Anchoring of Fe-MIL-101-NH to the Polymer Membrane Matrix through the Hinsberg Reaction to Promote Conductivity of SPEEK Membranes.

SCPEEK@MOF proton exchange membranes, where SCPEEK is sulfinyl chloride polyether ether ketone and MOF is a metal-organic framework, were prepared by doping Fe-MIL-101-NH into polymers. The amino group in the MOF and the -SOCl group in thionyl chloride polyether ether ketone cross-link to form a covalent bond through the Hinsberg reaction, and the prepared composite membrane has stronger stability than other electrostatic interactions and simple physical doping composite membranes. The formation of covalent bonds improves the water absorption of the composite membrane, which makes it easy for water molecules to form hydrogen bonds.

[Increasing cardiopulmonary bypass flow volume improves outcome of patient with carotid stenosis undergoing coronary artery bypass grafting].

Objective: To evaluate the effect of increasing cardiopulmonary bypass (CPB) flow volume in improving outcome of patients with carotid artery stenosis performed coronary artery bypass grafting (CABG) procedure.

Methods: Fifty-one patients data collected from January 2006 to March 2008 and divided into two groups (A and B) based on the degree of the carotid artery stenosis diagnosed by ultrasound. Group A included 15 cases with one or both carotid artery stenosis more than 50%, 14 male and 1 female, aged (68.
