The Third Annual Symposium on Health Sciences attracted over 400 scientists from 15 countries. It was held at the National Academy of Sciences in Washington, D.C. The theme of this meeting was "Thymic Hormones and Lymphokines: Basic Chem istry and Clinical Applications." The meeting emphasized the state of the art with regard to chemistry, mech anism of action, and clinical applications of thymic hormones and lymphokines. In addition to the five sessions, the chairmen of each session were asked to prepare a synthesis and overview of each of the sessions. Some of the chairmen used this time to summarize the new material presented while others addressed important areas of conflict and terminology. The chairmen of the plenary sessions prepared short summary papers which have been incorporated into this volume at the end of each major section. We also invited several of the scientists who took part in the poster presentations to submit short papers. In addition to the scientific sessions, there were two awards and lectures. One, the Abraham White Distinguished Science Award, was given to Dr. Robert C. Gallo, who gave the keynote lecture. He was recognized for his pioneering research and scientific contributions to our understanding of the regulation of hematopoietic cell differentiation and the role of viruses in the development of human leukemias.
The Janeway's Immunobiology CD-ROM, Immunobiology Interactive, is included with each book, and can be purchased separately. It contains animations and videos with voiceover narration, as well as the figures from the text for presentation purposes.
Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.
First published in 1990. This important new text covers a wide area of thymology in both the theoretical and practical aspects. In view of current information, a crucial role of endocrine thymus is presented in the creation, maintenance, and senescence of neuro-endocrine-immune homeostasis. In particular, mechanisms are described (which are basically responsible for the T cell maturation and selection) for the hierarchic organization of the immune system and its thymic dependent immune competence in terms of tolerance and immunity. A detailed presentation of the structure and biological properties of a number of well-defined thymic hormones is included. Their clinical applications and results obtained in inherited or acquired immunodeficiencies and in neoplasmic diseases are also reviewed on the grounds of numerous representative clinical trials. A perspective and potential scope of immunorestorative therapy and prevention with thymic hormones and other thymomimetic drugs are outlined. Researchers, practitioners, and students will find this book to be a useful and essential source of information.
The thymus is a gland that over the last two centuries has generated great awareness not only from the anatomical perspective but also for the physiological and pat- logical roles it plays in many disease processes. Prior to the early studies on its th anatomy and physiology in the 18 century, the thymus was believed to perform - usual and curious functions such as purification of the nervous system, providing a protective cushion for the vasculature of the superior mediastinum, fetal nouri- ment, or more spiritual roles such as being the seat of the soul, among others. D- th ing the 19 century important anatomical/physiological studies took place focusing on the role of the thymus in pathological conditions. However, it was not until the th middle of the 19 century that a more comprehensive analysis of the role of the thymic gland and its role in pathogenesis began to emerge. Currently, while the knowledge gained on the diverse aspects of the thymic gland has furthered our understanding of its role in a gamut of processes, more knowledge is still being sought, and by no means is a full understanding of the gland’s physi- ogy and pathology complete. Different aspects, including its purported endocrine function, its association with other autoimmune diseases like multiple sclerosis, rheumatoid arthritis, and lupus erythematosus, among others, are under evaluation and research.
Tamoxifen has persisted as a widely accepted and administered drug for almost 25 years. Following the many scientific papers and books on the subject, it has remained a very intriguing substance. This, perhaps, is the reason for another monograph on Tamoxifen. It is regrettably true that overviews, even when up to date after exhaustive research - the shibboleth of our cultures -, rapidly lose relevance with the passage of time. Scientists can sometimes be pictured as deep sea divers, who plunge into the unknown in search of a hitherto unknown world. Their descent is exciting, but eventually they must come up for air and integrate their experiences with others who also had to resurface. This book intends to collect and, where possible, to collate recent, but sometimes seemingly unrelated information. To quote Stephane Mallarme: "Everything in the world exists to end up in a book". Even if this is a tad cynical, it might not be far from the truth. If a little knowledge is a dangerous commodity, one can also add - tongue in cheek - that a vast amount of knowledge can be truly hazardous. It is likely that what might seem as entangled data is confusing, especially for those satisfied with the comfortable interpretation of Tamoxifen as an antiestrogen which has long been found insufficient. The complexity of its mechanisms and effects defies simple explanations and may even seem capricious, but only because of our ignorance.
The Immunology Guidebook provides an easily accessible text-reference to the more up-to-date and difficult concepts in the complex science of immunology. It aims to demystify basic concepts and specialised molecular and cellular interactions. Its 18 chapters offer a logical and sequential presentation where much of the data is displayed in carefully designed tables. This book is intended for immunology students, researchers, practitioners and basic biomedical scientists. - Tables provide a quick reference to 'difficult to find' immunology data - A distillate of the latest information on immunogenetics of the human MHC associated with tissue transplantation - Information boxes featurw related web resources
The Fifth International Lymphokine Workshop was convened in Clearwater Beach, Florida, January 11-15, 1987. The theme chosen for the meeting was 'The Molecular Basis of Lymphokine Action," which reflected the opinion of the organizers as to how far the field had moved since the first Lymphokine Workshop only eleven years ago. As was evident at the last Lymphokine Workshop held in 1985, the contribution of molecular biology, particularly in the cloning of lymphokine genes, continues to play an important role in clarifying the structure of lymphokines, providing recombinant (read "pure") proteins for biological studies, and suggesting directions for studies of the molecular basis of lymphokine activity. The most recent lymphokines to yield to molecular cloning meth odology were the B-cell growth and differentiation factors, in partic ular BSF-1 or, as it is sometimes termed, interleukin 4. One of the surprises from this research is the broad spectrum of activities that can be attributed to this molecule, aside from its effects on B-cells, thus perhaps justifying its being called an interleukin. The interleukin 2 symposium demonstrated that even in a well-established research area, controversy and excitement can continue, when evidence was presented by several investigators indicating the presence of a second "converter" protein that changes the affinity of the now classical Tac antigen from a low to a high affinity IL-2 receptor.
