Viability assay and DNA double strand break induction in nervous system cells e...
Fernandez-Bertolez, N.; Touzani, A.; Martinez, L.; Méndez, J.; Ramos-Paz, L.; Reis, A.T.; Fraga, S.; Costa, C.; Teixeira, J.P.; Pásaro, E.Cerium dioxide nanoparticles (CeO2 NP) show antioxidant enzyme mimetic properties and free radical scavenging activity. These properties make them a promising material for biomedical applications, but their potential adverse effects are not totally understood yet. Our objective was to assess the biological behaviour of CeO2 NP in human neuronal and glial cells. After carrying out the physical-chemical character...
Utility of salivary leucocytes for biomonitoring of human exposure to nanomater...
Valdiglesias, Vanessa; Fernández-Bertólez, Natália; Touzani, A.; Mendéz, J.; Martinez, L.; Pásaro, E.; Reis, A.T.; Fraga, S.; Teixeira, J.P.; Costa, C.Metal-based nanoparticles (NP) are being increasingly used in a wide variety of applications in consumer products and biomedical practices. As a result, human exposure to these nanomaterials is frequent, becoming a concern to public health. Human salivary leucocytes have been proposed as a proper biological sample for the comet assay, becoming an adequate non-invasive alternative model to evaluate DNA damage. I...
