  1. 11. Tumor necrosis factor superfamily members CD137 and OX40 ligand in vascular inflammation

    Författare :Leif Söderström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Atherosclerosis, an inflammatory disease, is the major cause of cardiovascular disease - the main cause of death worldwide. T cells are central orchestrators of inflammation in atherosclerosis and critically depend on costimulation for adequate function. LÄS MER

  3. 12. Prognostic factors in soft tissue sarcoma. Tissue microarray for immunostaining, the importance of whole-tumor sections and time-dependence

    Författare :Jacob Engellau; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; growth pattern; time-dependence; P-glycoprotein Pgp ; CD44; β-catenin; cyclin A; bcl-2; p53; Ki-67; immunohistochemistry IHC ; whole-tumor sections; tissue microarray TMA ; Soft tissue sarcoma; prognostic factors; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

    Sammanfattning : In adult soft tissue sarcoma (STS) of the extremities and trunk wall, improved prognostic factors are needed to identify patients at high-risk for metastasis. Various factors are included in the many prognostic systems currently in use and the prognostic value of immunohistochemical (IHC) expression of biological markers is unclear. LÄS MER

  4. 13. Regional fluxes of tissue plasminogen activator in porcine endotoxemia

    Författare :Annette Nyberg; Göteborgs universitet; []
    Nyckelord :pig; endotoxin; tissue type plasminogen activator; plasminogen activator inhibitor; tumor necrosis factor ?;

    Sammanfattning : Formation of fibrin clots in the microcirculation during severe sepsis contributes to organ failure, frequently involving the lungs and the splanchnic organs. Tissue type plasminogen activator, tPA, is the key activator of intravascular fibrinolysis with plasminogen activator inhibitor type-1, PAI-1, as its main inhibitor. LÄS MER

  5. 14. Hematopoietic stem cells: c-mpl and TNF receptor function

    Författare :Veslemøy Ramsfjell; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tumor necrosis factor-a.; in vivo reconstitution; ex vivo expansion; long-term bone marrow culture; differentiation; proliferation; synergy; Hematopoietic stem cells; thrombopoietin; Haematology; extracellular fluids; Hematologi; extracellulära vätskor;

    Sammanfattning : Hematopoietic stem cells (HSC) are crucial to life. Daily and throughout the life span of an individual they are responsible for replacing approximately 10(12) mature blood cells. Mature cells are, for example, required for transportation of oxygen, defense against infections and to stop bleeding. LÄS MER

  7. 15. Early Blood Cell Formation "in sickness and health, ´till death do us part"

    Författare :Kees-Jan Pronk; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic stem cell; differentiation; regulation; myeloerythropoeisis; myelopoesis; p16INK4A; aging; tumor necrosis factor;

    Sammanfattning : Hematopoietic stem cells (HSC), the ancestors of all blood cells, have the ability to give rise to mature effector cells through a series of developmental steps. This is a tightly regulated, though a highly dynamic process: on the one hand, dysregulation in steady-state could lead to under- or overgrowth of certain blood cell lineages, whereas, on the other hand, demands for certain mature blood cells can change dramatically in cases like bleeding and infections.
