The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
CBD-liquids investigated in this study, only 30% of the samples contained an amount of CBD that was within 10% deviation of the label claim. Moreover, the CBD e-liquids labelled “full/broad spectrum” consisted ...
Homologous versus heterologous prime-boost COVID-19 vaccination: impact on clinical severity of Omicron among hospitalized COVID-19 patients in Belgium
Microbiology and Infectious Diseases (2023) Abstract: Background We investigated the real-world effectiveness of a heterologous versus homologous primeboost vaccination scheme against severe clinical outcomes of ...
The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV
applying accuracy profiles and conforming to ISO17025. None of the analysed samples exceeded the legal limit for the total amount of ∆9- THC present. However, of the 20 CBD-liquids investigated in this ...
Investigating COVID-19 Vaccine Impact on the Risk of Hospitalisation through the Analysis of National Surveillance Data Collected in Belgium.
vaccination campaign against SARS-CoV-2 started in January 2021 in Belgium. In the present study, we aimed to use national hospitalisation surveillance data to investigate the recent evolution of vaccine impact ...
Incidence and Risk Factors of COVID-19 Vaccine Breakthrough Infections: A Prospective Cohort Study in Belgium.
Abstract: The objective of this study was to investigate the incidence and risk factors associated with COVID-19 vaccine breakthrough infections. We included all persons ≥18 years that had been fully ...
Deepening of In Silico Evaluation of SARS-CoV-2 Detection RT-qPCR Assays in the Context of New Variants
proper detection of the virus. In the present study, 11 primers and probe sets investigated during the first study were evaluated again with 84,305 new SARS-CoV-2 unique genomes collected between June 2020 ...
Chemical and toxciological characterization of e-liquid cigarettes
PhD thesis was therefore to first determine the chemical composition of the liquids used in e-cigarettes (e-liquid) and next to investigate toxicological aspects of flavouring substances present in ...
Identification of Flavouring Substances of Genotoxic Concern Present in E-Cigarette Refills
investigated in silico with two complementary (quantitative) structure-activity relationship ((Q) SAR) models (Derek Nexus, Sarah Nexus). In total, 57 flavouring components were identified with a structural ...
A new approach to define acceptance limits for hematology in external quality assessment schemes.
their corresponding assigned value (U-scores) was modeled by means of an adaptation of Thompson’s “characteristic function”. Quantile regression was used to investigate the percentiles of the U-scores for ...
Zona pellucida gene mRNA expression in human oocytes is related to oocyte maturity, zona inner layer retardance and fertilization competence.
Presence of ZP3 protein in CC and oocytes was investigated using immunocytochemistry. Data were analysed using one-parametric and multivariate analysis and were corrected for the potential impact of patient ...
