    Individual tumors of multifocal EB virus-induced malignant lymphomas in tamarins arise from different B-cell clones (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-05-10
    Description: Cotton-top tamarins were inoculated with sufficient Epstein-Barr virus to induce multiple tumors in each animal within 14 to 21 days. The tumors consisted of large-cell lymphomas that contained multiple copies of the Epstein-Barr virus genome and generated Epstein-Barr virus-carrying cell lines showing no detectable consistent chromosomal abnormality. Hybridization of tumor DNA with immunoglobulin gene probes revealed that each lymphoma was oligo- or monoclonal in origin and that individual tumors from the same animal arose from different B-cell clones. Thus the virus induced multiple transformation events in tamarins in vivo to cause malignant tumors resembling the Epstein-Barr virus-associated lymphomas of patients with organ transplants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cleary, M L -- Epstein, M A -- Finerty, S -- Dorfman, R F -- Bornkamm, G W -- Kirkwood, J K -- Morgan, A J -- Sklar, J -- CA 34233/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 May 10;228(4700):722-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2986287" target="_blank"〉PubMed〈/a〉

    Steuerung der elektronischen Struktur organischer Leiter am Beispiel von [NMP][TCNQ]-Charge-Transfer-Komplexen (1987)

    Notes: Der Austausch von Kationen gegen Neutralmoleküle ähnlicher Form und Polarisierbarkeit in einem hochleitfähigen („metallischen“) organischen Charge-Transfer-Komplex ermöglicht die gezielte Einstellung von dessen elektronischer Struktur vom viertel- zum halbgefüllten Band. Verwirklicht wurde dieses Konzept in idealer Weise am N-Methylphenazinium(NMP)-Salz des Tetracyanchinodimethan(TCNQ)-Anions; bei diesem Salz läßt sich das Kation partiell gegen Phenazin austauschen. Eine detaillierte Untersuchung der optischen, elektrischen und magnetischen Eigenschaften der so erhaltenen leitfähigen molekularen Festkörper führte zu einem besseren Verständnis der Physik eindimensionaler organischer Leiter und zur Neuinterpretation des Mechanismus des Elektrontransports in diesen Festkörpern. Es wurden Phänomene wie der Übergang von einem „Zwei-Ketten-Leiter“ mit niedriger Coulomb-Abstoßung zum „Ein-Ketten-Leiter“ mit hoher Coulomb-Abstoßung und ein durch Solitonen unterstützter Elektronentransport beobachtet.

    Model study of synchronization and other phenomena in light perturbation of the Briggs-Rauscher reaction (1985)

    Notes: Calculations are performed to model several phenomena observed when a photosensitive oscillating chemical reaction, the Briggs-Rauscher (BR) reaction, is subject to irradiation in a continuous-flow stirred-tank reactor. The BR mechanism proposed earlier by De Kepper and Epstein is supplemented by additional steps involving the photogeneration and subsequent reaction of iodine atoms. The calculations show qualitative agreement with the following experimentally observed phenomena: (a) change in the period and amplitude of oscillation as a function of the intensity of constant illumination, (b) synchronization between periodically varying illumination and the period of chemical oscillation, (c) phase shifts induced by single light pulses, and (d) dark steady states which are excitable by single light pulses and become oscillatory at appropriate levels of constant illumination.

    Control of the Electronic Structure of Organic Conductors as Exemplified by [NMP][TCNQ] Charge-Transfer Complexes (1987)
    Weinheim : Wiley-Blackwell

    Topics: Chemistry and Pharmacology
    Notes: Through replacement of cations with neutral molecules of similar shape and polarizability in a highly conducting “metal-like” change-transfer organic conductor, the deliberate control of the electronic structure from a quarter to a half-filled band is possible. This goal has been achieved with the N-methylphenazinium (NMP) salt of the tetracyanoquinodimethane (TCNQ) anion by partial replacement of the cation with phenazine. A detailed study of the optical, electrical, and magnetic properties of these conducting molecular solids has lead to the evolution of a broad understanding of the physics of one-dimensional organic conductors and a reinterpretation of the mechanism of electron transport in such solids. Phenomena such as switching from a low coulomb repulsion two-chain conductor to a high coulomb repulsion one-chain conductor as well as soliton-assisted electron transport are observed.

    Notes: The reaction between chlorite ion and thiourea has been studied both in a closed (batch) system and in a flow reactor (CSTR). The principal stoichiometry is given by \documentclass{article}\pagestyle{empty}\begin{document}$$ 2{\rm ClO}_{\rm 2} ^{\rm - } + {\rm CS(NH}_{\rm 2} {\rm)}_{\rm 2} + {\rm 2NH}_{\rm 4} ^ + + {\rm CO}_{\rm 2} + 2{\rm Cl}^{\rm - } + {\rm SO}_{\rm 4} ^{{\rm 2 - }} $$\end{document} In batch, the reaction displays an induction period, whose length is proportional to [CS(NH2)2]/[ClO2-] [H+], followed by the rapid buildup and disappearance of a ClO2 intermediate. At [ClO2-]/[CS(NH2)2] ratios between 2.5 and 3.5, a second peak in the ClO2 absorbance is observed. In the CSTR, this iodine-free system displays simple and complex periodic oscillation, bistability, aperiodic oscillation, and birhythmicity.

    Autocatalysis and bistability in the reaction between nitric acid and thiocyanate (1985)
    New York, NY : Wiley-Blackwell

    Topics: Chemistry and Pharmacology
    Notes: The reaction between nitric acid and thiocyanate has been studied both in batch and flow configurations. The batch reaction is autocatalytic with an induction period which is decreased by the addition of HNO2. At the nitric acid concentrations employed (1-10 M), a red NOSCNH+ intermediate is formed. The reaction in a flow reactor exhibits bistability. A model involving competitive reactions of SCN- and NOSCNH+ with NO2 is suggested, and computer simulations with this model give good agreement with both the batch and flow experiments.
