Vaccination is one of the most efficient and cost effective methods of promoting human health and has been in clinical use for at least 200 years. Nevertheless, infectious diseases continue to constitute a constant threat to the well being of humanity. Common pathogens, once believed to be under control, acquire increased virulence and resistance to drugs, while exotic microorganisms emerged from hidden reservoirs to cause yet incurable diseases in humans. These changes, together with epidemic outbreaks related to political and socio-economic instabilities, increase the needs for the development of new, advanced vaccines. In this volume, devoted to the proceedings of the 39th OHOLO Conferenc...
Development and Implications of Antimicrobial Resistance One of the most ominous trends in the field of antimicrobial chemotherapy over the past decade has been the increasing pace of development of antimicrobial resistance among microbial pathogens. The hypothesis that man can discover a magic bullet to always cure a particular infection has proved false. Physicians are now seeing and treating patients for which there are few therapeutic alternatives, and in some cases, none at all. Until recently there was little concern that physicians might be losing the war in our ability to compete with the evolving resistance patterns of microbial pathogens. Now the general public is very aware of the...
The three years since our last conference in San Francisco have again seen a dramatic expansion of the number of antivirals either licensed or in the late stages of clinical trials. d4T is now licensed for HIV infection, famciclovir and the oral pro-drug of acyclovir, valacyclovir, are now licensed for VZV infections in some countries. Moreover. oral ganciclovir, cidofovir, and sorivudine are not far behind. Clinical trials with the second-site reverse transcriptase inhibitors and the protease inhibitors for HlV infection are proceeding rapidly and on a broad scale, and the preliminary results would suggest that several of these classes of drugs will be licensed as well. Despite this optimis...
Contents: Current health care scenes. Introduction of medical developments, choices of priorities for the community served and changes in configuration of services.

Appraisal of quality and effectiveness, including the handling of complaints.
Scientific advances over the past two decades have afforded unprecedented oppor tunities to understand the structure and function of receptors, receptor-ligand interactions, and receptor signaling. The extent ofprogress in this area is underscored by the recent Nobel Prize for Medicine and Physiology to Alfred Gilman and Martin Rodbell, both of whose work in understanding receptorlG-protein interactions has redefined the way in which we think of how hormones and neurochemicals exert their activity on cellular function. This book is replete with examples of current research approaches to help us better understand the cellular roles in which the renin-angiotensin system and the angiotensin rec...
Wide and fascinating is the field of research on tryptophan, a most versatile amino acid, transformed, as it is, in our organism into many biologically active substances. This volume contains the proceedings of the Eighth International Meeting on Tryptophan Research, held at the University of Padova, Padova, Italy, from June 25 to 29 1995, under the auspices of the University of Padova, National Research Council, Italian Chemical Society-Division of Pharmaceutical Sciences, Region ofthe Veneto and City of Padova. The meeting was held in Padova to commemorate Prof. Luigi Musajo twenty years after his death and the editors dedicate this book to him in recognition of his pioneering work in tryptophan metabolism. Prof. Osamu Hayaishi delivered the Musajo Memorial Award Lecture: Tryptophan oxygenase. and sleep. Figure I shows the ISTRY President Prof. Simon N. Young presenting the Musajo Memorial Medal to Prof. Hayaishi during the Opening Ceremony. Two hundred scientists from twenty two countries participated in the meeting. These proceedings contain 121 papers encompassing a variety of topics and disciplines.
From beach encounters, aquaculture perils, and processed-food poisoning to snake bites and biological warfare, natural toxins seem never to be far from the public's sight. A better understanding of toxins in terms of their origin, structure, structure-function relation ships, mechanism of action, and detection and diagnosis is of utmost importance to human and animal food safety, nutrition, and health. In addition, it is now clear that many of the toxins can be used as scientific tools to explore the molecular mechanism of several biological processes, be it a mechanism involved in the function of membrane channels, exocytosis, or cytotoxicity. Several of the natural toxins have also been ap...
