  1. 1. Immunomodulation by estrogen and estren

    Författare :Ulrika Islander; Göteborgs universitet; []
    Nyckelord :estrogen receptor knock-out mice; estrogen; estren; estrogen receptor; lymphopoiesis; T cells; B cells; immunoglobulin; inflammation;

    Sammanfattning : Estrogen affects the development and regulation of the immune system. Treatment of gonadectomized mice with estrogen results in suppression of T and B lymphopoiesis, as well as decreased delayed type hypersensitivity reaction, granulocyte mediated inflammation and levels of IL-6 in serum.

  2. 2. Functional analysis of ligand recognition by the glucocorticoid receptor

    Författare :Ulrika Lind; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :glucocorticoid receptor; steroid-binding; site-directed mutagenesis; protein-ligand interaction; mechanism of glucocorticoid action;

    Sammanfattning : The glucocorticoid receptor (GR) is a ligand-inducible transcription factor that belongs to the superfamily of nuclear hormone receptors. It contains three structural and functional domains. LÄS MER

  3. 3. Regulation of hematopoiesis by the Smad signaling pathway

    Sammanfattning : Hematopoietic stem cells (HSCs) reside in the bone marrow (BM) of adult individuals and are ultimately responsible for the continuous production of blood cells throughout life. The regulation of HSCs in vivo is tightly regulated by both intrinsic and extrinsic factors. LÄS MER

  4. 4. Synthesis of nano sized Cu and Cu-W alloy by hydrogen reduction

    Författare :Ulrika Tilliander; Seshadri Seetharaman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen reduction; kinetics; activation energy; copper oxide; copper tungsten composite; alloy powder; manostructure; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : The major part of the present work, deals with the reduction kinetics of Cu2O powder and a Cu2O-WO3 powder mixture by hydrogen gas, studied by ThermoGravimetric Analysis (TGA). The reduction experiments were carried out both isothermally and non-isothermally on thin powder beds over different temperature intervals. LÄS MER
