Aged rats show increased ROS production and oxidative stress at 30 dpi. a Oxyblot analysis reveals a significant increase in protein oxidation in 12-month-aged rats compared to 3-month-aged rats at 30 dpi. b Western blot analysis reveals a significant increase in 3-NT, a marker of nitrosylated proteins which is a product of oxidative stress, in 12-month-aged rats compared to that in 3-month-aged rats 30 dpi. N = 4/group. *p < 0.05, **p < 0.005. Bars represent mean ± SEM
