Calcium influx in skeletal muscle at rest, during activity, and during potassium contracture

CP Bianchi, AM Shanes - The Journal of General Physiology, 1959 - rupress.org
Calcium influx in the sartorius muscle of the frog (Rana pipiens) has been estimated from
the rate of entry of Ca 45 . In the unstimulated preparation it is about equal to what has been …

Calcium flux and contractility in guinea pig atria

S Winegrad, AM Shanes - The Journal of General Physiology, 1962 - rupress.org
… However, as pointed out by Bianchi and Shanes (22), the washout is important to eliminate
the greater variability and reduced sensitivity that would result from the presence of a large …

Anesthetic and calcium action in the voltage clamped squid giant axon

AM Shanes, WH Freygang, H Grundfest… - The Journal of General …, 1959 - rupress.org
Changes in spike configuration and in the inward and outward currents of voltage-clamped
axons agree in indicating that the increases in permeability to sodium and potassium ions …

Drugs and nerve conduction

AM Shanes - Annual Review of Pharmacology, 1963 - annualreviews.org
Propagation of the action potential in nerve fibers is dependent on two related processes-the
electrical excitability of the membrane ahead of the actively depolarized region, and the …

The distribution and kinetics of release of radiocalcium in tendon and skeletal muscle

AM Shanes, CP Bianchi - The Journal of General Physiology, 1959 - rupress.org
The distribution of Ca 45 in frog (Rana pipiens) sartorius muscle, after 4 hours' exposure to
Ringer's solution containing radiocalcium, has been analyzed by observing the kinetics of …

Potassium movement in relation to nerve activity

AM Shanes - The Journal of General Physiology, 1951 - rupress.org
The depolarization of crab nerve during repetitive stimulation is unaffected by the presence
of glucose or by an increase in the calcium content of the medium. It is increased in both …

Radiocalcium release by stimulated and potassium-treated sartorius muscles of the frog

AM Shanes, CP Bianchi - The Journal of General Physiology, 1960 - rupress.org
Stimulation of frog (Rana pipiens) sartorius muscle accelerates release of Ca 45 , but only
during the period of stimulation. No appreciable difference is obtained in the calcium released …
