The need to continually discover new agents for the control or treatment of invertebrate pests and pathogens is undeniable. Agriculture, both animal and plant, succeeds only to the extent that arthropod and helminth consumers, vectors and pathogens can be kept at bay. Humans and their companion animals are also plagued by invertebrate parasites. The deployment of chemical agents for these purposes inevitably elicits the selection of resistant populations of the targets of control, necessitating a regular introduction of new kinds of molecules. Experience in other areas of chemotherapy has shown that a thorough understanding of the biology of disease is an essential platform upon which to build a discovery program. Unfortunately, investment of research resources into understanding the basic physiology of invertebrates as a strategy to illuminate new molecular targets for pesticide and parasiticide discovery has been scarce, and the pace of introduction of new molecules for these indications has been slowed as a result. An exciting and so far unexploited area to explore in this regard is invertebrate neuropeptide physiology. This book was assembled to focus attention on this promising field by compiling a comprehensive review of recent research on neuropeptides in arthropods and helminths, with contributions from many of the leading laboratories working on these systems.
Signal Transduction in Cardiovascular System Health and Disease highlights the major contributions of different signaling systems in modulating normal cardiovascular functions and how a perturbation in these signaling events leads to abnormal cell functions and cardiovascular disorders. This title is volume 3 in the new Springer series, Advances in Biochemistry in Health and Disease.
This book is designed to provide a comprehensive insight into current perspectives and challenges in adipose tissue biology. In Adipose Tissue Biology, scientists and clinicians discuss adipocyte precursors, differentiation and growth, brown and white adipose tissue, gender, inflammation, dietary and genetic determinants of fat mass, together with evolutionary and developmental aspects of adiposity.
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.
The aim of this book is to focus on the important relationships between the heart and the brain in health and disease. The brain and nervous system may cause or influence heart disease, e. g. , by causing arrhythmias or modi- fying the response to ischemia. Disorders of the heart and circulation may cause brain damage, e. g. , by releasing emboli resulting in cerebral infarc- tion. Furthermore, both the brain and the heart are frequently targets of the same disease process. The heart and brain have electrophysiologically active cells, which may respond in similar ways to diseases and various interventions. Finally, many drugs affect both the brain and the heart, and drugs used for heart diseases usually have side effects on the brain and vice versa. With today's increasing subspecialization in medicine, we feel the time has come to present a book that integrates basic and clinical aspects of cardiology, neurology, cardiovascular surgery, and neurosurgery. We hope this cross fertilization will broaden horizons and advance both understand- ing and practice. This book is based on a symposium held at the University of TromS!/l, Norway, 24-27 June 1987, organized by Ilmar A. Sulg, Knut Rasmussen, Svein Ivar Mellgren, Dag S!/lrlie, and Helge Refsum of the Departments of Clinical Neurophysiology, Medicine, Neurology, Surgery, and Physiology, respectively. Weare grateful to the distinguished group of contributors for not only outlining their pioneering studies, but also describing their recent work and indicating important possibilities for the future.
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."
Translational medicine underpins vascular medicine. It is fundamental to understanding how we treat patients with vascular disease and more importantly, how to prevent it. It is the rationale for drug design and production. Vascular medicine and translational medicine will take over and become the main reason for referring patients to hospital. Therefore, hospital-based clinicians working with basic scientists need to know about translational medicine, which educates and informs them about vascular medicine and how management should be based. This book is a primer for translational vascular medicine and discusses the evolving and exciting areas of basic science applied to vascular medicine. The book is based on the third vascular biology conference held at The Royal College of Physicians in 2008. It provides a large amount of new basic and clinical information and the contributors are world leaders.
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.
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.

Designed for clinicians to guide and improve clinical treatment and diagnosis of patients with hypoxia mediated pulmonary vascular disease and right heart failure.
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.
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.
Many unexplored complex cellular and organismal adaptations occur in response to the stress of alcohol exposure, and its contribution to the development of chronic diseases, such as osteoporosis, heart disease and diabetes, is particularly relevant today, given the increased incidence of these diseases in our aging population. In Alcohol: Methods and Protocols, the pleiotropic effects of ethanol in animal and cell culture models are rigorously examined through a collection of detailed procedures written by experts in the field. Sections present clearly defined models of ethanol exposure, recent advances in the development of specific methodologies to mimic the impact of ethanol metabolism in cultured cells, and methodologies to investigate a variety of cells and tissues that are known to be disrupted by ethanol, amongst other topics.
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.

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.
Muscarinic acetylcholine receptors have played a key role in the advancement of knowledge of pharmacology and neurotransmission since the inception of studies in these fields, and the effects of naturally occurring drugs acting on muscarinic receptors were known and exploited for both therapeutic and non-therapeutic purposes for hundreds of years before the existence of the receptors themselves was recognized. This volume presents a broad yet detailed review of current knowledge of muscarinic receptors that will be valuable both to long-time muscarinic investigators and to those new to the field. It describes the detailed insights that have been obtained on the structure, function, and cell biology of muscarinic receptors. This volume also describes physiological analyses of muscarinic receptors and their roles in regulating the function of the brain and of a variety of peripheral tissues. This volume shows how the study of muscarinic receptors continues to provide new and surprising insights not just to the cholinergic system but to the broad areas of neurobiology, cell biology, pharmacology, and therapeutics.
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.
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."
In this second special issue on signal transduction leading specialists in their fields again present overviews of topics related to the highly topicalsubject of signal transduction. The first contribution, by Keppler, deals with the biosynthesis, transport, inactivation, and analysis of leukotrienes. Mohr et al. present an excellent overview of the biology of the peptide hormone oxytocin and its role in signal transduction.The review by Holzer describes the significance of peptinergic sensory neurons in the control of vascular functions. In the contribution by Wolf etal the molecular biology of the Y chromosome is discussed. |
