An essential element in the development and functional integrity of all organisms is intercellular communication. This is achieved by the secretion of soluble messenger molecules which subsequently interact with receptor-effector pathways in the responsive cells. Hormones are traditionally defined as chemical messengers synthesized by endocrine glands. Unlike hormones produced by endocrine glands, growth factors are hormone-related substances produced by many tissues and play an important role in controlling growth and development. While the exact physiological roles of growth factors have yet to be elucidated, they play important roles in the regulation of cellular proliferation and/or differentiation during ontogenesis, growth and differentiation. During recent years there has been a substantial increase in research related to peptide growth factors, their receptors, and modes of action. With the discovery and characterization of numerous growth factors, it became clear that these growth factors had multiple features in common with classic hormones as well as with oncogenes. Furthermore, there are distinct families of growth factors based either on structural or functional similarities.

It has been over 50 years since Hans Selye formulated his concept of stress. This came after the isolation of epinephrine and norepinephrine and after the sympathetic system was associated with Walter Cannon's "fight or flight" response. The intervening years have witnessed a number of dis coveries that have furthered our understanding of the mechanisms of the stress response. The isolation, identification and manufacture of gluco corticoids, the identification and synthesis of ACTH and vasopressin, and the demonstration of hypothalamic regulation of ACTH secretion were pivotal discoveries. The recent identification and synthesis of CRR by Willie Vale and his colleagues gave new impetus to stress research. Several new concepts of stress have developed as a result of advances in bench research. These include the concept of an integrated "stress sys tem," the realization that there are bi-directional effects between stress and the immune system, the suggestion that a number of common psychiatric disorders represent dysregulation of systems responding to stress, and the epidemiologic association of stress with the major scourges of humanity."

Unraveling the functional properties of structural elements in the brain is one of the fundamental goals of neuroscientific research. In the cerebral cortex this is no mean feat, since cortical areas are defined microstructurally in post-mortem brains but functionally in living brains with electrophysiological or neuroimaging techniques - and cortical areas vary in their topographical properties across individual brains. Being able to map both microstructure and function in the same brains noninvasively in vivo would represent a huge leap forward. In recent years, high-field magnetic resonance imaging (MRI) technologies with spatial resolution below 0.5 mm have set the stage for this by detecting structural differences within the human cerebral cortex, beyond the Stria of Gennari. This provides the basis for an in vivo microanatomical brain map, with the enormous potential to make direct correlations between microstructure and function in living human brains. This book starts with Brodmann's post-mortem map published in the early 20th century, moves on to the almost forgotten microstructural maps of von Economo and Koskinas and the Vogt-Vogt school, sheds some light on more recent approaches that aim at mapping cortical areas noninvasively in living human brains, and culminates with the concept of "in vivo Brodmann mapping" using high-field MRI, which was introduced in the early 21st century.

From the 40th annual conference of the International Society on Oxygen Transport to Tissue (ISOTT), held in Bruges, Belgium in August 2012, this volume covers aspects of clinical applications, muscle oxygenation, cancer, measurement technologies, oxygen transport modelling and Near-Infrared Spectroscopy (NIRS), cell metabolism and brain oxygenation. Each topic was presented by one or two invited speakers, and a series of contributed talks.

Investigations involving incisive mechanistic dissection of various types of synaptic plasticity have revealed that it plays key roles in neural development, sensory information processing, cortical remapping following brain injury, perception, and behavioral learning and memory. Disruptions of synaptic plasticity may underlie neurological and behavioral disorders such as Alzheimer disease, Fragile-X syndrome, autism, and drug addiction. Multidisciplinary Tools for Investigating Synaptic Plasticity, therefore, assembles expert contributions that highlight techniques and strategies used in probing the cellular and molecular mechanisms of synaptic plasticity in the nervous systems of vertebrate and invertebrate species. Divided into three sections, this meticulous volume describes biochemical and genetic strategies for studying synaptic plasticity, behavior, neural development, and synaptogenesis, and also includes cellular electrophysiological and optical methods for interrogating a diverse array of mechanistic issues. As part of the Neuromethods series, this book contains the kind of detail and key implementation advice that maximizes successful results. Authoritative and invaluable, Multidisciplinary Tools for Investigating Synaptic Plasticity serves as an ideal primer for introducing researchers to specific techniques that will enhance their success at addressing novel questions in synaptic plasticity at the lab bench.

Taurine, or 2-aminoethane sulfonic acid, has long been known to be the major organic product formed from the breakdown of the sulfur-containing amino acids, methionine and cysteine. It is excreted as such in the urine or as bile acid conjugates in the bile. Research over the last 25 years, however, has uncovered an amazing variety of phenomena involving taurine. Despite the fact that the mechanism of action of taurine in some of these phenomena remains to be elucidated, it is clear that taurine is of far more physiological relevance than being the mere metabolic debris of sulfur amino acid catabolism. It also has numerous pharmacological actions that are beginning to be developed, as exemplified by some of the studies reported in this volume. This volume reports the proceedings of the latest of a series of international symposia, continuing on from the initial meeting held in Tucson, Arizona, in 1975. The latest symposium was the first to be held in Germany, in Cologne from August 29 through September 1, 1993. It continued the multidisciplinary approach that has been the norm for taurine symposia. We hope the publication of the proceedings will stimulate further investigations on this simple but fascinating compound.

This book dealing with stance and motion was planned in June 1986 at a meeting held in Moscow and Leningrad between a group of Soviet and French scientists interested in motor control. This meeting took place in the framework of an exchange program between the USSR Academy of Seiences and the French Centre National de la Recherche Scientifique. It was very successful event and was greatly appreciated by all those who attended it. Several participants put forward the proposal that the possibility of publishing a book was worth exploring. What were the reasons for publishing a book on stance and motion ? The interest aroused in the participants by each others contributions was not a sufficiently decisive argument. It was feit, however, that a large proportion of the orginal material presented at the meeting, especially in the field of posture and locomotion but also on other aspects covered by the book could be presented in a summarized form which should appeal to a larger audience because the facts and hypotheses they contained especially those from the Soviet participants, were not very familiar among international circles, and that many scientists would appreciate having a single volume containing a survey ofthe current state of research in this field. This was also the opinion of Plenum Press, who agreed to publish the book. Each participant at the meeting submitted a paper which was examined by two referees before being accepted.

Most of the following chapters were presented as plenary lectures or symposium talks at the 1986 XXXth Congress of the International Union of Physiological Sciences in Vancouver, B.C. A distinguished international group of endocrinologists and physiologists have contributed up-to-date reviews of their particular fields. The early chapters are largely concerned with the brain and neuroendocrine mechanisms controlling the secretion of gonadotropin releasing hormone (GnRH) and its action on the anterior pitui- tary gland. Later chapters focus on the gonads themselves and the systemic and intrinsic hormones influencing the functional cytology of ovarian and testicular cells. Such comprehensive subjects as sex differentiation, puberty, placentation and parturition are also discussed authoritatively. According to Pfaff and Cohen and Arai et al., gonadal steroids, especially estrogen, exert multiple effects on certain hypothalamic and preoptic neurons, including growth, protein synthesis and electrical changes, which promote plasticity and facilitate synaptogenesis. The electrophysio- logy of the hypothalamic GnRH pulse generator in the rhesus monkey is reviewed more specifically by Knobil. In ovariectomized ewes, Clarke finds both positive and negative effects of estrogen on hypothalamic release of GnRH as well as on pituitary responsiveness to the peptide. Flerk6 et al.

"Research into gastrointestinal motility has received renewed interest in part due to recent advances in the techniques for measuring the structure and function of gastrointestinal cells, tissue and organs. The integration of this wealth of data into biophysically based computation models can aid in interpretation of experimental and clinical measurements and the refinement of measurement techniques."

"The contents of this book span multiple scales - from cell, tissue, organ, to whole body and is divided into four broad sections covering: i) gastrointestinal cellular activity and tissue structure; (ii) techniques for measuring, analyzing and visualizing high-resolution extra-cellular recordings; (iii) methods for sensing gastroelectrical activity using non-invasive bio-electro-magnetic fields and for modulating the underlying gastric electrical activity and finally (iv) methods for assessing manometric and videographic motility patterns and the application of these data for predicting the flow and mixing behavior of luminal contents by using computational fluid dynamic techniques. "

"This book aims to provide both an overview of historical and existing research techniques as well as to highlight future directions and challenges for the community as a whole. It will be suitable for clinicians to understand the cellular and biophysical underpinnings of gastric emptying, gastroenterologists, surgeons, bioengineers and all scientists with interests in gastrointestinal motility research."

Regulated turnover of extracellular matrix (ECM) is an important component of tissue homeostasis. In recent years, the enzymes that participate in, and control ECM turnover have been the focus of research that touches on development, tissue remodeling, inflammation and disease. This volume in the "Biology of Extracellular Matrix" series provides a review of the known classes of proteases that degrade ECM both outside and inside the cell. The specific EMC proteases that are discussed include cathepsins, bacterial collagenases, matrix metalloproteinases, meprins, serine proteases, and elastases. The volume also discusses the domains responsible for specific biochemical characteristics of the proteases and the physical interactions that occur when the protease interacts with substrate. The topics covered in this volume provide an important context for understanding the role that matrix-degrading proteases play in normal tissue remodeling and in diseases such as cancer and lung disease.

This book covers all aspects of oxygen delivery to tissue, including blood flow and its regulation as well as oxygen metabolism. Special attention will be paid to methods of oxygen measurement in living tissue and application of these technologies to understanding physiological and biochemical basis for pathology related to tissue oxygenation. This book is multidisciplinary and designed to bring together experts and students from a range of research fields including biochemical engineering, physiology, microcirculation, and hematology.

In addition to its metabolic and endocrinologic effects, obesity and adipose tissue have now been shown to be associated with low grade inflammation resulting in cellular and humoral inflammatory factors of which the latter may act by endocrine, paracrine and autocrine mechanisms. These inflammatory mediators have increasingly been suggested as contributing to the obesity link to carcinogenesis and cancer promotion.

This volume of Energy Balance and Cancer will focus on recent developments and cutting edge research pointing to inflammation and inflammatory factors as key mediators of this linkage. The volume first provides information on inflammation as an important link between obesity and insulin resistance, which is in itself linked to promotion of cancer through hyperinsulinemia. The volume then covers some of the most important mechanisms by which obesity leads to inflammation, including the novel inflammasome concept, alterations in chromatin structure, circulating inflammatory factors, unique cellular interactions between adipocytes and macrophages and the direct link of dietary fat to inflammation and cancer.

Overall, this volume will provide important insight to help understand how inflammation may help modulate the linkage between obesity and cancer and serve as a platform for developing future research in this area.

This volume is the third in a series entitled" Advanced Methods of Physiological System Modeling" and the fifth in a series of research volumes published by Plenum under the sponsorship of the Biomedical Simulations Resource (BMSR) at the Uni versity of Southern California in the context of dissemination activities supported by the Biomedical Research Technology Program of the National Center for Research Resources at the National Institutes of Health under Grant No. P41 RR-OI861. These volumes are edited by BMSR principal scientists and report on recent research de velopments in the area of physiological systems modeling, as well as on advanced methods for analysis of physiological signals and data. As in the previous two volumes of this series, the work reported herein is con cerned with the development of advanced modeling methodologies and their novel application to problems of biomedical interest, with emphasis on nonlinear aspects of physiological function. The term "advanced methodologies" is used to indicate that the scope of this work extends beyond the ordinary type of analysis, which is confined traditionally to the linear domain. As the importance of nonlinearities in understanding the complex mechanisms of physiological function is increasingly recognized, the need for effective and practical modeling methodologies that address the issue of nonlinear dynamics in life sciences becomes more and more pressing.

This book provides the reader with a contemporary and comprehensive overview about the molecular, cellular and system-wide principles of circadian clock regulation. Emphasis is placed on the importance of circadian clocks for the timing of therapeutic interventions.

The function of the vascular system is to transport oxygen and nutrients to the cells and to remove carbon dioxide and metabolites. It also transports hormones and locally produced neurohumoral substances which, in part, regulate its own function. These interrelationships are essential to homeostasis. The vascular system is not an assembly of simple (elastic) tubes but a dynamic system with many external and intrinsic regulatory mechanisms. The endothelium plays a major role in the intrinsic regulation of the system. The system is also often subject to disease processes of which atherosclerosis is the most important. As a result of atherosclerosis, and other disease processes, replacement of vessels with prosthetic devices may be required to reestablish adequate tissue blood flow. It is therefore imperative to gain insight into the details of vascular function, especially the dynamics, and the endothelium, the processes of atherosclerosis development, the vascular prosthetic possibilities and, last but not least, the interrelationships between these sub-specialties.

The most relevant tools for visualizing metal ions in the cell and the most suitable bioinformatic tools for browsing genomes to identify metal-binding proteins are also presented. Thus, MILS-12 is of relevance for structural and systems biology, inorganic biological chemistry, genetics, medicine, diagnostics, as well as teaching, etc.

Herbert Henri Jasper is a scientist whose research activities have initiated and encompassed many of the major themes of neuroscience. He has pioneered in single unit recording, chronic neuronal studies, neurochemistry, electroencephalography, and many other disciplines. His students now hold important positions in universities and hospitals around the world. From July 21 to 23, 1986, a symposium entitled Neurotransmitters and Cortical Function: From Molecules to Mind was held in Montreal to honor Professor Jasper and to continue his pioneering efforts. The following chapters originated in that meeting. They summarize the current v vi PREFACE status of our knowledge in some of the fields influenced by Professor Jasper. They share a focus on neurotransmitters in cortical function, where we presume higher mental events originate. Professor Jasper has made contributions to the understanding of three different classes of neuro transmitters: GABA, acetylcholine, and catecholamines. It is an interest in trying to link neu rochemical events to some aspects of complex brain function and behavior that has characterized his work, and it is this philosophy that led to the present symposium to honor him. We dedicate this volume to Professor Jasper and the integrative approach that he has fostered. The Editors Montreal Contents 1. H. H.

The chapters of this book report cutting-edge research on molecular events in adiposity and type 2 diabetes, thus opening the way for innovative drug-based therapeutic strategies. It addresses all those who wish to keep in touch with recent developments in the field.

On December 6, 1961, a contract was signed by which the research institute of the Wander AG in Freiburg became the Max-Planck-Institut fUr Immunbiologie. The transfer of ownership took place during a happy expansion phase of the Max-Planck Society in which a growing economy in Germany allowed the foundation of many new research institutes by the Max-Planck-Society and other organizations. Nevertheless, it was a remarkable event. The acquisition by an academic organization of an institute formerly operated by an industrial company was rather unusual, not to speak ofthe fact that not only the facilities but also the entire scientific personnel were taken over. Retrospectively, the 40 years of the institute in the Max-Planck Society can be divided into 2 very different phases of 20 years each. The first 20 years were characterized by a continuation of the research that had begun in the Wander institute and centered on the structure and function of the bacterial compound endotoxin. During the second 20 years, the institute more than doubled in size and developed into an interdisciplinary research center that focuses on the development and organization of multicellular systems by combining studies in two fields of research: immunology and developmental biology. th The 40 anniversary of the foundation of the Max-Planck-Institute was celebrated by a ceremony including a scientific symposium. The first part of this volume presents the lectures given at the symposium by six leading biologists."

Obesity is currently regarded as one of the major health challenges of the developed world. Excess body weight is an important risk factor for morbidity and mortality from cardiovascular diseases, diabetes, cancer, musculoskeletal disorders and even psychiatric problems and is estimated to cause nearly 3 million deaths per year worldwide. Obesity is not necessarily associated with comorbidities: there are indeed metabolically healthy obese individuals. Thus, we need to consider individuals presenting simple with obesity separately from those at risk of developing or who have already developed complex clinical states potentially leading to disability. Comorbidities can tip the balance of independence in patients who already have functional limitations mainly due to the excess of mass itself or who develop conditions such as diabetes, cardiovascular conditions, non-alcoholic fatty liver disease, where an abnormal metabolism of adipose tissue prevails. Morbid obesity with comorbidities leading to disability represents a real social and economic burden for National Health Systems worldwide. The presence of multiple and associated comorbidities often represents an obstacle to being admitted to hospitals for the treatment of metabolic diseases. On the other hand, clinical units with optimal standards for the treatment of pathological conditions in normal-weight patients are often structurally and technologically inadequate for the care of patients with extreme obesity. The aim of this book is to focus on the pathophysiological and rehabilitative aspects of disabling obesity, highlighting multidisciplinary rehabilitation interventions as key to counteracting the disabling aspects of complicated obesity.

Regeneration, the homeostatic ability to maintain tissue structure in the face of normal cell turnover or loss of tissue damaged by trauma or disease, is an essentialdevelopmental process that continues throughout life. As recently as a decade ago, any serious discussion of the possibility of regeneration becoming a practical medical tool in the near future had the air of science fiction or over-optimistic speculation. The term regenerative medicine was certainly on many lips but few actually expected to soon see it applied in a clinical setting. A tidal wave of discovery has changed that and investigating the cellular mechanisms of natural regeneration has become one of the hottest topics in developmental biology and biomedicine in general. Many researchers entering the field find that the regeneration literature is still quite diffuse perhaps owing to the disparate biological systems that have been the object of study including hydra, planaria, newts, axolotls and more recently several mouse strains. The volume editors believe that an attempt to organize or systematize the literature is long overdue. In this volume, respected experts highlight the latest findings in vertebrate (including mammals) wound healing and regeneration. They present eleven reviews that cover a wide range of topics, from wound repair and its relationship to regeneration, through systems including lenticular, neural, and musculoskeletal tissues and limbs, to epigenetics and the role of the cell cycle. Nuclear reprogramming and cellular plasticity, which open the door for potential regenerative medical therapies for injury and degenerativedisease, are recurring themes throughout the book. We are all now part of the regeneration revolution."

With the explosion of information on autophagy in cancer, this is an opportune time to speed the efforts to translate our current knowledge about autophagy regulation into better understanding of its role in cancer. This book will cover the latest advances in this area from the basics, such as the molecular machinery for autophagy induction and regulation, up to the current areas of interest such as modulation of autophagy and drug discovery for cancer prevention and treatment. The text will include an explanation on how autophagy can function in both oncogenesis and tumor suppression and a description of its function in tumor development and tumor suppression through its roles in cell survival, cell death, cell growth as well as its influences on inflammation, immunity, DNA damage, oxidative stress, tumor microenvironment, etc. The remaining chapters will cover topics on autophagy and cancer therapy. These pages will serve as a description on how the pro-survival function of autophagy may help cancer cells resist chemotherapy and radiation treatment as well as how the pro-death functions of autophagy may enhance cell death in response to cancer therapy, and how to target autophagy for cancer prevention and therapy what to target and how to target it.

Biology of the Arterial Wall is intended as a general reference text concerned with the biology of the vascular cells and the blood vessel wall under physiological and pathological conditions. One of the major functions of the arteries is to maintain a continuous blood flow to the organs whatever the pressure conditions, thanks to the vasomotor tone of the smooth muscle cells. Great advances have been made over the last decade in the understanding of the endothelial cells as integrators and transducers of signals originating from the blood stream. The pluripotent control functions of the endothelial cells in the vessel wall are now well recognized. A review of endothelial functions and dysfunctions is presented. Cell biology and molecular genetic studies have now identified an array of molecules elaborated by endothelial cells and vascular smooth muscle cells and by the blood-borne elements which interact with artery cells, defending the artery against injury and modulating evolving abnormal processes. Molecules which induce or inhibit endothelial and/or smooth muscle cells are currently under great scrutiny. Angiogenesis, which plays a major role in tumor growth, but may also be beneficial as a healing process in muscle ischemia, is discussed. Apoptosis, or programmed cell death, has only recently been recognized as an essential process in blood vessel modeling and remodeling. An overview of apoptosis in the vascular system is presented. It is increasingly evident that the adjustments of the blood vessel wall are made in the presence of deforming disease processes such as hypertension and atherosclerosis. The second part of the book is concerned with the blood vessel wall in disease conditions. Several chapters review the role of the vessel and vascular cells in inflammation, and vascular remodeling during arterial hypertension and aging. One chapter is devoted to atherogenesis, atheroma and plaque instability, followed by the pathophysiology of post-angioplasty restenosis, which is a crucial issue in modern interventional cardiology.
