(fibroblast-free) spheroids; (b) US-induced inertial cavitation combined with Gemcitabine significantly decreased spheroid viability compared to Gemcitabine alone; (c) both cavitation and chemotherapy affected KPC cell viability but not that of fibroblasts, confirming the protective role of the latter ...
the way in which nano-systems act against a tumor could in principle also be adjusted by accurately selecting the nano-system among a large choice and by tuning the values of the ultrasound parameters, which can lead, due to their mechanical nature, to specific effects such as cavitation that...
3.1. Acoustic cavitation theory The frequency of US is generally between 20 KHz and 10 MHz and US in the liquid cause acoustic cavitation, which is the foundation of sonochemical synthesis. Sonochemical synthesis has three phases:I. Nucleation. US causes local tensile stress in the liquid, result...
7). Regardless of the evolution into porencephaly, a cavitation resulting from PHI is usually single, asymmetric and persistent. Conversely, cysts of periventricular leukomalacia typically show a symmetrical, mainly posterior distribution and tend to disappear within few weeks, insomuch that they are...

Cavitation and microstreaming induced by ultrasound caused protein unfolding and exposed intramolecular hydrophobic groups (Wen et al., 2019), promoting the binding of RBP with LU, and leading to an increase in the UV absorption intensity of RLC. The interactions between RBP and LU were strongest...

The corresponding cavitation zone is marked in Fig. 7(c) under 1D ultrasound for such bubbles. It can be seen clearly that the cavitation can only take place within the sample bottom, which is close to the ultrasound source. As for the 3D ultrasounds, the cavitation volume drawn in Fig...
In general, inactivation effect of ultrasound is attributed to intracellular cavitation that disrupt cellular structural and functional components up to the point of cell lysis (Figure X) [6]. 7.3. US assisted defoaming US as a defoaming technique, was suggested for the first time in 1944 [...
