Advanced Healthcare Materials, EarlyView.This study develops a 3D vascular injury model using a microphysiological system that mimics key features of intimal hyperplasia. Antiproliferative drugs reduced VSMC proliferation but worsened endothelialdenudation. A combination of diphenyleneiodonium and quercetin effectively reduced proliferation and migration of VSMC and inflammation while ...

The occupancy of two distinct conformations by active-site histidine-119 in crystals of ribonuclease is modulated by pH [PDF]
, 1994 Structures of a semisynthetic RNase have been obtained to a resolution of 2.0 Å at pH values of 5.2, 6.5, 7.5, and 8.8, respectively. The principle structural transformation occurring over this pH range is the conversion of the side chain of active site ...
