Microbial quality analysis of falsified medicines seized by controling agencies

chemical risks (e.g. lack of dosage accuracy, etc.) are highlighted in this study. Taken together, the obtained results indicate that at least 68% of the analyzed products harbored an unneglectable chemical ...

THE ANALYSIS OF ILLICIT DRUGS COLLECTED DURING A SUMMER FESTIVAL AND EVALUATION OF THE NARCOREADER FOR ON-SITE ANALYSIS OF MDMA

time-consuming and of high cost. There is a need for more rapid and still accurate analysis, with cost-effective and portable methods. Aim: As the first goal of this study, a selection of drug samples is analysed ...

Occurrence of microcystin congeners in surface waters and food in Belgium as a source of exposure to humans

environmental samples. This has a negative downstream effect on possible risk assessment studies that would establish the exposure and influence of the different cyanotoxins on public health, and on the final ...

Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety

contaminant present in the sample at once, possibly also at the SNP level. At the time this study started, shotgun metagenomics for the study of food contaminants was in its infancy. Moreover, strain-level ...

CHROMATOGRAPHIC FINGERPRINT DEVELOPMENT FOR THE DETECTION OF TRIBULUS TERRESTRIS IN PLANT FOOD SUPPLEMENTS

subject of this thesis, is a plant that is frequently present in sexual enhancing herbal food sup-plements sold to treat ED. Aim: The study developed a screening approach for TT using Ultra High Pressure ...

Development of a data-intensive centralized system for surveillance and outbreak investigation of bacterial pathogens using whole-genome sequencing

surveillance and outbreak investigation that combines both core-genome multilocus sequence typing and single nucleotide polymorphism-typing was developed. This method was used to study the spread of ...

Tick-borne diseases in Belgium: The incidence and economic burden of Lyme borreliosis and the occurrence of other tick-borne infections

have remained. This thesis aims to contribute to the assessment of the burden of LB in Belgium, amongst others, by setting up a prospective cohort study. This work resulted in estimations of the ...

Development of vibrational spectroscopic methods combined with chemometrics for the detection and quantification of nicotine in e-liquids.

improvement of Raman PLS model and further SERS studies with tests on a larger number of samples are still needed. Health Topics:  E-sigaret E-cigarette E-cigarette Service:  Médicaments et produits de santé ...

Chemical and toxciological characterization of e-liquid cigarettes

analytical methods used in these studies have not always been well validated and thus the results of these studies need to be critically examined; three main problems could be uncovered: (1) the content of ...

Bepaling van spoorelementen in diverse matrices met spectrometische technieken.

has shown that Ti nanoparticles are contained in the fibers. Conclusion Only low concentrations of trace elements were found in most of the food enzyme preparations studied. The information collected ...
