Conclusions: Lung ultrasound may help highlight pulmonary gangrene, a poorly-known disease, with this new ultrasonographic description. The next step will be to ascertain the relation between this new ultrasound feature and pulmonary gangrene and to assess how this bedside diagnosis could impact the prognosis of the disease.

Therefore, performance improvement of high-frequency ultrasonic transducers can enhance the performance of the whole ultrasound instrument. To improve the echo-signal quality, such as the amplitudes, signal distortions, and bandwidths, negative-group-d...
In this paper, we demonstrate 1-kHz-repetition-rate laser ultrasound in carbon-fiber-reinforced plastics (CFRPs). A ZGP master oscillator ...
In this study, we developed an ultrasound-assisted fractional precipitation for the purification of poorly water-soluble anticancer agent paclitaxel. The effects of ultrasound power (80, 180, 250, and 380 W) were investigated in samples of different purity (20.4, 63.6, and 92.7%) for precipitation. Higher precipitation rate and shorter precipitation time were found with ultrasound treated solutions than with those without ultrasound. When the experimental data were applied to the Johnson-Mehl-Avrami-Komolgorov (JMAK) equation, the rate constant increased to 200-500-fold for 20.4% of sample purity, 150-250-fold for 6...
Conclusions Uterus-preserving LLSM (abdominocervicopexy) was found to be effective for the correction of apical and anterior prolapse with high levels of patient satisfaction. Significant improvements in urge symptoms and frequency of nocturia were observed. Pelvic floor ultrasound outcomes may be useful when comparing this procedure with other surgical techniques.

Conclusions: The MRI-TRUS image fusion is a feasible tool for the visualization of the prostate gland, particularly at the apex and base of the gland. Tumor identification presents the potential for dose escalation using fusion, especially for anteriorly located tumors. PMID: 31523238 [PubMed]
