      [Abstract] The challenge-comet assay is a simple but effective approach that provides a quantitative and functional determination of DNA repair ability, and allows to monitor the kinetics of repair process. Peripheral blood ...
    • Suitability of the In Vitro Cytokinesis-Block Micronucleus Test for Genotoxicity Assessment of TiO2 Nanoparticles on SH-SY5Y Cells 

      Fernández-Bertólez, Natalia; Brandão, Fátima; Costa, C.; Pásaro, Eduardo; Teixeira, João; Laffon, Blanca; Valdiglesias, Vanessa (2021)
      [Abstract] Standard toxicity tests might not be fully adequate for evaluating nanomaterials since their unique features are also responsible for unexpected interactions. The in vitro cytokinesis-block micronucleus (CBMN) ...
    • The Centennial Collection of VDR Ligands: Metabolites, Analogs, Hybrids and Non-Secosteroidal Ligands [Review] 

      Maestro, Miguel; Seoane, Samuel (MDPI, 2022-11-21)
      [Abstract] Since the discovery of vitamin D a century ago, a great number of metabolites, analogs, hybrids and nonsteroidal VDR ligands have been developed. An enormous effort has been made to synthesize compounds which ...
