Matrix solid-phase dispersion of polybrominated diphenyl ethers and their hydroxylated and methoxylated analogues in lettuce, carrot and soil.

A Iparraguirre et al.

Journal of chromatography. A, 1360, 57-65 (2014-08-19)

In the present work, a novel analytical method for the simultaneous determination of ten polybrominated diphenyl ethers (PBDEs), eight methoxylated PBDEs (MeO-PBDEs) and seven hydroxylated PBDEs (OH-PBDEs) in soil, lettuce and carrot samples was developed. The procedure was based on

Boosting D-lactate production in engineered cyanobacteria using sterilized anaerobic digestion effluents.

Whitney D Hollinshead et al.

Bioresource technology, 169, 462-467 (2014-08-02)

Anaerobic digestion (AD) is an environmentally friendly approach to waste treatment, which can generate N and P-rich effluents that can be used as nutrient sources for microalgal cultivations. Modifications of AD processes to inhibit methanogenesis leads to the accumulation of

Maternal, placental and fetal exposure to bisphenol A in women with and without preeclampsia.

François Leclerc et al.

Hypertension in pregnancy, 33(3), 341-348 (2014-04-15)

We aimed to investigate potential association between the exposure of bisphenol A (BPA) and preeclampsia. Concentrations of BPA were assessed in 58 pregnancies including 35 normotensive and 23 preeclamptic women, using a highly sensitive gas chromatography-mass spectrometry (GC-MS) method. BPA

Development and validation of a GC/MS method for the simultaneous determination of levetiracetam and lamotrigine in whole blood.

Panagiota Nikolaou et al.

Journal of pharmaceutical and biomedical analysis, 102, 25-32 (2014-09-23)

A sensitive and accurate gas chromatography-mass spectrometric method was developed and validated for the simultaneous determination of levetiracetam and lamotrigine in whole blood. A solid-phase extraction (SPE) procedure using HF Bond Elut C18 columns followed by derivatization using N-methyl-N-tert-butyldimethylsilyl-trifluoroacetamide (MTBSTFA)

The Application of a single-column GC--MS-MS method for the rapid analysis of chemical warfare agents and breakdown products

Young SA, et al.},

Journal of Analytical Toxicology, 43(3), 179-187 (2019)

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).

André Valle de Bairros et al.

Journal of chromatography. B, Analytical technologies in the biomedical and life sciences, 975, 24-33 (2014-12-03)

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 sodium

Hepatic and fecal metabolomic analysis of the effects of Lactobacillus rhamnosus GG on alcoholic fatty liver disease in mice.

Xue Shi et al.

Journal of proteome research, 14(2), 1174-1182 (2015-01-17)

The interactions among the gut, liver, and immune system play an important role in liver disease. Probiotics have been used for the treatment and prevention of many pathological conditions, including liver diseases. Comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GC×GC-TOF

Integrated metabolic flux and omics analysis of Synechocystis sp. PCC 6803 under mixotrophic and photoheterotrophic conditions.

Tsubasa Nakajima et al.

Plant & cell physiology, 55(9), 1605-1612 (2014-06-28)

Cyanobacteria have flexible metabolic capability that enables them to adapt to various environments. To investigate their underlying metabolic regulation mechanisms, we performed an integrated analysis of metabolic flux using transcriptomic and metabolomic data of a cyanobacterium Synechocystis sp. PCC 6803

Protein enrichment of an Opuntia ficus-indica cladode hydrolysate by cultivation of Candida utilis and Kluyveromyces marxianus.

Gabriel B Akanni et al.

Journal of the science of food and agriculture, 95(5), 1094-1102 (2014-11-06)

The cladodes of Opuntia ficus-indica (prickly pear cactus) have a low protein content; for use as a balanced feed, supplementation with other protein sources is therefore desirable. We investigated protein enrichment by cultivation of the yeasts Candida utilis and Kluyveromyces

4-Methoxymethyl-2,3,5,6-tetrafluorobenzyl alcohol as a urinary biomarker for monitoring of metofluthrin, a fluorine-containing pyrethroid, in exposed rats.

Toshiaki Yoshida

Biomarkers : biochemical indicators of exposure, response, and susceptibility to chemicals, 20(1), 71-76 (2015-01-15)

A fluorine-containing pyrethroid metofluthrin is widely used recently in mosquito repellents. The urinary excretion kinetics of its metabolites was evaluated in rats to establish an optimal biomarker for monitoring metofluthrin exposure of the general population. After metofluthrin had been administered

Fabric phase sorptive extraction: a new sorptive microextraction technique for the determination of non-steroidal anti-inflammatory drugs from environmental water samples.

Inés Racamonde et al.

Analytica chimica acta, 865, 22-30 (2015-03-04)

Fabric phase sorptive extraction (FPSE) is a new, yet very promising member of the sorbent-based sorptive microextraction family. It has simultaneously improved both the extraction sensitivity and the speed of the extraction by incorporating high volume of sol-gel hybrid inorganic-organic

High-energy chemistry of formamide: a unified mechanism of nucleobase formation.

Martin Ferus et al.

Proceedings of the National Academy of Sciences of the United States of America, 112(3), 657-662 (2014-12-10)

The coincidence of the Late Heavy Bombardment (LHB) period and the emergence of terrestrial life about 4 billion years ago suggest that extraterrestrial impacts could contribute to the synthesis of the building blocks of the first life-giving molecules. We simulated

Escherichia coli W shows fast, highly oxidative sucrose metabolism and low acetate formation.

Sugarcane is the most efficient large-scale crop capable of supplying sufficient carbon substrate, in the form of sucrose, needed during fermentative feedstock production. However, sucrose metabolism in Escherichia coli is not well understood because the two most common strains, E.

Microextraction of non-steroidal anti-inflammatory drugs from waste water samples by rotating-disk sorptive extraction.

Valentina Manzo et al.

Talanta, 128, 486-492 (2014-07-26)

In this study, six non-steroidal anti-inflammatory drugs (NSAIDs) were extracted from water samples using the rotating-disk sorptive extraction (RDSE) technique. The extraction disk device contains a central cavity that allows for the incorporation of a powdered sorbent phase (Oasis™ HLB).
