*2.7. Statistical Analysis*

All samples were analyzed in triplicate (*n* = 3) and the outcomes were reported as the mean ± standard deviation (SD). The data were statistically analyzed by Student's t-test using Microsoft Office Excel computer software and by one-way analysis of variance (ANOVA) with post hoc Dunnett's test using SigmaPlot 11.0 computer software. The difference showing a p level of 0.05 or lower was considered statistically significant.
