detection in the range of 0.03–0.21 μg kg−1, and limit of quantification in the range of 0.09–0.48 μg kg−1), and precision (relative standard deviation (RSD) ≤ 12.9%), the analytical method was successfully ...

Towards the use of ion mobility mass spectrometry derived collision cross section as a screening approach for unambiguous identification of targeted pesticides in food

Conclusions The screening approach proposed in this study is unconventional and based on large mass accuracy (20 ppm) and retention time windows (0.5 min) to capture, in a first step, a maximum of detected ...

Relation between broiler and human Campylobacter jejuni strains isolated in Belgium from 2011 to 2013.

evaluation of the relation was based on the characteristics determined using multilocus sequence typing (MLST) alone and combined with flagellin gene A restriction fragment length polymorphism (flaA- RFLP) ...

Detecting cervical precancer and reaching underscreened women by using HPV testing on self samples: updated meta-analyses.

participation trials were included. hrHPV assays based on polymerase chain reaction were as sensitive on self samples as on clinician samples to detect CIN2 + or CIN3 + (pooled ratio 0.99, 95% confidence interval ...
