13. Effects of nanoparticles of hydroxy-aluminum phthalocyanine on markers of liver injury and glucose metabolism in diabetic mice
Photodynamic therapy, by reducing pain and inflammation and promoting the proliferation of healthy cells, can be used to treat recurrent lesions, such as diabetic foot ulcers. Studies using the photosensitizer phthalocyanine, together with the nanostructured copolymeric matrix of Pluronic® and Carbopol® for the treatment of diabetic foot ulcers and leishma

15. Osteoradionecrosis of the jaws: case series treated with adjuvant low-level laser therapy and antimicrobial photodynamic therapy
Abstract Background: Osteoradionecrosis of the jaw (ORNJ) is the most severe and complex sequel of head and neck radiotherapy (RT) because of the bone involved, it may cause pain, paresthesia, foul odor, fistulae with suppuration, need for extra oral communication and pathological fracture. We treated twenty lesions of ORNJ using low-level laser therapy (LL

16. Use of photodynamic inactivation for in vitro reduction of prevalent bacteria in Fournier's Gangrene
ABSTRACT Fournier's Gangrene (FG) is an infectious disease caused by several synergic microbes, with high morbidity and mortality rates; therefore, the search for new less invasive and mutilating treatments, with faster recovery, has been proposed. Surgical intervention, the use of several systemic and topic antibiotics, and hyperbaric oxygen therapy are cur

17. An insight on the role of photosensitizer nanocarriers for Photodynamic Therapy
ABSTRACT Photodynamic therapy (PDT) is a modality of cancer treatment in which tumor cells are destroyed by reactive oxygen species (ROS) produced by photosensitizers following its activation with visible or near infrared light. The PDT success is dependent on different factors namely on the efficiency of the photosensitizer deliver and targeting ability. In

18. Cancer, Photodynamic Therapy and Porphyrin-Type Derivatives
ABSTRACT This review has two parts. The first one gives an approach to interdisciplinary studies against cancer carried out by many scientists using porphyrin-type substrates as photosensitizers in PDT. Intensive studies were performed for almost six decades. The successes really started in 1993 with the first formulation patented under the trade name Photof

19. Photodynamic action of the red laser on Propionibacterium acnes
Abstract: Background: Photodynamic therapy is a therapeutic modality that has consolidated its activity in the photooxidation of organic matter, which arises from the activity of reactive oxygen species. Objective: To evaluate the effect of red laser 660nm with the photosensitizer methylene blue on Propionibacterium acnes in vitro. Method: The experimenta

20. The Effect of Hydrothermal Treatment on the Morphologies and Optical Properties of Upconversion NaYF 4:Ln 3+ Crystals
This work deals with the synthesis and characterization of upconversion NaYF4:Ln3+ crystals. Co-precipitation and hydrothermal methods were used to synthesize NaYF4:Ln3+ crystals. The experimental procedures were modified to obtain crystals in the cubic (α) phase, hexagonal (β) phase or a mixture between cubic and hexagonal (α/β) phases. Reaction tempera

21. Hemoporfin-mediated photodynamic therapy for the treatment of port-wine stain birthmarks in pediatric patients
Abstract: Port-wine stain is a type of common congenital superficial telangiectasia in the dermal layer mostly occurring on the forehead, face, and neck. The affected skin shows abnormal red or purple lesions, which darken and thicken. Nodular changes may develop with advancing age. If untreated, port-wine stains scarcely regress, which can have serious life

22. Effect of photodynamic therapy and non-thermal plasma on root canal filling: analysis of adhesion and sealer penetration
Abstract Objective The aim of this study was to evaluate the effect of photodynamic therapy (PDT) and non-thermal plasma (NTP) on adhesion and sealer penetration in root canals. Material and Methods Sixty single-rooted premolars were used. The teeth were prepared using a crown-down technique. NaOCl and EDTA were used for irrigation and smear layer remova

23. Evaluation of polymeric PLGA nanoparticles conjugated to curcumin for use in aPDT
ABSTRACT Antimicrobial photodynamic therapy (aPDT) involves the association of a photosensitizing agent with a light source with the goal of causing apoptosis or microbial lysing. The use of compounds with natural active principles is gaining prominence throughout the world. Several studies from groups that are linked to the development of innovations in the

24. A new optical intra-tissue fiber irradiation ALA-PDT in the treatment of acne vulgaris in rabbit model: improved safety and tolerability
Abstract Background: Photodynamic therapy with topical aminolevulinic acid (ALA-PDT) has been suggested to be effective in treatment of acne vulgaris. However, adverse events occur during and after treatment. Objectives: To compare the efficacy and tolerability of optical intra-tissue fiber irradiation (OFI) ALA-PDT versus traditional ALA-PDT in treatment
