Chemical and toxciological characterization of e-liquid cigarettes

methods were developed for the quantitative determination of nicotine and its related impurities (HPLC- DAD) and for the flavours diacetyl and acetylpropionyl (HS / GC- MS). Also, screening methods were ...

Use of Whole Genome Sequencing Data for a First in Silico Specificity Evaluation of the RT-qPCR Assays Used for SARS-CoV-2 Detection.

the bioinformatics tool SCREENED and a total of 4755 publicly available SARS-CoV-2 genomes, downloaded at two different time points, to evaluate the specificity of 12 RT-qPCR tests (consisting of ...

A new multiplex RT-qPCR method for the simultaneous detection and discrimination of Zika and chikungunya viruses

and combined in a four-plex assay that was thoroughly validated in-house. The SCREENED tool was used to evaluate the sequence coverage of the method. Results The full validation approach showed that the ...

Increased surface area of halloysite nanotubes due to surface modification predicts lung inflammation and acute phase response after pulmonary exposure in mice

not clear. We assessed the toxicological response to HNT s (NaturalNano (NN)) before and after surface etching (NN-etched). Potential cytotoxicity of the two HNT s was screened in vitro in MutaTMMouse ...

A new multiplex RT-qPCR method for the simultaneous detection and discrimination of Zika and chikungunya viruses.

were selected from literature for each virus, adapted for high genome coverage and joined into a four-plex assay which was thoroughly in-house validated. The SCREENED tool was used to evaluate the ...

Prevalence of pathogens in ticks collected from humans through citizen science in Belgium.

humans in 2017. METHODS: Using a citizen science approach based on an existing notification tool for tick bites, a sample of ticks was collected across the country. Collected ticks were screened by PCR for ...

Determinants of persistent organic pollutant (POP) concentrations in human breast milk of a cross-sectional sample of primiparous mothers in Belgium

were investigated using two-way contingency tables and multivariable generalized linear models. Results Fifteen of the 23 screened POP s were detected in the breast milk samples. Four organochlorine ...
