurveda, homeopathy, etc., medical reserachers, researchers in the area of diabetes, pharma professionals.

In September, 1977, at a conference organized by Dr. Kenneth McKerns in Northeast Harbor, Maine, USA, I was asked by the Editorial Committee of the Biochemical Endocrinology series to investigate the possibility of organizing the next meeting in France. I proposed a subject which is in the area of my research interest, and this subject was accepted. On arriving back in France, I first looked for an appropriate place for the meeting, and the Chateau de Seillac was chosen in accordance with many objective criteria. We know that all who attended the meeting held in Seillac enjoyed this quiet and charming place in the Loire Valley. The next step was to choose some experts in the field who would contribute to the monograph and present their papers at a conference for the purpose of generating discussions. The action of the local committee, composed of Dr. A. Tixier-Vidal, Dr. Claude Kordon, and me, was crucial in this respect. The local committee proposed the program for the meeting and a list of the majority of contributors to be invited. I wish to thank Dr. Tixier-Vidal and Dr. Kordon for their invaluable assistance.

The ciliopathies are a group of rare diseases that often affect multiple systems within the body, and are caused by defects in the function or structure of cilia. When cilia go wrong, there are profound consequences; these are discussed in detail for the first time in Ciliopathies: a reference for clinicians. The book provides a clinical overview and reference to this newly emergent group of disorders ranging from Alstroem syndrome to putative ciliopathic disorders. Each chapter provides an in-depth discussion on a specific disorder, including the latest scientific research together with a description of its features, and practical guidelines on diagnosis. The authors also examine the evidence for dysfunction of cilia in cancer and more common disorders. Ciliopathies: a reference for clinicians will appeal to those involved in the care of patients with ciliopathies, including specialists in the fields of nephrology, diabetes, cardiology, and ophthalmology, and non-clinical researchers interested in cilia biology.

In September of 1977 scientists from many countries met at the Asticou Inn in Maine to present and discuss papers written especially for this monograph. The presentations were informal and directed to the special interests of the audience in order to generate discussions. The authors, many of whom are pioneers and leaders in their field, then had the oppor tunity to revise their contributions, which were brought together with the edited discussions to form this volume. The basic research studies presented here are important because of the essential role of gonadotropins in regulating the ovary and testis. This monograph will therefore be of interest to those concerned with fertility regulation, population control, possible new methods for contraception, and to those concerned with reproduction in domestic animals. Re searchers in other fields may find this monograph useful, as it has been de termined that gonadotropins are secreted by many tumors and are im plicated in many cancers. Human choriogonadotropin also seems to be found in most, if not all, cells of the human body. The significance of this, however, is unknown."

Calcium-Sensing Receptor provides an overview of various aspects of the calcium receptor's biochemistry, physiology and pathophysiology that is suitable both for those who have been working in the field of Ca2+0-sensing as well as those who are new to this discipline. Calcium-Sensing Receptor is the nineteenth volume published in the Endocrine Updates book series under the Series Editorship of Shlomo Melmed, MD.

An enormous amount of research effort has been directed toward elucidating the mechanism by which substances are extruded from cells; and reviews have been written and symposia held in order to systematize the plethora of evidence made available. However, the approaches employed to study the secretory process have been so diverse that it is difficult, if not impossible, for one individual or even a group of individuals to keep abreast of all aspects of the field and to analyze them critically. Thus I undertook the writing of this volume with a great deal of trepidation. In searching for some starting point, I naturally considered as my primary focus the role of calcium in the secretory process, which has occupied my research interests for the past 13 years. But since so much experimentation has been carried out on this and related topics during the last decade or two, I felt it was still necessary to visualize this venture from two alternative ap proaches: (1) a more general one, which would cover the subject of calcium and the secretory process from a broad perspective, but of course not in great detail, and (2) a more specific one, restricting coverage to carefully defined limits but with comprehensive analysis of limited topics. The final course undertaken appears to lie somewhere between these two extremes."

Brain Neurosecretory Cytokines: Immune Response and Neuronal Survival summarizes the biological and chemical data of signal molecules of the brain neuroendocrine immune system, mainly proline-rich peptides, which play an important role in the regulation of immune response, neuronal survival, hematopoiesis, and adaptation. The author also describes the role of PRPs for the protection of neurons against neurodegenerative disturbances and diseases. Brain Neurosecretory Cytokines: Immune Response and Neuronal Survival will be of great aid to the researchers and students in various areas of neurobiological profile (neurochemistry, neuroendocrinology, neurophysiology, and endocrinology).

This book represents the proceedings from a conference that took place in Dallas in the spring of 1999 which was entitled "Pediatric Gender Assignment - A Critical Reappraisal". Some participants rightfully argued that the conference really focused on the issue of pediatric gender assignment, and that reassignment was not applied in most cases. Their comments were reflected in the title of this monograph. This multidisciplinary meeting was sponsored by a conference grant from the National Institutes of Health, and a broad inquiry into this complex topic took place from many points of view. Basic scientists offered insight into mechanisms of sexual differentiation of the gonads, physical phenotype and imprinting of the central nervous system. Endocrinologists reviewed their experience in diagnosis and management, surgeons described traditional as well as innovative approaches, and there was strong representation from the ethical and behavioral sciences. In putting together such a panel, it was essential that we identify a cast of speakers who could address their viewpoints with strong convictions, and yet not let their passions render the meeting counter productive. We were not disappointed. While many differing points of view were firmly expressed by the panelists and audience, all viewpoints were accorded the respect they deserved. The concept behind the meeting and this book really originated in 1997 shortly after Diamond and Sigmundson published their long term follow up study of the John/Joan case.

Ghrelin is a 28-amino acid acylated peptide predominantly produced by the stomach. It displays strong GH-releasing activity mediated by the hypothalamus-pituitary GH secretagogue (GHS)-receptors specific for synthetic GHS. Ghrelin also acts on other central and peripheral receptors and enables other actions including: stimulation of lactotroph and corticotroph secretion; food-intake; gastro-entero-pancreatic functions; metabolic; cardiovascular activity; and anti-proliferative effects. This volume aims to highlight the impact and function of the hormone ghrelin and provide insight to neuroendocrinologies and researchers interested in its molecular and clinical relevance.

During the last ten years, the diagnostic approach to disorders of bone and mineral metabolism has benefited considerably from the development of radioimmunoassay and competitive protein- binding techniques for measurements of circulating parathyroid hormone, calcitonin, and biologically active vitamin D me- tabolites. Accumulated experiences with radiogrametrical and densinometric methods of quantitating appendicular bone mass now facilitate the detection of changes in bone mineral content heretofore unrecognized by routine roentgenographic vertebral analysis. During this same decade, the diagnosis of metabolic bone disease and the skeletal response to remedial therapeutic ma- neuvers have also been facilitated by the routine application of the bone biopsy. Improvements in tinctorial techniques, stan- dardization in methodology essential for adequate preparation of thin undecalcified specimens, and the incorporation of tetracy- cline bone formation or mineralization "markers" should now herald the "routine" use of this diagnostic procedure. Moreover, the compilation and ready availability of reference morphometric data, spanning the prepubescent years charac- terized by skeletal growth and remodeling and the later senes- cent period during which bone loss normally proceeds in an un- 7 8 FOREWORD relenting fashion, allow adequate differentiation between normal age-sex-related changes in skeletal turnover attendant on skeletal maturation and aging and acquired or inherited de- rangements in bone metabolism.

Macromolecular (specifically peptide-based) drugs could potentially be highly effective medicines. However they have a relatively short duration of action and variable therapeutic index. An example of such a peptide is Glucagon-like Peptide I which could potentially be used as a revolutionary drug for diabetes. This is because it stimulates insulin only when the blood glucose level is high thereby reducing the risk of hypoglycemia (a significant disadvantage of using insulin is that an insulin overdose is the single most potent cause of life-threatening hypoglycemia). However it's short duration of action (half-life of 2 minutes in plasma) precludes its therapeutic use. In this volume, the use of novel therapeutics like GLP1 as an alternative to tradition insulin-based drugs in diabetes is described. Application of Peptide-Based Prodrug Chemistry in Drug Development elucidates the traditional concept of prodrugs as "specialized non-toxic protective groups used in a transient manner to alter or to eliminate certain limiting properties in the parent small molecule" (IUPAC definition). It goes on to provide insight into how prodrugs of peptides (with GLP1 as an example) could be appropriately used to extend the biological half life, broaden the therapeutic index of macromolecules and improve the pharmacodynamics of such drugs. Author explains the logic behind designing peptide prodrugs, synthetic procedures and bioassays to examine the conversion of the prodrug to the drug under therapeutic conditions. The prodrugs described slowly convert to the parent drug at physiological conditions of 37C and pH 7.2 driven by their inherent chemical instability without the need of any enzymatic cleavage. The diketopiperazine and diketomorpholine (DKP and DMP) strategies for prodrug conversion are demonstrated in detail with special emphasis on the chemical flexibility that it offers to develop prodrugs with variable time actions. This book will be of useful to chemists, biochemists, medicinal chemists, biologists and people in the medical profession (doctors). It may be used in undergraduate classes but will certainly help post-graduate students and advanced professionals. The author is grateful to Prof. Richard DiMarchi (Standiford H. Cox Professor of Chemistry and the Linda & Jack Gill Chair in Biomolecular Sciences at Indiana University) for valuable suggestions. The foreword for the book has been written by Prof. Jean Martinez, (Legion d'Honneur awarded by the French Republic; Professor of Chemistry and Medicinal Chemistry of the University of Montpellier, France; and Chairman of European Peptide Society, 2002-2010).

This book includes the most significant contributions of the First International Symposium on "Multiple risk factors in cardiovascular disease", chaired by Professors A. V. Chobanian (Boston), A. M. Gotto Jr. (Houston), c. Lenfant (Bethesda), R. Paoletti and A. Zanchetti (Milan), held in Washington DC, 10-12 December 1990, which focused on the risk factors for cardiovascular disease and their interactions. The need for this symposium is based on the epidemiological evidence that individuals from industrialized countries often possess two or more risk factors which synergically increase the global risk profile. The evidence that isolated vascular risk factors are not commonly found in high risk patients but more often a combination of risk factors are detected, is highlighted. Many recent epidemiological data identifying the intrinsic and environ mental factors contributing to the development of atherosclerosis are discussed. These results, in parallel to basic and clinical research, underline how atherosclerosis is a complex and multifac torial process involving the influences of lipid deposition, blood pressure, rheologic forces, carbohydrate tolerance, and thrombogenic factors (fibrinogen and platelets). Atherosclerosis is markedly accelerated by other risk factors, more so in the presence of concomitant hypercholes terolemia, hypertension, diabetes, upper body obesity. Furthermore, the risk associated with anyone of these risk factors varies widely depending on level of the associated atherogenic risk factors.

The selection of prolactin as the subject of the Midwest Con ference on Endocrinology was not only dictated by the recent ad vances in prolactin research but also by the long tradition in that particular area of Endocrinology in the laboratory of C.W. Turner at the University of Missouri. Therefore, it seems only appropri ate that these proceedings of the Tenth Midwest Conference on En docrinology are dedicated to the memory of this scientist, deceased in August 1975 before completion of this volume, whose pioneer in vestigations have contributed substantially to the advancement of our knowledge in many areas of Endocrinology and who played a major role in the early phases of prolactin research. This volume contains a review of the early studies in Turner's laboratory and the latest results obtained by some of the leading research workers in this area and should be a fitting memory to C.W. Turner. Some of the manuscripts printed here were prepared after the conference was held and include material of more recent origin. Much of the delay in publication was due to the length of time de voted to preparation of these manuscripts. To the other authors and participants, and to Plenum Press, we express our appreciation for their patience and cooperation. We also with to thank Mrs."

The past two decades have seen steady progress in our understanding of the pathogenesis of atherosclerosis. The role of low density lipoprotein (LOL) increase and of LOL receptor deficiency or malfunctions in familial hypercholesterolemia has been largely enlightened by the works of Brown and Goldstein. These authors postulated also that modification of LOL to a form recognized by the scavenger or acetyl-LOL receptor may be required for lipid loading of macrophage-derived foam cells in the lesions. A growing body of evidence suggests that oxidative modification of LOL could enhance its atherogenicity by its implication as a factor in the generation of foam cells. Thus, if the role of LOL in the pathogenesis of hypercholesterolemia was well established a great deal of information appears currently on new approaches such as the mechanisms leading to the accumulation of foam cells, the impact of LOL structural alterations, notably oxidation and the role of gene mutations of apolipoprotein Band/or LOL receptor The opening topic is devoted to these new avenues outlined in the field of hypercholesterolemia. The first part concerns the genetic aspects of atherosclerosis: mainly the genetics of apo 1 ipoprote ins , their transcriptional regulation, the amino acid mutations of the apo B gene and of the LOL receptor gene, the structural domains and the acylation sites of apoprotein B.

The 6th triennial meeting of the International Study Group for Tryp- tophan Research (ISTRY) was held May 9-12, 1989 in Baltimore, Maryland (USA). From the wide variety of topics and disciplines represented, as documented in this volume, it is clear that tryptophan research and ISTRY are alive and well. ISTRY traces its or1g1ns to at a tryptophan symposium organized in 1971 by H. Schievelbein at Hohenried near Munich (Germany). Up to that time there had been occasional international tryptophan conferences at irregular inter- vals. A number of participants at the Hohenried meeting felt that an inter- national tryptophan organization should be formed to organize regular meet- ings and to foster collaboration and information exchange on tryptophan-re- lated topics. Thanks mainly to the founding work of H. Schievelbein and W. Kochen, an executive committee was elected and ISTRY was born. The inaugural meeting in 1974 was held in Padova (Italy) to honor L. Musajo, one of the foremost pioneers in tryptophan studies. This first ISTRY meeting was suc- cessfully organized by L. Musajo, G. Allegri, A. De Antoni, and C. Costa, and was critical in assuring the viability of the new organization. Subsequent meetings were held in 1977 in Madison, Wisconsin (USA), organized by R.R. Brown, D.P. Rose, and W.E. Knox, honoring C.P. Berg; 1980 in Kyoto (Japan), organized by O. Hayaishi, R. Kido, Y. Ishimura, T. Deguchi, T. Hino, T.

Insulin pump therapy is now a well-established option for treating diabetes. This method of insulin delivery offers the opportunity for people with diabetes to manage their diabetes confidently and competently to achieve good glycaemic control and a better quality of life. "Using Insulin Pumps in Diabetes" covers all aspects of insulin pump therapy in a clear and informative style, and is an essential guide for all health professionals involved in caring for people with diabetes using insulin pumps.

"Using Insulin Pumps in Diabetes" explores issues such as the advantages and disadvantages of insulin pump therapy; the experiences of insulin pump users, how to set up an insulin pump service, how to set and adjust insulin doses and optimising glycaemic control. It also includes chapters on insulin pumps in pregnancy, and in babies, toddlers and young children.

We are especially grateful to Dr. Philip Corfman and his colleagues of the Population and Reproduction Grants Branch of NICHD for making this Conference possible. The format of this volume follows in general the order in which the papers were presented during the Conference. The Conference was divided into four sessions, each of which was presided over by a capable and distinguished scientist. Each of these chairmen, Drs. T. H. Hamilton, G. A. Puca, R. L. Vande Wiele and H. G. Williams-Ashman provided valuable discussion and for their services we are most appreciative. The Editors are indebted to Mr. Robert Colligan for his help in organizing and in redacting the manuscripts. A special commen dation is also extended to Ms. Mary Jane Fowler who cheerfully and efficiently typed this entire volume. Finally, we express thanks to the individual participants of the Conference for their cooperation and prompt submission of the manuscripts and to the Plenum Press for ensuring the rapid publica tion of this volume.

Most of us spend at least two-thirds of our lives either sitting or standing. It is somewhat surprising, therefore, to find not a single book devoted to disorders caused by derangements of the normal physiological adjustments to changes in posture. In fact, until very recently, medical students have not even been advised to measure the blood pressure and heart rate in the upright posture as part of the routine physical examination. Although Bradbury and Eggleston first described orthostatic hypotension as a consequence of autonomic insufficiency in 1925, interest in orthostatic disorders has been slow to develop in the subsequent years. It is well known that the change from recumbency to the standing posture stimulates neurological, endocrine, and cardiovascular adjustments that ensure maintenance of a normal circulation despite the effects of gravitational forces. The mechanisms of these physiological responses to orthostasis have been stud ied by many investigators. Some of the defects to which antigravitational com pensatory mechanisms are subject, such as postural hypotension resulting from autonomic failure, have been studied intensively and have become part of the general knowledge of most medical practitioners. Other orthostatic disorders such as various other postural abnormalities of blood pressure control, and orthostatic edema-have received far less attention and have been unable to compete with the more dramatic and life-threatening ailments of humankind for a place in our standard medical texts. These disorders often give rise to distressing symptoms and may lead to severe impairment of health.

The areas of experimental and clinical psychopharmacology have continued to grow in terms of the numbers of studies appearing in the literature as well as the activity generated by other disciplines that has influenced the output of behavioral pharmacology research. Psychoactive drugs have been considered for their comparative effects upon selected behaviors or for their effect upon diverse behaviors. Behavioral circum stances certainly influence not only the metabolism and action of psycho tropic drugs behaviorally, but also the disposition of these agents and/ or their metabolites in regions of the central nervous system. There can hardly be a psychopharmacology without a neuropharmacology, and the latter would seem to depend upon a neurochemistry. There would appear to be variables that exert potent influences upon the disposition and action of psychotropic drugs, that also relate quite directly to their effects upon behavior; these include drug interactions, nutritional status, environmental effects such as temperature, photic and tactile stimulation, and stress, and the basal status upon which such drug treatment is superimposed. In this volume of Current Developments in Psychopharmacology, which will be the last to appear in this format, we have sought to focus upon a series of current topical reviews that highlight representative areas of experimental and clinical research activity in psychopharmacology. In the first chapter, Dr. Lagerspetz reviews a frequently neglected aspect of psychopharmacological research-the actions of psychoactive agents upon the nervous system and behavior of non-mammalian species."
