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 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 Handbook of Pediatric Surgery written by Chandrasen K. Sinha and published by Springer Science & Business Media. This book was released on 2010-06-25 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although pediatric surgery is a distinct and evolving specialty, it still remains an integral part of most general surgical and paediatric medical practice. Nevertheless, surgery in children does differ from adult practice in various fundamental ways, and there are key physiological and anatomical differences that constantly need underlining. Progress and improvement in outcome has also been rapid but it is sometimes difficult for practitioners to keep themselves up-to-date with the usual surgical or paediatric text books. This book will give a concise overview of all important topics and is designed to provide information in order to recognise the common surgical conditions; namely typical symptoms and signs, investigation and then treatment management. It will also provide an anatomical and physiological background to aid understanding, in addition to emphasising logical, and where possible, evidence-based practice by the use of flow charts, tables and algorithms. Authored by an international range of leading contributors, this is the first book of its kind to offer comprehensive coverage to this topic in a quick reference, pocket-book format.

Download or read book Sanitation Latrines and Intestinal Parasites in Past Populations written by Piers D. Mitchell and published by Routledge. This book was released on 2016-03-03 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sanitation and intestinal health is something we often take for granted today. However, people living in many regions of the developing world still suffer with debilitating diseases due to the lack of sanitation. Despite its clear impact upon health in modern times, sanitation in past populations is a topic that has received surprisingly little attention. This book brings together key experts from around the world to explore fascinating aspects of life in the past relevant to sanitation, and how that affected our ancestors. By its end readers will realize that toilets were in use in ancient Mesopotamia even before the invention of writing, and that flushing toilets with anatomic seats were a technology of ancient Greece at the time of the minotaur myth. They will see how sanitation compared in ancient Rome and medieval London, and will take a virtual walk around the sanitation of York at the time of the Vikings. Readers will also understand which intestinal parasites infected humans in different regions of the world over different time periods, what these parasites tell us about early human evolution, later population migrations, past diet, lifestyle, and the effects of sanitation technology. There is good evidence that over the millennia people in the past realized that sanitation mattered. They invented toilets, cleaner water supplies, drains, waste disposal and sanitation legislation. While past views on sanitation were very different to those of today, it is clear than many past societies took sanitation much more seriously than was previously thought.
