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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 24. Adsorption and Self-Assembly of Cationic Surfactants at Silica Surfaces

    Författare :Cecilia Ström; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : 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). LÄS MER

  7. 25. Adsorption of polyhydroxyl based surfactants

    Författare :Maria Matsson; Per Claesson; Robert Meszaros; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; surface chemistry; adsorption; surfactant; nonionic; alkyl glucoside APG ; ellipsometry; kinetics; alkyl amine oxide DDAO ; alkyl ammonium bromide DTAB ; solid liquid interface; synergism; coadsorption.;

    Sammanfattning : Adsorption on solid surfaces from solution is a fundamental property of a surfactant. It might even be the most important aspect of surfactant behavior, since it influences many applications, such as cleaning, detergency, dispersion, separation, flotation, and lubrication. LÄS MER
