Huntington's disease (HD) is one of an increasing number of neurodegenerative disorders caused by a CAG/polyglutamine repeat expansion. Mice have been generated that are transgenic for the 5' end of the human HD gene carrying (CAG)115-(CAG)150 repeat expansions. In three lines, the transgene is ubiquitously expressed at both mRNA and protein level.(More)
Huntington's disease (HD) is one of an increasing number of human neurodegenerative disorders caused by a CAG/polyglutamine-repeat expansion. The mutation occurs in a gene of unknown function that is expressed in a wide range of tissues. The molecular mechanism responsible for the delayed onset, selective pattern of neuropathology, and cell death observed(More)
The mechanism by which an elongated polyglutamine sequence causes neurodegeneration in Huntington's disease (HD) is unknown. In this study, we show that the proteolytic cleavage of a GST-huntingtin fusion protein leads to the formation of insoluble high molecular weight protein aggregates only when the polyglutamine expansion is in the pathogenic range.(More)
BACKGROUND Upregulation of Th1 associated intrahepatic cytokines in chronic hepatitis C virus (HCV) infection should lead to a significant non-specific cellular immune response, a prerequisite for viral clearance. However, to date, the role of this non-specific response in HCV has been understudied. AIMS To analyse the intrahepatic macrophage activity in(More)
Laparotomy has been the favored approach regarding surgical management of small bowel obstruction (SBO); however, laparoscopy may offer improved outcomes. Patients undergoing laparoscopic lysis of adhesions (LOA) at our institution for SBO will have lower postoperative morbidity and 30-day mortality. Patients undergoing LOA at our institution, from 2000 to(More)
BACKGROUND Vancomycin is considered the drug of choice for methicillin-resistant Staphylococcus aureus infection; however, it has also been linked with nephrotoxicity in the past, sometimes leading to its substitution with linezolid. We hypothesized that patients treated with vancomycin for gram-positive (GP) infections would have an increased incidence of(More)
The faithful recovery of the base sequence in automatic DeoxyriboNucleic Acid (DNA) sequencing fundamentally depends on the underlying statistics of the DNA electrophoresis time series. Current DNA sequencing algorithms are heuristic in nature and modest in their use of statistical information. In this paper, a formal statistical model of the DNA time(More)
Using the post-hypoxic mouse method of assay, values for erythropoietin in the plasma of patients with chronic renal failure were equal to, or greater than, normal values. Results suggest that the source of erythropoietin may be primarily extrarenal. Normal renal tissue, provided in the assay by the intact mouse, is required for activation of the hormone.(More)
BACKGROUND As obesity and type II diabetes continue to rise, bariatric surgery offers a solution, but few long-term studies are available. The purpose of this study was to evaluate the long-term outcomes of diabetic patients after gastric bypass. MATERIALS AND METHODS This was a retrospective cohort study of all diabetic patients undergoing gastric bypass(More)
