(1973)Energy gaps near the Fermi surface arising from magnetic Brillouin zone effects must be taken into account in order to understand the antiferromagnetism of europium metal. © 1973 Pergamon Press.
-
(1972)The model recently proposed by Ramírez and Falicov is generalized by the incorporation of the spin-orbit splitting of the 4f shell. This generalization provides an understanding of the fractional valence and magnetic ...
-
(1994)Myotonic muscular dystrophy is a genetic disease characterized mainly by muscle atrophy and myotonia, a repetitive electrical activity of muscle. In the present study, the possible role of apamin‐sensitive K+ channels in ...
-
(1995)The use of 3-fluoro-tyrosine as an alternative substrate for the enzyme tubulin:tyrosine ligase which catalyzes the incorporation of tyrosine into the α-tubulin subunit was investigated. The incorporation of tyrosine into ...
-
(1994)It is generally accepted that in frog full-grown oocytes glycolysis is absent and that carbon metabolic flux is largely directed to glycogen synthesis. Use of an anion exchange pellicular resin for analytical resolution ...
-
(1993)McNab (1986, 1988) has hypothesized that mammals using food with low energy content should exhibit basal metabolic rates (BMR) lower than those expected on the basis of their body mass (mb). That is, those species that ...
-
(Springer-Verlag, 1994)Four double-stranded RNA (dsRNA) molecules were isolated from Phaffia rhodozyma UCD 67-385. Their molecular sizes were approximately 4.3, 3.1, 0.9 and 0.75 kilobase pairs (kbp) as determined by agarose-gel electrophoresis ...
-
(Springer-Verlag, 1992)We have studied the properties of membrane patches excised from the transducing lobe of Limulus ventral photoreceptors. If patches are excised into an "internal" solution that resembles the ionic composition of the cytoplasm, ...
-
(1993)A low conductance calcium‐activated K+ channel is thought to regulate the rate of firing of several excitable cells. In skeletal muscle the expression of this channel is under nerve control. Previously, we reported that ...
-
(Springer-Verlag, 1983)Reactions of bis(diethylamino) and dimorpholinosulfane with [Cu(H2O)6](ClO4)2 in acetonitrile and with CuCl2·2H2O in ethanol yield Cu(I) compounds and SO2. The reaction product of dimorpholinosulfane and CuCl2 in ethanol ...
-
(1993)This paper describes a method for the quantitative determination of aluminium in haemodialysis concentrates, based on the adsorption on a static mercury drop electrode of the Al-1,2 dihydroxyantraquinone-3-sulphonic acid ...
-
(1993)The intrinsic fluorescence excitation and emission spectra of chicken brain tubulin showed the characteristic tryptophan fluorescence. The emission spectrum of Tb3+ in the presence of tubulin and GTP excited at 295 nm, ...
-
(Kluwer Academic Publishers, 1992)This study documents the stem size and age-structure in forests dominated by different species of Nothofagus in Torres del Paine National Park (51° S), in the Chilean Patagonian region. We also explored the relationship ...
-
(1972)In terms of the usual RKKY indirect exchange interaction, the spiral antiferromagnetic phase of Europium cannot be attributed to a 'nesting' of opposite faces of the tetracube portion of the Fermi surfaces. © 1972.
-
Light-dependent channels from excised patches of Limulus ventral photoreceptors are opened by cGMP (National Academy of Sciences, 1991)The identity of the second menenger that directly activates the light-dependent conductance in invertebrate photoreceptors remains unclear; the available evidence provides some support for cGMP and Ca2+. To resolve this ...
