Focused Ultrasound‐Induced Mechanical Ablation Affects the Carbohydrate Metabolism of Residual/Peri‐Focally Localized Glioblastoma Cells

International Journal of Cancer, EarlyView.
Glioblastoma (GBM) is highly aggressive and therapy‐resistant, warranting exploration of novel treatment strategies, among them mechanical high‐intensity focused ultrasound (mFUS), which holds significant promise for tumor ablation. The present study examined mFUS‐induced changes specifically in carbohydrate metabolism, which affects vulnerability to ...

Planar laser induced fluorescence for temperature measurement of optical thermocavitation [PDF]

, 2019
Pulsed laser-induced cavitation, has been the subject of many studies describing bubble growth, collapse and ensuing shock waves. To a lesser extent, hydrodynamics of continuous wave (CW) cavitation or thermocavitation have also been reported.

Cavitation inception from bubble nuclei [PDF]

Interface Focus, 2015
Abstract The tensile strength of ordinary water such as tap water or seawater is typically well below 1 bar. It is governed by cavitation nuclei in the water, not by the tensile strength of the water itself, which is extremely high. Different models of the nuclei have been suggested over the years, and experimental investigations of ...

From regulatory mechanisms to cutting‐edge applications: Research progress of ultrasound, electrical, magnetic, and optical stimulation in neural modulation

Journal of Intelligent Medicine, EarlyView.
Abstract In recent years, the clinical treatment and symptom management of neurological disorders have faced significant challenges due to the high complexity of the nervous system's structure and function. Against this backdrop, physical stimulation techniques have emerged as a vital complementary approach to traditional pharmacological treatments and

Recent observations on cavitation and cavitation noise [PDF]

, 1989
This paper is primarily concerned with the acoustics of traveling bubble cavitation around foils or headforms. We begin with observations of individual bubbles and the acoustic signals they emit, our purpose being to identify areas of research which ...

Non-spherical collapse of an air bubble subjected to a lithotripter pulse [PDF]

, 2008
In order to better understand the contribution of bubble collapse to stone comminution in shockwave lithotripsy, the shockinduced and Rayleigh collapse of a spherical air bubble is investigated using numerical simulations, and the free-field collapse ...

Effect of thermosonication on the UHPLC‐QTOF‐IMS‐based metabolomic profile of orange juice

JSFA reports, EarlyView.
Abstract Background This study investigated the impact of thermosonication on the metabolomic profile of orange juice to understand processing‐induced alterations in bioactive compounds and quality attributes. Results Moderate thermosonication at 45°C preserved structural siloxanes and certain amino acids, whereas higher temperatures between 60 and 75 ...

Cavitation of Electrons Bubbles in Liquid Helium Below saturation Pressure

, 2005
We have used a Hartree-type electron-helium potential together with a density functional description of liquid $^4$He and $^3$He to study the explosion of electron bubbles submitted to a negative pressure.
