  1. 16. Ultraviolet light, autoimmune disorders and the etiology of malignant lymphomas

    Författare :Karin Ekström Smedby; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Non-Hodgkin lymphoma; Hodgkin lymphoma; ultraviolet light; autoimmune disorders; rheumatoid arthritis; celiac disease; risk factors; cohort; case-control; epidemiology;

    Sammanfattning : Malignant lymphomas constitute a clinically and morphologically diverse group of malignancies that may also differ etiologically. The incidence of the most common non-Hodgkin lymphomas (NHL) has increased dramatically worldwide during the past decades. LÄS MER

  3. 17. Single exposure phototesting and assessment of pigmented skin lesions : quantitative methods in terms of blood perfusion estimates

    Författare :Michail A. Ilias; Karin Wårdell; Stephan El Gammal; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This thesis concerns the development of quantitative phototesting for the investigation of individual skin sensitivity to ultraviolet (UV) radiation, and the assessment of pigmented skin lesions (PSL) in terms of blood perfusion estimates. In both cases, laser Doppler perfusion imaging (LDPI) was used to quantify the perfusion. LÄS MER

  4. 18. Exposure to motor exhaust in the occupational and general environment in Stockholm county

    Författare :Marie Lewné; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Exposure measurement; NO2; Particles; EC; diesel exhaust;

    Sammanfattning : In recent years, health hazards associated with air pollution from motor exhaust have received increasing attention. Lung cancer and heart disease have been linked to air pollution exposure. However, the knowledge concerning exposure levels, is insufficient, but is essential for risk assessment. LÄS MER

  5. 19. Imaging of nucleocytoplasmic transcription factor dynamics in yeast

    Författare :Kristofer Bodvard; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transcription factor; single-cell; yeast; image analysis; Saccharomyces cerevisiae; light stress; Fluorescence microscopy; signalling;

    Sammanfattning : Fluorescence microscopy has proven to be an invaluable tool in identifying and understanding cell signalling, intracellular spatial and temporal dynamics, and cell-to-cell variability. This thesis focuses on imaging of nucleocytoplasmic transcription factor dynamics at the single cell level in yeast. LÄS MER

  7. 20. Influence of exposure patterns and oxidation in UVR-induced cataract

    Författare :Marcelo Ayala; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cataract; ultraviolet radiation; lens; in vivo; rats; oxidative process; time;

    Sammanfattning : Background: Ultraviolet radiation (UVR) is one among a number of possible factors that may lead to the development of cataract. Whereas induction of cataract as the result of onetime exposure to UVR has been studied extensively, the data on lens damage resulting from repeated exposures to UVR are scarce. LÄS MER
