β-funaltrexamine antagonizes the discriminative stimulus effects of morphine but not naltrexone in pigeons
(Springer-Verlag, 1987-02)
Antagonistic actions of the irreversible, μ-selective antagonist β-funaltrexamine (β-FNA) were evaluated in pigeons trained to discriminate among intramuscular injections of morphine (5.6 mg/kg), saline, and naltrexone ...
Ion beam modification of metals: Compositional and microstructural changes
(Elsevier, 1989)
Ion implantation has become a highly developed tool for modifying the structure and properties of metals and alloys. In addition to direct implantation, a variety of other ion beam techniques such as ion beam mixing, ion ...
Relationship between the subunit structure of insulin receptor and its competence to bind insulin and undergo phosphorylation
(Elsevier, 1984-11-01)
Insulin receptor partially purified from human placenta by chromatography on immobilized wheat germ agglutinin was subjected to affinity cross linking to determine the relationship between the subunit structure of the ...
Leukotriene C4 induces vasogenic cerebral edema in rats
(Elsevier, 1984-06)
Leukotriene C4 (LTC4) is reported to neither contract nor relax isolated human cerebra artdial strips (1), but in skin LTC4 will increase vascular permeability in post capillary venules, increase blood flow (2) and elicit ...

The endogenous heat-stable glucocorticoid receptor stabilizing factor and the H-2 locus
(Elsevier, 1982-07)
It has recently been suggested that the level of the endogenous glucocorticoid receptor stabilizing factor in mouse liver is regulated by the major hisiocompatibility, H-2. complex (Katsumata et al. [1]). We have developed ...
Interaction of [alpha]2-macroglobulin with trypsin, chymotrypsin, plasmin, and papain
(Elsevier, 1983-02-15)
The interaction [alpha]2-macroglobulin with four proteinases has been investigated by binding assays and by gel electrophoresis. At pH 7.65 the binding ratios of the proteinase-[alpha]2-macroglobulin complexes were found ...
2-Substituted methyl [alpha]--galactopyranosides: Synthesis and binding affinity for the A and B subunits of the Griffonia simplicifolia I isolectins
(Elsevier, 1985-07-01)
The binding affinities of the N-acetyl, N-trifluoroacetyl, N-propionyl, N-formyl, N-benzoyl, N-p-nitrobenzoyl, N-p-aminobenzoyl, and N-methyl derivatives of methyl 2-amino-2-deoxy-[alpha]--galactopyranoside and the 2-O-acetyl, ...
The effects of footshock stress on regional brain dopamine metabolism and pituitary [beta]-endorphin release in rats previously sensitized to amphetamine
(Elsevier, 1987-07)
The repeated intermittent administration of amphetamine (AMP) produces an enduring enhancement in the response of dopamine (DA) systems in the brain to a subsequent "challenge" with amphetamine. However, former amphetamine ...
