Development and validation of an ultra-high performance liquid chromatography-tandem mass spectrometry method to measure creatinine in human urine.
cope with both a high sample throughput and a low volume of sample is still of interest. In answer to these challenges, a fast and accurate ultra-high performance liquid chromatography-tandem mass ...
A simple multi-residue method for the determination of pesticides in fruits and vegetables using a methanolic extraction and ultra-high-performance liquid chromatography-tandem mass spectrometry: optimization and extension of scope.
a methanolic solution, the sample is simply diluted before the separation and detection by ultra-high-performance liquid chromatography and MS / MS detection for quantitative and confirmatory purposes. The ...
Fast and discriminative CoSYPS detection system of viable Salmonella spp. and Listeria spp. in carcass swab samples.
namely swab sample enrichment, SYBR ®Green qPCR detection of Salmonella spp. and Listeria spp., isolation and confirmation of the detected strain, was validated on beef carcass swabs. To perform the ...
Comparative study of seven commercial kits for human DNA extraction from urine samples suitable for DNA biomarker-based public health studies.
yield were also tested for the presence of PCR inhibitors. Further comparisons were performed regarding the sampling time and the storage conditions. Finally, as a proof-of-concept, an important gene ...
Validation of a sensitive DNA walking strategy to characterise unauthorised GMOs using model food matrices mimicking common rice products
characterising the transgene flanking regions, using DNA walking. Here, the DNA walking performance has been thoroughly tested for the first time, regarding the targeted DNA quality and quantity. Several assays, ...
The European COPHES/DEMOCOPHES project: towards transnational comparability and reliability of human biomonitoring results.
all over the world served as reference laboratories. Web conferences after each external quality assessment exercise functioned as a new and effective tool to improve analytical performance, to build ...
Determination of caramel colorants' by-products in liquid foods by ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).
liquid foods, an ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC- MS / MS) method was developed and sample preparation was divided into two analytical strategies depending on ...
Lessons learned from a textbook outbreak: EHEC-O157:H7 infections associated with the consumption of raw meat products, June 2012, Limburg, Belgium.
O157: H7 infections were reported to the public health authorities of Limburg. METHODS: We performed a case-control study, a trace back/forward investigation and compared strains isolated from human cases ...
Banana infecting fungus, Fusarium musae, is also an opportunistic human pathogen: are bananas potential carriers and source of fusariosis?
and terbinafine was the most effective drug. Additional clinical F. musae strains were searched by performing BLAST queries in GenBank. Eight strains were found, of which six were keratitis cases from ...
