Quantitative Ultrasound Characterization of Tumor Cell Death: Ultrasound-Stimulated Microbubbles for Radiation Enhancement

The aim of this study was to assess the efficacy of quantitative ultrasound imaging in characterizing cancer cell death caused by enhanced radiation treatments. This investigation focused on developing this ultrasound modality as an imaging-based non-invasive method that can be used to monitor therapeutic ultrasound and radiation effects. High-frequency (25 MHz) ultrasound was used to image tum...

Cellular characterization of ultrasound-stimulated microbubble radiation enhancement in a prostate cancer xenograft model

Tumor radiation resistance poses a major obstacle in achieving an optimal outcome in radiation therapy. In the current study, we characterize a novel therapeutic approach that combines ultrasound-driven microbubbles with radiation to increase treatment responses in a prostate cancer xenograft model in mice. Tumor response to ultrasound-driven microbubbles and radiation was assessed 24 hours aft...

Effect of 3 MHz ultrasound radiation on retinoblastoma cell line

Ultrasound hyperthermia is a new way to treat cancerous tumors. Retinoblastoma is one of the most common malignant ocular tumors in children. Since hyperthermia is an effective treatment for cancer cells, the effect of hyperthermia on retinoblastoma cells was investigated in this study. The purpose of this study was to determine the effect of duration of 3 MHz ultrasound hyperthermia on Y79 cel...

Ultrasound-stimulated microbubble enhancement of radiation treatments: endothelial cell function and mechanism

Endothelial cell death caused by novel microbubble-enhanced ultrasound cancer therapy leads to secondary tumour cell death. In order to characterize and optimize these treatments, the molecular mechanisms resulting from the interaction with endothelial cells were investigated here. Endothelial cells (HUVEC) were treated with ultrasound-stimulated microbubbles (US/MB), radiation (XRT), or a comb...
