Assessment of the clinical and analytical performance of the Aptima SARS-CoV-2 assay using the VALCOR protocol.
a standard comparator assay. Diagnostic test parameters such as sensitivity, specificity and overall per cent agreement were calculated for the clinical performance of Aptima SARS-CoV-2 assay. RESULTS: A total ...
Regulatory safety assessment of nanoparticles for the food chain in Europe
that may retain properties at the nanoscale. Key parameters and threshold values for establishing the presence of small particles, the techniques and methods for characterisation in complex matrices, as ...
Microbiological safety of aged meat.
to a description of the different stages, data were collated on key parameters (time, temperature, pH and a) using a literature survey and questionnaires. The microbiological hazards that may be ...
Impact of experimental design factors on the potency of genotoxicants in in vitro test
different test conditions. We therefore investigated the influence of two parameters, i.e. cell type and exposure duration, on the potencies of two known genotoxicants [aflatoxin B1 and ethyl methanesulfonate ...
The GEONs API-fingerprint program: Tackling falsifications of APIs
quality of the product on some distinct parameters, often chosen based on the manufacturing process. A MSSFP study allows to obtain a global image of the sample, to compare to batches of the (presumed) ...
Development of a reliable UHPLC-MS/MS method for simultaneous determination of zearalenone and zearalenone-14-glucoside in various feed products
impurities and enriching the target analytes in different feeds. The critical parameters affecting the performance of the solid-phase extraction (SPE) procedure were carefully optimized, and 20% acetonitrile ...
Advances in the physicochemical characterization of nanoparticles in a regulatory context.
its resolution covering 1-100 nm, its possibility to identify constituent particles in aggregates and agglomerates and to measure key parameters such as their minimal external dimension on ...
Methodological considerations in injury burden of disease studies across Europe: a systematic literature review.
injury BoD studies undertaken across Europe and to comprehensively review the methodological design choices and assumption parameters that have been made to calculate years of life lost (YLL) and years ...
Estimating national and subnational nutrient intake distributions of global diets
have not been consistently disaggregated by sex and age groups, and their parameters and full distributions are often not publicly available. OBJECTIVES: We sought to derive usual intake distributions ...
Bottom-up approach to build a ‘precision’ risk factor classification for diabetic foot ulcer healing. Proof-of-concept
classification systems, were prospectively validated, not all individual parameters were shown to have consistent associations with healing. In this study, we used a bottom-up approach relying on robust methods to ...
