1.
Prakash R, Grood E, Mates R
J Biomech Eng . 2013 May; 99(1):9-13. PMID: 23720200
A five-parameter transfer function has been used to characterize the input impedance of the human systemic circulation. Aortic pressure and flow measurements obtained at cardiac catheterization are employed to evaluate...

Edsberg L, Mates R, Baier R, LAUREN M
J Rehabil Res Dev . 2000 Feb; 36(2):133-41. PMID: 10661529
Several hypotheses exist for the etiology of decubitus ulcers, with external pressures exceeding internal capillary pressures over bony prominences claimed to be the major factor. This investigation evaluated the mechanical...

Mates R
J Biomech Eng . 1993 Nov; 115(4B):558-61. PMID: 8302041
Dramatic advances have been made in the last two decades in the diagnosis and treatment of coronary artery disease. The development of open heart surgical techniques for bypassing occluded arteries...

Mates R, Judd R
Adv Exp Med Biol . 1993 Jan; 346:153-61. PMID: 8184753
We have developed a mathematical model which describes pressure-inflow relationships in the coronary circulation. Model parameters have been identified during metabolic and pharmacologic vasodilation. These two stimuli appear to affect...

Judd R, Mates R
Am J Physiol . 1991 Jun; 260(6 Pt 2):H1841-51. PMID: 2058721
Although it is well known that coronary inflow decreases substantially during systole, the mechanism responsible for this decrease remains controversial. Knowledge of how coronary input impedance is affected by contraction...

Judd R, Redberg D, Mates R
Am J Physiol . 1991 Mar; 260(3 Pt 2):H943-52. PMID: 2000989
Systolic myocardial contraction may produce changes in coronary resistance and capacitance that persist throughout a normal diastole. In addition, coronary resistance and capacitance as determined in the arrested heart may...

Farhi E, Klocke F, Mates R, Kumar K, Judd R, Canty Jr J, et al.
Circ Res . 1991 Feb; 68(2):392-401. PMID: 1991345
We examined the "vascular waterfall" hypothesis, which proposes that coronary flow is unaffected by elevations in outflow pressure until the latter reaches a critical threshold level, in 29 isolated canine...

Prog Cardiovasc Dis . 1988 Jul; 31(1):1-15. PMID: 3293117

Canty Jr J, Klocke F, Mates R
Circ Res . 1987 Feb; 60(2):273-82. PMID: 3568296
Although previous studies have proposed a variety of models to characterize diastolic pressure-flow relations, the models' ability to predict capacitance-free pressure-flow relations from dynamic information in individual studies has not...

Canty Jr J, Klocke F, Mates R
Am J Physiol . 1985 May; 248(5 Pt 2):H700-11. PMID: 3993808
To quantify reactive elements of the coronary circulation, we have characterized in vivo diastolic coronary input impedance by introducing sinusoidal pressure oscillations of constant amplitude and varying frequency at constant...
