In Physiological Testosterone Retards Cardiomyocyte Aging in Tfm MiceviaAndrogen Receptor-independent Pathway(Vol.26,Issue 2,88-94),Figure 1 on page 91 should have been as follows:

Figure 1.Pharmacokinetic curves of testosterone concentrations after single and double 72-hour cycles of testosterone propionate injection in testicular feminized (Tfm) mice.The testosterone levels in Tfm mice receiving a single 3 mg/kg intramuscular injection of 25 mg/mL testosterone were measured at 0,0.5,1,2,4,8,16,24,32,48,and 72 hours after injection (n=3 at each time point,the solid line).An additional 3 mg/kg intramuscular injection of 25 mg/mL testosterone was administered 72 hours after the first injection,and the testosterone levels were measured at 1,2,4,8,24,and 72 hours after the second injection (n=3 at each time point,the dashed line).The area between the parallel dotted lines indicates the physiological range of testosterone concentration measured with male littermates (11.3-30.2 nmol/L,n=9).
