Endosopic Ultrasound, 2012 Endobronchial ultrasound (EBUS), one of the most important advances in pneumology in recent years, provides visualization of bronchial walls and parabronchial structures, extending the diagnostic spectrum of bronchoscopic techniques. Two different techniques are available: radial endobronchial ultrasound and the technique of ultrasound-guided ...

Ultrasound to Enhance a Liquid–Liquid Reaction [PDF]
, 2010 Liquid–liquid mass transfer with ultrasound was investigated experimentally during the hydrolysis of n-amyl acetate. Power ultrasound is supposed to improve the yield and kinetics of such multiphase chemical reactions thanks to the mechanical effects of ...

Transcutaneous ultrasound energy harvesting using capacitive triboelectric technology
Science, 2019 A sound way to deliver power Implanted medical devices, such as pacemakers and neurological stimulators, require a source of power, usually in the form of a battery. If a battery is implanted with the device, replacing it would require additional surgery.

Blood–brain barrier opening in Alzheimer’s disease using MR-guided focused ultrasound
Nature Communications, 2018 Magnetic resonance-guided focused ultrasound in combination with intravenously injected microbubbles has been shown to transiently open the blood–brain barrier, and reduce beta-amyloid and tau pathology in animal models of Alzheimer’s disease.

Molecular Oncology, EarlyView.Breast cancer metastasis is associated with myeloid cell dysregulation and the lung‐specific accumulation of tumor‐supportive Gr1+ cells. Gr1+ cells support metastasis, in part, through a CHI3L1‐mediated mechanism, which can be targeted and inhibited with cargo‐free, polymeric nanoparticles.

Molecular Oncology, EarlyView.This study presents a novel AI‐based diagnostic approach—comprehensive serum glycopeptide spectra analysis (CSGSA)—that integrates tumor markers and enriched glycopeptides from serum. Using a neural network model, this method accurately distinguishes liver and pancreatic cancers from healthy individuals.
