Organizational identifiers in the portuguese scientific ecosystem: the transiti...
Harb-Anger, Talissa; Melo-Dias, Sara; Laranjeira, Cátia; Lopes, Pedro Leitão; Moreira, João MendesOpen Science has driven significant changes in the management and sharing of scientific information. In Portugal, the PTCRIS program plays a central role in implementing national and European policies, promoting interoperability through persistent identifiers. Since 2016, the ISNI+ system, which combines the ISNI infrastructure with commercial services from CCC – Ringgold Solutions, has been used to identify or...

Lopes, Paulo; Graça, Paulo; Laranjeira, Cátia; Ribeiro, Fernando; Truta, Raquel; Saraiva, RicardoA rede de repositórios RCAAP é uma infraestrutura crucial para a promoção da Ciência Aberta em Portugal. Esta infraestrutura incluí um serviço de alojamento de repositórios institucionais (SARI) que aloja 28 repositórios. Com o desenvolvimento e disponibilização da versão 7 do software para repositórios (DSpace) e o fim anunciado do suporte para as versões anteriores, a equipa RCAAP cedo iniciou um plano para a...
Development of Plan S monitoring and compliance tool in the context of PTCRIS f...
Mendes Moreira, João; Pardelha, Filipa; Laranjeira, Cátia; Pereira, Filipa; Novais, Joana; Lopes, Paulo Simões; Antunes, António; Cardoso, ElsaThe Portuguese Foundation for Science and Technology (FCT) has endorsed Plan-S since early 2021 and it is working towards implementing its obligations. To ensure an effective fulfillment of its open science policies, FCT is implementing a new monitoring and compliance tool, that will enforce the compliance with Plan-S as well as the new FCT’s open access (OA) policy. This paper details FCT’s approach to impleme...
Phytochemical screening of aqueous and hydroalcoholic extractive solutions of T...
Laranjeira, Cátia; Oliveira, Ana Isabel; Ferraz Oliveira, Rita; Cruz, Agostinho; Pinho, CláudiaPlants of the genus Taraxacum (dandelion) are a source of diverse phytochemicals, and its biological activities can be exploited in different areas of human health. Phytochemical composition of dandelion, in particular T. officinale, has been extensively studied over the years. However, to date no studies have been performed regarding T. hispanicum phytochemical characterization, which is a common South Europea...
Influence of solvent type, extraction techniques, particle size, extraction tim...
Laranjeira, Cátia; Oliveira, Ana Isabel; Ferraz Oliveira, Rita; Cruz, Agostinho; Pinho, CláudiaPlants of the genus Taraxacum have been used for years in medicine and food. This genus, with a complex taxonomy, includes some species of difficult distinction, where T. hispanicum is included. The leaves of these plants, known as dandelion, continue to be used as infusions, ethanolic extracts, or as juice. Since the plant represents an important source of pharmacologically active molecules, namely antioxidant...
Centrosome amplification arises before neoplasia and increases upon p53 loss in...
Lopes, Carla A.M.; Mesquita, Marta; Cunha, Ana Isabel; Cardoso, Joana; Carapeta, Sara; Laranjeira, Cátia; Pinto, António E.; Pereira-Leal, José B.Centrosome abnormalities are a typical hallmark of human cancers. However, the origin and dynamics of such abnormalities in human cancer are not known. In this study, we examined centrosomes in Barrett's esophagus tumorigenesis, a well-characterized multistep pathway of progression, from the premalignant condition to the metastatic disease. This human cancer model allows the study of sequential steps of progres...
