I was pleased and at the same time filled with some misgivings when Professors Alberto Giotti end Ryan Huxtable asked me to introduce this book. The book is the outcome of the Symposium held in Firenze-San Miniato (PI), October 6-9, 1986. The symposium was entitled "Sulfur Amino Acids, Peptides and Related Compounds" and was the 7th international symposium on taurine ssnd assooiated substances. It is always difficult to introduce, with the right brevity end emphasis, a topic which has been studied in depth by numerous experte. Nevertheless, I shall do my best to give a historical perspeotive of the subjects of the meeting which I consider to be very important for the frontiers of researoh on taurine. ~he following topios have also beoome coherent areas of study during the development of researoh on taurine: metabolism, nutrition, neurochemistry, cardiovasoular regulation. Although taurine was isolated in 1821 by ~iedman and Gmel1n, its only biochemioal role known at the time was the synthesis of bile saIte in mammalian tissue. There has been an inoreasing interest in the biologioal action of taurine from metabolio aspects to other biologioal aspects (nutrition, development, eto.).In 1975 it was first demonstrated that taurine deprivation produoed retinal degeneration in cats; more reoent studies showed that a taurine-free diet or the administration of taurine transport inhibitors caused retinal degeneration in other mammlas. More reoent studies have pointed out the role of taurine in development, and the first part of this book is dedicated to these topios.

During the past three decades, the sugar moiety of complex carbohydrates has been found to be involved in important interactions of immunological specificity of antigens and to participate in a variety of cellular functions. The long polysaccharide side chains of the lipopolysaccharides on the outer membrane of Gram negative organisms provide surface antigens for differential serodiagnosis. Bacterial surface lectins are important in mediating the attachment of bacteria to host cells in the of infectious diseases. The carbohydrate pathogenesis moieties of cell surface glycoconjugates (glycoproteins and glycolipids) of mammals are the sites for intercellular recognition and for the regulatory molecular interactions such as interaction of complex carbohydrate with hormones or hepatic lectins. The carbohydrate side chains of many complex carbohydrates play essential roles as antigenic determinants b of human blood group ABH, Lea, Le , I, and i activities, as the Forssman specific determinant, and as tumor associated antigenic determinants. Prompted by these and other advances in the field, a Symposium on Molecular Immunology of Complex Carbohydrates was organized as a satellite meeting of the 8th International Glycoconjugate Conference held on September 8- 13, 1985, in Houston, Texas, U. S . A. Many eminent scientists contributed their knowledge at this meeting. The lecture and poster materials of the symposium are contained in this proceeding book, which is divided into four Sections and one Appendix. Section I is entitled Antibody Specificity, Epitope, and Lectinology. Dr. Elvin A.

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.

A variety of processing methods are used to make foods edible; to pennit storage; to alter texture and flavor; to sterilize and pasteurize food; and to destroy microorganisms and other toxins. These methods include baking, broiling, cooking, freezing, frying, and roasting. Many such efforts have both beneficial and harmful effects. It is a paradox of nature that the processing of foods can improve nutrition, quality, safety, and taste, and yet occasionally lead to the formation of anti-nutritional and toxic compounds. These multifaceted consequences of food processing arise from molecular interactions among nutrients with each other and with other food ingredients. Since beneficial and adverse effects of food processing are of increasing importance to food science, nutrition, and human health, and since many of the compounds formed have been shown to be potent carcinogens and growth inhibitors in animals, I organized a symposium broadly concerned with the nutritional and toxicological consequences of food processing. The symposium was sponsored by the American Institute of Nutrition (AIN) -Federation of American Societies for Experimental Biology (FASEB) for its annual meeting in Washington, D.C., April 1-5, 1990. Invited speakers were asked to develop at least one of the following topics: 1. Nutrient-nonnutrient interactions between amino acids, proteins, carbohydrates, lipids, minerals, vitamins, tannins, fiber, natural toxicants, etc. 2. Effects of radiation. 3. Thermally induced formation of dietary mutagens, antimutagens, carcinogens, anticarcinogens, antioxidants, and growth inhibitors. 4. Effects of pH on nutritional value and safety.

We are pleased to present our readers the proceedings of the International symposium on "New Aspects of Human Polymorpho- nuclear Leukocytes" which was held in Freiburg im Breisgau, FRG, from October 26-28th, 1989. The meeting provided an unique framework for close interaction between scientists from various disciplines, including bioche- mistry, biology, physiology, pathology, clinical chemistry, hematology, gynecology, surgery, intensive care medicine, nephrology, rheumatology, and infectious diseases. We would like to express our gratitude and appreciation for all those who have stimulated, encouraged, and supported us to hold the symposium in Freiburg. This endeavor could not have been possible without the generous financial support of Asid- Bonz (Boblingen), Bayer AG (Leverkusen), Bayropharm GmbH (Koln), Baxter (Munchen), Ciba-Geigy (Wehr/Baden), Cilag GmbH (Sulzbach), Fresenius AG (Oberursel), Gambro (Martinsried), Gry-Pharma GmbH (Kirchzarten), Hoechst AG (Frankfurt), Hospal (Nurnberg), Knoll AG (Ludwigshafen), Lederle-Cyanamid (Wolfratshausen) , E. Merck (Darmstadt), MSD Sharp and Dohme GmbH (Munchen), Pfizer GmbH (Karlsruhe), and Kabi/Pfrimmer (Erlangen).We are indebted to Mrs. I.

In the past 15 years much evidence has accumulated which indicates the paramount importance of sensory nerves in reg ulating functions of the gastrointestinal tract. In parallel, the attention of researchers in this field has been increas ingly attracted to the role played by neuropeptides in the normal and diseased gut. Basic research on the peculiar properties of capsaicin, the pungent ingredient from plants of the genus Capsicum, has allowed the gap between these two areas of research to be bridged. Sincethen, the study of gut afferents and neuropeptides has become more and more interconnected and recognized as a major avenue to understand ing the pathophysiology of various human diseases. It is widely recognized that a certain subset of primary afferents synthesize, store and release neuropeptides (such as tachykin nins and calcitonin gene-related peptide) from their central and peripheral endings, the latter being widely distributed in the alimentary canal and related organs (liver, pancreas). The First International Meeting on Sensory Nerves and Neuropeptides in Gastroenterology, held in Florence from December 4-5, 1989, sponsored and organized by Fondazione Internazionale Menarini, aimed to focus the current status of research in this field. The contributions presented at the meeting and in this book delineate a suggestive scenario in which sensory nerves of the gut, and the multiple messages they carry through the release of neuropeptides, are to be considered as a major target for the development of new drugs potentially useful in a number of diseases of the gastro intestinal tract.

This book was developed from the papers presented at a symposium on "Water Relationships in Foods," which was held from April 10-14, 1989 at the 197th National Meeting of the American Chemical Society in Dallas, Texas, under the auspices of the Agricultural and Food Chemistry Division of ACS. The editors of this book organized the symposium to bring tagether an es teemed group of internationally respected experts, currently active in the field of water relationships in foods, to discuss recent advances in the 1980's and future trends for the 1990's. It was the hope of all these con tributors that this ACS symposium would become a memorable keystone above the foundation underlying the field of "water in foods. " This strong foundation has been constructed in large part from earlier technical conferences and books such as the four milestone International Symposia on the Properties of Water (ISOPOW I-IV), the recent IFT BasicSymposium on "Water Activity" and Penang meeting on Food Preservation by Maisture Control, as well as the key fundamental contributions from the classic 1980 ACS Symposium Series #127 on Water in Polymers, and from Felix Franks' famous seven-volume Comprehensive Treatise on Water plus five subsequent volumes of the ongoing Water Science Reviews. The objective of the 1989 ACS symposiumwas to build on this foun dation by emphasizing the most recent and maj or advanc.

These two volumes record the scientific and clinical work presented at the VIIth International and 3rd European joint symposium on purine and pyrimidine metabolism in man held at the Bournemouth International Conference Centre, Bournemouth, UK, from 30th June to 5th July 1991. The series of international meetings at three yearly intervals have previously been held initially in 1973 in Israel, then Austria, Spain, the Netherlands, USA and Japan. The European society for the Study of Purine and Pyrimidine Metabolism in Man (ESSPPM) which has its own executive and some finance first met in Switzerland in 1987, then in Germany in 1989. The steady evolution of the science in this series of meetings is intellectually satisfying; the subsequent clinical progress is emotionally and economically reassuring. As befits the position of purines and pyrimidines at the centre of biochemistry, there has been steady scientific development into molecular genetics and now onto developmental controls and biochemical pharmacology. The complexities of the immune system are being unravelled but an understanding of the human brain largely eludes us. Laboratory based scientists now predominate over those who work as clinical specialists in vii rheumatology, immunology, oncology and paediatrics. However, there continue to be major clinical objectives since large sections are concerned with major causes of death like ATP depletion, cancer and now AIDS; the laboratory work is providing clinical solutions.

The Third International Symposium on Excitation-Contraction Coupling in Skeletal, Cardiac, and Smooth Muscle, organized by George Frank, C. Paul Bianchi, and Henk E. DJ. ter Keurs, was held in Banff Centre, Banff, Alberta, Canada during June 26 to June 30, 1991. The theme of these symposia has been to recognize the similarities and dissimilarities of excitation-contraction coupling in skeletal, cardiac, and smooth muscle. Cross fertilization of concepts of excitation-contraction coupling in these three types of muscle has occurred since the early studies in the late fifties and early sixties on skeletal muscle. Investigators in each field meet only at specialized symposia which exclude investigators in the other fields. The purpose of the symposia has been to bring together international investigators studying excitation-contraction coupling in skeletal, cardiac, and smooth muscle so that we may learn from each other and hence provide a more global concept of excitation-contraction. The Third International Symposia has accomplished its objective as we recognize that calcium channels of the sarcolemma and the sarcoplasmic reticulum play key essential roles in excitation-contraction coupling in all three types of muscles. In skeletal muscle the recognition that E-C coupling consists of two parallel mechanisms, one dependent upon a dihydropyridine voltage-sensitive sensors coupled to calcium release from the terminal cisternae via the ryanodine sensitive channel in the foot structure of the triad.

• . . . . At last the doctor will be freed from the tedious interpretation of screens and photographs. Instead, he will examine and scan through his patient directly. Wearing optical-shutter spectacles and aiming a pulsed laser torch, he will be able to peer at the beating heart, study the movement of a joint or the flexing of a muscle, press on suspect areas to see how the organs beneath respond, check that pills have been correctly swallowed or that an implant is savely in place, and so on. A patient wearing white cotton or nylon clothes that scatter but hardly absorb light, may not even have to undress . . . . •. David Jones, Nature (1990) 348:290 Optical imaging of the brain is a rapidly growing field of heterogenous techniques that has attracted considerable interest recently due to a number of theoretical advantages in comparison with other brain imaging modalities: it uses non ionizing radiation, offers high spatial and temporal resolution, and supplies new types of metabolic and functional information. From a practical standpoint it is important that bedside examinations seem feasible and that the implementations will be considerably less expensive compared with competing techniques. In October 1991, a symposium was held at the Eibsee near Garmisch, Germany to bring together the leading scientists in this new field.
