Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.

However, no validations have yet been performed with food additives or real samples containing food additives requiring a sample preparation step prior to analysis. A single-particle inductively coupled ...

Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry

bisphenols (BP) (BPA, BPB, BPF, and BPS) and two alkylphenols (nonyl phenol (NP) and tert-octylphenol (OP) in human placenta samples. After a short sample preparation time the extracts are analysed by UHPLC- ...

High abundance and diversity of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in faeces and tonsils of pigs at slaughter.

Tryptone Bile X-glucuronide agar supplemented with 1mg/L cefotaxime) were detected in 72 faecal samples (75%; 95% CI: 64-83%) and 45 tonsil samples (47%; 95% CI: 35-59%), in numbers up to 5.5 and 5.6log10 ...

Development and performance assessment of a luminex xMAP® direct hybridization assay for the detection and identification of indoor air fungal contamination.

using classical protocols based on culturing. However, this culture dependency could influence the representativeness of the fungal population detected in an analyzed sample as this includes the dead and ...

Model-Based Classification for Digital PCR: Your Umbrella for Rain.

conditional on its observed fluorescence and the distributional shape in no-template control samples. This methodology acknowledges the inherent uncertainty of the classification and provides a natural measure ...

Discrimination of three genetically close Aspergillus species by using high resolution melting analysis applied to indoor air as case study.

sydowii, and 0.1 pg of gDNA for A. versicolor. The HRM analysis was also successfully tested on environmental samples. CONCLUSION: We reported the development of HRM tools for the discrimination of A. ...

Neonatal thyroid-stimulating hormone concentration and psychomotor development at preschool age.

screened in 2008, 2009 and 2010 by the Brussels newborn screening centre. The sampling was stratified by gender and TSH range (0.45-15 mIU/L). Infants with congenital hypothyroidism (>15 mIU/L), low birth ...

Nicotine Dependence and Urinary Nicotine, Cotinine and Hydroxycotinine Levels in Daily Smokers.

cigarettes per day among biomarker concentrations and individual FTND  items. METHODS: Urine samples and questionnaire data of 239 daily smokers were obtained. Nicotine, cotinine and hydroxycotinine urinary ...

Development of a Luminex xTAG® assay for cost-effective multiplex detection of β-lactamases in Gram-negative bacteria.

coli strains encoding both blaTEM-1 and blaTEM-52 genes. The turn-around time from single colony to result is 5 h and total consumable costs remained <€5 per sample. CONCLUSIONS: We designed and ...
