Asynchrony between Antarctic temperature and CO2 associated with obliquity over the past 720,000 years
Autor: Ryu Uemura, Hideaki Motoyama, Valérie Masson-Delmotte, Jean Jouzel, Kenji Kawamura, Kumiko Goto-Azuma, Shuji Fujita, Takayuki Kuramoto, Motohiro Hirabayashi, Takayuki Miyake, Hiroshi Ohno, Koji Fujita, Ayako Abe-Ouchi, Yoshinori Iizuka, Shinichiro Horikawa, Makoto Igarashi, Keisuke Suzuki, Toshitaka Suzuki, Yoshiyuki Fujii
Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-11 (2018)
The Antarctic temperature record displays a puzzling asynchrony with changes in CO2 through glacial cycles. Here, the authors show that a 720,000-year Antarctic temperature record is affected by variations in obliquity-induced local insolation that a

Improvements in methods of analyzing dust concentrations, and influence of the storage processes on dust concentrations in polar snow and ice samples
Autor: Takayuki Miyake, Hironobu Yamada, Kumiko Goto-Azuma, Takayuki Kuramoto, Motohiro Hirabayashi, Hideaki Motoyama
Publikováno v: Antarctic Record, Vol 58, Iss 2, Pp 150-180 (2014)
We sought to improve the analytical methods employed when operating a laser particle counter and to evaluate the influence of the storage processes on dust concentrations in polar snow and ice samples. We corrected the particle size ranges and thresh

A study of the decontamination procedures used for chemical analysis of polar deep ice cores
Autor: Takayuki Miyake, Motohiro Hirabayashi, Ryu Uemura, Kumiko Goto-Azuma, Hideaki Motoyama
Publikováno v: Antarctic Record, Vol 53, Iss 3, Pp 259-282 (2009)
We investigated the decontamination procedures used on polar deep ice cores before chemical analyses such as measurements of the concentrations of iron species and dust (microparticles). We optimized cutting and melting protocols for decontamination

The fasting 13C-glucose breath test is a more sensitive evaluation method for diagnosing hepatic insulin resistance as a cardiovascular risk factor than HOMA-IR

Publikováno v: Clinica Chimica Acta. 500:20-27
Background Although we previously reported the fasting 13C-glucose breath test (FGBT) was useful for the diagnosis of hepatic insulin resistance (IR), there has been no report in an actual clinical setting. We therefore performed the FGBT in patients

Autor: Tomohiro, Komatsu, Yuka, Katsurada, Kazuya, Miyashita, Satomi, Abe, Takafumi, Nishida, Yasuhiro, Endo, Manami, Teramoto, Kei, Sasaki, Junko, Arakawa, Makoto, Sasaki, Natsuko, Suzuki, Koji, Kuwata, Toshihiko, Imakiire, Takayuki, Miyake, Masami, Sakurada, Susumu, Matsukuma, Tsutomu, Hirano, Yoshinari, Uehara, Katsunori, Ikewaki
Publikováno v: Journal of Atherosclerosis and Thrombosis.
Lecithin-cholesterol acyltransferase (LCAT) plays a significant role in the progression from premature to mature high-density lipoprotein (HDL) in circulation. Consequently, primary or secondary LCAT deletion or reduction naturally results in low ser

Publikováno v: Nature Communications
Nature Communications, Vol 10, Iss 1, Pp 1-7 (2019)
Marine biogenic sulphur affects Earth’s radiation budget and may be an indicator of primary productivity in the Southern Ocean, which is closely related to atmospheric CO2 variability through the biological pump. Previous ice-core studies in Antarc
