Chemometrics and chromatographic fingerprints to classify plant food supplements according to the content of regulated plants.
using SIMCA and PLS- DA. For each model, misclassification rates for the external test set of maximum one sample could be obtained. The models were applied to five real samples resulting in the ...
Detection of regulated herbs and plants in plant food supplements and traditional medicines using infrared spectroscopy.
misclassifications for the selected test set. For the other three a success rate of 50% was obtained. Mid- IR combined with SIMCA can therefore be applied as a first step in the screening of unknown samples, before ...
Three-dimensional aesthetic assessment of class II patients before and after orthognathic surgery and its association with quantitative surgical changes.
three-dimensional (3D) facial images, and to examine the relationship of aesthetic ratings in relation to quantitative surgical changes. Pre- and postoperative 3D facial images of 20 surgically treated class II ...
Advanced Methods for Dose and Regimen Finding During Drug Development: Summary of the EMA/EFPIA Workshop on Dose Finding (London 4-5 December 2014).
issues in drug development, as illustrated by high rates of late-stage attritions in clinical development and postmarketing commitments required by regulatory institutions. In an effort to shift the ...
The fate of buccal bone around dental implants. A 12-month postloading follow-up study.
(one stage vs. two stages) did not influence the rate of bone resorption (P = 0.23). CONCLUSION: Within the limitations of this study, one might question the necessity of having a thick bone plate at the ...
Childhood leukaemia near nuclear sites in Belgium, 2002-2008.
site of Mol-Dessel, however, two- to three-fold increased leukaemia incidence rates were found in children aged 0-14 years living in the 0-5, 0-10 and the 0-15 km proximity areas. For this site, there ...
Detection and risk evaluation of counterfeit medicines based on physico-chemical properties: the fingerprint and chemometrics approach
genuine medicines, in particular for mass and long length of tablets. CART resulted in a good distinction between genuine and illegal medicines (98.93% correct classification rate for Viagra® and 99.42% for ...
The Monte Carlo validation framework for the discriminant partial least squares model extended with variable selection methods applied to authenticity studies of Viagra® based on chromatographic impurity profiles.
specificity, correct classification rate and area under the curve in a function of model complexity. Therefore, one can quickly evaluate their uncertainty estimates. Moreover, the Monte Carlo model validation ...
Headspace-gas chromatographic fingerprints to discriminate and classify counterfeit medicines.
genuine and counterfeit drugs, and SIMCA generated the best predictive models. This technique not only resulted in a 100% correct classification rate for the discrimination between genuine and counterfeit ...
Chemometrics and chromatographic fingerprints to discriminate and classify counterfeit medicines containing PDE-5 inhibitors.
could be revealed, especially for the Viagra(®) data set. For both data sets predictive models were obtained with 100% correct classification rates for the differentiation between genuine and counterfeit ...
