PURPOSE This study aims to investigate the effect of the ethyl acetate extract of the dried heartwood of Caesalpinia sappan L. (C-A-E) on induction of apoptosis and promotion of differentiation in vitro and anti-AML activity in vivo. STUDY DESIGN/METHODS The aqueous extract was sequentially separated with solvents of increasing polarity and the active fraction was determined through the inhibition potency. The inhibition of the active fraction on cell viability, proliferation and colony formation was performed in different AML cells. Induction of apoptosis and the promotion of differentiation were further determined. Then, the level of the reactive oxygen species (ROS) and its potential role were assessed. Finally, anti-AML activity was evaluatapoptosis and differentiation of HL-60 cells was significantly mitigated by NAC. Additionally, C-A-E also exhibited an obvious anti-AML effect in NOD/SCID mice with the injection of HL-60 cells. CONCLUSIONS C-A-E exhibited an inhibitory effect on AML cells by inducing mitochondrial apoptosis and promoting differentiation, both of which were highly correlated to the activation of ROS. The United States lacks a set of unified electronic waste recycling laws, contributing in part to the observed low rate of e-waste recycling behaviors among consumers. Individual factors of consumers contributing to the low recycling rates are not well understood. The objective of this study was to evaluate consumer behaviors, including barriers, surrounding e-waste recycling at a large Midwestern university in the United States. A survey was administered to faculty, graduate students, undergraduate students, and staff to deter
