Optimizing phosphorus characterization in animal manures by solution phosphorus-31 nuclear magnetic resonance spectroscopy.
A procedure involving alkaline extraction and solution 31P nuclear magnetic resonance (NMR) spectroscopy was developed and optimized for the characterization of P in animal manures (broiler, swine, beef cattle). Inclusion of ethylenediaminetetraacetic acid (EDTA) in the alkaline extraction solution recovered between 82 and 97% of the total P from the three manures, which represented a significa...
متن کاملPhosphorus 31 Magnetic Resonance Spectroscopy Study
or acutely with verapamil. Left ventricular hypertrophy was induced by suprarenal constriction of the abdominal aorta. Hemodynamics and phosphorus 31 magnetic resonance spectra were monitored simultaneously in the isolated hearts during control perfusion, after 30 minutes of global ischemia, and after 30 minutes of reperfusion. All hypertrophied hearts had significantly higher rate-pressure pro...
متن کاملMetabolic effects of adenosine on regional myocardial ischemia by phosphorus 31 nuclear magnetic resonance spectroscopy.
The metabolic effects of adenosine on regionally ischemic myocardium were investigated in an open-chest rabbit model by means of phosphorus 31 nuclear magnetic resonance (NMR) spectroscopy. Sixteen anesthetized New Zealand white rabbits were subjected to thoracotomy; a reversible snare occluder was placed around a large branch of the left circumflex coronary artery, and an NMR surface coil was ...
متن کاملUrinary excretion of cyclophosphamide in humans, determined by phosphorus-31 nuclear magnetic resonance spectroscopy.
Phosphorus-31 NMR spectroscopy was used to analyze urine samples from patients treated with cyclophosphamide (CP) on 2 consecutive days. CP and all of its known phosphorylated metabolites except the tautomeric pair 4-hydroxycyclophosphamide/aldophosphamide, i.e. carboxycyclophosphamide (CXCP), dechloroethylcyclophosphamide (DCCP), alcophosphamide, ketophosphamide, and phosphoramide mustard (PM)...
متن کاملIdentification of scyllo-Inositol Phosphates in Soil by Solution Phosphorus-31 Nuclear Magnetic Resonance Spectroscopy
A large proportion of the organic P in soils can occur as scylloinositol phosphates. These compounds are rarely detected elsewhere in nature and remain poorly understood, partly because conventional procedures for their determination are lengthy and erroneous. We report a straightforward procedure for the determination of scylloinositol phosphates in soil extracts using solution 31P nuclear mag...
