Paired-ion high-performance liquid chromatographic assay for plasma choline
(Elsevier, 1980-03-14)
Choline was isolated from deproteinized plasma by cation-exchange chromatography. Isolated choline was directly converted to the 3,5-dinitrobenzoate derivative and was analyzed by paired-ion high-performance liquid ...
Agarose drop method for loading thin polyacrylamide gels
(Elsevier, 1982-11-01)
The gels (<1 mm) can be loaded conveniently, rapidly, and quantitatively by suspending the sample to be analyzed in a drop of agarose gel and simply placing the solidified drop on top of the stacking gel. With this ...
Rotational analysis of the red electronic emission spectrum of molybdenum nitride (MoN)
(Elsevier, 1985-04)
A system of emission bands in the red region of the optical spectrum has been identified as due to the species MoN. The system was generated by the microwave (2450 MHz) excitation of a flowing mixture of MoCl5 and molecular ...
Some thoughts on the relations between animal and human drug-taking
(Elsevier, 1983)
1. 1. Results of studies of drug self-administration have frequently been suggested as indicators of the potential for abuse of these drugs by humans. Historical data (pre 1970), although scant, supported this suggestion ...
Thermophysics of metal alkanoates III. Heat capacities and thermodynamic properties of lithium and potassium propanoates
(Elsevier, 1984-01)
At 298.15 K, the values of Cp, m/R, Smo/R, {Hmo - Hmo(0)}/R, and {Gmo - Hmo(0)}/RT ar 15.58, 17.13, 2588.6 K, and -8.445 for CH3CH2CO2Li(cr), and 17.30, 21.16, 3134.0 K, and -10.647 for CH3CH2CO2K(cr). The energetics and ...
Thermal resistivity of layered 4He films on ZYX graphite below 2 K
(Elsevier, 1980-04-01)
Thermal resistance and vapor pressure isotherms were taken near superfluid onset for ultra-thin helium films adsorbed on a ZYX graphite wafer between 1-2 K and 3-7 atomic layers. Our data are consistent with previous ...
Oxygen radicals in complement and neutrophil-mediated acute lung injury
(Elsevier, 1985)
The development of experimental acute lung injury following systemic complement activation is closely related to availability of blood neutrophils. Although tissue-destructive neutrophil-derived may play a supportive role ...
High-dose cisplatin in advanced head and neck cancer
(Springer-Verlag, 1987-04)
In 22 patients with advanced squamous cell carcinoma of the head and neck we evaluated the efficacy and toxicity of 200 mg/m 2 cisplatin administered in 3% NaCl with vigorous hydration. Six patients had previously untreated ...
A simple and rapid method for assessing similarities among directly observable behavioral effects of drugs: PCP-like effects of 2-amino-5-phosphonovalerate in rats
(Springer-Verlag, 1987-09)
Directly observable behavioral effects of the N-methyl- D -aspartate (NMDA) receptor antagonist 2-amino-5-phosphonovalerate (AP5) (10–1,000 mg/kg IP, 0.18–5.6 μmol/rat ICV) and of phencyclidine (PCP) (3.2–56 mg/kg IP, ...
Simple, rapid, and highly efficient separation of amino acid phenylthiohydantoins by reversed-phase high-performance liquid chromatography
(Elsevier, 1982-04)
A rapid and efficient separation of amino acid phenylthiohydantoins by high-performance liquid chromatography has been accomplished by step-gradient elution with use of a mobile phase of acetate-buffered aqueous acetonitrile ...
