[Objective] To observe the role of low concentration horse serum on differentiation inducement of C2C12 myoblasts into mature myocytes and consequent formation of myotubes, exploring a method for committed myogenic differentiation, and its related molecular mechanisms.

Objective To study the effect of dexamethasone on degradation of longlived protein in myotubes and to elucidate its possible mechanism.

The effect of removal of external Ca 2+ on phosphoinositide hydrolysis was investigated in cultured myotubes from 9 day old Leghorn embryonic chicken.

Effects of dexamethasone on the gene expression of ubiquitin system in cultured myotubules;

Results: The entrance and exit of supinator tunnel were composed of tendinous tissues.

We use the nonlinear feedback synchronization control to study the synchronous problem on the biomathematical model of muscular blood vessel,using the error signal of the master system and the slave system and adding the feedback control to design a nonlinear feedback controller with a single variable,making the slave system follow the tracks of the master system,i.

The approximation solutions are given to the biomathematical model of muscular blood vessel under two cases.

By using the fixed points theorem of twist map, the author proves that the biomathematical model of muscular blood vessel: x+B+Ax+γx 3=E cos ωt has at least one 2π /ω periodic solution under condition: B/2<1 where A, B, γ, E, ω are positive constant.
