Ultrasound-mediated targeted drug delivery generated by multifocal beam patterns: an in vitro study.
Dana Gourevich et al.
Ultrasound in medicine & biology, 39(3), 507-514 (2013-01-22)
Ultrasound-mediated targeted drug delivery has been a subject for a dedicated research activity for several decades. Nevertheless, in vitro studies in this field of research are characterized by their inconsistencies. To improve the repeatability of such experiments, a novel approach of

Contrast-enhanced ultrasound with microbubbles has shown promise in detection of prostate cancer (PCa), but sensitivity and specificity remain challenging. Targeted nanoscale-contrast agents with improved capability to accumulate in tumors may result in prolonged signal enhancement and improved detection of PCa

BACKGROUNDSalt-sensitive hypertension is often accompanied by insulin resistance in obese individuals, but the underlying mechanisms are obscure. Microvascular function is known to affect both salt sensitivity of blood pressure and metabolic insulin sensitivity. We hypothesized that excessive salt intake increases
