  1. 16. Electron Microscopy in Diagnostic Pathology with Reference to Mesenchymal Tumors

    Författare :Birgitta Carlén; Tumörmikromiljö; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; synovial sarcoma; Kaposi´s sarcoma; epithelioid sarcoma; parachordoma; alveolar soft part sarcoma; small cell malignant tumors of childhood and adolescence; cultured cells; surgical specimens; Transmission electron microscopy; fine needle aspiration; General pathology; pathological anatomy; Patologi allmän ; patologisk anatomi;

    Sammanfattning : The experience acquired over a period of 15 years of diagnostic electron microscopy of fine needle aspirates and surgical specimens constitutes the base for this thesis. Some of the tumors analyzed represent rare soft tissue tumors, and consequently not very often ultrastructurally described. LÄS MER

  3. 17. Studies on Tissue Factor with Focus on Cell Signaling and Cancer

    Författare :Oskar Eriksson; Agneta Siegbahn; Lina Badimon; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue Factor; blood coagulation; cell signaling; protease; mass spectrometry; immunohistochemistry; colorectal cancer; apoptosis; Eph receptor; Klinisk kemi; Clinical Chemistry; Molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : This thesis have explored the functions of the protein Tissue Factor (TF), which together with its ligand coagulation factor VII/VIIa (FVII/FVIIa) forms a proteolytic complex that functions in initiation of blood coagulation and activation of cell signaling.In paper I, the mechanisms behind the observation that TF/FVIIa signaling protects cells from apoptosis were further investigated.

  4. 18. Immunogenetics and treatment of experimental autoimmune encephalomyelitis

    Författare :Robert Weissert; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Multiple sclerosis; experimental autoimmune encephalomyelitis; major histocompatibility complex; myelin; myelin oligodendrocyte glycoprotein; T cell receptor;

    Sammanfattning : Experimental autoimmune encephalomyelities (EAE) is a model of multiple sclerosis (MS). This experimental central nervous system (CNS) disease can be induced in rats by immunization with components of the CNS myelin sheath. LÄS MER

  5. 19. Capillary electrophoresis methods for the separation of the basic compound lidocaine and its metabolites

    Författare :Magnus S. Andersson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Sammanfattning : For the separation of the basic compound lidocaine and its metabolites a variety of capillary electrophoresis (CE) methods have been developed. This includes capillary zone electrophoresis (CZE), micellar electrokinetic chromatography (MEKC) and nonaqueous CE separations. The parameters affecting the separations were investigated and optimized. LÄS MER

  7. 20. Controlled Trapping in Laser Wakefield Accelerators

    Författare :Martin Hansson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser; Wakefield; Acceleration; Trapping; Fysicumarkivet A:2016:Hansson;

    Sammanfattning : Experimental studies of laser-driven acceleration of charged particles, in particular electrons and protons, are described in this dissertation. Tightly focused femtosecond laser pulses with intensities exceeding 1018 W/cm2 were used to accelerate charged particles to high energies over distances of a few millimeters. LÄS MER
