Addressing the tradeoff between standard and custom ICs in system level design

Autor: Adams, Jay K., D. E.(Donald E.) Thomas, Carnegie Mellon University.Engineering Design Research Center.

"Digital design at the system level considers the implementation of a system with some mix of standard ICs, custom ICs, and software. In the early stages of design the system is described by a set of descriptions which may include software, hardware

Inhibition by carotid baroreflex of exercise-induced increases in arterial pressure

Autor: D E Donald, S C Walgenbach

Publikováno v: Circulation Research. 52:253-262

Mean arterial blood pressure, heart rate, and cardiac output were measured during continuous graded exercise (5.5 km/hr; 0, 7, 14, and 21% grades) in conscious dogs, under each of the following four conditions: (1) baroreceptors intact, (2) chronic a

Role of vagal afferents in vasodepressor effects of PGE2 in spontaneously hypertensive rats

Autor: D. S. Chen, D. E. Donald, J. C. Romero

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 236:H635-H639

In anesthetized, spontaneously hypertensive rats (Okamoto-Aoki), injections of 0.75, 1.5, and 3.0 microgram/kg PGE2 into the jugular vein caused transient decreases (mean +/- SE) in arterial pressure of 21 +/- 2, 37 +/- 3, and 78 +/- 6 mmHg, respecti

Cardiopulmonary reflexes and arterial pressure during rest and exercise in dogs

Autor: S. C. Walgenbach, D. E. Donald

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 244:H362-H369

Mean arterial blood pressure, heart rate, and cardiac output were monitored at rest and during exercise of two grades of severity in conscious dogs under control conditions and after progressive interruption of the baroreflexes. Aortic arch denervati

Contribution of prostaglandins to muscle blood flow in anesthetized dogs at rest, during exercise, and following inflow occlusion

Autor: O Beaty, D E Donald

Publikováno v: Circulation Research. 44:67-75

The role of locally formed cyclo-oxygenase products (endoperoxide intermediates, prostaglandins, or prostacyclins) in resistance to blood flow was studied in the hindlimbs of anesthetized dogs during rest, during exercise, and following release of in

Maintained ability of carotid baroreflex to regulate arterial pressure during exercise

Autor: A. Melcher, D. E. Donald

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 241:H838-H849

In conscious dogs bilateral carotid occlusion increased arterial pressure by similar amounts at rest (+ 27 mmHg) and during graded exercise (+ 29 mmHg). During exercise stimulus-response curves for arterial pressure and heart rate derived from isolat

Reversible vascular isolation of carotid sinuses in conscious dogs

Autor: R. B. Stephenson, D. E. Donald

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 238:H809-H814

A surgical technique has been developed that permits reversible vascular isolation of both carotid sinuses in the conscious dog. Seven dogs so prepared were studied over periods of 4-12 wk. Repeatable stimulus-response curves relating arterial blood

Reflexes from isolated carotid sinuses of intact and vagotomized conscious dogs

Autor: D. E. Donald, R. B. Stephenson

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 238:H815-H822

Exposure of the vascularly isolated carotid sinuses of 8 conscious dogs to static pressures between 50 and 240 mmHg caused significantly smaller increases [23 +/- 5(SE) mmHg] than decreases (37 +/- 4 mmHg) in arterial pressure frossure and heart rate
