Fig. 3From: Amorphous silica nanoparticles accelerated atherosclerotic lesion progression in ApoE−/− mice through endoplasmic reticulum stress-mediated CD36 up-regulation in macrophageSiNPs promoted the stiffness of carotid artery in ApoE−/− mice. a Representative B-mode ultrasound images of the LCCA (long axis) at each timepoint. b Representative B-mode ultrasound images of LCCA (short axis) at the end of experiment. The IMT (c), PWV (d), area percent spread, diameter percent spread and global radial strain (f) of the LCCA were measured at different timepoints. e indicates the method for detecting PWV. *p < 0.05 vs Control group at the same timepoint.
