Multi-dye residue analysis of triarylmethane, xanthene, phenothiazine and phenoxazine dyes in fish tissues by ultra-performance liquid chromatography-tandem mass spectrometry.
0.25ngg(-1) for all dyes, with a signal-to-noise ratio of at least 10/1. This is at least 5 to 10 times lower than previous published methods. Limits of detection were all <0.1ngg(-1). Precision and trueness ...
Characterization of suspected illegal skin whitening cosmetics.
detected were clobetasol propionate and hydroquinone, which represent a serious health risk when repeatedly and abundantly applied to the skin. Health Topics: Food consumption and food safety Consommation ...
Hair mercury and urinary cadmium levels in Belgian children and their mothers within the framework of the COPHES/DEMOCOPHES projects.
children’s urine was detected at a geometric mean concentration of respectively 0.21 and 0.04 μg/l. For both biomarkers, levels measured in the mothers and their child were correlated. While the urinary ...
SYBR®Green qPCR Salmonella detection system allowing discrimination at the genus, species and subspecies levels.
Sensitivity and Specificity Staining and Labeling Abstract: In this work, a three-level Salmonella detection system based on a combination of seven SYBR ®Green qPCR was developed. This detection system ...

MLVA as a tool for public health surveillance of human Salmonella Typhimurium: prospective study in Belgium and evaluation of MLVA loci stability.
techniques like multiple-locus variable-number of tandem repeats analysis (MLVA), which allow earlier detection and confinement of outbreaks. Here, a surveillance study, including phage typing, antimicrobial ...
Development and validation of qualitative SYBR®Green real-time PCR for detection and discrimination of Listeria spp. and Listeria monocytogenes.
and the “Definition of minimum performance requirements for analytical methods of GMO testing”. The developed assays target the iap, prs and hlyA genes that belong to or neighbour the virulence cluster ...
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 ...
