Analysis of mineral oil in food: results of a Belgian market survey
chromatograms with the same range of volatility. Since these two fractions have a different toxicological relevance, it is important to quantify them separately. Occurrence data on mineral oil are available only ...
Current levels of gonorrhoea screening in MSM in Belgium may have little effect on prevalence: a modelling study.
resistance. We develop a mathematical model to estimate the effectiveness of screening on prevalence. Separable Temporal Exponential family Random Graph Models are used to model the sexual relationships ...
Analysis of illegal peptide drugs via HILIC-DAD-MS.
been developed to detect and quantify these peptides. The emerging of more polar peptides however requires the introduction of other separation techniques. Therefore, we set out to develop and validate ...
Disability weights for infectious diseases in four European countries: comparison between countries and across respondent characteristics.
Methods: We analyzed paired comparison responses of the European DW study by participants’ characteristics with separate probit regression models. To evaluate the effect of participants’ characteristics, we ...
Chemometrics and chromatographic fingerprints to classify plant food supplements according to the content of regulated plants.
objective way. Two approaches were followed: (1) a multiclass model, (2) 2-class model for each of the targeted plants separately. For both approaches good classification models were obtained, especially when ...
Detection of regulated herbs and plants in plant food supplements and traditional medicines using infrared spectroscopy.
a series of self-made triturations of the targeted plants. After pretreatment of the spectral data chemometric classification techniques were applied to both data sets (IR and NIR) separately and the ...
Dietary exposure to pyrrolizidine alkaloids in young children and adults from the Belgian population (PASFOOD)
methods was required to detect the presence of PA s at ppb or even ppt levels. Analytical methods based on analytes extraction and SPE purification, followed by UPLC separation and MS / MS detection were ...
Invasion by the Alien Tree Alters Ecosystem Functions in a Temperate Deciduous Forest
general linear models to separate effects of invasion byon heterotrophic soil and litter respiration rates and on canopy foliar nutrient content from effects of soil chemical properties, litter quantity, ...
Foot-and-mouth disease virus serotype SAT1 in cattle, Nigeria.
FMDV SAT1 in West Africa. The VP1 coding sequence of the Nigerian 2015 SAT1 isolates diverges from reported SAT1 topotypes resulting in a separate topotype. The reporting of a novel FMDV SAT1 strain in ...
Diagnostic accuracy of p16(INK4a) immunohistochemistry in oropharyngeal squamous cell carcinomas: A systematic review and meta-analysis.
IHC or HPV DNA PCR alone but significantly more specific than either separate test. In conclusion, p16(INK4 a) IHC is highly sensitive but moderately specific to diagnose HPV-transformed OPSCC when used ...
