Disseminação de Enterobacteriaceae produtoras de beta-lactamases de espectro al...

As Enterobacteriaceae produtoras de beta-lactamases de espectro alargado (extended-spectrum beta-lactamase producing Enterobacteriaceae - EESBL) têm sido consideradas importantes agentes patogénicos hospitalares. Nos últimos tempos, a sua disseminação na comunidade, é uma realidade que pode condicionar a terapêutica empírica. A colonização fecal de pessoas saudáveis com EESBL é uma realidade que pode compromete...

Phenotypic characterization and familial risk in hyperplastic polyposis syndrome

Background. Hyperplastic polyposis syndrome (HPS) is a rare condition characterized by numerous hyperplastic polyps (HP) with a pancolonic distribution. Genetic and environmental factors, including smoking, may be responsible for phenotypic differences. Objective. To characterize HPS patients' phenotype and to determine HPS risk and colorectal cancer (CRC) risk in the first-degree relatives (FDRs). Patients and...

Sustainable management of olive rainfed orchards by the introduction of legumin...

The olive sector has a crucial economic, social, cultural and ecological relevance in the Mediterranean region, where tillage and herbicides application are still generalized practices. However, these practices oppose the recommendations of UE Common Agricultural Policy and thus, management methods that decrease requirement for agricultural chemicals are needed to reduce adverse environmental impacts. Moreover,...

A mathematical model of calcium and phosphorus metabolism in two forms of hyper...

Parathyroid hormone (PTH) plays a critical role in calcium and phosphorus metabolism. Interestingly, in two forms of hyperparathyroidism (excessive amount of PTH in the serum), the metabolic disturbances in patients with chronic kidney disease (CKD) significantly differ from those with primary hyperparathyroidism (PHP). Since an intuitive understanding of these PTH-linked regulatory mechanisms are hardly possib...

Hímen imperfurado como causa de retenção urinária: a importância do exame físico

Introdução: O hímen imperfurado (HI) é a alteração obstrutiva mais frequente do aparelho genital feminino. Estima-se que atinja 1:1000 – 1:10000 meninas. Caso clínico: Descreve-se o caso de uma adolescente de 13 anos, com história de obstipação e escoliose lombar. Recorreu ao Serviço de Urgência (SU) por episódio de retenção urinária, acompanhada de globo vesical. Apresentava uma história de dor hipogástrica co...

Cover crops for the sustainability of rainfed olive orchards

Olive tree (Olea europaea L.) is present in large areas of mainland PortugaL predominantly in less-favored regions. In spite of the fact that irrigated areas are currently increasing, most of the olive orchards are still cultivated under rainfed conditions. The success of olive farming under rainfed conditions is mainly due to the high capacity of olive tree to develop anatomical, physiological and biochemical ...

Biomarkers of oxidative stress in olive rainfed orchards under different cover ...

In Northeast Por1ugal, as in •other regions of the Mediterranean Basin, most of the olive orchards are cultivated in hilly areas under rainfed conditions and this picture will not significantly change in the near future due to natural Iimitation on water resources. We propose cover crops to Iimit soil erosion, improve soil quality and fertility, reduce the use of herbicides and other chemicals and develop the n...

Uso de resíduo da produção de alumina eletrofundida na produção de blocos e tel...

A indústria de produção de alumina eletrofundida gera atualmente um resíduo durante o seu processamento, entretanto, a inclusão do resíduo em um ciclo produtivo representa uma alternativa de reciclagem importante tanto econômica como ambientalmente. Assim, esse trabalho tem por objetivo a caracterização do resíduo da produção de alumina eletrofundida e a avaliação de sua aplicabilidade como matéria-prima cerâmi...
