Tea and herbal infusions consumption in Portugal: consumer behaviors
Sousa, A. C.; Ribeiro, C.; Gonçalves, V. M. F.; Pádua, I.; Leal, S.Background: Tea and herbal infusions (THIs) consumption is recognized for its beneficial effects, which are attributed to the antioxidant properties of phenolic compounds [1–3].The wide diversity of THIs available in market and the absence or failure in quality control can expose the population to health risks [3]. Moreover, uncontrolled consumption may cause toxicity or lack of the expected benefits. Therefore...
Evaluation of the systemic oxidative stress status upon in vivo exposure to tra...
Cardoso, C.; Dinis-Oliveira, R. J.; Leal, S.; Barbosa, J.; Faria, J.Background: Tramadol and tapentadol are synthetic centrally acting analgesic opioids, used in the treatment of moderate to severe pain [1]. Despite their optimized therapeutic and safety profiles, these compounds are associated with adverse effects, namely CNS and respiratory depression, abuse and dependence [2, 3]. Oxidative stress is one of the main toxicity mechanisms triggered by opioids [1, 4, 5]. Objectiv...
Construção de uma metodologia de avaliação da importância das soft skills na in...
Vaz, L.; Franco, V.; Leal, S.As soft skills são competências não técnicas que influenciam o sucesso laboral. A sua importância é cada vez mais destacada no mundo organizacional, pois contribuem significativamente para o bom desempenho e o desenvolvimento do percurso profissional. Verifica-se, no entanto, uma lacuna no que concerne ao seu estudo nas profissões que envolvem uma relação de ajuda, como no caso da Intervenção Precoce na Infânci...
Attitudes and HRM decisions toward older workers in Africa: Exploring contradic...
Rego, A.; Vitória, A.; Ribeiro, T.; Ribeiro, L.; Lourenço-Gil, R.; Leal, S.; Cunha, M. P. e.We explored the attitudes toward older workers of African versus Portuguese managers, and how these managers make HRM decisions in scenarios involving younger versus older workers. To make cultural, social, and institutional explanations more robust, we also included two samples of students attending Portuguese universities: one sample comprising African students, the other comprising Portuguese ones. The main ...
Hydrophobic modification of bacterial cellulose using oxygen plasma treatment a...
Leal, S.; Cristelo, C.; Silvestre, Sara; Fortunato, Elvira; Sousa, Aureliana; Alves, A.; Correia, Daniela Maria Silva; Lanceros-Méndez, S.; Gama, F. M.A new strategy for the surface modification of bacterial cellulose (BC) through the combination of oxygen plasma deposition and silanization with trichloromethyl silane (TCMS) is described. The combined use of the two techniques modifies both the surface roughness and energy and therefore maximizes the obtained hydrophobic effect. These modified membranes were characterized by Scanning Electron Microscopy (SEM)...

Development of a water-soluble dextrin-amphotericin B conjugate for the treatme...
Fidalgo, João; Silva-Carvalho, Ricardo; Leal, S.; Cruz, T.; Tomás, A. M.; Parpot, Pier; Gama, F. M.Leishmaniasis is a life-threatening disease with a worldwide distribution and a huge impact especially in immunocompromised patients. Nowadays, the use of amphotericin B, an antifungal agent, or other marketed strategies to overcome this disease exhibit major clinical limitations. Thus, other strategies have been pursued to achieve better clinical treatments and decrease toxicity. In this work, a promising conj...

Assessment of the potential reactivity of granitic rocks — Petrography and expa...
Ramos, V.; Fernandes, I.; Santos Silva, A.; Soares, D.; Fournier, B.; Leal, S.; Noronha, F.Granite is one of the most commonly employed materials in the production of aggregates for concrete, and represents 40% of the total volume of aggregates produced in Portugal. This type of rock is traditionally considered as slowly/late reactive or even non-reactive to alkalis. However, a number of cases of damaged concrete structures in Portugal, due to alkali–silica reaction, have been related to granitic agg...
MycoMix and risk assessment: a contribute to improve risk analysis
Alvito, Paula; Assunção, Ricardo; Borges, T.; Dupont, D.; Leal, S.; Loureiro, S.; Louro, H.; Martins, Carla; Nunes, Baltazar; Pinhão, M.Risk analysis, is a powerful tool for including science-based knowledge in a systematic approach to food safety problems. The use of risk analysis can promote ongoing improvements in public health and provide a basis for expanding international trade in foods. Within risk analysis, the risk assessment results are quantitative or qualitative expressions of the likelihood of harmful effects associated with exposu...
