Photofrin II as an efficient radiosensitizing agent in an experimental tumor [PDF]

open access: yes, 2001
Background and Objective: The use of ionizing irradiation as radiation therapy (RT) for tumor treatment represents a well-established method. The use of photodynamic therapy (PDT), especially with Photofrin II, for tumor treatment is also known. Chemical

Recent Updates on Local Ablative Therapy Combined with Chemotherapy for Extrahepatic Cholangiocarcinoma: Photodynamic Therapy and Radiofrequency Ablation

open access: yesCurrent Oncology, 2023
Although chemotherapy constitutes of the first-line standard therapy for unresectable extrahepatic cholangiocarcinoma, the treatment outcomes are unsatisfactory. In recent years, local ablative therapy, which is delivered to the cholangiocarcinoma lesion

Photodynamic therapy of cholangiocarcinoma [PDF]

open access: yesHPB, 2008
Photodynamic therapy (PDT) is a local photochemical tumor treatment that consists of a photosensitizing agent in combination with laser irradiation of a distinct wavelength. In some case reports and small non-randomized pilot studies, PDT has proved feasible in patients with hilar bile duct cancer. Those studies showed an astonishing long survival time

From Exciton Dynamics to Cell Fate: A Carbon Dot Based NIR Photocatalytic Platform for Pyroptosis via Self‐Trapped Excitons

open access: yesAdvanced Functional Materials, EarlyView.
A facile and effective method to boost NIR light induced photocatalysis based on nontoxic NIR emissive carbon dots (nir‐CDs) via Self‐trapped excitons, showing that both O2− • and •OH can be generated from nir‐CDs under NIR laser irradiation. Abstract Near‐infrared (NIR) light‐triggered photocatalytic therapy remains a critical challenge in efficient ...

Photodynamic therapy in brain cancer: mechanisms, clinical and preclinical studies and therapeutic challenges

open access: yesFrontiers in Chemistry, 2023
Cancer is a main cause of death and preferred methods of therapy depend on the type of tumor and its location. Gliomas are the most common primary intracranial tumor, accounting for 81% of malignant brain tumors.

Photodynamic Therapy in Gastroenterology

open access: yesJournal of Gastrointestinal Cancer, 2013
Photodynamic therapy (PDT) is a minimally invasive and promising new modality to combat cancer. Upon illumination and in the presence of oxygen, the tissue-localized nontoxic sensitizer generates cytotoxic reactive oxygen species, and as a result, the selective destruction of a targeted tumor may be achieved.

DENTA: A Dual Enzymatic Nanoagent for Self‐Activating Tooth Whitening and Biofilm Disruption

open access: yesAdvanced Functional Materials, EarlyView.
The nanoapatite with dual enzymes (DENTA) accumulates in dentinal tubules, reducing hypersensitivity caused by dental nerve exposure and facilitating continuous ROS generation through salivary glucose for effective, long‐term whitening. The dentin structures remain non‐destructive due to the low concentration of ROS, demonstrating excellent cell ...
