N1 - Funding Information:
I thank the participants at the Helsinki Nag Hammadi Seminars for commenting on early drafts of my dissertation, especially Prof. Ismo Dunderberg, Ulla Tervahauta and Päivi Vähäkangas for their comments and very good company. At the same time, I send heartfelt thanks to all members of the Nordic Network of Nag Hammadi and Gnosticism (NNGN). The network was funded by NordForsk from 2004–2008, and directed by Prof. Einar Thomassen, Antti Marjanen and Nils Arne Pedersen. The annual seminars have provided an outstanding foundation for young scholars to grow and make good friends and colleagues across countries. I especially wish to thank Christian Bull, René Falkenberg, Lance Jenott, Hugo Lundhaug, and Tuomas Rasimus who have made our meetings unforgettable in many ways. I also thank Katrine Brix, Nanna Liv Olsen and Sara Møldrup Thejls for excellent Coptic sisterhood.

N2 - Ultraviolet (UV) light was irradiated in air for 1 h on titania (anatase) films sol-gel derived on Ti, stainless steel, alumina, and glass slide substrates, coded as C5Ti, C5SUS, C5Al2O3 and C5GS, respectively. They were then soaked in a simulated body fluid (SBF, Kokubo solution) and their apatite-forming ability (bioactivity) was evaluated. UV light irradiated C5SUS deposited bone-like apatite within 7 days whereas C5SUS did not within 7 days. Moreover, the apatite was deposited faster on UV light irradiated C5Ti than on C5Ti without UV light irradiation, whereas UV light irradiated C5GS, C5A12O3 and C5GS did not apatite within 7 days. Therefore, the ultraviolet light irradiation was confirmed to enhance in vitro apatite-forming ability of the sol-gel derived titania films on various substrates, but the effect depended on substrates.
