The inhibition of advanced glycation end-products by five fractions and three main flavonoids from Camellia nitidissima Chi flowers.
Journal of food and drug analysis
Apr 18, 2017
Camellia nitidissima Chi (CNC), belonging to Camellia genus (Theaceae family), is a medicinal and edible plant in China. Among the whole plant, the CNC flowers are especially precious, but the biological activities and the compositions of the CNC flo...
LC-MS/MS determination of d-mannose in human serum as a potential cancer biomarker.
Journal of pharmaceutical and biomedical analysis
Dec 28, 2016
Several metabolites in human serum have been identified as potential cancer biomarkers for early detection. This study focuses on the LC-MS/MS method development and validation of d-mannose in human serum. Surrogate blank serum, coupled with stable i...
Quantification of the 3α and 3β epimers of 25-hydroxyvitamin D in dried blood spots by LC-MS/MS using artificial whole blood calibration and chemical derivatization.
Talanta
Dec 28, 2016
While the biological function of the 3α epimer of 25-hydroxyvitamin D (25(OH)D) remains unknown, its presence needs to be accurately captured and separated from the main 3β epimer, to avoid positive bias in vitamin D status analyses. Several recent L...
Simultaneous determination of imperatorin and its metabolite xanthotoxol in rat plasma and urine by LC-MS/MS and its application to pharmacokinetic studies.
Journal of chromatography. B, Analytical technologies in the biomedical and life sciences
Dec 28, 2016
An accurate, precise, selective, and sensitive liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) method was developed for the simultaneous determination of imperatorin (IMP) and its metabolite, xanthotoxol (XAN), in rat plasma and ...
Rapid quantitation of avenanthramides in oat-containing products by high-performance liquid chromatography coupled with triple quadrupole mass spectrometry (HPLC-TQMS).
Food chemistry
Dec 23, 2016
Avenanthramides (AVNs) are a family of nitrogen-containing phenolic compounds produced in oat; AVN 2c, 2p, and 2f are the three major members. An LC-MS/MS method was developed, with the limit of detection (LOD) and the limit of quantitation (LOQ) bei...
An LC-MS/MS method for the determination of digitoxigenin in skin samples and its application to skin permeation and metabolic stability studies.
Journal of pharmaceutical and biomedical analysis
Dec 23, 2016
An LC-MS/MS method was developed for the determination of digitoxigenin in mice skin samples. Chromatographic separation was achieved on an Agilent Poroshell 120 EC-C18 column. Mass spectrometric detection was achieved by a triple-quadrupole mass spe...
Accelerated Solvent Extraction of Insecticides from Rice Hulls, Rice Bran, and Polished Rice Grains.
Journal of AOAC International
Dec 23, 2016
Analysis of pesticide residues in irrigated rice grains is important for food security. In this study, we analyzed accelerated solvent extraction (ASE) conditions for the extraction of thiamethoxam and chlorantraniliprole insecticides from rice hulls...
Simultaneous quantification of batrachotoxin and epibatidine in plasma by ultra-performance liquid chromatography/tandem mass spectrometry.
Legal medicine (Tokyo, Japan)
Dec 22, 2016
An ultra-performance liquid chromatography/tandem mass spectrometry (UPLC-MS/MS) method was developed and validated for the simultaneous quantification of batrachotoxin and epibatidine in plasma. Plasma samples were pretreated by liquid-liquid extrac...
Glycosaminoglycan levels in dried blood spots of patients with mucopolysaccharidoses and mucolipidoses.
Molecular genetics and metabolism
Dec 22, 2016
UNLABELLED: Mucopolysaccharidoses (MPSs) and mucolipidoses (ML) are groups of lysosomal storage disorders in which lysosomal hydrolases are deficient leading to accumulation of undegraded glycosaminoglycans (GAGs), throughout the body, subsequently r...

Graphene oxide and carboxylated graphene oxide: Viable two-dimensional nanolabels for lateral flow immunoassays.
Talanta
Dec 21, 2016
Graphene oxide (GO) and carboxylated GO were used as labels for lateral flow immunoassays, instead of the conventionally used colloidal gold and colored latex labels. A sensor is demonstrated that enables fast screening for aflatoxin B (AFB) as a mod...
