It is becoming increasingly clear that the brain has an important role in the control and integration of the responses to injury and infection. This is the first volume to look in depth at the way the brain responds to trauma and subsequently integrates and influences behavioral, metabolic, neurohumoral, cardiovascular, and immune functions. It is well established that some of these responses, such as fever and neuroendocrine changes are directly influenced by the central nervous system. These, and other more recent advances, provide new insights into this area and provide a basis for more effective understanding and clinical management of trauma patients. The authors, all international authorities in their fields, discuss established and recent data from experimental and clinical studies and consider the implications of these findings for the treatment of the trauma patient. This book will serve as an excellent reference for professionals who deal with trauma or who work in accident and emergency medicine, neuroscience, neuroimmunology and physiology.
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 and CD-ROM package integrates the use of STELLA software into the teaching of health, nutrition and physiology, and may be used on its own in nutrition and physiology courses, or can serve as a supplement to introduce the role that simulation modelling can play. The author presents key subjects ranging from the theory of metabolic control, through weight regulation to bone metabolism, and gives readers the tools to simulate these using the STELLA software. Topics include methods for simulation of gene expression, a multi-stage model of tumour development, theories of ageing, circadian rhythms and physiological time, as well as a model for managing weight loss and preventing obesity.
Since the epochal discovery of the radical and highly toxic gas nitric oxide (NO) as a signaling molecule, two other no less toxic gases - carbon monoxide (CO) and hydrogen sulfide (H2S) - have been found to also be involved in a plethora of physiological and pathophysiological functions. The gases termed gasotransmitters play an increasingly important role in understanding how signalling into and between cells is modulated and fine-tuned. The advent of gasotransmitters has profoundly changed our way of thinking about biosynthesis, liberation, storage and action mechanisms in cellular signaling. In recent years an impressive amount of new data, distributed throughout the existing literature, has been generated. For this book the editors have recruited distinguished colleagues in the field to summarize and review important biological, pharmacological and medical functions and their implications, as well as methods for the detection of gasotransmitters.
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.
Ischemie heart disease is still the most frequent cause of death in the western world. There have been significant achievements in diagnostic procedures as well as in the medical, invasive,and surgiealtreatment ofischemieheart disease inrecent years. A variety ofdrugs are availablefor the pharmacotherapyofischemieheart disease,par- ticularly nitrates, ss-blockers, and calcium-antagonists which are used as mono- therapy or in various combinations. However, the selection of patients for a certain treatment, as weIl as the optimization of an individual treatment are still largely empirical. On the other hand, the recent advances in experimental cardiology emphasize the extremely complex and dynamie scenario of ischemic heart disease, involving endothelial damage, coagulation processes, metabolie and morphologie derangements, coronary constrictor mechanisms, blood flow redistribution, arrhythmogenesis, contraetile dysfunction during ischemia and reperfusion, and finally lack or presence of pain perception. Therefore, it appears desirable to close the gap between experimental and clinical cardiology and, thus, to provide a pathophysiologieal basis for rational cliniealdecisions with respect to diagnostic and therapeutic procedures. The idea for this book arose during the preparation of a seminar series on experi- mental cardiology, when I found it diffieultto collect the pertinentinformation from textbooks of cardiology, physiology, pathology, and pharmacology, as well as from numerous review and original artieies on specifictopies. I am now very grateful that expert cliniealand experimental colleagues from around the world have joined me in the effort to provide a comprehensive textbook on the pathophysiology of myocar- dial ischemia and its rational pharmacotherapy.
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."
An essential component of inflammation is the migration of circulating leukocytes from blood into tissues. This process is characterized by a multistep paradigm of sequential cell adhesion and activation events that lead to the extravasation of specific leukocyte subsets to different tissues in health and disease. The first step of leukocyte extravasation, the rolling of leukocytes, is primarily mediated by the interactions of selectins and their ligands. It has recently become evident that fucosyltransferases are crucial for selectin ligand synthesis, inflammation, and skin homing. This book provides an in-depth overview of the mechanisms of leukocyte trafficking and of the molecular mechanisms of selectin/selectin ligand interactions and discusses options for pharmacological intervention to treat inflammatory diseases.
Unique features of the present work include: Only authorized English translation of the original Spanish text, adhering as much as possible to the letter, with correction of the obvious errors already predicted by Cajal in his Preface. Added facts appearing in the French version, with correction of old as well as new errors, the latter probably due to inaccuracies in translating into French some nuances of the Spanish language. Uniform of nomenclature according to contemporary scientific English. Annotations on Cajal s changing concepts over time, the elucidation of certain structures that do not have present day equivalents, and explanations of the many symbols appearing in illustrations but not mentioned in the corresponding original legends. Most illustrations are reproductions of Cajal s original art work, still extant at the Cajal Museum in Madrid, with cross references to figure numbers of the Spanish and French versions. Citations are given by author and year in the text, with an alphabetical list at the end of the volume, completed and corrected for accuracy against original publications. Taxonomy glossary of species appearing in the text, with present scientific names, and their colloquial English counterparts."
Speech sound production is one of the most complex human activities: it is also one of the least well understood. This is perhaps not altogether surprising as many of the complex neurological and physiological processes involved in the generation and execution of a speech utterance remain relatively inaccessible to direct investigation, and must be inferred from careful scrutiny of the output of the system -from details of the movements of the speech organs themselves and the acoustic consequences of such movements. Such investigation of the speech output have received considerable impetus during the last decade from major technological advancements in computer science and biological transducing, making it possible now to obtain large quantities of quantative data on many aspects of speech articulation and acoustics relatively easily. Keeping pace with these advancements in laboratory techniques have been developments in theoretical modelling of the speech production process. There are now a wide variety of different models available, reflecting the different disciplines involved -linguistics, speech science and technology, engineering and acoustics. The time seems ripe to attempt a synthesis of these different models and theories and thus provide a common forum for discussion of the complex problem of speech production. Such an activity would seem particularly timely also for those colleagues in speech technology seeking better, more accurate phonetic models as components in their speech synthesis and automatic speech recognition systems.
Cardiovascular disease is the leading cause of morbidity and premature death of modern era medicine. It is estimated that approximately 81 million people in the United States (US) currently have one or more of the many forms of cardiovascular disease, resulting in 1 in every 2.8 deaths, or 900,000 deaths per year. 40% of all deaths in Europe are a result of cardiovascular disease in people under the age of 75. Aneurysms form a significant portion of these cardiovascular related deaths and are defined as a permanent and irreversible localised dilation of a blood vessel greater than 50% of its normal diameter. Although aneurysms can form in any blood vessel, the more lethal aneurysms develop in the cranial arteries, and in the thoracic aorta and abdominal aorta. Frequently aneurysms are undetected and if left untreated may eventually expand until rupture with very high levels of morbidity and mortality. The biomechanics and mechanobiology of aneursymal diseases are not fully understood and this monograph aims to provide new insights into aneurysm aetiology and behavior based on the most recent biomechanics research related to this important topic. The contributors to this volume bring together a unique blend of expertise in experimental, computational and tissue biomechanics relating to aneurysm behavior and enable the reader to gain a fresh understanding of the key factors influencing aneurysm behavior and treatment. Biological risk factors such as tobacco smoking, sex, age, hypertension, family history and mechanobiological risk factors such as aneurysm geometry and shape as well as mechanical properties of the diseased tissues are considered in detail as are many of the diagnostic and treatment options.
The primary goal of this book is to survey issues pertaining to coronary venous retroperfusion, a potentially beneficial treatment of myocardial ischemia. Since attention will be focused on the myocardium, its normal or deranged antegrade perfusion will be discussed first, along with factors affecting blood supply to region ally ischemic tissue. After pointing to coronary reperfusion and its rapidly expand ing applications, the principle of coronary venous interventions will be discussed. Recent anatomic observations are presented to clarify features of the coronary venous sytems, some of which remain inadequately defined, yet play a crucial role in determining effectiveness of all retrograde methods. The remainder of the text concentrates on the development of retroperfusion sytems designed for retrograde treatment of myocardium jeopardized by deficient ante grade blood delivery, sec ondary to coronary artery obstruction. Retroinfusion of contrast is also considered as a potential diagnostic tool. The final chapter of the book reports on recent efforts aimed at a mathematical modeling of mechanisms and effects of coronary venous interventions."
Cardiac performance is regulated not only by cardiac muscle properties but also by several other factors, including those associated with the neurohumoral system and the mechanical characteristics of the peripheral circulation. New information con cerning these regulatory factors has furthered our understanding of the pathophysi ology of cardiac dysfunction. However, controversy remains, along with a need to integrate these multidisciplinary findings. It was with this in mind, together with my continuing interest in the response of the normal and diseased heart to variations in loading conditions, that the satellite symposium entitled "Interactions Between Car diac Function and Vascular Dynamics" was organized and dedicated to my mentor, Dr. T. Takishima. The symposium was held in Fukushima, Japan, in 1992 following the Tenth Inter national Conference of the Cardiovascular Systems Dynamics Society in Kobe, Japan, which was organized by the then president of the society, Dr. Masatsugu Hori. The Fukushima symposium and the Kobe conference were stimulating and informative. To commemorate these events, Dr. Hori, Dr. Janicki, and I decided to publish this book. It covers topics that were presented then as well as pertinent new material. As a result, the book includes not only updated reviews but also up-to-date findings that were not considered at the two scientific sessions. The high level attained in this book is due to the outstanding contributions from internationally renowned scientists. This final product of their efforts should prove to be a valuable source of information to the reader."
This comprehensive treatise on the reticuloendothelial system is a project jointly shared by individual members of the Reticuloendothelial (RE) Society and bio medical scientists in general who are interested in the intricate system of cells and molecular moieties derived from those cells which constitute the RES. It may now be more fashionable in some quarters to consider these cells as part of what is called the mononuclear phagocytic system or the lymphoreticular system. Nevertheless, because of historical developments and current interest in the subject by investigators from many diverse areas, it seems advantageous to present in one comprehensive treatise current information and knowledge con cerning basic aspects of the RES, such as morphology, biochemistry, phylogeny and ontogeny, physiology, and pharmacology as weIl as clinical areas including immunopathology, cancer, infectious diseases, allergy, and hypersensitivity. It is anticipated that by presenting information concerning these apparently heterogeneous topics under the unifying umbrella of the RES attention will be focused on the similarities as weIl as interactions among the cell types constitut ing the RES from the viewpoint of various disciplines. The treatise editors and their editorial board, consisting predominantly of the editors of individual vol umes, are extremely grateful for the enthusiastic cooperation and enormous task undertaken by members of the biomedical community in general and especially by members of the American as weIl as European and Japanese Reticuloendothe lial Societies."
Biological order in all living creatures is a fascinating phenomenon. Biochemical reactions and biophysical processes including enormous amount of various entities and structures are coordinated in space and time resulting in highly organized dynamic system with self control. The book consists of analysis of biophysical mechanism of long range interactions based on polar vibrations in microtubules and in actin filaments in cytoskeleton, spectral energy transfer in non-linear systems, excitation of a state far from the thermodynamic equilibrium in systems with energy supply, transition from incoherent to coherent vibration states, generation of endogenous electromagnetic field, information transfer between vibration systems, and interaction energy of vibration systems. The Frohlich vibration system is used."
Scientific progress with respect to the important role of various lipids in myocardial function and the dearrangements of lipid metabolism underlying ischaemic heart disease(s) has been con siderable in recent years. In 1986 alone, an overall number ofl 044 full papers covering the topics "Lipids-Heart-Heart Disease," have been published in a variety of biochemistry, physiology, pharmacology and cardiology journals (source: Index Medicus). They have broadened our in sight into the molecular basis of myocardial lipidology and the lipido-chemical basis of car diology in health and disease, and have narrowed the gap between promising pharmacological intervention in experimental animals and clinical treatment of patients suffering from an ischaemic heart. Furthermore, they illustrate the fundamental significance of the product of the union between basic and clinical science. The rapid development of knowledge in the "Lipids-Heart-Heart Disease" triad prompted us to organize the International Symposium on Lipid Metabolism in the Normoxic and lschaemic Heart, held in Rotterdam (The Netherlands) on September 22 and 23, 1986. This meeting was a coproject of the Department of Biochemistry I (Medical Faculty, Erasmus University Rotter dam) and the Department of Physiology (Medical Faculty, University of Limburg) and was held under the auspices of the GerritJan Mulder Foundation (named after a famous Rotterdam physi cian and chemist who lived from 1802-1880) whom we thank for their co-operation. The present volume is a compendium of invited papers and contributions selected from the posters presented during the symposium."
It is increasingly recognized that various transporter proteins are expressed throughout the body and determine absorption, tissue distribution, biliary and renal elimination of endogenous compounds and drugs and drug effects. This book will give an overview on the transporter families which are most important for drug therapy. Most chapters will focus on one transporter family highlighting tissue expression, substrates, inhibitors, knock-out mouse models and clinical studies.
The workshops that have been held over the past few years and the volumes published in their wake have proved highly successful and have prompted us to press on with our initial plans. Our basic aim was to tackle certain very important problems in respiratory rehabilitation and then discuss the various issues with people from all over the wodd engaged in the updating of experience and know ledge in this field. We therefore firmly believe that this ongoing effort is of fundamental importance. Hyperinflation, which is still a poody defined c1inical and physiopatho logical condition, is the focal point ofthis present study, which is aimed at discussing and weighing up the physiopathological mechanisms, c1inical consequences, and rehabilitation possibilities in a disease in which, until relatively recently, rehabilitation had seemed almost totally ineffective. The present contributions, however, show us how very important and versatile rehabilitation may be in its treatment. Perhaps, if we consider this branch of medicine as one which now no longer simply draws upon other sciences, but make an active contribution in its own right, we will have touched upon the most important aspect of this study. If I may, I would just like to add how very pleasing it is for me to acknow ledge how much this joint effort has contributed, in terms of true insights and above all VI results, to finding solutions to the problems addressed in reeent years.
The International Hypoxia Symposium convenes biannually to bring together international experts from many fields to explore the state of the art in normal and pathophysiological responses to hypoxia. Representatives from five continents and 32 countries joined together in February 2003 for four days in the dramatic mountains of Banff, Alberta. As editors of the Proceedings of the International Hypoxia Symposia, we strive to maintain a 26 six year tradition of presenting a stimulating blend of clinical and basic science papers focused on hypoxia. Topics covered in 2003 include hibernation and hypoxia, hypoxia and fetal development and new advances in high altitude pathophysiology, oxidative stress and membrane damage, hypoxic regulation of blood flow, heat shock proteins in hypoxia, and future directions in hypoxia research. In 2003 we also had the privilege ofhonoring John W. Severinghaus as a friend, colleague, mentor and inspiration to many in the field. Tom Hornbein's personal tribute to John Severinghaus is the first chapter in this volume, followed by an entertaining update of the history of the discovery of oxygen written by John Severinghaus.
This first volume in a projected series contains the proceedings of the first of the Keio University International Symposia for Life Sciences and Medicine under the sponsorship of the Keio University Medical Science Fund. As stated in the address by the President of Keio University at the opening of the 1996 symposium, the fund of Dr. Mitsunada Sakaguchi. The Keio was established by the generous donation University International Symposia for Life Sciences and Medicine constitute one of the core activities of the fund. The objective is to contribute to the international community by developing human resources, promoting scientific knowledge, and encouraging mutual exchange. Every year, the Executive Committee of the Interna tional Symposia for Life Sciences and Medicine selects the most interesting topics for the symposium from applications received in response to a call for papers to the Keio medical community. The publication of these proceedings is intended to publicize and distribute information arising from the lively discussions of the most exciting and current issues during the symposium. Weare grateful to Dr. Mitsunada Sakaguchi, who made the symposium possible, the members of the program committee, and the office staff whose support guaran teed the success of the symposium. Finally, we thank Springer-Verlag, Tokyo, for their assistance in publishing this work. Akimichi Kaneko, M. D. , Ph. D.
Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow. |
