Discriminative and aversive properties of [beta]-carboline-3-carboxylic acid ethyl ester, a benzodiazepine receptor inverse agonist, in rhesus monkey
(Elsevier, 1986-03-17)
Rhesus monkeys were trained to discriminate injections of saline from those of [beta]-carboline-3-carboxylic acid ethyl ester ([beta]-CCE), a compound that binds to the benzodiazepine receptor, but often has actions opposite ...
Ontogenesis of corticotropes and lactotropes in situ in the pituitary gland of the hamster
(Springer-Verlag, 1986-09)
The development of corticotropes and lactotropes was investigated in the golden Syrian hamster using an anti-porcine ACTH antiserum and a homologous antihamster PRL antiserum. Oval corticotropes were first visible in the ...
Equivalence between S-systems and Volterra systems
(Elsevier, 1986-03)
S-systems and Volterra systems have been developed independently of each other in different branches of biology. We show that these systems are mathematically equivalent.
Amino acid sequence of the active site of human serum cholinesterase from usual, atypical, and atypical-silent genotypes
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1986-06)
Active-site tryptic peptides were isolated from three genetic types of human serum cholinesterase. The active-site peptide was identified by labeling the active-site serine with [ 3 H] diisopropylfluorophosphate. Peptides ...
Tumor necrosis factor-induced alterations in circulating leukocyte populations
(Elsevier, 1986-12-15)
Tumor necrosis factor is a potent agent possessing diverse biological functions. We investigated the effects of intravenous administration of human recombinant tumor necrosis factor (TNF) on immune cell populations in CBA/J ...
Estimating population birth rates of zooplankton when rates of egg deposition and hatching are periodic
(Springer-Verlag, 1986-07)
I present a general method of computing finite birth and death rates of natural zooplankton populations from changes in the age distribution of eggs and changes in population size. The method is applicable to cases in which ...
EPR of a novel high-spin component in activated hydrogenase from Desulfovibrio vulgaris (Hildenborough)
(Elsevier, 1986-05-26)
The EPR of reoxidized hydrogenase from Desulfovibrio vulgaris (H.) has been reinvestigated. In contrast to other workers [(1984) Proc. Natl. Acad. Sci. USA 81, 3728-3732] we find the axial signal with g = 2.06; 2.01 to be ...
Regulation of macrophage tumor necrosis factor production by prostaglandin E2
(Elsevier, 1986-05-29)
We have studied the role of prostaglandin E2 on the modulation of tumor necrosis factor by immunologically elicited and lipopolysaccharide treated murine macrophages. Indomethacin, a potent inhibitor of prostaglandin E2 ...
Absence of xanthine oxidase or xanthine dehydrogenase in the rabbit myocardium
(Elsevier, 1986-12-30)
We directly measured the activity of the enzymes xanthine oxidase and xanthine dehydrogenase in rabbit and rat hearts, using a sensitive radio-chemical assay. Neither xanthine oxidase activity nor xanthine dehydrogenase ...
What regulates secretion of non-stored proteins by eukaryotic cells?
(Wiley Subscription Services, Inc., A Wiley Company, 1986-05)
Protein secretion is conventionally viewed as taking place by either of two cellular routes, a regulated pathway, involving external stimuli and secretory granules, and a presumptive ‘constitutive’ pathway, which does not ...
