Transient reduction in vascular function following systemic large muscle group exercise has previously been reported in humans. The mechanisms responsible are currently unknown. We hypothesised that sympathetic nervous system activation, induced by cycle ergometer exercise, would contribute to post-exercise reductions in flow-mediated dilatation (FMD). Ten healthy male subjects (28 ± 5 years) u...

For economies in which the real rate of return on money is too low, the standard prescription is to deflate prices according to the Friedman rule. Implicit in this recommendation is the availability of a lump-sum tax instrument. In this paper, I view lump-sum tax obligations as a form of debt subject to default. While individuals may agree to honor such obligations ex ante, a lack of commitment...

In this paper, we examine deflation-based algebraic multigrid methods for solving large systems of linear equations. Aggregation the unknown terms is applied coarsening, while deflation techniques are proposed improving rate convergence. More specifically, V-cycle strategy adopted, in which, at each iteration, solution computed by initially decomposing it utilizing two complementary subspaces. ...

According to standard economic theory, deflation is the necessary consequence of optimal monetary policy. In 1969, Milton Friedman argued that, under the optimal policy, the nominal interest rate should be zero, and the price level should fall steadily at the real rate of interest. Since then, Friedman’s argument has been confirmed in a formal setting (see e.g., V. V. Chari et al., 1996; Harold...

BACKGROUND The purpose of this study was to determine whether or not prefilled breast implants retain their volume in packaging. METHODS This study examined 32 Poly Implant Prosthesis prefilled textured saline breast implants. All of these implants were within the manufacturer's expiration date at the time of weighing. No holes were visible on any of the implants. All were weighed on an elect...

Pressure controlled intermittent coronary sinus occlusion (PICSO) has been found to substantially salvage ischemic myocardium. By elevating venous pressure two mechanisms are involved namely the distention of venous vessels inducing mechanotransduction as well as a redistribution of venous flow towards ischemic areas. Mechanotransduction in endothelial cells inducing changes in the ischemic hea...
