NUCLEAR MAGNETIC RESONANCE STUDY OF THE STRUCTURE OF GLYOXALDIHYDRAZONE
Study of the nuclear magnetic resonance spectra of glyoxaldihydrazone in dimethylsulfoxide and deuterochlorofonn leads to the conclusion that this compound exists predominantly in non-chelate structure
متن کامل23Na nuclear magnetic resonance study of Na+-K+ pump inhibition by a fraction from uremic toxins.
An in vitro inhibitor of Na+/K+-transporting ATPase (EC 3.6.1.37) was isolated from uremic plasma and normal urine by liquid chromatography. A 23Na nuclear magnetic resonance study involving living erythrocytes showed that this inhibitor causes impairment of the Na+-K+ pump of intact erythrocytes. This finding may explain the high intra-erythrocytic sodium concentration in those uremic patients...
متن کاملMeasurement of intracellular sodium concentration and sodium transport in Escherichia coli by 23Na nuclear magnetic resonance.
Escherichia coli is known to actively extrude sodium ions, but little is known concerning the concentration gradient it can develop. We report here simultaneous measurements, by 23Na NMR, of intracellular and extracellular Na+ concentrations of E. coli cells before and after energization. 23Na spectra in the presence of a paramagnetic shift reagent (dysprosium tripolyphosphate) consisted of two...
متن کاملQuantitative assessment of muscle injury by 23Na magnetic resonance imaging
BACKGROUND (23)Na magnetic resonance imaging ((23)Na-MRI) is able to measure Na(+) in vivo in humans and allows quantification of tissue sodium distribution. We now tested the utility of (23)Na-MRI technique in detecting and assessing sports-related acute muscular injury. CASE PRESENTATION We assessed tissue Na(+) of both lower legs with a 3T MRI scanner using a customized (23)Na knee coil. T...
متن کامل23Na magnetic resonance imaging-determined tissue sodium in healthy subjects and hypertensive patients.
High dietary salt intake is associated with hypertension; the prevalence of salt-sensitive hypertension increases with age. We hypothesized that tissue Na(+) might accumulate in hypertensive patients and that aging might be accompanied by Na(+) deposition in tissue. We implemented (23)Na magnetic resonance imaging to measure Na(+) content of soft tissues in vivo earlier, but had not studied ess...
