PVT1 lincRNA signals an androgen-dependent transcriptional activation program of oncogenes in prostate cancer cells. [PDF]
Int J CancerWhat's New? Unraveling the networks that regulate androgen receptor (AR) function is critical to better understanding prostate cancer development and progression. Of particular interest in this regard is the long non‐coding RNA PVT1, which regulates gene expression in cancer and is upregulated in prostate tumors.

Safety and Efficiency Analysis of Turbo Roundabout with Simulations Based on the Lujiazui Roundabout in Shanghai [PDF]
Sustainability, 2020 Traditional multilane roundabouts have many branch lanes without traffic signs and channelization, which leads to a high tendency for traffic collisions. Turbo roundabouts are a new design that has the potential to reduce lane-change conflicts using canalization to force drivers to keep in specific lanes based on their intended destination.

Moving from Conventional Roundabouts to Turbo-roundabouts
Procedia, Social and Behavioral Sciences, 2014 AbstractThis paper introduces the turbo-roundabout concept and compares its performance with the conventional double-lane roundabout in terms of safety and capacity. While researchers agree as to the safety benefits of turbo-roundabouts, improvement in terms of capacity is still open to discussion. The application of a new calculation method shows that

Conversion of a Semi-two Lanes Roundabout into a Turbo-roundabout: A Performance Comparison
Procedia Computer Science, 2016 AbstractIn the last years, as regards the functional design of at-grade intersections, near to classic layouts (signal-controlled junctions, roundabouts, etc.) a new solution has born: the “turbo-roundabout”. It is a canalized multilane oval intersection with a non-traversable or partially traversable center island and with a spiral circulatory ...
