Role of System Gly in glycine transport in monolayer cultures of liver cells
(Elsevier, 1981-01-15)
The high-affinity component of glycine uptake by the hepatoma cell line HTC and by the ordinary rat hepatocyte corresponds to System Gly, the agency serving for glycine uptake by pigeon red blood cells and rabbit reticulocytes, ...
GTP[gamma]S-stimulated hydrolysis of phosphatidyinositol-4,5-bisphosphate by soluble phospholipase C from human platelets requires soluble GTP-binding protein
(Elsevier, 1988-07-15)
GTP-binding activity was fractionated into two peaks (GI and GII) by chromatography on heparin-agarose. GTP-dependent PLC activity eluted as a single peak, which co-chromatographed with GTP-binding peak GII. Rechromatography ...
Decreased in vivo protein and phospholipid methylation after in vivo elevation of brain S-adenosyl-homocysteine
(Elsevier, 1981-02-27)
The administration of adenosine together with homocysteine resulted in a dose-related elevation of cerebral S-adenosyl-L-homocysteine without concomitant perturbation of S-adenosyl-L-methionine levels. The adenosine + ...
Optimal foraging and community structure: implications for a guild of generalist grassland herbivores
(Springer-Verlag, 1986-08)
A particular linear programming model is constructed to predict the diets of each of 14 species of generalist herbivores at the National Bison Range, Montana. The herbivores have body masses ranging over seven orders of ...
Unicircular structure of the Brassica hirta mitochondrial genome
(Springer-Verlag, 1987-03)
Restriction mapping studies reveal that the mitochondrial genome of white mustard ( Brassica hirta ) exists in the form of a single circular 208 kb chromosome. The B. hirta genome has only one copy of the two sequences ...
Tonofilament protein, a keratin from rat epidermis
(Elsevier, 1981-11-16)
Tonofilament protein from newborn rat epidermis was found to be antigenically related to mouse keratins. Tonofilament protein, like keratins, could be extracted with 8 M urea in Tris buffer. The yield was enhanced by the ...
Normalization of liver glucosylceramide levels in the "Gaucher" mouse by phosphatidylserine injection
(Elsevier, 1988-04-15)
A model of the human genetic disorder, Gaucher disease, can be rapidly generated in mice by the injection of emulsified glucosylceramide and an inhibitor of the lipid's hydrolase, conduritol B epoxide. The liver grows ...
Prey selection by the copepod Diacyclops thomasi
(Springer-Verlag, 1985-03)
1. Adult females of the predaceous copepod, Diacyclops thomasi , consistently selected for the soft-bodied rotifers Synchaeta pectinata, Polyarthra major and P. remata when presented various combinations of 8 rotifer species ...
Receptor binding, antagonist, and withdrawal precipitating properties of opiate antagonists
(Elsevier, 1983-06-20)
A number of opiate antagonists and the dextro isomers of some of these drugs were studied for antagonism of acute opiate effects on ilea isolated from opiate-naive guinea pigs, precipitation of a withdrawal contraction of ...
Immunohistochemical localization of enkephalin and ACTH-related substances in the pituitary of the lamprey
(Springer-Verlag, 1984-01)
The distributions of ACTH-, αMSH-, β LPH-, and enkephalin-related substances were determined immunohistochemically in the pituitary of the brook lamprey, Lampetra lamotenii . An antiserum directed against the middle region ...
