Role of glucose-1-phosphate and glucose-6-phosphate in glycogen synthesis by pigeon liver homogenate (1976)1. 1. Glucose-1-C14, G-6-P-1-C14 and G-1-P-l-C14 have been incubated with a pigeon liver homogenate. Incorporation of C14 into glycogen and CO2 were measured. 2. 2. The relative incorporation of C14 from G-6-P-1-C14 and ...

(1975)THE microinjection technique perfected by Gurdon and his collaborators 1,2 represents an excellent method for the study of the in vivo effects of drastically changing the molecular contents of the injected cells. We have ...

(2008)A technique for wavelength calibration promises to revolutionize observational astrophysics, in areas including planet searches and cosmology.
-
(1975)Increasing concentrations of chloride were found to increase the resolution between two visible absorbance spectral transitions associated with acidification of ferricytochrome c. Analysis of a variety of spectral and ...
-
(Società Italiana di Fisica, 1987)We introduce a new definition of symmetry transformations in quantum mechanics which contains the textbook definition as a special case. We find several conserved quantities associated with one (nonunitary) symmetry ...
-
(1991)We reanalyze a recent paper by Kim et al. [Phys. Rev. B 38, 5716 (1988)] regarding the kinetics of hydrogen uptake by niobium surfaces. We show that the kinetic analysis performed by these authors is incorrect. © 1991 The ...

(Springer-Verlag, 1975)The time course of the membrane currents in the node of Ranvier in which the sodium and potassium conductances have been blocked reveals asymmetries during and after the application of depolarizing and hyperpolarizing ...
-
(1975)It is shown that the energy-momentum tensor of the electromagnetic field, for an electron in a curved space, may be split into two dynamically independent parts. One of them, the radiation tensor, has the following remarkable ...
-
(1973)A continuous two‐hour water extraction procedure is proposed instead of the former 14‐hour method to remove the thioglucosides from rapeseed presscake meal (RSM). This new procedure produced a complete removal of isothiocyanates ...
-
(1973)Cell kinetics parameters were obtained for the three mitotic divisions leading to formation of stomata in the epidermis of the cotyledon of Allium cepa seedlings. Analysis of mitotic frequencies throughout the course of ...
-
(2008)We give a cohomological characterization of the set of conjugacy classes of finite subgroups of the projective multiplicative group of a finite dimensional algebra that become conjugate to a given group over some finite ...
-
(1986)By means of an iterative consistency method it has been determined a complete potential field for the urea molecule. The force constants set which interpretates well the vibrational spectra of urea and its deutero derivatives ...
-
(1972)Absorption spectral, circular dichroic spectral, and viscosity measurements indicate that the compact low-spin conformation characteristic of native cytochrome c is quantitatively recovered from its extended high-spin ...
-
(1991)Araucaria araucana seeds and seedlings respond to wounding after 48 h with a 3- to 4-fold increase of hydroxyproline-rich glycoproteins (HRGP) in the cell walls of the embryo and with a 15-fold increase in the cell walls ...

(1972)Changes in the fatty acid composition of egg‐yolk fat of hens fed diets with increasing fish meal content are studied by total fatty acid analysis. The fatty acid composition of the major lipid fractions in egg‐yolk fat ...
