Single unit discrimination of fish odours released by char (Salmo alpinus L.) populations
(Elsevier, 1974)
1. 1. Dilute fish odours from four distinct char populations elicited differential responses from char olfactory bulb cells.2. 2. Differential sensory responses produced by odours from migratory and non-migratory populations ...
Enzyme stereoselectivity: The reversible reaction catalyzed by 2-keto-4-hydroxyglutarate aldolase of Escherichia coli
(Elsevier, 1975-08-04)
SummaryThe condensation of [3-3H3]-pyruvate with glyoxylate in 3HOH to form [3-3H2]-ketohydroxyglutarate was catalyzed by ketohydroxyglutarate aldolase of Escherichia coli to study the stereochemical behavior of the enzyme. ...
The use of fluorescein-conjugated Bandeiraea simplicifolia B4-isolectin as a histochemical reagent for the detection of [alpha]--galactopyranosyl groups , : Their occurrence in basement membranes
(Elsevier, 1979-05)
The Bandeiraea simplicifolia B4-isolectin, which combines specifically with [alpha]--galactopyranosyl groups, has been conjugated with fluorescein isothiocyanate and demonstrated to be a reliable histochemical probe for ...
Structural studies of capsular polysaccharide of type XII diplococcus pneumoniae
(Elsevier, 1974-10)
The capsular polysaccharide of Diplococcus pneumoniae Type XII contains residues of -glucose and -galactose in a molar ratio of 2:1. The methylated polysaccharide yielded upon hydrolysis 2,3,4,6-tetra- and 3,4,6-tri-O-me ...
Functional significance of biological variability
(Elsevier, 1977)
The variability of biological matter contributes to both its adaptability and reliability. To represent the structure of this variability we treat a complete biological system (e.g. community and environment) as a system ...
Principle of superposition-free memory
(Elsevier, 1977-07-21)
The requirement that memory be superposition-free imposes a restrictive condition on the structure of neural models. A simple model which satisfies this condition consists of two levels of neurons, with primary level neurons ...
Isolation of plasma membranes from bovine corpus luteum possessing adenylate cyclase, 125I-hCG binding and Na---K-ATPase activities
(Elsevier, 1974-01-23)
Plasma membranes from bovine corpora lutea have been purified by sucrose density gradient centrifugation. The purified membranes, in addition to binding 125I-hCG, also possess hCG-stimulated adenylate cyclase and Na---K-ATPase. ...
Regulation of leucine transport and binding proteins in Escherichia coli
(Wiley Subscription Services, Inc., A Wiley Company, 1976-12)
No Abstract.
Stimulation of the gerbil's gustatory receptors by disaccharides
(Elsevier, 1976-07-16)
The gustatory responses from the chorda tympani nerve of the Mongolian gerbil, Meriones unguiculatus, were with 13 disaccharides. Sucrose was the most stimulatory sugar.The ability of fructosyl glycosides to stimulate amy ...
Histochemistry of granular (poison) secretion in the skin of the frog, Rana pipiens
(Wiley Subscription Services, Inc., A Wiley Company, 1973-12)
There are two types of granular glands in the skin of leopard frogs ( Rana pipiens ). Cellular glands produce fine intracellular granules rich in carbohydrate, carboxylic acids, tyrosine and sulfur-containing amino acids. ...
