Strain-level characterization without culture enrichment? Easing and accelerating outbreak investigation using shotgun metagenomics facilitated with nanopore adaptive sampling
a proof-of-concept, we explored the use of adaptive sampling using various databases (depletion of the food matrix i.e. potato, enrichment of a selection of foodborne pathogens, enrichment of a database of ...
EFSA Project on the use of New Approach Methodologies (NAMs) for the hazard assessment of nanofibres. Lot 1, nanocellulose oral exposure: gastrointestinal digestion, nanofibres uptake and local effects
(iii) assessment of any digestion or degradation of NC by the human microbiome. Eight NC samples belonging to the three NC types, plus a comparator in the micro-range, were selected as study materials and ...
Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements

Time series modelling for wastewater-based epidemiology of COVID-19: A nationwide study in 40 wastewater treatment plants of Belgium, February 2021 to June 2022
metrics at different lag times were used to predict incident COVID-19 cases. Model selection was based on AIC c minimization. Results: In 3¾0 WWTP s, RNA levels were best explained by incident cases, flow ...
Data collection in pandemic times: the case of the Belgian COVID-19 health surveys
