Depois de o modelo da democratização da cultura ter sido a principal orientação das políticas culturais no Portugal democrático, o modelo da democracia cultural começa a surgir em alguns discursos políticos e documentos, como a Carta do Porto Santo, com a influência do instrumento político designado Plano Nacional das Artes, que é desenvolvido pelos Ministérios da Cultura e da Educação. O presente texto apresen...
Introduction: The demographic evolution in Portugal is characterized by a marked population aging, with high levels of dependency associated, representing an enormous challenge for families that include dependent people in the household. It is important to identify the resources and equipment that facilitate self-care used by families who care for these people. Methodology: Study cross-sectional and described d...
This paper investigates the complex interrelation between economic indicators, such as inflation and government spending, and their consequences for public health and suicide rates. Scholars and policymakers are increasingly focused on understanding how economic volatility affects individuals’ resource access and stress levels, thus influencing societal well-being. This study analyzes data from three public dat...
First described in 2018, heterozygous variants of the RHOBTB2 gene, affect the translation of a Rho GTPase protein, essential in neuronal development and synaptic plasticity. The few cases described are characterized by a clinical spectrum of epileptic encephalopathy, psychomotor and cognitive delay, microcephaly, nonspecific facial dysmorphism and movement disorder. We report a case of a female child, who had ...
O presente texto visa apresentar e refletir sobre os pontos fortes e os limites da prosopografia, tendo em conta as suas vantagens e desafios. O artigo não pretende, assim, discutir, como outros autores têm apontado, se a prosopografia é uma técnica, um método, uma metodologia ou uma ciência exata, mas, antes, compreender como avaliar a sua utilização. Através de uma revisão bibliográfica, compreendemos que é m...
Microplastics are present in all parts of the ocean and can have deleterious effects on marine resources. The aim of this work was to map the presence of microplastics in commercial marine species such as bivalves (mussels Mytilus galloprovincialis and clams Scrobicularia plana), crabs (Carcinus maenas) as well as fish (Mullus surmuletus) to relate microplastics levels to pollution sources, assess possible impa...
Recently isolated microalgae Tetraselmis sp. IMP3, Tetraselmis sp. CTP4, and Skeletonema sp. were studied. The three novel strains contained relatively high levels of polyunsaturated fatty acids (PUFA) and n3 PUFA. However, highly unsaturated n3 FA contents were relatively low (5.7-13.0% of the total FA). In general, eicosapentaenoic acid (EPA, 20:5 n3) contents were low (< 6.4% of the total FA). However, in Sk...
Com este estudo foi nosso propósito pesquisar de que modo é que os familiares/ pais de um grupo de crianças de escolas de Jardim de Infância e de 1.º Ciclo do Ensino Básico (1.º CEB) e, respetivos educadores de infância/ professores do 1.º CEB, percecionam o papel que essa instituição tem na promoção de hábitos de vida saudável dos seus educandos, no que respeita ao seu contributo para uma melhor educação alime...
Potential toxic effects of Ag NPs ingested through the food web and depending on the season have not been addressed in marine bivalves. This work aimed to assess differences in protein expression in the digestive gland of female mussels after dietary exposure to Ag NPs in autumn and spring. Mussels were fed daily with microalgae previously exposed for 24 hours to 10 µg/L of PVP/PEI coated 5 nm Ag NPs. After 21 ...
In this study, the acute toxicity of microplastics (MPs) on unicellular organisms as marine decomposers and microalgae was assessed, by evaluating standards endpoints included in International Standard Organization (ISO) protocols. The bacteria Vibrio fischeri and the diatom Phaeodactylum tricornutum were exposed to different sizes (1-500 μm) of polyethylene MPs in order to evaluate bioluminescence inhibition a...
