Figure 7From: 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 three physicochemically different TiO 2 particles and compared to control cells. The NO production was measured in absence or presence of the NO synthase inhibitor diphenyleneiodonium chloride (DPI). Values are means ± SEM. * P < 0.05 control versus nTiO2. # P < 0.05 significant treatment effect within group.Back to article page
