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): ...
Thyroid cancer incidence near nuclear sites in Belgium: An ecological study at small geographical level
Belgium, variations in thyroid cancer incidence were observed around the major nuclear sites. The present ecological study investigates whether there is an excess incidence of thyroid cancer among people ...
Real-time prediction of influenza outbreaks in Belgium.
different epidemic seasons, providing weekly predictions makes it possible to capture variations in the ILI incidence. The confidence region becomes more representative of the epidemic behavior as ILI data ...
