Enhanced fatigue crack propagation performance in a high Mg-containing Al–Mg–Zn–Si alloy via two-step aging: Role of precipitation characteristics in the matrix and grain boundary

Journal of Materials Research and Technology
Fatigue crack propagation (FCP) performance of a high Mg-containing Al–Mg–Zn–Si alloy is critical for further application. Here we detailedly investigate FCP behavior and fracture morphology of the alloy under selected single and double stage aging ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

FEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.
