Fig. 16From: Respiratory and systemic impacts following MWCNT inhalation in B6C3F1/N miceChanges for total cathepsins in the blood plasma of mice following 30-day MWCNT exposure + 10 days recovery. Mean ± SEM relative fluorescence units representing total cathepsin levels in the blood plasma following MWCNT exposure or sham. Asterisks *** indicate significance at P < 0.001 compared to the air control and 0.06 mg/m3 exposure groups. All data expressed as mean ± SEM (n = 8)Back to article page
