BACKGROUND Upper limb (UL) impairment is the most common disabling deficit following a stroke. Previous studies have suggested that transcranial direct current stimulation (tDCS) enhances the effect of conventional therapies. OBJECTIVE This pilot double-blind randomized control trial aimed to determine whether or not tDCS, combined with Wii virtual(More)
Environmental conditions favor the predominance of dense populations of cyanobacteria in reservoirs in northeastern Brazil. The aim of this study was to understand cyanobacterial population dynamics in the rainy and dry seasons at two depths in the Arcoverde reservoir. Microalgae and cyanobacteria samples were collected during 24 hours with intervals of 4(More)
The rat double-SAH model is one of the standard models to simulate delayed cerebral vasospasm (CVS) in humans. However, the proof of delayed ischemic brain damage is missing so far. Our objective was, therefore, to determine histological changes in correlation with the development of symptomatic and perfusion weighted imaging (PWI) proven CVS in this animal(More)
Previous studies have documented structural and functional changes induced by ethanol-erythrocyte membrane interaction. In order to perform an in vitro study on the effect of different ethanol concentrations on erythrocyte hemorheologic properties, blood samples were collected from 21 male donors at the Hospital of Santa Maria. Whole blood aliquots were(More)
Delayed ischemic brain tissue damage in the time course of cerebral vasospasm in the rat double-subarachnoid hemorrhage (SAH) model has been described before. However, in order to enhance hemodynamic insufficiency during cerebral vasospasm (CVS), we performed—in a modification to the standard double-hemorrhage model—an additional unilateral common carotid(More)
