NO and ROS changes in response to homocysteine (Hcy) and TEMPOL. (A): Representative images by fluorescence microscopy of NO (red fluorescence) and ROS (green fluorescence) generation in response to Hcy and Hcy + TEMPOL treatment conditions in adipose tissue arterioles collected obese subjects (n = 10) and non-obese controls (n = 10). The charts present NO (B) and ROS (C) fluorescent signals that were measured and expressed in arbitrary units using NIH Image J software. All measures are represented as means± SE. * (p < 0.05) for comparing L-NAME to baseline in each group, and † (p < 0.05) for comparing obese subjects with controls.
