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.

Available in PDF, EPUB and Kindle. Book excerpt: "Prior to the development of the first fibre-optic endoscopes in the 1960's, gastroenterology, in common with other traditional medical specialties, relied on biochemical and radiological techniques in order to investigate the gastrointestinal tract. Histological confirmation of a disease process usually required the presence of a surgeon, was invasive, and carried inherent risks. Because of a rapid improvement in technology, we are now able to sample the entire gastrointestinal tract from the mouth and anus through to the ileal / jejunal junction"--

Download or read book Surgical Pathology of Non neoplastic Gastrointestinal Diseases written by Lizhi Zhang and published by Springer. This book was released on 2019-06-24 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the entire spectrum of non-neoplastic diseases within the gastrointestinal (GI) tract including new entities, recent developments, and questions that arise in the practice of GI pathology. The text is organized by specific organ site, with related disorders of each organ site subgrouped into several chapters based on their common features. Pathologists can quickly find the disorders they are interested and review similar disorders in the same chapter to help them make a correct diagnosis. Each major and common entity is described in detail with its definition, clinical features, pathological features (covering both the gross and microscopic details), differential diagnosis and treatment/prognosis. All chapters also highlight the use of special/immunohistochemical stains and other supporting studies as needed with a focus on providing a practical differential diagnosis rather than just a list of potential associations. This book is extensively illustrated with both gross and microscopic images that act as an integral part of the information provided in the text. Written by practicing GI/liver pathologists and gastroenterologists from the Mayo Clinic, Surgical Pathology of Non-neoplastic Gastrointestinal Diseases serves as a comprehensive yet practical guide for diagnostic surgical pathologists with a passion for GI pathology.
