We joined the 60th. Annual Meeting of Japan Society of Cerebral Blood Flow and Metabolism in Osaka on November 3-4, 2017. Dr. Kashiwazaki, Dr. Uchino, and Prof. Kuroda presented our papers on carotid stenosis and moyamoya disease. It was my great pleasure to see Prof. Mari Dezawa from Sendai and Prof. Shinn-Zong Lin from Hualien, Taiwan. He will host the 11th. Pan Pacific Symposium on Stem Cell and Cancer Research in the next March.
