Full Characterisation of Heroin Samples Using Infrared Spectroscopy and Multivariate Calibration

100.0, 75.0 and 95.5%, respectively. For regression, a root mean squared error of prediction (RMSEP) of 0.04 was obtained, pointing at good predictive properties. Furthermore, during mass spectrometric ...

Validation of a Targeted LC-MS/MS Method for Cereulide and Application in Food and Faeces.

and faeces, respectively. The linearity of the method was very good, with calculated R values above 0.995. The mean recovery of the method was within the acceptable range of 70.0%-120.0%, the ...

Attributing Ethiopian animal health losses to high-level causes using expert elicitation

class, and production system. Three-point questions were used to inform beta-pert distributions and capture uncertainty in estimates. Individual expert estimates were aggregated by quantile mean to produce ...

Coadministered pneumococcal conjugate vaccine decreases immune response to hepatitis A vaccine: a randomized controlled trial.

A antibody (anti- HAV) concentrations were measured before and 28 ± 3 days after vaccination. Adverse events (AE s) were recorded over 4 weeks. RESULTS: After vaccination, the anti- HAV geometric mean ...

Knowledge, perceptions and practices related to mosquitoes and mosquito-borne viruses: survey in Belgium, 2022

pictures of insects. Participants perceived the severity of MBV s as high (mean score 6.0/7.0), but their susceptibility to MBV s and mosquitoes lower (4.3/7.0). Participants were most motivated to take ...

Urine concentrations of Arsenic and its species in adolescents from Wallonia (Belgium).

had detectable concentrations of AsT. The geometric mean urine concentrations for adolescents were 8.1 μg/L for AsT, 2.7 μg/L for AB, and 3.7 μg/L for TRA. Since fish or seafood are a major arsenic ...

A proposal for further developing fatigue-related post COVID-19 health states for burden of disease studies

from the World Health Organization. In practice this means that milder cases, that may be occurring very frequently, are not included in estimates of the burden of long COVID which will result in ...

Development of novel analytical methods to trace small micro- and nanoplastics in food matrices

a diameter smaller 1 µm, called nanoplastics (NP s) that could be found in food matrices and environmental samples, by means of specific measurement techniques. Therefore, the aim of this work is to develop ...

Dietary exposure of Sorbates (E 200 – 202) and Benzoates (E 210 – 213) for the Belgian population

and frequencies. Mean exposure estimates ranged from 8 to 19% of the Allowed Daily Intakes (ADI s) (i.e. 11 and 5 mg/kg bw per day for SA and BA, respectively), and 95th percentile exposures ranged from ...

The Belgian physiotherapy reimbursement criteria for fall prevention fails in screening appropriately fall-prone community-dwelling older adults

adults (mean age 76 years ±7.4, 35% male). Thirty-nine participants experienced at least one fall in the 8 month follow up. Lusardi’s approach has a higher sensitivity score (89.7% compared to 10.3%) and ...
