Blimp-1, a transcriptional repressor, drives the terminal differentiation of B cells to plasma cells. Using DNA microarrays, we found that introduction of Blimp-1 into B cells blocked expression of a remarkably large set of genes, while a much smaller number was induced. Blimp-1 initiated this cascade of gene expression changes by directly repressing genes(More)
Iron chelators are pluripotent neuronal antiapoptotic agents that have been shown to enhance metabolic recovery in cerebral ischemia models. The precise mechanism(s) by which these agents exert their effects remains unclear. Recent studies have demonstrated that iron chelators activate a hypoxia signal transduction pathway in non-neuronal cells that(More)
Oxidative stress has been proposed as a common mediator of apoptotic death. To investigate further the role of oxidants in this process we have studied the effects of antioxidants on Sindbis virus (SV)-induced apoptosis in two cell lines, AT-3 (a prostate carcinoma line) and N18 (a neuroblastoma line). The thiol antioxidant, N-acetylcysteine (NAC), at(More)
Catalase is an antioxidant enzyme that has been shown to inhibit apoptotic or necrotic neuronal death induced by hydrogen peroxide. We report the purification of a contaminating antiapoptotic activity from a commercial bovine liver catalase preparation by following its ability to inhibit apoptosis when applied extracellularly in multiple death paradigms.(More)

Association rules are a fundamental class of patterns that exist in data. These patterns have been widely utilized (e.g., market basket analysis) and extensive studies exist to find efficient association rule mining algorithms. Special attention is given in literature to the extension of binary association rules (e.g. among data items, is introduced. These(More)
