    Notes: The monomer-dimer equilibria of 2,6- and 3,5-dimethylnitrosobenzenes in CDCI3 solution were investigated by 1H and/or 13C NMR spectroscopy. The mixed systems nitrosobenzene + 2,6-dimethylnitrosobenzene and 2,6-dimethylnitrosobenzene + 3,5-dimethylnitrosobenzene were also studied, and mixed azodioxy dimers were identified. In all systems exchange occurs exclusively between dimer and monomer species, rates and activation energies being calculated from time-dependent 1H 1D spectra and/or 1H 2D-EXSY spectra measured at different temperatures.

    Study of the monomer-dimer equilibrium of nitrosobenzene using multinuclear one- and two-dimensional NMR techniques (1987)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 25 (1987), S. 1007-1011 
    Details
    ISSN: 0749-1581
    Keywords: 13C ; 15N ; 17O NMR 13C ; 2D-EXSY ; nitrosobenzene ; activation energies ; Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: The monomer-dimer equilibrium of nitrosobenzene in CDCI3 solution was studied in the temperature range -50 to 30 °C using 13C, 15N and 17O NMR spectroscopy. Decreasing temperature favours the dimeric azodioxy species, and below ca 10 °C both cis and trans dimers were detected in addition to the monomer. The relative abundance of the trans dimer is low (≤6%) at all temperatures and this is the first report of its existence in solution. The monomer and dimer species were characterized by their 13C and 15N shifts, and exchange between them was measured quantitatively by 13C 2D-EXSY spectra. Exchange occurred exclusively between the cis-dimer and monomer and between the trans-dimer and monomer, activation energies, ΔG≠(298.15 K) being 65.8±0.1 and 70.0±0.3 kJ mol-1, respectively.

    Proton NMR data of some 1,3-benzodithioles (1986)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 24 (1986), S. 831-832 
    Details
    ISSN: 0749-1581
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The 1H NMR spectra of 1,3-benzodithiole and eight derivatives have been analysed. Signals of the protons in positions 4 and 7 are shifted downfield compared with those for the protons in positions 5 and 6. The inter-ring proton-proton couplings have been determined.

    Transmission of equine influenza virus to dogs (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-09-28
    Description: Molecular and antigenic analyses of three influenza viruses isolated from outbreaks of severe respiratory disease in racing greyhounds revealed that they are closely related to H3N8 equine influenza virus. Phylogenetic analysis indicated that the canine influenza virus genomes form a monophyletic group, consistent with a single interspecies virus transfer. Molecular changes in the hemagglutinin suggested adaptive evolution in the new host. The etiologic role of this virus in respiratory disease was supported by the temporal association of rising antibody titers with disease and by experimental inoculation studies. The geographic expansion of the infection and its persistence for several years indicate efficient transmission of canine influenza virus among greyhounds. Evidence of infection in pet dogs suggests that this infection may also become enzootic in this population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crawford, P C -- Dubovi, Edward J -- Castleman, William L -- Stephenson, Iain -- Gibbs, E P J -- Chen, Limei -- Smith, Catherine -- Hill, Richard C -- Ferro, Pamela -- Pompey, Justine -- Bright, Rick A -- Medina, Marie-Jo -- Johnson, Calvin M -- Olsen, Christopher W -- Cox, Nancy J -- Klimov, Alexander I -- Katz, Jacqueline M -- Donis, Ruben O -- New York, N.Y. -- Science. 2005 Oct 21;310(5747):482-5.

    Skeletal muscle as the potential power source for a cardiovascular pump: assessment in vivo (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-04-17
    Description: Skeletal muscle ventricles (SMVs) were constructed from canine latissimus dorsi and connected to a totally implantable mock circulation device. The SMVs, stimulated by an implantable pulse generator, pumped continuously for up to 8 weeks in free-running beagle dogs. Systolic pressures produced by the SMVs, initially of 139 +/- 7.2 mmHg and after 1 month of continuous pumping of 107 +/- 7 mmHg, were comparable to normal physiologic pressures in the adult beagles (114 +/- 21 mmHg). After 2 weeks of continuous pumping, the mean stroke work of the SMVs was 0.4 X 10(6) ergs, a performance that compares favorably with the animal's cardiac ventricles. This study shows that canine skeletal muscle which has not received prior training or electrical conditioning can perform sustained work at the high levels needed for an auxiliary cardiovascular pump. It might be possible eventually to use such muscle pumps in humans to assist the failing circulation and to provide support in children with certain types of congenital heart defects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Acker, M A -- Hammond, R L -- Mannion, J D -- Salmons, S -- Stephenson, L W -- HLBI 34778/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1987 Apr 17;236(4799):324-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2951849" target="_blank"〉PubMed〈/a〉
