  2. 21. CO2 activation for methanol synthesis on copper and indium oxide surfaces

    Author : Alvaro Posada Borbon; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Methanol conversion; Heterogeneous catalysis; Density functional theory; Copper surface; Indium oxide​​; CO2 reduction;

    Abstract : Catalytic recycling of CO2 to added-value chemicals, such as methanol (CH3OH), has been proposed as a possible way for sustainable production of fuel and chemicals, in addition to providing a route to mitigate climate change. Multiple systems are known to be active for the conversion of CO2 to methanol, and the state of the art catalyst is Cu/ZnO/Al2O3. READ MORE

  4. 22. Characteristics of cytochrome P450-catalysed drug metabolism with focus on a black Tanzanian population

    Author : Agneta Wennerholm; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Drug metabolism; cytochrome P450; polymorphism; pharmacogenetics; genotyping; phenotyping; CYP2D6; CYP3A; debrisoquine; amodiaquine; alprazolam;

    Abstract : The cytochrome P450 (CYP) enzymes display interindividual and interethnic variability that may alter the disposition of substances metabolised by these enzymes. Both genetic and environmental factors such as concomitant drug use and concurrent diseases influence the activities of these enzymes. READ MORE

  5. 23. The role of EBNA binding proteins in cell transformation

    Author : Suhas Darekar; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Epstein-Barr virus (EBV) infects majority of the human population and maintains sub-clinical infection. However, under certain conditions it is associated with several B-cell malignancies, such as Burkitt lymphoma, Hodgkin’s lymphoma etc. READ MORE

  6. 24. Structural and Functional Studies of Diiron Carboxylate Proteins

    Author : Pål Stenmark; Pär Nordlund; Howard Dalton; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

    Abstract : Iron is essential to all life; it is a vital component of many proteins in humans as well as plants and bacteria. Because of the ability of iron to activate oxygen, it is often found in proteins that interact with oxygen in some way. READ MORE

  7. 25. Studies on sterol 27-hydroxylase (CYP27A1)

    Author : Sara von Bahr; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Human sterol 27-hydroxylase (CYP27A1) has been studied in the present thesis with focus on substrate specificity and possible role of the enzyme for prevention of accumulation of cholesterol and cholestanol in tissues. Attempts have been made to evaluate a metabolic pathway to bile acids in human primary hepatocytes that starts with a 27-hydroxylation of cholesterol catalyzed by CYP27A1. READ MORE
