Polycyclic aromatic hydrocarbons (PAHs), mainly formed by incomplete anthropogenic organic matter combustion, are ubiquitous in the environment. To assess milk PAH contamination sources, milk samples were collected from the tank milk at farms located near potential contaminating emission sources such as cementworks, steelworks, and motorways. PAH analyses(More)
The aim of this work was to study the transfer through the intestinal barrier of two polycyclic aromatic hydrocarbons (PAHs) (benzo[a]pyrene and phenanthrene) and a dioxin (2,3,7,8-tetrachlorodibenzo-para-dioxin) which differed in their physicochemical properties. Both in vitro and in vivo assays were performed. For the in vitro study, Caco-2 cells,(More)
Polycyclic aromatic hydrocarbons (PAHs) and dioxins are lipophilic organic pollutants occurring widely in the terrestrial environment. In order to study the PAHs and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) transfer in the food chain, pigs have been fed with milk mixed either with 14C-phenanthrene, with 14C-benzo[a]pyrene or with 14C-TCDD. The analysis of(More)
The aim of this study was to determine the tissue distribution of 17 PCDD/Fs following the chronic ingestion of contaminated milk in rats and to assess the "target tissue/milk" BioConcentration Factors (BCFs) of these molecules. Contaminated milk, collected in a polluted area, has been incorporated into the diet of male rats at a low dose (31 pg(More)
On the request of the Belgian Health Council, the authors performed a systematic review of the available evidence in the literature and in expert panel reports, with regard to a possible carcinogenic effect of dichlorvos. Following the evaluation procedure developed by IARC, they first concluded that dichlorvos should be classified as a possible carcinogen(More)

Many nursing practices and treatments that were once standard have fallen out of favour or been discredited. For example, in the 1980s egg white was still being used to treat pressure ulcers, with 'fairly catastrophic' effects. A look back at nursing's recent past is a good remedy for misplaced nostalgia.
This article was written by four French hospital director students at the Ecole des Hautes Etudes en Santé Publique (EHESP-School of Public Health) from a study conducted jointly with students at the Grenoble School of Management to present an international overview of hospital procurement methods in ten countries. An analysis of these methods showed that(More)
