  1. 6. Skin phototesting using a divergent ultraviolet B beam : development and evaluation on a normal material

    Författare :Michail Ilias; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The phototesting method proposed provokes the skin by means of a divergent UVB beam. The beam divergence is induced by an optical plano-concave !ens placed at the opening of the light guide which directs the light from the UV lamp to the skin. LÄS MER

  3. 7. Molecular Genetic and DNA Methylation Profiling of Chronic Lymphocytic Leukaemia : A Focus on Divergent Prognostic Subgroups and Subsets

    Författare :Nicola Cahill; Richard Rosenquist; Larry Mansouri; Fergus Ryan; Denis Alexander; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA methylation; Chronic lymphocytic leukemia; SNP; array; IGHV3-21; IGHV4-34; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Genetics; Genetik; Medical Genetics; Medicinsk genetik; Molecular Biology; Molekylärbiologi; Molekylär genetik; Molecular Genetics; Oncology; Onkologi;

    Sammanfattning : Advancements in prognostication have improved the subdivision of chronic lymphocytic leukaemia (CLL) into diverse prognostic subgroups. In CLL, IGHV unmutated and IGHV3-21 genes are associated with a poor-prognosis, conversely, IGHV mutated genes with a favourable outcome. LÄS MER

  5. 9. Towards a broader use of phototesting : in research, clinical practice and skin cancer prevention

    Författare :Magnus Falk; Chris Anderson; Karin Wårdell; Olle Lärkö; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phototesting; divergent beam; skin cancer prevention; self-reading; minimal erythema dose; sun protection behaviour; Dermatology and venerology; Dermatologi och venerologi;

    Sammanfattning : In western societies, skin cancer incidence has increased dramatically over recent decades, due predominantly to increased sun exposure habits. Ultraviolet (UV) light exposure and individual light sensitivity of the skin constitute two important factors affecting the risk for skin cancer development. LÄS MER

  7. 10. Evolution of Spur Length in a Moth-pollinated Orchid

    Författare :Elin Boberg; Jon Ågren; W. Scott Armbruster; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Platanthera bifolia; floral evolution; natural selection; pollination; spur length; population differentiation; divergent selection; disruptive selection; reproductive isolation; Biology; Biologi; Ecological Botany; Ekologisk botanik;

    Sammanfattning : There is considerable evidence that pollinator shifts can explain many differences in flower morphology between closely related plant species, but the extent to which pollinator shifts can explain the maintenance of among-population variation in floral traits within species is poorly known. In this thesis, I combined comparative and experimental approaches to examine the evolution of floral traits in the moth-pollinated orchid Platanthera bifolia. LÄS MER
