Assessing particle count in electron microscopy measurements of nanomaterials to support regulatory guidance
practicesfor measurements but lacks requirements on how many particles to measure. Using transmissionelectron microscopy data of nanomaterials, a strategy based on repeated subsampling is proposedto establish, ...
Ketamine, a new (or old) kid on the block: A comprehensive three-year spatio-temporal study in Belgium through wastewater-based epidemiology
a temporal dataset from daily IWW samples from Leuven (n = 399) and Brussels (n = 285) in 2021 and 2022 was evaluated using time series analysis. Measured concentrations of ketamine, norketamine and ...
Residential greenness and pollen exposure across gestational trimesters in relation to preschool wheezing: Results for the PIPO birth cohort
data from the PIPO birth cohort (n = 860). Wheezing was reported biannually between 18 and 48 months of age. Residential greenness was measured with Normalized Difference Vegetation Index (NDVI) in 100 ...
Particle size analysis of iron hydroxide adipate tartrate (IHAT) in a food supplement: Interlaboratory testing of a dynamic light scattering method
results demonstrate that dynamic light scattering can reliably measure the particle size of particles in the low nanometre range if samples are prepared and measured following a robust, easy-to-reproduce, ...
Neethling Strain-Based Homologous Live Attenuated LSDV Vaccines Provide Protection Against Infection with a Clade 2.5 Recombinant LSDV Strain.
BACKGROUND: Vaccination is the main control measure to prevent Lumpy skin disease (LSD), and Neethling-based homologous vaccines have been shown to be safe and effective against infection with classical clade ...
The importance of including a mental health dimension in a multimorbidity indicator: an analysis of Belgian health survey data.
disorders ought to be considered as well. This paper aims to measure the added value of including a mental health dimension in a population-based multimorbidity indicator and identify which mental health ...
Physicochemical characterization and genotoxicity assessment of nanomaterials using new approach methodologies
additive [3]. A detailed physicochemical characterization of the test materials is an essential first step in the risk assessment. It includes measuring the particle size distribution, surface charge, ...
Safety assessment of the substance 2,2'-oxydiethylamine for use in plastic food contact materials.
pro-rata. Migrating oligomers were identified and semi-quantified in 10% ethanol, 3% acetic acid and olive oil. Considering the measured migration and the virtual presence at the LOQ of the oligomers below ...
Susceptibility of Mammals to Highly Pathogenic Avian Influenza: A Qualitative Risk Assessment From the Belgian Perspective.
based on the field and experimental data are therefore necessary to implement and adapt risk-based mitigation measures. This will require continuous monitoring of avian influenza viruses in both birds and ...
Protective efficacy of classical vaccines and vaccination protocols against an exotic Newcastle disease virus genotype VII.2 in Belgian layer and broiler chickens.
this velogenic APMV-1 VII.2 strain. For fully field-vaccinated 26-week-old layer chickens, high levels of specific antibodies were measured at the time of the velogenic APMV-1 challenge, resulting in ...
