This report from the Committee on Military Nutrition Research reviews the history of caffeine usage, the metabolism of caffeine, and its physiological effects. The effects of caffeine on physical performance, cognitive function and alertness, and alleviation of sleep deprivation impairments are discussed in light of recent scientific literature. The impact of caffeine consumption on various aspects of health, including cardiovascular disease, reproduction, bone mineral density, and fluid homeostasis are reviewed. The behavioral effects of caffeine are also discussed, including the effect of caffeine on reaction to stress, withdrawal effects, and detrimental effects of high intakes. The amounts of caffeine found to enhance vigilance and reaction time consistently are reviewed and recommendations are made with respect to amounts of caffeine appropriate for maintaining alertness of military personnel during field operations. Recommendations are also provided on the need for appropriate labeling of caffeine-containing supplements, and education of military personnel on the use of these supplements. A brief review of some alternatives to caffeine is also provided.

In their classic paper in 1929, Drury and Szent-Gyorgyi described a number of the important cardiovascular actions of adenosine. Another thirty years were to pass before the possible physiological role of adenosine in coronary vasodilation was studied by Berne and others. Since then, there has been a tremendous increase in research into the actions of adenosine. Workers from many disciplines have employed a wide variety of techniques, since adenosine is a product of and a substrate for a number of metabolic pathways, is transported into cells, and acts at discrete receptor sites to modulate the activity of adenylate cyclase and to produce important actions on many cells and tissues including platelets, adipo cytes, heart, blood vessels, and other smooth muscles. International symposia on the actions of adenosine were held in 1978, 1981, and 1982, and the proceedings of these symposia have been published (Baer and Drummond, 1979; Daly et at., 1983; Berne et at., 1983). Since it is not the primary purpose of the present volume to review our current understanding of the nu merous actions of adenosine, these volumes should be consulted for such details. Rather, the present volume has been planned to provide both graduate students and investigators in pharmacology and related disciplines with a summary of some of the methods now available for the study of the actions of adenosine and, in particular, to highlight their possible uses and limitations.

In the past two decades a number of studies have shown that abnormalities in the function and structure of coronary microcirculation can be detected in several cardiovascular diseases. On the basis of the clinical setting in which it occurs, coronary microvascular dysfunction (CMD) can be classified into four types: CMD in the absence of any other cardiac disease; CMD in myocardial diseases; CMD in obstructive epicardial coronary artery disease; and iatrogenic CMD. In some instances CMD represents an epiphenomenon, whereas in others it represents an important marker of risk or may contribute to the pathogenesis of myocardial ischemia, thus becoming a possible therapeutic target. This book provides an update on coronary physiology and a systematic assessment of microvascular abnormalities in cardiovascular diseases, in the hope that it will assist clinicians in prevention, detection and management of CMD in their everyday activity.

This book is the first definitive overview on adenosine receptor antagonists and their application to the treatment of Parkinson's Disease. The effect of these novel non-dopamine drugs on vitro and in vivo systems clearly shows their potential for the treatment of this debilitating disease. This book covers how the Parkinson's disease antagonist drug, A2A, has been researched, developed, and tested. It is an essential book for researchers interested in the basal ganglia, purine biology, and Parkinson's Disease. Discusses the discovery and development of a novel non-dopaminomimetic agent for Parkinson's disease Provides the first definitive overview of adenosine antagonists and their role in the treatment of Parkinson's disease Presents a new mechanism of action of adenosine A2A receptor antagonists in motor function Proposes a hypothesis of adenosine A2A receptor function in the striatum Comprehensive overview of adenosine, its receptor subtypes, their antagonists/agonists from biochemistry, molecular biology, medicinal chemistry, physiology, pharmacology, and neurochemistry viewpoints

The activities of the Food and Nutrition Board's Committee on Military Nutrition Research (CMNR, the committee) have been supported since 1994 by grant DAMD17-94-J-4046 from the U.S. Army Medical Research and Materiel Command (USAMRMC). This report fulfills the final reporting requirement of the grant, and presents a summary of activities for the grant period from December 1, 1994 through May 31, 1999. During this grant period, the CMNR has met from three to six times each year in response to issues that are brought to the committee through the Military Nutrition and Biochemistry Division of the U.S. Army Research Institute of Environmental Medicine at Natick, Massachusetts, and the Military Operational Medicine Program of USAMRMC at Fort Detrick, Maryland. The CMNR has submitted five workshop reports (plus two preliminary reports), including one that is a joint project with the Subcommittee on Body Composition, Nutrition, and Health of Military Women; three letter reports, and one brief report, all with recommendations, to the Commander, U.S. Army Medical Research and Materiel Command, since September 1995 and has a brief report currently in preparation. These reports are summarized in the following activity report with synopses of additional topics for which reports were deferred pending completion of military research in progress. This activity report includes as appendixes the conclusions and recommendations from the nine reports and has been prepared in a fashion to allow rapid access to committee recommendations on the topics covered over the time period.

Cardiologists must answer three important questions when evaluating and treating patients with a coronary artery stenosis. As a physiologist: "What is the effect of this stenosis on coronary blood flow and myocardial function?"; as a clinician: " Is this lesion responsible for the patient's symptoms?"; and finally as an interventionalist: "Will revascularization of this artery improve the patient?" Fundamentally, the answer to these questions can be given to a large extent by measuring coronary pressure. That is the rationale of writing this book. 1. 1 Historical overview. Andreas Gruentzig and most interventional cardiologists in the early days of PTCA, had the intuitive feeling that pressure measurements could help to establish the severity of a coronary stenosis and to monitor the progress and result of a coronary intervention. At that time, measuring coronary pressure by the balloon catheter was part of a standard procedure. A residual transstenotic gradient of less than 15 mmHg was generally considered as a good result. Later, however, it turned out that measuring these (resting) gradients with balloon catheters was inaccurate an only had a limited prognostic value. Moreover, because there was no consistent theory to correlate pressure measurements to blood flow, the interest in measuring coronary pressures faded and disappeared almost completely with the introduction of new balloon catheters not intended for pressure measurement.

Since their discovery approximately 25 years ago, adenosine receptors have now emerged as important novel molecular targets in disease and drug discovery. These proteins play important roles in the entire spectrum of disease from inflammation to immune suppression. Because of their expression on a number of different cell types and in a number of different organ systems they play important roles in specific diseases, including asthma, rheumatoid arthritis, Parkinson’s disease, multiple sclerosis, Alzheimer’s disease, heart disease, stroke, cancer, sepsis, and obesity. As a result of intense investigations into understanding the molecular structures and pharmacology of these proteins, new molecules have been synthesized that have high specificity for these proteins and are now entering clinical trials. These molecules will define the next new classes of drugs for a number of diseases with unmet medical needs.
