Identification of fungal isolates by MALDI-TOF mass spectrometry in veterinary practice: validation of a web application.
a reliable method to identify fungal isolates. The success of this approach relies on the availability of exhaustive databases, but the latter were built with a focus on human pathogens. We assessed a large ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
and that levels of several compounds with known /suspected endocrine disrupting properties could be detected or quantified in human placenta samples. The results therefore suggest that fetal exposure to ...
Prioritizing substances of genotoxic concern for in-depth safety evaluation using non-animal approaches: The example of food contact materials.

Assessment of estrogenic compounds in paperboard for dry food packaging with the ERE-CALUX bioassay
a bioanalytical tool to investigate estrogenic activities of paperboard food packaging and its characteristics, including recycling rate and printing ink. A “worst case” scenario with full extraction is compared to ...
Shifting national surveillance of Shigella infections toward geno-serotyping by the development of a tailored Luminex assay and NGS workflow.
combining five genetic markers for species identification with 11 markers for serotype prediction for S. sonnei and S. flexneri isolates. Using a test panel of 254 clinical samples, this assay has ...
