*2.7. Statistical Analysis*

Data were expressed as mean ± standard error of the mean (S.E.M.). Statistical significance of di fferences existed within the experiment. Experimental groups were examined by one-way analysis of variance (ANOVA) using SPSS (version 23.0 for Windows, SPSS Inc., Chicago, IL, USA).
