A method for quantification of volatile organic compounds in blood by SPME-GC-MS/MS with broader application: From non-occupational exposure population to exposure studies.

J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 992 , 76-85, (2015)

Humans are continuously exposed to volatile organic compounds (VOCs) as these chemicals are ubiquitously present in most indoor and outdoor environments. In order to assess recent exposure to VOCs for population-based studies, VOCs are measured in the blood o...

Cheminformatics analysis of assertions mined from literature that describe drug-induced liver injury in different species.

Chem. Res. Toxicol. 23 , 171-83, (2010)

Drug-induced liver injury is one of the main causes of drug attrition. The ability to predict the liver effects of drug candidates from their chemical structures is critical to help guide experimental drug discovery projects toward safer medicines. In this st...

QSPR modeling of octanol/water partition coefficient for vitamins by optimal descriptors calculated with SMILES.

Eur. J. Med. Chem. 43 , 714-40, (2008)

Simplified molecular input line entry system (SMILES) has been utilized in constructing quantitative structure-property relationships (QSPR) for octanol/water partition coefficient of vitamins and organic compounds of different classes by optimal descriptors....

Air to lung partition coefficients for volatile organic compounds and blood to lung partition coefficients for volatile organic compounds and drugs.

Eur. J. Med. Chem. 43 , 478-85, (2008)

Values of in vitro gas to lung partition coefficients, K(lung), of VOCs have been collected from the literature. For 44 VOCs, application of the Abraham solvation equation to log K(lung) yielded a correlation with R(2)=0.968 and S.D.=0.25 log units. Combinati...

We report the synthesis of alloyed quaternary and quinary nanocrystals based on copper chalcogenides, namely, copper zinc selenide-sulfide (CZSeS), copper tin selenide-sulfide (CTSeS), and copper zinc tin selenide-sulfide (CZTSeS) nanoplatelets (NPLs) (∼20 nm...

Rapid determination of polycyclic aromatic hydrocarbons in grilled meat using microwave-assisted extraction and dispersive liquid-liquid microextraction coupled to gas chromatography-mass spectrometry.

Meat Science 103 , 61-7, (2015)

A simple and rapid analytical tech nique for the simultaneous determination of 16 polycyclic aromatic hydrocarbons (PAHs) in grilled meat was developed using microwave-assisted extraction and dispersive liquid-liquid microextraction (MAE-DLLME) followed by ga...

Extraction and Analysis of Methadone in Exhaled Breath Condensate Using a Validated LC-UV Method.

J. Pharm. Pharm. Sci. 18 , 207-19, (2015)

A combined microextraction and separation method is presented for the determination of methadone in exhaled breath condensate (EBC) which is a promising non-invasive biological component for monitoring drug concentrations.In this work, dispersive liquid-liqui...

Development of QSAR models for predicting hepatocarcinogenic toxicity of chemicals.

Eur. J. Med. Chem. 44 , 3658-64, (2009)

A dataset comprising 55 chemicals with hepatocarcinogenic potency indices was collected from the Carcinogenic Potency Database with the aim of developing QSAR models enabling prediction of the above unwanted property for New Chemical Entities. The dataset was...

Determination of carbohydrates in tobacco by pressurized liquid extraction combined with a novel ultrasound-assisted dispersive liquid-liquid microextraction method.
