1. Evaluation of meso-substituted cationic corroles as potential antibacterial agents
ABSTRACT Cationic derivatives of 5,10,15-tris[4-(pyridin-4-ylsulphanyl)-2,3,5,6-tetrafluorophenyl]-corrolategallium(III)pyridine and 5,10,15-tris[4-(pyridin-2-ylsulfanyl)-2,3,5,6-tetrafluorophenyl]-correlategallium(III)pyridine were synthesized and their photosensitizing properties against the naturally bioluminescent Gram-negative bacterium Allivibrio fisch

2. Avaliação da eficácia da terapia fotodinâmica como adjunto ao tratamento periodontal de pacientes com periodontite agressiva / Evaluation of the photodynamic therapy efficacy in the treatment of patients with agressive periodontitis
A periodontite agressiva é um processo inflamatório de origem bacteriana mediado pelo sistema imunológico do hospedeiro e é provavelmente a forma mais grave de doença periodontal, apresentando destruição das estruturas tanto de proteção quanto de suporte dentário, num período relativamente rápido, normalmente levando a perda prematura dos element

3. Efeito da terapia antimicrobiana fotodinâmica no tratamento da periodontite experimental. Estudo bioquímico e microbiológico em cães / The effect of antimicrobial photodynamic therapy in the treatment of experimental periodontitis. A biochemical and microbiological study in dogs
The purpose of this study was to evaluate the effect of a single application of antimicrobial photodynamic therapy (aPDT) on microbiological profile and cytokine pattern in dogs. Periodontal disease was induced by placing 3.0 silk ligatures around the mandibular pre-molars bilaterally during 8 weeks. The dogs were randomly treated with aPDT using a dye/laser

4. Light-dependent activity of the antitumor antibiotics ravidomycin and desacetylravidomycin.
The antitumor antibiotics ravidomycin and desacetylravidomycin were studied by the biochemical lambda prophage induction assay. In this assay, induction of the enzyme beta-galactosidase is measured as a specific indication of the ability of an agent to directly or indirectly damage DNA. Induction was observed only when these two antibiotics were irradiated w

5. Strand specificity of mutagenic bypass replication of DNA containing psoralen monoadducts in a human cell extract.
Psoralens are mutagenic compounds of vegetable origin that are used as photosensitizing agents in the treatment of various skin diseases, blood cell cancer, and autoimmune disorders. To study the mechanism of mutagenicity of psoralens in humans, we examined the efficiency and fidelity of simian virus 40 origin-dependent replication in a human cell extract of

6. Uroporphyrin I Stimulation of Collagen Biosynthesis in Human Skin Fibroblasts: A UNIQUE DARK EFFECT OF PORPHYRIN
Porphyria cutanea tarda and erythropoietic porphyria are disorders of heme synthesis that originate in the liver and bone marrow, respectively. Each is characterized by increased accumulation of uroporphyrin, I, by cutaneous photosensitivity, and in some patients by indurated plaques and scarring that resemble scleroderma. These scleroderma-like lesions occu
