We studied the effects of lanthanum (La3+) on the release of 3H-norepinephrine(3H-NE), intracellular Ca2+ concentration, and voltage clamped Ca2+ and K+ currents in cultured sympathetic neurons. La3+ (0.1 to 10 μm) produced concentration-dependent inhibition of depolarization induced Ca2+ influx and 3H-NE release. La3+ was more potent and more efficacious(More)
A significant proportion of patients with coronary artery disease have symptoms refractory to medical treatment, yet are unsuitable for conventional revascularization techniques, like percutaneous coronary intervention and coronary artery bypass surgery. Such patients are potential candidates for alternative forms of coronary revascularization, like(More)
