  2. 1. 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

  4. 2. The role of computer-aided design and surface chemistry on Cell-scaffold interactions

    Author : Sun Yang; Anna Finne-Wistrand; Ann-Christine Albertsson; Jinshan Pan; My Hedhammar; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; amorphous degradable copolymer; aliphatic polyester; 3D fiber deposition; computer-aided design; Tween 80; BMSC; hOB; porous scaffolds;

    Abstract : Cell interactions and cell response to three dimensional scaffolds based on poly(L-lactide-co-1,5-dioxepan-2-one) [poly(LLA-co-DXO)] and poly(L-lactide-co-e-caprolactone) [poly(LLA-co-CL)] wereimprovedstudiedby increasing surface hydrophilicity and by using computer-aided scaffold design. Different amounts of Tween 80 (3, 10, 20 wt%) were mixed with the copolymer and it was found that the water contact angle decreased significantly with the amount of Tween 80. READ MORE

  5. 3. Engineering and Functionalization of Degradable Scaffolds for Medical Implant Applications

    Author : Yang Sun; Anna Finne-Wistrand; Ann-Christine Albertsson; Minna Kellomäki; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tissue engineering; nanodiamond; scaffold; bioreactor; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The treatment of bone defects is facing the situation of lacking donations for autotransplantation. As a valid approach, scaffold-based tissue engineering combines the construction of well-defined porous scaffolds with advanced cell culturing technology to guide tissue regeneration. READ MORE

  6. 4. Microsomal glutathione transferase : studies on the kinetic mechanism, species variety, binding properties and substrate measurement

    Author : Tie-Hua Sun; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Microsomal glutathione transferase (MGST) is a membrane bound detoxification enzyme, which has been purified from different species including rat, mouse, human, frog, and fish. The rat MGST1 is localized predominantly in the liver microsomes and the outer mitochondrial membrane. READ MORE

  7. 5. Roles of membrane vesicles in bacterial pathogenesis

    Author : Svitlana Vdovikova; Sun Nyunt Wai; Richard Lundmark; Ann-Beth Jonsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane vesicles; autophagy; pore-forming toxin; pore formation; Listeria monocytogenes; Vibrio cholerae; virulence factor; PrtV protease; listeriolysin O; V. cholerae cytolysin; mikrobiologi; Microbiology; molekylärbiologi; Molecular Biology;

    Abstract : The production of membranous vesicles is observed to occur among organisms from all domains of the tree of life spanning prokaryotes (bacteria, archaea) and eukaryotes (plants, animals and fungi). Bacterial release of membrane-derived vesicles (MVs) has been studied most extensively in cases of Gram-negative species and implicating their outer membrane in formation of extracellular MVs.
