Use of Whole Genome Sequencing Data for a First in Silico Specificity Evaluation of the RT-qPCR Assays Used for SARS-CoV-2 Detection.
started in December 2019. COVID-19 cases are confirmed by the detection of SARS-CoV-2 RNA in biological samples by RT-qPCR. However, limited numbers of SARS-CoV-2 genomes were available when the first ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
agglomeration state. The measurement of the median value of the minimal external particle diameter distribution was intra-laboratory validated. The validation study included an assessment of the limit of ...
Nanomaterials for food applications: Analytical challenges and practical solutions for enforcing labeling of nanoingredients in food products in the European Union
limitations of existing analytical techniques, and the lack of validated studies and reference materials. This book chapter summarizes these challenges and, in addition, suggests a screening strategy for ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
limits of detection and quantification are in the range of 0.1-0.3 ng g−1 and 0.2-0.7 ng g−1, respectively. The applicability of the method was demonstrated on 71 human placenta samples from a Belgian ...
Genome Editing in Agriculture: Methods, Applications, and Governance—A paper in the series on The Need for Agricultural Innovation to Sustainably Feed the World by 2050
limitations of the approach. The paper also presents an overview of the current landscape of governance of genome editing, including existing regulations, international agreements, and standards and codes of ...
Slurry photocatalytic membrane reactor technology for removal of pharmaceutical compounds from wastewater: Towards cytostatic drug elimination
than the ones observed with slurry PMR s. Therefore the reasons why slurry PMR s may be considered as the next generation technology will be discussed in this work together with the limitations related ...
Scientific opinion on Malachite green in food
95% confidence limit for a benchmark response of 10% extra risk (BMDL10) of 13 mg/kg bw per day for hepatocellular adenomas and carcinomas was selected as reference point for neoplastic effects. For ...
Scientific Statement on Presence of microplastics and nanoplastics in food, with particular focus on seafood
nanoplastics as contaminants in food. Methods are available for identification and quantification of microplastics in food, including seafood. Occurrence data are limited. In contrast to microplastics no methods ...
A molecular approach for the rapid, selective and sensitive detection of Exophiala jeanselmei in environmental samples: development and performance assessment of a real-time PCR assay
selectivity (100 %), PCR efficiency (95.5 %), dynamic range and repeatability of this qPCR assay were subsequently evaluated. The limit of detection for this qPCR assay was determined to be 1 copy of genomic ...
Selenium content of Belgian cultivated soils and its uptake by field crops and vegetables.
accumulation is still limited at low soil Se concentrations. In loamy soils, weak correlations were found between the soil Se concentration and its concentration in wheat and potato. The uptake of Se increased ...
