Escape from dexamethasone suppression: Possible role of an impaired inhibitory opioid mechanism
(Elsevier, 1983)
1. 1. Several lines of evidence indicate that the activity of the hypothalamus-pituitary-adrenal (HPA) axis in depression is disinhibited.2. 2. Escape from dexamethasone suppression, although not limited to is more frequent ...
Structure of a water-insoluble -glucan isolated from a streptococcal organism
(Elsevier, 1983-08-16)
The structure of the extracellular polysaccharide (water-insoluble -glucan) from an anaerobic, Gram-positive coccus organism (Streptococcus) has been investigated. Acid hydrolysis of the methylated glucan yielded 2,3,4,6-tetra-, ...
A method to reduce interference by sucrose in the detection of thiobarbituric acid-reactive substances
(Elsevier, 1984-03)
A thiobarbituric acid (TBA) reaction for measuring lipid peroxidation products was evaluated for interference by several ingredients commonly used in solutions to prepare or analyze tissue homogenates or subcellular ...
Characterization of a circular thin film plasma source for atomic emission spectroscopy
(Elsevier, 1985)
A plasma source for analytical atomic emission spectroscopy is described based on the electrical vaporization by capacitive discharge of a thin Ag film deposited on a polycarbonate membrane filter. The source is designed ...
Differences in hydroxysTEROL METABOLISM BETWEEN RAT AND MOUSE LEYDIG CELLS
(Elsevier, 1984-06)
Electroencephalographic assessment of the role of [delta] receptors in opioid peptide - induced seizures
(Elsevier, 1984-12)
DPDPE ([D-Pen2, D-Pen5]-Enkephalin) and DPLPE ([D-Pen2, L-Pen5]-Enkephalin) are conformationally-constrained cyclic analogs of enkephalin with high selectivity for [delta] opioid receptors. Intracerebroventricular (i.c.v.) ...
Strategies for studying opioid peptide regulation at the gene, message and protein levels
(Elsevier, 1984)
Three opioid peptide precursors have been isolated and characterized in endocrine and nervous tissue: pro-opiomelanocortin, pro-enkephalin, and pro-dynorphin. Since each of those opioid peptide systems have been extensively ...
Sensitive high-performance liquid chromatographic assay using 9-fluorenylmethylchloroformate for monitoring controlled-release lidocaine in plasma
(Elsevier, 1989)
A sensitive high-performance liquid chromatographic (HPLC) assay using fluorescence detection for quantifying lidocaine levels in plasma (in the ng/ml range) was developed. This novel HPLC assay has made possible the ...
Contribution of social factors to opiate-induced activation in the mouse
(Elsevier, 1981-04)
Adult male Swiss-Webster mice of varying group size (single, or in groups of 2, 3, or 4) were injected with vehicle, or 25 or 50 mg/kg of morphine sulfate. In comparison with vehicle, morphine-injected mice showed heightened ...
