Botrytis cinerea is one of the most important phytopathogenic fungi causes postharvest losses in fruits and vegetables. To verify the possibility of using piperine as a botanical fungicide against B. cinerea, we determined the in vivo and in vitro antifungal activity of piperine against B. cinerea and investigated its antifungal mechanism effects on the mycelial surface, membrane integrity, soluble protein content, superoxide dismutase, catalase, succinate dehydrogenase and the malondialdehyde content of B. cinerea. The in vitro antifungal activity assay indicated that the EC50 value of piperine against B. cinerea was 58.66 μg/mL and the in vivo antifungal assay showed that piperine at 400 μg/mL suppressed 93.88% growth of B. cinerea on Lycopersic esculentum. The antifungal mechanism assay showed that piperine could inhibit mycelial growth of B. cinerea by reducing antioxidant activity, inhibiting the tricarboxylic acid pathway, and lysing the cell membrane. All these results indicated that piperine as a natural component has the potential to control B. cinerea and can be considered as a botanical fungicide for postharvest disease control of gray mold.","PeriodicalId":9884,"journal":{"name":"Chiang Mai Journal of Science","volume":"45 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73790148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, there is no effective treatment specific to DENV infection, in addition, the efficiencies of the vaccines are not fully effective against all four circulating DENV serotypes. Therefore, the development of an anti-viral agent to combat DENV infection and lower the risk of disease progression is needed, especially in the endemic area. This study investigated the effect of Terminalia bellirica extract and its combination with alpha-mangostin (α-MG) in lowering the DENV serotype 2 infection in Vero cells and A549 lung adenocarcinoma cells. The phytochemical characterization of T. bellirica extract demonstrated that T. bellirica extract contained a total phenolic compound of 198.29 ± 15.95 mg gallic acid/g extract in which the gallic acid was the major bioactive compound, judged by HPLC. Treatment with 50 μg/mL of T. bellirica extract caused over 50% of DENV envelope protein reduction in Vero cells and showed no significant attenuation upon the six rounds of thermal stress exposures. At an equal concentration, the efficiency of T. bellirica extract in A549 cells was lower than that of Vero cells; however, combination with low-dose α-MG (0.5-2 μg/mL) showed to significantly improve the inhibitory activity of T. bellirica extract. This study demonstrated the great stability of T. bellirica extract to inhibit DENV infection and suggested a combination approach with α-MG offered protection against the DENV tissue tropism.","PeriodicalId":9884,"journal":{"name":"Chiang Mai Journal of Science","volume":"17 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72871665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MoS2 exhibits a thickness-dependent band gap that changes from indirect band gap of ~1.3 eV for bulk MoS2 to direct band gap of ~1.9 eV in monolayer form. Such indirect-to-direct gap transition due to quantum confi nement results in giant enhancement in photoluminescence quantum yield. Recent study demonstrated that the co-existence of 2H- and 1T-MoS2 synthesized by hydrothermal method exhibited superior electronic conductivity to those with 2H semiconducting phase. Metallic 1T phase of MoS2 is attracting much attention due to its high electronic conductivity and potential applications in supercapacitors, thermoelectric energy harvesting, and memristors. In this paper, we investigated a hybrid structure between 2H and 1T of MoS2 by a hydrothermal process and investigated its optical property via photoluminescence spectra with changes in pH values. Our results indicated that photoluminescence occurred in the visible light region and the band gap was determined to be ~1.96–2.50 eV. In addition, pH of the precursor solution strongly affected the fi nal structure of MoS2 nanocrystals, which in turn, affected their photoluminescence property wherein pH = 4–5 was identifi ed as optimum for 2H–1T-MoS2 synthesis.","PeriodicalId":9884,"journal":{"name":"Chiang Mai Journal of Science","volume":"19 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87000042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the finite element results as samples, support vector regression (SVR), back propagation (BP) neural network and extreme learning machine (ELM) were used to establish the prediction model of the relationship between BTLR and four structural parameters. The accuracy and applicability of three prediction models were compared and analyzed. The results showed that SVR algorithm has higher prediction accuracy and stability compared with other algorithms for the prediction of BTLR. The mean square error and determination coefficient of its test set are 0.00059637 and 0.99253 respectively. After that, SVR results were taken as samples of genetic algorithm to find the combination of structural parameters with the minimum BTLR. The obtained structural parameters were combined for simulation modeling calculation. Its results showed that the fluid velocity in the blade tip region is significantly reduced and the velocity transition is gentle. The difference between simulation and optimization was 0.01%. This method innovatively applies machine learning algorithm to the prediction of BTLR, and improves the problem of low speed and high cost when only using finite element method.
