  1. 11. Experimental Disruption of Intestinal Mucosal Homeostasis : Exploring the Protective Potential of Melatonin and Misoprostol

    Författare :Karsten Peters; Markus Sjöblom; Hans Lennernäs; David Dahlgren; Åsa Keita; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 12. Nitric oxide production by the intestinal mucosa during hypoperfusion

    Författare :Johan Snygg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; nitric oxide synthase; intestinal epithelium; hemorrhagic shock; cardiac tamponade; septic shock; lower body negative pressure; splanchnic circulation; substrate; laser Doppler;

    Sammanfattning : The present thesis is based on the concept that gastrointestinal blood hypoperfusion is a common phenomenon associated with critical illness. Furthermore, the development of the multiple organ dysfunction syndrome (MODS) is proposed to be initiated by gastrointestinal mucosal barrier dysfunction, allowing intestinal luminal contents to penetrate into the tissue and activate a systemic inflammatory response.

  4. 13. Epithelial barrier dysfunction in ileal Crohn's disease

    Författare :Johan Dabrosin-Söderholm; Svante Nordgren; Linköpings universitet; []

    Sammanfattning : The study aimed at investigating the intestinal barrier in Crohn's disease, with special reference to epithelial responses to luminal stimuli, and to permeation of proteins.Ileal mucosa from patients undergoing intestinal resection was studied in vitro in Ussing chambers.

  5. 14. Neuro-immuno-regulation of inflammation in the colonic mucosa : Focus on mast cells and eosinophils in bowel disorders

    Författare :Maria Teresa Casado Bedmar; Åsa Keita; Johan D Söderholm; Marie Carlson; Melanie Gareau; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mast cells; Eosinophils; Vasoactive intestinal polypeptide; Neuro-immune; Intestinal barrier; Irritable bowel syndrome; Inflammatory bowel diseases; Ussing chamber; Advance image analysis;

    Sammanfattning : Intestinal homeostasis is key to control uptake across the mucosa and protect from harmful substances. Disturbances in the bidirectional communication between the gut and the brain are implicated in irritable bowel syndrome (IBS) and inflammatory bowel diseases (IBD), being Crohn’s disease (CD) and ulcerative colitis (UC) the two most common IBD subtypes.

    Författare :Åsa Keita; Johan D. Söderholm; Ann-Charlott Ericson; Björn Weström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Corticotropin-releasing hormone; Crohn’s disease; 51Cr- EDTA; Escherichia coli; follicle-associated epithelium; horseradish peroxidase; human; ileum; inflammatory bowel disease; intestinal mucosa; mast cell; M cell; permeability; Peyer’s patches; rat; Ussing chamber; vasoactive intestinal peptide; villus epithelium; Surgery; Kirurgi;

    Sammanfattning : Crohns sjukdom är en kronisk inflammatorisk tarmsjukdom av okänd orsak. Det tidigaste tecknet på Crohns sjukdom är mikroskopiska sår i det s.k. follikelassocierade epitelet (FAE) som täcker ansamlingar av immunceller i tarmen. LÄS MER
