Pereira, Zélia; Matos, João Xavier; Solá, A. Rita; Batista, Maria Joao; Salgueiro, Rute; Rosa, Carlos J. P.; Albardeiro, Luis; Mendes, MárciaABSTRACT: The recently discovered massive and stockwork sulphide mineralization of Semblana-Rosa Magra and Monte Branco, situated ESE of the Neves–Corvo volcanogenic massive sulphide (VMS) deposit in the Iberian Pyrite Belt (IPB) is presented. Geological setting and tectonic model is discussed based on proxies such as palynostratigraphy and U–Pb zircon geochronology. The mineralization is found within the IPB V...

Health-promoting effects of Thymus herba-barona, Thymus pseudolanuginosus, and ...
Afonso, Andrea Luísa Fernandes; Pereira, Olívia R.; Neto, Rodrigo; Silva, Artur; Cardoso, Susana M.Thymus herba-barona, Thymus pseudolanuginosus, and Thymus caespititius decoctions were screened for their phenolic constituents, along with their potential antioxidant, anti-inflammatory, and antibacterial activities. The total phenolic compounds in the extracts of the three plants ranged from 236.0 ± 26.6 mgGAE/g (T. caespititus) to 293.0 ± 30.5 mgGAE/g of extract (T. pseudolanuginosus), being particularly ric...
Impact of magnetic nanofillers in the swelling and release properties of k-carr...
Daniel-da-Silva, Ana L.; Moreira, Joana; Neto, Rodrigo; Estrada, Ana C.; Gil, Ana M.; Trindade, TitoNatural polysaccharides such as -carrageenan are an important class of biomaterials for drug delivery. The incorporation of magnetic nanoparticles in polysaccharide hydrogels is currently being explored as a strategy to confer to the hydrogels novel functionalities valuable for specific bio-applications. Within this context, -carrageenan magnetic hydrogel nanocomposites have been prepared and the effect of magn...
