Accuracy of linear measurements using three imaging modalities: two lateral cephalograms and one 3D model from CBCT data.
SOFTWARE Abstract: BACKGROUND: The aim of this study was to evaluate the accuracy of linear measurements on three imaging modalities: lateral cephalograms from a cephalometric machine with ...
Detection of sibutramine in adulterated dietary supplements using attenuated total reflectance-infrared spectroscopy.
a need for easy to use equipment and techniques to perform an initial screening of samples. Attenuated total reflectance-infrared (ATR- IR) spectroscopy was evaluated for the detection of sibutramine in ...
Detection of whitening agents in illegal cosmetics using attenuated total reflectance-infrared spectroscopy.
attenuated total reflectance-infrared (ATR- IR) spectroscopy, combined with chemometrics, was evaluated for that purpose. It was found that the combination of ATR- IR with the simple chemometric technique ...
Headspace-gas chromatographic fingerprints to discriminate and classify counterfeit medicines.
guaranteed. Today, the safety evaluation of counterfeit medicines is mainly based on the identification and quantification of the active substances present. However, the analysis of potential toxic secondary ...
Agreement between cone beam computed tomography images and panoramic radiographs for initial orthodontic evaluation.
tomography (CBCT) and panoramic radiographs for initial orthodontic evaluation. This study was not meant to test differences between imaging modalities or to indicate superiority of one technique. STUDY ...
Chemometrics and chromatographic fingerprints to discriminate and classify counterfeit medicines containing PDE-5 inhibitors.
genuine and counterfeit samples of Viagra(®) and Cialis(®) were evaluated for their use in the detection and classification of counterfeit samples of these groups of medicines. Therefore several exploratory ...
Classification trees based on infrared spectroscopic data to discriminate between genuine and counterfeit medicines
built with the Classification And Regression Tree algorithm were evaluated for modelling infrared spectroscopic data in order to discriminate between genuine and counterfeit drug samples and to classify ...
