Purpose Human umbilical endothelial cells (HUVECs) have been proved as an effective whole-cell vaccine inhibiting tumor angiogenesis. However, HUVECs divide a very limited number of passages before entering replicative senescence, which limits its application for clinical situation. Here, we fused HUVECs with human pulmonary adenocarcinoma cell line A549s and investigated the anti-tumor immunity of...
Synch recording and simulation of motion has many appLication realms. It is of certain significance to study it systematically. Based on a set of existing hydrauLic servo driven 3-DOF(Degree Of Freedom) synchronous on-Line recorder and simulator, The motion measure algorithm is deduced. the adaptive BP-PID controller is designed accordingly. The experiment is carried out also and the results prove...
