Une nouvelle stratégie de synthèse pour la préparation de N-hydroxyphtalimides par le biais de la cycloaddition [2+2+2] entre le maléimide et des α,ω-diynes catalysée par le système [IrCl(COD)]2/DPPE ou [RhCl(COD)]2/DPPE...

The increasing interest for potential health effects of nanoparticles justifies to assess human exposure in various environment. The NANOP project aims at characterising nanoparticle levels and their spatial and temporal...
-
In this paper we revisit local feature detectors/descriptors developed for 2D images and extend them to the more general framework of scalar fields defined on 2D manifolds. We provide methods and tools to detect and desc...
-
The importance we attach to 3D is probably related to the manner we perceive the world. Humans in general seem attracted by all types of representations that are close to their perception. They represent objects and pres...

A wastewater treatment system including a screen, a vermifilter, macrophytes ponds, and constructed wetlands has been built after a pig housing on slatted-floor. The aims were, all at once, to recycle water for excretion...
-
Purpose: The purpose of this paper is to evaluate whether the new (comprehensive) concept of competence and the competence-based education approach are being used in, and perceived as being fruitful for, academic educati...
-
SNARE proteins contribute to specific recognition between transport vesicles and target membranes and are required for fusion of membranes. The SNARE Vti1p is required for several transport steps between late Golgi, endo...
-
Mining sites are usually sources of metal pollution many years after closure. Specific geo-chemical phenomena such as acid drainage contribute to an increase of environmental impacts, especially if remediation measures w...

We evaluated the effects of infection with Haemonchus contortus on feed intake, digestibility, fecal egg count, circulating eosinophils, and packed cell volume in Creole kids differing in genetic resistance (susceptible,...
-
Sex hormone-binding globulin (SHBG) is the main transport binding protein for sex steroid hormones in plasma and regulates their accessibility to target cells. Plasma SHBG is secreted by the liver under the control of ho...
-
The ion-pair concept was applied on complex haemoglobin hydrolysates to extract two opioid peptides, LVV-haemorphin-7 and VV-haemorphin-7, in an aqueous/octan-1-ol micro-extraction system in the presence of alkyl-sulfoni...

The Repeat in Toxin (RTX) motif is a tandemly repeated calcium-binding nonapeptide sequence present in proteins that are secreted by the type I secretion system (T1SS) of Gram-negative bacteria. Here, we have characteriz...

Prion diseases are fatal, neurodegenerative disorders in humans and animals and are characterized by the accumulation of an abnormally folded isoform of the cellular prion protein (PrP(C)), denoted PrP(Sc), which represe...
-
Prions are infectious proteins responsible for a group of fatal neurodegenerative diseases called transmissible spongiform encephalopathies (TSEs), or prion diseases. In mammals, prions reproduce themselves by recruiting...
