(噬菌体)可收缩尾;
METHODS: Isometric twitch and high-frequency tetanic contraction were examined by perfusion technique of isolated skeletal muscle strip. The contractile functions of soleus were observed in 1-week, 2-week, or 4-week tail-suspended rats.
方法:采用离体骨骼肌条灌流技术,观测模拟失重1,2和4wk大鼠比目鱼肌(SOL)等长收缩的阈刺激电压与高频强直收缩功能的动态变化。
the contractile tail of bacteriophage t4 undergoes major structural transitions when the virus attaches to the host cell surface.
