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

    Author : Ingrid Wang; Medicinskt lasercentrum; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Exploring nanosystems for biomedical applications focusing on photodynamic therapy and drug delivery

    Author : Vladimir Kirejev; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photodynamic therapy; PDT enhancement; Nitric oxide; NO-based PDT; Targeted drug delivery; Galectin-3; mTHPP; Cyclodextrin; CD-mTHPP conjugate; PpIX AuNP combination; Two-photon microscopy; FLIM; Cell phototoxicity; Ex vivo skin;

    Abstract : The increasing incidences of cancer and related deaths call for the development of new and improved treatment modalities. Photodynamic therapy (PDT) today is an alternative to conventional treatments, but has limitations. This thesis explores different nanosystems with aim to improve PDT focusing on spectroscopic and ex vivo studies. READ MORE

  5. 3. Photodynamic therapy in the head and neck

    Author : Mathias von Beckerath; Claes Möller; Göran Laurell; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Photo Dynamic Therapy; Cancer; Skin; Larynx; 5-ALA; UVradiation; sarcoma; squamous cell carcinoma; porfimer sodium; temoporfin; voice; Kirurgi; Surgery;

    Abstract : Photodynamic therapy, PDT, is a method to diagnose and treat cancer. In PDT a sensitizer is administered to the patient and this sensitizer is accumulated in tumors. If the sensitizer-containing tumor is subjected to a laser of a specific wavelength the tumor is fluorescing allowing diagnostics. READ MORE

  6. 4. Photodynamic Therapy utilizing Interstitial Light Delivery Combined with Spectroscopic Methods

    Author : Marcelo Soto Thompson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; onkologi; Cytologi; cancerology; oncology; Cytology; fiber optics; dosimetry; spectroscopy; tissue optics; laser-induced fluorescence; medical laser systems; Laserteknik; cancer; photodynamic therapy; interstitial; Laser technology; Fysicumarkivet A:2004:Soto Thompson;

    Abstract : Since cancer continues to plague humanity there is large need for development of modalities for both diagnosis and therapy. Most of the currently available methods suffer from serious disadvantages. The treatments, e.g. READ MORE

  7. 5. Methods, Instrumentation and Mechanisms for Optical Characterization of Tissue and Treatment of Malignant Tumours

    Author : Sara Pålsson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; temperature; perfusion; PDT; photodynamic therapy; mechanisms; tissue characterization; instrumentation; optical biopsy; fluorescence spectroscopy; spectroscopy techniques; Raman spectroscopy; interstitial photodynamic therapy; photodynamic threshold dose; Atomic and molecular physics; Atom- och molekylärfysik;

    Abstract : In this thesis, different optical methods utilising visible light for characterization of tissue have been developed and evaluated. The feasibility of many of these methods has been demonstrated in the laboratory or in animal experiments. READ MORE
