Nakamura M, Thourani V, Ronson R, Velez D, Ma X, Katzmark S, et al.
Circulation . 2000 Nov; 102(19 Suppl 3):III332-8. PMID: 11082410
Background: NO has been advocated as an adjunct to cardioplegia solutions. However, NO undergoes a rapid biradical reaction with superoxide anions to produce peroxynitrite (ONOO(-)). ONOO(-) in crystalloid cardioplegia solution...

Nakamura M, Toombs C, Duarte I, Ronson R, Schmarkey L, Katzmark S, et al.
Ann Thorac Surg . 1998 Nov; 66(4):1216-23. PMID: 9800809
Background: Cardiopulmonary bypass contributes to platelet loss and dysfunction by exposure to shear stresses, foreign surfaces, and hypothermia. This study tested the hypothesis that pegylated recombinant human megakaryocyte growth and...

Eisner R, Schmarkey L, Martin S, Carey D, Worthy M, Chu T, et al.
J Nucl Med . 1994 Apr; 35(4):638-43. PMID: 8151388
Unlabelled: Technetium-99m-sestamibi images reflect tracer distribution at the time of injection. This "stay put" indicator allowed us to separate the effects of segmental left ventricular dysfunction per se versus myocardial...

Martin S, Schmarkey L, Oh D, Patterson R
Cardiovasc Res . 1993 Nov; 27(11):2028-36. PMID: 8287414
Objectives: Whether intracoronary papaverine or adenosine leads to reductions in regional left ventricular function was tested. Methods: Fifteen anaesthetised dogs were prepared to record aortic pressure, left ventricular pressure dP/dt,...

Martin S, Lenhard S, Schmarkey L, Offenbacher S, Odle B
Am J Physiol . 1993 May; 264(5 Pt 2):H1438-46. PMID: 8498558
Adenosine may mediate coronary vasodilation during work-related hyperemia and during ischemia. We tested whether adenosine blockade with 8-p-sulfophenyltheophylline (PSPT) prevented dobutamine-induced hyperemia or magnified the reductions in flow due to...

Eisner R, Martin S, Leon A, Schmarkey L, Worthy M, Chu T, et al.
J Nucl Med . 1993 Feb; 34(2):281-7. PMID: 8429348
By computer simulation, we have previously hypothesized, independent of the isotope imaged, that differences in view-to-view resolution and attenuation patterns predictably cause count density distortions in SPECT images. We tested...

Leon A, Eisner R, Martin S, Schmarkey L, Aaron A, Boyers A, et al.
J Am Coll Cardiol . 1992 Dec; 20(7):1612-25. PMID: 1452936
Objectives: The purpose of the present study was to compare single-photon emission computed tomographic (SPECT) myocardial images of technetium-99m (Tc-99m) sestamibi and thallium-201 (Tl-201) isotopes in the same dog undergoing...
