In his treatment of activity measurement in the fields of medicine and psychology, Tryon gives us a book that clearly accomplishes the three purposes set out in its preface. The reader is definitely encouraged to wrestle with the concepts ofbehavior and activity in terms of "dynamic physical quantities." Moreover, the reader cannot help but become familiarized with the technology available for performing activity measurements. Motivation to use some of this technology is enhanced by the very extensive summary of other people's uses of it provided throughout the book. Readers may find the book...

The idea for this book came from discussions among participants in a symposium on biotechnical applications at the "Pacifichem 89" meeting in Honolulu. It was the majority opinion of this group that a volume dedicated to biotechnical and biomedical applications of PEG chemistry would enhance research and development in this area. Though the book was conceived at the Honolulu meeting, it is not a proceedings of this symposium. Several groups who did not participate in this meeting are repre- sented in the book, and the book incorporates much work done after the meeting. The book does not...

The formation of drug policy is a complex phenomena influenced by a multi tude of sources. Among others, these influences include historical factors, contemporary public opinion regarding the nature and magnitude of drug use and abuse, the portrayal of illicit drugs and drug use in the media, and lobbying efforts by special interest groups (e. g., The Drug Policy Foundation), including government agencies (e. g., the Justice Department and law enforcement). An additional source of influence are the activities of specialists directly engaged in studying drug use and treating drug dependence....

As we approach the end of this millennium, enteric diseases remain impor tant public health problems. In many parts of the world, sanitary measures have advanced little over the last century, although some of the governments in those areas are striving to improve facilities for sanitation and to educate their people in proper handling of food, water, sewage, and other modes of transmission of pathogenic microbes. Even in highly developed countries, outbreaks of diarrheal diseases occur today. Globally, the annual morbidity from enteric infections is estimated at several billion and deaths at...

Staphylococcus aureus is now acknowledged as being the most important bacterial pathogen of humans. It usually produces localized disease but can be rapidly invasive, spreading through the tissues, invading bone, and seeding the bloodstream to produce a fulminant picture of septic shock, disseminated intravascular coagulation, and rapid death. Moreover, most strains of staph infections are becoming resistant to most antibiotics, thus posing a significant problem for hospitals and health care facilities. This book, a volume in the Infectious Agents and Pathogenesis...

The discovery and concept that Helicobacter pylori is associated with gastric disease including gastric cancer which is one of the most common and frequently lethal forms of malignancy, heralded a new and rapidly expanding field recognizing the emergence of many new pathogens and disease syndromes in clinical medicine, as well as basic infectious disease research. There is now an extensive and widely known literature of how H. pylori is involved in a wide variety of disease syn dromes. As summarized in the introductory chapter of this volume, many major advances have been made in diagnosis,...

The use of recreational drugs of abuse by large numbers of individuals in this country and abroad has aroused serious concerns about the consequences of this activity. For example, it is recognized that marijuana is currently widely used as a recreational drug in the United States as well as other countries. Similarly, abuse of cocaine, especially crack cocaine, is considered to be an epidemic. The war on drugs by the US Government was directly aimed at the illicit use of cocaine, marijuana, and opiates as well as other drugs of abuse. Furthermore, alcohol is also considered a major problem...

An AIDS vaccine is still elusive and HIV treatment continues to develop multidrug resistance at alarming rates. Because of the similarities between HIV and immune deficiency infections in a variety of animals, it is only natural that scientists use these animals as models to study pathogenesis, treatment, vaccine development and many other aspects of HIV.

Part of the series Infectious Agents and Pathogenesis, this volume reviews the immune deficiency virus in a variety of hosts. Pathogenesis, vaccine and drug development, epidemiology, and the natural history of the monkey,...
