  2. 21. Theoretical Studies of Drug-Metabolizing Cytochrome P450 Enzymes

    Author : Junhao Li; Yaoquan Tu; Ulf Ryde; KTH; []
    Keywords : Cytochrome P450 enzymes; molecular dynamics; quantum chemistry; structural flexibililty; ONIOM; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : The family of cytochrome P450 enzymes (P450s) belongs to one of the most important enzyme families in the human body. P450s are involved in the synthesis of endogenous compounds and metabolism of exogenous substances. READ MORE

  4. 22. Violaxanthin De-epoxidase and the Xanthophyll Cycle

    Author : Anna Gisselsson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; zeaxanthin.; xanthophyll cycle; violaxanthin de-epoxidse; thylakoid; regulation; quenching; protonation; pH-dependence; light stress; histidine; Conformational change; domains; Växtbiokemi;

    Abstract : The xanthophyll cycle is a mechanism for short term adaptation of plants to varying light intensities. It involves a reversible conversion of violaxanthin to zeaxanthin, via the intermediate antheraxanthin, upon high light intensities. READ MORE

  5. 23. The role of intestinal dendritic cells and the microbiota during oral Salmonella infection

    Author : Maria Fernández-Santoscoy; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salmonella; dendritic cells; NK-kB; MyD88; CD40; CD103; IRF4; microbiota;

    Abstract : The intestinal pathogen Salmonella causes millions of infections per year worldwide. The immune response to these bacteria involves interactions between several cell types via specific molecules and is under the influence of the intestinal microbiota. Dendritic cells (DC) initiate immune responses including those to Salmonella. READ MORE

  6. 24. TRÖGER´S BASE AS SCAFFOLD FOR SYNTHETIC RECEPTORS

    Author : Carlos Solano; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Organisk kemi; Organic chemistry; Makromolekylär kemi; Macromolecular chemistry; Molecular Recognition; Tröger´s base; Synthetic Receptors; Fysikalisk kemi;

    Abstract : This work focuses on the use of the Tröger´s base as organic scaffold for the construction of synthetic receptors for different classes of organic molecules. The structural properties of the Tröger's base, i.e. chirality, rigidity and curvature, allow for synthetic modifications towards the recognition of different molecules. READ MORE

  7. 25. Adsorption and Self-Assembly of Cationic Surfactants at Silica Surfaces

    Author : Cecilia Ström; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi;

    Abstract : The equilibrium self-assembly of cationic surfactants in bulk solution and at negatively-charged silica substrates is investigated experimentally and theoretically. The surfactants used are quaternary ammonium salts, both monovalent (DoTAB, TTAB, CTAB) and divalent (DoPPDAC). READ MORE
