I have visited Houston to join International Stroke Conference (ISC) 2017. Last night, I met Prof. Ichiro Yabe from Department of Neurology, Hokkaido University Graduate School of Medicine, Sapporo for the first time since I moved from Sapporo to Toyama 5 years ago. Now, he is conducting an exciting research at Houston Methodist Hospital. We could really talk a lot and enjoy a dinner. I strongly hope he will complete his work here and safely come back to Sapporo!
