Roadmap for the development of EnLang4All: A video game for learning English
Alexandre, I.; Lopes, P. F.; Borges, C.Nowadays, people are more predisposed to being self-taught due to the availability of online information. With digitalization, information appears not only in its conventional state, as blogs, articles, newspapers, or e-books, but also in more interactive and enticing ways. Video games have become a transmission vehicle for information and knowledge, but they require specific treatment in respect of their prese...
Use of dirty plastic waste as precursors for activated carbon production – a co...
Cansado, I.P.P.; Mourão, P.A.M.; Nabais, J.M.V.; Tita, B.; Batista, T.; Rocha, T.; Borges, C.; Matos, G.The production of activated carbons (ACs) from dirty plastic wastes derived from the mechanical/biological treatment of urban solid wastes, disposable plastics and plastics used in agriculture is reported. The use of these precursors is innovative and contributes to the circular economy by the valorization of dirty plastics that are usually disposed in landfills. ACs were produced by physical activation, with a...
Dealing with plastic waste from agriculture activity
Batista, T.; Cansado, I.P.P.; Tita, B.; Ilhéu, A.; Metrogos, L.; Mourão, P.A.M.; Nabais, J.M.V.; Castanheiro, J.E.; Borges, C.; Matos, G.The increase in agricultural production and food quality has forced the growing useof plastics in various activities. The plastic wastes are partially recycled in or outside Portugal;nevertheless, the contaminated wastes are sent to landfill. It is crucial to consider new models fortheir valorization at a regional level and from a circular economy perspective. In the scope of the Placarv õ es project, a study wa...
Study of antioxidant and antitumoral activity of cork processing wastewaters co...
Gomes, Luís; Borges, C.; Serralheiro, M.L.M.; Pacheco, Rita; Minhalma, MiguelCork processing wastewater present a severe environmental problem due to its high content in organic matter, such as sugars and non-biodegradable compounds like polyphenols (PPs), namely tannins. In this work, the assessment of the biological activity and identification of valuable polyphenolic compounds was envisaged. These compounds were obtained using membrane technology, leading to the valorisation of the w...
Alimentação Vegetariana em Idade Escolar
Pinho, J.P.; Silva, S.G.; Borges, C.; Santos, Cristina; Santos, Alejandro; Antonio Guerra; Graça, PedroInfancy and adolescence are periods of rapid physical growth and cognitive development, as well as of acquisition of social and behavioural skills. During these periods, appropriate food intake is needed for each age group in order to ensure adequate growth and a good health condition. Nutritional needs of children and adolescents are different from those of adults and they change as the development process tak...
New In Vitro studies on the bioprofile of Genista tenera antihyperglycemic extract
Batista, D.; Falé, P.L.; Serralheiro, M.L.; Araújo, M.E.; Madeira, P.J.A.; Borges, C.; Torgal, Isabel; Goulart, Margarida; Justino, Jorge; Martins, A.The inhibition of a-glucosidase and glucose-6-phosphatase, two enzymes involved in the carbohydrate metabolism, is an important target to control glycaemia on individuals with type 2 diabetes. In this work we report for the first time the inhibition of both enzymes by the antihyperglycemic n-butanol extract from Genista tenera (Fabaceae). This extract decreased a-glucosidase and glucose-6-phosphatase activities...
Study of sardine oil antioxidant anti-inflammatory properties for the developme...
Borges, C.In Portugal sardine fishery is one of the oldest and the most important pelagic resource from Portuguese mainland, both economically and socially. The sardines have important nutritional characteristics, being an excellent source of vitamins, proteins, lipids and minerals with proven benefits for human health, being rich in ω-3-PUFAs, namely, EPA and DHA. Studies reported that there is a direct link between a d...
Delivery of cytarabine by pegylated liposomes for efficient, long-term anticanc...
Sárria, M. P.; Nogueira, Eugénia; Oliveira, A.; Matamá, Maria Teresa; Guimarães, Diana Isabel Pereira; Borges, C.; Cavaco-Paulo, Artur; Gomes, Andreia CThe cytosine arabinoside cytarabine is an effective marine-derived antineoplastic agent for the treatment of acute myelogrnous and lymphocytic leukemias. As this nucleoside antimetabolite is an S-phase-specific drug, prolonged exposure of cells to toxic concentrations is critical to achieve maximum biological effect. The activity of cytarabine is nevertheless decreased by its rapid deamination to the biological...
Study of sardine oil antioxidant properties for the development of topical ther...
Borges, C.; Ribeiro, Artur J.; Carvalho, A. C.; Sousa, F.; Oliveira, I.; Batista, I.; Bandarra, N. M.; Gomes, Andreia C; Paulo, Artur CavacoSardine is one of the most common fish of the Portuguese coast with important nutritional features. Sardine oil is also a natural source of nutrients with proven benefits for human health, being rich in omega-3 fatty acids, particularly EPA and DHA (polyunsaturated fatty acids-PUFAs) [1]. Several studies show that there is a direct link between a diet enriched in omega-3 and the prevention of diseases such as c...
Controlo estatístico de qualidade em ensaios interlaboratoriais - caso particul...
Carinhas, Dora; Borges, C.; Silva, Pilar; Infante, PauloDevido à grande concorrência no mercado nacional e internacional, os laboratórios procuram a garantia dos seus ensaios. A participação em ensaios de comparação interlaboratorial permite evidenciar a competência de um laboratório através da avaliação do seu desempenho. Neste contexto, a aplicação de ferramentas estatísticas que permitam aumentar a fiabilidade dos resultados assume um papel muito importante. Nest...
