West Nile Virus Isolation in Human and Mosquitoes, Mexico

West Nile virus has been isolated for the first time in Mexico, from a sick person and from mosquitoes (Culex quinquefasciatus). Partial sequencing and analysis of the 2 isolates indicate that they are genetically similar to other recent isolates from northern Mexico and the western United States

Zuev Institute of Atmospheric Optics SB RAS,1, Zuev Square, Tomsk, 634921, RussiaEthylene is a naturally occurring compound in ambient air that affects atmospheric chemistry and global climate. The C$_2$H$_4$ spectrum is available in databases only for the 1000 and 3000 cm$^{-1}$ ranges. In this work, {\em J. Quant. Spectrosc. Radiat. Transfer\/}, {\bf 111}, 2265--2278 (2010).}, the ethylene absorption spectrum was measured in the 6030-6250 cm$^{-1}$ range with the use of a high resolution Bruker IFS 125HR Fourier-spectrometer and a two-channel opto-acoustic spectrometer with a diode laser. As a secondary standard of wavelengths, the methane absorption spectrum was used in both cases. A preliminary analysis was realized thanks to the tensorial formalism developed by the Dijon group that is implemented in the XTDS software package, {\bf 251}, 102--113 (2008).}. We considered the two combination bands $\nu_5+\nu_9$ and $\nu_5+\nu_{11}$ as an interacting dyad. Parameters for the $\nu_9/\nu_{11}$ dyad were fitted simultaneously from a re-analysis of previously recorded supersonic expansion jet FTIR data, while parameters for the $v_5=1$ Raman level were taken from literature. More than 600 lines could be assigned in the 6030-6250 cm$^{-1}$ region (and also 682 in the 2950--3150 cm$^{-1}$ region) and effective Hamiltonian parameters were fitted, including Coriolis interaction parameters. The dyad features are globally quite well reproduced, even if there are still problems at high $J$ values
