Energy relations of winter roost-site utilization by American goldfinches ( Carduelis tristis )
(Springer-Verlag, 1985-12)
American goldfinches ( Carduelis tristis ) were observed roosting in Colorado blue spruce ( Picea pungens ), which comprised part of a mixed stand of conifers. Their winter roost-sites were distally situated among the most ...
IV. Effects of bombesin on behavior
(Elsevier, 1985-07-15)
This report describes the influence of bombesin on the gross behavior of goldfish, frogs, mice, rats, guinea pigs, rabbits, chicks, pigeons and monkeys. Goldfish, frogs, chicks and pigeons were overtly unaffected by bombesin ...
A possible correlation between the growth rate and the extent of DNA damage induced by radiodecay in mouse lymphoma cells
(Elsevier, 1985-04-16)
The extent of DNA single strand breaks resulting from the beta radiodecay of incorporated [3H]thymidine in DNA of mouse lymphoma cells appears to be related to the degree of growth inhibition. The extents of damage to DNA ...
A rapid, novel High Performance Liquid Chromatography method for the purification of Glutathione S-transferase: An application to the human placental enzyme
(Elsevier, 1985-04-16)
A simple High Performance Liquid Chromatography procedure is detailed for the purification of Glutathione S-transferase. The human placental transferase was used to assess its potential. Unlike conventional methods of ...
Cytological localization of adenosine kinase, nucleoside phosphorylase-1, and esterase-10 genes on mouse chromosome 14
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1985-03)
We have determined the regional locations on mouse chromosome 14 of the genes for mouse adenosine kinase (ADK), nucleoside phosphorylase-1 (NP-1), and esterase-10 (ES-10) by analysis of rearranged mouse chromosomes in ...
Cell proliferation after ischemic injury in gerbil brain
(Springer-Verlag, 1985-10)
Tritiated thymidine autoradiography was used to measure cellular proliferation after ischemic injury in gerbil brain. Gerbils were subjected to bilateral occlusion of the common carotid arteries which resulted in areas of ...
Preliminary characterization of cell surface glycoproteins associated with epidermal differentiation in the newborn rat
(Elsevier, 1985-10-15)
The cell surface of the newborn rat epidermis exhibits a discrete change in lectin-binding specificity from I-B4 (GS I-B4), specific for [alpha]-D-galactosyl residues, to agglutinin I (UEA), specific for [alpha]-L-fucose, ...
Racial differences in bumetanide-sensitive cotransport and N-ethylmaleimide-stimulated potassium efflux
(Elsevier, 1985-05-13)
Racial differences in erythrocyte potassium effluxes mediated by two loop-diuretic sensitive modes of cotransport were compared. In red cells loaded to contain approximately equimolar amounts of sodium and potassium, black ...
Arachidonic acid metabolites regulate interleukin-1 production
(Elsevier, 1985-04-30)
We have investigated the role of arachidonic acid metabolites in the regulation of interleukin-1 production by murine peritoneal macrophages. Indomethacin a potent inhibitor of prostaglandin synthesis caused a dose-dependent ...
Biogeochemical silica mass balances in Lake Michigan and Lake Superior
(Martinus Nijhoff/Dr. W. Junk Publishers; Martinus Nijhoff/Dr W. Junk Publishers ; Springer Science+Business Media, 1985-09)
Silica budgets for Lake Michigan and Lake Superior differ in several respects. Mass balance calculations for both lakes agree with previous studies in that permanent burial of biogenic silica in sediments may be only about ...
