Isolation of a cDNA coding for human galactosyltransferase
(Elsevier, 1986-08-29)
Human milk galactosyltransferase (EC 2.4.1.22) was purified to homogeneity using affinity chromatography. Edman degradation was used to determine the amino acid sequences of eight peptide fragments isolated from the purified ...
Evidence for coupling of the [kappa] opioid receptor to brain GTPase
(Elsevier, 1986-11-10)
In membranes from guinea pig cerebellum, a tissue which predominantly contains [kappa] opioid receptors, exogenous and endogenous [kappa]-selective opioid agonists stimulated low-Km GTPase activity by 11-20% with concentrations ...
Tumor necrosis factor stimulates interleukin-1 and prostaglandin E2 production in resting macrophages
(Elsevier, 1986-04-14)
We have investigated the effect of tumor necrosis factor on the release of interleukin-1 and PGE2 from murine resident peritoneal macrophages. Tumor necrosis factor causes an increase in the production of interleukin-1 and ...
Conversion of leukotrienes A4 to C4 in cell-free systems
(Elsevier, 1986-01-14)
A procedure for assaying leukotriene C4 synthase activity in cell-free extracts has been presented. Leukotriene A4 methyl ester was as active a substrate as leukotriene A4 (Na salt) for the synthesis. The methyl ester is ...
Analysis of the mitochondrial and nuclear genomes of two basidiomycetes, Coprinus cinereus and Coprinus stercorarius
(Springer-Verlag, 1986-03)
The mitochondrial and nuclear genomes of Coprinus stercorarius and C. cinereus were compared to assess their evolutionary relatedness and to characterize at the molecular level changes that have occurred since they diverged ...
Cation-diffusion-induced characteristic beam damage in transmission electron microscope images of micas
(Elsevier, 1986)
Transmission and analytical electron microscopy have been used to characterize the numerous lenticular fissures which were observed in electron micrographs of paragonite. Observations with a very weak electron beam revealed ...
Estimation of the affinity of naloxone at supraspinal and spinal opioid receptors in vivo: Studies with receptor selective agonists
(Elsevier, 1986-11-10)
The apparent affinity of naloxone at cerebral and spinal sites was estimated using selective mu [D-Ala2, Gly-ol5]-enkephalin (DAGO) and delta [D-Pen2, D-Pen5]enkephalin] (DPDPE) opioid agonists in the mouse warm water ...
Time budgets of grassland herbivores: body size similarities
(Springer-Verlag, 1986-08)
The summer (May–September) time budgets of 14 generalist herbivore species living in the same grassland environment are presented in terms of various component activities (e.g., walking, feeding, resting, etc.). All the ...
The transformation of Saperda calcarata (Coleoptera: Cerambycidae) into a cellulose digester through the inclusion of fungal enzymes in its diet
(Springer-Verlag, 1986-12)
The larvae of the aspen borer, Saperda calcarata , which feed on the inner bark and sapwood of living aspen stems, are unable to digest cellulose. However, they can be transformed into cellulose digesters by adding the ...
Identification of gonadotropin inducible, high density lipoprotein receptors in the solubilized membranes from rat ovary
(Elsevier, 1986-01-29)
Specific receptors for high density lipoproteins (HDL3) were solubilized from membranes of rat corpus luteum using different detergents. Among the detergents tested, octyl-[beta]-D-glucoside (40 mM) was most effective with ...
