Photobiomodulation and Oxidative Stress: 980 nm Diode Laser Light Regulates Mitochondrial Activity and Reactive Oxygen Species Production

Figure 5

Effects of the 980 nm laser on oxidative stress production and lipid peroxidation: (a) superoxide production; (b) malondialdehyde (MDA) level. Each panel is representative of three independent experiments, and data are expressed as . , , and indicate a significant difference for , 0.001, and 0.001, respectively, between the nontreated sample (0 W) and the samples irradiated with different powers (0.1, 0.5, 0.8 W) for 60 seconds; spot size 0.78 cm2.
