[Data validity in a French diagnosis-related group information program].

Background: Long-term intratracheal ventilated patients need continuous artificial ventilation support. After the acute periods, these patients may benefit from dedicated follow-up in rehabilitation care centers. In this paper, we aimed to study the validity of the data provided by a French diagnosis-related group (DRG) information system.

Efficient analysis of egg yolk proteins and their thermal sensitivity using sodium dodecyl sulfate polyacrylamide gel electrophoresis under reducing and nonreducing conditions.

The multiple functional properties of egg yolk are mostly influenced by its complex protein composition. The high lipid content of egg yolk as well as the low solubility of delipidated egg yolk lipoproteins make analysis by conventional chromatographic or electrophoretic techniques a difficult task. This work describes a method to profile egg yolk proteins after delipidation with acetone using sodium dodecyl sulfate polyacrylamide gel electrophoresis on precast 8-18% T polyacrylamide gradient gels.
