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.

Diagnostic Yield of Microscopic Colitis in Open Access Endoscopy Center.

Background: The diagnostic yield in open access endoscopy has been evaluated which generally support the effectiveness and efficiency of open access endoscopy. With a few exceptions, diagnostic yield studies have not been performed in open access endoscopy for more specific conditions. Therefore, we conducted a study to determine the efficiency of open access endoscopy in the detection of microscopic colitis as compared to traditional referral via a gastroenterologist.

NAFLD recurrence in liver transplant recipients.

Background And Aims: Nonalcoholic fatty liver disease (NAFLD) is a common indication for liver transplantation and can recur in the graft. To describe this recurrence, we performed a cohort study of individuals undergoing liver transplantation for NAFLD-related cirrhosis between 1993 and 2007. Predictors of NAFLD recurrence and outcomes in this cohort were also studied.

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.
