Optical microscopy, following crystal violet staining, was used to observe the kinetics of V. parahaemolyticus biofilm formation. The crystal violet-based assay was performed in microtiter plates, and it was employed to determine which factors were most influential in the formation of the biofilms. Colony counting and confocal laser scanning microscopy (CLSM) were used to test the inactivation effect of methylene blue-mediated photodynamic technology on the biofilms. V. parahaemolyticus has the ability to form biofilms, as evidenced by their immediate adherence to glass surfaces and rapid maturity, within 24 h. High (7%) or low (0.5%) salinity was not conducive to the formation of biofilms, and rotational speed greater than 130 rpm also inhibited the process. A 4.05 log reduction in the concentration of viable biofilm cells was obtained with 100 μg/mL methylene blue and 20 min irradiation (24.996 J/cm2), but planktonic cells were more susceptible to the methylene blue-mediated photodynamic reaction (5.46 log reduction). The results presented here show that the methylene blue-mediated PDI technology is an effective means to inactivate V. parahaemolyticus by disrupting its membrane integrity and to inhibit the pathogen’s formation of protective biofilms. This technology is a valid tool that can be used to enhance food safety in the sea food industry.","PeriodicalId":136714,"journal":{"name":"Nutrition and Food Science International Journal","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125393913","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}

This study aims to assess the water needs of some horticultural crops and a fruit tree on the island of São Nicolau, Cape Verde. Twelve crops were selected among the most used by farmers in the area and three scenarios related to precipitation were created. The water needs of the crops in the three scenarios were assessed using the previously calibrated Hargreaves - Samani method. The water balance to determine irrigation consumption was made for the following 3 rainfall conditions: scenario 1 corresponds to the year with the lowest rainfall; scenario 2 is the average of the values recorded over the series; and scenario 3, the year with the highest rainfall. The consumption of water by the crops was not significantly different in the 3 scenarios, the difference being in the amount of water resulting from the precipitation that can be stored and, thus, determining which area can be dedicated to irrigated agriculture. The lettuce, cucumber, pepper and carrot cultures, since the cultures studied were those with the lowest water requirements. The cultivation of banana cultivation should be the subject of a study on its adaptability, due to its high consumption, namely the possibility of applying deficient irrigation in order to increase water productivity.","PeriodicalId":136714,"journal":{"name":"Nutrition and Food Science International Journal","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133123874","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}

We investigated the effect of papaya fruit and leaves on the cell proliferation of Jurkat T-lymphocytic and Daudi B-lymphocytic leukemia cells. Cells were treated with aqueous or methanolic extracts from leaves, skin, pulp, and seeds from green papaya. The papaya fractions were tested for total phenolic content, total flavonoids content, and anti-oxidation activity using chemical assays. Cell proliferation was measured using a WST-1 assay. Our data indicate that methanol and water extracts of seeds and leaves contained higher concentrations of total phenolic compounds and higher anti-oxidation activity than that of extracts from skin and pulp. Both methanol and water extracts from leaves and skin potently inhibited the proliferation of leukemic Jurkat T-cells and Daudi B-cells. However, the effect was more potent on Jurkat T-cells, and the leaf extracts were more effective than that of skin extracts. None of the pulp or seed extracts showed inhibitory activity on leukemic cell proliferation. Although papaya leaves are not consumed as a food, leaf extracts have been used for the treatment of various conditions, including dengue and malaria fevers, gastric ulcers, low platelet counts, and cancers of the breast, lung, and cervix. Our data suggest that the consumption of papaya leaf extracts may also be beneficial in preventing and/or treating lymphocytic cancer. Isolation of active compounds from papaya leaves will also help in developing new drugs for cancer treatment.","PeriodicalId":136714,"journal":{"name":"Nutrition and Food Science International Journal","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125803865","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}
