Acoustic Sensing as a Tool for Brain Tumor Diagnostics

Advanced Sensor Research, Volume 5, Issue 2, February 2026.
Surface acoustic wave (SAW) sensing is used to distinguish non‐neoplastic brain tissue from primary and metastatic tumors based on their acoustic attenuation signatures. Ex vivo human brain samples reveal clear tissue‐specific mechanical profiles, correlating with stiffness and malignancy.

Surface acoustic wave-induced electroluminescence intensity oscillation in planar light-emitting devices

, 2005
Electroluminescence emission from surface acoustic wave-driven light-emitting diodes (SAWLEDs) is studied by means of time-resolved techniques. We show that the intensity of the SAW-induced electroluminescence is modulated at the SAW frequency (~1 GHz ...

Preventive Effect of Powder Bergamot Juice (Citrus bergamia Risso & Poiteau) on Pathophysiological Processes of Renal Disease in an Experimental Western Diet Model

Molecular Nutrition &Food Research, Volume 70, Issue 3, 13 February 2026.
Excessive intake of sugars and fats contributes to obesity and renal dysfunction. Natural bioactive compounds, such as those found in bergamot (Citrus bergamia), have been studied for their protective potential. In an experimental rat model, bergamot supplementation reduced weight gain, improved kidney function, and decreased oxidative stress markers ...
