Journal ArticleDOI
Pulmonary toxicity of well-dispersed multi-wall carbon nanotubes following inhalation and intratracheal instillation
Yasuo Morimoto,Masami Hirohashi,Akira Ogami,Takako Oyabu,Toshihiko Myojo,Motoi Todoroki,Makoto Yamamoto,Masayoshi Hashiba,Yohei Mizuguchi,Byeong Woo Lee,Etsushi Kuroda,Manabu Shimada,Wei-Ning Wang,Kazuhiro Yamamoto,Katsuhide Fujita,Shigehisa Endoh,Kunio Uchida,Norihiro Kobayashi,Kohei Mizuno,Masaharu Inada,Hiroaki Tao,Tetsuya Nakazato,Junko Nakanishi,Isamu Tanaka +23 more
TL;DR: It is shown that well-dispersed MWCNT can produce pulmonary lesions, including inflammation, and less pulmonary inflammation responses was observed, as compared to intratracheal instillation.
Journal ArticleDOI
Microwave digestion with HNO3/H2O2 mixture at high temperatures for determination of trace elements in coal by ICP-OES and ICP-MS
TL;DR: In this article, the microwave digestion method with a HNO3/H2O2 mixture for determination of 18 trace elements (Li, Be, V, Cr, Mn, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Cd, Cs, Ba, and Pb) was validated.
Journal ArticleDOI
Gene expression profiles in rat lung after inhalation exposure to C60 fullerene particles.
Katsuhide Fujita,Yasuo Morimoto,Akira Ogami,Toshihiko Myojyo,Isamu Tanaka,Manabu Shimada,Wei-Ning Wang,Shigehisa Endoh,Kunio Uchida,Tetsuya Nakazato,Kazuhiro Yamamoto,Hiroko Fukui,Masanori Horie,Yasukazu Yoshida,Hitoshi Iwahashi,Junko Nakanishi +15 more
TL;DR: Gene expression profiles revealed that few genes involved in the inflammatory response, oxidative stress, apoptosis, and metalloendopeptidase activity were up-regulated at both 3 days and 1 month post-exposure, suggesting that C(60) fullerene might not have a severe pulmonary toxicity under the inhalation exposure condition.
Journal ArticleDOI
Statistical analysis of the concentrations of trace elements in a wide diversity of coals and its implications for understanding elemental modes of occurrence
TL;DR: In this paper, the use of inductively coupled plasma optical emission spectrometry (ICP-OES) and inductive coupled plasma mass spectrometric (ICP-MS) was used for the determination of trace elements in 24 coals from worldwide deposits of differing ranks and sulfur contents.
Journal ArticleDOI
Extraction of lanthanide ions from aqueous solution by bis(2-ethylhexyl)phosphoric acid with room-temperature ionic liquids
Sang Jun Yoon,Jae Goo Lee,Hideo Tajima,Akihiro Yamasaki,Fumio Kiyono,Tetsuya Nakazato,Hiroaki Tao +6 more
TL;DR: In this article, the authors used bis(2-ethylhexyl)phosphoric acid (DEHPA) with [1-Cn-3-methylimidazolium][PF 6 ] to extract five kinds of lanthanide metal ions.
