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.

With contributions by numerous experts

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.
