However, there are only a few studies that analyzed the association with tartrate-resistant acid phosphatase 5b expression in those patients. Therefore, we analyzed the characteristics of patients with giant cell tumors of bone and high tartrate-resistant acid phosphatase 5b expression.

The anti-keloid medication tranilast is frequently used in Japan but its effectiveness for EADF is not well understood.
Methods: We retrospectively analyzed the medical records of EADF patients treated with tranilast between January 2009 and March 2021.
The first asymmetric total synthesis of (-)-hippodamine has been accomplished via the concise construction of its azaphenalene core, which is featured by the 2,4,6-chiral piperidine synthesis based on one-pot asymmetric azaelectrocyclization in the partially activated substituent system and the subsequent intramolecular Mannich reaction.
