  2. 6. Regulation of Duodenal Mucosal Barrier Function and Motility : The Impact of Melatonin

    Author : Anna Sommansson; Markus Sjöblom; Olof Nylander; Oliver Bachmann; Uppsala universitet; []
    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.

  5. 8. Biopharmaceutical aspects of intestinal drug absorption : Regional permeability and absorption-modifying excipients

    Author : David Dahlgren; Hans Lennernäs; Erik Sjögren; Bertil Abrahamsson; Christer Tannergren; Steffansen Bente; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intestinal permeability; absorption-modifying excipients; Biofarmaci; Biopharmaceutics;

    Abstract : Before an orally administered drug reaches the systemic circulation, it has to dissolve in the intestinal fluids, permeate across the intestinal epithelial cell barrier, and pass through the liver. The permeation rate of drug compounds can be low and show regional differences.The thesis had two general aims. READ MORE

  6. 9. Experimental Disruption of Intestinal Mucosal Homeostasis : Exploring the Protective Potential of Melatonin and Misoprostol

    Author : Karsten Peters; Markus Sjöblom; Hans Lennernäs; David Dahlgren; Åsa Keita; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intestinal barrier dysfunction; intestinal permeability; chemotherapy-induced mucositis; doxorubicin; 5-fluorouracil; apoptosis; proliferation; melatonin; misoprostol; Medicinsk vetenskap; Medical Science;

    Abstract : The intestinal mucosa serves as a protective layer that separates the intestinal contents from the underlying tissues. It restricts harmful substances, pathogens, and undigested particles from entering the bloodstream. READ MORE

  7. 10. Neural control of colonic epithelial transport, motility and permeability in vivo. An experimental study in anaesthetized rats

    Author : Ying Sun; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enteric nervous system; colonic motility; transmural potential difference; net; fluid transport; permeability; bile acid; nitric oxide; inflammatory bowel disease;

    Abstract : Colonic dysfunction may result in diarrhoea, abdominal pain or constipation, andinflammatory bowel disease, bile acid malabsorption and particularly irritable bowelsyndrome are very common disorders. The role of the enteric nervous system (ENS) inthese diseases is largely unknown. READ MORE
