A surface coil is any radiofrequency (RF) coil placed directly on the surface of the subject. Surface coils represent some of the simplest coil designs used in magnetic resonance, but are commonly used in experiments requiring the highest possible sensitivity. In contrast to volume coils, which are designed to provide homogeneous sensitivity over the whole field-of-view, surface coils sacrifice...

The hypothesis that substrate availability can alter contractile function in reperfused myocardium after global ischemia was investigated in this study. Isolated rabbit hearts were placed in a dual tuned C'PI13C) NMR probe with a 9.4-T magnet and perfused with the following substrates given individually or in combination: 10 mM glucose, 2 mM palmitate, and 2.5 mM [3-13C]pyruvate. Glucose was th...

Nearly all atoms contributing to the local structure of Bransted acid sites in zeolites exhibit isotopes accessible for multinuclear solid-state nuclear magnetic resonance (NMR) investigations. Therefore, in the last 15 years, NMR spectroscopy has found numerous applications for the determination of the types of hydroxyl proton in zeolites, of their concentration, accessibility, and mobility, a...

Ssu72 helps regulate transcription and cotranscriptional mRNA processing by dephosphorylating serine residues at the 5th position in the heptad repeats of the C-terminal domain of RNA polymerase II. Here we use multidimensional, multinuclear NMR experiments to assign the backbone and side-chain resonances of the 23 kDa Ssu72 from Drosophila melanogaster in the phosphate-bound state, and use NMR...

Abstract A new multistage synthesis of the N-borylated dipeptide B 12 -PheGlyOH has been proposed. The approach is based on reaction nucleophilic addition amino acid derivatives to [B H 11 NCCH 3 ] – anion. products each stage have characterized by multinuclear NMR spectroscopy, IR absorption and ESI mass spectrometry.
