Brominated flame retardants in Belgian foodstuffs- recent evaluation by a novel UPLC-MS/MS method
system coupled to a Xevo- TQ-S mass spectrometer. Sample preparation protocol consisted of a QuEChERS-based extraction followed by two parallel clean-up procedures. Column chromatography with acidified ...
Scientific Opinion on the Risks for human health related to the presence of 3- and 2-monochloropropanediol (MCPD), and their fatty acid esters, and glycidyl fatty acid esters in food
high exposure (P95) values were 0.3-2.6, 0.2-1.2 and 0.2-2.1. Animal studies show extensive hydrolysis of esterified 3- MCPD and glycidol following oral administration; esterified and free forms were ...
Hospitalisations at the end of life in four European countries: a population-based study via epidemiological surveillance networks.
follow-back study via Sentinel Networks of general practitioners (GP s) in Belgium, the Netherlands, Italy and Spain. Using a standardised form, GP s recorded the care in the last 3 months of life of every ...
Migration of photoinitiators from cardboard into dry food: evaluation of Tenax® as a food simulant.
paperboard for the following photoinitiators: benzophenone (BP), 4,4’-bis(diethylamino)benzophenone (DEAB), 2-chloro-9H-thioxanthen-9-one (CTX), 1-chloro-4-propoxy-9H-thioxanthen-9-one (CPTX), ...
Validation of a Sampling Method to Collect Exposure Data for Central-Line-Associated Bloodstream Infections.
Tuesdays provided the best estimations. In the linear mixed model, the observed CLD count was the best predictor for a smaller percentage error. The following sampling strategies provided an estimate within ...

Analytical performances of food microbiology laboratories- critical analysis of 7 years of proficiency testing results
main causes of analytical errors and suggests practical solutions to avoid them, in an educational purpose. The observations support the hypothesis that regular participation to PT, when followed by ...
Synthesis and anti-tubercular activity of N(2)-arylbenzo[g]isoquinoline-5,10-dione-3-iminium bromides.
anilines with 2-(bromomethyl)-3-(cyanomethyl)-1,4-dimethoxynaphthalene. Following the biological evaluation, N(2)-(4-chlorophenyl)-5,10-dioxobenzo[g]isoquinoline-3(2H)-iminium bromide (MIC = 1.16 μM, CC50 ...
Comparison of three development approaches for Stationary Phase Optimised Selectivity Liquid Chromatography based screening methods Part II: A group of structural analogues (PDE-5 inhibitors in food supplements).
