Evaluation of high-frequency ultrasonography for diagnosis of carpal tunnel syndrome.

The aim of this study was to assess the sensitivity and specificity of ultrasonography in the diagnosis of carpal tunnel syndrome. The cross-sectional area of the median nerve at the carpal tunnel for a positive diagnosis had a sensitivity of ∼ 98.6% but a specificity of 60%.

Molecular Approach for Understanding the Stability, Collision, and Coalescence of Bulk Nanobubbles.

Though long-lived nanobubbles (NBs) have been reported by multiple researchers, the underlying reason behind their stability is still obscure. Some of the conjectured reasons include diffusive shielding, the presence of surface charges, and stability due to contamination. Still, the stability of NBs against coalescence and Ostwald ripening is not confirmed.
