A method for the separation of glycine-conjugated bile acids as a group from taurine-conjugated bile acids
(Elsevier, 1977-02)
A thin-layer chromatographic method for bile acids has been described which separates glycine conjugates, taurine conjugates, and free bile acids into three separate bands. The solvent system used for this purpose is ...
Androgen receptor protein binding properties and tissue distribution of 2-selena-a-nor-5[alpha]-androstan-17[beta]-ol in the rat
(Elsevier, 1977-07)
2-selena-A-nor-5[alpha]-androstan-17[beta]-ol was studied and in the rat prostate gland. The data demonstrates the ability of this compound to selectively complex with the specific receptors of 5[alpha]-dihydrotestosfcerone ...
Reactions of bis(hexamethylbenzene)iron(0) with carbon monoxide and with unsaturated hydrocarbons
(Elsevier, 1977-02-22)
Thermal decomposition of bis(hexamethylbenzene)iron(0) in the presence of carbon monoxide yields a novel carbonyl iron complex, [C6(CH3)6]Fe(CO)2. The cyclohexadiene complex [C6(CH3)6]Fe(C6H8) is obtained from reaction of ...
Role of proton dissociation in the transport of acidic amino acids by the Ehrlich ascites tumor cells
(Elsevier, 1977-01-21)
The pH profile for the uptake of -glutamic acid by the Ehrlich ascites tumor cell arises largely as a sum of the decline with falling pH of a slow, Na+-dependent uptake by System A, and an increasing uptake by Na+-independent ...
Acidization--VI : On the equilibrium relationships and stoichiometry of reactions in mud acid
(Elsevier, 1977)
A method is presented for determining the distribution of reaction products and the stoichiometric coefficient for the reaction of mud acid (HF/HCl) with various minerals. To illustrate the techniques, the dissolution of ...
An AES study of the surface composition of cobalt ferrites
(Elsevier, 1977-11)
A series of cobalt ferrite samples, Co1-yFe2 + yO4, where -0.1 [les] y [les] 0.1, was examined by AES. A remarkable Fe surface enrichment was observed near the stoichiometric composition for y both positive and negative, ...
Sensitive radioimmunoassay for digoxin in plasma and urine
(Elsevier, 1977-06)
A reproducible and sensitive radioimmunoassay for digoxin in either serum, plasma or urine is described. Using 0.5 ml of serum or plasma, the assay sensitivity is 0.05 ng of digoxin/ml. The antiserum and tracer solutions ...
Plasma prednisolone concentrations: Comparison of radioimmunoassay and competitive protein binding assay
(Elsevier, 1977-05)
A comparison was made between plasma concentrations of prednisolone measured by both competitive protein binding radioassay (CPB) and radioimmunoassay (RIA) and, with each assay, using a calibration curve generated from ...
Molecular structure of n-butane: calculation of vibrational shrinkages and an electron diffraction re-investigation
(Elsevier, 1977-05)
A normal coordinate analysis was carried out based on the force field of Schachtschneider and Snyder in order to calculate all amplitudes of vibration and shrinkage corrections for n-butane. The results are tabulated to ...
