Fa yi xue za zhi
Dec 25, 2017
OBJECTIVES: To study the content variation of selegiline and its metabolites in urine, and based on actual cases, to explore the feasibility for the identification of methamphetamine abuse and selegiline use by chiral analysis.
Migration of epoxidized soybean oil from polyvinyl chloride/polyvinylidene chloride food packaging wraps into food simulants.
Environmental science and pollution research international
Dec 23, 2017
Epoxidized soybean oil (ESBO) has been used in polyvinyl chloride (PVC)/polyvinylidene chloride (PVDC) food packaging cling film as a plasticizer and stabilizer. The aim of this study was to investigate the migration of ESBO from PVC/PVDC cling film,...
Gas chromatography-mass spectrometry metabolomic study of lipopolysaccharides toxicity on rat basophilic leukemia cells.
Chemico-biological interactions
Dec 22, 2017
Lipopolysaccharide (LPS) can lead to uncontrollable cytokine production, fatal sepsis syndrome and depression/multiple organ failure, as pathophysiologic demonstration. Various toxic effects of LPS have been extensively reported, mainly on the toxici...
Extraction optimization, purification and characterization of polysaccharides from the seed coat of black soybean.
PloS one
Dec 21, 2017
In this study, the extraction of water-soluble polysaccharides from the seed coat of black soybean (BSCP) was investigated and optimized. A response surface methodology based on a Box-Behnken design (BBD) was used to optimize the extraction condition...
Chemical characterization and wound healing property of a β-D-glucan from edible mushroom Piptoporus betulinus.
International journal of biological macromolecules
Dec 20, 2017
A water-soluble β-D-glucan was obtained from fruiting bodies of Piptoporus betulinus, by hot aqueous extraction followed by freeze-thawing procedure and dialysis. Its molar mass distribution and conformational behavior in solution was assessed by siz...
Quantitative Determination of Δ9-THC, CBG, CBD, Their Acid Precursors and Five Other Neutral Cannabinoids by UHPLC-UV-MS.
Planta medica
Dec 20, 2017
Cannabinoids are a group of terpenophenolic compounds in the medicinal plant (Cannabaceae family). Cannabigerolic acid, Δ-tetrahydrocannabinolic acid A, cannabidiolic acid, Δ-tetrahydrocannabinol, cannabigerol, cannabidiol, cannabichromene, and tetr...
An alternative method to measure the diffusing capacity of the lung for carbon monoxide in infants.
Pediatric pulmonology
Dec 19, 2017
BACKGROUND: Lung diffusion assessed by the uptake of carbon monoxide (DL ) and alveolar volume (V ) by inert gas dilution are readily assessed in cooperative older subjects; however, obtaining these measurements in infants has been much more difficul...
Dual solid-phase and stir bar sorptive extraction combined with gas chromatography-mass spectrometry analysis provides a suitable tool for assaying limonene-derived mint aroma compounds in red wine.
Analytica chimica acta
Dec 12, 2017
A novel analytical method was developed for quantitative determination of eight limonene-derived monoterpenes responsible for the mint aroma in red wine. As these aromatic compounds are present at trace levels, a new dual extraction approach was prop...
[Determination of Methcathinone in Urine by GC-MS].
Fa yi xue za zhi
Oct 25, 2017
OBJECTIVES: To establish a method for the analysis of methcathinone in urine by gas chromatography-mass spectrometry （GC-MS）.
Adult fly age estimations using cuticular hydrocarbons and Artificial Neural Networks in forensically important Calliphoridae species.
Forensic science international
Oct 8, 2017
Blowflies (Diptera: Calliphoridae) are forensically important as they are known to be one of the first to colonise human remains. The larval stage is typically used to assist a forensic entomologists with adult flies rarely used as they are difficult...
