ISSN: 1471-4159Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Abstract: The somatodendritic release of dopamine in substantia nigra previously has been suggested to be nonvesicular in nature and thus to differ from the classical, exocytotic release of dopamine described for the dopaminergic nerve terminal in striatum. We have compared the effects of reserpine, a compound that disrupts vesicular sequestration of monoamines, on the storage and release of dopamine in substantia nigra and striatum of rats. Reserpine administration (5 mg/kg, i.p.) significantly decreased the tissue level of dopamine in substantia nigra pars reticulata, substantia nigra pars compacta, and striatum. In these brain areas, reserpine-induced reductions in tissue dopamine level occurred within 2 h and persisted at 24 h postdrug. In vivo measurements using microdialysis revealed that reserpine administration rapidly decreased the extracellular dopamine concentration to nondetectable levels in substantia nigra as well as in striatum. In both structures, it was observed that reserpine treatment significantly attenuated the release of dopamine evoked by a high dose of amphetamine (10 mg/kg, i.p.) given 2 h later. In contrast, dopamine efflux in response to a low dose of amphetamine (2 mg/kg, i.p.) was not altered by reserpine pretreatment either in substantia nigra or in striatum. The present data suggest the existence, both at the somatodendritic and at the nerve terminal level, of a vesicular pool of dopamine that is the primary site of transmitter storage and that can be displaced by high but not low doses of amphetamine. The physiological release of dopamine in substantia nigra and in striatum is dependent on the integrity of this vesicular store.Type of Medium: Electronic ResourceURL: -

Published 1995Staff ViewISSN: 1574-6968Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyNotes: Abstract A spontaneous Thiosphaera pantotropha mutant (Tp9002) that is able to grow on methanol has been isolated. With hybridization experiments it has been demonstrated that mxaF, the gene encoding the large subunit of methanol dehydrogenase, is absent from T. pantotropha. In Tp9002, a dye-linked enzyme activity was found with a substrate specificity similar to that of the dye-linked ethanol dehydrogenase from Pseudomonas aeruginosa. The N-terminus of a 26-kDa cytochrome c, exclusively synthesized in Tp9002, is homologous to the N-terminus of the electron acceptor of ethanol dehydrogenase. These results suggest that in Tp9002 a dye-linked ethanol dehydrogenase is responsible for methanol oxidation, using a 26-kDa cytochrome c as electron acceptor.Type of Medium: Electronic ResourceURL: -

Mean pulmonary artery and right atrial pressures and pulmonary artery as well as peripheral venous ANF plasma concentrations were measured in 24 patients before and after coronary angioplasty (PTCA) continuously at rest and during exercise: At rest, both pressure and ANF-values remained unchanged before and after PTCA. At exercise, there was a decrease of mean pulmonary artery pressure (from 41.3±8.6 to 31.5±7.4 mmHg,p〈0.001), mean right atrial pressure (from 11.9±3.0 to 9.0±2.3 mmHg,p〈 0.001), pulmonary artery (282.5±191.0 to 207.3±157.2 pg/ml,p〈0.05) and peripheral venous (112.7±48.0 to 97.1±53.2 pg/ml, n.s.) ANF concentration after PTCA. We found no correlation between PTCA-induced changes of right arterial pressures and ANF concentrations, while changes of pulmonary artery pressures were significantly correlated to changes of peripheral venous (r=0.79,p〈0.001) as well as pulmonary artery (r=0.59,p〈0.01) ANF concentrations at exercise. In 6 of the 24 patients, however there was an inverse relationship between changes of pulmonary artery pressures and ANF concentrations. — Our data demonstrate a significant correlation between changes of ANF plasma level and pulmonary artery pressure values at exercise after PTCA. In the individual case however invasive pressure monitoring cannot be replaced by determination of ANF plasma levels.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-2234Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract When the space part of the wavefunction of the groundstate of atomic two-electron systems is taken to be Φ(1, 2)=u(1)v(2)+v(1)u(2), where u=exp(−ar) and v=exp(−br), the parameters a and b as well as the energy associated with Φ(1,2) can be determined in the form of power series involving the nuclear charge Z. For small values of Z the convergence of these series is rather slow. The quantities mentioned, however, may be determined to any degree of accuracy by a method of stepwise approximation.Type of Medium: Electronic ResourceURL: -

ISSN: 1434-601XKeywords: 25.70.Ij ; 25.70.LmSource: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract A Langevin Monte Carlo method based on the surface friction model is used to investigate the competition between fusion and deep-inelastic collisions close to the barrier. Data for the58Ni+112,124Sn systems are analyzed. The measured excitation functions for fusion are well reproduced, whereas the calculated deep-inelastic cross sections deviate somewhat from experiment. Predictions for the corresponding spin distributions are made. Contrary to what is usually assumed they are not well separated in 1-space.Type of Medium: Electronic ResourceURL: -

ISSN: 0020-7608Keywords: Computational Chemistry and Molecular Modeling ; Atomic, Molecular and Optical PhysicsSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyDescription / Table of Contents: L'état fondamental des systèmes atomiques à deux électrons est décrit par des fonctions variationelles “échellonnées” de type \documentclass{article}\pagestyle{empty}\begin{document}$$ \phi _{\alpha k} = e^{ - (Z - 1 + e^{ - \alpha kr})kr} $$\end{document} et \documentclass{article}\pagestyle{empty}\begin{document}$$ \phi _{\beta \alpha k} = e^{ - (\beta + e^{ - \alpha kr})kr} $$\end{document} Le “scale factor” k a été introduit pour satisfaire au théorème du viriel. Sauf l'énergie totale, on a calculé les valeurs moyennes de plusieurs opérateurs à un électron. Ces résultats ont été comparés aux ceux obtenus avec d'autres fonctions variationelles.La fonction φαk déjà représente une bonne approximation de la solution Hartree-Fock, tandis qu'avec la fonction φβαk les résultats Hartree-Fock sont pratiquement reproduits.Abstract: Variationsfunktionen mit einem Koordinatenstreckungsfaktor k, von der Form \documentclass{article}\pagestyle{empty}\begin{document}$$ \phi _{\alpha k} = e^{ - (Z - 1 + e^{ - \alpha kr})kr} $$\end{document} und \documentclass{article}\pagestyle{empty}\begin{document}$$ \phi _{\beta \alpha k} = e^{ - (\beta + e^{ - \alpha kr})kr} $$\end{document} werden auf den Grundzustand atomarer Zweielektronensysteme angewendet. Der Faktor k wird eingeführt um dem Virialsatz zu befriedigen.Ausser der Energie werden Mittelwerte von mehreren Einelektronoperatoren berechnet und mit entsprechenden Resultaten für andere Variationsfunktionen verglichen.Die Funktion φαk schon representiert eine gute Annäherung zu der Hartree-Fock-Lösung, während mit der Funktion φβαk die Hartree-Fock-Resultate praktisch reproduziert werden.Notes: Scaled variational functions of the form \documentclass{article}\pagestyle{empty}\begin{document}$ \phi _{\alpha k} = e^{ - (Z - 1 + e^{ - \alpha kr})kr} $\end{document}, where Z is the nuclear charge and α is a parameter, and \documentclass{article}\pagestyle{empty}\begin{document}$ \phi _{\beta \alpha k} = e^{ - (\beta + e^{ - \alpha kr})kr} $\end{document}, where both α and β are parameters, are used for the description of the ground state of atomic two-electron systems in the independent particle model. The scale factor k has been introduced in order to satisfy the virial theorem.Apart from the energy, a number of one-electron expectation values have been calculated and the results are compared with those obtained from other variational functions.The function φαk yields already a good approximation to the Hartree-Fock solution whereas with the function φβαk the Hartree-Fock results are practically reproduced.Additional Material: 13 Tab.Type of Medium: Electronic ResourceURL: -

ISSN: 0020-7608Keywords: Computational Chemistry and Molecular Modeling ; Atomic, Molecular and Optical PhysicsSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: In previous work on electron subshell filling, the existence condition of the integrals involved has not been taken into proper account. As a result, part of the calculated subshell occupation numbers is meaningless.In Theis' theory [9] the average number of electrons in a subshell is calculated as the difference between two integrals. With each of these integrals an existence condition is associated. Because of this, the number of electrons with angular momentum quantum number l can only be calculated for atoms of which the Z value is (much) larger than the corresponding empirical first-appearance Z value. Thus, the range of Z for which such numbers can be calculated, is restricted considerably, especially for larger values of l.Results obtained from a normalized version of Mason's approximation [13] to the exact Thomas-Fermi function, have been compared with a least-squares fit of the empirical subshell occupation numbers, and these are found to be as good as one may expect from a statistical theory.A lower bound to each of the empirical first-appearance Z values has been calculated. The results agree well with those reported in other work.Additional Material: 5 Tab.Type of Medium: Electronic ResourceURL: -

ISSN: 0020-7608Keywords: Computational Chemistry and Molecular Modeling ; Atomic, Molecular and Optical PhysicsSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: The Gaussian lobe representation of 2p and 3dxy functions of a one-electron atom has been reconsidered. Contrary to earlier results, it has been found that the minimum energy associated with the simplest case of these functions is reached when the expansion centers coincide with the nucleus. This also seems to be true for representations with larger expansion lengths. Under similar conditions, Whitten's octahedral representation of the 2p function gives a better energy value than Poshusta's tetrahedral one.Additional Material: 1 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 0020-7608Keywords: Computational Chemistry and Molecular Modeling ; Atomic, Molecular and Optical PhysicsSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: For the total atomic Thomas-Fermi (TF) energy many expressions in terms of the kinetic and potential energy contributions can be given. Thirty of these expressions exhibit either a maximum or a minimum if some variational approximation to the TF function is used. Three of these expressions, to note E, G, and J (see text) have been used in an optimization procedure, in which four two-parameter and two three-parameter approximate TF functions have been considered. One-parameter functions cannot be optimized, as the one parameter must be fixed to ensure proper normalization. It is found that optimization of E and G give reasonable and similar results, whereas the results of optimization of J are generally not very impressive. Where possible, expectation values of the type 〈rn〉 (with n = -1, 1, 2, and 3) have been calculated from ten approximate TF functions. A new estimate of the exact atomic TF energy, as well as of the derivative of the TF function at the origin, has been obtained.Additional Material: 5 Tab.Type of Medium: Electronic ResourceURL: -

ISSN: 0020-7608Keywords: Computational Chemistry and Molecular Modeling ; Atomic, Molecular and Optical PhysicsSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: For the Hartree-Fock ground state of atomic two-electron systems, the variational function of Wilson and Silverstone, φ(r) = (a + kr)-1 exp(-kr) / (4π)1/2, can be optimized in two complementary ways. For small values of the atomic number Z, all intergrals have been calculated numerically and optimization can be performed accurately. However, as Z increases, loss of significant figures is increasingly detrimental to the optimization process. For sufficiently large values of Z, the integrals may be replaced by asymptotic expansions in terms of (2a)-. As a result of optimization, the parameters and expectation values can be given as expansions in terms of (32Z)-1/2. Both methods yield good results for Z ≈ 25, so that the whole range of Z can be treated accurately. The results have been compared with those derived from other analytical two-parameter functions. It is found that φ(r) is indeed the outstanding two-parameter function, at least for small and intermediate values of Z.Additional Material: 3 Tab.Type of Medium: Electronic ResourceURL:
