  2. 1. Properties of some chlorinated polycyclic aromatic hydrocarbons with respect to chemical analysis

    Author : Ulrika Nilsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes chemical and biological properties of chloro-added and chloro-substituted PAHs with respect to chemical analysis. The work includes biological testing with Ames assay, study of chemical reactivities in chlorination reactions and retention characteristics on normal phase stationary phases for HPLC, as well as analysis of urban air samples with respect to chlorinated PAHs (Cl-PAHs).

  4. 2. Lysophosphatidic acid : Physiological effects and structure-activity relationships

    Author : Ulrika K. Nilsson; Samuel Svensson; Karin E. Bornfeldt; Linköpings universitet; []
    Keywords : Lysophospholipids pharmacology; physiology; structure-activity relationship; muscle; smooth; drug effects; myometrium; norepinephrine; epinephrine; signal transduction; MEDICINE; MEDICIN;

    Abstract : Lipids havepreviously been considered primarily as building blocks of the cell membrane, but are now also recognized as important cell signaling molecules. Lysophosphatidic acid (LPA) is a glycerophospholipid consisting of a phosphate head group, a linker region, and a lipophilic tail. READ MORE

  5. 3. Effects of sex steroids and tamoxifen on matrix metalloproteinase activity and generation of endostatin in the breast

    Author : Ulrika W. Nilsson; Charlotta Dabrosin; Lena Claesson-Welsh; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; Breast cancer; TGF-β1; Endostatin; Estradiol; Mammary gland; Matrix metalloproteinases; MCF-7; Microdialysis; Nude mice; Tamoxifen; Oncology; Onkologi;

    Abstract : Sex steroids are inevitable in women. However, long-term exposure to sex steroids increases the risk of breast cancer. A complete understanding of sex steroid control of the breast and how it relates to breast cancer risk is still lacking. READ MORE

  6. 4. Formation of Composite Islet Grafts : A novel strategy to promote islet survival and revascularization

    Author : Ulrika Johansson; Peetra Magnusson; Korsgren Olle; Bo Nilsson; Federico Bertuzzi; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Islet of Langerhans; cytokines and cytokinereceptors expression; endothelial cells; mesenchymal stromal cells; transplantation; revascularization; Clinical immunology; Klinisk immunologi; cellforskning; cellforskning;

    Abstract : The islets of Langerhans are small and delicate spheroid organs scattered in the pancreas responsible for insulin production. Transplantation of isolated islets is a beneficial therapy for patients with a severe form of type 1 diabetes. READ MORE

  7. 5. Antibody based plasma protein profiling

    Author : Ulrika Qundos; Jochen M. Schwenk; Peter Nilsson; Mathias Uhlén; Ulrike Korf; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; protein profiling; plasma; antibody; affinity proteomics; biomark- ers; multiplex; assay development;

    Abstract : This thesis is about protein profiling in serum and plasma using antibody suspension bead arrays for the analysis of biobanked samples and in the context of prostate cancer biomarker discovery. The influence of sample preparation methods on antibody based protein profiles were investigated (Papers I-III) and a prostate cancer candidate biomarker identified and verified (Papers III-V).
