Occurrence of microcystin congeners in surface waters and food in Belgium as a source of exposure to humans
also identified in the waterbody samples to better characterize the cyanobacteria blooms. Algal-based food supplements were also identified as a potential exposure source. The presence of toxin-producing ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
Ultimately, a validation of the method is still necessary in order to obtain a precise limit of detection based on the analysis of a large dataset of samples. Moreover, other technologies can still be ...
Development of a data-intensive centralized system for surveillance and outbreak investigation of bacterial pathogens using whole-genome sequencing
(Neisseria meningitidis, Shiga toxin-producing Escherichia coli, and Mycobacterium tuberculosis) to provide a more efficient and powerful alternative to the conventional molecular biology-based methods. ...
Chemical and toxciological characterization of e-liquid cigarettes
e-liquid refills. First, a comprehensive literature search was performed to obtain an overview about the chemical composition of the e-liquids and the analytical methods used for their detection. Although the ...
Development of a genoserotyping system for the identification of Salmonella serotypes
detection of molecular markers or on the analysis of sequencing data, are described in the scientific literature. Based on a critical review of some of these techniques, the Multiplex Oligonucleotide ...
Genotoxic evaluation of the liquids present in electronic cigarettes
vitro or in vivo data (i.e. Ice Ice Baby, Candy Shop) were studied in the Ames test and the in vitro micronucleus test. [Results and discussion] Based on the predictions obtained with the in silico ...
Fusarium, clinical relevance and mass spectrometry methods for identification, using strains of the Belgian fungal culture collection BCCM/IHEM
development of a new identification method for mold infections which is directly applicable on clinical samples and relies upon the detection of species- and genus-specific peptides using tandem mass ...
Development of molecular tools for rapid detection and quantification of indoor airborne molds to assess their impact on public health
a specific ITS-based SYBR ®green real-time PCR (qPCR) assay for Aspergillus versicolor, a species frequently observed in indoor air and known to be allergenic. Additionally, an ITS-based qPCR assay was ...
Study of the possible migration risks of food contact materials for children under 3 years
detected based on this library search. In Chapter 4.2, unidentified peaks were further investigated by advanced mass spectrometric techniques, such as GC-(EI) TOF- MS and GC-(APCI) QTOF- MS, to specifically ...
Detection and risk evaluation of counterfeit medicines based on physico-chemical properties: the fingerprint and chemometrics approach
since even very low concentrations of API could be detected while these particular samples are classified as placebo based on other types of fingerprints. Illegal slimming aids do not only pose a threat ...
