BACKGROUND/AIM The hepatitis B virus (HBV) infection is accompanied by the induction of oxidative stress, especially mediated by HBV X protein (HBx). Oxidative stress has been implicated in a series of pathological states, such as DNA damage, cell survival and apoptosis. However, the host factor by which cells protect themselves under this oxidative stress(More)
We previously reported that SIRT1, an NAD+-dependent deacetylase belonging to the class III histone deacetylases, enhances hepatitis virus B (HBV) replication by targeting the transcription factor AP-1. However, the potential antiviral effects of nicotinamide, a SIRT1 inhibitor, have not yet been explored. In this study, we show that nicotinamide exhibits(More)
The decay psi(2S)-->K(0)(S)K(0)(L) is observed using psi(2S) data collected with the Beijing Spectrometer at the Beijing Electron-Positron Collider; the branching fraction is determined to be B(psi(2S)-->K(0)(S)K(0)(L))=(5.24+/-0.47+/-0.48)x10(-5). Compared with J/psi-->K(0)(S)K(0)(L), the psi(2S) branching fraction is enhanced relative to the prediction of(More)
