Does apocynin prevent vascular effects caused by chronic exposure to low concentrations of mercury?
Mercury increases the vasoconstrictor response to phenylephrine by reducing NO bioavailability and increasing the involvement of ROS and constrictor prostanoids. Apocynin protects the vessel from the deleterious effects caused by NADPH oxidase, but not from those caused by prostanoids, thus demonstrating a two-way action.
Investor-owned nursing homes provide worse care and less nursing care than do not-for-profit or public homes.
