Ultrasound characterization of middle ear effusion.

Purpose: To further enhance and assess the ability to characterize middle ear effusion (MEE) using non-invasive ultrasound technology.

Materials And Methods: This is a prospective unblinded comparison study. Fifty-six children between the ages of 6 months and 17 years scheduled to undergo bilateral myringotomy with pressure equalization tube placement were enrolled.

In vivo evaluation of a new surfactant polymer coating mimicking the glycocalyx of endothelial cells.

The purpose of this study was to demonstrate that a proprietary surfactant polymer (SP) coating does not adversely affect the hemodynamic performance of cardiopulmonary bypass (CPB) or gas exchange in oxygenators. The new coating was applied to a CPB circuit including cannulae, reservoir, oxygenator, and blood pump implanted into 12 pigs, divided into groups with either coated or noncoated pumps. CPB flow was maintained at a fixed level of approximately 2.
