Wound Healing Delay in the ZDSD Rat.

Animal models of diabetic delayed wound healing are essential to the development of strategies to improve clinical approaches for human patients. The Zucker diabetic Sprague Dawley (ZDSD) rat has proved to be an accurate model of diet-induced obesity and diabetes and we evaluated the utility of the ZDSD rat as a model for delayed wound healing associated with diabetes and obesity. Groups of ZDSD and Sprague Dawley (SD) rats were placed on a diabetogenic diet and evaluated two weeks later for hyperglycemia, as a sign of diabetes.

Update on late relapse of germ cell tumor: a clinical and molecular analysis.

Purpose: Analysis of patients with late relapse (LR) of germ cell tumor (GCT) with reports on clinical characteristics, outcomes, and molecular and cytogenetic features.

Patients And Methods: Eighty-three patients evaluated at Indiana University from 1993 through 2000 for relapse of GCT more than 2 years from initial therapy were reviewed. Available specimens were investigated for expression of the transcription regulator FoxD3 and apurinic/apyrimidinic endonuclease and the presence of chromosome 12 abnormalities.
