Journal ArticleDOI
Usefulness of diffusion-weighted MRI with echo-planar technique in the evaluation of cellularity in gliomas.
Takeshi Sugahara,Yukunori Korogi,Masato Kochi,Ichiro Ikushima,Yoshinori Shigematu,Toshinori Hirai,T. Okuda,Luxia Liang,Yulin Ge,Yasuyuki Komohara,Yukitaka Ushio,Mutsumasa Takahashi +11 more
TL;DR: Diffusion‐weighted MRI with EPI is a useful technique for assessing the tumor cellularity and grading of gliomas and is useful for the diagnosis and characterization ofgliomas.
Journal ArticleDOI
Correlation of MR imaging-determined cerebral blood volume maps with histologic and angiographic determination of vascularity of gliomas.
Takeshi Sugahara,Yukunori Korogi,Masato Kochi,Ichiro Ikushima,Toshinori Hirai,T. Okuda,Yoshinori Shigematsu,Luxia Liang,Yulin Ge,Yukitaka Ushio,Mutsumasa Takahashi +10 more
TL;DR: The results of perfusion-sensitive MR imaging with gradient-echo echoplanar technique correlated with both histologic and angiographic vascularities.
Journal Article
Posttherapeutic Intraaxial Brain Tumor: The Value of Perfusion-sensitive Contrast-enhanced MR Imaging for Differentiating Tumor Recurrence from Nonneoplastic Contrast-enhancing Tissue
Takeshi Sugahara,Yukunori Korogi,Seiji Tomiguchi,Yoshinori Shigematsu,Ichiro Ikushima,Tomohiro Kira,Luxia Liang,Yukitaka Ushio,Mutsumasa Takahashi +8 more
TL;DR: An enhancing lesion with a normalized rCBV ratio higher than 2.6 or lower than 0.6 may suggest tumor recurrence or nonneoplastic contrast-enhancing tissue, respectively, and 201Tl-SPECT may be useful in making the differentiation.
Journal Article
High-Efficiency in Vivo Gene Transfer Using Intraarterial Plasmid DNA Injection following in Vivo Electroporation
Toru Nishi,Kimio Yoshizato,Shigeo Yamashiro,Hideo Takeshima,Kyoichi Sato,Kazuya Hamada,Isao Kitamura,Teizo Yoshimura,Hideyuki Saya,Jun Ichi Kuratsu,Yukitaka Ushio +10 more
TL;DR: Electrogene therapy, which does not require viral genes or particles, allows genes to be transferred and expressed in desired organs or tissues, and it may lead to the development of a new type of highly effective gene therapy.
Journal ArticleDOI
CENP-A Phosphorylation by Aurora-A in Prophase Is Required for Enrichment of Aurora-B at Inner Centromeres and for Kinetochore Function
Naoko Kunitoku,Takashi Sasayama,Tomotoshi Marumoto,Dongwei Zhang,Shinobu Honda,Osamu Kobayashi,Katsuyoshi Hatakeyama,Yukitaka Ushio,Hideyuki Saya,Toru Hirota,Toru Hirota,Toru Hirota +11 more
TL;DR: The observations suggest that phosphorylation of CENP-A on Ser-7 by Aurora-A in prophase is essential for kinetochore function.
