Facile synthesis of 1.3 nm monodispersed Ag nanoclusters in an aqueous solution and their antibacterial activities for .

A facile one-pot strategy was developed to prepare ultrastable monodispersed Ag nanoclusters (NCs) in aqueous solution by using ISOBAM-104, as a stabilizing agent. The as-prepared Ag NCs with an average size of 1.3 nm, which can be preserved in water solution for more than one year under ambient conditions without obvious agglomeration, exhibited excellent antibacterial activities for (DH5α), compared to most of the previously reported results.

[Effect of oxidative damage on expression of myocardin and NF-E2-related factor 2 in myocardial cells].

With the oxidative damage model established in rat myocardial cells by hydrogen peroxide (H O ), the expression of myocardin and nuclear factor erythroid 2-related factor 2 (Nrf2) during oxidative damage and effect of myocardin on Nrf2 were preliminarily explored. The expression of the target gene was increased or decreased by transfection of plasmid DNA or shRNA, respectively. Cell proliferation was detected by sulforhodamine B (SRB) assay.
