COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
method was developed using ultra-high performance liquid chromatography with diode array detector (DAD). Furthermore, selection of orthogonal wavelengths was made to extract maximum information from the ...
Spectroscopic approaches for conformity analysis of e-liquids
Therefore, it is necessary to monitor the compositions of the products on the market and conduct surveillance studies. In Belgium this is performed under the coordination of the Federal Public Service of ...
Multidimensional Chromatographic Fingerprinting Combined with Chemometrics for the Identification of Regulated Plants in Suspicious Plant Food Supplements.
were recorded using ultra-high-performance liquid chromatography (UHPLC) coupled with diode array detection (DAD). Chemometric modelling was performed by partial least squares-discriminant analysis (PLS- ...
Factors underlying COVID-19 booster vaccine uptake among fully vaccinated adults in Belgium
individuals who received their primary course. A first COVID-19 vaccine booster campaign was performed in winter of 2021 (age ≥ 18 years) and a second campaign for (age ≥ 50 years) in autumn of 2022. During ...
The evolving personal, professional and physical impact on healthcare professionals during three COVID-19 waves: A cross-sectional study
Methods A repeated cross-sectional study was performed with eight measurement points between April 2020 and September 2021 in Belgium. Participants were asked how frequently (on a scale of 0–10) they ...
Hepatitis E virus in pork meat products and exposure assessment in Belgium.
HEV consumer exposure in a Belgian context. Two basic assessments were performed in a ‘worst-case’ scenario setting: one solely focusing on the contamination level of the product itself (ingredients and ...
Mental Distress and Its Contributing Factors Among Young People During the First Wave of COVID-19: A Belgian Survey Study
discriminate mental distress cases from non-cases. Bivariate and multivariable logistic regression analyses were performed to evaluate possible predictors of mental distress, including demographics, chronic ...
Targeted Chromosomal Barcoding Establishes Direct Genotype-Phenotype Associations for Antibiotic Resistance in Mycobacterium abscessus.
analysis performed in independent M. abscessus strains and by independent researchers. Antimicrobial resistance (AMR) threatens the effective prevention and treatment of an ever-increasing range of ...
Development of Digital Droplet PCR Targeting the Influenza H3N2 Oseltamivir-Resistant E119V Mutation and Its Performance through the Use of Reverse Genetics Mutants.
Furthermore, reverse genetics viruses carrying this mutation were created to test the performance of the RT-ddPCR assay and compare it to the standard phenotypic NA assay. We also discuss the advantage of using ...
Implementation of MALDI-TOF Mass Spectrometry to Identify Fungi From the Indoor Environment as an Added Value to the Classical Morphology-Based Identification Tool
molds is generally performed by microscopy. This method has, however, some limitations as it requires mycologists with high expertise while identification is often limited to the genus level. Therefore, ...
