Heat capacities of bis-tetraethylammonium tetrachloronickelate and tetrachlorozincate I. Structural transitions and thermophysical results
(Elsevier, 1979-03)
The heat capacities of bis-tetraethylammonium tetrachloronickelate () and tetrachlorozincate () were measured over the temperature range 5 to 350 K by adiabatic calorimetry. Bifurcated anomalies were found for both compounds ...
Biosynthesis of keratan sulfate: Purification and properties of a galactosyltransferase from bovine cornea
(Elsevier, 1979-02)
A soluble galactosyltransferase was purified 22,000-fold from bovine cornea. The enzyme catalyzes the transfer of galactose from UDP-galactose to N-acetyl--glucosamine, [alpha]- and [beta]-glucosaminides, bovine cornea and ...
Studies on the turnover of proteins of the rat erythrocyte membrane
(Elsevier, 1979-10-19)
The membrane proteins of erythrocytes were labeled by injecting -[14C]leucine and later -[3H]leucine into rats, the two injections being 31 days apart. Control animals received the two isotopic forms of -leucine simultaneously. ...
Cross-peptide bond 13C---15N coupling constants by 13C and J cross-polarization 15N NMR
(Elsevier, 1979-07)
Comparative 13C---15N coupling constants are reported for the linear dipeptide tBoc--[U-13C]Ala-[15N]GlyOMe and the corresponding cyclic diketopiperazine, both in dimethylsulfoxide (DMSO) and, upon removal of the tBoc ...
Low-temperature phase transitions of Fe3O4 with innocuous dopants
(Elsevier, 1979-04)
Both Zn2+ and Cd2+ dopants on the A-sites in Fe3O4 lead to a loss in the furcation of the lambda anomaly at the Verwey transition but at markedly different dopant levels. Equilibrium adiabatic calorimetry from 5 to 350 K ...
The protective effects of dietary fish oil on focal cerebral infarction
(Elsevier, 1979-11)
The protective effect of the (n-3) fatty acids in menhaden fish oil on acute cerebral ischemia was investigated in cats. Cerebral ischemia was produced by ligation of the left middle cerebral artery of cats fed either a ...
Purification of RNA polymerase from actinomycin producing and nonproducing cells of Streptomyces antibioticus
(Elsevier, 1979-11)
DNA-dependent RNA polymerase has been purified approximately 700-fold from 12-h-old cells of Streptomyces antibioticus and 400-fold from 48-h cells. Both enzymes appear nearly homogeneous as judged by sodium dodecyl ...
Direct thermomagnetic splitting of water
(Elsevier, 1979)
The application of a magnetic field to water tends to cause its decomposition into hydrogen and oxygen. Based upon the thermomagnetochemistry of the phenomenon, a process is suggested for carrying out the reaction and ...
A high affinity site for sugar transport at the inner face of the human erythrocyte membrane?
(Elsevier, 1979-08-07)
A disagreement centering on a method of analysis as to the existence of a high affintiy site for glucose transport at the inner face of the human red cell membrane is resolved by using direct fitting methods to confirm the ...
Deprotonation studies in [alpha]-oxoketene dithioacetals. I.
(Elsevier, 1979)
Deprotonations of [alpha]-benzoyl ketene dithiomethylacetals with LDA/HMPA resulted in kinetic deprotonations at three different sites depending on the other [alpha]-substituents.
