The effects of the NMR shift-reagents Dy(PPP)2, Dy(TTHA) and Tm(DOTP) on developed pressure in isolated perfused rat hearts. The role of shift-reagent calcium complexes.
J. Mol. Cell. Cardiol. 33(11) , 1945-56, (2001) The 23Na NMR shift-reagent complexes (Dy(PPP)2, Dy(TTHA), and Tm(DOTP)) bind stoichiometric amounts of Ca2+. Thus, in perfused rat heart systems, a supplementation of Ca2+ is required to maintain the requisite extracellular free calcium concentration ([Ca(o)]... |

Ischemic changes in myocardial ionic contents of the isolated perfused rat hearts as studied by NMR.
Mol. Cell Biochem. 119(1-2) , 109-20, (1993) Using 31P-, 23Na- and 39K-NMR, we assessed ischemic changes in high energy phosphates and ion contents of isolated perfused rat hearts continuously and systematically. To discriminate intra- and extracellular Na+, a shift reagent (Dy(TTHA)3-) was used in 23Na... |
