The structural characteristics, antioxidant and hypoglycemic effects of TGEP-U and TGEPs obtained by hot water extraction (TGEP-H) were then compared. Consequently, the optimum extraction conditions predicted by RSM for TGEP-U were obtained as adding water at a ratio of 31 mL/g and extracted for 32 min under an ultrasound power of 440 W. In the verification experiment, the actual yield of TGEP-U was 7.32 ± 0.18 %. It was found that UAE could increase the yield and the total sugar content of TGEPs. Meanwhile, chemical composition analysis showed that both TGEP-U and TGEP-H were mainly composed of mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose, arabinose, and fucose, but the monosaccharide molar ratios were changed by UAE. Analysis of molecular weight (Mw) revealed the presence of three primary constituents within TGEP-U, and four main components in TGEP-H, and UAE reduced the average Mw of TGEPs. No obvious difference was found in the Fourier transform infrared spectroscopy analysis of TGEP-U and TGEP-H. The Congo red and Circular dichroism tests demonstrated that TGEP-U and TGEP-H had non-three helical structure. Scanning electron microscope observation further revealed that the aggregation of functional groups within TGEPs may be influenced by ultrasound, thereby affecting their powder morphology. TGEP-U has slightly poorer thermal stability than TGEP-H, which may be affected by ultrasonic cavitation effects.

Using this integrated model, we investigated the influence of nonlinear dual-frequency ultrasound parameters on ADV dynamics and bioeffects by incorporating tissue viscoelasticity through parametric studies. Our results demonstrated that the proposed model accurately captured the entire ADV process, ensuring continuous vapor bubble formation and evolution throughout the phase transition process. Moreover, the applied unified theory for bubble dynamics can simulate intense bubble collapse with high Mach Number as a result of the nonlinear effects of dual-frequency ultrasound. In addition, cavitation-associated mechanical and thermal damage appeared to be more strongly correlated with rapid bubble collapse than with maximum bubble size. Our research also revealed that the mechanical and thermal effects could be regulated independently to some extent by adjusting dual-frequency ultrasound parameters, as they presented differing sensitivities to frequency and acoustic power.

DOP has demonstrated the ability to improve the general condition of mice with cyclophosphamide-induced immunosuppression. It mitigates damage to the thymus and spleen tissues, increases white blood cell counts, regulates the ratio of T lymphocytes and the levels of related factors, enhances macrophage phagocytic function to improve nonspecific immune responses, and boosts the levels of immunoglobulins IgA and IgG to enhance specific immune function. Therefore, DOP can alleviate immunosuppression induced by cyclophosphamide.</div></div>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"114 ","pages":"Article 107248"},"PeriodicalIF":8.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143169378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
