Organisation of Multi-Mycotoxin Proficiency Tests: Evaluation of the Performances of the Laboratories Using the Triple A Rating Approach
prepared in house. The homogeneity and the stability of these materials were verified according to the criteria laid down in ISO 13528 using randomly selected samples. Most of the targeted toxins were found ...
Selection and use of reference panels: a case study highlighting current gaps in the materials available for foot and mouth disease
post-vaccination serology, and address inter-laboratory differences in serological assays used to measure virus-specific FMD antibody responses. Since there are often limited resources to prepare and distribute ...
Influence of reduced levels or suppression of sodium nitrite on the outgrowth and toxinogenesis of psychrotrophic Clostridium botulinum Group II type B in cooked ham.
Chloride Sodium Nitrite Vacuum Abstract: Outgrowth and toxinogenesis of Clostridium botulinum Group II (non-proteolytic) type B were studied in cooked ham prepared with different NaNO (ranging from 0 to ...
Bepaling van spoorelementen in diverse matrices met spectrometische technieken.
preparations were mineralized with HNO3 in microwave oven and the concentrations of As, Cd, Ni, Pb in the samples were analyzed with an ICP- MS. Hg in these samples was determined with the AMA. 2.textile samples ...
Agglomeration of titanium dioxide nanoparticles increases toxicological responses in vitro and in vivo
influence of NP agglomeration on their toxicity/biological responses in vitro and in vivo. Results: We tested two TiO2 NP s with different primary sizes (17 and 117 nm) and prepared ad-hoc suspensions ...

Processes for Nanoparticles surveys this fast growing field, including established methods for the physical and chemical characterization of nanoparticles. The book focuses on sample preparation issues ...
Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.
spectrometry (spICP- MS). The evaluation of selected sample preparation protocols allowed identifying and optimizing the critical factors that determine the measurement of the particle size distribution by TEM. ...
Biological monitoring of exposure to pesticide residues among Belgian florists
during preparing bouquets and handling contaminated flowers. A study was conducted among volunteer Belgian florists in order to assess their total exposure by measuring concentrations of pesticides (parent ...
The occurrence of putative cognitive enhancing research peptides in seized pharmaceutical preparations: An incentive for controlling agencies to prepare for future encounters of the kind.
of 2017 and 2018 two different unknown suspicious preparations were encountered and were subjected to a plethora of different analyses in order to identify, if present, any bioactive compound. It ...
Impact of DNA extraction on whole genome sequencing analysis for characterization and relatedness of Shiga toxin-producing Escherichia coli isolates
study evaluated eight commercial DNA preparation kits for their potential influence on: (i) DNA quality for Nextera XT library preparation; (ii) MiSeq sequencing (data quality, read mapping against ...
