Journal ArticleDOI
Production and Characterization of a Novel Tissue-Type Plasminogen Activator Derivative in Escherichia coli
Yoshimasa Saito,Yoshinori Ishii,Hitoshi Sasaki,Masako Hayashi,Takao Fujimura,Yuko Imai,Sachiko Nakamura,Shingo Suzuki,Joji Notani,Takashi Asada,Haruo Horiai,Masakazu Kobayashi,Mineo Niwa +12 more
TL;DR: D‐K2P exhibited more potential thrombolytic effect than recombinant nt‐PA (alteplase) by both bolus and infusional administrations in the rabbit thrombus model and was also more effective in canine coronary thrombosis, which may indicate that plasma half‐life and fibrin acceleration play important roles in the thromBOlytic agent.
Journal ArticleDOI
Affinity labelling of cephalosporin C acylase from Pseudomonas sp. N176 with a substrate analogue, 7β-(6-bromohexanoylamido)cephalosporanic acid
Yoshinori Ishii,Yoshimasa Saito,Hitoshi Sasaki,Fumiaki Uchiyama,Masako Hayashi,Sachiko Nakamura,Mineo Niwa +6 more
TL;DR: Results indicate that although labelled Tyr 270 is not essential, it does play an important role in the enzymatic activity and the inactivation by 6-BH-7ACA is due to the modification of a single residue located in the neighborhood of the substrate binding region of the acylase.
Journal ArticleDOI
Cross-Neutralizing Breadth and Longevity Against SARS-CoV-2 Variants After Infections
Yuki Kurahashi,Silvia Sutandhio,Koichi Furukawa,Lidya Handayani Tjan,Sachiyo Iwata,Shigeru Sano,Yoshiki Tohma,Hiroyuki Ohkita,Sachiko Nakamura,Mitsuhiro Nishimura,Jun Arii,Tatsunori Kiriu,E. Yamamoto,Tatsuya Nagano,Yoshihiro Nishimura,Yasuko Mori +15 more
TL;DR: The results indicate that neutralizing antibodies that recognize the common epitope for several variants may be maintained for a long time, whileneutralizing antibodies having specific epitopes for a variant, produced in large quantities immediately after infection, may decrease quite rapidly.

Cross-neutralizing activity against Omicron could be obtained in SARS-CoV-2 convalescent patients who received two doses of mRNA vaccination
Yuki Kurahashi,Koichi Furukawa,Silvia Sutandhio,Lidya Handayani Tjan,Sachiyo Iwata,Shigeru Sano,Yoshiki Tohma,Hiroyuki Ohkita,Sachiko Nakamura,Mitsuhiro Nishimura,Jun Arii,Tatsunori Kiriu,E. Yamamoto,Tatsuya Nagano,Yoshihiro Nishimura,Yasuko Mori +15 more
TL;DR: It is demonstrated that at least two doses of mRNA vaccination to SARS-CoV-2 convalescent patients can induce cross-neutralizing activity against Omicron, and surprisingly and interestingly, after the second vaccination, the subject neutralizing antibody titers all became seropositive.

Masahiro Nakahara,Atsushi Arai,Sachiko Nakamura,Hiroaki Shimizu,Shigeru Sano,Akitsugu Morishita,Hideo Aihara,Takashi Sasayama +7 more
TL;DR: For example, CoVID-19 as mentioned in this paper was held in Shanghai, China in 2019, where 1.101% of the participants failed to pass the test.https://www.youtube.com/watchlist.php?list=watch.
