Chemometrics and chromatographic fingerprints to classify plant food supplements according to the content of regulated plants.

supplements are gaining popularity, resulting in a broader spectrum of available products and an increased consumption. Next to the problem of adulteration of these products with synthetic drugs the presence of ...

Detection of regulated herbs and plants in plant food supplements and traditional medicines using infrared spectroscopy.

combination of both. The results show that the screening of herbal preparations or plant food supplements for specific plants, using infrared spectroscopy, is feasible. The best model was obtained with the Mid- ...

Prevalence of Age-Related Macular Degeneration in Europe: The Past and the Future.

neovascularization (CNV). MAIN OUTCOME MEASURES: Prevalence of early and late AMD, BCVA, and number of AMD  cases. RESULTS: Prevalence of early AMD increased from 3.5% (95% confidence interval [CI] 2.1%-5.0%) in those ...

Zona pellucida gene mRNA expression in human oocytes is related to oocyte maturity, zona inner layer retardance and fertilization competence.

and cycle characteristics. MAIN RESULTS AND THE ROLE OF CHANCE: Oocytes contained ZP1 /⅔ and 4 mRNA while in CC only ZP3 was quantifiable. Also ZP3 protein was detected in human CC. When comparing ...

An application of mass spectrometry for quality control of biologicals: Highly sensitive profiling of plasma residuals in human plasma-derived immunoglobulin.

angiotensinogen, antithrombin- III, complement component C8, …). Those results emphasize that MS screening is a relevant first-line test to prevent any undesired concentration of plasma impurities after a plasma ...

The fate of buccal bone around dental implants. A 12-month postloading follow-up study.

19 were placed following a one-stage protocol and 12 following a two-stage protocol. RESULTS: The mean reduction in buccal bone thickness, when all groups pooled, was 0.26, 0.36, 0.35 and 0.27 mm at ...

Pesticide Residues on Three Cut Flower Species and Potential Exposure of Florists in Belgium.

Results show that roses are the most contaminated cut flowers; with an average of 14 substances detected per sample and a total concentration per rose sample of 26 mg/kg. Some active substances present an ...

Inter-laboratory study of human in vitro toxicogenomics-based tests as alternative methods for evaluating chemical carcinogenicity: a bioinformatics perspective.

Humans Kidney Tubules, Proximal Laboratory Proficiency Testing Liver Observer Variation Oligonucleotide Array Sequence Analysis Reproducibility of Results Risk Assessment Time Factors Toxicogenetics ...

Chromatographic impurity fingerprinting of genuine and counterfeit Cialis® as a means to compare the discriminating ability of PDA and MS detection.

270 nm perfect models were gained by PLS- DA and SIMCA, which is very similar to the results obtained for PDA alone. These results show that both detectors have a potential to reveal chemical ...
