Figure 8From: Modest effect on plaque progression and vasodilatory function in atherosclerosis-prone mice exposed to nanosized TiO2 Nitric oxide (NO) production in human umbilical vein endothelial cells (HUVECs) exposed to the NO donor SIN-1 for a total of three hours in the absence or presence of 1 mM tempol. Values are means ± SEM. * P < 0.05 SIN-1 versus unexposed cells. # P < 0.05 for difference between SIN-1 generated NO in the absence or presence of tempol.Back to article page
