Plasma concentrations and urinary excretions of various hormones and hormone metabolites were measured in four groups. Group 1 was composed of 13 men with prior myocardial infarction; Group 2 contained 35 clinically normal men; Group 3 consisted of 44 men with normal coronary arteriograms; and Group 4 was composed of 25 men with severe coronary artery disease shown on arteriogram but no infarct...
De Meio and Lewycka (1) have obtained indirect evidence that conjugation of dehydroisoandrosterone with sulfuric acid occurs in a system consisting of microsome-free supernatant fluid of rat liver, adenosine triphosphate (ATP), and magnesium and sulfate ions. They showed that, following incubation, some of the Zimmermann-positive material remains in the aqueous phase after ether extraction at p...
Two-dimensional J-spectroscopy offers the possibility of a complete separation of chemical shifts and J-couplings. However, the usefulness of the experiment is considerably reduced by the fact that peaks in the spectra have the phase-twist lineshape. We present a simple new spectroscopic method for recording J-spectra in which the peaks are both in the absorption mode and retain their natural i...
