Development of a real-time PCR marker targeting a new unauthorized genetically modified microorganism producing protease identified by DNA walking

PCR marker was demonstrated by assays performed by an external laboratory. Health Topics:  Food consumption and food safety Consommation et sécurité alimentaires Voedselconsumptie en –veiligheid ...

Safety assessment of titanium dioxide (E171) as a food additive.

a minimum external dimension < 100 nm. In addition, the Panel noted that constituent particles < 30 nm amounted to less than 1% of particles by number. The Panel therefore considered that studies with ...

Safety assessment of titanium dioxide (E171) as a food additive

E 171 have a minimum external dimension < 100 nm. In addition, the Panel noted that constituent particles < 30 nm amounted to less than 1% of particles by number. The Panel therefore considered that ...

Identifying nanodescriptors to predict the toxicity of nanomaterials: a case study on titanium dioxide

experimental variations determine the outcome of modelling using three case studies. We used TiO2in vitro data from our previously published study as case study 1 and two other external case studies (case study ...

Development and validation of an ultra-high performance liquid chromatography-tandem mass spectrometry method to measure creatinine in human urine.

on bioanalytical method validation using Certified Reference samples from the German External Quality Assessment Scheme (G-Equas) proficiency test. All obtained results for accuracy and recovery are ...

The European COPHES/DEMOCOPHES project: towards transnational comparability and reliability of human biomonitoring results.

specially prepared from native, non-spiked, pooled urine samples and was tested for homogeneity and stability. Four external quality assessment exercises were carried out. Highly esteemed laboratories from ...

Characterization of the TiO2 E171 food additive

particles and small aggregates and agglomerates. Under the optimized conditions, the minimal external dimension of the primary particles could be measured more precisely and accurately by a combination of EM ...
