P-31 MR spectroscopy of normal human brain and brain tumors.
TL;DR: The metabolite concentrations and pH in human brain tumors differ significantly from those in normal brain, and these differences may be ultimately useful in characterizing tumors in man.

Noninvasive quantitation of phosphorus metabolites in human tissue by NMR spectroscopy
Klaus Roth,B. Hubesch,Dieter J. Meyerhoff,S. Naruse,J. R. Gober,T. J. Lawry,Michael D. Boska,Gerald B. Matson,M. W. Weiner +8 more
TL;DR: In this article, an external reference of hexamethyl phosphoroustriamide was used to quantify metabolite concentrations using 31 P NMR spectroscopy, and the method was applied to seven normal human subjects.

In-vivo analysis of epicutaneous pressure distribution beneath a femoral tourniquet – an observational study
Klaus Roth,Boris Mandryka,Gerrit Steffen Maier,Uwe Maus,Manfred Berres,Jan-Dirk Rompe,Friedrich Bodem +6 more
TL;DR: The measurement series revealed a global pressure drop compared to the initial pressure of the cuff, and no relationship could be demonstrated between the pressure transferred to the skin and the BMI or limb circumference.

Phosphorus-31 magnetic resonance spectroscopy in humans by spectroscopic imaging: localized spectroscopy and metabolite imaging
D. B. Twieg,Dieter J. Meyerhoff,B. Hubesch,Klaus Roth,D. Sappey-Marinier,M. D. Boska,J. R. Gober,Saul Schaefer,M. W. Weiner +8 more
TL;DR: In this article, a linear predictor technique was used to estimate the initial points of the free induction decay missing because of the delay needed for phase-encoding gradients, significantly reducing the baseline artifacts which commonly complicate interpretation of SI spectra.

Determination of cytosolic ADP and AMP concentrations and the free energy of ATP hydrolysis in human muscle and brain tissues with 31P NMR spectroscopy
TL;DR: Based on experimentally determined concentrations of PCr, Pi, ATP, and H+, the ADP and AMP concentrations and the free energy for the ATP hydrolysis in normal human brain and muscle were calculated assuming that the creatine kinase‐ and the myokinase‐catalyzed reactions were in equilibrium.
