Oat β-glucan helps treat diarrhea and other associated disorders, because it can regulate intestinal microbiota. We investigated the therapeutic effects and mechanism of oat β-glucan combined with montmorillonite powder on diarrhea induced by Senna leaf extract in young Sprague-Dawley rats. Compared with the diarrhea-induced model group (DM), the combined treatment, especially in the group treated with a medium dose of Montmorillonite powder plus oat β-glucan (M+G2), effectively reduced the diarrhea (<em>P</em> &lt; 0.05) and inflammation indices, alleviated damage to the colon, and promoted weight gain in rats. In the combined treatment group, the relative abundance of Firmicutes increased at the phylum level, while the relative abundance of Proteobacteria and Actinobacteria decreased. At the genus level, the <em>Lactobacillus</em> content recovered, and the proportion of conditional pathogens, such as <em>Prevotella</em> and <em>Paraprevotella</em> decreased. M+G2 treatment significantly reduced diarrhea in young rats, restored intestinal microbiota diversity, and promoted the production of short-chain fatty acids (SCFAs). Based on metabolomics, the mechanism of the anti-diarrheal effect of M+G2 treatment may be related to the regulation of glucose and amino acid metabolism. The metabolic micro-environment was improved through the pentose phosphate and vitamin B6 pathways. The core metabolic regulator in metabolic network analysis was L-aspartic acid. Overall, our findings suggest that the combined treatment of oat β-glucan and montmorillonite powder may provide an effective therapeutic strategy for treating diarrhea and associated disorders by regulating the inflammatory biomarkers, SCFAs, and intestinal microbiota.</p></div>","PeriodicalId":12385,"journal":{"name":"Food Hydrocolloids for Health","volume":"4 ","pages":"Article 100169"},"PeriodicalIF":1.9,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667025923000535/pdfft?md5=657660c9350726ed03120d3d7722dccd&pid=1-s2.0-S2667025923000535-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135565138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study involved evaluating their biological characteristics, such as their antioxidant, antidiabetic, antimicrobial, antibiofilm, and antiproliferative activities at various concentrations, as well as investigating their effects on the gut microbiome through <em>in vitro</em> fecal fermentation. Moreover, the study analyzed the rheological properties of the EPSs in fermented bovine milk.

Our previous study which reported the complexation between zein and laponite to form coacervates and their future prospect as dual drug carriers has been extended in this work. The present work has validated the usefulness of the synthesized coacervate as a dual-drug carrier for a hydrophilic drug (cisplatin) and a hydrophobic drug (curcumin) towards a breast cancer cell line (MDA-MB-231). The MTT assay and flow cytometry data for MDA-MB-231 cells suggested that the coacervate carrying dual drugs effectively transported anticancer drugs to the cancer cells, thereby arresting their cell cycle in the S phase (by neutral coacervates, X₁) and in the G₂/M phase (by charged coacervates, X₂). Further, it is also revealed that the amount of cisplatin needed to achieve half maximal inhibitory concentration (IC₅₀) was reduced by a maximum of 70% when flavonoid (curcumin) was used in combination with cisplatin due to synergistic effect.</p></div>","PeriodicalId":12385,"journal":{"name":"Food Hydrocolloids for Health","volume":"4 ","pages":"Article 100164"},"PeriodicalIF":1.9,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49735219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
