Protein-carbohydrate interaction : VIII. A turbidimetric method for the analysis of -mannose
(Elsevier, 1967-08)
A unique, spectrophotometric method for the quantitative of -mannose in the presence of other sugars is described. The procedure depends on the degree to which the turbidity formed on interaction of concanavalin A with ...
Effects of hyperthermia on Tetrahymena : I. Localization of acid hydrolases and changes in cell ultrastructure
(Elsevier, 1969-06)
The effects of hypothermia on Tetrahymena pyriformis (E) were studied. Protein synthesis was greatly inhibited at elevated temperatures (33.5-34 [deg]C), although the rate of protein turnover was not initially greater than ...
Sodium movement across the blood-brain barrier in newborn and adult rats and its autoradiographic localization
(Elsevier, 1968-07)
The net rate and structural specificity of 22Na entry into newborn and adult rat brain after intravenous injection were investigated.After a single injection, the half-time of sodium entry into adult rat brain was about ...
The amino acid substitution and some chemical properties of a variant human erythrocyte carbonic anhydrase: Carbonic anhydrase Id Michigan
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1967-09)
Carbonic anhydrase Id Michigan , an electrophoretic variant of human red cell carbonic anhydrase I, was purified from erythrocytes obtained from an individual heterozygous for the trait. Primary structural analysis indicates ...
The structures of the glia and of the synapses in the sympathetic chain of man
(Springer-Verlag, 1960-07)
Del Rio Hortega teilte die Glia der sympathischen und spinalen Ganglien in 2 Gruppen ein: 1. die perisomatische Glia, welche das Perikaryon der Parenchymzellen mit 2 übereinandergelagerten Schichten umgibt und 2. periaxonale ...
Metamorphic changes of dermis in skin of frog larvae exposed to thyroxine
(Elsevier, 1963)
Larvae of Rana pipiens immersed in a strong thyroxine solution at Taylor-Kollros stages VI-VIII survived up to 7-8 days. Samples of head skin were fixed daily and prepared for electron microscopy.Protoplasmic processes ...
The plateau phase of growth of the L-M strain mouse cell in a protein-free medium : II. Prolongation of the plateau phase by supplemental glucose
(Elsevier, 1965-01)
Supplementation of glucose at the beginning of the plateau phase has been shown to extend the duration of this phase by as much as fourfold in suspension cultures of L-M strain mouse cells in a protein-free medium.The role ...
The metabolic responses of the common iguana, Iguana iguana, to activity under restraint
(Elsevier, 1968-10)
1. 1. In the iguana, standard metabolism increased with temperature with a Q10 of 2[middle dot]24. Metabolic scope was greatest at 32[deg]C, decreasing above and below this temperature. Resting and post-activity heart rates ...
Effect of tetranitromethane on the aldolase and [beta]-decarboxylase activities of bovine liver 2-keto-4-hydroxyglutarate aldolase
(Elsevier, 1969-09-10)
Treatment of bovine liver 2-keto-4-hydroxyglutarate aldolase with tetranitromethane at pH 8.0 and room temperature rapidly and irreversibly destroys two known catalytic properties of this enzyme, namely, the reversible ...
Hippocampal lesions and active avoidance
(Elsevier, 1968-09)
Rats with lesions of the hippocampus were impaired relative to normal rats in the acquisition and retention of a one-way active avoidance task, but were superior to normal and partially neodecorticate rats in the acquisition ...
