a Cell viability as measured by MTT assays of human nasal fibroblasts treated with various concentrations of UPM for 24 h. b Cell viability as measured by MTT assays of nasal fibroblasts treated with various concentrations of curcumin for 24 h. c Cell viability as measured by MTT assays of nasal fibroblasts treated with various concentrations of curcumin and 25 μg/mL of UPM for 24 h. Each value in the graph represents the mean ± SEM of three independent experiments. *p < 0.05, **p < 0.01, and ***p < 0.001 vs. 0 μg/mL of UPM or 0 μM of curcumin; #p < 0.05 vs. 25 μg/mL of UPM. MTT: 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide; UPM: urban particulate matter; SEM: standard error of the mean
