Diante disso, o presente trabalho buscou avaliar a conservação pós-colheita de folhas da cebolinha, submetidas ao acondicionamento em baixa temperatura. Todo o processamento ocorreu no laboratório do Núcleo de Estudos, Pesquisas e Processamento de Alimentos (NUEPPA) do Centro de Ciências Agrárias (CCA) da Universidade Federal do Piauí, em Teresina, entre agosto e novembro de 2020. Os tratamentos consistiram das análises de amostras retiradas quinzenalmente até o limite de 75 dias, ficando o tratamento testemunha correspondendo às amostras, recém-colhidas, as quais também foram submetidas às determinações de natureza físico-química. Verificações complementares de natureza sensorial foram realizadas, envolvendo cor, aroma e textura, sendo então considerados atributos de qualidade. A refrigeração favoreceu o prolongamento da vida útil da cebolinha, sem variação nas características físico-químicas testadas, demonstrando que é possível conservá-la em refrigerador à baixa temperatura (-20oC) acondicionada em sacos plásticos por, pelo menos 75 dias, sem comprometimento da qualidade do produto; otimizando o aproveitamento da mão de obra familiar, criando as perspectivas de lançamento de um novo produto no rol dos congelados.","PeriodicalId":52402,"journal":{"name":"Journal of Tropical Biodiversity and Biotechnology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89215535","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}

A espécie Ptychosperma macarthurii é uma espécie de valor ornamental e tem sido objeto de estudos sobre o processo de formação de mudas. Portanto, este trabalho teve como objetivo estudar o efeito do armazenamento temporário na germinação de sementes. O delineamento experimental utilizado foi inteiramente casualizado. Para o estudo de armazenamento foram utilizados 7 tratamentos (semeadura logo após a colheita, 1, 2, 3, 4, 5 e 6 semanas após); com 4 repetições de 25 diásporos. Os diásporos foram colocados em caixa de tipo gerbox, contendo vermiculita que ficaram em câmara de germinação a 25°C, já as sementes armazenadas, permaneceram em condições de laboratório. Foram calculados a porcentagem de germinação e o Índice de Velocidade de Germinação e realizada a análise de regressão polinomial. Concluiu-se que a porcentagem de germinação aumentou com o armazenamento atingindo seu maior ponto após 3 semanas de armazenamento, a velocidade de germinação aumentou durante o armazenamento até a quinta semana.","PeriodicalId":52402,"journal":{"name":"Journal of Tropical Biodiversity and Biotechnology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135454659","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}

Combining PGV-1 with natural compounds such as diosmin, galangin, and piperine can enhance its effectiveness due to their promising chemoprevention properties. We aimed to evaluate the effectiveness of combining PGV-1 with diosmin, galangin, or piperine for colon cancer by using in vitro and bioinformatic approaches to predict their target proteins. WiDr cells were used as a model for colon adenocarcinoma (COAD). The cell viability under a single or combination treatment of PGV-1 and diosmin, galangin, or piperine was evaluated using direct counting by the trypan blue exclusion test. SwissTargetProtein, UALCAN, and OncoLnc were utilized to predict target proteins of the compounds in COAD, the expression level of target proteins in COAD, and the survival rate of patients with overexpressed target proteins, respectively. The IC50 values for PGV-1, diosmin, galangin, and piperine were 2.8´10-2 µg/mL, 81 µg/mL, 7 µg/mL, and 172 µg/mL, respectively. All the tested natural compounds showed synergistic effects when combined with PGV-1 at low concentrations. Eleven proteins that were overexpressed in COAD were identified as potential targets. Overlapped predicted targets of PGV-1 and galangin or piperine were CDK1, MET, and TOP2A. The high expression of another set of predicted target proteins, SCD, CA9, and SQLE, led to lower survival rates in COAD patients. We concluded that combinations of PGV-1 with natural compounds can synergistically enhane its anti-cancer activity for colon cancer.","PeriodicalId":52402,"journal":{"name":"Journal of Tropical Biodiversity and Biotechnology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47165255","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}

Hyperlipidemia conditions can increase the risk of atherosclerosis and hypertension. Beetroot (Beta vulgaris L.) is a plant that contains high antioxidants. Beetroot has the potency to be used as a functional food that can reduce the potential for atherosclerosis and blood pressure. The aim of this study was to examine the effect of beetroot-enriched feed on the cholesterol level, atherogenic index and blood pressure of rats (Rattus norvegicus Berkenhout, 1769) induced by high fat and fructose diet. As many as 25 rats were divided into control, hyperlipidemia, and three treatment groups. The hyperlipidemia and treatment groups were induced to become hyperlipidemia using AIN93-M modified high fat and fructose feed for 8 weeks. The treatment groups were followed by intervention with 6, 9, and 12% beetroot enriched feed for 6 weeks. The feed was prepared by mixing beetroot flour in the pellets. Blood pressure, total cholesterol, and HDL level measurement was conducted after hyperlipidemia induction and after the intervention. The data analyzed with one-way ANOVA, DMRT, and T-Test. The results showed that 6% beetroot intervention have the highest increasing of HDL-cholesterol than other groups. The 9% beetroot intervention significantly decrease total cholesterol lower than normal baseline, and 12% beetroot intervention significantly decrease blood pressure than other groups. The atherogenic index of all treatment group was decreased. The 9% beetroot enriched feed was seen as an optimum dose to reduce total cholesterol, atherogenic index and blood pressure and increase HDL-cholesterol.

A total of 15 eels were collected from Pasir Puncu, Keburuhan, Purworejo and Segara Anakan, Cilacap, Indonesia in June 2017, September 2020, and April 2021. The eels were grouped into 4 stages based on the silvering stage and sex, namely: yellow undifferentiated, yellow female, silver male, and silver female. The average length and body weight of yellow undifferentiated eels were 255.07 ± 45.91 mm and 13.66 ± 8.5 g, respectively; for yellow female, the values were 374.35 ± 41.51 mm and 56.5 ± 12.02 g; for silver male, the values were 432.43 ± 15.15 mm and 140.29 ± 13.85 g; and for silver female were 702 ± 0.00 mm and 545 ± 11.31 g. The present study successfully recorded the histological structure of the swim bladder of A. bicolor bicolor in silver male and silver female stages. Silver males and females displayed a greater significant development of the swim bladder than yellow stages in the gas gland, mucosa, and submucosa layers. These results suggest that an increase in the gas gland thickness allows a greater contribution from gas to gas secretion, the mucosa exerts a mechanical effect on the newly formed gas bubbles, and the submucosa thickness reduces gas conductivity from the swim bladder wall.

Experimental validation was done using qPCR for optimal annealing temperature, priming ability, and amplificon specificity, and electrophoresis for product length validation. This assessment resulted in in silico and laboratory experimental validation of Acta2, Fap, Hprt1, Pdgfb, Pik3r1, and Vcam1 primer pairs producing suitable amplicon for qPCR using Rattus norvegicus cDNA with SYBR annealing temperature range of 60-65°C with three mM MgCl2.
