3. 2. INITIATION OF EXPERIMENTAL ACUTE PANCREATITIS AND MODULATION OF INFLAMMATORY RESPONSE

   Författare :Jakob B Axelsson; Lund Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nuclear factor kappa B; neutrophils; monocytes; acute pancreatitis; ductal cells; active site-inhibited factor seven; heparan sulfate; lipopolysaccharide; innate immune response;

   Sammanfattning : Heparan sulfate (HS), a substance common in the extracellular matrix on epithelial cells is present in the pancreas, lining the duct lumen. During pathological conditions, we propose that it can be shed from the ECM and bind to receptors on the cell surface, thus triggering an inflammatory response, which if excessive can cause acute pancreatitis (AP).

4. 3. Theoretical Studies Using Simple Ionic Liquid Models

   Författare :Hongduo Lu; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Room Temperature Ionic Liquids; Coarse-Grained Models; Differential Capacitance; Monte Carlo; Classical Density Functional Theory; Room Temprerature Ionic Luqids; coarse-grained model; differential capacitance; Monte Carlo simulation; Classical Density Functional Theory;

   Sammanfattning : Room Temperature Ionic Liquids (RTILs) are organic salts that melt below 100 degrees Celsius. The advantages of RTILs, such as high ionic concentrations and low melting points, promote several potential applications. For instance, RTILs could be utilized in manufacturing energy storage devices, and as efficient solvents. LÄS MER

5. 4. Design and Synthesis of Galectin Inhibitors

   Författare :Pernilla Sörme; Barbro Kahl Knutson; U Wellmar; B-G Magnusson; Hakon Leffler; Ulf Nilsson; Yuan C. Lee; Reiko T. Lee; Centrum för analys och syntes; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parallel Synthesis; Inhibitors; Biomedicinska vetenskaper allmänt ; General biomedical sciences; Carbohydrates; Galectins;

   Sammanfattning : Galectins, a lectin family, have shown binding affinities towards b-galactosides. Galectins have been proposed to be involved in a wide range of functions like for example, cell growth, adhesion, migration, chemo taxis and apoptosis. They have also been associated with various cancer types. LÄS MER

7. 5. On Experimental and Theoretical Studies of Dynamics and Particle Production in p+Nucleus and Heavy Ion Reactions

   Författare :Anton B Fokin; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy-ion collisions; excitation function; subthreshold pion production; collective effects; entropy and chaos production; d p ratio; molecular dynamics; artificial neural networks; multifragmentation; Physics; Fysik; Fysicumarkivet A:1998:Fokin;

   Sammanfattning : Several experiments and theoretical models of intermediate energy heavy ion collision physics are presented in this thesis. Statistical and dynamical aspects of nuclear collisions are widely discussed these days, particularly in connection with the multifragmentation phenomenon and the possible link to a liquid-gas phase transition in the spinodal region of nuclear matter phase diagram.
