It has recently come to our attention that our paper Effect of high-fat diet on rat myometrium during pregnancy-isolated myometrial mitochondria are not affected published in July 2015 in Pflügers Archiv - European Journal of Physiology volume 467 issue 7 page 1539–49 contains an error due to miscalculations from our side. It concerns Table 3 Biochemical analyses of the myometrium. The last line in the table with CS activity (units CS /mg protein) should instead be CH 0.64 ± 0.08, HC 0.67 ± 0.21 and HF 0.68 ± 0.11 (mean ± SEM). The weighted one-way ANOVA with a Tukey’s post hoc test still yields non-significant results, thus the error does not alter any conclusions in the paper. The corrected table should read.
