Commonly used irrigants do not always eradicate the entire microbial flora in infected root canals. Therefore, several other strategies, such as photodynamic therapy (PDT) have been developed. Photoactivated disinfection is based on the interaction of a photosensitive antibacterial agent and a light source. It uses a nontoxic dye named photosensitizer (PS) and low-intensity visible light. In ox...

Photodynamic therapy (PDT) is an innovative and perspective antineoplastic therapy. Tetra-α-(4-carboxyphenoxy) phthalocyanine zinc (TαPcZn)-mediated PDT (TαPcZn-PDT) has shown antitumor activity in some tumor cells, but the manner which caspase-1 involved regulation of apoptosis pyroptosis TαPcZn-PDT-treated breast cancer MCF-7 cells unclear. Therefore, effects TαPcZn-PDT on cytotoxicity, cell ...

Treatment of childhood rhabdomyosarcoma is limited by recurrent disease and the development of multidrug resistance. Therefore, novel treatment options are desirable. Photodynamic therapy (PDT) using the photodynamic agent hypericin is proposed as an alternative approach for intraoperative visualization and treatment of this disease. The aim of this study was to investigate in vitro effects of ...

Oral lichen planus (OLP) is a relatively common chronic immunologic mucocutaneous disorder. Although there are many presenting treatments, some of them proved its failure. Recently, the use of photodynamic therapy (PDT) has been expanding due to its numerous advantages, as it is safe, convenient, and non-invasive and has toxic effect towards selective tissues. This article provides comprehensiv...

Abstract Photodynamic therapy (PDT) for hypoxic tumors has attracted wide attention owing to its noninvasiveness, easy maneuverability, and instantaneity. However, hypoxia in penetration depth of conventional ultraviolet light greatly weakened performance. To solve these problems, under NIR-II irradiation, squaric acid nanoparticles (SQ NPs) with superior reactive oxygen, especially, hydroxyl r...

PURPOSE To evaluate the accuracy of fluorescence bronchoscopy by precise histological analysis of the photodynamic therapy (PDT) treated lesions. METHODS A retrospective study was conducted on thirteen patients (16 lesions) with centrally located early lung cancer (CLELC) had been undergone photodynamic therapy and had been followed up by fluorescence bronchoscopy. Fluorescence bronchoscopy w...

PURPOSE To study the long-term effects of photodynamic therapy (PDT), using liposomal benzoporphyrin derivative (BPD) or Verteporfin, on experimental choroidal neovascularization (CNV) and on normal retina and choroid (with no CNV) in the cynomolgus monkey eye. METHODS Photodynamic therapy was performed in 8 cynomolgus monkey eyes with experimental CNV induced by laser injury. The effect of P...

A successful photodynamic therapy (PDT) requires a specific photosensitizer, oxygen and light of a specific wavelength and power. Today photodynamic therapy (PDT) is administered to patients with light-emitting diode (LED) panels. These panels deliver a non-uniform light distribution on the human body parts, as the complex human anatomy is not a flat surface (head vertex, hand, shoulder, etc.)....

We report the favorable anatomic and functional outcome of photodynamic therapy with verteporfin in a case of chronic central serous chorioretinopathy complicated with choroidal neovascularization (CNV). This 37-year-old Chinese male with bilateral chronic central serous chorioretinopathy presented with central scotoma, reduced vision and metamorphopsia in his right eye. Fluorescein angiography...
