Extracellular volume and transsarcolemmal proton movement during ischemia and reperfusion: a 31P NMR spectroscopic study of the isovolumic rat heart
(Wiley: NMR in Biomedicine, 1993-07)
We have measured, directly and simultaneously, changes in extracellular volume and intra- and extracellular pH during ischemia in the isolated rat heart using 31P NMR spectroscopy. Hearts were perfused with buffer containing ...
23Na and 39K nuclear magnetic resonance studies of perfused rat hearts. Discrimination of intra- and extracellular ions using a shift reagent
(Biophysical Society: Biophysical Journal, 1985-07)
High-resolution 23Na and 39K nuclear magnetic resonance (NMR) spectra of perfused, beating rat hearts have been obtained in the absence and presence of the downfield shift reagent Dy(TTHA)3- in the perfusing medium. Evidence ...
Aqueous shift reagents for high-resolution cationic nuclear magnetic resonance. III. Dy(TTHA)3−, Tm(TTHA)3−, and Tm(PPP)27−
(Elsevier: Journal of Magnetic Resonance, 1984-01)
The isotropic hyperfine shifts induced in the 23Na+ resonance by the shift reagents Dy(DPA)33−, Dy(NTA)23−, Dy(PPP)27−, Tm(PPP)27−, Dy(TTHA)3−, and Tm(TTHA)3− are compared under similar conditions. The last three are ...
