Patient recovering from traumatic vegetative state has suddenly died from cardiac arrest. In-life improvement of consciousness appeared after reduction of generalized spasticity due to botulinum toxin administration. Neuropathologic examination revealed Musashi1+, Nestin+, PCNA+, and Ki67+ cells in the hippocampus,...

Character of Immune Disturbances and Their Correction by Including the Interferon Inductor in Complex Therapy for Turboperitoneal Infertility Associated with Chlamydial Infection.

Russian journal of immunology : RJI : official journal of Russian Society of Immunology

Uzlova TV, Teplova SN, Medvedev BI.
PMID: 12687123
Russ J Immunol. 1999 Jul;4(2):159-164.

The character of immune disturbances was studied in women with tuboperitoneal infertility associated with a chlamydial infection. The immunological methods included a study of the population and subpopulation composition of peripheral blood lymphocytes (CD3, CD7, CD22, CD4, CD8, ratio...

Experimental confirmation of quantum monodromy: the millimeter wave spectrum of cyanogen isothiocyanate NCNCS.

Physical review letters

Winnewisser BP, Winnewisser M, Medvedev IR, Behnke M, De Lucia FC, Ross SC, Koput J.
PMID: 16384372
Phys Rev Lett. 2005 Dec 09;95(24):243002. doi: 10.1103/PhysRevLett.95.243002. Epub 2005 Dec 05.

We have made energy-momentum maps for the experimental end-over-end rotational energy and the two-dimensional bending vibrational energy, both of which confirm the dominating effects of nontrivial quantum monodromy in cyanogen isothiocyanate. Accidental resonances in the rotational spectra yield accurate...

DOTP-manganese and -nickel complexes: from a tetrahedral network with 12-membered rings to an ionic phosphonate.

Inorganic chemistry

Kong D, Medvedev DG, Clearfield A.
PMID: 15530080
Inorg Chem. 2004 Nov 15;43(23):7308-14. doi: 10.1021/ic040076m.

DOTP (1,4,7,10-tetrakis(methylenephosphonic acid)-1,4,7,10-tetraazacyclododecane) was reacted hydrothermally with MnCl(2).2H(2)O and Ni(NO(3))(2).6H(2)O resulting in two structurally different compounds. Mn[C(3)NH(7)(PO(3)H(0.5))](4) crystallizes in the tetragonal space group P4/ncc, with a = 12.349(2) A, b = 12.349(2) A, c = 14.066(4) A, V =...

A model proton-transfer system in the condensed phase: NH4(+)OOH(-), a crystal with short intermolecular H-bonds.

The Journal of chemical physics

Churakov AV, Prikhodchenko PV, Lev O, Medvedev AG, Tripol'skaya TA, Vener MV.
PMID: 21033804
J Chem Phys. 2010 Oct 28;133(16):164506. doi: 10.1063/1.3493688.

The crystal structure of NH(4)(+)OOH(-) is determined from single-crystal x-ray data obtained at 150 K. The crystal belongs to the space group P2(1)/c and has four molecules in a unit cell. The structure consists of discrete NH(4)(+) and OOH(-)...

Impact of atmospheric clutter on Doppler-limited gas sensors in the submillimeter/terahertz.

Applied optics
