Direct arylation polycondensation of β-unprotected chalcogen heteroles under phosphine-free conditions
Autor: Shotaro Hayashi, Yoshihisa Kojima, Toshio Koizumi
Publikováno v: Polymer. 113:214-220
We have demonstrated a direct arylation polycondensation of β-unprotected chalcogen heteroles (furan, thiophene and selenophene) under phosphine-free conditions. The polycondensation of furan and thiophene using a solid-supported palladium catalyst,

Palladium on carbon-catalyzed direct C-H arylation polycondensation of 3,4-ethylenedioxythiophene with various dibromoarenes
Autor: Shotaro Hayashi, Yoshihisa Kojima, Toshio Koizumi
Publikováno v: Journal of Polymer Science Part A: Polymer Chemistry. 55:1183-1188
We have demonstrated a direct arylation polycondensation of 3,4-ethylenedioxythiophene with 2,7-dibromo-9,9-dioctylfluorene using palladium on carbon (Pd/C) as a catalyst. Pd/C is a low-cost solid-supported palladium catalyst, giving one of the effec

Successful Treatment of Epstein-Barr Virus-Associated Lymphoproliferative Disorder with Rituximab in a Patient Undergoing Immunosuppressive Therapy for Aplastic Anemia
Autor: Hiroaki Shimizu, Masahiro Mihara, Takuma Ishizaki, Hiroshi Handa, Hirono Iriuchishima, Nobuhiko Kobayashi, Yoshihisa Kojima
Publikováno v: Acta haematologica. 136(3)
Epstein-Barr virus-associated lymphoproliferative disorder (EBV-LPD) is a currently emerging serious complication in immunosuppressed patients, especially in allogeneic transplant recipients. Several fatal cases of EBV-LPD have been reported in aplas

Publikováno v: Dental Materials Journal. 31:1087-1096
In tissue engineering, biodegradable polymer materials with both high biocompatibility and high strength are very important as scaffolds for long term use. Therefore, in this research, we tried to prepare the three types of poly(L-lactic acid) (PLLA)

Removal of lens material dropped into the vitreous cavity during cataract surgery using an optical fiber-free intravitreal surgery system
Autor: Yoshiaki Shimada, Yoshihisa Kojima, Masayuki Horiguchi
Publikováno v: Journal of Cataract and Refractive Surgery. 29:1256-1259
We describe a technique for removing lens fragments dropped into the vitreous cavity during cataract surgery using an optical fiber-free intravitreal surgery system (OFFISS) that was developed for bimanual vitrectomy. The dropped nucleus was removed
