Time-multiplexed two-channel capacitive radiofrequency hyperthermia with nanoparticle mediation.
BACKGROUND Capacitive radiofrequency (RF) hyperthermia suffers from excessive temperature rise near the electrodes and poorly localized heat transfer to the deep-seated tumor region even though it is known to have potential to cure ill-conditioned tumors. To better localize heat transfer to the deep-seated target region in which electrical conductivity is elevated by nanoparticle mediation, two...
متن کاملGelatin microcapsules for enhanced microwave tumor hyperthermia.
Local and rapid heating by microwave (MW) irradiation is important in the clinical treatment of tumors using hyperthermia. We report here a new thermo-seed technique for the highly efficient MW irradiation ablation of tumors in vivo based on gelatin microcapsules. We achieved 100% tumor elimination in a mouse model at an ultralow power of 1.8 W without any side-effects. The results of MTT assay...
متن کاملCapacitive Hyperthermia as an Alternative to Brachytherapy in Treatment of Human Prostate Cancer Cell
Introduction: The aim of this study was the evaluation of induced DNA damages of human prostate cancer cells, DU-145, treated with a combination of radiofrequency capacitive hyperthermia (HT) and teletherapy (EBRT) compared to a combination of teletherapy with high dose rate brachytherapy (BR). Materials and Methods: DU-145 cells were cultured as spheroids ...
متن کاملAn Overview of Microwave Bandpass Filters with Capacitive Coupled Resonators
This paper presents a summary of several bandpass filters all consisting of resonators coupled only by capacitive coupling. The basic filter’s configuration with asymmetric inductors is explained in detail as well as its modifications with asymmetric capacitors. The filter’s design process is undemanding due to the filter’s simple configuration, while its compact size makes it suitable for inte...
متن کاملMicrowave Cavity with Controllable Temperature for In Vitro Hyperthermia Investigations
Hyperthermia is a form of cancer treatment in which affected human tissue is exposed to >40°C temperature. In this paper, our goal is to assess the efficacy of fullerene agents to reduce heating time for cancer treatment. Such agents can accelerate heating of cancer cells and improve hyperthermia treatment efficacy. Typically, in vitro testing involves cancer cell culturing, heating cell cultur...
