Ablation Techniques
Abstract
The goal of this study is to develop a focal zone sharpening strategy that produces more precise lesions for pulsed cavitational ultrasound therapy, or histotripsy. Precise and well-confined lesions were produced by locally suppressing cavitation in the periphery of the treatment foc...

Marine Biotechnology (12)4 2010
Abstract
We expressed an Escherichia coli nitroreductase (Ntr) gene in the male germ line of zebrafish. The Ntr gene encodes an enzyme that can convert prodrugs such as metronidazole (Met) to cytotoxins. A fusion protein eGFP:Ntr (fusing Ntr to eGFP) under control of approximately 2 kb putative promoters of...

Hepatology (52)2 2010
Abstract
Loco-regional treatments play a key role in the management of hepatocellular carcinoma (HCC). Image-guided tumor ablation is recommended in patients with early-stage HCC when surgical options are precluded. Radiofrequency ablation has shown superior anticancer effects and greater survival benefit wi...

Abstract
We investigated natural and lesion-induced apoptosis in the developing rat dorsal lateral geniculate nucleus (dLGN). These lesions involved: i) monocular enucleation, and ii) unilateral ablation of the visual cortex at different postnatal ages before eye opening. We identified dying cells as apoptot...

Abstract
Of 614 patients with DTC during our period, 504 (83%) underwent total thyroidectomy and 104 (17%) underwent lesser surgery. Radioiodine administration was reported for 394 patients who underwent total thyroidectomy with a dose range of 24 to 297 mCi (mean of 116 mCi). Ten-year survival was higher fo...

Comparison between medical and surgical groups showed higher improvement in both perennial and seasonal, respectively, in nasal obstruction, sneezing, rhinomanometry, and rhinomanometry after NPT. Itching improved only in perennial allergen type. Rhinoe...

Abstract
We propose an original treatment strategy that combines ultrasound imaging and therapy using a dual-mode transducer rotating at 8 revolutions per second. Real-time B-mode imaging was interrupted to emit high-intensity ultrasound over a selected therapy aperture. A full 360 degrees image was taken ev...

Abstract
We also found that, on average, elastic modulus imaging can more accurately depict thermal ablation zones, when compared to strain imaging (14.7% versus 22.3% absolute percent error in area measurements, respectively). Furthermore, elastic modulus imaging also provides higher (more than a factor of...

Abstract
We conclude that erbium lasers (Er:YAG and Er,Cr:YSGG) are most efficient and, with the right parameters, the thermal side effects are small. There is a substantial need for "gold standards", although this is difficult to establish in practice owing to different laser parameters (including pulse rep...

Abstract
The hypothesis was tested that estradiol (E2) from the ovarian follicles controls time of luteolysis. Time of luteolysis was evaluated by multiple measures of corpus luteum (CL) structure (area, volume) and function (progesterone [P4], luteal blood flow). The hypothesis for experiment 1 was that rep...
