  1. 11. Photodynamic therapy and laser-based diagnostic studies of malignant tumours

    Författare :Ingrid Wang; Medicinskt lasercentrum; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protoporphyrin IX PpIX ; delta -aminolevulinic acid ALA ; photosensitizer; basal cell carcinoma BCC ; Photodynamic therapy PDT ; laser-induced fluorescence LIF ; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

    Sammanfattning : Two non-thermal regimens of light interaction with biological tissue, that are in a natural way connected, are discussed in the present thesis. These are photodynamic therapy (PDT) for the treatment of malignant tumours and laser-induced fluorescence (LIF) for tissue characterization. LÄS MER

  3. 12. Towards Undistorted Fluorescence for Tissue Diagnostics and Therapy Monitoring

    Författare :Haiyan Xie; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; upconversion; upconverting nanoparticles; fluorescence-guided-surgery; fluorescence diagnostics; photodynamic therapy; multi-spectral imaging; spectroscopy; biomedical optics; fluorescence; Fysicumarkivet A:2014:Xie;

    Sammanfattning : Fluorescence techniques for applications in tissue diagnostics and therapy monitoring were investigated and developed in the work presented in this thesis. The aim was to develop fluorescence diagnostics for the detection of malignant tumors and better delimitation of the tumor margins, using the enhanced contrast in fluorescence between tumor and surrounding healthy tissue.

  4. 13. Photdynamic therapy for treatment of Acne Vulgaris in clinical studies; dose response and mode of action

    Författare :Camilla Hörfelt; Göteborgs universitet; []
    Nyckelord :Photodynamic therapy; Acne Vulgaris; Delta-aminolaevulinic acid; Methyl-aminolaevulinic acid; Porphyrins; Propionibacterium acnes; Fluorescence imaging;

    Sammanfattning : This thesis deals with the use of photodynamic therapy (PDT) for treatment of Acne Vulgaris. Acne Vulgaris is one of the most common skin disorders. Conventional treatments target the pathogenic factors and include a variety of topical and oral medications such as antibiotics. LÄS MER
