A comprehensive assessment of the transcriptome of cork oak (Quercus suber) thr...

Background: Cork oak (Quercus suber) is one of the rare trees with the ability to produce cork, a material widely used to make wine bottle stoppers, flooring and insulation materials, among many other uses. The molecular mechanisms of cork formation are still poorly understood, in great part due to the difficulty in studying a species with a long life-cycle and for which there is scarce molecular/genomic inform...

Caracterização biofísica e ecológica dos povoamentos de medronheiro amostrados ...

O medronheiro (Arbutus unedo L.) é uma espécie autóctone, com distribuição ubíqua em Portugal, tolerante ao stress hídrico, a solos de baixa fertilidade e com uma resistência ativa a incêndios florestais. O fruto é utilizado na produção de aguardente, a principal fonte de rendimento, e o seu consumo em fresco (medronho), com potencial antioxidante, representa uma nova oportunidade. Verifica-se, atualmente, um f...

Polypharmacy in the elderly: therapy adherence

The elderly population has been growing significantly, leading to an increased prevalence of chronic diseases and consequent taking medication. Polypharmacy is the chronic and simultaneous use of different drugs by the same individual, and the elderly are the more susceptible. The complex therapies of elderly can lead to therapy non-adherence, increasing several health risks. This study aimed to estimate the p...

Tourists’ perceptions of world heritage destinations: The case of Guimarães (Po...

Guimara˜es is a UNESCO world heritage site, deemed as such in 2001 and hosted the 2012 European Capital of Culture. This paper examines the profile, destination image, and motivations of tourists’ visiting behaviors in Guimara˜es before the cultural event. Based on survey responses from 276 tourists, we found that tourists arriving in Guimara˜es had previously visited the two most important cities in the northe...

Selective methoxylation of limonene over ion-exchanged and acid-activated clays

In this study, we report the use of clay-based catalysts in the methoxylation of limonene, for the selective synthesis of terpinyl methyl ether. Na-SAz-1, Ca-SWy-2 and Sap-Ca source clays and a montmorillonite (SD) from Porto Santo, Madeira Archipelago, Portugal were modified by (i) ion-exchange with Al, Fe, Ni and Na and (ii) acid activation, to produce catalysts with markedly different acidic and textural pr...

Effect of filler content on morphology and physical-chemical characteristics of...

Poly(vinylidene fluoride) electrospun membranes have been prepared with different NaY zeolite contents up to 32%wt. Inclusion of zeolites induces an increase of average fiber size from ~200 nm in the pure polymer up to ~500 nm in the composite with 16%wt zeolite content. For higher filler contents, a wider distribution of fibers occurs leading to a broader size distributions between the previous fiber size valu...

Bioactive albumin functionalized polylactic acid membranes for improved biocomp...

Biocompatibility is a major challenge for successful application of many biomaterials. In this study the ability to coat chemically and enzymatically activated poly(L-lactic acid) (PLA) membranes with heat denatured human serum albumin to improve biocompatibility was investigated. PLA membranes hydrolyzed with NaOH or cutinase and then treated with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, hydrochloride (E...

Síndrome do bebé abanado – experiência de 10 anos de um Serviço de Cuidados Int...

Introdução: O Síndrome do Bebé Abanado é uma das causas de lesão não acidental mais difíceis de diagnosticar. Objetivos: Caracterizar os doentes internados no Serviço de Cuidados Intensivos Pediátricos (SCIP) com Síndrome do Bebé Abanado. Material e Métodos: Estudo retrospetivo dos doentes internados no SCIP do Centro Hospitalar de São João com o diagnóstico de Síndrome de Bebé Abanado de 1 de Janeiro de 1999 a...
