Calcium: The molecular basis of calcium action in biology and medicine


Book Description

The enormous and varied role of calcium in living systems is now widely appreciated by both cell biologists and clinicians. The identification and characterisation of new calcium binding proteins and regulatory pathways is matched by the recognition of the involvement of calcium binding proteins in a growing number of disease states. This book is intended to introduce clinicians to fundamental biological research, whilst at the same time attracting researchers to the clinical world. The publication of the book coincides with the elucidation of the complete Human Genomic Sequence. As a result of this, scientists now have access to an unprecedented array of data, from which new calcium binding proteins and hence new regulatory pathways will undoubtedly be discovered. It is a further aim of this book to provide a `key' to open the door to the new postgenomic era. The book is in three parts. The first section introduces the reader to the role of calcium in cell biology, providing an appreciation of how this small, simple, non-metabolisable agent can move rapidly and silently through the different cellular compartments, thereby influencing and controlling the fate of the cell. This section also illustrates and dissects the often-complex interplay between calcium and numerous agents in muscle and endocrine cells, neurons, hepatocytes, and platelets. In the second section the reader will discover the role of calcium and its partners in common diseases such as migraine and drug dependence. New classes of diseases such as annexinopathies, channelopathies, calcium-sensing disorders, and citrullinemia are discussed, and the authors give many new insights into the molecular mechanisms of the diseases, thereby explaining how and why they occur. Such information is clearly of primary importance for the pharmaceutical industry. New ideas and concepts of neurodegenerative diseases are introduced, which should stimulate new approaches. Clinicians will also have access, in a comprehensive and authoritative yet highly readable chapter, to data from recent large-scale clinical studies on the numerous and widely prescribed calcium antagonists. The final section gives information on new methods and devices for calcium imaging, and illustrates how calcium movement and change can be monitored and ingeniously utilised as a fast, cheap, and accurate drug screening instrument.

Calcium Orthophosphates


Book Description

Due to a great chemical similarity with the biological calcified tissues, many calcium orthophosphates possess remarkable biocompatibility and bioactivity. Materials scientists use this property extensively to construct artificial bone grafts that are either entirely made of or only surface-coated with the biologically relevant calcium orthophospha




Regulation of Bacterial Virulence


Book Description

A comprehensive compendium of scholarly contributions relating to bacterial virulence gene regulation. • Provides insights into global control and the switch between distinct infectious states (e.g., acute vs. chronic). • Considers key issues about the mechanisms of gene regulation relating to: surface factors, exported toxins and export mechanisms. • Reflects on how the regulation of intracellular lifestyles and the response to stress can ultimately have an impact on the outcome of an infection. • Highlights and examines some emerging regulatory mechanisms of special significance. • Serves as an ideal compendium of valuable topics for students, researchers and faculty with interests in how the mechanisms of gene regulation ultimately affect the outcome of an array of bacterial infectious diseases.




Calcium Entry Channels in Non-Excitable Cells


Book Description

Calcium Entry Channels in Non-Excitable Cells focuses on methods of investigating the structure and function of non-voltage gated calcium channels. Each chapter presents important discoveries in calcium entry pathways, specifically dealing with the molecular identification of store-operated calcium channels which were reviewed by earlier volumes in the Methods in Signal Transduction series. Crystallographic and pharmacological approaches to the study of calcium channels of epithelial cells are also discussed. Calcium ion is a messenger in most cell types. Whereas voltage gated calcium channels have been studied extensively, the non-voltage gated calcium entry channel genes have only been identified relatively recently. The book will fill this important niche.




Vasopressin and Oxytocin


Book Description

This monograph provides a comprehensive overview of recent advances in the field of vasopressin and oxytocin. In the summer of 1997, scientists from over 20 countries congregated in Montreal for the 1997 World Congress of Neurohypophysial Hormones, a conference that united the fields of vasopressin, neurohypophysis and oxytocin in a single joint meeting that gave rise to the present book. The organization of a joint meeting was prompted by several recent developments. Specifically the molecular characterization of the vasopressin/oxytocin receptor family made it mandatory to adopt an integrated view and to discuss the vasopressin/oxytocin ligand/receptor family as a whole. To ensure em phasis on novelty, the conference focused on advances made over the last two years and also included important contributions by scientists that had not previously been associated with the vasopressin/oxytocin field. Vasopressin and oxytocin are two neurohormones that exert a wide spectrum of cen tral and peripheral actions. Accordingly, the vasopressin/oxytocin field embraces a large number of different domains, ranging from neuroscience, endocrinology, and oncology to renal, reproductive, and cardiovascular physiology and pathology.




Phosphate Metabolism


Book Description

We present to our readers the proceedings of the Second International Workshop on Phosphate. A short account of the history of the effort led to the Phosphate Workshops is appro priate and can be of interest to the reader. The idea for Phosphate Workshops was born in the early days of November, 1974. One of us (S. G. M. ) suggested the thought to a group of scientists gathered for a luncheon in one of the attrac tive small restaurants in Weisbaden, Germany. The purpose of the workshop was to bring together interested scientists to discuss the newer developments and the recent advances in the field of phosphate metabolism and the other related minerals. An Organizing Committee made of Shaul G. Massry (USA), Louis V. Avioli (USA), Philippe Bordier (France), Herbert Fleisch (Switzerland), and Eduardo Slatopolsky (USA) was formed. The First Workshop was held in Paris during June 5-6, 1975 and was hosted by Dr. Philippe Bordier. Its proceeding was already published. The Second Workshop took place in Heidelberg during June 28-30, 1976 and was hosted by Dr. Eberhard Ritz. Both of these workshops were extremely successful scientific endeavors, and the need for them was demonstrated by the great interest they generated among the scientific community. The Or ganizing Committee, therefore, decided to continue with the tradi tion to hold additional Workshops annually or every other year.







Calcium in Biological Systems


Book Description

This volume is based in part upon the proceedings of the Calcium Theme held during the 67th Annual Meeting of the Federation of American Societies for Experimental Biology, which took place in Chicago, AprillO-lS, 1983. The American Society for Pharmacology and Experimental Therapeutics had the primary responsibility for organizing the scientific program with the assistance of other member societies, including the American Physiology Society, American Association of Pathologists, and American Institute of Nutrition. The purpose of the Calcium Theme was to review progress in the diverse areas of investigation bearing on the ubiquitous role of calcium in biological systems. In addition to contributions from those participating in the Theme, this volume also includes a number of invited papers that were added to fill certain voids in topics covered. The authors were selected because they are investigators active in the mainstream of their particular research area, possessing the acumen to analyze cogently not only their own recent findings but also to relate these findings to their respective area. New information as well as reviews of current concepts generally highlight the individual contributions. Undoubtedly, some readers may argue with the emphasis made and/or the conclusions reached on individual topics. In such cases, other volumes will hopefully provide a forum for alternative points of view. Due to the broad scope of subjects covered and the large number of contributions, the papers have been arranged in three sections.
