*2.7. Data Analysis*

All tests were performed in triplicate, and the values were expressed as mean ± standard deviation (SD). SPSS 22 (International Business Machines Corp, Armonk, NY, USA) and Excel 2007 (Microsoft Corporation, Redmond, WA, USA) were applied for data analysis. One-way ANOVA and post hoc Tukey test were performed to compare means of more than two samples, and *p* value less than 0.05 was defined as statistical significance.
