Administration of Rotaglide™ solution for treating refractory severe radial artery spasm: A case report.

Severe radial artery spasm is a complication of transradial cardiac catheterization. We describe a case of severe radial artery spasm causing catheter entrapment. The spasm was refractory and resistant to intra-arterial vasodilators, systemic vasodilators, and moderate sedation.

Point mutations in Escherichia coli DNA pol V that confer resistance to non-cognate DNA damage also alter protein-protein interactions.

Y-family DNA polymerases are important for conferring cellular resistance to DNA damaging agents in part due to their specialized ability to copy damaged DNA. The Escherichia coli Y-family DNA polymerases are encoded by the umuDC and dinB genes. UmuC and the cleaved form of UmuD, UmuD', form UmuD'2C (pol V), which is able to bypass UV photoproducts such as cyclobutane pyrimidine dimers and 6-4 thymine-thymine dimers, whereas DinB is specialized to copy N(2)-dG adducts, such as N(2)-furfuryl-dG.
