DR4 can transmit apoptosis signal initiated by Apo2L/TRAIL (TNF-related apoptosis inducing ligand). It can activate caspases within seconds of ligand binding and cause an apoptotic demise of the cell within hours. Despite several investigations, the mechanisms of apoptosis initiation by Apo2L/TRAIL remain unclear.展开更多

This article had discussed the influence of coating properties, technologies of heating and pressure etc. on ink absorption and showed that ink absorption can be adjusted and coating surface structure can be improved when technologies of heating and pressure change, pigment and adhesive altered.展开更多
