Effects of metformin on apoptosis and α-synuclein in a rat model of pentylenetetrazole-induced epilepsy.

abstract：:Small, sinusoidal length changes were superimposed on isometric contractions of fast- and slow-twitch mouse muscles, which were stimulated maximally via their nerves. Stiffness increased with increasing frequency of sinusoidal stimulation, but the relative time course of force and stiffness changes during twitch, teta...
