Abordagem da glicosúria renal na criança: a propósito de um caso clínico
Pais, Patrícia; Reis, Filipa; Fraga, Sofia; Ferreira, Maria Gomes; Amaral, RosárioIntroduction: The accidental finding of glycosuria should lead to the exclusion of diabetes mellitus. In the absence of hyperglycemia, glycosuria is probably of renal origin. It can be isolated, as in familiar renal glycosuria, or it can be part of a hereditary tubular disorder such as Fanconi-Bickel syndrome or associated with an acquired tubular dysfunction. The renal and tubular function should be investigat...
Analytical methods applied to the chemical characterization and antioxidant pro...
Reis, Filipa S.; Barros, Lillian; Sousa, Maria João; Martins, Anabela; Ferreira, Isabel C.F.R.The chemical composition and the antioxidant potential of three species of wild mushrooms from Northeastern Portugal, namely Agaricus albertii, Agaricus urinascens var. excellens, and Pleurotus eryngii, were compared. Standard procedures were followed in the nutritional value evaluation, while chromatographic procedures were used to analyze free sugars, fatty acids, tocopherols, phenolic compounds, and organic ...
Chemical characterization of the medicinal mushroom Phellinus linteus (Berkeley...
Reis, Filipa S.; Barreira, João C.M.; Calhelha, Ricardo C.; Van Griensven, Leo J.I.D.; Ćirić, Ana; Glamočlija, Jasmina; Soković, MarinaMushrooms are widely appreciated for their organoleptic qualities, being also recognized as good sources of bioactive compounds that provide antioxidant, antimicrobial and cytotoxic activities. Polysaccharides (including glucans) are often pointed out as the most bioactive compounds isolated from mushrooms, but other molecules such as triterpenoids, might also be highlighted for their bioactivity. In scientific...
A methanolic extract of Ganoderma lucidum fruiting body inhibits the growth of ...
Oliveira, Marta; Reis, Filipa S.; Sousa, Diana; Tavares, Catarina; Lima, Raquel T.; Ferreira, Isabel C.F.R.; Santos, Tiago; Vasconcelos, M. HelenaGanoderma lucidum is one of the most extensively studied mushrooms as a functional food and as a chemopreventive agent due to its recognized medicinal properties. Some G. lucidum extracts have shown promising antitumor potential. In this study, the bioactive properties of various extracts of G. lucidum, from both the fruiting body and the spores, were investigated. The most potent extract identified was the met...
Cultivated strains of Agaricus bisporus and A. brasiliensis: chemical character...
Stojković, Dejan; Reis, Filipa S.; Glamočlija, Jasmina; Ćirić, Ana; Barros, Lillian; Van Griensven, Leo J.I.D.; Ferreira, Isabel C.F.R.; Soković, MarinaAgaricus bisporus (J. E. Lange) Emil J. Imbach and Agaricus brasiliensis Wasser, M. Didukh, Amazonas & Stamets are edible mushrooms. We chemically characterized these mushrooms for nutritional value, hydrophilic and lipophilic compounds. The antioxidant and antimicrobial activities of methanolic and ethanolic extracts were assessed. Hepatotoxicity was also evaluated. The ethanolic extract of both species was te...
Plano individual de intervenção: proposta para uniformização nas Unidades de In...
Reis, Filipa Isabel Pereira Rosa SilvaProblema de investigação: A RNCCI não desenvolveu uma imagem e linguagem comum para o Plano Individual de Intervenção o que poderá prejudicar a eficácia da comunicação dentro da própria Rede, nomeadamente, quando existe transferência de utentes entre os vários níveis de cuidados. Para além disso, apesar de existirem indicadores de Ganhos em Saúde na RNCCI, estes não quantificam os ganhos em funcionalidade que s...
Development of photovoltaic systems with concentration
Reis, Filipa, 1985-Tese de doutoramento, Sistemas Sustentáveis de Energia, Universidade de Lisboa, Faculdade de Ciências, 2013 ; The concept of Concentration Photovoltaic (CPV) systems appeared as an attempt to reduce the cost of Photovoltaic (PV) technology. In these systems, savings are achieved by the reduction of the area of the expensive PV cell which is compensated by the increase in the light intensity on the device throu...
Tirmania pinoyi: chemical composition, in vitro antioxidant and antibacterial a...
Stojković, Dejan; Reis, Filipa S.; Ferreira, Isabel C.F.R.; Barros, Lillian; Glamočlija, Jasmina; Ćirić, Ana; Nikolić, Miloš; Stević, TanjaDesert truffle, Tirmania pinoyi (Maire) Malençon from Libya was chemically characterized in nutritional value, primary and secondary metabolites. Antioxidant (scavenging activity, reducing power and inhibition of lipid peroxidation) and antibacterial activity of its methanolic extract alone and in combination with potassium metabisulfite (E224) were evaluated under in vitro conditions. Furthermore, the effect o...
Nutrients and non-nutrients composition and bioactivity of wild and cultivated ...
Stojković, Dejan; Reis, Filipa S.; Barros, Lillian; Glamočlija, Jasmina; Ćirić, Ana; Van Griensven, Leo J.I.D.; Soković, Marina; Ferreira, Isabel C.F.R.Mushrooms have been reported as sources of biomolecules with various potential. Coprinus comatus was studied to obtain information about this species, comparing cultivated and wild samples. Free sugars, fatty acids, tocopherols, organic acids and phenolic acids were analysed by chromatographic techniques coupled to different detectors. C. comatus methanolic extractwas tested for its antioxidant potential (reduc...
Chemical characterization and bioactivity of two different species of wild mush...
Reis, Filipa S.; Stojković, Dejan; Soković, Marina; Glamočlija, Jasmina; Ćirić, Ana; Martins, Anabela; Ferreira, Isabel C.F.R.Mushrooms are widely appreciated all over the world for their nutritional properties, and also for their pharmacological value. They have been considered valuable health foods, being a source of many different bioactive compounds such as unsaturated fatty acids, tocopherols, organic acids and phenolic compounds. The present work reports and compares the nutritional value, bioactive compounds and antioxidant pro...
