Data presented as mean (n = 3) ± SD values for the same parameter evaluated followed by different superscript lowercase letters are significantly different at p < 0.001, according to Tukey’s test. Y Level of significance: N.S.: not significant (p > 0.05); * significant at p < 0.05; ** significant at p < 0.01; *** significant at p < 0.001.
