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 ...
Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements
× time points) were used for selection of orthogonal wavelengths by conducting a correlation analysis. After preparation of triturations, recording of the fingerprints and creation of datasets (corrected ...
The 3Rs Principle in the field of toxicology
Publication Type: Scientific poster, presentation or proceeding Authors: Mertens, Birgit; Mieke Van Mulders Source: COST Workshop “Animal models for lead selection against vector borne parasitic ...
Regulatory expectations on the use of vaccine reference standards for maintaining product quality.
and product qualification. Challenges – Manufactures are sometimes faced with the challenge to select, produce and qualify suitable standards for their intended use. Ideally, international ...
THE ANALYSIS OF ILLICIT DRUGS COLLECTED DURING A SUMMER FESTIVAL AND EVALUATION OF THE NARCOREADER FOR ON-SITE ANALYSIS OF MDMA
spectroscopic methods with as a downside the lack of accuracy and selectivity. The law still requires confirmation of these results with chromatographic methods. These conventional methods are precise but ...
COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
method was developed using ultra-high performance liquid chromatography with diode array detector (DAD). Furthermore, selection of orthogonal wavelengths was made to extract maximum information from the ...
Spectroscopic approaches for conformity analysis of e-liquids
taurine, vitamin E and CBD in e-liquids. Therefore a set of 236 e-liquids was selected. Since samples with caffeine, taurine, CBD and vitamin E as additives were hard to find, some of the samples were split ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
therefore a selection marker is often used to detect the bacteria who have included the modification in their genome. Antimicrobial resistance genes are often used as one of these markers. The construct may ...
Estimates of people who injected drugs within the last 12 months in Belgium- presentation
number of PWID in Belgium through a multiplier method using two existing treatment registers. After matching the three data sources, we identified 269 unique adult PWID in Brussels. Based on the selected ...
Advances in the physicochemical characterization of nanoparticles in a regulatory context.
a number-basis, electron microscopic measurement of (nano)particles is necessary in a regulatory context. Approaches, selected examples and new developments of transmission electron microscopic characterization are ...
