Publication number: 20090110673Abstract: Provided are methods of reducing cell death, attenuating a burst of reactive oxygen species, reducing cytotoxicity, reducing intracellular oxidant stress due species in a population of cells following hypoxia by reoxygenating the cells in the presence of a reversible electron transport chain inhibitor or under hypercarbic conditions. Also provided is a method to determine the effectiveness of a reversible electron transport chain inhibitor for reducing cell death in a population of cells.Type: ApplicationFiled: May 25, 2007Publication date: April 30, 2009Applicant: THE UNIVERSITY OF CHICAGOInventors: Terry L. Vanden Hoek, Zuo-Hui Shao, Chang-Qing Li, David G. Beiser, Lance Becker

Patent number: 5882339Abstract: Apparatus for supplying liquid to a body cavity during an endoscopic procedure includes a feedback loop-controlled liquid supply device inherently capable of supplying liquid at a substantially constant pressure substantially independent of the flow rate of liquid delivered by the liquid supply device within a relatively wide range of flow rate. Also disclosed are a disposable plastic pump cassette having an inflow pump in a housing, and an operative cannula. The surgical procedure is performed with continuous control over the body cavity pressure, regardless of the outflow flow rate.Type: GrantFiled: June 7, 1995Date of Patent: March 16, 1999Assignee: Smith & Nephew, Inc.Inventors: David G. Beiser, Steven B. Woolfson, Kenneth W. Krause
