Journal ArticleDOI
Evidence of association of the ecnos gene polymorphism with plasma no metabolite levels in humans
Toshihiko Tsukada,Keitaro Yokoyama,Tomoko Arai,Fumi Takemoto,Sigeko Hara,Akira Yamada,Yoshindo Kawaguchi,Tatsuo Hosoya,Jun Igari +8 more
TL;DR: The results of this study indicate that the ecNOS4 gene locus may be responsible for variations in the genetic control of plasma NOx and that analysis of ecN OS4 gene polymorphism may be a useful tool for studying the relation between NO and diseases.
Journal ArticleDOI

Masafumi Fukagawa,Keitaro Yokoyama,Fumihiko Koiwa,Masatomo Taniguchi,Tetsuo Shoji,Junichiro James Kazama,Hirotaka Komaba,Ryoichi Ando,Takatoshi Kakuta,Hideki Fujii,Msasaaki Nakayama,Yugo Shibagaki,Seiji Fukumoto,Naohiko Fujii,Motoshi Hattori,Akira Ashida,Kunitoshi Iseki,Takashi Shigematsu,Yusuke Tsukamoto,Yoshiharu Tsubakihara,Tadashi Tomo,Hideki Hirakata,Tadao Akizawa +22 more
TL;DR: CKD-MBD Guideline Working Group, Japanese Society for Dialysis Therapy, and Tadao Akizawa thank the authors for their help and assistance in the development of this guideline.
Journal ArticleDOI
Serum phosphate and calcium should be primarily and consistently controlled in prevalent hemodialysis patients.
Masatomo Taniguchi,Masafumi Fukagawa,Naohiko Fujii,Takayuki Hamano,Tetsuo Shoji,Keitaro Yokoyama,Shigeru Nakai,Takashi Shigematsu,Kunitoshi Iseki,Yoshiharu Tsubakihara +9 more
TL;DR: As time of achieving P and Ca targets increased, all‐cause mortalities diminished incrementally, significantly; among mineral values, P would be the strongest predictor for high mortality.
Journal ArticleDOI
A nonclassical vitamin D receptor pathway suppresses renal fibrosis
Ichiaki Ito,Tsuyoshi Waku,Masato Aoki,Rumi Abe,Yu Nagai,Tatsuya Watanabe,Yuka Nakajima,Ichiro Ohkido,Keitaro Yokoyama,Hiroyuki Miyachi,Toshiyuki Shimizu,Akiko Murayama,Hiroyuki Kishimoto,Kazuo Nagasawa,Junn Yanagisawa +14 more
TL;DR: This study found that 1,25-dihydroxyvitamin D3-bound [1,25(OH)2D3- bound] vitamin D receptor (VDR) specifically inhibits TGF-β-SMAD signal transduction through direct interaction with SMAD3.
Journal ArticleDOI
Serum leptin, abdominal obesity and the metabolic syndrome in individuals with chronic spinal cord injury.
Yukio Maruyama,M Mizuguchi,T Yaginuma,M Kusaka,Hiraku Yoshida,Keitaro Yokoyama,Y Kasahara,Tatsuo Hosoya +7 more
TL;DR: SCI individuals were predisposed to excessive abdominal obesity, and higher leptin levels were strongly associated with higher prevalence of abdominal obesity in this population.
