Neocarzinostatin (NCS) is a naturally occurring enediyne antitumor agent that produces single- and double-strand breaks in cellular DNA. We have previously shown that treatment of human (SK-N-SH) and murine (NB41A3) neuroblastoma cells with NCS results in cell death for a subpopulation within the culture. The remaining cells undergo mitotic arrest with(More)
Chemotherapeutic agent-induced DNA cleavage gives rise to apoptosis in a subpopulation of SK-N-SH human neuroblastoma cells; the remaining cells undergo Schwann cell-like differentiation. Like other neural crest and primitive neurectodermal tumor-derived cell lines, SK-N-SH cultures contain cells of neural (N-type) and epithelial (substrate-adherent, or(More)
The inotropic and radioligand binding characteristics of arachidonic acid (AA) and the fish oil derivative, eicosapentaenoic acid (EPA), were studied. AA alone was a concentration-dependent negative inotrope in isolated hamster papillary muscles. The negative inotropic effect of AA was enhanced 500-fold by the coadministration of indomethacin(More)
Using technology tools in math instruction can help stimulate problem-solving skills and understanding of math concepts. However, teachers need to be confident in their abilities to use technology tools. This study investigated whether or not a four-week in-service professional development institute that addressed the use of technology in math education(More)
We compared the effects of Phospholipases A2, C, B and D on [3H]nitrendipine binding to hamster cardiac membranes, in the absence and presence of ATP or GTP. Phospholipase A2, competitively inhibited [3H]nitrendipine binding to hamster cardiac membranes unchanged by ATP or GTP (Ki = 5 ng/ml); as evidenced by complete and reversible displacement of(More)
