Various tips are available for phacoemulsification in cataract surgery. Evidence-based data can inform ophthalmologists, especially inexperienced ones, on tip selection. We retrospectively evaluated the energy efficiency and other parameters of two ultrasonic phacoemulsification and aspiration tips across different nuclear hardness grades in 342 cataract patients (342 eyes) with nuclear hardness grades II to IV.

Non-invasive, low intensity focused ultrasound is an emerging neuromodulation technique that offers the potential for precision, personalized therapy. An increasing body of research has identified mechanosensitive ion channels that can be modulated by FUS and support acute electrical activity in neurons. However, neuromodulatory effects that persist from hours to days have also been reported.

Purpose: This study aimed to explore a combined transrectal ultrasound (TRUS) and radiomics model for predicting tumor regression grade (TRG) after neoadjuvant chemoradiotherapy (NCRT) in patients with locally advanced rectal cancer (LARC).
Methods: Among 190 patients with LARC, 53 belonged to GRG and 137 to PRG. Eight TRUS parameters were identified as statistically significant (P < 0.
Innovative ultrasound assisted synthesis of sponge like cerium dioxide nanostructure using Rosa Damascena extract and its efficient performance for cancer therapy.

Rheumatoid arthritis (RA) is an autoimmune disease that seriously threatens human health and affects the quality of life of patients. At present, pharmacotherapy is still the mainstream treatment for RA, but most methods have shortcomings, such as poor drug targeting, a low effective drug dosage at the inflammatory site, and high systemic toxicity. The combined application of drug-loaded nanobubbles and ultrasound technology provides a new technique for the treatment of RA.
