1 2 MARCEL B. ROBERFROID AND GLENN R. GIBSON 1 Universite Catholique de Louvain, Department of Pharmaceutical Sciences, Avenue Mounier 73, B-1200 Brussels, BELGIUM 2 Food Microbial Sciences Unit, Department of Food Science and Technology, The University of Reading, Reading, UK It is clear that diet fulfils a number of important human requirements. These include the provision of sufficient nutrients to meet the requirements of essential metabolic pathways, as well as the sensory (and social) values associated with eating. It is also evident that diet may control and modulate various body functions in a manner that can reduce the risk of certain diseases. This very broad view of nutrition has led to the development of foodstuffs with added "functionality." Many different definitions of functional foods have arisen. Most of these complicate the simple issue that a functional food is merely a dietary ingredient(s) that can have positive properties above its normal nutritional value. Other terms used to describe such foods include vitafoods, nutraceuticals, pharmafoods, foods for specified health use, health foods, designer foods, etc. Despite some trepidation, the concept has recently attracted much interest through a vast number of articles in both the popular and scientific media.

Neuroscience Perspectives provides multidisciplinary reviews of topics in one of the most diverse and rapidly advancing fields in the life sciences. Whether you are a new recruit to neuroscience, or an established expert, look to this series for 'one-stop' sources of the historical, physiological, pharmacological, biochemical, molecular biological and therapeutic aspects of chosen research areas. The sigma receptor was originally thought to be a subset of the opioid receptor family, and it is less than 10 years since it was recognized that this receptor represents unique binding sites in mammalian brain and peripheral organs, distinct from any other known neurotransmitter receptor. Since the sigma receptors exhibit high affinity for members of diverse classes of psychotropic drugs, and have been postulated to be involved in various central nervous disorders, neuroscientists have demonstrated a great deal of interest in the elucidation of these receptor sites and their biological relevance. Relatively little is known about the precise role of sigma receptors in normal brain function and in CNS disorders, despite an overwhelming research effort. This research has resulted in many controversies, some of which have been reconciled while others have not. This volume aims to update the reader on the current situation, and deals with the potential functional significance of these receptors in the brain and peripheral organs and, where appropriate, makes reference to the clinical potential of these sites.

In one generation, the numerous factors involved in blood coagulation have become real protein entities, isolated in pure form, expressed by recombinant DNA techniques, and subjected to structure elucidation by the modem methods of physical chemistry, viz. , X-ray diffraction, and NMR, ESR and fluorescence spectroscopy. The major milestone in this field was the breakthrough achieved by W. Bode, R. Huber and their colleagues in 1989 in of human a-thrombin, inhibited with D-Phe-Pro-Arg determining the crystal structure chioromethyl ketone. The availability of this structure will greatly facilitate the interpretation of experiments designed to gain an understanding of the interatomic interactions between this enzyme and fibrinogen and its other substrates. At the same time, it provides a rational basis for the design and synthesis of inhibitors of thrombin, the subject of this symposium. The symposium was organized in four sessions: (1) Structural features of the interaction of thrombin with substrates and inhibitors, (2) Synthetic inhibitors, (3) Hirudin and its analogues, and (4) Pharmacological and clinical considerations. This book contains summaries of most of the papers presented, and takes its rigbful place among two others that provide a comprehensive picture of our current knowledge about thrombin, viz. the 1977 volume entitled "Chemistry and Biology of Thrombin", edited by R. L. Lundblad, J. W. Fenton II, and K. G. Mann, and the 1992 volume entitled "Thrombin: Structure and Function", edited by L. J. Berliner.

That precursors of adult coronary artery disease, hypertension, and type II diabetes begin in childhood have been clearly established by the Bogalusa Heart Study. This unique research program has been able to follow a biracial (black/white) population over 35 years from childhood through mid-adulthood to provide perspectives on the natural history of adult heart diseases. Not only do these observations describe trajectories of cardio-metabolic risk variables leading to these diseases but provide a rationale for the need to begin prevention beginning in childhood. The trajectories of the burden of cardio-metabolic risk variables in the context of their fetal origin and chromosome telomere dynamics provide some insight into the metabolic imprinting in utero and aging process. The observed racial contrasts on cardio-metabolic risk variables implicate various biologic pathways interacting with environment contributing to the high morbidity and mortality from related diseases in our population. To address the seriousness of the onset of cardiovascular disease in youth, approaches to primordial prevention are described focussing on childhood health education as an important aspect of Preventive Cardiology.

Many advances have been made in the field of thermoregulation in the past few years. These include our understanding of Fever, which is now considered not simply a rise in deep body temperature foHowing infection, but just one aspect, though perhaps the most easily measured, of the Acute Phase of the Immune Response. Classification and identification of the Cytokines and the availability of recombinant material has greatly aided this research. Similarly, our understanding of the Hypothalamo-Pituitary Adrenal Axis has altered our way of thinking about temperature regulation. Of importance are the problems associated with adverse climatic conditions and survival, and the problems encountered by the neonate and the hibernator. At the biochemical level, our knowledge of the control of heat production and the role of brown adipose tissue is rapidly advancing. All these issues and many others were discussed at a Symposium 'Thermal Physiology 1993' held in Aberdeen, Scotland in August 1993 under the auspices of the Thermal Physiology Commission of the International Union of Physiological Sciences. Six main aspects of the subject of temperature regulation are included in this book, namely, Fever (including the Acute Phase of the Immune Response and Thermoregulatory Peptides), Neurophysiology of Thermoregulation, Neonatal Thermoregulation, Mechanisms of Heat Production, Ecological and Behavioural Thermoregulation, and Emerging Themes in Thermoregulation.

The molecular basis for the physiology of the brain has advanced enormously in the past twenty years with an influx of new information gleaned through technological developments in neuroimaging and molecular discoveries. Molecular Physiology and Metabolism of the Nervous System, authored by Gary A. Rosenberg, an authority on the physiology of brain fluids and metabolism, combines the classic physiology that dates back to the beginning of the nineteenth century with the advances in molecular sciences, providing a strong framework for understanding the diseases that are commonly treated by neurologists.
Molecular Physiology and Metabolism of the Nervous System focuses on the current neuropathology and implications of cerebrospinal fluid diseases and diseases of the blood-brain barrier: how the two affect stroke, infection, brain tumors, and increased intracranial pressure. The book discusses the effects of blood flow in stroke and dementia, the disruption of the blood-brain barrier in neuroinflammation, and the dysfunction due to brain edema and increased intracranial pressure.
Molecular Physiology and Metabolism of the Nervous System is necessary reading for neurologists, neuroscientists, and residents in neurology, neurosurgery, and psychiatry, giving them a strong grounding in physiology and metabolism that will aid them in diagnosis and treatment.

As a research subject, the biomechanics of the urinary bladder are relatively young, yet medical problems associated with them are as old as mankind. Offering an update on recent achievements in the field, the authors highlight the underlying biological, chemical and physical processes of bladder function and present the systematic development of a mathematical model of the organ as a thin, soft biological shell. The book will be a valuable resource for postgraduate students and researchers interested in the applications of computational mathematics and solid mechanics to modern problems in biomedical engineering and medicine.

The objective of this book is to provide the researcher and clinician with the recent developments in the analysis and assessment of cardiovascular func tion. The chapters are organized into sections that correspond with the various anatomical levels of the cardiovascular system. To a large extent, recent focus on the cardiovascular system function has been directed at the molecular level to the near exclusion of the tissue and organ function. While this may be useful in developing new therapeutic drugs, it does not aid the cardiologist or surgeon, who routinely deal with patient symptoms. This book integrates the micro-level and organ-level function so that new infor mation may be assimilated into the cardiovascular system as a whole. Within each section, the chapters have been arranged to progress from recent theoretical developments, to experimental research, and finally to clinical applications. This approach facilitates the timely transfer of infor mation from basic research to the clinic. The strength of the analytical approach will be evident to the reader. The theoretical analysis offers guidance to experimental design and, in some cases, offers solutions where measurements are as yet unattainable. In moving from newly attained knowledge to clinical practice, this book emphasizes the noninvasive meth in the future as technological advances ods. Such methods are desirable occur and the trend towards early preventive diagnosis is sought. What follows are highlights of new developments covered in each section of the book."

The Taurine Symposium- "Taurine: Beginning the 21'' Century"- was held September 20-23, 2002, on the beautiful island of Kauai in Hawaii. The headquarters of the meeting was the Radisson Kauai Beach Resort. This international meeting was attending by approximately 80 individuals from 23 nations and 4 continents. Seventy-five papers were presented either as platform presentations or poster presentations. Taurine, first isolated from ox bile in 1827 by Tiedemann and Gmelin and named in 1838 by Demarcay, became of significant scientific interest in 1968 when the first extensive review article was published by Jacobsen and Smith. Interest in taurine grew exponentially after 1975 when the first taurine symposium was organized by Ryan Huxtable in Tucson, Arizona. Since that date, taurine symposia have been held approximately every two years held in various cities and resort areas around the world. Taurine investigators have had the privilege of attending these scientific meetings on three continents - Asia, Europe, and North America. Since the initial meeting in 1975, a central question addressed during many of the symposia has been: "What is physiological, pharmacological, nutritional, and pathological role of taurine?." Although taurine has been established as an important osmolyte, it appears to affect many other biological processes. However, the exact mechanism(s) by "which taurine acts" has not yet been definitively answered. In Kauai, the patticipants discussed many topics and asked many questions regarding the role and actions of taurine.

This book focuses on all of the major problems associated with the absence of body weight in space, by analyzing effects, adaption, and re-adaptation upon returning to Earth, using sound scientific principles embedded in a historical context. Serious problems for space travelers range from Space Motion Sickness (SMS) to recently discovered ocular effects that may permanently impair vision. Fluid loss and shifts, spinal changes, and bone and muscle loss are also all results of weightlessness. Starting with a brief definition and history of weightlessness, the authors then address in detail each problem as well as the countermeasures aimed at alleviating them. In some cases, alternative hypotheses regarding what can and should be attempted are also presented. As plans for long-term missions to the Moon and Mars develop, it will be essential to find countermeasures to weightlessness that are effective for missions that could span years.

Ion channels are the major class of membrane proteins responsible for rapid and regulated transport of ions across biological membranes and for the generation and propagation of electrical signals in the brain, heart, and skeletal and vascular tissues. Ion channels are also known to play critical roles in regulation of cell proliferation, insulin secretion and intracellular signaling in a variety of cell types. This book focuses on the roles of ion channels in vascular tissues under normal and pathological conditions. Vascular abnormalities are known to underlie a plethora of severe pathological conditions, such as atherosclerosis, systemic and pulmonary hypertension, coronary or cerebral vasospasm, and diabetes. In addition, misregulated angiogenesis is one of the major contributors to the development of tumors. Therefore, it is clearly imperative to obtain a better understanding of the molecular mechanisms that contribute to vascular disorders. This book will be the first comprehensive assembly of assays to present the studies that have been done during the last decade to elucidate the roles of ion channels in different vascular diseases.

Proceedings of the 5th Biannual International Meeting on Angiogenesis: From the Molecular to Integrative Pharmacology, held July 1-7, 1999, in Crete, Greece. Angiogenesis, as a vastly complex biological process, has challenged researchers from all basic scientific disciplines, including pharmacology, biochemistry, physiology, embryology and anatomy. The significance of this phenomenon for the study of disease states has also interested clinicians from a number of specialist fields. This multidisciplinary work reflects the growth of awareness of concepts such as angiogenesis based therapy, the enormous therapeutic and commercial potential of which has attracted major research and investment in recent years. This volume, which aims to bridge the gap between basic and clinical methodology and understanding, presents the most up-to-date developments in this field.

Following systematic development of technical aspects and physiological understanding, and clinical applicability of cardiac autonomic testing, this book provides a detailed guide to performing individual autonomic tests in both research and clinical settings. The book is structured in three parts covering the physiological background of cardiac autonomic regulations, description of technology and interpretation of individual autonomic tests, and applicability of the individual tests under various clinical circumstances and in defined populations of patients. The book is intended to serve both research and clinical cardiologists as well as research and clinical specialists of other medical fields who use the assessment of cardiac modulations to investigate the autonomic nervous system.

During several decades of this century, the classical physiological studies on the cardiovascular system have greatly improved our knowledge on the function of this system under normal and pathological conditions. This knowledge was the basis of the breakthrough for diagnostic techniques like the Swan-Ganz catheter, coronary arteriography, left and right heart biopsies, and invasive measurements of contractility, as well as therapeutic tools including aortocoronary bypass surgery, percutanous transluminal coronary angioplasty, and a broad field of pharmacological interventions for the whole spectrum of cardiovascular diseases, especially chronic heart failure. It was during the last decade that the scientific world focused on the evolution of molecular biology of the cardiovascular system so that cardiovascular physiology seemed to become less important. Regarding the myocardium, molecular alterations of important functional proteins (phenotype changes), as well as signal transduction pathways of contractility and cardiac growth have been elucidated. The functional importance of a number of genes has undoubtedly been proven with the help of transgenic animals. Mechanics and Energetics of the Myocardium provides an overview for those researchers and practioners interested in the broad field of molecular biology and physiology of the cardiovascular system.

As humans ventured into the twentieth century, the industrialized countries were confronted with the scourge of rickets. Although solariums were becoming common in the early 1900s and phototherapy was gaining popularity as a result of the awarding of a Nobel Prize to Finsen in 1903, it wasn't until 1921 when Hess and Unger demonstrated that rickets could be cured by exposure to sunlight that the healthful benefit of sun exposure appreciated. In 1941, Apperly (Cancer Research; 1: 191-195, 1941) noted that the occasional increased risk of skin cancer was associated with a decreased risk of many other more common and serious cancers. The alarming increase in the number of cases of skin cancer, especially melanoma, has caused great concern about the negative role of sunlight in health. The Sixth International Arnold Rikli Symposium on the Biologic Effects of Light was held in Boston, Massachusetts from June 16th - 18th, 2001. The goal of this Symposium was to focus on the very popular practice of tanning either by sunlight or by artificial light sources and the overall impact this practice has on health and disease. The program was organized by members of the Scientific Advisory Committee and my co-chair emeritus, Professor Ernst G. Jung. The Program Committee organized an outstanding state-of-the-art program that was enthusiastically received by the participants.

This book tackles the role of interrelated conditions in the manifestation and course of pulmonary ailments. The articles run the gamut from basic to clinical science on such topics as airway allergy challenges, pulmonary dysfunction due to exposure to environmental pollution, molecular and functional aspects of smoking in lung carcinogenesis and in obstruction-related respiratory disorders, and others. Attention is directed to the developments in rehabilitative and lifestyle interventions in chronic disabilities, particularly involving neuromotor and stress-related conditions which, with advancing age, may lead to the deterioration of ventilation, with hypoxic sequelae. Enhanced research and awareness concerning the lung health drive better treatments and quality of life. Clinical insights presented in the book underscore a major role played by the science in transmuting biomedical knowledge into a better patient management. The volume is addressed to clinicians, researchers, physiotherapists, and other healthcare professionals engaged in effective patient care and therapy.

The Springer Handbook of Auditory Research presents a series of com prehensive and synthetic reviews of the fundamental topics in modern auditory research. It is aimed at all individuals with interests in hearing research including advanced graduate students, postdoctoral researchers, and clinical investigators. The volumes will introduce new investigators to important aspects of hearing science and will help established inves tigators to better understand the fundamental theories and data in fields of hearing that they may not normally follow closely. Each volume is intended to present a particular topic comprehensively, and each chapter will serve as a synthetic overview and guide to the literature. As such, the chapters present neither exhaustive data reviews nor original research that has not yet appeared in peer-reviewed journals. The series focusses on topics that have developed a solid data and con ceptual foundation rather than on those for which a literature is only beginning to develop. New research areas will be covered on a timely basis in the series as they begin to mature."
