Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety

chosen for further studies (i.e. 24 hours enrichment as stated in the current international standard procedure, classical commercial DNA extraction and no amplification). Cheese samples were spiked with ...

Report on an initial assessment of long-read sequencing for metagenome (community and AMR) analysis (defined community, spiked and real simple and complex matrices) and comparison to current short-read standard

Residential Exposure to Urban Trees and Medication Sales for Mood Disorders and Cardiovascular Disease in Brussels, Belgium: An Ecological Study

2012. Trait data were subsequently extracted for 309,757 trees in 604 census tracts. We used the average annual age-standardized rate of medication sales in Brussels for the period 2006 to 2014, ...

4DEMON: Integrating 40 Years of Data on PCB and Metal Contamination in Marine Sediments of the Belgian Part of the North Sea

highly standardized trend modeling approaches like those proposed by regional sea conventions such as OSPAR, named after the Oslo and Paris conventions.Therefore, we applied alternative approaches, ...

Ecotoxicity profile of heavily contaminated surface water of two rivers in Tunisia

approaches. In the physicochemical analysis, the recorded levels of COD and TSS in both samples exceed the Tunisian standards. Using the analytical approach, several metals and some textile dyes were detected. ...

Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials

material Abstract: An approach for the size measurement of particulate (nano)materials by transmission electron microscopy was evaluated. The approach combines standard operating procedures for specimen ...

Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry

negative electrospray ionization.  Labeled internal standards and matrix-matched calibration are used for quantification of the compounds. The method was validated according FDA guideline for bio analytical ...

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 ...

Spatial and temporal variations in airborne pollen in Europe.

analysed. The mean and standard deviation (SD) were calculated regardless of the number of years included in the study period, while trends are based on those time series with 8 or more years of data. Trends ...
