Two commonly used disinfectants, a quaternary ammonium salt and povidone-iodine, were tested for effectiveness against unembryonated Ascaris suum eggs. The quaternary ammonium salt (alkyl dimethyl benzyl ammonium chloride) had no effect on the Ascaris eggs (10 minutes and 22°C) when compared with the controls in water with egg viabilities of 88.8% ± 3.3%(More)
BACKGROUND The aim of this study was to investigate the impact of varying hemodynamic conditions on fractional flow reserve (ratio of pressure distal [Pd] and proximal [Pa] to stenosis under hyperemia) in an in vitro setting. Failure to achieve maximal hyperemia and the choice of hyperemic agents may have differential effects on coronary hemodynamics and,(More)
