  1. 1. Gut peptides in gastrointestinal motility and mucosal permeability

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Md. Abdul Halim; Webb Dominic-Luc; Per M Hellström; Lars Fändriks; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gut regulatory peptides; Neuropeptides; Gastrointestinal mucosal permeability; Gastrointestinal motility; GLP-1; NPS; ROSE-010;

    Abstract : Gut regulatory peptides, such as neuropeptides and incretins, play important roles in hunger, satiety and gastrointestinal motility, and possibly mucosal permeability. Many peptides secreted by myenteric nerves that regulate motor control are also produced in mucosal epithelial cells. READ MORE

  2. 2. Gastrointestinal Permeability and Motility in Inflammatory Bowel Disease

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anas Kh. Al-Saffar; Per Hellström; Dominic-Luc Webb; Åsa Keita; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gastrointestinal motility; intestinal permeability; Mucosal; Ghrelin; Medicinsk vetenskap; Medical Science;

    Abstract : Synchronized motility, permeability and secretory (hormones and enzymes) events are integral to normal physiology. Smooth muscle syncytium operates with enteric nervous system (ENS) and endocrine signalling to accommodate, mix and control passage of ingested materials. READ MORE

  3. 3. Intestinal permeability : a parameter of mucosal dysfunction

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Pål Lundin; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peptide; N-acetylcysteine; Medium-chain glyceride; Mannitol; Macromolecules; Lipid; Kinetics; In vivo; In vitro; In situ; Intestine; Injury; Inflammation; HLA-B27; HCl; Epithelium; Enhancer; dDAVP; 51Cr-EDTA; BSA; Absorption; Albumin; Permeability; Animal physiology; Djurfysiologi;

    Abstract : The gastrointestinal tract has two opposing functions; to absorb nutrients and electrolytes, and to act as a barrier towards hazardous and non-nutritional substances. In the present thesis the barrier function of the gastrointestinal tract was studied in animal models in vivo, in situ and in vitro. READ MORE

  4. 4. Nitrate, Nitrite and Nitric Oxide in Gastric Mucosal Defense

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Joel Petersson; Uppsala universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dietary nitrate; mucus gel layer; mucosal blood flow; mucus thickness; laser-Doppler flowmetry; mucosal damage; intra-vital microscopy; mucosal permeability; ODONTOLOGY Physiology; ODONTOLOGI Fysiologi;

    Abstract : The human stomach normally contains high levels of bioactive nitric oxide (NO). This NO derives from salivary nitrate (NO3-) that is converted to nitrite (NO2-) by oral bacteria and thereafter non-enzymatically reduced in the acidic gastric lumen to NO. READ MORE

  5. 5. Regulation of Duodenal Mucosal Barrier Function and Motility The Impact of Melatonin

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Sommansson; Markus Sjöblom; Olof Nylander; Oliver Bachmann; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 51Cr-EDTA; bicarbonate secretion; duodenum; enteric nervous system; enterochromaffin cell; ethanol; hexamethonium; in vivo; mecamylamine; motility; mucosal permeability; parecoxib; rat; Physiology; Fysiologi;

    Abstract : The duodenal mucosa is regularly exposed to acid, digestive enzymes and ingested noxious agents. It is thus critical to maintain a protective barrier to prevent the development of mucosal injury and inflammation, which are often observed in situations when barrier function is impaired. READ MORE
