(Kluwer Academic Publishers, 1992)Experimental values of the free energies of cation binding to the cyclic depsipeptide molecule, valinomycin, obtained from Pedersen-type salt extraction measurements, provide data against which it is possible to test the ...
-
(Humana Press, 1997)Investigation of phototransduction in invertebrate photoreceptors has revealed many physiological and biochemical features of fundamental biological importance. Nonetheless, no complete picture of phototransduction has yet ...
-
(1997)Univariate and multivariate statistical analyses of 39 meristic characters recorded for 12 samples of the lizard Liolaemus monticola were used to compare geographical variation in morphology with chromosomal races north ...
-
(1988)Correlation energy differences have been evaluated using an empirical polarization potential for the two-, three-, and four-electron atom series. In contrast to local-density approximations the Z dependency of the correlation ...
-
(Academic Press Inc., 1997)Glycogen synthesis following glucose microinjection in frog oocytes proceeds preferentially by an indirect pathway involving gluconeogenesis from triose compounds. Because of the known regulatory role of fructose-2,6-bisP ...
-
(1997)1. Conductance of heterotrimeric rat epithelial Na+ channels (α,β,γ-rENaCs) for Li+ and Na+ in planar lipid bilayers was a non-linear function of ion concentration, with a maximum of 30.4 ± 2.9 pS and 18.5 ± 1.9 pS at 1 M ...
-
(2008)We give examples of generalized modular forms with the property that their divisors are supported at the cusps and the exponents in their q-product expansions take infinitely many values. © 2007 Springer Science+Business ...
-
(Kluwer Academic/Plenum Publishers, 1996)1. Expression of the apamin-sensitive K+ channel (SK+) in rat skeletal muscle is neurally regulated. The regulatory effect of the nerve over the expression of some muscle ion channels has been attributed to the electrical ...
-
(1973)The models for electronic phase transitions of Ce1-xLax alloys are critically examined. The ideas put forward in the preceding paper are shown to be inconsistent and to lead to unphysical results. Finally, an experimental ...
-
(1997)In this work we establish the chromosomal composition of a wild-type, one astaxanthin and two β-carotene overproducer strains of the red yeast Phaffin rhodozyma. The method used has been pulsed field gel electrophoresis, ...
-
(1983)The electrochemical behaviour of NN′-thiobispiperidine and NN′-thiobismorpholine in dimethyl sulphoxide at low water content has been studied by cyclic voltammetry. Electro-oxidation in this medium, producing SO<inf&g ...
-
(1996)Invertebrate visual transduction involves a second messenger cascade process that leads to an increase in membrane conductance. The identity of the second messenger that gates the light-dependent channels is presently a ...
-
(1996)Objective: There is no endocrine test which is completely reliable for the confirmation of Cushing's syndrome and in separation of the various aetiologies. We have tested the hypothesis that overnight dexamethasone ...
-
(1995)An interface to record analog signals from DC to 20 kHz on the stereo sound channels of video cassette recorders is described. This interface is an effective solution for the implementation of experiments requiring ...
-
(1974)The effects due to localized spin fluctuations (LSF) in dilute superconducting alloys are investigated. Expressions for the critical temperature Tc as function of impurity concentration nI and the specific heat jump at the ...
-
Intestinal epithelia (Caco-2) cells acquire iron through the basolateral endocytosis of transferrin (1996)Although the absorption of iron through the intestinal epithelia is inversely related to body iron stores, the mechanisms by which the enterocytes sense body iron stores are unknown. Polarized enterocytes have transferrin ...
-
(2007)We study commutative algebras A over fields of characteristic ≠2, 3 which satisfy the identity β{x(y(xx)) - x(x(xy))} + γ{y(x(xx)) - x(x(xy))} = 0. We do not assume power-associativity. We find the Peirce decomposition of ...
-
(1995)The reproductive systems of three species of Nothofagus, N. dombeyi (Mirb.) Oerst., N. nitida (Phil.) Krasser and N. obliqua (Mirb.) Oerst. (Fagaceae), were studied in their natural forest habitats in Valdivia, Chile, using ...
