*2.7. Calculations and Statistical Analysis*

All experiments were performed three times per assay. The data for all experiments were given as the arithmetic mean percentage ± standard deviation in relation to control. Statistical analysis was performed using analysis of variance (ANOVA) followed by Dunnett's multiple comparison tests. Differences were considered significant in respect to the control group at *p* < 0.05 (\*), *p* < 0.01 (\*\*) and at *p* < 0.001 (\*\*\*).
