Assessing the endocrine activity of PAHs using the DRE-, ERE- and PPARγ CALUX bioassays
was to determine the endocrine activity of 9 PAH s using three different CALUX bioassays: DRE- CALUX, ERE- CALUX and PPAR γ CALUX. Materials and methods Three CALUX (chemically activated luciferase gene ...
Physicochemical characterisation of several types of the E171 food additive
https://www.sciensano.be/nl/biblio/physicochemical-characterisation-several-types-e171-food-additive
test materials. The phase of the E171 particles was determined by powder electron diffraction. Several types of TiO2 particles were found in pristine E171. These types were shown to be applied as well in ...
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
stem bark extracts (ELBE) may counteract the in vivo hepatotoxic effects of aflatoxins, contaminants in food and feed. An HPLC- DAD method was developed and validated to determine the level of flavonoid ...

Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.
sample, the uncertainty related to sample preparation increased to 6.8%. The expanded measurement uncertainty related to the concentration determination was 25-45% in these complex samples, without a clear ...
A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.
study was set up to determine the size of environmentally relevant FeOx colloids with new methods, i.e. Flow Field Flow Fractionation (FlFFF- UV- ICP- MS) and single-particle ICP- MS / MS (sp- ICP- MS) ...

Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry
chromatography – tandem mass spectrometry (UHPLC- MS / MS) method for the simultaneous determination of four parabens (methyl-, ethyl-, propyl-, and butyl-paraben (MeP, EtP, PrP, BuP), four bisphenols (BP) (BPA, ...
Validation of a Bioinformatics Workflow for Routine Analysis of Whole-Genome Sequencing Data and Related Challenges for Pathogen Typing in a European National Reference Center: as a Proof-of-Concept.
employed typing schemas (including, among others, core genome multilocus sequence typing), and serogroup determination. We analyzed a core validation dataset of 67 well-characterized samples typed by means ...
