The advantage of using SNP array in clinical testing for hematological malignancies--a comparative study of three genetic testing methods.

Cytogenetic methods, including G-banded chromosome analysis and fluorescence in situ hybridization (FISH) analysis, serve as a critical part of routine clinical testing for hematological malignancies and provide important diagnostic and prognostic information; however, the limitations of cytogenetic methods, including the requirement for actively dividing cells and lower resolution of G-banded chromosome analysis as well as the inability of both G-banded chromosome analysis and FISH to detect copy number neutral loss of heterozygosity (CN-LOH), can result in a failure to detect genomic abnormalities with diagnostic and prognostic significance. Here, we compared the abnormality detection rate of clinically requested testing (i.e.

Total parenteral nutrition attenuates cerulein-induced pancreatitis in rats.

Objectives: Our aim was to determine if total parenteral nutrition (TPN)-induced pancreatic atrophy and Hsp70 expression attenuates cerulein-induced pancreatitis in rats.

Methods: Rats were randomized to a 7-day course of saline infusion plus a semipurified diet or TPN, with or without an intravenous cerulein injection or vehicle on day 7, and killed 1 or 6 hours after the injection. Based on a pilot study, 1 hour was the primary time point.
