Systematic synthetic study of four diastereomerically distinct limonene-1,2-diols and their corresponding cyclic carbonates
Autor: Hiroshi Morikawa, Jun-ichi Yamaguchi, Shun-ichi Sugimura, Masato Minamoto, Yuuta Gorou, Hisatoyo Morinaga, Suguru Motokucho
Publikováno v: Beilstein Journal of Organic Chemistry, Vol 15, Iss 1, Pp 130-136 (2019)
In order to produce versatile and potentially functional terpene-based compounds, a (R)-limonene-derived diol and its corresponding five-membered cyclic carbonate were prepared. The diol (cyclic carbonate) comprises four diastereomers based on the st

Influences of tooth flank finishing after fine particle shot peening on tooth surface texture and fatigue life of vacuum carbonitrided gears
Autor: Hiroshi MORIKAWA, Kentaro NISHIYAMA, Masahiko NAKAE
Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 86, Iss 887, Pp 20-00090-20-00090 (2020)
Vacuum carbonitriding has recently been attracting attention as a heat treatment to reduce the size and weight of power transmissions. In this study, all of the chromium molybdenum steel test gears were vacuum carbonitrided after hobbing. The roughne

Pharmacokinetics and safety after once and twice a day doses of meclizine hydrochloride administered to children with achondroplasia.
Autor: Hiroshi Kitoh, Masaki Matsushita, Kenichi Mishima, Tadashi Nagata, Yasunari Kamiya, Kohei Ueda, Yachiyo Kuwatsuka, Hiroshi Morikawa, Yasuhiro Nakai, Naoki Ishiguro
Publikováno v: PLoS ONE, Vol 15, Iss 4, p e0229639 (2020)
Achondroplasia (ACH) is the most common short-limbed skeletal dysplasia caused by activating mutations in the fibroblast growth factor receptor 3 (FGFR3) gene. We identified that meclizine hydrochloride inhibited FGFR3 signaling in various chondrocyt

Development of the Center-Less Gear Lapping Machine and the Lapped Gears
Autor: Masahiko NAKAE, Kazunori HIDAKA, Hiroshi MORIKAWA, Tenji TORII, Susumu SAO
Publikováno v: Journal of Advanced Mechanical Design, Systems, and Manufacturing, Vol 5, Iss 3, Pp 160-170 (2011)
The objective of this present study is to develop a center-less gear lapping machine that can simultaneously smooth all of tooth flanks of a steel gear to a maximum peak-valley height ( Rz ) of less than 1 µm in a short time without fixing the gear

A Randomized Double-Blind Comparative Study of Sublingual Immunotherapy for Cedar Pollinosis
Autor: Kimihiro Okubo, Minoru Gotoh, Shigeharu Fujieda, Mitsuhiro Okano, Hirokazu Yoshida, Hiroshi Morikawa, Keisuke Masuyama, Yoshitaka Okamoto, Makoto Kobayashi
Publikováno v: Allergology International, Vol 57, Iss 3, Pp 265-275 (2008)
Background: Seasonal allergic rhinitis (SAR) induced by Japanese cedar pollen is a substantial problem in Japan. Sublingual immuno-therapy (SLIT) is safer than conventional antigen-specific immunotherapy, the only treatment modality by which complete

Novel Polyurethane-Catalyzed Cyclic Carbonate Synthesis Using CO2 and Epoxide
Autor: Hiroshi Morikawa, Suguru Motokucho, Rumi Satoh, Yuya Takenouchi, Hisayuki Nakatani
Publikováno v: ACS Sustainable Chemistry & Engineering. 8:4337-4340
The conversion of industrially produced greenhouse gases, like CO2, into value-added chemicals is economically beneficial to industry and vital for environmental conservation. However, the conditions for these conversions must themselves be sustainab

Poly(hydroxyurethane): catalytic applicability for the cyclic carbonate synthesis from epoxides and CO2
Autor: Hiroshi Morikawa, Suguru Motokucho
Publikováno v: Chemical Communications. 56:10678-10681
We have developed a synthetic methodology using poly(hydroxyurethane) as an organocatalyst for the chemical fixation of CO2 into epoxides, leading to the formation of five-membered cyclic carbonates with remarkably high selectivity and yields. The ca
