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 ...
The direct enhancement of positive palatability by chlordiazepoxide is antagonized by Ro 15-1788 and CGS 8216
(Elsevier, 1987-04)
In a pre previous study, it was found that positive, palatability-dependent consummatory reactions in rats to intraorally infused tastes were facilitated by chlordiazepoxide (10 mg/kg). In contrast, the rats' more neutral ...
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 ...
High levels of non-activated receptors in glucocorticoid-sensitive S49wt mouse lymphoma cells incubated with dexamethasone
(Elsevier, 1994-10)
Upon agonist binding the heteromeric glucocorticoid receptor complex under goes a conformational change (receptor activation). This event involves the dissociation of a dimer of 90 kDa heat shock proteins. Whereas receptor ...
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 ...
Thermodynamics of the monohydrogen difluorides V. Melting thermodynamics of NH4HF2
(Elsevier, 1976-03)
The heat capacity of ammonium hydrogen difluoride was extended from 300 to 450 K by adiabatic calorimetry in order to study the melting phenomenon and provide thermodynamics into the liquid region. The corrected enthalpy ...
A radiation hybrid map of the proximal short arm of the human X chromosome spanning incontinentia pigmenti 1 (IP1) translocation breakpoints
(Elsevier, 1992-11)
Radiation hybrid mapping was used in combination with physical mapping techniques to order and estimate distances between 14 loci in the proximal region of the short arm of the human X chromosome. A panel of radiation ...
Inhibition-mediating dopamine receptors and the control of intracranial reward
(Springer-Verlag, 1979-01)
A receptor selective agonist and antagonist of inhibition-mediating dopamine receptors (type II receptors) produced significant and dose-related alterations in bar-pressing for intracranial reward. Receptor inhibition by ...
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 ...
