Journal ArticleDOI
Investigation of relationships between cell and pulp properties in Eucalyptus by examination of within-tree property variations
Toshihiro Ona,Tetsuya Sonoda,Kazuya Ito,Masaru Shibata,Yutaka Tamai,Yasuo Kojima,Jyunichi Ohshima,Shinso Yokota,Nobuo Yoshizawa +8 more
TL;DR: All cell types are important for predicting pulp properties, and it is strongly recommended that tree breeding programs for Eucalyptus include the measurement of all cell types.
Journal ArticleDOI
Buried charcoal layer and ectomycorrhizae cooperatively promote the growth of Larix gmelinii seedlings
TL;DR: Pots with a layer of charcoal in the middle of the soil profile promoted growth of the root system of the seedlings significantly more than did pots with no charcoal or with charcoal scattered throughout the soil, which suggests that buried and layered charcoal occurring in patches in post-fire stands may provide a suitable habitat for the growth of Gmelin larch seedlings.
Journal ArticleDOI
Arbuscular mycorrhizal colonization of tree species grown in peat swamp forests of Central Kalimantan, Indonesia
Keitaro Tawaraya,Y. Takaya,Maman Turjaman,Sehat Jaya Tuah,Suwido H. Limin,Yutaka Tamai,Joo Young Cha,Tadao Wagatsuma,Mitsuru Osaki +8 more
TL;DR: It is suggested that inoculation of arbuscular mycorrhizal fungi can improve the early growth of some tree species grown in peat swamp forests and this will be expected as a key technology to rehabilitate disturbed peatlands.
Journal ArticleDOI
A Phytochemical in the Edible Tamogi-take Mushroom (Pleurotus cornucopiae), D-Mannitol, Inhibits ACE Activity and Lowers the Blood Pressure of Spontaneously Hypertensive Rats
Shin-ya Hagiwara,Masayuki Takahashi,Yanbo Shen,Shinobu Kaihou,Takahiro Tomiyama,Michio Yazawa,Yutaka Tamai,Yoosu Sin,Akio Kazusaka,Minoru Terazawa +9 more
TL;DR: D-Mannitol, one of the main phytochemicals of the edible Tamogi-take mushroom (Pleurotus cornucopiae), was found to inhibit an angiotensin I converting enzyme (ACE) in spontaneously hypertensive rats (SHR) by oral administration.
Journal ArticleDOI
Honeycomb-like architecture produced by living bacteria, Gluconacetobacter xylinus
Yasumitsu Uraki,Junji Nemoto,Hiroyuki Otsuka,Yutaka Tamai,Junji Sugiyama,Takao Kishimoto,Makoto Ubukata,Hiroshi Yabu,Masaru Tanaka,Masaru Tanaka,Masatsugu Shimomura +10 more
TL;DR: Concave type honeycomb scaffold is more suitable to fabricate honeycomb-patterned BC after bacterial cellulose-producing bacterium was found to move along linear microgrooves of a stripe- patterned cellulosic scaffold.
