Evaluation of the migration of chemicals from baby bottles under standardised and duration testing conditions.

toxicity assessment, the most toxic migrating compounds were selected to be monitored and quantified using validated GC- and LC-QqQ- MS methods. The effect of several ‘real-life-use conditions’, such as ...

Generation and Characterization of Six Recombinant Botulinum Neurotoxins as Reference Material to Serve in an International Proficiency Test.

and validated amino acid analysis, respectively. In addition, BoNT/A₁, B₁, E₁ and F₁ were successfully detected by immunological assays, unambiguously identified by mass spectrometric-based methods, and ...

Development and performance assessment of a qualitative SYBR® green real-time PCR assay for the detection of Aspergillus versicolor in indoor air.

indoor airborne fungal contamination is a common tool to help understanding the link between fungi in houses and respiratory problems. Classical analytical monitoring methods, based on cultivation and ...

Guidelines for optimisation of a multiplex oligonucleotide ligation-PCR for characterisation of microbial pathogens in a microsphere suspension array.

targeted bacterial species, evaluation of the method of DNA isolation, the probe concentration, the amount of microspheres, and the concentration of reporter dye is advisable in the development of any MOL- ...

Fast and discriminative CoSYPS detection system of viable Salmonella spp. and Listeria spp. in carcass swab samples.

validation, the results of the complete workflow were compared, according to the ISO 16140:2003, with the ISO reference methods for detection, isolation and confirmation of Listeria monocytogenes and Salmonella ...

Genetic diversity of Shiga toxin-producing Escherichia coli O157 : H7 recovered from human and food sources.

significant concordance (P <0.05) between the LSPA-6 assay and the other typing methods. Multivariable regression analysis suggested that tir (255T) was the most distinctive genotype that can be used to ...

Acrylonitrile exposure in the general population following a major train accident in Belgium: a human biomonitoring study.

suspected exposure. METHODS: Between May 18-25, 242 residents participated in the study. N-2-cyanoethylvaline (CEV), a biomarker that is highly specific for ACN exposure, was measured in the blood. To account for ...

Comparative study of seven commercial kits for human DNA extraction from urine samples suitable for DNA biomarker-based public health studies.

biomarkers as a result of the simple and noninvasive collection method. These studies, involving many samples, require a rapid, easy, and standardized extraction protocol. Moreover, for practicability, there ...
