Available in PDF, EPUB and Kindle. Book excerpt: The microcirculation of the gastrointestinal tract is under the control of both myogenic and metabolic regulatory systems. The myogenic mechanism contributes to basal vascular tone and the regulation of transmural pressure, while the metabolic mechanism is responsible for maintaining an appropriate balance between O2 demand and O2 delivery. In the postprandial state, hydrolytic products of food digestion elicit a hyperemia, which serves to meet the increased O2 demand of nutrient assimilation. Metabolically linked factors (e.g., tissue pO2, adenosine) are primarily responsible for this functional hyperemia. The fenestrated capillaries of the gastrointestinal mucosa are relatively permeable to small hydrolytic products of food digestion (e.g., glucose), yet restrict the transcapillary movement of larger molecules (e.g., albumin). This allows for the absorption of hydrolytic products of food digestion without compromising the oncotic pressure gradient governing transcapillary fluid movement and edema formation. The gastrointestinal microcirculation is also an important component of the mucosal defense system whose function is to prevent (and rapidly repair) inadvertent epithelial injury by potentially noxious constituents of chyme. Two pathological conditions in which the gastrointestinal circulation plays an important role are ischemia/reperfusion and chronic portal hypertension. Ischemia/reperfusion results in mucosal edema and disruption of the epithelium due, in part, to an inflammatory response (e.g., increase in capillary permeability to macromolecules and neutrophil infiltration). Chronic portal hypertension results in an increase in gastrointestinal blood flow due to an imbalance in vasodilator and vasoconstrictor influences on the microcirculation.

Available in PDF, EPUB and Kindle. Book excerpt: Gastroenterology has advanced through the development and application of increasingly sophisticated methods to measure changes in gastrointestinal function. Handbook of Methods in Gastrointestinal Pharmacology brings together details on commonly employed approaches in investigative gastroenterology. The book provides comprehensive coverage of methods and techniques used to investigate the mechanism of action of drugs on the GI tract. An integral part of each chapter is the discussion of development of techniques based upon physiologic mechanisms and principles in pharmacology. In vivo and in situ techniques involving whole animals, isolated tissue methodology, the use of single cell systems, and molecular biology approaches are covered. Illustrations provide a clear understanding of methodologies discussed. Emphasis is placed on advantages and disadvantages of each technique in answering specific research questions. Chapters are written by experts experienced in the techniques they discuss; many pioneered one or more widely used methods. The wide variety of topics included make the Handbook of Methods in Gastrointestinal Pharmacology useful to established investigators, research fellows, and graduate students. Additionally, reviewers of grants and manuscripts can use it to clarify questions that arise regarding appropriate use of a technique in a particular setting.

Available in PDF, EPUB and Kindle. Book excerpt: As aging trends in the United States and Europe in particular are strongly suggestive of increasingly older society, it would be prudent for health care providers to better prepare for such changes. By including physiology, disease, nutrition, pharmacology, pathology, radiology and other relevant associated topics, Geriatric Gastroenterology fills the void in the literature for a volume devoted specifically to gastrointestinal illness in the elderly. This unique volume includes provision of training for current and future generations of physicians to deal with the health problems of older adults. It will also serve as a comprehensive guide to practicing physicians for ease of reference. Relevant to the geriatric age group, the volume covers epidemiology, physiology of aging, gastrointestinal physiology, pharmacology, radiology, pathology, motility disorders, luminal disorders, hepato-biliary disease, systemic manifestations, neoplastic disorders, gastrointestinal bleeding, cancer and medication related interactions and adverse events, all extremely common in older adults; these are often hard to evaluate and judge, especially considering the complex aging physiology. All have become important components of modern medicine. Special emphasis is be given to nutrition and related disorders. Capsule endoscopy and its utility in the geriatric population is also covered. Presented in simple, easy to read style, the volume includes numerous tables, figures and key points enabling ease of understanding. Chapters on imaging and pathology are profusely illustrated. All chapters are written by specialists and include up to date scientific information. Geriatric Gastroenterology is of great utility to residents in internal medicine, fellows in gastroenterology and geriatric medicine as well as gastroenterologists, geriatricians and practicing physicians including primary care physicians caring for older adults.

Available in PDF, EPUB and Kindle. Book excerpt: The dance along the artery The circulation on the lymph Are figured in the drift of stars. T. S. Eliot Die Methode ist alles. Carl Ludwig In physiology a spirit of finesse is required. Claude Bernard Armed with modern Doppler instrumentation, scientists can now quantify the red blood cell's "dance along the artery" as well as "the drift of stars. " In disciplines of science and medicine ranging from cardiology to astronomy, the Doppler principle now provides invaluable velo city measurements in the microcosm of capillary beds and in the cosmos. The newest appiication of the ubiquitous Doppler principle, laser-Doppler velocimetry, has been used to measure blood ftow in tissue for just a few years, but we perceived that, like most new techniques, the birth of laser-Doppler blood ftowmetry was not easy, nor was it likely to pass through infancy and reach maturity without difficulty. In physiology and medicine, better techniques for measur ing blood ftow are constantly in demand, but they often exhibit an unfortun ate boom-and-bust cyde: widespread acceptance and uncritical use are soon xiii xiv Preface followed by studies delineating the limits of the method's validity. The technique is then abandoned for the next more fashionable one, thus proving Ludwig's dictum that a given method is everything or nothing depending upon whether one can believe the data it yields.

Available in PDF, EPUB and Kindle. Book excerpt: FROM THE PREFACE:The original purpose of the First Edition of Physiology of the Gastrointestinal Tractto collect in one set of volumes the most current and comprehensive knowledge in our fieldwas also the driving force for the Fourth Edition. The explosion of information at the cellular level, made possible in part by the continued emergence of powerful molecular and cellular techniques, has resulted in a greater degree of revision than that of any other edition. The first section, now titled "Basic Cell Physiology and Growth of the Gl Tract" contains numerous new chapters on topics such as transcriptional regulation, signaling networks in development, apoptosis, and mechanisms in malignancies. Most of the chapters in this section were edited by Juanita L. Merchant. Section II has been renamed "Neural Gastroenterology and Motility" and has been expanded from seven chapters with rather classic titles to more than twenty chapters encompassing not only the movement of the various parts of the digestive tract but also cell physiology, neural regulation, stress, and the regulation of food intake. Almost all of the chapters were recruited and edited by Jackie D. Wood. The third section is entirely new and contains chapters on "Immunology and Inflammation" which were edited by Kim E. Barrett. The fourth section on the "Physiology of Secretion" consists of chapters with familiar titles, but with completely updated information to reflect the advances in our understanding of the cellular processes involved in secretion. The last section on "Digestion and Absorption" contains new chapters on the intestinal barrier, protein sorting and ion channels along with those focusing on the uptake of specific nutrients. These chapters were recruited and edited by Hamid M. Said and Fayez K. Ghishan.· Collected in one set - the most current and comprehensive coverage of gastrointestinal physiology· Information presented in a style that is both readable and understandable· Valuable to the specialized researcher, the clinical gastroenterologist, the teacher, and the student· Features an entirely new section on Immunology and Inflammation· Each section edited by the preeminent scientist in the field
