A three-dimensional computational model is presented for studying the efficacy of high-intensity focused ultrasound (HIFU) procedures targeted near large blood vessels. The analysis applies to procedures performed at intensities below the threshold for cavitation, boiling and highly nonlinear propagation, but high enough to increase tissue temperature a few degrees per second. The model is base...

Developments in the technology applied to the field of minimally invasive surgery have led to the exploration of high-intensity focused ultrasound (HIFU) for the treatment of localized prostate cancer. Extensive research and continuous evolution have resulted in two commercially available HIFU devices: the Ablatherm and the Sonablate500. These devices are conceptually the same; however, specifi...

Objective: The purpose of this study was to compare the effectiveness of compassion focused (CFT) and acceptance commitment (ACT) combined therapy with cognitive-behavioral therapy (CBT), on psychological well-being in women with type 2 diabetes (T2DM). Materials and Methods: This is quasi-experimental. This study consists of three groups (two experimental and one control groups) and three sta...

A small proportion of hepatocellular carcinoma (HCC) patients are suitable for surgical resections and various minimally invasive procedures have been introduced as alternatives to surgical resections. However, the relative efficacy of minimally invasive procedures remains to be studied in the current literature. Several popular minimally invasive procedures (monotherapy or combined therapies) ...

PURPOSE To determine if pulsed-high intensity focused ultrasound (HIFU) could effectively serve as a source of hyperthermia with thermosensitive liposomes to enhance delivery and efficacy of doxorubicin in tumors. EXPERIMENTAL DESIGN Comparisons in vitro and in vivo were carried out between non-thermosensitive liposomes (NTSL) and low temperature-sensitive liposomes (LTSL). Liposomes were inc...

The purpose of this study was to verify the efficacy and safety of high intensity focused ultrasound therapy (HIFU) combined with S-1 in the treatment of metastatic pancreatic cancer after failure of gemcitabine (GEM). In total, 120 patients with GEM-refractory PC who received HIFU and S-1 between Aug 2012 and December 2014 were randomly assigned to 2 groups. The patients in group A (n = 61) re...
