Occurrence of microcystin congeners in surface waters and food in Belgium as a source of exposure to humans
group worldwide, the microcystin congeners (MC s). After method validation, the quantitative UHPLC- MS / MS approaches were applied to Belgian samples to characterize potential human exposure sources in ...
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
Publication Type: Dissertation Authors: Bert Bogaerts Source: Ghent University, Gh, p.250 (2021) Keywords: bioinformatics public health VALIDATION whole-genome sequencing Abstract: Whole genome ...
Development of a genoserotyping system for the identification of Salmonella serotypes
of the results in a database to improve the Salmonella surveillance in Belgium. The 4 modules and the DSS were validated by comparison with the classical method, including more than 1300 strains and ...
DETERMINATION OF SENSITIZING AND IRRITATING LEACHABLES IN MENSTRUAL HYGIENE PRODUCTS
included as internal standard. Validation of the UPLC- TQMS method addressed selectivity, linearity, precision, trueness and accuracy. Out of the 15 investigated MHP s, 6 were found to leak 5 sensitizing and ...
DETERMINATION OF ALLERGENIC FRAGRANCE INGREDIENTS IN FEMININE ABSORBENT HYGIENE PRODUCTS AND LUBRICANTS
lubricants, fragrances are used freely. Although 26 allergenic fragrances are documented as they are known to cause allergic contact dermatitis (ACD). Aim: The aim is to develop a valid method to determine 24 ...
Fusarium, clinical relevance and mass spectrometry methods for identification, using strains of the Belgian fungal culture collection BCCM/IHEM
isolated from patients, were re-identified by multilocus DNA marker sequencing and phylogeny. The remaining 289 validated strains, comprising 40 different species, were of great value: (i) Analysis of the ...
Study of the possible migration risks of food contact materials for children under 3 years
Monitoring and quantification of these compounds was done using GC- and LC-QqQ- MS methods, for which several validation parameters were determined (sensitivity, selectivity, linearity, accuracy, precision, ...
Determination of lawasone and paraphenylenediamine in henna tattoos and hair dyes through UPLC-PDA
presence of the skin sensitizer paraphenylenediamine (PPD). Aim: To develop and validate a fast UPLC- PDA method to simultaneously determine lawsone and PPD in henna tattoos and hair dyes with the purpose to ...
