This study systematically investigates the coupled mechanical vibration and cavitation mechanisms of a novel flexible ultrasonic guidewire during ablation of calcified, lipid-rich, and thrombotic occlusion mimics. Integrating numerical simulations and experimental validation, this work elucidates the dynamic interplay between ultrasonic parameters and tissue-specific ablation outcomes. For calcified mimics, mechanical vibrational impact is the dominant ablation mechanism, achieving substantial material removal primarily through fracture. Lipid-rich tissue ablation is driven by emulsification via cavitation microjets and acoustic streaming, generating microparticles with sizes of 10-250 μm, controllable by ultrasonic power. Thrombus ablation involves initial penetration followed by erythrocyte lysis, primarily mediated by transient cavitation. Crucially, guidewire bending significantly attenuates tip vibration amplitude, resulting in a reduction of 14.3-30.9 %, with titanium alloy exhibiting superior energy transmission stability under curvature compared to nickel-titanium. These findings highlight distinct, tissue-dependent ablation paradigms: mechanical fragmentation for hard tissues compared to cavitation and streaming induced emulsification or lysis for soft tissues. This mechanistic understanding is foundational for designing adaptive ultrasonic guidewires capable of adjusting energy delivery modes based on real time feedback of tissue characteristics, thereby enhancing the precision and efficacy of endovascular interventions.","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":" ","pages":"107474"},"PeriodicalIF":9.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144740777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional methods are often invasive, complex, and costly, while focused ultrasound (FUS) poses risks related to biocompatibility and tissue damage. Distinguished by its helical phase structure and rotational energy distribution, focused acoustic vortex (FAV) theoretically generates stronger rotational forces and acoustic streaming than FUS under identical acoustic conditions. This study investigates the feasibility of FAV technique for biofilm removal. Biofilms in vitro model were established using Escherichia coli, and a 2-MHz custom-built ultrasound transducer was employed to generate either FAV or FUS. Results indicated that FAV activation generated a centripetal vortical flow with rapid rotation, which was adjustable via acoustic pressure and duty cycle. Conversely, FUS generated solely outward acoustic streaming, exhibiting a flow velocity 43.6 % lower than that of FAV. At 1.75 MPa, implementing a 10 % duty cycle and a 180 s treatment, FAV removed 97 % of the biofilm, whereas FUS removed only 7 %. To achieve a comparable removal rate (95.8 %), FUS required 4 MPa for 10 minutes. Streaming velocity (R2 = 0.99) exhibited a strong correlation with biofilm removal, while inertial cavitation (R2 = 0.19) exhibited a weak correlation; thus, the former was identified as the primary contributing mechanism. Importantly, FAV treatment resulted in minimal thermal elevation (<5 °C) and no significant reduction in cell viability, demonstrating its biosafety under the applied acoustic parameters. Synergistic tests with antibiotics further suppressed biofilm regrowth for up to 72 h, reducing bacterial concentration by 91 %. Future work will focus on in vivo biofilm models and assessing the safety and efficacy of combined treatments to advance clinical applications.","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":" ","pages":"107423"},"PeriodicalIF":9.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144332150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results showed the pH-shifting combined with ultrasound treatment led to the exposure of internal hidden hydrophobic residues, disruption of hydrogen bonding. The surface hydrophobicity and molecular flexibility of globulin increased, along with improved fluorescence intensity. The combined treatment conditions boosted the interfacial protein adsorption content of globulin-based emulsions significantly. The resulting emulsions were uniformly dispersed without aggregation, exhibited optimal storage, thermal, and cold storage stability, similar to the performance of the sodium caseinate.

However, research on the extraction and purification of CGA from dandelion, as well as its bioactivity, is insufficient. Therefore, this study developed an efficient and economic method for extracting CGA from dandelions using ultrasonic-assisted deep eutectic solvents. The DES system comprised betaine and oxalic acid, demonstrated high extraction efficiency, and was identified as the optimal extraction solvent. Furthermore, Response Surface Methodology (RSM) was employed to optimize the extraction conditions, which included: water content of 42 %, ultrasonic power of 300 W, ultrasonic temperature of 70 °C, ultrasonic time of 32 min, and solid-liquid ratio of 1:30 g/mL. Under these conditions, the extraction yield of CGA reached 4.27 mg/g. Dandelion samples treated with ultrasound-assisted DES had improved extraction efficiency. Following further purification with macroporous resin, the purified extract of CGA (PECGA) demonstrated significant antioxidant activity. Moreover, this ultrasonic-assisted PECGA showed considerable antibacterial efficacy against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). This study provides evidence for potential applications of CGA extracted from dandelions as a natural antioxidant and antibacterial agent in the food and pharmaceutical industries.","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"122 ","pages":"107579"},"PeriodicalIF":9.7,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145211303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results demonstrated that low-power and low-temperature ultrasonic treatment effectively modulated the sugar-acid ratio in SRW. Tannin content exhibited minimal temperature dependence but was significantly influenced by ultrasonic power and duration, with duration exerting the strongest effect. Total ester content decreased with prolonged ultrasound exposure, though this reduction was mitigated under low-power conditions. Phenolic content declined as ultrasonic intensity increased. Sensory evaluation identified optimal aging parameters at 20 °C, 90 min, and 200 W.

This study assessed the influence of process variables on the ultrasonic-assisted extraction of DAO from pea sprouts. DAO activity (DAOac), protein content (PC), and their ratio (DAOsac) were measured on extracts obtained at different times (10, 20, 30, 40 min), temperatures (10, 20, 37 °C), and acoustic pressures (0, 29, 75 kPa). Response surface methodology (RSM) and multivariate regression models were applied to identify the optimal conditions and predictive multivariate models were assessed to develop a process control tool. Ultrasound application significantly enhanced DAO extraction, increasing DAOac, PC, and DAOsac by up to 34.4, 14.9, and 19.4 % compared to conventional methods. The application of a moderate acoustic pressure (29 kPa) maximized yields, while a higher one (75 kPa) reduced extraction time. The moderate optimal temperature identified, 23.0 ± 0.3 °C, represents a clear advantage for the process scaling-up. The Support Vector Machine (SVM) model showed the best predictive performance (adjusted coefficient of determination; R2adj > 92 % and mean relative error; MRE < 4 %), accurately estimating dependent variables based on process conditions.
