    Sammanfattning : Studies on the Mechanism for Natural Killer Cell Cytotoxicity and Its Regulation Lin-Sheng Xiao Dissertation from the Unit for Applied Biochemistry, Clinical Research Center, Karolinska Institute, Stockholm, Sweden Since the proposed perforin-granzymes exocytosis can not sufficiently account for NK cell mediated cytolysis, the existence of a new and yet unknown mechanism for induction of the damage to targets by NK cells has been suggested. Our data illustrates that NK cell oncolytic activity has a requirement for L-arginine. LÄS MER

    Sammanfattning : Developments in communication and data storage technologies have made large-scale data collection more accessible than ever. The transformation of this data into insight or decisions typically involves solving numerical optimization problems. LÄS MER

  3. 3. Performance of MCrAlX coatings : Oxidation, Hot corrosion and Interdiffusion

    Författare :Pimin Zhang; Ru Lin Peng; Xin-Hai Li; Sten Johansson; Ping Xiao; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : MCrAlY coatings (M=Ni and/or Co) are widely used for the protection of superalloy components against oxidation and hot corrosion in the hot sections of gas turbines. The drive for coating systems to bestow adequate oxidation and corrosion resistance upon the components becomes urgent as an inevitable result of the necessary improvement in engine combustion efficiency and service lifetime.

  4. 4. Caenorhabditis elegans as a model to elucidate host-pathogen interactions for human bacterial pathogens

    Författare :Xiao Hui Sem; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : The soil nematode Caenorhabditis elegans is a popular host utilized to model bacterial virulence and microbial pathogenesis in vivo. This thesis explores the use of C. elegans for the study of host-pathogen interactions for two Gram-negative bacteria, Burkholderia thailandensis and Salmonella enterica. LÄS MER
