This report describes universities-industries collaborations on biomedical applications of self-organized honeycomb-patterned polymer films, which are prepared by using physical surface phenomena based on water droplet condensation during evaporation processes of polymer film casting. The film company has established engineering processes of regularly porous polymer film fabrication. The textile company has developed high-performance adhesion preventing polymer films having asymmetric nano-honeycomb structure under collaboration with the film company. Covered biliary stents are newly developed and released by the medical device company. Honeycomb-patterned polymer films are supplied to the medical device company from the film company.

インターネットではブロードバンドが普及し、動画共有サービスが、最近盛んになってきている。筆者は、大学商学部で、マルチメディアと経営情報システムとを講義している。 　この講義をより効果的にするために、マルチメディア化できないかと考え、動画共有サービスの中からユーチューブに着目して、授業中に使う試みを、この２年間試みてきた。その経過の中間報告をしようとするものである。 　今回の報告では、テレビ放送の番組録画とユーチューブによる動画配信と比較において、その長所と短所とを比較し、大学の講義における動画配信の有用性を提案するものである。

Unlike many researchers of natural product chemistry, I was fortunate to have the opportunity to study phytochemical metabolites and isolates of microbial origin. I began my career isolating the active compound(s) from the medicinal plants. After obtaining a Ph.D. degree from Tohoku University, I flew to Chicago, College of Pharmacy, University of Illinois, where I carried out research on the chemistry of acronycine and discovered several interesting chemical reactions regarding this alkaloid. After returning to Japan, I began to work at the Kitasato Institute, to search for novel antitumor antibiotics. During this period, 27 new antibiotics were isolated, and the new chemical structures were elucidated. After rejoining the Pharmaceutical Institute at Tohoku University, I again began to work on the phytochemical substances, mainly alkaloids. These studies continued after I moved to Aomori University and finally to Nihon Pharmaceutical University. I was interested in the biosynthesis of the alkaloids and found that all alkaloids could be classified into 16 classes based on their method of biosynthesis. I wrote a book about this in Japanese, and subsequently the book was translated into English as “ALKALOIDS—A Treasury of Poisons and Medicines.” After completing the publication of this book, I had many chances to write books, mainly concerning poisons and medicines. Totally, I have been able to publish 26 books regarding on these fascinating topics until now. I am feeling very satisfied with my natural product chemistry contributions, especially those of alkaloids and poisons.
