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

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

    Abstract : 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. READ MORE

  4. 2. A biophysical study of nucleic acid interactions with analogues and drugs

    Author : Ulrica Sehlstedt; Donald M Crothers; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nucleic acids; binding modes; polarised light spectroscopy; linear dichroism; NMR; triple helix; base-pair breathing dynamics; DAPI; porphyrins; quinoxaline derivatives; Biophysics; Biofysik; Biophysics; biofysik;

    Abstract : work presented in this thesis concerns studies on the physicochemical nature of interactions between nucleic acids and small ligands. The outcome of such studies can yield insights at a molecular level into the physiological mechanisms of action of biologically active nucleic-acid binding molecules. READ MORE

  5. 3. Porphyrins and phototherapy of oral bacteria

    Author : Nadja Bjurshammar; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In the mid-1990s researchers became interesting in blue light-based therapies using light-emitting diodes (LED) light. Blue light therapy has been successfully used in treatment of acne, as well as shown wound healing effects. It has also shown significant antibacterial effects, especially on black-pigmented bacteria. READ MORE

  6. 4. Structural and physicochemical studies on metal and porphyrin binding by the Bacillus subtilis ferrochelatase

    Author : Mattias Hansson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal specificity; metal binding; porphyrin metallation; time resolved crystallography; fluorescence quenching; X-ray structure; inclusion bodies; Bacillus subtilis; heme biosynthesis; ferrochelatase; hemH;

    Abstract : The enzyme ferrochelatase (EC 4.99.1.1) is the terminal enzyme in the biosynthetic pathway of heme b and catalyzes the insertion of Fe(II) into protoporphyrin IX. READ MORE

  7. 5. Life of Excitons in Artificial Photosynthetic Antennas

    Author : Johan Andersson; Kemisk fysik; []
