  • Acquiring sub-efficient and efficient variants of novel means by integrating information from multiple social models in preschoolers 

    Altınok, Nazlı; Hernik, Mikołaj; Király, Ildikó; Gergely, György (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-08)
    Sub-efficient action routines often represent culture-specific conventional forms of actions that belong to the repertoire of cultural knowledge shared by a social group. Children readily acquire such sub-efficient routines from social demonstrations and often preserve them in their action repertoire despite encountering more efficient alternatives. This suggests that they can treat sub-efficient ...

Additional precautions required in the management of children address their increased radiosensitivity, need for accompanying ...
  • BK polyomavirus evades innate immune sensing by disrupting the mitochondrial network and promotes mitophagy 

    Manzetti, Julia; Weissbach, Fabian H.; Graf, Fabrice E.; Unterstab, Gunhild; Wernli, Marion; Hopfer, Helmut; Drachenberg, Cinthia B.; Rinaldo, Christine Hanssen; Hirsch, Hans H. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-10)
    Immune escape contributes to viral persistence, yet little is known about human polyomaviruses. BK-polyomavirus (BKPyV) asymptomatically infects 90% of humans but causes premature allograft failure in kidney transplant patients. Despite virus-specific T cells and neutralizing antibodies, BKPyV persists in kidneys and evades immune control as evidenced by urinary shedding in immunocompetent individuals. ...
