Purification of the pancreatic cholecystokinin receptor
(Elsevier, 1989-03)
We have previously shown that the pancreatic cholecystokinin (CCK) receptor can be solubilized in 1% digitonin. In this study, digitonin-solubilized CCK receptors from rat pancreas were purified using sequential affinity ...
Effects of morphine, naltrexone, and dextrorphan in untreated and morphine-treated pigeons
(Springer-Verlag, 1985-03)
Six pigeons, trained to peck a response key on a fixed-ratio 20 schedule of food reinforcement, were used to examine the effects of morphine, naltrexone, and dextrorphan, before, during, and after chronic treatment with ...
Thermophysics of the lanthanide hydroxides I. Heat capacities of La(OH)3, Gd(OH)3, and Eu(OH)3 from near 5 to 350 K. Lattice and Schottky contributions
(Elsevier, 1980-01)
From values of the heat capacity of microcrystalline La(OH)3, Gd(OH)3, and Eu(OH)3 determined by precise adiabatic calorimetry from near 10 to 350 K, the Schottky contribution associated with the low-lying J-manifolds of ...
Detection of electrophoretically silent mutations by immobilized pH gradients
(Elsevier, 1986)
The detection of neutral amino acid mutants, by isoelectric focusing in immobilized pH gradients (IPGs), is exemplified by the separation of hemoglobin (Hb) Beirut (126[beta] Val --> Ala) from Hb A in a shallow pH 7.2-7.6 ...
A total synthesis of the naturally occurring pyrrolo[2,3-]pyrimidine nucleoside, mycalisine A
(Elsevier, 1988)
The first total synthesis of mycalisine A, a pyrrolo[2,3-]pyrimidine nucleoside, was accomplished by a multi-step synthesis from toyocamycin.
Transfer of small plasmid DNA fragments from polyacrylamide gels onto nitrocellulose paper
(Elsevier, 1983-10-15)
The incorporation into a 7% polyacrylamide gel of a nucleic acid-specific photochemical reagent 4,5',8-trimethylpsoralen at a concentration of 1 mg/dl of acrylamide solution improves both the sensitivity and the efficiency ...
Ornithine carbamyl transferase in Reye's syndrome
(Elsevier, 1984-12)
Serum levels of ornithine carbamyl transferase activities were determined in the acutely ill and convalescent Reye's syndrome patients and in their parents. Acutely ill Reye's syndrome patients had elevated levels of serum ...
Comparison of methods of analysis of polychlorinated biphenyls in oils
(Elsevier, 1983)
In order to standardize and validate methods for the analysis of polychlorinated biphenyls in transformer oil, waste oil, hydraulic fluid and capacitor oil in the concentration range 30-500 ppm, a study was performed which ...
