Fig. 5From: Ultrasmall superparamagnetic iron oxide nanoparticles acutely promote thrombosis and cardiac oxidative stress and DNA damage in miceProthrombin time (PT, a) and activated partial thromboplastin time (aPTT, b) measured 1 h after the intravenous administration of ultrasmall superparamagnetic iron oxide nanoparticles (USPIO), diesel exhaust particles (DEP) or saline (control) in mice. *P < 0.01 and **P < 0.001 compared with the corresponding saline-treated group. Data are mean ± SEM (n = 4–6)Back to article page
