To investigate how a back propagation neural network based on genetic algorithm (GA-BPNN) optimizes the low-intensity pulsed ultrasound (LIPUS) stimulation parameters to improve bone marrow mesenchymal stem cells (BMSCs) viability further. The LIPUS were set at various frequencies (0.6, 0.8, 1.0, and 1.2 MHz), voltages (5, 6, 7, 8 V), durations (3, 9 minutes). As only some discrete points can be up in experiments, optimal parameter may not value of these settings. GA-BPNN is used optimize...
Objective To explore the curative effect of autologous activated Schwann cells (AASCs) in rat spinal cord injury (SCI) via different grafting routes. Methods Saphenous nerve adult Wistar was ligated for one week to activate cells. And then AASCs were cultured, passaged, purified and identified vitro. Sixty rats all made into SCI model at T10 divided three groups randomly. One after injury, transplanted routes [group Ⅰ: tail vein; group Ⅱ: intrathecal (subarachnoid route); Ⅲ: intraspinal...
