Respiratory dialysis with an active-mixing extracorporeal carbon dioxide removal system in a chronic sheep study.

Purpose: The objective of this study was to demonstrate the safety and performance of a unique extracorporeal carbon dioxide removal system (Hemolung, ALung Technologies, Pittsburgh, PA) which incorporates active mixing to improve gas exchange efficiency, reduce exposure of blood to the circuit, and provide partial respiratory support at dialysis-like settings.

Methods: An animal study was conducted using eight domestic crossbred sheep, 6-18 months of age and 49-115 kg in weight. The sheep were sedated and intubated, and a 15.

Permanent, nonleaching antibacterial surfaces. 1. Synthesis by atom transfer radical polymerization.

We have grown an antimicrobial polymer directly on the surfaces of glass and paper using atom transfer radical polymerization (ATRP). The method described here results in potentially permanent nonleaching antibacterial surfaces without the need to chemically graft the antimicrobial material to the substratum. The tertiary amine 2-(dimethylamino)ethyl methacrylate was polymerized directly onto Whatman #1 filter paper or glass slides via atom transfer radical polymerization.
