High-intensity focused ultrasound (HIFU) is a treatment option for low- and intermediate-risk prostate cancer and more recently has been used as salvage therapy after failed radiation therapy. We present a case of local recurrence with biochemical failure after radical prostatectomy and salvage external beam radiation therapy with salvage HIFU without biochemical recurrence at 20 months.

The goal was to test the effects of various combinations of pulse widths (PW) and duty cycles (DC) on high-intensity focused ultrasound (HIFU)-induced sonothrombolysis efficacy using an in vitro flow model. An ExAblate™ 4000 HIFU headsystem (InSightec, Inc., Israel) was used. Artificial blood clots were placed into test tubes inside a human calvarium and exposed to pulsatile flow. Four differen...

Several ultrasound-based imaging modalities have been proposed for image guidance and monitoring of High-Intensity Focused Ultrasound (HIFU) surgery. However, accurate localization and characterization of the effective region of treatment (thermal lesion) remain the obstacles in the clinical implementation of HIFU ablation. Harmonic motion imaging for focused ultrasound (HMIFU) is a novel HIFU ...

this study investigated the relative effects of deductive and inductive form-focused instruction (ffi) on the acquisition of 4 non-generic definite article uses(cultural, situational, structural, and textual) as assessed by explicit and implicit outcome measures. the tests utilized to assess efl learners' acquisition of definite article uses were timed and untimed grammaticality judgment tests....

This study investigated the effects of prompts as corrective feedback strategy on teaching /θ/ and /ð/ sounds to Iranian EFL learners. To achieve this objective, after 30 students studying English at a language institute took a placement test, the intermediate-level students were selected based on their scores on this test. They were randomly assigned to one experimental group and one control g...

We present in this report a summary of the main results produced in the five years of the GERINDO research project. The aim of this project is to address the increasing demand for software tools capable of dealing with information available in large document collections, such as the World Wide Web. It involves efforts of researchers from three Brazilian universities to develop core technologies...

The Web has been rapidly “deepened” by massive databases online: Recent surveys show that while the surface Web has linked billions of static HTML pages, a far more significant amount of information is “hidden” in the deep Web, behind the query forms of searchable databases. With its myriad databases and hidden content, this deep Web is an important frontier for information search. In this pape...

BACKGROUND Safety analyses of transcranial therapeutic ultrasound procedures require knowledge of the dependence of the rupture probability and rupture time upon sonication parameters. As previous vessel-rupture studies have concentrated on a specific set of exposure conditions, there is a need for more comprehensive parametric studies. METHODS Probability of rupture and rupture times were me...
