Fig. 1From: Subchronic exposure to titanium dioxide nanoparticles modifies cardiac structure and performance in spontaneously hypertensive ratsStudy population and experimental protocol. Flowchart describing the number of animals subjected to the different experimental procedures before and after intra-tracheal instillation of saline solution (CTRL group) or saline solution added with TiO2, at a final concentration of 2 mg/kg (TiO2-NP group). * timepoints for oxidative stress and inflammation; § timepoints for real-time PCR analysis; # timepoints for PIXE.
