On-line solid-phase extraction with ultra performance liquid chromatography and tandem mass spectrometry for the detection of nicotine, cotinine and trans-3'-hydroxycotinine in urine to strengthen human biomonitoring and smoking cessation studies.
spectrometry (UPLC- MS / MS) for the simultaneous detection of nicotine, cotinine and trans-3’-hydroxycotinine in human urine. The advantages of both on-line SPE (speed, automation, less labor intensive) coupled ...
Prevalence and levels of Bacillus cereus emetic toxin in rice dishes randomly collected from restaurants and comparison with the levels measured in a recent foodborne outbreak.

Dietary intake of artificial sweeteners by the Belgian population.
liquid chromatography with mass spectrometric detection. Concentrations of sweeteners in various food matrices and table-top sweeteners were determined and mean positive concentration values were included ...
High prevalence of vitamin D deficiency in pregnant women: a national cross-sectional survey.
consequences for the mother and the offspring. A targeted screening strategy to detect and treat women at high risk of severe vitamin D deficiency is needed in Belgium and in Europe. Health Topics: Food ...
Neonatal thyroid-stimulating hormone concentrations in Belgium: a useful indicator for detecting mild iodine deficiency?
deficient, the frequency of neonatal TSH concentrations above 5 mU/L was very low, suggesting that the neonatal TSH threshold proposed for detecting iodine deficiency needs to be re-evaluated. Although ...
Follow-up of the Bacillus cereus emetic toxin production in penne pasta under household conditions using liquid chromatography coupled with mass spectrometry.
outbreak-related Bacillus cereus emetic strains were investigated for their growth and cereulide production potential in penne pasta at 4, 8 and 25 °C during 7-day storage. Cereulide production was detected and ...
Rapid method for the confirmatory analysis of chrysoidine in aquaculture products by ultra-performance liquid chromatography-tandem mass spectrometry.

A theoretical introduction to "combinatory SYBRGreen qPCR screening", a matrix-based approach for the detection of materials derived from genetically modified plants.
Genetically Modified polymerase chain reaction Abstract: The detection of genetically modified (GM) materials in food and feed products is a complex multi-step analytical process invoking screening, ...
Microbiological and molecular investigation of an increase of human listeriosis in Belgium, 2006-2007.
