  1. 21. Biomarker Discovery in Cutaneous Malignant Melanoma : A Study Based on Tissue Microarrays and Immunohistochemistry

    Författare :Margrét Agnarsdóttir; Fredrik Ponten; Peter Naredi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibody-based proteomics; automated analysis; biomarker; immunohistochemistry; malignant melanoma; survival; tissue microarray; Tumour biology; Tumörbiologi; Pathology; Patologi; Molecular medicine; Molekylär medicin; Medical Science; Medicinsk vetenskap; Pathology; Patologi;

    Sammanfattning : The incidence of cutaneous malignant melanoma has increased dramatically in Caucasians the last few decades, an increase that is partly explained by altered sun exposure habits. For the individual patient, with a localized disease, the tumor thickness of the excised lesion is the most important prognostic factor. LÄS MER

  3. 22. Treatment with the monoclonal antibody rituximab in Multiple Sclerosis : a study based on an academic clinical trial

    Författare :Pierre de Flon; Anders Svenningsson; Martin Gunnarsson; Katarina Laurell; Sten Fredrikson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Multiple sclerosis; Rituximab; Cytokines; Immunological profile; Neurofilament light; Treatment satisfaction; neurologi; Neurology;

    Sammanfattning : Background: Multiple sclerosis (MS) is a chronic, inflammatory disease, affecting the central nervous system. A growing number of disease modifying treatment alternatives entails a need for an individualised risk-benefit- convenience analysis in the counselling of patients and methods to monitor the treatment effect, including markers for subclinical inflammation.

  4. 23. A quarter century perspective on low back pain : a longitudinal study

    Författare :Carina Bildt Thorbjörnsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Interactions; occupational; non-occupational; interview method; retrospective; reliability; gender; chronic and incident; panel study; non-response;

    Sammanfattning : The focus of this thesis is analyses of associations between occupational and non-occupational conditions on the one hand, and low back pain on the other. Methodological aspects of assessment of information about psychosocial working conditions, as well as of consequences of attrition in longitudinal studies, have also been examined. LÄS MER

  5. 24. On Non Parametric Regression and Panel Unit Root Testing

    Författare :Xijia Liu; Rolf Larsson; Johan Lyhagen; Niklas Ahlgren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : In this thesis, two different issues in econometrics are studied, the estimation of regression coefficients and the non-stationartiy analysis in a panel setting.Regarding the first topic, we study a set of measure of location-based estimators (MLBEs) for the slope parameter in a linear regression model with a single stochastic regressor.

  7. 25. A Study on Structural Cores for Lightweight Steel Sandwiches

    Författare :Samuel Hammarberg; Pär Jonsén; Daniel Berglund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lightweight; Sandwich; Steel; Energy absorption; Homogenization; Finite element; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Lightweight materials and structures are essential building blocks for a future with sustainable transportation and automotive industries. Incorporating lightweight materials and structures in today's vehicles, reduces weight and energy consumption while maintaining, or even improving, necessary mechanical properties and behaviors.
