Several current diseases are associated with an increase in the oxidation of HDL, which is likely to impair their functionality. Our aim was to identify whether oxidation could change the protective effect of HDL against the deleterious effect on vasoreactivity induced by oxidative stress. HDL from healthy subjects were oxidized in vitro by Cu(2+), and the(More)
BACKGROUND Chronic allograft nephropathy (CAN), which remains the main cause of graft loss after kidney transplantation, is still poorly understood. Because anti-HLA antibodies may be involved in the pathogenesis of CAN, this study was performed to look for donor-specific antibodies (DSA) fixed onto renal transplants with CAN. METHODS DSA were identified(More)
AIMS/HYPOTHESIS In addition to its efficacy in reducing LDL-cholesterol, rosuvastatin has been shown to significantly decrease plasma triacylglycerol. The use of rosuvastatin may be beneficial in patients with type 2 diabetes, who usually have increased triacylglycerol levels. However, its effects on the metabolism of triacylglycerol-rich lipoproteins in(More)
The assessment of the microsatellite instability (MSI) status in colorectal cancers is presently warranted for three reasons: 1) as a screening tool for hereditary nonpolyposis colorectal cancer, 2) as a prognostic marker, and 3) as a potential predictive factor of chemotherapy response. The aim of this study was to evaluate, on a large scale with tissue(More)
The aim of this study was to assess the feasibility of detecting anti-HLA antibodies in eluates from needle core biopsies of renal transplants with chronic allograft nephropathy. Two methods of screening, the enzyme-linked immunosorbent assay (ELISA) and flow cytometry (FlowPRA) were compared. Twenty renal transplants with CAN were removed after(More)
Microsatellite instability has been proposed as an alternative pathway of colorectal carcinogenesis. The aim of this study was to evaluate the interest of immunohistochemistry as a new tool for highlighting mismatch repair deficiency and to compare the results with a PCR-based microsatellite assay. A total of 100 sporadic proximal colon adenocarcinomas were(More)
AIMS The aim of this study was to assess the independent value of pathological criteria in the diagnosis of mismatch repair (MMR)-defective sporadic colorectal cancers. METHODS AND RESULTS Resected colorectal adenocarcinomas (n = 273) were reviewed in order to identify a number of specific morphological features of MMR-defective carcinomas. Of the 273(More)
The Inhibitor of Apoptosis Protein (IAP) family includes several critical cell death inhibitors, the expression of which could be involved in colorectal carcinogenesis. Among them, c-IAP1 and c-IAP2 expression has never been investigated in colorectal cancer. The present study was designed to determine whether expression of both IAPs was related to(More)
The aim of this study was to determine the expression of transforming growth factor-beta (TGFbeta)-1 and type I TGFbeta-receptor on sequential biopsies from renal transplants with and without chronic allograft nephropathy. Twenty-four renal transplant recipients entered the study. They underwent sequential biopsies performed before (T1: 1.44 +/- 1.2 months)(More)
