a Mean values and standard deviation of the percentage of positively stained nuclei for the TUNEL assay in diaphragm (white bars) and gastrocnemius (black bars) muscles of the 20-week cohort of animals. Statistical significance is represented as follows: **p ≤ 0.01 and ***p ≤ 0.001 between any of the intervention groups (U and E–U) and control mice. b Representative examples of positively nuclei (red arrows) stained for the TUNEL assay in the diaphragm (top panel) and gastrocnemius (bottom panel) muscles of the 20-week cohort of the different study groups of mice (calibration bar 100 μm)
