  • Human gut microbiota community structures in urban and rural populations in Russia 
    Tyakht A.; Kostryukova E.; Popenko A.; Belenikin M.; Pavlenko A.; Larin A.; Karpova I.; Selezneva O.; Semashko T.; Ospanova E.; Babenko V.; Maev I.; Cheremushkin S.; Kucheryavyy Y.; Shcherbakov P.; Grinevich V.; Efimov O.; Sas E.; Abdulkhakov R.; Abdulkhakov S.; Lyalyukova E.; Livzan M.; Vlassov V.; Sagdeev R.; Tsukanov V.; Osipenko M.; Kozlova I.; Tkachev A.; Sergienko V.; Alexeev D.; Govorun V. (2013)
    The microbial community of the human gut has a crucial role in sustaining host homeostasis. High-throughput DNA sequencing has delineated the structural and functional configurations of gut metagenomes in world populations. ...
  • Mononuclear Mn(II), Co(II), and Cu(II) pivalates 
    Fursova E.; Romanenko G.; Sagdeev R.; Ovcharenko V. (2014)
    Mononuclear Mn(II), Co(II), and Cu(II) pivalates were synthesized for the first time. They were isolated as salts with a composition NBu 4[MPiv3], where Piv is the pivalate anion. In the structure of the [MnPiv3] and ...
  • Photoswitching of a thermally unswitchable molecular magnet Cu(hfac) 2Li-Pr evidenced by steady-state and time-resolved electron paramagnetic resonance 
    Barskaya I.; Tretyakov E.; Sagdeev R.; Ovcharenko V.; Bagryanskaya E.; Maryunina K.; Takui T.; Sato K.; Fedin M. (2014)
    Most photoswitchable molecular magnets exhibit thermally induced switching, as is typical of spin crossover (SCO), valence tautomerism and SCO-like phenomena. We report a rare case of a copper-nitroxide based molecular ...
