A 56-year-old woman complaining of right lower abdominal pain was admitted to our hospital. An abdominal computed tomography showed the enlarged appendix tip and a high density area around the appendix to retroperitoneum. The patient was diagnosis wi

We reported that per-6-folic acid (FA)-appended β-cyclodextrin (β-CyD) possessing two caproic acids between FA and a β-CyD molecule as a spacer (Fol-c2-β-CyD) could be useful as a promising antitumor drug carrier. However, the effects of the cavi

We have succeeded in accomplishing the deracemization of (±)-2-acetoxydecyl and (±)-acetoxy-6-benzyloxyhexyl tosylates, which have a long substituent, via an enzyme-mediated enantioselective hydrolysis with a Mitsunobu inversion using polymer-suppo

Conference on Lasers and Electro-Optics 2010.
High power external cavity diode lasers were developed in the wavelength region of 1µm by using single-angled facet laser diodes. 330mW output and 130nm tuning were achieved in the conventional Littman-Metcalf configuration.
