Inhibition by coenzyme Q of ethanol- and carbon tetrachloride-stimulated lipid peroxidation in vivo and catalyzed by microsomal and mitochondrial systems
(Elsevier, 1988)
The ability of coenzyme Q to inhibit lipid peroxidation in intact animals as well as in mitochondrial, submitochondrial, and microsomal systems has been tested. Rats fed coenzyme Q prior to being treated with carbon ...
Homogeneous enzyme-linked competitive binding assay for riboflavin
(Elsevier, 1988)
A rapid and precise homogeneous enzyme-linked competitive binding assay for riboflavin (vitamin B2) is described. The method utilizes a malate dehydrogenase/3-carboxymethylriboflavin conjugate in conjunction with soluble ...
Structural characterization of the sulfur-capped triangulo cluster, Cp2W2Fe(CO)7(S)
(Elsevier, 1988-09-06)
Cp2W2(CO)4(W[triple bond]) reacts with Fe2(CO)6([mu]-S2) to give Cp2W2Fe(CO)7([mu]3-S) (1) (10%) and Cp2W2Fe2(CO)8([mu]3-S)2 (5%). Spectral properties, cyclic voltammetry, and the structure of 1 are reported. Cluster 1 is ...
Stabilization mechanism of colloidal suspensions by gum tragacanth: The influence of pH on stability
(Elsevier, 1988-11)
An acidic polyelectrolyte, gum tragacanth (GT), was found to stabilize polystyrene latex particles due to a steric stabilization mechanism. The stability depends significantly on the pH of the solution. To elucidate the ...
Effects of Humic Acid on the Adsorption of Tetrachlorobiphenyl by Kaolinite
(American Chemical Society, 1988-12-15)
Humic acids (HA) can affect the partitioning of organic contaminants
between aqueous and sediment phases by complexation in solution
and adsorption of the contaminant-HA complex to a mineral surface.
The objective of ...
Dipole derivatives and infrared intensities of the ester group. An ab initio and force field study of methyl acetate
(Elsevier, 1988-10-31)
Dipole derivatives have been obtained (using both 3-21G and 6-31G basis sets) for methyl acetate. Using a force field refined from experimental data on methyl acetate and its deuterated derivatives, infrared intensities ...
Adenine nucleotide metabolism by isolated kidney tubules during oxygen deprivation
(Elsevier, 1988-06)
Suspensions enriched in isolated rabbit proximal tubules were subjected to varying degrees of oxygen deprivation-induced injury by incubating them under hypoxic conditions at pH 7.4 or pH 6.6 or under high density pelleted ...
Thermodynamics of uranium intermetallic compounds II. Heat capacity of UPd3 from 8 to 850 K
(Elsevier, 1988-07)
The heat capacity (from 8 to 350 K) of UPd3 by adiabatic calorimetry and (from 400 to 900 K) by enthalpy-increment drop calorimetry has been measured and the thermodynamic properties at 298.15 K have been evaluated as ...
Atomic physicochemical parameters for three dimensional structure directed quantitative structure-activity relationships III: Modeling hydrophobic interactions
(John Wiley & Sons, Inc., 1988-01)
In an earlier article 8 the need was demonstrated for atomic physicochemical properties for three dimensional structure directed quantitative structure-activity relationships, and it was shown how atomic parameters can ...
Leukocytes, oxygen radicals, and myocardial injury due to ischemia and reperfusion
(Elsevier, 1988)
Ischemic myocardium generates stimuli for neutrophil chemotaxis before the final extent of irreversible ischemic injury is attained. Reperfusion accelerates the infiltration of ischemic myocardium by neutrophils. Oxygen ...
