Understanding the environmental responses of an invasive species is critical in predicting how ecosystem composition may be transformed in the future, especially under climate change. In this study, Crassostrea gigas, a species well adapted to the highly variable intertidal environment, was exposed to the chronic environmental challenges of temperature (19(More)
Bismuth preparations are used world-wide for the management of peptic ulcer disease, for eradication of Helicobacter pylori, and in the prevention and treatment of diarrhoea. However neurological toxicity of bismuth has always been a major concern and evidence has been found of the absorption of bismuth. Recent studies have suggested that the absorption of(More)
The neurotoxicity of organic solvents has long been recognized. Some are used as anesthetic agents, others in various industries. Their acute effect has been well documented since the nineteenth century, but more recently they have become notorious as the cause of addiction to glue sniffing. They may alter the immune system by causing lymphopenia, impairing(More)
Bone mass distribution and structure are dependent on mechanical stress and adaptive response at cellular and tissue levels. Mechanical stimulation of bone induces new bone formation in vivo and increases the metabolic activity and gene expression of osteoblasts in culture. A wide variety of devices have been tested for mechanical stimulation of cells and(More)
Fibrodysplasia Ossificans Progressiva (FOP) is a rare hereditary connective tissue disease, genetically inherited as an autosomal dominant trait with complete penetrance but variable expressivity. Onset is typically in childhood and progressive involvement of the spine and proximal extremities leads to immobility and articular dysfunction. We present two(More)
Autochthonous hepatitis E virus (HEV) infection has been increasingly reported in Europe and the United States, mostly arising from genotype 3 and less frequently genotype 4. We report here on a patient with HEV genotype 3a infection complicated by Guillain-Barré syndrome in Portugal in December 2012. We draw attention to the diagnosis of autochthonous HEV(More)
Endoluminal reconstruction with flow diverter devices represents an innovative technique in the treatment of intracranial aneurysms.These new stents, self-expandable and of low porosity, are released through the microcatherization of the parent artery. The main goal of these systems is thereby rebuilding the vessel wall and excluding the aneurysmal(More)
Eleven cases of legionnaires disease, all patients living in the same municipality, were admitted to a district hospital in northern Portugal. Preliminary investigations suggested an association with the events of the annual festivities in that municipality. Legionella pneumophila was not isolated from any of the suspected sources, but evidence from a case(More)
