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...
Sickness presenteeism in the aftermath of COVID-19: Is presenteeism remote-work...
Ferreira, A. I.; Mach, M.; Martinez, L.; Miraglia, M.Due to the confinement imposed by the COVID-19 pandemic situation, companies adopted remote work more than ever. The rapid rise of remote work also affected local life and many employers introduced or extended their telework activities because of the associated advantages. However, despite the evident positive benefits, some employees were pressured to work remotely while ill. This evidence brought new challeng...
“To work, or not to work, that is the question” – Recent trends and avenues for...
Ruhle, S. A.; Breitsohl, H.; Aboagye, E.; Baba, V.; Biron, C.; Correia Leal, C.; Dietz, C.; Ferreira, A. I.; Gerich, J.; Johns, G.; Karanika-Murray, M.This position paper brings together recent and emerging developments in the field of presenteeism. A critical synthesis of the evidence is needed due to persisting conceptual and methodological challenges as well as the increased volume of research in the field. This paper integrates emerging evidence and critical thinking into three areas: (1) concept, (2) measurement and methodological issues, and (3) the con...
Working sick and out of sorts: a cross-cultural approach on presenteeism climat...
Ferreira, A. I.; Mach, M.; Martinez, L.; Brewster, C.; Dagher, G.; Perez-Nebra, A.; Lisovskaya, A.A climate of presenteeism has important effects on employee well-being and the organization itself. Our study, based on surveys of health sector employees in six different countries (Brazil, Ecuador, Lebanon, Portugal, Russia and Spain) examines whether organizational justice plays a mediating role in the relationship between a presenteeism climate in the organization and work–family conflict (WFC). Our results...
Supervisor support, role ambiguity and productivity associated with presenteeis...
Zhou, Q.; Martinez, L.; Ferreira, A.; Rodrigues, P.Integrating the social informational processing perspective and conservation of resources theory, we proposed and examined the impact of supervisor support and role ambiguity on productivity associated with presenteeism and the mediating effect of role ambiguity on the link between supervisor support and productivity associated with presenteeism. The results based on the longitudinal data from 99 employees from...
