• Application of microbubbles compared directly with conventionally sized bubbled for ozonation. No evidence microbubble collapse causing radical formation was seen. The level •OH-exposure is linked to the effective dose and pH system. Future ozonation system design should focus on those factors deliver •OH based benefits. application water treatment an emerging technology which has been shown ...
Objective and Impact Statement . To develop an approach for individualized closed-loop feedback control of microbubble cavitation to achieve safe effective focused ultrasound in combination with microbubble-induced blood-brain barrier opening (FUS-BBBO). Introduction FUS-BBBO is a promising strategy noninvasive localized brain drug delivery growing number clinical studies currently ongoing. Rea...
Most of the anticancer agents cannot be efficiently delivered into the brain tumor because of the existence of blood-brain tumor barrier (BTB). The objective of this study was to explore the effect of microbubble-enhanced diagnostic ultrasound (MEUS) on the BTB permeability and the possible mechanism. Glioma-bearing rats were randomized into three groups as follows: the microbubble-enhanced con...
Ultrasound is the most commonly used abdominal imaging modality. The addition of color and spectral Doppler imaging has been particularly beneficial. When ultrasound findings are nonspecific, however, patients are generally referred to CT or MRI. A contrast-enhanced ultrasound examination could alleviate the need for these more expensive imaging investigations, and a number of micro-bubble-base...
