Article Abstract
The effect of the ultrasonic treatment on the physicochemical properties, oil-holding capacities, foaming capacities, and TLR2-affinity of the polysaccharides from Pholiota nameko (PNPS), was evaluated. Compared with the protein content of PNPS before ultrasonic treatment, the protein content of PNPS all presented a decrease under different ultrasonic conditions. The viscosity of PNPS showed a decrease when the ultrasonic intensity was strong enough, as well as the molecular weight. The oil-holding capacity and the foaming capacity of PNPS showed a continuous increasing trend with the increase of the ultrasonic treatment time under a set ultrasonic power of 400 W. Further, the ultrasonic operation could induce the decrease of the affinity binding between PNPS and the receptor proteins TLR2. These data confirmed that applying the ultrasonic treatment could obtain PNPS with high carbohydrate contents, low viscosity and low TLR2-affinity under proper ultrasonic condition.

Sonazoid, a combined blood pool and Kupffer-cell agent, can be specifically phagocytosed by Kupffer cells in the liver, allowing lesion detection and characterization of focal liver lesions (FLLs) at the post-vascular phase apart from the vascular phase which is similar to that of other second-generation US contrast agents. Sonazoid CEUS is currently approved for use in some Asian countries. With the increasing use of Sonazoid CEUS for FLLs in clinical practice, developing consensus or guidelines to help standardize its use is required.

Objective: To evaluate clinical and laboratory effectiveness of ultrasound treatment for purulent wounds.
Material And Methods: The study enrolled 46 patients with purulent wounds divided into the main group (23 patients, ultrasonic treatment) and the control group (23 patients, traditional treatment). We assessed treatment effectiveness considering visual data, quality of granulation tissue, wound defect area and marginal epithelialization, complete blood count and C-reactive protein.

Background: Point-of-care ultrasonography has become a valuable tool for assessing diaphragmatic function in critically ill patients receiving invasive mechanical ventilation. However, conventional diaphragm ultrasound assessment remains highly operator-dependent and subjective. Previous research introduced automatic measurement of diaphragmatic excursion and velocity using 2D speckle-tracking technology.

Introduction: Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system (CNS). CD4 CD25 Tregs, which normally suppress immune responses, exhibit impaired function in MS. Treg-derived extracellular vesicles (EVs) carry immunoregulatory proteins and miRNAs that modulate T-cell activity.

The effect of sonocatalysis on anticancer treatment is always restricted by rapid recombination of charge and low utilization of the ultrasonic cavitation effect. Herein, cobalt-doped prussian blue (PB) nanocubes were synthesized, and then they were etched by acidic solution to obtain amorphous Co-FePB@1h with abundant defects including: Fe/Co defects, Fe-(CN) vacancies, and dangling bonds. Both doping and defect engineering contribute to decreasing the band gap and promoting charge separation.
