A generalization of the Goldman equation, including the effect of electrogenic pumps
(Elsevier, 1971-10)
An equation similar to the Goldman equation is derived for the steady-state diffusion of univalent ions across a membrane with arbitrary potential profile and in the presence of electrogenic pumps. The presence of electrogenic ...
Non-visual functions of crustacean eyestalk ganglia
(Springer-Verlag, 1971-03)
Ablation experiments demonstrated that in several crustacean groups, the proximal eyestalk ganglia are important in a variety of behavior patterns: 1. Chemical elicitation of feeding via the antennules is altered in lobsters, ...
Fatty acid and hydrocarbon hydroxylation in yeast: Role of cytochrome P-450 in
(Elsevier, 1971-02-05)
A soluble enzyme system which catalyzes the conversion of fatty acids to their [omega]-hydroxy derivatives and -alkanes to primary alcohols has been obtained from a strain of grown on tetradecane as the carbon source. The ...
Interactions of substrate and non-substrate effectors with p-hydroxybenzoate hydroxylase from
(Elsevier, 1971-12-03)
3,4-Dihydroxybenzoate (3,4-DOHB), 2,4-dihydroxybenzoate (2,4-DOHB), and benzoate facilitate the interaction of p-hydroxybenzoate hydroxylase with TPNH. The two dihydroxybenzoate effectors form 1:1 complexes with the enzyme, ...
Structure of the nerve myelin membrane: Proof of the low-resolution profile
(Elsevier, 1971-02-28)
In analyzing the low-angle X-ray diffraction patterns recorded from the normal and swollen myelin in frog sciatic nerve, a precise value is found for the center-to-center distance between the pair of membranes constituting ...
Genetic variation and evolution in the red cell carbonic anhydrase isozymes of macaque monkeys
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1971-04)
The electrophoretic phenotypes of the two isozymes of red cell carbonic anhydrase, CA I and CA II, are described in nine species of macaque monkeys from southeast Asia and Japan. Twelve phenotypes of CA I, apparently under ...
Receptor organization and function in Limulus chelae
(Springer-Verlag, 1971-09)
1. The opposed grasping surfaces of the digits of the chela of the Limulus walking leg have ridge-like pads of pliable cuticle. Receptors are present both on these pads and elsewhere on the surface of the chelae.
Quantitative genetic variation in carbonic anhydrase isozymes from tissues of the pig-tailed macaque, Macaca nemestrina
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1971-08)
Two isozymes of carbonic anhydrase (CA I and CA II) were quantified by a radio-immunoassay in 10 different tissues of the pig-tailed macaque. There were clearly differences in relative amounts of the two isozymes, indicating ...
Mathematical analysis and digital simulation of the control of erythropoiesis
(Elsevier, 1971-11)
A mathematical model is presented which represents the control system for erythropoiesis. In the model, it is postulated that the rate of erythropoiesis is controlled by a hormone, erythropoietin, which is released from ...
The uptake of pentazocine into brain
(Elsevier, 1971-06-15)
A simple procedure for the extraction from tissues and determination by gas chromatography of pentazocine was developed. The mean recovery from brain was 96%.The time- and dose-dependent uptake of pentazocine into the brain ...
