Stabilization of Cr(III) wastes by C3S and C3S hydrated matrix : comparison of two incorporation methods [PDF]

, 2015
In the present study, the influence of Cr(III) on the properties of C3S and its stabilization in C3S hydrates was investigated by either direct incorporation as Cr2O3 during C3S preparation or introduced as nitrate salt during hydration.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
