Oat is a promising high-quality protein source but it requires structural and functional modifications to diversify its application. The current investigation was focused on the impact of different powers of ultrasonic waves (200, 400, and 600 W) on structural and functional characteristics of oat protein isolates to improve its techno-functional properties. Higher strength ultrasound waves generated flat sheet structures which were observed while analyzing microstructure of oat protein isolate (OPI). However, non-significant variation in molecular weight distribution were observed in different treatments. At 600 W power of ultrasonic waves the protein fragments show local accumulation, increased α-helix content. Due to uncoiling of protein structure decrease in β-sheets and β-turns was also observed at 600 W. Protein turbidity decreased significantly under low power ultrasonic treatment (200 W) which significantly increased at higher power. Moderate ultrasonic treatment (400 W) promoted protein dissolution, and maintained a good balance between β-sheets (71.04 ± 0.08), α-helix (16.27 ± 0.02) and β-turns (12.68 ± 0.03), exhibiting optimized flexibility and structural integrity. Whereas, higher strength (600 W) significantly destroyed protein structure. The amino acid content decreased significantly with increasing ultrasonic power. The thermal characteristics of OPI remained unaffected after ultrasound treatment. In conclusion, modifications of secondary and tertiary structure induced by moderate ultrasonic treatment (400 W) improved functional properties of OPI. The 400 W treatment resulted in highest essential amino acid content (EAA) i.e., 22.75 ± 0.82 mg/100 mg and total amino acid content (TAA) i.e., 64.94 ± 2.7 mg/100 mg, which are significantly higher than WHO and FAO standards, suggesting best total and essential amino acid production in comparison to other treatments.</p>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"112 ","pages":"107204"},"PeriodicalIF":8.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142852028","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}

Polysaccharides, as a typical prebiotic, have been extensively employed in stroke treatment. In our previous study, Pueraria lobata polysaccharide (PLP-3) with antioxidant activity was prepared via water extraction and alcohol precipitation combined with ultrasonic degradation. In this study, the effects of PLP-3 on ischemia brain injury and its regulatory effects on the gut microbiota were further investigated. The results demonstrated that PLP-3 effectively reduced the infarct area, improves neurological function, and alleviates neuronal damage of cerebral ischemia injury. Mechanistically, PLP-3 significantly reduces serum LPS levels in MCAO mice, inhibiting TLR-4 activation in brain tissue and thereby reducing IL-1β and TNF-α levels. Meanwhile, PLP-3 significantly repaired the intestinal barrier injury by increasing the expression of tight junction proteins (ZO-1 and Occludin) and increasing the number of goblet cells. Additionally, the structure and composition of gut microbiota in MCAO mice after PLP-3 intervention, were also significantly changed, especially the enrichment of Lactobacillus and the reduction of Corynebacterium and Staphylococcus. At the same time, short chain fatty acid, metabolites of gut microbiota, were also significantly increased and significantly correlated with the abundance of Lactobacillus. Moreover, LC-MS untargeted metabolomics revealed that PLP-3 significantly improves the intestinal metabolic profile after cerebral ischemia injury, upregulating the amino acid biosynthesis pathway and enriching amino acids such as glutamine and arginine, as well as neuroprotective flavonoids such as fisetin and liquiritigenin. These results suggested that PLP-3 could protect mice from cerebral ischemia-reperfusion injury by regulating gut microbiota and repairing gut barrier, inhibiting brain LPS/TLR4/MyD88 inflammatory pathway, therefore we provide a theoretical basis for PLP-3 as a functional food to prevent ischemic brain injury.</p>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"112 ","pages":"107200"},"PeriodicalIF":8.7,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142826983","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}

Utilizing an in-situ normal pressure bubble generation and observation system that was developed, this study examined the translational behavior of micrometer-scale normal pressure bubble pairs with initial radius ratio of 1:1 and 2:1 under ultrasonic field excitation. A velocity-distance curve was proposed to quantify the secondary Bjerknes forces during various interaction stages of the bubbles. The findings revealed that equal-sized bubbles underwent an acceleration phase, a deceleration phase, and a velocity jump phase during attraction in both strong and weak acoustic fields. In contrast, bubbles of unequal sizes, due to different oscillation frequencies, experienced multiple acceleration and deceleration phases, presenting asynchronous behaviors. The study further explored the effects of the initial bubble radius, shape oscillation, and volume oscillations on the attraction speed. Results showed that the velocity of the bubble’s centroid decreased with an increase in the initial radius, while intensified volume oscillations increased the secondary Bjerknes force, thereby increasing the centroid’s velocity. Moreover, strong acoustic fields were more likely to induce severe volume and shape oscillations in bubbles than weak fields. The irregular shape oscillations in twin bubbles resulted in shortened durations of acceleration and deceleration phases, reduced peak velocities of acceleration phase, and diminished acceleration during the velocity jump phase.
