Victoria Pure Blue BO is a dye that bears some therapeutic activity and that can be retrieved in effluent or may be used in aquaculture as a prohibited drug. In this study, the metabolism and tissue distribution during uptake and depuration of VPBO were investigated in order to propose a residue marker of illegal treatment in fish. The dye was admi...
En s’appuyant sur des recherches étymologiques et philosophiques, l’auteur nous montre que parallèlement aux nombres ordinaux et cardinaux, il existe une troisième catégorie de nombres qu’il appelle les nombres structuraux. Ces nombres, qui étaient connus des civilisations romaine et grecque, ont un nom et une existence historique, qu’il nous appar...

The presence of antimicrobial residues in food-producing animals can lead to harmful effects on the consumer (e.g., allergies, antimicrobial resistance, toxicological effects) and cause issues in food transformation (i.e., cheese, yogurts production). Therefore, to control antimicrobial residues in food products of animal origin, screening methods ...

Colistin is a polypeptide antibiotic mainly used in porcine and poultry to treat gastrointestinal infections. It has been included by the World Health Organisation (WHO) in the list of critically important human antibiotics of high priority for antimicrobial resistance since 2017. Therefore, it is necessary to develop specific and sensitive screeni...
LC-MS/MS method was developed for the efficient identification and quantification of 21 banned substances including various nitroimidazoles, nitrofurans, pharmacologically-active dyes and chloramphenicol, respectively in aquaculture products. The sample preparation was started by acid-treatment with 2-nitrobenzaldehyde (NBA) to liberate matrix-boun...
Les associations de premelanges contenant des antibiotiques sont utiles et courantes, sans connaissance pleine et entiere de leurs effets. Depuis deux ans, en raison de l’obligation pour les fabricants d’aliments medicamenteux de declarer les cessions d’antibiotiques, mais aussi grace a une analyse des connaissances actuelles sur les interactions p...
Chemical (eg pesticides, veterinary drugs, etc.) and bacteriological contaminants (eg. foodborne pathogens) could contaminate animal and plant derived food products for human consumption. Some antibiotic residues (eg. chloramphenicol, nitrofuran metabolites, dyes) are banned in foodstuffs of animal origin (eg. milk, meat, eggs, etc.) in European Un...
Obsah tejto práce zahrňuje tri základné kapitoly, pojednávajúce jednako o popisu kvalitatívnych parametrov napájacieho napätia a jednako o meraní a vyhodnocovaní zistených dat. Teoretická časť tvorí úvodnú kapitolu, v ktorej sú popísané základne charakteristiky napájacieho napätia a pre ne normou dané limity. V ďalšej kapitole následuje popis príst...
