Quem Semeia Cocriação de Personas Ligadas ao VIH e SIDA Colhe Literacia em Saúd...
Vaz de Almeida, Cristina; Correia, Ana; Ferreira, Andreia Pinto; Santos, Catarina Esteves; Mora, Cristina; Sousa, Cristina; Trigo, DivaA problemática do vírus da imunodeficiência humana (VIH) e síndrome de imunodeficiência adquirida (SIDA) está geralmente confinada a uma perspetiva biomédica. São poucos os casos de investigação sobre a participação das entidades com peso na intervenção comunitária, como as associações de cariz comunitário que apoiam pessoas que vivem com VIH e SIDA. O estudo apresentado foca-se no projeto português VIHVER, que...
Metabolomics Connecting Genomes and Phenomes in Plant Molecular Breeding—A Spec...
Rodrigues, Lénia; Estêvão, Catarina; Garcia, Raquel; Rato, Ana Elisa; Campos, Catarina; Marques, Mónica; Pires, Rita; Peixe, Agusto; Cardoso, HéliaThe interest in Mediterranean species has grown exponentially in recent decades, driven by their distinctive organoleptic properties and the high content of bioactive compounds beneficial to human health. This study presents a comprehensive review of current knowledge on the alterations in metabolomic profiles associated with the biosynthesis of functional metabolites in response to abiotic stressors, namely sa...
Establishment of a Protocol for the Characterization of Secreted Biomolecules i...
Pires, Rita; Rodrigues, Lénia; Santos, Fátima; Duarte, Iola; Ciordia, Sérgio; Peixe, Augusto; Cardoso, HéliaSomatic embryogenesis (SE) involves the formation of embryo-like structures from somatic cells without fertilization and is widely used for clonal propagation and genetic transformation. However, in olive (Olea europaea sp. europaea), SE remains challenging due to the recalcitrant behavior of adult tissues when used as initial explants. Bioactive molecules released into the culture medium (conditioned medium, C...
Exploring the involvement of the somatic embryogenesis receptor kinase (SERK) g...
Pires, Rita; Marques, Diogo; Campos, Catarina; Peixe, Augusto; Cardoso, HéliaSeveral Portuguese olive tree cultivars are characterized by their high-quality oils, which explains their use on the production of DOP (Denomination of Protect Origin) olive oil brands. However, some of those cultivars are affected by serious agronomic problems, including high susceptibility to biotic and abiotic stresses, excessive vigour, and low ability to adventitious root formation, which strongly limits ...
Indução e manutenção de embriogénese somática a partir de embriões zigóticos ma...
Pires, Rita; Cardoso, Hélia; Ribeiro, Augusto; Cordeiro, António; Peixe, AugustoAlgumas variedades de oliveiras portuguesas, caracterizadas pelos seus azeites de alta qualidade, apresentam diversos problemas agronómicos como o vigor excessivo, a alta suscetibilidade a stresses bióticos e abióticos e a baixa capacidade de propagação. Estas variedades, entre as quais se encontra a ‘Galega vulgar’, são fortes candidatas a programas de melhoramento baseados em novas tecnologias, com o objetivo...
Unraveling somatic embryogenesis signaling pathways – the role of extracellular...
Pires, Rita; Peixe, Augusto; Santos, Fátima; Cardoso, HéliaSomatic embryogenesis (SE) can be described as a process involving the formation of structures similar to the zygotic embryos, arising from dedifferentiation of somatic cells and not requiring the occurrence of fertilization. This process, widely used in clonal propagation and genetic transformation of several plant species, is not routinely used in olive (Olea europaea sp. europaea L.), due to the recalcitrant...

Pires, Rita; Cardoso, Hélia; Ribeiro, Augusto; Cordeiro, António; Peixe, AugustoAlgumas cultivares de oliveiras Portuguesas caracterizam-se pela produção de azeites de alta qualidade, mas apresentam diversos problemas agronómicos de entre os quais se destacam, um vigor excessivo, alta suscetibilidade a stresses bióticos e abióticos e baixa capacidade de enraizamento por estacaria. Isto torna-as fortes candidatas a programas de melhoramento baseados em ferramentas de engenharia genética. O ...
In Vitro Establishment and Maintenance of Culture Lines with Differentiated Som...
Pires, Rita; Cardoso, Hélia; Rodrigues, Lénia; Peixe, AugustoSomatic embryogenesis (SE) is a powerful biotechnological tool for large-scale clonal plant propagation. However, most woody species exhibit a recalcitrant response. Olea europaea L., a highly valuable tree crop, is among these recalcitrant species. Unravelling the molecular mechanisms underlying SE efficiency in O. europaea is, therefore, essential. Access to embryogenic lines with contrasting capacities for s...
The conception of stories as a stories for piano teaching and learning: Relatio...
Pires, Rita; Castilho, M.L.C.The relation between music and emotions has been a topic of several studies in the last two decades. We tried to find strategies that would help encourage students on piano learning, especially the youngest ones. The strategy of finding relationships between musical elements and extra-musical elements can be a way to emotionally involve the students in the music. In an experiment, we asked two twelve year old p...
Microalgae as a selenium vehicle for nutrition: a review
Pires, Rita; Costa, Margarida; Pereira, Hugo; Cardoso, Helena; Ferreira, Luís; Lapa, Nuno; Silva, Joana; Ventura, MárciaSelenium (Se) is essential for human and animal nutrition, playing a key role in antioxidant and immune functions. Organic Se is better for supplementation because it is more efficiently assimilated and less toxic than its inorganic form. Due to the scarcity of Se in European soils, supplementation in feed and food is necessary. Currently, inorganic Se (sodium selenite and selenate) and organic Se in Se-enriche...
