Vascular reactivity of coronary resistance arterioles at 12 months. (A) Endothelium-dependent dilation of coronary arterioles from Sham-Control and nano-TiO2-exposed animals at 12 months was determined using pressure myography. ACh, Acetylcholine. (B) Endothelium-independent dilation of coronary arterioles from Sham-Control and nano-TiO2-exposed animals at 12 months was determined using pressure myography. SNP, Sodium nitroprusside. Values are shown as mean ± SEM. n = 4–5. Statistics were analysed with two-way ANOVA., *Indicates p ≤ 0.05 versus Sham-Control (AIR) group.
