Purpose To study limb immobilization influencing on denervated muscle atrophy.

This paper reviews two main signaling pathways in order to introduce the key role of Akt in it,one is Akt1/FOXOs/MAFbx/MuRF1 signaling path- way which associated with muscle atrophy;the other is PI3K/Akt/mTOR/S6K1 signaling pathway which associated with muscle hypertrophy.

Methods: In order to establish the cell model of using GCs to cause the muscle atrophy,we examined the total protein of the C2C12 muscle tube which was fed with Dexamethasone(DEX,100 nMs) for 1 to 4 days using BCA method.

Pharmacology of Shen Feng Jing Ⅱ.Effects of Shen Feng Jing on nerve conduction and muscle contraction of Indian bullfrog;

According to swinging cross bridge model,muscle contraction is produced by cyclical attachment and detachment of cross bridges towards thin filament.

ATP is the direct energy and plays a key role in the process of muscle contraction.

Methods: Eighteen rats were randomly divided into 3 groups:control group,muscular atrophy group and intervention group.

muscular contraction, action potential, electromyogram, tetanus, supra compensation and plateau training.

this paper researches very systematically the biomechanical characteristics of skeletal muscles in three aspects including the theory of muscle working; the characteristics of muscular contraction and muscular structures.

Many active processes in biological systems such as muscular contraction, cell motility and some cellular transport processes are mediated by biological molecules.
