MicroRNAs (miRNAs), as a novel class of small noncoding RNAs, have been identified as important transcriptional and posttranscriptional inhibitors of gene expression. Ultrasound-targeted microbubble destruction (UTMD) is a noninvasive method for microRNA delivery. We aimed to investigate the effect of UTMD of miR-133a on breast cancer treatment. It has been reported that miRNA-133a is involved ...

Non-muscle invasive bladder cancer is one of the most common tumors of the urinary tract. Despite the current multimodal therapy, recurrence and progression of disease have been challenging problems. We hereby introduced a new approach, ultrasound-assisted intravesical chemotherapy, intravesical instillation of chemotherapeutic agents and microbubbles followed by ultrasound exposure. We investi...

nergy efficiency is a global goal in the fight against warming. Research on reducing drag one of ways to improve energy efficiency. The research method used injection micro-sized bubbles and ultra-fine barge ship model. Microbubble Drag Reduction (MBDR) Ultrafine Bubble (UFBDR) are two methods that can play an essential role surface ship's hull. Factors affect effectiveness these ratio, locatio...

Focused ultrasound and microbubbles have been extensively used to generate therapeutic bioeffects. Despite encouraging in vivo results, there remains poor control of the magnitude and spatial distribution of these bioeffects due to the limited ability of conventional pulse shapes and sequences to control cavitation dynamics. Thus current techniques are restricted by an efficacy-safety trade-off...

t is well known that microbubble destruction can occur uring contrast echocardiography, primarily by acoustic avitation (1). The propensity of microbubbles to undergo his process when exposed to ultrasound depends on physcal properties of both the bubbles themselves and the ltrasound beam. Higher rarefactional peak amplitude (a easure of ultrasonic acoustic power) and lower frequencies ause gre...
