  1. * All data from figures are estimates of the means. When these data were also present in tables, the estimates were never more than 2% different from the numbers available in the tables; table data are shown if both were available. All data with distributions are shown as Mean ± SEM. N/A indicates data were not available from the Beck et al. paper. All statistical analyses are shown as p value of difference from control (C). NS indicates not significantly different from control. S indicates significantly different from control, S1p < 0.01 vs control. S2, p < 0.02 vs control, S5 p < 0.05 vs control
