Molecular and Cell Biology of Type 2 Diabetes and Its Complications


Book Description

The present volume summarizes current research on type 2 diabetes, its etiology, pathogenesis and long-term vascular and neurological consequences, with special emphasis on molecular and biochemical mechanisms. Alterations in insulin secretion are comprehensively treated, focusing on the role of glucokinase as glucose sensor. Moreover, insulin action is analyzed with regard to both nonoxidative glucose utilization and glucose oxidation. Concerning the complications in chronic diabetes, topics covered include the effects of high glucose concentration on cellular and endothelial functions and on the glucose phosphorylation rate in non-insulin-sensitive tissues. Furthermore, the role of oxidative stress and advanced glycation end products as well as the significance of alterations in lipoprotein structure are considered. Finally, the pericyte loss in retinopathy and microalbuminuria as related to cardiovascular risk are discussed. Taken as a whole, the contributions included in this book represent a large body of information that will be of great interest to diabetologists, endocrinologists and internists interested in both the basic and clinical aspects of diabetes and its complications.




Molecular Nutrition and Diabetes


Book Description

Molecular Nutrition and Diabetes: A Volume in the Molecular Nutrition Series focuses on diabetes as a nutritional problem and its important metabolic consequences. Fuel metabolism and dietary supply all influence the outcome of diabetes, but understanding the pathogenesis of the diabetic process is a prelude to better nutritional control. Part One of the book provides general coverage of nutrition and diabetes in terms of dietary patterns, insulin resistance, and the glucose-insulin axis, while Part Two presents the molecular biology of diabetes and focuses on areas such as oxidative stress, mitochondrial function, insulin resistance, high-fat diets, nutriceuticals, and lipid accumulation. Final sections explore the genetic machinery behind diabetes and diabetic metabolism, including signaling pathways, gene expression, genome-wide association studies, and specific gene expression. While the main focus of each chapter is the basic and clinical research on diabetes as a nutritional problem, all chapters also end with a translational section on the implications for the nutritional control of diabetes. - Offers updated information and a perspective on important future developments to different professionals involved in the basic and clinical research on all major nutritional aspects of diabetes mellitus - Explores how nutritional factors are involved in the pathogenesis of both type1 and type2 diabetes and their complications - Investigates the molecular and genetic bases of diabetes and diabetic metabolism through the lens of a rapidly evolving field of molecular nutrition







Molecular Biology of Diabetes


Book Description

In a rapidly evolving and extremely important area of medical science, it is often difficult for the student, teacher, and researcher to keep abreast of all the important advances. The purpose of Molecular Biology ofDiabetes, Parts I and II is to bring to these individuals the latest knowledge of diabetes-related research in a comprehensive, yet concise manner. To this end, we have assembled chapters, written by most of the world's experts in the field, that we believe compre hensively survey and synthesize a coherent understanding of the subject. Studies of the etiology of type I and type II diabetes are extremely exciting and essential, since we hope to one day prevent the disease using gene therapy. These aspects are covered in Molecular Biology of Diabetes: I. Autoimmunity and Genetics; Insulin Synthesis and Secretion. In type II diabetes, an abnormality in pancreatic secretion exists concomitantly with peripheral insulin resistance. This abnor mality of insulin secretion is believed to be related to a defect(s) in glucose sensing. Uncoupling of glucose sensing from insulin secre tion may be the crucial step in the pathogenesis of noninsulin-depen dent diabetes. In this volume, we have invited authors to describe their studies on all known factors affecting ~-cell function, including autoimmunity and genetics of diabetes, as well as molecular mecha nisms of insulin synthesis and secretion. In the last few years, the most rapidly advancing area of research in diabetes has been, in fact, related to insulin action.




Complement Regulatory Proteins


Book Description

From small beginnings in the early 1970s, the study of complement regulatory proteins has grown in the last decade to the point where it dominates the complement field. This growth has been fueled by the discovery of new regulators, the cloning of old and new regulators, the discovery that many of the regulators are structurally and evolutionarily related to each other and the development of recombinant forms for use in therapy. There are now more proteins known to be involved in controlling the complement system than there are components of the system and the list continues to grow. The time is ripe for a comprehensive review of our current knowledge of these intriguing proteins. This book does just that. The first few chapters discuss the "nuts-and-bolts" of the complement regulators, describing their structures, functional roles and modes of action. The roles of the complement regulators in vivo are then described, focusing on the consequences of deficiency, roles in the reproductive system, interactions with pathogens and exploitation for therapy. The interesting developments in defining the complement regulators expressed in other species are also discussed. The book is written as a monograph, albeit by two people. The text is as readable as possible without compromising on scientific accuracy and completeness. The conversational style very evident in some sections is deliberate! Placing all references in a single bibliography at the end of the text further improves readability. The reader will go to the book to discover a specific fact but be persuaded to read more and derive pleasure from the process. The authors' enthusiasm for the subject comes over strongly in the text, and this enthusiasm proves infectious. - Complement regulators--structure, functional roles and mode of action - Comprehensive reviews of each of the individual regulators - Roles of Complement regulators in vivo,in health and disease: - Consequences of deficiency - Roles in the reproductive system - Interactions with pathogens - Exploitation for therapy - Complement regulators in other species




International Textbook of Diabetes Mellitus


Book Description

The International Textbook of Diabetes Mellitus has been a successful, well-respected medical textbook for almost 20 years, over 3 editions. Encyclopaedic and international in scope, the textbook covers all aspects of diabetes ensuring a truly multidisciplinary and global approach. Sections covered include epidemiology, diagnosis, pathogenesis, management and complications of diabetes and public health issues worldwide. It incorporates a vast amount of new data regarding the scientific understanding and clinical management of this disease, with each new edition always reflecting the substantial advances in the field. Whereas other diabetes textbooks are primarily clinical with less focus on the basic science behind diabetes, ITDM's primary philosophy has always been to comprehensively cover the basic science of metabolism, linking this closely to the pathophysiology and clinical aspects of the disease. Edited by four world-famous diabetes specialists, the book is divided into 13 sections, each section edited by a section editor of major international prominence. As well as covering all aspects of diabetes, from epidemiology and pathophysiology to the management of the condition and the complications that arise, this fourth edition also includes two new sections on NAFLD, NASH and non-traditional associations with diabetes, and clinical trial evidence in diabetes. This fourth edition of an internationally recognised textbook will once again provide all those involved in diabetes research and development, as well as diabetes specialists with the most comprehensive scientific reference book on diabetes available.
