Spectroscopic approaches for conformity analysis of e-liquids
modelling. Next to baseline correction, classical preprocessing techniques like standard normal variate (SNV), derivatives and scaling were explored. In a first step, supervised modelling, using partial least ...
Praktijkrichtlijn voor het opzetten van een kwaliteitssysteem in de erkende laboratoria voor pathologische anatomie werkzaam binnen het kader van het Erkenningsbesluit
vereisten van het Erkenningsbesluit) en een ISO- accreditatie (door BELAC, volgens de norm NBN EN ISO 15189). Dit onderscheid is belangrijk voor een correcte benadering en interpretatie van deze ...

approche et une interprétation correctes de la Directive Pratique qui ne concerne que l’agrément des laboratoires et qui peut être utilisée pour satisfaire aux exigences de l’Arrêté d’agrément. La Directive ...
Deepening of In Silico Evaluation of SARS-CoV-2 Detection RT-qPCR Assays in the Context of New Variants
future SARS-CoV-2 testing. Given the potential threat of the new variants, it is crucial to assess if they can still be correctly targeted by the primers and probes of the RT-qPCR assays. Our study ...
Chemometrics and chromatographic fingerprints to classify plant food supplements according to the content of regulated plants.
identification of the correct plants, confirmed by mass spectrometry. Therefore chromatographic fingerprinting combined with chemometric modelling can be considered interesting to make a more objective decision on ...
Detection of regulated herbs and plants in plant food supplements and traditional medicines using infrared spectroscopy.
IR data, using SIMCA as modelling technique. During validation of the model, using an external test set, 21 of 25 were correctly classified and six of the nine targeted plants showed no ...
Prevalence of Age-Related Macular Degeneration in Europe: The Past and the Future.
early and late AMD was calculated using random-effects meta-analysis stratified for age, birth cohort, gender, geographic region, and time period of the study. Best-corrected visual acuity (BCVA) was ...
Zona pellucida gene mRNA expression in human oocytes is related to oocyte maturity, zona inner layer retardance and fertilization competence.
Presence of ZP3 protein in CC and oocytes was investigated using immunocytochemistry. Data were analysed using one-parametric and multivariate analysis and were corrected for the potential impact of patient ...
