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. ...

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 ...

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 ...

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

(ZIKV) 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 ...

Detection strategy targeting a chloramphenicol resistance gene from genetically modified bacteria in food and feed products

resistance (AMR) genes as selection markers, are frequently used to produce food and feed enzymes, additives and flavourings. Such commercialized microbial fermentation products should not contain GMM, or ...

A new multiplex RT-qPCR method for the simultaneous detection and discrimination of Zika and chikungunya viruses.

were selected from literature for each virus, adapted for high genome coverage and joined into a four-plex assay which was thoroughly in-house validated. The SCREENED tool was used to evaluate the ...

Is the European Health Interview Survey online yet? Response and net sample composition of a web-based data collection.

organized using the EHIS wave 3 model questionnaire. The sample was selected according to a multistage, clustered sampling procedure with geographical stratification. Field substitution was applied; ...

Piacentinu Ennese PDO cheese as reservoir of promising probiotic bacteria.

in order to select promising probiotic strains to be further used in humans. One hundred and sixty-nine lactic acid bacteria (LAB) were isolated from 90 days ripened cheeses and identified by Rep- PCR ...

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

validation study included an assessment of the limit of detection, working range, selectivity, precision, trueness, robustness, and ruggedness. An uncertainty that was associated to intermediate precision in ...
