  1. 6. 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

  3. 7. Small-Molecule Galectin Ligands : Structure-Based Optimisation of Affinity and Selectivity

    Författare :Sjors Van Klaveren; Centrum för analys och syntes; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Galectins; structure activity relation;

    Sammanfattning : In the body, all cell surfaces are covered with glycans, and many regulatory components havecarbohydrates attached to them, which can aid in their function. Galectins are a family of proteins whichcan bind to specific glycans and oligosaccharides and cross-link them to influence a wide range of cellularprocesses. LÄS MER

  5. 9. Development of Simultaneous Saccharification and Fermentation for Production of Ethanol from Softwood

    Författare :Malek Alkasrawi; Centrum för analys och syntes; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Kemiteknik och kemisk teknologi; spruce; softwood; fermentation; cultivation; Tween-20; SSF; recirculation; Ethanol production; process streams;

    Sammanfattning : This thesis deals with the development of simultaneous saccharification and fermentation (SSF) in order to improve the economy of the softwood-to-ethanol process. The effect of process stream recirculation on ethanol production from steam-pretreated softwood based on SSF was investigated for two process cases. LÄS MER
