The first study that addresses the relationship between microscopic observation for remodeling of surface associated Col IV and it´s dynamic behavior in nano scale finds that cells remodel Col IV in two ways: by mechanical reorganization and via proteolytic degradation.
Ultrastructural evidence for a direct connection between the myocardial granules and the sarcoplasmic reticulum in the cardiac ventricle of Myxine glutinosa (L.)

The core substance of the myocardial granules is shown to be uranophilic and in this respect similar to the granular cores within the lumen of the sarcoplasmic reticulum.

A drop in temperature increased the caffeine-induced Ca release while procaine inhibited it and inhibited the rate of Ca uptake, which may in part account for the prolongation of the active state caused by caffeine.

The effects of caffeine on isometric force development and force-frequency relationships were compared in cat and rat papillary muscle preparations to find out whether caffeine augmented or diminished contractile force in cat muscles, but caffeine depressed contractions under all conditions in rat muscles.

The results suggest that activity of adipose tissue lipase is controlled by the antagonistic activities of the two enzymes, adenyl cyclase and phosphodiesterase, which indicate that the increased lipolysis is mediated through cyclic 39,59-AMP.

It is concluded that velocity active state normally rises rapidly to a constant level which describes the contractile state, and valid time-independent force-peak velocity curves cannot be obtained in the presence of this drug.
