Impact of health care reform on academic medical centers.

The impact of health care reform on academic medical centers will be just as great as it is on community practices. The economics of academic medical centers and training programs has been challenging, and will become even more so as funding is cut and the demand for regional integrated systems mounts. This article is one of the first to articulate these challenges and is written by authors well positioned to understand this arena.

Hurricane Katrina's impact on Tulane's teaching hospitals.

On Monday, August 29, 2005 Hurricane Katrina passed east of New Orleans causing minimal damage to Tulane's Medical Center. Later that day, levees that protected the city failed and several feet of water entered the hospitals and school buildings. Emergency generators provided power for 36 hours before running out of fuel.

Surviving Hurricane Katrina: reconstructing the educational enterprise of Tulane University School of Medicine.

Hurricane Katrina was one of the greatest natural disasters to ever strike the United States. Tulane University School of Medicine, located in downtown New Orleans, and its three major teaching hospitals were flooded in the aftermath of the storm and forced to close. Faculty, students, residents, and staff evacuated to locations throughout the country.

Release of peptide YY by fat in the proximal but not distal gut depends on an atropine-sensitive cholinergic pathway.

Peptide YY (PYY) is released when PYY cells in short term culture are exposed to fat suggesting that this peptide may be released by fat in the distal gut without neural stimulation. PYY is also released by fat in the proximal 1/2 of small intestine. To test the hypothesis that the release of PYY by fat in the proximal but not distal intestine may depend on an atropine-sensitive, cholinergic pathway, PYY levels were compared in four dogs equipped with duodenal and mid-intestinal fistulas when 60 mM oleate was perfused into either the proximal (between fistulas) or distal (beyond mid-intestinal fistula) 1/2 of gut at 2 ml/min for 120 min with intravenous administration of saline or atropine.
