Determination of low levels of benzodiazepines and their metabolites in urine by hollow-fiber liquid-phase microextraction (LPME) and gas chromatography-mass spectrometry (GC-MS).
J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 975 , 24-33, (2014) In this study, it is shown a method for the determination of benzodiazepines and their main metabolites in urine samples by hollow-fiber liquid-phase microextraction (LPME) in the three-phase mode. Initially, the hydrolysis step was performed using 100 μL of ... |

Evaluation of injection methods for fast, high peak capacity separations with low thermal mass gas chromatography.
J. Chromatogr. A. 1392 , 82-90, (2015) Low thermal mass gas chromatography (LTM-GC) was evaluated for rapid, high peak capacity separations with three injection methods: liquid, headspace solid phase micro-extraction (HS-SPME), and direct vapor. An Agilent LTM equipped with a short microbore capil... |

Inhibition of miR-29 has a significant lipid-lowering benefit through suppression of lipogenic programs in liver.
Sci. Rep. 5 , 12911, (2015) MicroRNAs (miRNAs) are important regulators and potential therapeutic targets of metabolic disease. In this study we show by in vivo administration of locked nucleic acid (LNA) inhibitors that suppression of endogenous miR-29 lowers plasma cholesterol levels ... |

Determination of alkylresorcinols and their metabolites in biological samples by gas chromatography-mass spectrometry.
J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 1000 , 120-9, (2015) High throughput GC-MS methods for quantification of alkylresorcinols (AR), biomarkers of whole grain wheat and rye intake, in plasma and adipose tissue and their metabolites in urine were developed and optimised. Alkylresorcinols in plasma (200μL) and adipose... |

Octadecyl functionalized core-shell magnetic silica nanoparticle as a powerful nanocomposite sorbent to extract urinary volatile organic metabolites.
J. Chromatogr. A. 1393 , 18-25, (2015) In this present study, magnetic Fe3O4@SiO2 nanoparticles (MNPs) functionalized with octadecyl groups (Fe3O4@SiO2-C18 NPs) were synthesized, characterized and employed, for the first time, as powerful nanosorbent to extract endogenous volatile organic metaboli... |

Red:far-red light conditions affect the emission of volatile organic compounds from barley (Hordeum vulgare), leading to altered biomass allocation in neighbouring plants.
Ann. Bot. 115 , 961-70, (2015) Volatile organic compounds (VOCs) play various roles in plant-plant interactions, and constitutively produced VOCs might act as a cue to sense neighbouring plants. Previous studies have shown that VOCs emitted from the barley (Hordeum vulgare) cultivar 'Alva'... |

Mercury-induced fragmentation of n-decane and n-undecane in positive mode ion mobility spectrometry.
Analyst 140 , 6379-85, (2015) Ion mobility spectrometry is a well-known technique for trace gas analysis. Using soft ionization techniques, fragmentation of analytes is normally not observed, with the consequence that analyte spectra of single substances are quite simple, i.e. showing in ... |
