  2. 6. Intestinal barrier function in health and disease

    Author : Pernilla Nejdfors; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; VIP.; PACAP; secretion; ion transport; urine reservoir; radiation therapy; ulcerative colitis; macromolecules; dextran; mannitol; Ussing chamber; Intestinal permeability; mucosa; Animal physiology; Djurfysiologi; Physiology; Fysiologi;

    Abstract : The intestinal epithelium has the dual function of absorbing nutrients and water as well as being a barrier to potentially harmful substances such as macromolecules and bacteria. In the present thesis the barrier function of the intestinal mucosa was studied in vitro in Ussing diffusion chambers. READ MORE

  4. 7. Aroma and Flavor in Liquid Beet Sugar Processing

    Author : Per Pihlsgård; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid beet sugar; aroma release; liquid beet sugar process; electronic nose; aroma; sensory analysis; macromolecules; flavor; GC-MS; GC-olfactometry;

    Abstract : Production of liquid beet sugar, a product of increasing importance for the food industry, involves many different compounds exhibiting aroma. Aroma compounds are introduced with the raw material, the sugar beets, but also formed as a result of sugar degradation (caramelization and Maillard reaction) or by contamination from process steps, such as adsorbents and ion exchangers.

  5. 8. Intestinal permeability : a parameter of mucosal dysfunction

    Author : Pål Lundin; Biologiska institutionen; []
    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

  6. 9. Understanding the gastrointestinal mucus and its impact on drug absorption

    Author : Vicky Barmpatsalou; Christel Bergström; Eva Karlsson; Betty Lomstein Pedersen; Hanne Mørck Nielsen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mucus; gastrointestinal; pigs; dogs; physiology; colonic; in vitro assay; drug diffusion; macromolecules;

    Abstract : The gastrointestinal mucus is a hydrogel lining the luminal side of the gastrointestinal epithelium. Mucus is vital for gut homeostasis because it protects the epithelium from the noxious external environment. READ MORE
