Establishing disease models for the Belgian national burden of disease study: challenges and perspectives
contains all cases. This parent node then gives rise to multiple “child nodes”, with the terminal child nodes representing the individual health states. In BeBOD, disease models and severity distributions ...
Optimised dispersion protocol for particle size measurement of copper oxides applied as feed additives and plant protection products
commercially distributed as powders, and limited information on their particle size distribution is available. The EFSA Guidance on Particle-Technical Requirements requires measuring the particle size ...
Surveillance épidémiologique de la rougeole (Morbillivirus)- 2024
enfants de moins d’un an, qui sont encore trop jeunes pour être vaccinés. La distribution par group d’âge différait entre les régions. Sur l’ensemble des cas, la moitié n’était pas vaccinée (286/526) et ...
Implementation of METROFOOD services in the Belgium node
Forum on Research Infrastructures) research infrastructure (RI), METROFOOD- RI, an European distributed- RI aimed at promoting scientific excellence via high-level metrological services in food and ...
Assessing particle count in electron microscopy measurements of nanomaterials to support regulatory guidance
minimum particle count generally depends on the width of the size and shapedistributions and that the median of the distribution can be determined with the highest precisioncompared to other percentiles. ...
Particle size analysis of iron hydroxide adipate tartrate (IHAT) in a food supplement: Interlaboratory testing of a dynamic light scattering method
constituent particle size, referred to in the implementing regulation as ‘primary particle size’. In this study, a method to determine the constituent particle size distribution of IHAT using the volume-based ...
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, ...
Associations of heat with diseases and specific symptoms in Flanders, Belgium: An 8-year retrospective study of general practitioner registration data.
Flanders, Belgium. METHODS: We used eight years (2012-2019) of aggregated data of daily GP visits during the Belgian summer period (May-September). A distributed lag nonlinear model (DLNM) with time-stratified ...
Replication Characteristics of African Swine Fever Virus (ASFV) Genotype I E70 and ASFV Genotype II Belgium 2018/1 in Perivenous Macrophages Using Established Vein Explant Model.
strain-dependent vascular pathology, leading to hemorrhagic fever, is an important pathogen in swine. The pathogenesis of ASFV is determined by the array and spatial distribution of susceptible cells within the ...
Reflections of the NRL: implementation of EN ISO 11133 in food microbiology laboratories
2 (published in 2020) describes the performance testing of confirmation media and reagents. EN ISO 11133:2014 applies to producers such as commercial bodies producing and/or distributing ready-to-use or ...
