  1. 1. Surfactants based on natural products - enzymatic synthesis and functional characterization

    Författare :Fredrik Viklund; KTH; []
    Nyckelord :Enzymatic synthesis; Surfactants; Antioxidants; Ascorbyl oleate; Polyethylene glycol PEG esters; Hemolysis; Transepithelial electrical resistance; Ionic liquids; Candida antarctica lipase B;

    Sammanfattning : Surfactants are molecules that contain a water-soluble and afat-soluble part. They have important functions in productssuch as detergents, cosmetics, pharmaceuticals and foods aswell as in many industrial processes. Surfactants are used onvery large scale, which makes it important to decrease theirimpact on the environment. LÄS MER

  3. 2. Role of Neutrophils and Innate Immune Mechanisms in Urinary Tract Infections

    Författare :Björn Frendéus; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mikrobiologi; mycology; virology; bacteriology; Microbiology; Mucosal immunology; Infection Resistance; Neutrophils; Toll-like receptors; Urinary Tract Infections; Chemokine receptors; bakteriologi; virologi; mykologi;

    Sammanfattning : Urinary tract infections (UTI) are among the most common infections in man. Despite their prevalence, information on the molecular mechanisms defects that explain the increased susceptibility to disease are lacking. LÄS MER

  4. 3. On the Regulation of the Epithelial Paracellular Permeability

    Författare :Pia Nybom; Janove Sehlin; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The epithelia of for instance the small intestine(s) plays a crucial role in the vectorial transport of nutrients and other solutes from the lumen to underlying body fluids, i.e. blood and lymph. LÄS MER

    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.

  7. 5. The mucus layer and other barriers to intestinal drug absorption

    Författare :Agneta Wikman Larhed; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; galenisk farmaci; Pharmaceutics;

    Sammanfattning : The extraepithelial mucus layer acts as a barrier to the absorption and diffusion of drugs. Three in vitro models have been used for studies of this and other intestinal barriers to drug transport. A drug absorption model based on monolayers of the mucus-producing human intestinal goblet HT29-H cell line was developed. LÄS MER
