Evaluation of the shucking of certain species of scallops contaminated with domoic acid with a view to the production of edible parts meeting the safety requirements foreseen in the Union legislation
regulatory limit of 20 mg DA /kg with 99% certainty. Such an analysis was not possible for the other scallop species. In the absence of data from member states, published data of variations between scallops ...
Association between local airborne tree pollen composition and surrounding land cover across different spatial scales in Northern Belgium
composition patterns. The overall objective of this study is to determine local variations in tree pollen composition with passive samplers and to identify the surrounding landscape characteristics that drive them. In ...
Validation strategy of a bioinformatics whole genome sequencing workflow for Shiga toxin-producing Escherichia coli using a reference collection extensively characterized with conventional methods
bacterial pathogenic isolates at single nucleotide resolution, making it the ultimate tool for routine surveillance and outbreak investigation. The lack of standardization, and the variation regarding ...
Identifying nanodescriptors to predict the toxicity of nanomaterials: a case study on titanium dioxide
the development of alternative testing strategies such as computational (predictive) models based on in vitro testing. However, the variations in in vitro experimental conditions can influence the ...
New QSAR models to predict chromosome damaging potential based on the in vivo micronucleus test
were created using parameter variation and manual verification of (non-) alerting structures. To this extent, the original set of 718 compounds was split into a training (80 %) and a test (20 %) set. SAR ...
Bepaling van spoorelementen in diverse matrices met spectrometische technieken.
predetermined maximum limit. Pb in this sample also showed an increased concentration compared to the other samples. Since the variation between the replicas was high, a re-analysis of the sample will be ...
Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.
By combining optimized sample preparation with method validation, a significant variation in the particle size and shape distributions, the crystallographic structure (rutile versus anatase), and the ...
Alternating patterns of seasonal influenza activity in the WHO European Region following the 2009 pandemic, 2010-2018.
reporting entity and season (weeks 40-20) for 2010-2011 to 2017-2018. We explored geographical spread using correlation coefficients. RESULTS: There was variation in the regional influenza epidemics during ...
Selection of a Noninvasive Source of Human DNA Envisaging Genotyping Assays in Epidemiological Studies: Urine or Saliva?
genetic variation within the population. The aim of this study was to evaluate the characteristics and genotyping results of DNA extracted from 2 human DNA sources, selected for their rapid and noninvasive ...
Antibiotic consumption in Belgian acute care hospitals: analysis of the surveillance methodology, consumption evolution 2003 to 2016 and future perspectives.
antibiotic consumption in 2016 in 102 Belgian acute care hospitals was 577.1 DDD s/1,000 patient days and 3,890.3 DDD s/1,000 admissions with high variation between hospitals (interquartile ranges (IQR): ...
