Anemia and immunological dysfunction (i.e. immunosenescence) are commonly found in older subjects and nutritional approaches are sought to counteract these phenomena. Spirulina is a filamentous and multicellular bule-green alga capable of reducing inflammation and also manifesting antioxidant effects. We hypothesized that Spirulina may ameliorate anemia and(More)
RATIONALE AND OBJECTIVES To evaluate the effect of Magnetic Resonance Imaging (MRI) performed at 1.5-Tesla on current generation pacemakers and ICDs to identify safe parameters for MRI examinations. METHODS Pacemakers (Identity ADx XL DR+ 5386 and Identity ADx DR + 5380 generators; 1688T/52-cm atrial and ventricular leads) and ICDs (Atlas + V-243, Epic +(More)
Recent evidence for separate forms of attention for different visual attributes seems to conflict with Duncan's "integrated competition" theory of visual attention. To resolve this conflict, we established attention-operating characteristics for four pairs of visual discriminations. While one task was common to every pair, the other tasks were different and(More)
In recent years, robotic assistance for surgical procedures has grown on a worldwide scale, particularly for use in more complex operations. Such operations usually require meticulous handling of tissue, involve a narrow working space and limit the surgeon's sense of orientation in the human body. Improvement in both tissue handling and working within a(More)
The aim of this study was to assess the use of dental services and age at first dental visit in preschool children in Canela, Rio Grande do Sul State, Brazil. A representative sample of under-five children was surveyed on National Children's Vaccination Day. Children's parents completed questionnaires containing socio-demographic data and age at first(More)

The project presents a memory arbiter system capable of allowing two systems to communicate to the same DDR3 SDRAM memory. The arbiter was designed using Verilog, implemented using Xilinx Integrated Software Environment (ISE) and validated using iSim and ChipScope. The final design is implemented on a Virtex 6 FPGA chip. The arbiter can achieve a maximum(More)
