Human urine contamination with environmental pollutants: simultaneous determination using UPLC-MS/MS
parabens were found in 95 urine samples. The obtained results indicate that MP, EP, and PP were detected in 57%, 46%, and 40% of all samples, respectively. Urinary concentration for the three parabens was in ...
A simple dilute-and-shoot method for screening and simultaneous quantification of nicotine and alkaloid impurities in electronic cigarette refills (e-liquids) by UHPLC-DAD
a slightly different outcome between the newly developed UV-detection method and the targeted MS approach was found, due to the sensitivity of the different detection techniques. However, in the context of ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
limits of detection and quantification are in the range of 0.1-0.3 ng g−1 and 0.2-0.7 ng g−1, respectively. The applicability of the method was demonstrated on 71 human placenta samples from a Belgian ...
Might Oral Human Papillomavirus (HPV) Infection in Healthy Individuals Explain Differences in HPV-Attributable Fractions in Oropharyngeal Cancer? A Systematic Review and Meta-analysis.
collection, HPV detection, and population type was extracted. Prevalences were pooled using random-effects models for meta-analyses of binomial data. Correlations were assessed by the Spearman test. RESULTS: ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market.
emergence of superbugs. Therefore, simple and accurate analytical methods are necessary, which are capable to detect and quantify a wide range of antimicrobials in suspected illegal products. In this work, ...
Strong increase of true and false positive mycobacterial cultures sent to the National Reference Centre in Belgium, 2007 to 2016.
observational study investigated the numbers of analyses at the NRC and false positive cultures (interpreted as containing mycobacteria at referring clinical laboratories, but with no mycobacterial DNA detected ...
Meta-analysis of the accuracy of p16 or p16/Ki-67 immunocytochemistry versus HPV testing for the detection of CIN2+/CIN3+ in triage of women with minor abnormal cytology.
Atypical Squamous Cells of the Cervix Cyclin-Dependent Kinase Inhibitor p16 Cytodiagnosis Early Detection of Cancer Female Humans immunohistochemistry Ki-67 Antigen Papillomaviridae Papillomavirus Infections ...
Co-circulation of influenza A(H1N1)pdm09 and influenza A(H3N2) viruses, World Health Organization (WHO) European Region, October 2018 to February 2019.
viruses circulated widely and detection levels in primary care and hospital settings were similar to past seasons. Hospitalisation data may suggest an increased susceptibility to A(H1N1)pdm09 virus in older ...
Monitoring of pyrrolizidine alkaloids in beehive products and derivatives on the Belgian market
detection were developed with a focus on very low LOQ s and validated for the analysis of 16 PA s and 14 PANO s in honey, honey based candies and snacks as well as beehive products based food supplements. ...
Personal exposure to traffic-related air pollutants and relationships with respiratory symptoms and oxidative stress: A pilot cross-sectional study among urban green space workers.
roads with high traffic intensity. Concentrations of PAH s and benzene biomarkers did not systematically exceed the limits of detection. Among smokers, respiratory inflammation increased linearly with ...
