Estudo prévio da Quinta Biológica no Parque Ecológico do Funchal
Teixeira, Dora Valentina FlorençaA presente dissertação pretende demonstrar que a problemática da sustentabilidade pode ser minimizada com pequenos gestos. O desafio é imprimir mudanças à maneira como temos vivido até ao momento, de como gerimos os recursos, de como é feita a distribuição de custos e benefícios e de que forma tudo isto se reflete na natureza, no meio onde nos inserimos e na qualidade de vida das sociedades contemporâneas e fut...
Pigment analysis of Portuguese portrait miniatures of 17th and 18th centuries ...
Ginja Teixeira, Jorge; Martins Teixeira, Dora; Mirão, José; Candeias, António J.; Simões Rodrigues, Paulo; Veiga, AlfredinaSeventeen Portuguese miniature portraits on copper support from the Évora Museum collection (Portugal) were analyzed in situ and nondestructively by Raman microscopy (RM), SEM-EDS, and stereomicroscopy. This work constitutes a great breakthrough in the study of miniature paintings from the 17th and 18th centuries, since the chemical information known about this unique kind of paintings are still scarce, and in ...
Electro-oxidation of carbamazepine metabolites: Characterization and influence ...
Ginja Teixeira, Jorge; Veiga, Alfredina; Palace Carvalho, Alfredo J.; Martins Teixeira, DoraAbstract The electro-oxidation behavior of five important metabolites of carbamazepine (CBZ) and their potential influence on the voltammetric determination of the parent drug in biological fluids was investigated for the first time. This investigation was performed using cyclic voltammetry, in combination with controlled potential electrolysis and HPLC-DAD-MS analysis of oxidation products of these compounds....
O-coumaric acid ester, a potential early signaling molecule in Pinus pinea and ...
Ragonezi, Carla; Teixeira, Dora; Caldeira, Ana Teresa; Martins, Maria do Rosário; Santos Silva, Celeste; Ganhão, Elsa; Klimaszewska, KrystynaDuring ectomycorrhizal (ECM) establishment, biochemical signals lead to the development of complex structures in both the plant and the fungus that ultimately result in the formation of an ectomycorrhiza. The cross-talk between partners begins before physical contact. Our objective was to investigate the chemical nature of the signals during the first stages of in vitro mycorrhization of Pinus pinea with Pisoli...

Study on the use of Typha spp. for the phytotreatment of water contaminated wit...
Dordio, Ana; Ferro, Raquel; Teixeira, Dora; Palace, Alfredo J.; Pinto, Ana P.; Dias, Cristina M.B.Several studies on phytotoxic effects caused by organic xenobiotics and their removal from water by macrophytes have already been performed to evaluate the usefulness of these plants for phytoremediation technologies. In this context, a study was conducted to assess Typha spp.’s ability to withstand and remove, from water, the non-steroidal anti-inflammatory drug ibuprofen. For an initial ibuprofen concentratio...

Chemical composition and anti-diabetic properties of Cytisus multiflorus
Vieira, Ines P.; Costa, Ana Rodrigues; Teixeira, Dora M.; Antunes, Celia M.; Cruz-Morais, JulioBakground and aims: The interest on plants with potential medicinal properties has been increasing worldwide. In the Iberian Peninsula there are some endemic species known by the population for their pharmacologic activity with valorization potential that have not been yet characterized. The white Spanish broom (Cytisus multiflorus) is described as having anti-diabetic effect [1] and in a preliminary the hypogl...
