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. ...
Molecular surveillance of anti-malarial drug resistance in Democratic Republic of Congo: high variability of chloroquinoresistance and lack of amodiaquinoresistance.
the presence of the SVMNT haplotype. METHODS: In 2017, ten geographical sites across the DRC were selected. Dried blood samples were collected from patients attending health centres. Malaria was first ...
Risk assessment of chlorinated paraffins in feed and food
as the target organ. The Panel selected as reference points a BMDL10 of 2.3 mg/kg bw per day for increased incidence of nephritis in male rats, and of 36 mg/kg bw per day for increased relative kidney ...
DETERMINATION OF SENSITIZING AND IRRITATING LEACHABLES IN MENSTRUAL HYGIENE PRODUCTS
included as internal standard. Validation of the UPLC- TQMS method addressed selectivity, linearity, precision, trueness and accuracy. Out of the 15 investigated MHP s, 6 were found to leak 5 sensitizing and ...
Risk assessment of aflatoxins in food
exposure. Aflatoxins are genotoxic and AFB1 can cause hepatocellular carcinomas (HCC s) in humans. The CONTAM Panel selected a benchmark dose lower confidence limit (BMDL) for a benchmark response of 10% of ...
Weight and head circumference at birth in function of placental paraben load in Belgium: an ENVIRONAGE birth cohort study
including MeP, EtP and PrP) was negatively associated with birth weight in newborn girls (− 166 g, 95% CI: − 322, − 8.6, p = 0.04) after adjustment for a priori selected covariates. The sum of parabens was ...
Impact of DNA extraction on whole genome sequencing analysis for characterization and relatedness of Shiga toxin-producing Escherichia coli isolates
multilocus sequence typing and single nucleotide polymorphism analysis). Shiga toxin-producing Escherichia coli (STEC) was selected as a case study. Overall, data quality and inferred phylogenetic ...
Combining short and long read sequencing to characterize antimicrobial resistance genes on plasmids applied to an unauthorized genetically modified Bacillus
(GM) Bacillus subtilis isolated as unexpected contamination in a feed additive, and therefore considered unauthorized (RASFF 2014.1249), as a case study. In GM organisms, AMR genes are used as selection markers. ...
Selection of a Noninvasive Source of Human DNA Envisaging Genotyping Assays in Epidemiological Studies: Urine or Saliva?
genetic variation within the population. The aim of this study was to evaluate the characteristics and genotyping results of DNA extracted from 2 human DNA sources, selected for their rapid and noninvasive ...
A new multiplex RT-qPCR method for the simultaneous detection and discrimination of Zika and chikungunya viruses
and chikungunya (CHIKV) viruses simultaneously. Methods Two methods targeting different genome segments were selected from the literature for each virus. These were adapted for high genome coverage and ...
