Parasite distribution and associated immune response during the acute phase of Toxoplasma gondii infection in sheep.
the detection limit three weeks after infection. This coincides with an increase in parastic-specific serum IgG1 and IgG2 and a decrease of the antigen-specific IFN-gamma response in PP, PBMC and ...
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.
species-specific real-time quantitative (q) PCR assays, as DNA extracted from urine contains, besides human, microbial DNA also, which largely contributes to the total DNA yield. In addition, the kits giving a good ...
Validation of a sensitive DNA walking strategy to characterise unauthorised GMOs using model food matrices mimicking common rice products
with degraded DNA. Given its specificity, sensitivity, reliability, applicability and practicability, the proposed approach is a key detection tool, easily implementable in enforcement laboratories. ...
Seroprevalence of Toxoplasma gondii in domestic sheep in Belgium.
infection in sheep in Belgium and confirms the high prevalence of Toxoplasma-specific IgG antibodies in the sheep population. Health Topics: Food consumption and food safety Category: A1 FOS ...

A two-step lyssavirus real-time polymerase chain reaction using degenerate primers with superior sensitivity to the fluorescent antigen test.
with the remaining lyssavirus species. The diagnostic specificity was 100% and the sensitivity proved to be superior to that of the fluorescent antigen test. The limit of detection was ≤ 1 50% tissue ...
Multi-dye residue analysis of triarylmethane, xanthene, phenothiazine and phenoxazine dyes in fish tissues by ultra-performance liquid chromatography-tandem mass spectrometry.
Sensitivity and Specificity Tandem Mass Spectrometry Abstract: Beside the possible illegal use of malachite green in aquaculture, other familiar dyes could also been applied by fraudulent producers due to their ...
In vitro model to study the endocrine disrupting activity of migration products from plastic food contact materials
luciferase gene, as a reporter gene, and a DNA responsive element specific to the human oestrogen receptor. The biological activity of a chemical compound is monitored by the measurement of light emitted by ...
