The aim of this study was to assess the interindividual variability of chylomicron beta-carotene response to a pharmacological load of beta-carotene in the population, to identify the mechanisms responsible for this variability, and to evaluate its consequences on beta-carotene status and metabolism. The variability, as estimated by the 3-h chylomicron(More)
BACKGROUND AND AIM Plasma cholesterol efflux capacity is stimulated during postprandial (PP) hypertriglycerdemia. Plasma cholesteryl ester transfer protein (CETP) and phospholipid transfer protein (PLTP) are the key proteins in lipoprotein metabolism and remodelling, but their role during the PP cholesterol efflux process remains indeterminate. The aim of(More)
This study provides with original data sets on the physiology of the unicellular diazotrophic cyanobacterium Crocosphaera watsonii WH8501, maintained in continuous culture in conditions of obligate diazotrophy. Cultures were exposed to a 12:12 light-dark regime, representative of what they experience in nature and where growth is expected to be balanced.(More)
Portal biliopathy (PB) refers to the biliary abnormalities of the biliary ducts observed in patients with extrahepatic portal hypertension. Although majority of patients are asymptomatic, approximately 20% of these patients present with biliary symptoms (pain, pruritus, jaundice, cholangitis). The pathogenesis of PB is uncertain but compression by dilated(More)
Microscopical and molecular analyses were used to investigate the diversity and spatial community structure of spring phytoplankton all along the estuarine gradient in a macrotidal ecosystem, the Baie des Veys (eastern English Channel). Taxa distribution at high tide in the water column appeared to be mainly driven by the tidal force which superimposed on(More)
Despite advances in surgical techniques, anesthesia and perioperative care, which became safer and accessible to a higher proportion of high-risk patients, major surgery remains morbid with a lot of patients not recovering their previous capacity. Indeed surgery is a physiological stress and decreases functional capacity in the postoperative period. A(More)
Tumor involvement of the inferior vena cava (IVC) by hepatobiliary, pancreatic or duodenal malignancies can compromise adequate resection. However, radical resection with negative histological margins remains the only chance of cure. Various techniques are used for venous reconstruction, using a prosthetic graft interposition in most of the cases. However,(More)
