  1. 1. Remodelling of extracellular matrix in rectal cancer and preoperative radiotherapy

    Författare :Eva Angenete; Göteborgs universitet; []
    Nyckelord :radiotherapy; rectal cancer; extracellular matrix; MMP-2; PAI-1; uPA; Calprotectin; TGF-beta1;

    Sammanfattning : BACKGROUND Preoperative radiotherapy reduces local recurrence due to rectal cancer, but increases postoperative morbidity. The aim of this thesis was to study the impact of radiotherapy on extracellular matrix (ECM) remodelling enzymes and growth factors after radiotherapy and also their possible use as surrogate markers for complications.

  2. 2. Factors associated with healing of periradicular lesions

    Författare :John Danin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Periradicular pathosis; cytokine; IL- Ira; IL-6; TGF-beta1; root canal treatment; endodontic retreatment; root- end surgery; antibiotic; linezolid; refractory periapical lesions.;

    Sammanfattning : Healing of periradicular lesions is a complex process. This thesis addressed some factors of importance to the outcome, namely treatment options and host response in cases of refractory lesions, levels of pro-inflammatory and anti-inflammatory cytokines in the inflammatory lesions and the response of the cytokines to preoperative administration of antibiotics.

  3. 3. Growth factor regulation of the urokinase plasminogen activator (uPA) system in human endometrium, and the significance of uPA receptor activation in endometrial angiogenesis

    Författare :Tove Sandberg; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics; endothelial cell migration; angiogenesis; uPA:PAI-1 complex; uPAR; TGF-beta; PAI-1; EGF; uPA; Growth factor; gynaecology; andrology; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

    Sammanfattning : The purpose of this thesis was to examine the role of growth factors and the urokinase plasminogen activator (uPA) system in human endometrial angiogenesis. Growth factors as well as progesterone increased expression of the main inhibitor of uPA (PAI-1) in primary cultures of endometrial stromal cells. LÄS MER

  4. 4. Regulation of apoptosis in the thyroid epithelium

    Författare :Abeba Demelash; Göteborgs universitet; []
    Nyckelord :Thyroid; Apoptosis; Caspase; Calpain; Hydrogen peroxide; TGF-beta; Staurosporine; Selenium; Cytochrome c;

    Sammanfattning : Apoptosis or programmed cell death allows the multicellular organism to remove cells that are in excess or potentially dangerous. Apoptosis has to be strictly controlled, yet inappropriately activated or suppressed apoptototic may contribute to a variety of diseases, including cancer, autoimmune disorders and neurodegenerative conditions.

  5. 5. Immune regulation within the central nervous system and its role in demyelinating diseases

    Författare :Bao-Guo Xiao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Multiple sclerosis (MS) and its animal model, experimental allergic encephalomyelitis (EAE), are diseases of the central nervous system (CNS) characterized by perivascular mononuclear inflammation and oligodendrocyte loss with demyelination. However, it is still not clear whether the pathology in MS and EAE is due to neuroantigen-specific CD4+ T cell-mediated autoimmune responses and/or bystander myelin damage resulting from an inflammatory response.
