Isoprene emission by poplar is not important for the feeding behaviour of poplar leaf beetles.

BMC Plant Biol. 15 , 165, (2015)

Chrysomela populi (poplar leaf beetle) is a common herbivore in poplar plantations whose infestation causes major economic losses. Because plant volatiles act as infochemicals, we tested whether isoprene, the main volatile organic compound (VOC) produced by p...

Breath metabolite response to major upper gastrointestinal surgery.

J. Surg. Res. 193(2) , 704-12, (2015)

Esophagectomy and gastrectomy are associated with profound metabolic changes and significant postoperative morbidity. The aim of this prospective clinical study was to determine whether breath analysis can offer novel insight into the surgical metabolic respo...

The Eucalyptus terpene synthase gene family.

BMC Genomics 16 , 450, (2015)

Terpenoids are abundant in the foliage of Eucalyptus, providing the characteristic smell as well as being valuable economically and influencing ecological interactions. Quantitative and qualitative inter- and intra- specific variation of terpenes is common in...

Toxicological assessment of kretek cigarettes: Part 1: background, assessment approach, and summary of findings.

Regul Toxicol Pharmacol 70 Suppl 1 , S2-14, (2014)

This publication introduces a series of six other publications describing the toxicological assessment of kretek cigarettes, i.e., cigarettes characterized primarily by the use of a significant amount of cloves as an ingredient added to the tobacco. This pape...

A quantitative study of the influence of inhaled compounds on their concentrations in exhaled breath.

J. Breath Res. 7(1) , 017106, (2013)

Throughout the development of breath analysis research, there has been interest in how the concentrations of trace compounds in exhaled breath are related to their concentrations in the ambient inhaled air. In considering this, Phillips introduced the concept...

Isoprenoids and phenylpropanoids are part of the antioxidant defense orchestrated daily by drought-stressed Platanus × acerifolia plants during Mediterranean summers.

New Phytol. 207 , 613-26, (2015)

The hypothesis was tested that isoprenoids and phenylpropanoids play a prominent role in countering photooxidative stress, following the depletion of antioxidant enzyme activity in plants exposed to severe drought stress under high solar irradiance and high t...

The use of isoprene as a novel dopant in negative ion atmospheric pressure photoionization mass spectrometry coupled to high-performance liquid chromatography.

Rapid Commun. Mass Spectrom. 29 , 1031-8, (2015)

As in the case with positive ion atmospheric pressure photoionization (PI-APPI), the addition of dopants significantly improves the sensitivity of negative ion APPI (NI-APPI). However, the research on dopant-assisted-NI-APPI has been quite limited compared to...

COCONUT—An Efficient Tool for Estimating Copolymer Compositions from Mass Spectra.

Anal. Chem. 87 , 5223-31, (2015)

The accurate characterization of synthetic polymer sequences represents a major challenge in polymer science. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is frequently used for the characterization of copolymer ...

Electrospun nitric oxide releasing bandage with enhanced wound healing.

Acta Biomater. 13 , 121-30, (2015)

Research has shown that nitric oxide (NO) enhances wound healing. The incorporation of NO into polymers for medical materials and surgical devices has potential benefits for many wound healing applications. In this work, acrylonitrile (AN)-based terpolymers w...

Probing the mechanism of 1,4-conjugate elimination reactions catalyzed by terpene synthases.

J. Am. Chem. Soc. 134(51) , 20844-8, (2012)

The reaction mechanisms of (E)-β-farnesene synthase (EBFS) and isoprene synthase (ISPS), enzymes that catalyze a formal regiospecific 1,4-conjugate elimination of hydrogen diphosphate from (E,E)-farnesyl and dimethylallyl diphosphate (FDP and DMADP) to genera...
