isoprene

01/11/2023 - "However, physiological resistance to water stress in the isoprene-emitting plants was not as marked as expected in actual climate conditions, perhaps because the stress developed rapidly. "
01/11/2023 - "Here we compared the ecophysiological performances of transgenic isoprene-emitting and wild-type non-emitting tobacco plants during water stress and after re-watering in actual environmental conditions (400 ppm of CO2 and 28 °C of average daily temperature) and in a future climate scenario (600 ppm of CO2 and 32 °C of average daily temperature). "
04/09/2020 - "Contrasting behaviors were recorded for the two overexpressors under water stress, with isoprene emitters showing earlier stomatal closure (conservative behavior) than ocimene emitters (non-conservative behavior), which might suggest different induced strategies for water conservation and stress adaptation. "
01/28/2020 - "Such physiological improvement under isoprene exposure was not observed under optimal watering or severe water stress. "
01/01/2014 - "The total phenolic content was not modified under water stress whereas isoprene emissions were promoted under MS over the entire growing cycle despite the decline of Pn by 35%. "

11/29/2017 - "A comparison of samples collected serially between recovery and hypoxia time points shows a statistically significant reduction in exhaled breath isoprene (2-methyl-1,3-butadiene, log2 FC -0.399, p = 0.005, FDR = 0.034, q = 0.033), however no significant difference in isoprene abundance was observed when comparing recovery gases (21% or 100% O2, p = 0.152). "
10/30/2018 - "The detection of ethane for general oxidative stress, isoprene for hypoxia, and acetone for diabetes are considered for targeted detection. "
10/30/2018 - "The acetone (diabetes) detection is best in both sensing modes with the polymers selected by FSC; the isoprene (hypoxia) is detectable only in static sensing mode with polymers selected by FCM clustering; and the ethane (oxidative stress) detection is possible by all sensing modes and polymer selections, provided the breath samples are preconcentrated. "

01/01/2014 - "Breath isoprene, acetone, trimethylamine, acetaldehyde, and pentane were significantly higher in the NAFLD group compared with normal liver group (14.7 ppb vs. 8.9 for isoprene; 71.7 vs. 36.9 for acetone; 5.0 vs. 3.2 for trimethylamine; 35.1 vs. 26.0 for acetaldehyde; and 13.3 vs. 8.8 for pentane, P<0.05 for all). "
01/01/2014 - "Isoprene, acetone, trimethylamine, acetaldehyde, and pentane are novel biomarkers that may help to gain insight into pathophysiological processes leading to the development of NAFLD."

11/01/2000 - "virginiana Mill) are major emitters of isoprene in the southern United States, and oak populations in Texas are being dramatically reduced by oak wilt, a widespread fungal vascular disease. "

04/20/2007 - "Based on evaluations of the International Agency for Research on Cancer (IARC), isoprene has been classified in Group 2B (possibly carcinogenic to humans). "
06/01/2001 - "No epidemiologic studies are available on cancer risk from occupational exposure to isoprene. "
04/01/1997 - "All of the isoprene-induced HG neoplasms exhibited activated K-ras (60%) or H-ras (40%) mutations. "
04/01/1997 - "A higher frequency of ras mutations, in particular K-ras mutations, was detected in isoprene-induced neoplasms than in 1,3-butadiene-induced or control HG neoplasms. "
10/28/1996 - "This paper tests the EDM hypothesis using data on tumor rates in B6C3F mice administered isoprene via inhalation. "
