    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; serology; Immunology; mykologi; bakteriologi; virologi; Mikrobiologi; mycology; Complement; Complement C2 deficiency; Infectious diseases; Atherosclerosis; SLE; Autoantibodies; GM allotypes; Immunodeficiency state; Medicine human and vertebrates ; Medicin människa och djur ; Microbiology; virology; bacteriology; Immunologi; serologi; Infections; Infektioner;

    Sammanfattning : The complement system is a part of the innate immunity and is essential in the defence against microorganisms. Hereditary C2 deficiency (C2D) is one of the most common complement deficiency states with an estimated prevalence of 1:20,000 in persons of Western descent. LÄS MER

  3. 2. Time Resolved Laser Spectroscopy of Rydberg States in Group IIIA and IIIA Elements

    Författare :Göran Jönsson; Fysiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this work radiative properties of neutral elements with one or two electrons outside closed subshells have been investigated. Using laser techniques in connection with atomic beams selective excitation of Rydberg states was performed. Most of the studied states were populated with two-step excitation. LÄS MER

  4. 3. Genetic characterization of malignant melanoma and breast cancer

    Författare :Göran B Jönsson; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; microarray; inherited breast cancer; Melanoma; linkage analysis; cancer; Cytologi; cancerology; onkologi;

    Sammanfattning : Malignant melanoma and breast cancer are common malignant diseases characterized by considerable heterogeneity with respect to genetics, histopathology, biology and clinical course. In breast cancer, two major susceptibility genes have been identified, BRCA1 and BRCA2, which account for a significant proportion of high-risk breast cancer families. LÄS MER

  5. 4. Thermomechanical Processing of Nickel-Base Alloy 825

    Författare :Munir Al-Saadi; Pär Jönsson; Christopher Hulme-Smith; Göran Engberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 825; Cast and wrought structures; Hot compression test; Microstructural evaluation; Modelling; Yield strength; Strengthening mechanisms; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Alloy 825 material was studied using a Gleeble-3800 thermosimulatorby performing single-hot compression experiments.Optical microscopy and electron backscatter diffraction wereutilized to characterize the microstructure. Dynamicrecrystallization is not considerable in the as-cast alloy anddislocation recovery is deemed to be dominant. LÄS MER

  7. 5. Diagnostic Evaluation of Schizophrenia for Genetic Studies

    Författare :Birgit Ekholm; Rolf Adolfsson; Erik Jönsson; Göran Sedvall; Leif Lindström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Psychiatry; Schizophrenia; Diagnostic evaluation; Molecular genetic studies; Linkage; Association; Psykiatri; Psychiatry; Psykiatri; psykiatri; Psychiatry;

    Sammanfattning : Schizophrenia is one of the most severe mental disorders. Heredity is accepted as a major causative factor. To find molecular mechanisms behind schizophrenia, patient materials with reliable and valid diagnoses must be identified. LÄS MER
