Complications after photodynamic therapy.

Effect of Silver Nanoparticles on Improving the Efficacy of 5-Aminolevulinic Acid-Induced Photodynamic Therapy

Introduction: The most important limitation of 5-aminolevulinic acid (5-ALA)-induced photodynamic therapy (PDT) is the efficacy of the cells in converting 5-ALA to protoporphyrin IX. The present study aimed to investigate the effectiveness of silver nanoparticles (AgNPs) with the photosensitivity at the surface plasmon resonance wavelength on 5-ALA-mediated PDT. Material and Methods: First of a...

Half-dose and half-fluence photodynamic therapy for central serous chorioretinopathy

Background: Chronic central serous chorioretinopathy presents a treatment challenge. Photodynamic therapy has been used successfully but with side effects; thus, the authors explored half-dose and half-fluence photodynamic therapy as lower-risk alternatives. Methods: Retrospective medical record review of patients with chronic or recurrent central serous chorioretinopathy who received half-dose...

Photodynamic Inactivation of Endopathogenic Microbiota Using Curcumin- mediated Antimicrobial Photodynamic Therapy

Root canal disinfection is one of the main factors governing success of endodontic therapy. Antimicrobial photodynamic therapy (aPDT) is presented as a promising antimicrobial therapy that can eliminate microbiota present in infected root canal systems. In this study, a series of experiments investigated the effects of aPDT on cell viability and biofilm degradation ability of endopathogenic mic...

Is Photodynamic Therapy Effective in Treatment of Periodontal Diseases? A Review of Literature

Determination of Vascular Endothelial- and Fibroblast-Growth Factor Receptors in a Mouse Fibrosarcoma Tumor Model Following Photodynamic Therapy

The role of angiogenic molecules, like vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF) in tumor angiogenesis was well confirmed. Photodynamic therapy (PDT) action is, to very high degree, based on tumor vasculature damage. Therefore, it seemed to be important to evaluate growth factor receptors after PDT. The extent of receptor expression was studied by immuno-histo...

Photodynamic Therapy: A New Approach to Remove Embryos of the Wistar Rat

Background Photodynamic therapy (PDT) is a promising new cancer treatment strategy which inactivates tumor cells by simultaneoulsy using light and a photosensitizer. The similarity between tumors and newly implanted embryos is notable. Extrauterine pregnancy (EUP) does not have a definite treatment and previous therapeutic options (medical and surgical) have not been effective or suitable. Ther...
