31P Nuclear Magnetic Resonance Spectroscopy of Native and Recombined Lipoproteins

31P nuclear magnetic resonance spectroscopy of native and recombined lipoproteins.

Native and recombined lipoproteins have been studied by (31)P nuclear magnetic resonance spectroscopy. Very low-, low-, and high-density lipoproteins exhibited characteristic spectra. The main resonances were assigned to phosphatidylcholine and sphingomyelin. Relaxation times for these phospholipids were separately measured in low-density lipoproteins and high-density lipoproteins. The effect o...

31P-nuclear magnetic resonance spectroscopy of blood: a species comparison.

31P-nuclear magnetic resonance (NMR) spectroscopy isfrequently used as a tool in the study of organs from various animal species and humans. Because signals arising from the presence of blood are visible in in vivo 31P-NMR spectra of blood-filled organs, such as the heart, it is necessary to correct these spectra for the contribution of blood to the signal. It is unknown whether species differe...

Quantification of plasma lipoproteins by proton nuclear magnetic resonance spectroscopy.

A new analytical procedure for quantifying plasma lipoproteins by proton nuclear magnetic resonance (NMR) spectroscopy has been developed that potentially offers significant advantages over existing clinical methods used for assessing risk of coronary heart disease. Analysis of a single spectrum of a nonfasting plasma sample, acquired simply and rapidly at moderate magnetic field strength (250 ...

31P and 1H Nuclear Magnetic Resonance Spectroscopy of Blood Plasma in Female Patients with Preeclampsia

OBJECTIVE Using (31)P and (1)H magnetic resonance spectroscopy to measure phosphorus- and hydrogen-containing metabolites, this study aimes to investigate whether or not women with preeclampsia have detectable systemic abnormalities concerning certain components of the blood plasma. METHODS PLASMA WAS OBTAINED FROM TWO GROUPS OF WOMEN: Group 1 with preeclampsia (n=10) and Group 2, as a contro...
