Nuclear phosphoproteins : I. Isolation and characterization of a phosphoprotein fraction from calf thymus nuclei
(Elsevier, 1969-02-04)
A phosphoprotein fraction has been isolated from calf thymus nuclei which contains about 1.3% alkali-labile phosphorus by wt. The enzymatic reaction in which serine and threonine residues in the protein are phosphorylated ...
Rare earth contribution to the origin of Hawaiian lavas
(Springer-Verlag, 1969-07)
Rare earth abundances were determined by neutron activation in twenty Hawaiian lavas and one diabase of known chemical and mineralogical compositions. These results demonstrate a systematic relationship between the absolute ...
Phosphoproteins from calf-thymus nuclei: Studies on the method of isolation
(Elsevier, 1969-11-11)
Erythrocyte metabolism and function: Hexokinase inhibition by 2,3-diphosphoglycerate and interaction with ATP and Mg2+
(Elsevier, 1969-11-18)
Recent findings have suggested an important role for variation in levels of 2,3-diphosphoglycerate and ATP in the regulation of oxygen transport by the human erythrocyte, and in making homeostatic adjustments to hypoxia. ...
Differential effects of pentobarbital, ethyl alcohol, and chlorpromazine in modifying reticular facilitation of visually evoked responses in the cat
(Elsevier, 1969-01)
Cortical visually evoked responses (VER) elicited by electrical stimulation of the ipsilateral optic tract were dramatically facilitated by stimulation of the midbrain reticular formation. This facilitation depended on the ...
The emission of K-X-rays in slow neutron fission of 233U, 235U, and 239Pu
(Elsevier, 1969-10)
Infrared internal reflectance spectroscopic determination of surface functional groups on carbon
(Elsevier, 1969-09)
An internal reflectance spectrophotometric technique for the direct study of the infrared spectrum of surface functional groups on carbon is presented. The applicability and limitations of this technique are discussed. The ...
Na+ and K+ electrochemical potential gradients and the transport of [alpha]-aminoisobutyric acid in Ehrlich ascites tumor cells
(Elsevier, 1969-11-25)
1. 1. The uptake of [alpha]-aminoisobutyric acid (AIB) was measured in Ehrlich ascites tumor cells which were treated by osmotic shock and cold incubation to elevate cell Na+ and lower K+. These cells were suspended in ...
Analysis of the volatile combustion products of vinyl plastics
(Wiley Subscription Services, Inc., A Wiley Company, 1969-02)
The extensive use of plastics for insulation and building materials has created interest in the possible toxicity of their combustion products. Three poly(vinyl chloride) homopolymers, a vinyl chloride-vinyl acetate ...
