Chromatographic impurity fingerprinting of genuine and counterfeit Cialis® as a means to compare the discriminating ability of PDA and MS detection.
supervised Partial Least Squares and its discriminant variant (PLS, PLS- DA) as well the classification methods including Soft Independent Modelling of Class Analogy (SIMCA) and the k Nearest Neighbour ...
Discriminative power of campylobacter phenotypic and genotypic typing methods
calculated by the Simpson’s index of diversity (SID) and the congruence was measured by the adjusted Rand index and adjusted Wallace coefficient. MLST was individually the most discriminative typing method for ...
Application of LC-MS/MS MRM to Determine Staphylococcal Enterotoxins (SEB and SEA) in Milk.
detected in milk samples using LC- MS / MS in MRM mode. The selected SE peptides were proteotypic for each toxin, allowing the discrimination of SEA and SEB in a single run. The detection limit of SEA and ...
Barriers and opportunities for return-to-work of cancer survivors: time for action--rapid review and expert consultation.
workers alike, and the setup of a positive discrimination employment policy for cancer survivors were acknowledged as factors facilitating RTW of cancer survivors. CONCLUSIONS: The awareness of health ...
Discriminating nicotine and non-nicotine containing e-liquids using infrared spectroscopy.
chemometrics was evaluated for the discrimination between nicotine containing and non-nicotine containing samples. It could be concluded that both ATR- IR and NIR could be used for the discrimination when ...
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.
Counterfeit Drugs Discriminant Analysis Least-Squares Analysis Monte Carlo Method Sildenafil Citrate Abstract: The aim of this work was to develop a general framework for the validation of discriminant models ...
Testing of complementarity of PDA and MS detectors using chromatographic fingerprinting of genuine and counterfeit samples containing sildenafil citrate.
i.e., 254, 270, and 290 nm, and all possible combinations of these wavelengths. First, it was verified if both groups of fingerprints can discriminate between genuine, generic, and counterfeit medicines ...
Restricted access to antiretroviral treatment for undocumented migrants: a bottle neck to control the HIV epidemic in the EU/EEA.
access to health care as a human right that should be available to everyone without discrimination. From a clinical and public health perspective, early HIV care and treatment is associated with viral ...
Prevalence, diagnosis, and disease course of pertussis in adults with acute cough: a prospective, observational study in primary care37029
respiratory samples were obtained in 3074 patients. Three per cent (93/3074) had recent B. pertussis infection. Prior cough duration >2 weeks discriminated to some extent between those with and without ...
Next-generation sequencing shows West Nile virus quasispecies diversification after a single passage in a carrion crow (Corvus corone) in vivo infection model.
next-generation sequencing resulting in an average depth of at least 700 × in each sample. Appropriate controls were sequenced to discriminate biologically relevant low-frequency variants from experimentally ...
