Autor: F C, Garcia, V M, Stiffel, W J, Pearce, L, Zhang, R D, Gilbert

Publikováno v: Journal of the Society for Gynecologic Investigation. 7:161-166

To determine the contribution of decreased calcium responsiveness of fetal coronary arteries to decreased contractile responses to potassium and the thromboxane A(2) analogue U46619 in these arteries after exposure to chronic hypoxemia.Concentration-

Possible Functional Linkage Between the Cardiac Dihydropyridine and Ryanodine Receptor: Acceleration of Rest Decay by Bay K 8644

Autor: Eileen McCall, Donald M. Bers, V. M. Stiffel, D. M. Christensen, L. V. Hryshko

Publikováno v: Journal of Molecular and Cellular Cardiology. 28:79-93

The effect of the dihydropyridine L-Type Ca chanel agonist Bay K 8644 on post-rest contractions in ferret ventricular muscle and isolated myocytes was investigated. Bay K 8644 was shown to abolish rest potentiation and greatly accelerate rest decay.

Effects of long-term high-altitude hypoxia on isolated fetal ovine coronary arteries

Autor: F C, Garcia, V M, Stiffel, R D, Gilbert

Publikováno v: Journal of the Society for Gynecologic Investigation. 7(4)

To examine the effects of long-term high-altitude hypoxia on the contractile properties of isolated fetal coronary arteries.Maximal contractile responses (T(max)) to 90 mmol/L KCl and the thromboxane A(2) mimetic U46619 were measured in proximal (PLC

Ratio of ryanodine to dihydropyridine receptors in cardiac and skeletal muscle and implications for E-C coupling

Autor: Donald M. Bers, V. M. Stiffel

Publikováno v: The American journal of physiology. 264(6 Pt 1)

We measured dihydropyridine receptor (DHPR) and ryanodine receptor (RYR) density in isolated ventricular myocytes from rabbits, rats, ferrets, and guinea pigs and also from rabbit ventricular homogenate, skeletal muscle homogenate, and isolated triad
