Mobility-Aware Privacy-Preserving Mobile Crowdsourcing.

The increasing popularity of smartphones and location-based service (LBS) has brought us a new experience of mobile crowdsourcing marked by the characteristics of network-interconnection and information-sharing. However, these mobile crowdsourcing applications suffer from various inferential attacks based on mobile behavioral factors, such as location semantic, spatiotemporal correlation, etc. Unfortunately, most of the existing techniques protect the participant's location-privacy according to actual trajectories.

AngII-induced glomerular mesangial cell proliferation inhibited by losartan via changes in intracellular calcium ion concentration.

This study investigated the changes in intracellular [Ca(2+)](i) (intracellular calcium ion concentration) and TRPC6 (transient receptor potential channel 6) expression during angiotensin II (AngII)-induced glomerular mesangial cell (GMC) proliferation, as well as the inhibitory effect of losartan. GMC cultures were split into four groups treated for 24 h: Group N (blank control group), Group A (10(-7 )mol/L AngII), Group LT (10(-7 )mol/L AngII and 10(-5 )mol/L losartan), and Group Pred (10(-7 )mol/L AngII and 10(-5 )mol/L prednisone). GMCs proliferation was measured by the MTT and trypan blue assays.
