Using solution state NMR spectroscopy to probe NMR invisible gelators.
Supramolecular hydrogels are formed via the self-assembly of gelator molecules upon application of a suitable trigger. The exact nature of this self-assembly process has been widely investigated as a practical understanding is vital for the informed design of these materials. Solution-state NMR spectroscopy is an excellent non-invasive tool to follow the self-assembly of supramolecular hydrogel...
متن کاملNMR-based plasma metabolic profiling in patients with unstable angina
Objective(s): Unstable angina (UA) is a form of the acute coronary syndrome (ACS) that affects more than a third of the population before age 70. Due to the limitations of diagnostic tests, appropriate identification of UA is difficult. In this study, we proceeded to investigate metabolite profiling in UA patients compared with controls to determine potential candidate...
متن کاملQuantitative 1H NMR spectroscopy of blood plasma metabolites.
The absolute quantification of blood plasma metabolites by proton NMR spectroscopy is complicated by the presence of a baseline and broad resonances originating from serum macromolecules and lipoproteins. A method for spectral simplification of proton NMR spectra of blood plasma is presented. Serum macromolecules and metabolites are completely separated by utilizing the large difference in tran...
متن کاملGas-chromatographic measurement of 3-hydroxybutyrate and lactate in plasma and 3-hydroxybutyrate in whole blood.
We describe two simple, rapid, and sensitive gas-chromatographic methods. One is for determining 3-hydroxybutyrate and lactate in plasma, the other for determining 3-hydroxybutyrate in perchloric acid extracts of blood. Samples are purified by adsorption onto graphitized carbon black (Carbopak B). After desorption, the two hydroxyacids are gas-chromatographically measured. Chromatography is on ...
متن کاملThe effect of NMR-invisible susceptibility inclusions on phase maps
Introduction: Phase images generated using GE sequences at high field show exquisite anatomical contrast (1). This results from small changes of the NMR frequency that are linked to variation of the local magnetic susceptibility across tissues. Previous analysis of this phase contrast has generally focused on the effect of the average magnetic susceptibility in a particular compartment (1, 2), ...
