Olfactometry Profiles and Quantitation of Volatile Sulfur Compounds of Swiss Tilsit Cheeses.

J. Agric. Food Chem. 63 , 7511-21, (2015)

To establish the odor profiles of three differently fabricated commercial Swiss Tilsit cheeses, analyses were conducted using headspace solid-phase microextraction gas chromatography-mass spectrometry/pulsed flame photometric detection and gas chromatography-...

GC/MS method for determining carbon isotope enrichment and concentration of underivatized short-chain fatty acids by direct aqueous solution injection of biogas digester samples.

Talanta 143 , 56-63, (2015)

In anaerobic digestion of organic matter, several metabolic pathways are involved during the simultaneous production and consumption of short-chain fatty acids (SCFA) in general and acetate in particular. Understanding the role of each pathway requires both t...

A predictive ligand-based Bayesian model for human drug-induced liver injury.

Drug Metab. Dispos. 38 , 2302-8, (2010)

Drug-induced liver injury (DILI) is one of the most important reasons for drug development failure at both preapproval and postapproval stages. There has been increased interest in developing predictive in vivo, in vitro, and in silico models to identify comp...

Protic ionic liquids (PILs) nanostructure and physicochemical properties: development of high-throughput methodology for PIL creation and property screens.

Phys. Chem. Chem. Phys. 17(4) , 2357-65, (2014)

A high-throughput approach was developed in order to prepare and dry a series of protic ionic liquids (PILs) from 48 Brønsted acid-base combinations. Many combinations comprised an alkyl carboxylic acid paired with an alkyl amine. Visual screens were develope...

Detection of autosomal dominant polycystic kidney disease by NMR spectroscopic fingerprinting of urine.

Kidney Int. 79(11) , 1244-53, (2011)

Autosomal dominant polycystic kidney disease (ADPKD) is a frequent cause of kidney failure; however, urinary biomarkers for the disease are lacking. In a step towards identifying such markers, we used multidimensional-multinuclear nuclear magnetic resonance (...

Mosquito odorant receptor for DEET and methyl jasmonate.

Proc. Natl. Acad. Sci. U. S. A. 111(46) , 16592-7, (2014)

Insect repellents are important prophylactic tools for travelers and populations living in endemic areas of malaria, dengue, encephalitis, and other vector-borne diseases. DEET (N,N-diethyl-3-methylbenzamide) is a 6-decade-old synthetic repellent, which is st...

Direct Derivatization vs Aqueous Extraction Methods of Fecal Free Fatty Acids for GC-MS Analysis.

Lipids 50 , 681-9, (2015)

A comprehensive and accurate determination of free fatty acids (FFA) is required for fecal metabolomic investigations. The present study compares three aqueous extraction methods (1) ULTRA-TURRAX(®), (2) whirl mixing and (3) basic ULTRA-TURRAX extraction of f...

Dietary pectin-derived acidic oligosaccharides improve the pulmonary bacterial clearance of Pseudomonas aeruginosa lung infection in mice by modulating intestinal microbiota and immunity.

J. Infect. Dis. 211(1) , 156-65, (2015)

A predominantly T-helper type 2 (Th2) immune response is critical in the prognosis of pulmonary Pseudomonas aeruginosa infection. But the mucosal and systemic immune responses can be influenced by the intestinal microbiota.We assessed the effect of microbiota...

Influence of a Neighboring Charged Group on Hydrophobic Hydration Shell Structure.

J. Phys. Chem. B 119 , 9417-22, (2015)

Raman multivariate curve resolution (Raman-MCR), as well as quantum and classical calculations, are used to probe water structural changes in the hydration shells of carboxylic acids and tetraalkyl ammonium ions with various aliphatic chain lengths. The resul...

Molecular modifications on carboxylic acid derivatives as potent histone deacetylase inhibitors: Activity and docking studies.

Bioorg. Med. Chem. 17 , 5219-28, (2009)

In the light of known HDAC inhibitors, 33 carboxylic acid derivatives were tested to understand the structural requirements for HDAC inhibition activity. Several modifications were applied to develop the structure-activity relationships of carboxylic acid HDA...
