  • Physiology plays a major role in the scientific foundation of medicine and other subjects related to human health and physical performance. Pharmacology is the science which deals with the effects of drugs on living systems and their use in the treatment of disease. This book is designed to enhance students’ understanding of physiology and pharmacology via a series of case studies involving human disease and its treatment. Traditional university teaching methods focus on informing students in terms of physiological and pharmacological theory.

  • T he science of human nutrition and its applications to health promotion continue to gain momentum. In the relatively short time since the release of the first edition of this Encyclopedia, a few landmark discoveries have had a dramatic multiplying effect over nutrition science: the mapping of the human genome, the links between molecular bioenergetics and lifespan, the influence of nutrients on viral mutation, to name a few.

  • Given the complexity of critical care practice today, it’s impossible for even experienced clinicians to remember all the information required to give safe and effective care to critically ill patients. Clinicians frequently need to use a variety of clinical resources to verify drug information, normal laboratory and physiologic values, ECG and hemodynamic monitoring information, emergency algorithms, and other essential facts of patient management.

  • This primary text-book of applied physiology follows a natural order of treatment. In each subject elementary anatomical facts are presented in a manner which impresses function rather than form, and from the form described derives the function. The facts and principles are then applied to everyday life. Anatomy and pure physiology make clear and fix hygienic points, while applied physiology lends interest to the otherwise dry facts of physiology and anatomy.

  • Anaemia is a common complication of pulmonary tuberculosis. The precise mechanism of anaemia in pulmonary tuberculosis is not clearly known, but anaemia of inflammation as well as of Fe deficiency has been implicated. Both are common in developing countries. It is extremely difficult to distinguish anaemia of Fe deficiency from anaemia of inflammation with the haematological indices used routinely. Therefore, Fe preparations are usually prescribed for all anaemic patients irrespective of the aetiology. This approach has been questioned.

  • Previously, we isolated a 4-kDa peptide capable of binding to a 43-kDa receptor-like protein and stimulating protein kinase activity of the 43-kDa protein in soybean. Both of them were found to localize in the plasma membranes and cell walls. Here, we report the physiological effects of 4-kDa peptide expressed transiently in the cultured carrot and bird’s-foot trefoil cells transfected with pBI 121 plas-mid containing the 4-kDa peptide gene.

  • A response is to amplify the change in the variable. This has a destabilizing effect, so does not result in homeostasis. Positive feedback is less common in naturally occurring systems than negative feedback, but it has its applications. For example, in nerves, a threshold electric potential triggers the generation of a much larger action potential. Blood clotting and events in childbirth are other types of positive feedback.

  • Caffeine was conceived for a wide range of readers interested in the effects on human health, nutrition, and physiological function of the methylxanthine beverages and foods—tea, coffee, maté, cola beverages, and cocoa and chocolate products. These products supply one or more of the dietary methylxanthines—caffeine, theobromine and theophylline— and are an integral part of the diet of many people in many countries. The interest in the health effects of both the methylxanthines in isolation and in the products containing them has grown rapidly in recent years.

  • The all-too-common conditions this woman and her children face illustrate how health programs and weak systems in many developing countries are not meeting needs. Although health services may be available, too often they are of poor quality and are provided in an uncoordinated or ad hoc manner. Often, they are organized around funding sources or diseases, rather than in a way that addresses the broader needs of the populations they seek to serve.

  • Chemical oxidation technologies are predominantly used to address contaminants in the source area saturated zone and capillary fringe. Cost concerns can preclude the use of chemical oxidation technologies to address large and dilute petroleum contaminant plumes. More frequently, chemical oxidation technologies are employed to treat smaller source areas where the petroleum mass is more concentrated.

  • MINERAL NUTRIENTS ARE ELEMENTS acquired primarily in the form of inorganic ions from the soil. Although mineral nutrients continually cycle through all organisms, they enter the biosphere predominantly through the root systems of plants, so in a sense plants act as the “miners” of Earth’s crust (Epstein 1999). The large surface area of roots and their ability to absorb inorganic ions at low concentrations from the soil solution make mineral absorption by plants a very effective process.
