  1. 26. Angiogenesis regulation in hormone dependent breast- and ovarian cancer

    Författare :Christina Bendrik; Charlotta Dabrosin; Malin Sund; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Angiogenesis is a key event in tumor progression and a rate-limiting step in the establishment of a clinical cancer disease. The net balance of pro- and anti-angiogenesis mediators in the tissue dictates the angiogenic phenotype of a tumor. LÄS MER

  3. 27. Characterisation of Time-dependent Statistical Failure of Fibre Networks : Applications for Light-weight Structural Composites

    Författare :Amanda Mattsson; Tetsu Uesaka; Christina Dahlström; Sören Östlund; Mittuniversitetet; []
    Nyckelord :;

    Sammanfattning : The future of a sustainable society requires that materials not only be renewable, but also leave as small a carbon foot-printin the environment as possible. One such product is light-weight composite material for transportation packages. Cellulose fibres have been and will continue to be ideal for this purpose. LÄS MER

  4. 28. T cell dependent B lymphocyte activation, growth and maturation : the role of lymphokines

    Författare :Sven Pettersson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TH cell activated B- cell growth maturation B-cell growth factor BSF-pI B-cel1 maturation factor s BMA neonatal B-cell prol iferation anti body secretion;

    Sammanfattning : The present work concerns the regulation of B cell activation, growth and terminal differentiation of helper T cells.T cell dependent (TD) B cell activation requires physical cell to cell contact between competent helper T cells (TH) and B cells and the recognition of MHC Class II antigens.

  5. 29. Exploring mTOR-dependent regulation of mRNA translation in cancer

    Författare :Hui Liu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Modulation of mRNA translation via the mammalian target of rapamycin (mTOR) pathway is primarily achieved by integrating internal or external signals onto the translation machinery, especially on the rate-limiting initiation step during mRNA translation. Subsets of transcripts are discriminated by structural and/or sequence features, and encode proteins involved in different biological functions. LÄS MER

  7. 30. Radiation Induced Oxidative Dissolution of UO2

    Författare :Ella Ekeroth; Mats Jonsson; Bernd Grambow; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radiation; radiolysis; UO2; spent nuclear fuel; radicals; oxidants; reductants; rate constants; dissolution; H2O2; H2; Nuclear chemistry; Kärnkemi;

    Sammanfattning : Sammanfattning Denna doktorsavhandling berör oxidativ upplösning av UO2 (som modellsubstans för utbränt kärnbränsle) orsakad av radiolys av vatten samt effekten av H2 på denna denna process. Hastighetskonstanter för oxidation av UO2-pulver med olika oxidanter såsom H2O2 har bestämts experimentellt. LÄS MER
