Usually mathematicians use Hodgkin-Huxley model or FitzHug-Nagumo model to simulate action potentials of skeletal muscle fibers. These models are electrically excitable, but skeletal muscle fibers are stimulated chemically. To investigate skeletal muscle fibers we use a model with six ordinary differential equations. This dynamical system is sensitive to initial value of some variables so it is...

background prediction of skeletal growth is necessary for growth modification and surgical orthodontic treatments and is usually done by assessing skeletal maturity indicators in hand-wrist radiographs. the use of growth stages of cervical vertebrae in lateral cephalograms has been suggested to avoid overexposure. objectives this study seeks to assess the degree of agreement between hand-wrist ...

it has been reported that cither lithium or verapamil can potentiate the neuromuscular blocking activity of certain neuromuscular blockers. in the present investigation, possible interaction of verapamil with lithium has been described. the dose ■ response effects of verapamil and lithium on diaphragmatic contractility were assessed in vitro. mechanical responses of the muscle to indirect (nerv...
