Regulation of oxygen delivery during induced polycythemia in exercising dogs

Autor: Victoria L. Travis, John V. Weil, Lawrence D. Horwitz, JoAnn Lindenfeld

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 289:H1821-H1825

Previous studies have concluded that polycythemia decreases oxygen delivery primarily because of a large fall in cardiac output associated with a rise in systemic vascular resistance that has been attributed to increased blood viscosity. However, bec

Plasma catecholamine responses to exercise after training with beta-adrenergic blockade

Autor: Eugene E. Wolfel, Victoria L. Travis, H L Brammell, Lawrence D. Horwitz, William R. Hiatt

Publikováno v: Journal of Applied Physiology. 68:586-593

Exercise training has been shown to decrease plasma norepinephrine (NE) and epinephrine (EPI) levels during absolute levels of submaximal exercise, which may reflect alterations in sympathetic tone as a result of training. To determine if beta-adrene

Effects of selective and nonselective beta-adrenergic blockade on mechanisms of exercise conditioning

Autor: Eugene E. Wolfel, M R Carry, Victoria L. Travis, William R. Hiatt, Steven P. Ringel, Lawrence D. Horwitz, H L Brammell

Publikováno v: Circulation. 74:664-674

Exercise conditioning involves adaptations in the heart, peripheral circulation, and trained skeletal muscle that result in improved exercise capacity. Since the specific influence of beta-adrenergic stimulation on these various adaptations has not b

Low Serum Dopamine β-Hydroxylase Activity

Autor: Victoria L. Travis, Lawrence D. Horwitz

Publikováno v: Journal of Clinical Investigation. 62:899-906

To gain information about the nature of disturbances in sympathetic nervous system control in congestive heart failure, serum dopamine beta-hydroxylase (DBH) activity was measured in 30 patients with heart failure of diverse etiologies and 29 healthy

The Effect of Platelet Protein and Dna on the Measurement of Human Lymphocyte Beta Adrenergic Receptor Number

Autor: Kathryn B. Horwitz, William R. Hiatt, Victoria L. Travis, Lawrence D. Horwitz

Publikováno v: Journal of Receptor Research. 5:419-429

Considerable variation exists in human lymphocyte beta adrenergic receptor measurements when the data are reported as fmole/mg protein. To investigate potential sources of measurement errors, human lymphocytes were prepared as follows: With the stand
