Phosphate entry into erythrocytes at high levels
(Elsevier, 1962-05-21)
Human red blood cells reach an equilibrium of phosphate distribution at 37[deg] much faster with 0.11 M or intermediate levels than with 0.02 M and lower phosphate levels. Other divalent anions added to 0.02 M phosphate ...
Properties of yeast pyruvate decarboxylase and their modification by proteolytic enzymes : I. Stability of decarboxylases from wild-type and mutant strains
(Elsevier, 1968)
High concentrations of inorganic phosphate and ammonium sulfate stabilize yeast pyruvate decarboxylase to heating at 60 [deg] for long periods of time in the presence of TPP and Mg+. When heated at 60 [deg] in phosphate ...
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 ...
The geologic role of polysulfides--Part II : The solubility of acanthite and covellite in sodium polysulfide solutions
(Elsevier, 1963-12)
The solubility of synthetic low-temperature silver sulfide (acanthite) in solutions of sodium polysulfide of different concentrations, different ratios of sulfur to sulfide and different acidity was determined. The solubility ...
The faradaic admittance of electrochemical processes : III. The frequency dependence
(Elsevier, 1961)
Recent experimental studies have demonstrated the inadequacy of proposed equations for the faradaic admittance, particularly in respect to the frequency dependence. Existing treatments of the faradaic admittance can give ...
A polarographic method for following the rates of cholinesterase-catalyzed hydrolyses of acetylthiocholine
(Elsevier, 1965-08)
A rapid and simple polarographic method for following the rates of the cholinesterase-catalyzed hydrolysis of acetylthiocholine and the rates of inhibition of this hydrolysis is described. This method has the advantage ...
Time and dosage effects of meprobamate on visual detection
(Springer-Verlag, 1964-01)
Sixteen male subjects, 21 years and older, were run in a doubleblind own-control design under three dosages of meprobamate (400, 800 and 1600 mg) and matching placebo, to determine response curves on a visual detection ...
Selenium and tellurium content of stony meteorites by neutron activation
(Elsevier, 1960-04)
By neutron activation analysis the Se- and Te-content of four chondritic meteorites have been determined. The average content is 9.8 +/- 2.5 and 0.61 +/- 1.7 p.p.m., respectively. These values are lower than those already ...
Gas chromatographic separtion of low molecular weight fluorocarbons
(Elsevier, 1968)
Application of gas-solid chromatography techiques to the separation of low molecular weight fluorocarbons incorporates a number of advantages over previous analysis techniques. These advantages include isothermal operation ...
