Electron mobility variation in dense hydrogen gas
(Elsevier, 1971-08-15)
We present electron mobility measurements in H2 gas for 5 x 1019 21 cm-3 and 26 T < 32[deg]K. The data consist of coexisting high and low mobility branches. The high mobility branch is due to electrons; the low mobility, ...
Studies in molecular structure, symmetry and conformation
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Company Limited ; Springer Science+Business Media, 1971-06)
1-aminocyclohexane carboxylic acid hydrochloride crystallizes in the monoclinic space group P 2 1 with unit cell dimensions a = 9·36, b = 6·40, c = 7·40 Å and β = 96·0 °. The structure has been solved by beta synthesis and ...
Interfacial barriers to the transport of sterols and other organic compounds at the aqueous polysorbate 80-hexadecane interface
(Elsevier, 1971-06-01)
1. 1. The interfacial barrier controlled transport of some biologically important solutes in the aqueous polysorbate 80-hexadecane system were investigated by means of the multiparticulate dispersion technique.2. 2. It was ...
Effect of substrate structure on coupling ratio for Na+-dependent transport of amino acids
(Elsevier, 1971-07-06)
We have measured the coupling ratio, i.e. the ratio of the augmentation of Na+ entry due to the presence of a substrate amino acid, to the augmentation of the entry of that amino acid due to the presence of Na+, for a ...

A comparison of rat and human liver formaldehyde dehydrogenase
(Elsevier, 1971-12-21)
- An NAD- and GSH-dependent formaldehyde dehydrogenase (formaldehyde: NAD+ oxidoreductase, EC 1.2.1.1) was purified from rat and human liver, and the properties of these enzymes were compared. The GSH requirement of the ...
Glycostatic effect of a diabetogenic non-growth-promoting pituitary polypeptide
(Elsevier, 1971-06)
1. 1. Treatment with a mg. of a non-growth-promoting bovine diabetogenic peptide or growth hormone in two divided doses, one at the beginning and one 7-9 hours later, to hypophysectomized rats during a 24-hour fast maintained ...
Enhancement of 3[beta]-hydroxysteroid dehydrogenase-isomerase in the human fetal adrenal by removal of the soluble cell fraction
(Elsevier, 1971-07-20)
To asses whether there is some factor in the soluble cell fraction which might result in inhibition of the 3[beta]-hydroxysteroid dehydrogenase-isomerase enzyme system in the human fetal adrenal, separate homogenate and ...
The Synthesis and Borohydride Reduction of some Alloxazine Derivatives
(WILEY-VCH Verlag GmbH, 1971)
Unequivocal syntheses of N(1 or 3)-mono-substituted 7, 8-dimethylalloxazines are described. The borohydride reduction of various alloxazines has been studied under aerobic and anaerobic conditions, in the absence of light. ...
