    Notes: Abstract The purpose of this study was to determine the roles of calcium-dependent phospholipase A2 (cPLA2) and calcium-independent phospholipase A2 (iPLA2) in thapsigargin-induced membrane susceptibility to secretory phospholipase A2 (sPLA2) and programmed cell death. 3H-arachidonic acid release was observed in the presence of thapsigargin. This release was inhibited partially by an inhibitor of iPLA2 (BEL) and completely by an inhibitor of both cPLA2 and iPLA2 (MAFP) suggesting that these enzymes were active during apoptosis. The process of cell death did not require the activity of either enzyme since neither inhibitor impeded the progression of apoptosis. However, both inhibitors increased the susceptibility of the membrane to sPLA2 in the presence of thapsigargin. In the case of BEL, this effect appeared to involve direct induction of apoptosis in a sub-population of the cells independent of the action of iPLA2. In conclusion, the results suggested that cPLA2 and iPLA2 are active during thapsigargin-induced apoptosis in S49 cells and that cPLA2 tempers the tendency of the cells to become susceptible to sPLA2 during apoptosis.

    Notes: Abstract Aluminum is often used as a conservative tracer toseparate natural from anthropogenic components ofmetal contamination in marine sediments, butidentifying uncontaminated sites to develop baselinemetal:aluminum relationships can be problematic inpopulated areas. Here we present a new method foridentifying baseline relationships in high populationdensity areas. The method involves comparing theresidual from the metal:aluminum regression with anindependent estimate of laboratory measurement error,based on the premise that mean square error from theregression must equal laboratory measurement error forany data set that is free of anthropogenicallyenriched sites. The method is applied to data setsfrom the mid-Atlantic and Gulf coasts of the UnitedStates to test consistency in baseline relationshipsbetween these two coasts of geologically differentorigin. Differences in metal:aluminum relationshipsbetween coasts were found to be small and limited tothe least abundant trace metals.
