Fig. 7. Expression of caspase 3 in diaphragms of the mechanical ventilation (MV), continuous positive airway pressure (CPAP), and control (CTRL) groups. Representative immunoblots (A ) and group mean quantification of protein concentrations measured in diaphragm tissues obtained from the MV, CPAP, and CTRL groups for caspase 3 (B ). *P < 0.05 between MV and CPAP groups. Values are median and twenty-fifth to seventy-fifth quartiles. NS = not significant.
