The plasma lipid transfer proteins promote the exchange of neutral lipids and phospholipids between the plasma lipoproteins. Cholesteryl ester transfer protein (CETP) facilitates the removal of cholesteryl esters from HDL and thus reduces HDL levels, while phospholipid transfer protein (PLTP) promotes the transfer of phospholipids from triglyceride-rich(More)
Although Th17 cells are known to promote tissue inflammation and autoimmunity, their role during cancer progression remains elusive. Here, we showed that in vitro Th17 cells generated with the cytokines IL-6 and TGF-β expressed CD39 and CD73 ectonucleotidases, leading to adenosine release and the subsequent suppression of CD4(+) and CD8(+) T cell effector(More)
Fibrate treatment in mice is known to modulate high density lipoprotein (HDL) metabolism by regulating apolipoprotein (apo)AI and apoAII gene expression. In addition to alterations in plasma HDL levels, fibrates induce the emergence of large, cholesteryl ester-rich HDL in treated transgenic mice expressing human apoAI (HuAITg). The mechanisms of these(More)
Computed tomography remains strongly underused in plant sciences despite its high potential in delivering detailed 3D phenotypical information because of the low X-ray absorption of most plant tissues. Existing protocols to study soft tissues display poor performance, especially when compared to those used on animals. More efficient protocols to study plant(More)
Nowadays, most patients who undergo colorectal surgery are discharged early. An early predictor of septic complications could avoid readmissions and decrease morbidity. CRP could be a good predictor allowing a safe discharge. A prospective, observational study was conducted from November 2007 to October 2008. All patients who underwent elective colorectal(More)
PURPOSE To compare pure molecular diffusion, D, perfusion-related diffusion, D*, and perfusion fraction, f, determined from diffusion-weighted (DW) magnetic resonance (MR) imaging on the basis of the intravoxel incoherent motion (IVIM) theory in patients with type 2 diabetes with and without liver steatosis. MATERIALS AND METHODS This prospective study(More)
OBJECTIVE Increasing HDL levels is a potential strategy for the treatment of atherosclerosis. METHODS AND RESULTS ITX5061, a molecule initially characterized as a p38 MAPK inhibitor, increased HDL-C levels by 20% in a human population of hypertriglyceridemic subjects with low HDL levels. ITX5061 also moderately increased apoA-I but did not affect VLDL/LDL(More)
PURPOSE To validate a triple-echo gradient-echo sequence for measuring the fat content of the liver, by using hydrogen 1((1)H) magnetic resonance (MR) spectroscopy as the reference standard. MATERIALS AND METHODS This prospective study was approved by the appropriate ethics committee, and written informed consent was obtained from all patients. In 37(More)
The nuclear hormone receptor constitutive androstane receptor (CAR, NR1I3) regulates detoxification of xenobiotics and endogenous molecules, and has been shown to be involved in the metabolism of hepatic bile acids and cholesterol. The goal of this study was to address potential effects of CAR on the metabolism of HDL particles, key components in the(More)
CONTEXT Recently, it has been shown in the general population that an allele in the adiponutrin (PNPLA3) gene was strongly associated with increased liver fat content (LFC), independently of visceral adiposity and insulin resistance. OBJECTIVE In this study, we set out to determine whether LFC, evaluated using (1)H-MR spectroscopy, was associated with(More)
