Optimized metrological and geochemical assessment of trends in estuarine and oc...
Borges, CarlosThe evaluation of the environmental status and evolution of an ecosystem is a crucial element to support decision-makers in their management. Such evaluation must incorporate the uncertainty of collected information to allow their objective and binding interpretation. However, up to now, there were no tools for the objective interpretation of environmental monitoring data that consider system heterogeneity and ...
Potential for coastal and offshore aquaculture in Portugal: Insights from physi...
Mosqueira, Miguel; Pombo, Ana; Borges, Carlos; Brito, Ana C.; Zacarias, Nuno; Esteves, Rita; Palma, CarlaPhysico-chemical and biological parameters along the Portuguese coast were analyzed to evaluate the potential to produce aquatic species of economic interest. Water samples were collected in 2018 and 2019 in five different areas of the Portuguese coast. Currents data were collected between 2018 and 2020 and historical waves height data from 1988 to 2019. According to the results, there is a wide variety of spec...
Cork processing wastewaters components fractioned by ultrafiltration membranes–s...
Gomes, Luís; Borges, Carlos; Serralheiro, Maria Luisa; Minhalma, Miguel; Pacheco, RitaBACKGROUND: Cork processing wastewater is an environmental problem due to its high content of organic matter, such as sugars and non-biodegradable compounds such as polyphenols (PPs), namely tannins. Membrane technology aimed at valorisation of the wastewaters components, concentrate stream, and simultaneously offer a pre-treatment of the wastewater, permeate stream. In this work, the identification of bioactiv...
Bioactivities of decoctions from Plectranthus species related to their traditio...
Brito, Elsa; Gomes, Emma; Fale, Pedro; Borges, Carlos; Pacheco, Rita; Teixeira, Vítor; Machuqueiro, Miguel; Ascensão, Lia; Serralheiro, Maria LuisaEthnopharmacological relevance Decoctions of Plectranthus species are traditionally ingested after large meals for treatment of food digestion and alcohol abuse. Aim of the study This study aims at associating the digestion-related ethno-uses of Plectranthus species decoctions to molecular mechanism that might explain them: easing digestion (AChE inhibition) and treating hangover (ADH inhibition) Material and m...
Metodologias de investigação comuns nas ciências sociais: Possíveis contributos...
Borges, Carlos; Furtado, Gonçalo; Oliveira, JoanaEste artigo expõe metodologias de investigação científica, enquanto potenciais contributos para o conhecimento de sujeitos em planeamento arquitetónico e urbanístico. Entende-se que a investigação em arquitetura e urbanismo não está pautada por metodologias únicas e claras, parecendo ser múltiplas as metodologias que permitem desenvolver teorias com as quais arquitetos e urbanistas sustentam as suas conceções. ...

Water column characterisation on the Azores platform and at the sea mounts sout...
Palma, Carla; Lillebø, Ana I.; Borges, Carlos; Souto, Miguel; Pereira, Eduarda; Duarte, Armando C.; Abreu, Manuel Pinto deThis study provides data concerning the hydrography and water chemistry of the Atlantic region between 29-38° N and 27-31° W, and establishes background values for dissolved Cu, Cd, Pb and As. Three water masses were identified: the Eastern North Atlantic Central Water (ENACW), the Mediterranean Water (MW) and the North Atlantic Deep Water (NADW). The ENACW exhibits a clear meridional gradient of temperature an...
Bioactivity studies and chemical profile of the antidiabetic plant Genista tenera
Rauter, Amelia P.; Martins, Alice; Lopes, Rui; Ferreira, Joana; Serralheiro, Luisa M.; Araujo, Maria-Eduarda; Borges, Carlos; Justino, JorgeAim of the study: Genista tenera is a plant endemic to the island of Madeira and is used in folk medicine to control diabetes. In the present work we evaluate the anti hyperglycaemic activity of its n-butanol extract and determine its chromatographic prof. - The British Council and the Ministerio da Ciencia e do Ensino Superior ; Fundacao para a Ciencia e Tecnologia ; Thermo Finnigan's ; Analytical Chemistry Tr...
The opposing effects of the flavonoids isoquercitrin and sissotrin, isolated fr...
Paulo, Alexandra; Martins, Sofia; Branco, Pedro; Dias, Teresa; Borges, Carlos; Rodrigues, Ana Isabel; Costa, Maria do Ceu; Teixeira, AdrianoThe effect of an aqueous extract of Pterospartum tridentatum on the blood glucose levels of normal Wistar rats was investigated in a situation of oral glucose challenge. The extract at 300 mg/kg showed an anti-hyperglycaemic effect in the first 30 min aft
Electron Ionization Mass Spectrometric Study of Some Substituted 1,3-oxazoles
Salgueiro, Pedro; Dias, Catarina; Carreiras, M. Carmo; Borges, CarlosHeterocyclic compounds are widely used as pharmaceuticals. Tacrine (THA) was the first drug approved for the treatment of Alzheimer’s disease (AD) and a great effort has been made to design and synthesize new THA-analogues in order to evaluate their beneficial effects as therapeutic agents in this disease.1-6 Contrasting with the pharmaceutical interest, mass spectrometric studies of these compounds and of some...
