Assessment of estrogenic compounds in paperboard for dry food packaging with the ERE-CALUX bioassay
samples. Bis(2-ethylhexyl)phthalate (DEHP), dibutyl phthalate (DBP), butyl benzyl phthalate (BBP) and 1,2-cyclohexane dicarboxylic acid diisononyl ester (DINCH) were determined in all extraction and ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market.
Medicinal and Health Products (FAMHP), were analyzed using the two described methods. About half of them were not compliant and some samples that contained clavulanic acid showed a serious reduction in the ...
Isoniazid Bactericidal Activity Involves Electron Transport Chain Perturbation.
inhibition. The activity of isoniazid (INH), a key first-line bactericidal antituberculosis drug currently known to inhibit mycolic acid synthesis, becomes extremely poor under stress conditions, such as ...
Study of the underlying mechanisms and consequences of pathogenicity differences between two in vitro selected G1-H9N2 clones originating from a single isolate.
of the MDCK-clone on splenocytes was further demonstrated via ChIFN-γ lack production after ex vivo mitogenic stimulation. Genome sequencing of the two clones identified only four amino acid ...
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.
2-naphthol, S-phenylmercapturic acid) and questionnaires. Data on respiratory health and oxidative stress were collected using questionnaires and respiratory/urinary biomarkers (exhaled nitric oxide [NO], ...
Development of a QuEChERS-Based UHPLC-MS/MS Method for Simultaneous Determination of Six Alternaria Toxins in Grapes
determination of alternariol (AOH), altenuene (ALT), tentoxin (TEN), altenusin (ALS), tenuazonic acid (TeA), and alternariol monomethyl ether (AME) in grapes was developed by ultra-high-performance liquid ...
Profiling of the beneficial and potentially harmful components of Trichodesma indicum seed and seed oil obtained by ultrasound-assisted extraction
LC-Q- TOF- MS. Rosmarinic acid (67%) and isomers of salvianolic acid B/E/L (26%) were the main phenolics, while melitric acid A and sebestenoid C/D constituted 6% and 1%, respectively. Only a minor part ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market
and some samples that contained clavulanic acid showed a serious reduction in the amount of this molecule (in one sample only 14% of the claimed dosage was found). These quality issues might be ...
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
urinary biomarkers (1-hydroxypyrene, 1-naphthol, 2-naphthol, S-phenylmercapturic acid) and questionnaires. Data on respiratory health and oxidative stress were collected using questionnaires and ...
Risk to human health related to the presence of perfluorooctane sulfonic acid and perfluorooctanoic acid in food
PFOA PFOS Risk Assessment Abstract: Abstract The European Commission asked EFSA for a scientific evaluation on the risks to human health related to the presence of perfluorooctane sulfonic acid (PFOS) ...
