Quantum dot nanobead immunochromatographic assay (QB-ICA) based on the BsMAb was developed for the simultaneous detection of AFB1 and AMD in four feed samples (suckling pig feed, piglet feed, sow feed, and compound feed for laying ducks). Under optimal experimental conditions, the LOD values of QB-ICA for AFB1 in four feed samples were 0.188, 0.221, 0.233, and 0.306 μg/kg, respectively. The LOD values of QB-ICA for AMD in the same feed samples were 0.125, 0.187, 0.076, and 0.191 μg/kg, respectively. The recovery rates of QB-ICA for AFB1 and AMD ranged from 91.55% to 150.87% and from 91.62% to 138.42%, respectively. The variation coefficients were all less than 15%. The proposed QB-ICA had high reliability and specificity for the simultaneous detection of AFB1 and AMD, providing a platform for simultaneous detection of hazardous substances.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43486009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The banana starch diet reconstructed the gut microbiota and increased their metabolite of butyrate, as well as increased the activity of superoxidase in diabetic rats. Furthermore, Banana starch intervention significantly increased the exhaustion time of the diabetic rats, and almost restored it to the normal state of control groups in their swimming and tail suspension tests. Together, our results indicated the modulation of the gut-microbiota-brain axis as a possible mechanism that enables the banana starch diet as a potential therapeutic way for diabetes-associated mood disorders.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42046958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two monoclonal hybridoma cell lines (M8 and M12) that producing mAb with the best sensitivity and specificity were obtained. The obtained mAb-M12 was used to develop an indirect competitive ELISA (icELISA) with 50% inhibition concentrations of 0.15 ng mL−1 and a working range of 0.02–2.74 ng mL−1.

In terms of safety evaluation, both lactates were found to promote cell proliferation and repair. D-lactate was well tolerated for 30 d at doses up to 2000 mg/kg in mice. In terms of immune function evaluation, unexpectedly, D-lactate was found to enhance immunity by increasing the immune organ index, ear swelling index, lymphocyte conversion rate, haemolysis rate and macrophage phagocytosis rate and had a dose-dependent effect. D-lactate showed stronger immune regulation effects than L-lactate. This study proves the safety and the immunoregulation capacity of D-lactate and provides a mechanistic basis for the bioactivity of fermented foods.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45488406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, CZL extracts considerably reduced the generation of reactive oxygen species and nitric oxide in cells. Collectively, CZL extract effectively reduced PM10-induced lung injury by suppressing pulmonary inflammation, potentially due to its anti-inflammatory and antioxidant properties.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41824944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
