All experiments were conducted in triplicates
(n=3) and an analysis of variance (ANOVA) was
performed. Statistical analyses were performed using
IBM SPSS software (IBM SPSS Statistics 19). Data
were statistically analyzed using one-way ANOVA
and Tukey tests. The data were expressed as mean ±
standard deviations. The confidence interval at 95%
(p < 0.05) was used for statistical significance.
