Excessive poly(ADP-ribose) polymerase-1 (PARP-1) activation plays a significant role in ischemic brain damage. Increasing evidence has supported the hypothesis that PARP-1 induces cell death by depleting intracellular NAD+. Based on our in vitro finding that NAD+ treatment can abolish PARP-1-mediated cell death, we hypothesized that NAD+ administration may(More)
Cumulative evidence has indicated a critical role of poly(ADP-ribose) polymerase-1 activation in ischemic brain damage. Poly(ADP-ribose) glycohydrolase (PARG) is a key enzyme in poly(ADP-ribose) catabolism. Our previous studies showed that PARG inhibitors, gallotannin (GT) and nobotanin B, can profoundly decrease oxidative cell death in vitro. Here, we(More)
BACKGROUND Effective recovery from functional impairments caused by traumatic brain injury (TBI) requires appropriate rehabilitation therapy. Multiple pathways are involved in secondary injury and recovery suggesting a role for multimodal approaches. OBJECTIVE Here, we examined the efficacy of the anti-inflammatory agent minocycline and botulinum toxin(More)
Catheter-associated urinary tract infection (CAUTI) is a common nosocomial device-associated infection. It is now recognized that the high infection rates were caused by the formation of biofilm on the surface of the catheters that decreases the susceptibility to antibiotics and results in anti-microbial resistance. In this study, we performed an in vitro(More)
DNA fragmentation and nuclear condensation are important nuclear changes in apoptosis. In this study we determined whether DNA fragmentation and nuclear condensation occur in astrocytes treated with 100-200 microM of the genotoxic agent M-nitroso-N-nitroguanidine (MNNG). Our study also investigated the roles of Ca(2+)-Mg(2+)-dependent endonuclease (CME) in(More)
