Available in PDF, EPUB and Kindle. Book excerpt: Gastrointestinal Tissue: Oxidative Stress and Dietary Antioxidants brings together leading experts from world renowned institutions, combining the basic mechanisms of gastrointestinal diseases with information regarding new and alternative treatments. The processes within the science of oxidative stress are described in concert with other processes, including apoptosis, cell signaling and receptor mediated responses, further recognizing that diseases are often multifactorial with oxidative stress as a component. By combining the critical molecular processes underlying free radical mediated pathologies and the role of dietary antioxidant molecules, a connection is made that helps advance therapies and the prevention of gastrointestinal pathological processes. This important reference is well designed with two complementary sections. Section One, Oxidative Stress and Gastroenterology, covers the basic processes of oxidative stress from molecular biology to whole organs, the gastrointestinal anatomy and sources of oxidative stress and free radicals and their products in gastrointestinal diseases. Section Two, Antioxidants and Gastroenterology covers antioxidants in foods, including plants and components. Covers the science of oxidative stress in gastrointestinal tissue and associated conditions and scenarios Provides information on optimal levels for human consumption of antioxidants, suggested requirements per day, recommended dietary allowances and curative/preventive effects of dietary antioxidants Presents an easy to reference guide with two complementary sections that discuss the pathophysiology of gastrointestinal diseases in relation to oxidative stress and antioxidant therapies

Download or read book Regulation of Gastrointestinal Mucosal Growth written by Rao N. Jaladanki and published by Biota Publishing. This book was released on 2016-11-30 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mammalian gastrointestinal mucosa is a rapidly self-renewing tissue in the body, and its homeostasis is preserved through the strict regulation of epithelial cell proliferation, growth arrest, and apoptosis. The control of the growth of gastrointestinal mucosa is unique and, compared with most other tissue in the body, complex. Mucosal growth is regulated by the same hormones that alter metabolism in other tissues, but the gastrointestinal mucosa also responds to host events triggered by the ingestion and presence of food within the digestive tract. These gut hormones and peptides regulate the growth of the exocrine pancreas, gallbladder epithelium, and the mucosa of the oxyntic gland region of the stomach and the small and large intestines. Luminal factors, including nutrients or other dietary factors, secretions, and microbes that occur within the lumen and distribute over a proximal-to-distal gradient, are also crucial for maintenance of normal gut mucosal regeneration and could explain the villous-height-crypt-depth gradient and variety of adaptation, since these factors are diluted, absorbed, and destroyed as they pass down the digestive tract. Recently, intestinal stem cells, cellular polyamines, and noncoding RNAs are shown to play an important role in the regulation of gastrointestinal mucosal growth under physiological and various pathological conditions. In this book, we highlight key issues and factors that control gastrointestinal mucosal growth and homeostasis, with special emphasis on the mechanisms through which epithelial renewal and apoptosis are regulated at the cellular and molecular levels.

Download or read book The Gastrointestinal Circulation written by Peter R. Kvietys and published by Morgan & Claypool Publishers. This book was released on 2010 with total page 127 pages. 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.

Download or read book Colonic Motility written by Sushil K. Sarna and published by Biota Publishing. This book was released on 2010-11-01 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three distinct types of contractions perform colonic motility functions. Rhythmic phasic contractions (RPCs) cause slow net distal propulsion with extensive mixing/turning over. Infrequently occurring giant migrating contractions (GMCs) produce mass movements. Tonic contractions aid RPCs in their motor function. The spatiotemporal patterns of these contractions differ markedly. The amplitude and distance of propagation of a GMC are several-fold larger than those of an RPC. The enteric neurons and smooth muscle cells are the core regulators of all three types of contractions. The regulation of contractions by these mechanisms is modifiable by extrinsic factors: CNS, autonomic neurons, hormones, inflammatory mediators, and stress mediators. Only the GMCs produce descending inhibition, which accommodates the large bolus being propelled without increasing muscle tone. The strong compression of the colon wall generates afferent signals that are below nociceptive threshold in healthy subjects. However, these signals become nociceptive; if the amplitudes of GMCs increase, afferent nerves become hypersensitive, or descending inhibition is impaired. The GMCs also provide the force for rapid propulsion of feces and descending inhibition to relax the internal anal sphincter during defecation. The dysregulation of GMCs is a major factor in colonic motility disorders: irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and diverticular disease (DD). Frequent mass movements by GMCs cause diarrhea in diarrhea predominant IBS, IBD, and DD, while a decrease in the frequency of GMCs causes constipation. The GMCs generate the afferent signals for intermittent short-lived episodes of abdominal cramping in these disorders. Epigenetic dysregulation due to adverse events in early life is one of the major factors in generating the symptoms of IBS in adulthood.

Download or read book Modern Concepts in Gastroenterology written by Eldon Shaffer and published by Springer. This book was released on 2011-09-30 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once again the gastroenterologists of northwestern Canada have come out with a series of essays advancing important modem concepts. As indefatigable as ever, they bring together the latest in clinical-pathophysiological considera tions for the clinician. The topics run the gamut from the lovely liver to HIV infection, from the pathophysiology of bile flow to comments on antigens in colorectal cancer. It is always easy to publish a first volume, for enthusiasm is high and everyone is anxious to win a place. Bringing out a second volume, the carrying forward of a good idea, is so much harder. In many ways this second volume in the series marks the coming of age of Canadian gastroenterology, as 11 of the 21 contributors currently reside in Canada. Still, the contributions from the United Kingdom and the United States make this an Anglo-American festival. Reading the chapters will make you appreciate the care with which the contributors have garnered recent references to give up-to-date practical infor mation for us all. I enjoyed all that I read. My congratulations to Drs. Shaffer and Thomson for a job well done. Howard M. Spiro, M.D. New Haven, Connecticut ix Preface This book is based on papers presented at the third symposium on Recent Ad vances in Gastroenterology held by the Canadian Association of Gastroenter ology. The proposed audience for this volume is the internist and the general surgeon, as well as those in the specialties of gastroenterology and hepatology.
