this phenomenon. Prior to this, the use of the e-cigarette was not yet mainstream, as only nicotine-free e-cigarettes were allowed on the market. However, as a result of the legislative changes, ...
A Practical Method to Implement Strain-Level Metagenomics-Based Foodborne Outbreak Investigation and Source Tracking in Routine.
in the food vehicle without its prior isolation and link it back to human cases. We tested and validated a shotgun metagenomics approach by spiking food pathogens in specific food matrices using the ...
Food Chemistry, Function and AnalysisDNA Techniques to Verify Food Authenticity CHAPTER 8. GMO Detection and Identification Using Next-generation Sequencing
approaches can be applied. The whole-genome sequencing approach, on the one hand, requires no prior knowledge, and is suitable for the characterization of samples containing an isolated single GMO. The ...
DETERMINATION OF SENSITIZING AND IRRITATING LEACHABLES IN MENSTRUAL HYGIENE PRODUCTS
include the risk for priorly sensitized consumers, neither does it cover the risk for individuals susceptible to irritant contact dermatitis. Consequently, the overall risk for this group of consumers is ...
In vitro 50 Hz magnetic field long-term exposure: Cytogenetic tests on human lymphoblastoid TK6 cells and validation of the test environment
ELF- MF s on TK6 cells ensure the reproducibility of test results. Validation of exposure environment and exposure system are needed prior to performing tests with ELF- MF s. A simple, but effective ...
In vitro antigenotoxic activity, in silico ADME prediction and protective effects against aflatoxin B1 induced hepatotoxicity in rats of an Erythrina latissima stem bark extract
prior to AFB1 exposure (1 mg/kg). The ELBE group showed a decreased activity of ALP and γ- GT compared to the AFB1 group. Histopathological examination of the liver demonstrated ameliorative effects of ...
Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.
However, no validations have yet been performed with food additives or real samples containing food additives requiring a sample preparation step prior to analysis. A single-particle inductively coupled ...

liquids (e-liquids) available on the Belgian market through analysis of their chemical composition. Methods: By using in-house validated methods, a total of 246 e-liquids purchased prior (2013-2015), ...
Strong increase of true and false positive mycobacterial cultures sent to the National Reference Centre in Belgium, 2007 to 2016.
(1,097/2,534) of all samples in 2016.ConclusionWe recommend inclusion of NTM in sentinel programmes. The large increase of false positive cultures is hypothesised to result from processing issues prior to arrival ...
Clonal Spread of Candida glabrata Bloodstream Isolates and Fluconazole Resistance Affected by Prolonged Exposure: a 12-Year Single-Center Study in Belgium.
(10.7%) of the isolates. An analysis of the antifungal consumption data revealed that recent prior exposure to fluconazole increased the risk to be infected by a resistant strain. In particular, the ...
