A Role For Reactive Oxygen Species In Photodynamic Therapy

A ROLE FOR REACTIVE OXYGEN SPECIES IN PHOTODYNAMIC THERAPYbyMICHAEL PRICEDecember 2012Advisor:David Kessel, Ph.D.Major:Cancer BiologyDegree:Doctor of PhilosophyPhotodynamic therapy (PDT) is based on the ability of certain photosensitizingagents to selectively localize in neoplastic cells and their vasculature. Subsequentirradiation at a wavele...

In vitro study of reactive oxygen species production during photodynamic therapy in ultrasound-pretreated cancer cells.

Several recent studies bring evidence of cell death enhancement in photodynamic compound loaded cells by ultrasonic treatment. There are a number of hypotheses suggesting the mechanism of the harmful ultrasonic effect. One of them considers a process in the activation of photosensitizers by ultrasonic energy. Because the basis of the photodynamic damaging effect on cells consists in the product...

Effect of 5-aminolevulinic acid-based photodynamic therapy via reactive oxygen species in human cholangiocarcinoma cells

Cancer cells have been reported to exhibit an enhanced capacity for protoporphyrin IX (PpIX) synthesis facilitated by the administration of 5-aminolevulinic acid (ALA). We investigated the effect of ALA-based photodynamic therapy (PDT) on human cholangiocarcinoma cells (HuCC-T1). Since protoporphyrin IX (PpIX), a metabolite of ALA, can produce reactive oxygen species (ROS) under irradiation and...

Gold nanoparticles/ZnO nanorods hybrids for enhanced reactive oxygen species generation and photodynamic therapy

Gold nanoparticles (Au NPs)@ZnO nanorods (NRs) hybrids, with various molar ratios of ZnO:Au, were developed to enhance generation of reactive oxygen species (ROS) for further application in photodynamic therapy (PDT). By introducing the metal/semiconductor heterostructure interface between Au NPs and ZnO NRs, the electron transfer was modulated under UV irradiation, which dramatically suppresse...

O 22: Reactive Oxygen Species and Epilepsy

Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...
