  1. 16. Signal transduction in human phagocytic cells during phagocytosis, oxidative activation and apoptosis

    Författare :Maria Forsberg; Emmanuelle Caron; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Neutrophils and macrophages are professional phagocytic cells that play a crucial role in host defense against invading microorganisms. They bind to, internalize, and subsequently kill microbes with an arsenal of reactive oxygen metabolites and microbicidal agents. LÄS MER

  3. 17. Immunity to Salmonella infection

    Författare :Cecilia Johansson; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; serology; transplantation; Immunologi; serologi; cytokines; antigen presentation; liver; dendritic cells; Salmonella; gram negative bacteria;

    Sammanfattning : The immune system has several strategies to combat infections. The present study investigates various aspects of the interaction between Gram negative bacteria, particularly Salmonella, and antigen presenting cells (APC). Salmonella is an intracellular bacterium infecting mice and man. LÄS MER

  4. 18. Properties of some chlorinated polycyclic aromatic hydrocarbons with respect to chemical analysis

    Författare :Ulrika Nilsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes chemical and biological properties of chloro-added and chloro-substituted PAHs with respect to chemical analysis. The work includes biological testing with Ames assay, study of chemical reactivities in chlorination reactions and retention characteristics on normal phase stationary phases for HPLC, as well as analysis of urban air samples with respect to chlorinated PAHs (Cl-PAHs).

  5. 19. Studies on the coiled-coil protein TlpA in salmonella : a thermosensing transcription autoregulator

    Författare :Reini Hurme; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :coiled-coilgene regulationrepressorthermoregulationSalmonella;

    Sammanfattning : The coiled-coil motif is composed of amino acid heptad repeats with hydrophobic or apolar residues at conserved positions. Such repeats are responsible for the apolar stripe that is buried inside the coiled-coil structure formed upon coiling of two (or more) alpha-helical chains about each other. LÄS MER

  7. 20. Protection of Biomolecules by Antioxidants - Mechanisms and Applications

    Författare :Carl Grey; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dG; antioxidants; mass spectrometry; Analytical chemistry; Analytisk kemi; Food and drink technology; Livsmedelsteknik; Bioteknik; Biotechnology; DNA; Oxidation; Protein; Fenton reaction;

    Sammanfattning : Reactive oxygen species (ROS) consisting of various oxygen-based free radicals as well as other reactive non-radical species produced in O2-related metabolism or through other processes are involved in the oxidation of such vital biomolecules as DNA, proteins and lipids. The types of oxidation represented here are known to cause many different diseases and disorders in human beings, such as cancer, Alzheimer's disease and ageing. LÄS MER
