  3. 7. Genetic regulation of autoimmune neuroinflammation

    Författare :Kristina Becanovic; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MS; EAE; QTL; gene regulation; linkage analysis;

    Sammanfattning : Multiple sclerosis (MS) is a complex disease characterized by inflammation and demyelination in the central nervous system (CNS), causing neurological deficits. Although there is an increased familial aggregation rate and evidence for a genetic influence on disease susceptibility, environmental factors are also of importance. LÄS MER

  4. 8. On the Optimisation and Regulation of Clinical Trials

    Författare :Sebastian Jobjörnsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; decision theory; Bayesian statistics; optimal stopping.; clinical trials; subgroup analysis; drug regulation;

    Sammanfattning : The basic premise of this thesis is that Bayesian Decision Theory (BDT) can and should be used to solve clinical trial design problems. While the flexibility of the framework allows for accommodating a great variety of situations, it also requires an explicit consideration of the gains and costs associated with the trial. LÄS MER

  5. 9. Regulation of gene expression in the vascular wall

    Författare :Erik Larsson; Göteborgs universitet; []
    Nyckelord :smooth muscle; endothelium; angiogenesis; SRF; myocardin; LPP; gene regulation; genetics; microRNA;

    Sammanfattning : Blood vessel growth and function are closely related to a number of pathological conditions, including tumor angiogenesis, wound healing and atherosclerosis. Smooth muscle cells (SMC) and endothelial cells (EC), the two major constituents of the vascular wall, are both characterized by the expression of unique phenotypic marker genes, many of which have vital roles in blood vessel development and disease.

  7. 10. Regulation of Hematopoietic Stem Cells

    Författare :Emma Rörby; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoiesis; hematopoietic stem cells; hematopoietic stem cell expansion; cord blood; transforming growth factor beta; Smad signaling; pigment epithelium derived factor; CD9;

    Sammanfattning : This thesis is about the regulation of hematopoietic stem cells (HSCs) that represent rare cells residing in the bone marrow (BM) of adults. They are multipotent cells that have the capacity to differentiate to all mature cells of the blood system and have the capacity to self-renew, i.e. generate new HSCs. LÄS MER
