Enkephalinase: Selective inhibitors and partial characterization
(Elsevier, 1980)
There are at least two types of enzymes in brain, endopeptidases and aminopeptidases, which metabolize enkephalins. Evidence is presented to suggest that enkephalinase, an endopeptidase cleaving at the Gly-Phe bond, is ...
A convenient synthesis of substituted [gamma]-pyrones
(Elsevier, 1980)
An efficient and general synthetic method for various 2-mono- and 2,6-disubstituted [gamma]-pyrones has been developed. This utilizes the -acylation (70-85%) of [beta]-methoxy-[alpha],[beta]-enone lithium enolates by acid ...
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 ...
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 ...
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 ...
Lithium and the structure of exploratory behavior in the rat
(Elsevier, 1980)
1. 1. Adult male Sprague Dawley rats were given lithium as a dietary supplement, or a control diet.2. 2. A single seven hour test of exploratory behavior was carried out after one week of chronic drug exposure.3. 3. The ...
A solid support for affinity chromatography that covalently binds thiol groups via a cleavable connector arm
(Elsevier, 1980-09)
Preparation of an agarose derivative (MPE-agarose) containing a maleimido group which is attached to agarose via a cleavable phenyl ester linkage is described. MPE-agarose was shown to react with the thiol groups in ...
Grooming elicited by intracerebroventricular bombesin and eledoisim in the mouse
(Elsevier, 1980-01)
The behavioral effects of centrally administered bombesin and eledolsin were investigated in the mouse. Both peptides produced syndromes of compulsive stereotyped grooming. Manipulations known to affect other forms of ...
The effects of ethanol, phenobarbital, and baclofen on ethanol withdrawal in the rhesus monkey
(Springer-Verlag, 1980-10)
Physical dependence on ethanol was produced in four rhesus monkeys by IV ethanol administration every 8 h. Ethanol was administered on each occasion until the eyeblink reflex was lost. Evidence of physical dependence ...
Mechanisms of gentamicin-induced dysfunction of renal cortical mitochondria : II. Effects on mitochondrial monovalent cation transport
(Elsevier, 1980-11)
Mitochondrial swelling techniques were used to evaluate the effects of the aminoglycoside antibiotic gentamicin on renal cortical mitochondrial monovalent cation permeability. Gentamicin behaved like EDTA to enhance ...
