Comparison of tomatillo and tomato volatile compounds in the headspace by selected ion flow tube mass spectrometry (SIFT-MS).
J. Food Sci. 75(3) , C268-73, (2010) The concentration of 31 volatiles were measured in the headspace of tomatillos using selected ion flow tube-mass spectrometry (SIFT-MS), and were compared with those in vine-ripened tomato, roma tomato, cherry tomato, and grape tomato. None of the volatiles w... |

Multiple cation channels mediate increases in intracellular calcium induced by the volatile irritant, trans-2-pentenal in rat trigeminal neurons.
Cell. Mol. Neurobiol. 30(1) , 35-41, (2010) Trans-2-Pentenal (pentenal), an alpha,beta-unsaturated aldehyde, induces increases in [Ca(2+)](i) in cultured neonatal rat trigeminal ganglion (TG) neurons. Since all pentenal-sensitive neurons responded to a specific TRPA1 agonist, allyl isothiocyanate (AITC... |
