Development of the coronary arteries in a murine model of transposition of great arteries.
2003
Transposition of great arteries in humans is associated with a wide spectrum of coronary artery patterns. However, no information is available about how this pattern diversity develops. We have studied the development of the coronary arteries in mouse embryos with a targeted mutation of perlecan, a mutation that leads to ventriculo-arterial discordance and complete transposition in about 70% of the embryos. The perlecan-deficient embryos bearing complete transposition showed a coronary artery pattern consisting of right and left coronary arteries arising from the morphologically dorsal and ventral sinuses of Valsalva, respectively. The left coronary artery gives rise to a large septal arter…
Thrombotic thrombocytopenic purpura (TTP) leading to pseudotumour's autoimmune pancreatitis (AIP): A case report
2012
International audience; Introduction: Autoimmune pancreatitis is an idiopathic inflammatory disease that produces pancreatic masses and ductal strictures. This benign disease can be associated with extrapancreatic manifestations including cholangitis, sialadenitis, inflammatory bowel disease or retroperitoneal fibrosis, mediastinal adenopathy, interstitial nephritis mainly due to immunoglobulin G4 (Ig G4), and occasional association with other auto-immune diseases. Observation: We report a 57-year-old woman who developed thrombotic thrombocytopenic purpura (UP) and pseudo-tumour's seronegative autoimmune pancreatitis (ATP) type 1. The patient was initially treated with pulse corticosteroids…

Modelling the removal and reversible immobilization of murine noroviruses in a Phaeozem under various contamination and rinsing conditions
2018
International audience; Enteric viruses entering the soil with contaminated irrigation water can reach groundwater or be internalized in plants through their roots without being inactivated. Their fate in the soil depends on the virus, the soil and the soil solution. In order to write a mathematical model suitable for a Calcaric Phaeozem, we investigated the removal of murine norovirus and reversible immobilization in aggregate columns according to a saturation procedure, conditions between contamination and rinsing time, temperature and soil solution. Viruses were quantified before and after 0.45‐μm filtration with an RT‐qPCR (real‐time polymerase chain reaction). Experimental results supp…
The effect of carvacrol on enteric viruses.
2014
Carvacrol, a monoterpenic phenol, is said to have extensive antimicrobial activity in a wide range of food spoilage or pathogenic fungi, yeast and bacteria. The aim of this study was to assess its antiviral activity on norovirus surrogates, feline calicivirus (FCV), murine norovirus (MNV), and hepatitis A virus (HAV), as well as its potential in food applications. Initially, different concentrations of carvacrol (0.25, 0.5, 1%) were individually mixed with each virus at titers of ca. 6-7 log TCID50/ml and incubated 2h at 37°C. Carvacrol at 0.5% completely inactivated the two norovirus surrogates, whereas 1% concentration was required to achieve ca. 1 log reduction of HAV. In lettuce wash wa…
