  1. 1. Colour Correction of Underwater Images Using Spectral Data

    Författare :Julia Åhlén; Ewert Bengtsson; Jussi Parkkinen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Colour; Correction; Attenuation; Coefficient; Underwater; Bildanalys; Image analysis; Bildanalys; Computer science;

    Sammanfattning : For marine sciences sometimes there is a need to perform underwater photography. Optical properties of light cause severe quality problems for underwater photography. Light of different energies is absorbed at highly different rates under water causing significant bluishness of the images. LÄS MER

  3. 2. Markers for clinical outcome and therapy response in soft tissue sarcomas

    Författare :Jan Åhlen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Soft-tissue sarcomas (STSs) constitute a heterogeneous group of rare but aggressive tumors that originate from mesenchymal cells in almost any part of the body. Gastrointestinal stromal tumor (GIST), located in the gastrointestinal tract, is the most common type of STS. LÄS MER

  5. 4. Collagen-binding integrin α2β1 activity in vivo and in vitro : Effects of platelet-derived growth factor-BB

    Författare :Karina Åhlén; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Integrin α2β1; PDGF-BB; fibroblast; interstitial fluid pressure; cytoskeletal interaction; phosphatidylinositol 3-kinase; [Ca2 ]i; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Sammanfattning : The expression of integrins by two cell clones from a rat colon carcinoma was investigated. Cloned cells that gave rise to regressive tumors, but not cells that gave rise to progressive, lethal, tumors, adhered to interstitial collagens through the integrin α2β1, although both cell types expressed it.
