Introduction: The rapid development of wireless telecommunication technologies over the past decades, has led to significant changes in the exposure of the general public to electromagnetic fields. Nowadays, people are continuously exposed to different sources of electromagnetic fields such as mobile phones, mobile base stations, cordless phones, Wi-Fi routers, and power lines. Therefore, th...

INTRODUCTION The magnitude of the neural activation, and hence the force produced by a muscle, depend on the number of motor units activated (recruitment) and the rates at which motor neurons discharge action potentials (rate coding). Although the recruitment order of motor units (size principle) is similar for contractions during which the force is gradually increased (ramp contraction) and th...

Objective: To investigate the effects of isradipine, which is a calcium channel blocker, on late pregnant rats’ myometrium under in vitro conditions. Methods: Stripes were obtained from the myometriums of pregnant rats which were decapitated on the 18 days of gestation. The effects of isradipine on myometrium were investigated in four groups and four cumulative doses: 1 ng/ml, 10 ng/ml, 0.1 μg/...
