Journal ArticleDOI
Carbonyl Compounds Generated from Electronic Cigarettes
TL;DR: There have been reports of many hazardous chemical compounds generated from e-cigarettes, particularly carbonyl compounds such as formaldehyde, acetaldehyde, acrolein, and glyoxal which are often found in e-cigarette aerosols.
Journal ArticleDOI
Heat-not-burn tobacco product use in Japan: its prevalence, predictors and perceived symptoms from exposure to secondhand heat-not-burn tobacco aerosol
Takahiro Tabuchi,Silvano Gallus,Tomohiro Shinozaki,Tomoki Nakaya,Naoki Kunugita,Brian Colwell +5 more
TL;DR: Interest in heat-not-burn (HNB) tobacco, its prevalence, predictors of its use and symptoms from exposure to secondhand HNB tobacco aerosol in Japan are examined, finding a popular TV programme triggered IQOS diffusion in Japan.
Journal ArticleDOI
Determination of Carbonyl Compounds Generated from the E-cigarette Using Coupled Silica Cartridges Impregnated with Hydroquinone and 2,4-Dinitrophenylhydrazine, Followed by High-Performance Liquid Chromatography
TL;DR: It was elucidated that E-cigarettes incidentally generate high concentrations of carbonyl compounds, and the mean values were largely different from the median values.
Journal ArticleDOI
Bisphenol A levels in human urine.
Akiko Matsumoto,Naoki Kunugita,Kyoko Kitagawa,Toyohi Isse,Tsunehiro Oyama,Gary L Foureman,Masatoshi Morita,Toshihiro Kawamoto +7 more
TL;DR: An analytical high-performance liquid chromatography/fluorescence method is reported for BPA and its conjugate in human urine and on the application of this method in two student cohorts, finding that the urinary BPA levels in the students in 1992 were significantly higher than were those in 1999.
Journal ArticleDOI
Aldehyde dehydrogenase (ALDH) 2 associates with oxidation of methoxyacetaldehyde; in vitro analysis with liver subcellular fraction derived from human and Aldh2 gene targeting mouse.
Kyoko Kitagawa,Toshihiro Kawamoto,Naoki Kunugita,Tadasuke Tsukiyama,Kohji Okamoto,Akira Yoshida,Keiko Nakayama,Keiichi I. Nakayama +7 more
TL;DR: In vitro MALD oxidation was examined with liver subcellular fractions from Japanese subjects who carried three different ALDH2 genotypes and Aldh2 knockout mice, which suggest that ALDH 2 is a key enzyme for Mald oxidation and ME susceptibility may be influenced by the AL DH2 genotype.
