COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
fingerprints by performing a correlation analysis on the DAD data. Chemometric analysis was carried out using two approaches: 1. binary models for each plant separately and 2. multiclass models. The data were ...
Multidimensional Chromatographic Fingerprinting Combined with Chemometrics for the Identification of Regulated Plants in Suspicious Plant Food Supplements.
the chromatogram, a multidimensional fingerprint (absorbance × wavelength × retention time) was considered. This was achieved by selecting several wavelengths through a correlation analysis. The data ...
Combined Phylogeographic Analyses and Epidemiologic Contact Tracing to Characterize Atypically Pathogenic Avian Influenza (H3N1) Epidemic, Belgium, 2019.
strongly correlated with the phylogeographic pattern of the epidemic. We detected only a limited association between wind direction and direction of viral lineage dispersal. Our results highlight the ...
Assessment of the impact of the Belgian and French food industry on obesity and population nutrition
commitments and practices, as well as the correlation between both, of major food companies in Belgium and France. The ‘Business Impact Assessment’ (BIA-Obesity) was applied to evaluate nutrition-related ...
Sex difference in innate inflammatory response and macrophage polarization in Streptococcus agalactiae-induced pneumonia and potential role of microRNA-223-3p.
higher M1 / M2 ratio following GBS infection. Notably, compared to male mice, we detected higher amount of miR-223-3p in macrophages from females that correlated negatively with M1 phenotype. These results ...
Noninvasive integrative approach applied to children in the context of recent air pollution exposure demonstrates association between fractional exhaled nitric oxide (FeNO) and urinary CC16.
investigating their mutual correlation in children exposed to PM. Samples from a small-scale study conducted in 42 children from urban (n = 19) and rural (n = 23) schools examined at two time points, were ...
Multidimensional Fingerprint Development for the Detection of Tribulus terrestris in Plant Food Supplements
American Herbal Pharmacopoeia) was developed using ultra high performance liquid chromatography coupled with a diode array detector. Next, a correlation analysis comparing the wavelengths was performed and ...
SARS-CoV-2 Surveillance in Belgian Wastewaters
Correlation public health authority SARS-CoV-2 Surveillance viral load per capita viral to faecal ratio wastewater-based epidemiology Abstract: Wastewater-based surveillance was conducted by the national public ...
Validity of air pollution annoyance to assess long-term exposure to air pollution in Belgium
and annual means of air pollution concentration at the residence. Self-reported air pollution annoyance was assessed through a five-point Likert scale. Statistical analyses included Spearman correlation ...
Benchmarking the nutrition-related commitments and practices of major Belgian food companies.
was calculated. Correlations between commitments and performance indicators were calculated applying the Spearman’s rank correlation coefficient. RESULTS: Eighteen out of 31 companies participated ...
