A dye-sensitized photocatalyst combining Pt-loaded TiO_(2) and Ru(Ⅱ)tris-diimine sensitizer(RuP)was constructed and its activity for photochemical hydrogen evolution was compared with that of Pt-intercalated HCa_(2)Nb_(3)O_(10) *** the sacrificial donor ethylenediaminetetraacetic acid(EDTA)disodium salt dihydrate was used,RuP/Pt/TiO_(2) showed higher activity than RuP/Pt/HCa_(2)Nb_(3)O_(10).In contrast,when NaI(a reversible electron donor)was used,RuP/Pt/TiO_(2) showed little activity due to back electron transfer to the electron acceptor(I_(3)-),which was gener-ated as the oxidation product of I-.By modification with anionic polymers(sodium poly(styrenesulfonate)or sodium polymethacrylate)that could inhibit the scavenging of conduction band electrons by I_(3)-,the H_(2) production activity from aqueous NaI was improved,but it did not exceed that of RuP/Pt/HCa_(2)Nb_(3)O_(10).Transient absorption measurements showed that the rate of semiconductor-to-dye back electron transfer was slower in the case of TiO_(2) than HCa_(2)Nb_(3)O_(10),but the electron transfer reaction to I3-was much *** results indicate that Pt/TiO_(2) is useful for reactions with sacrificial reductants(e.g.,EDTA),where the back electron transfer reaction to the more reducible product can be ***,more careful design of the catalyst will be nec-essary when a reversible electron donor is employed.

An anastomotic leak is one of the major complications following colorectal *** treatments for anastomotic leak are total parenteral nutrition or temporary *** over-the-scope-clipping(OTSC)system was originally developed to treat intestinal perforation or to close the tissue after natural orifice transluminal endoscopic *** cases of successful management of an anastomotic leak after colorectal surgery using the OTSC system are *** patient avoided a temporary *** the other,hospitalization was shortened by the use of the OTSC *** OTSC system can be a potential option in the management of anastomotic leaks after colorectal surgery.
