Recombinant domains III of Tick-Borne Encephalitis Virus envelope protein in combination with dextran and CpGs induce immune response and partial protectiveness against TBE virus infection in mice.

Background: E protein of tick-borne encephalitis virus (TBEV) and other flaviviruses is located on the surface of the viral particle. Domain III of this protein seems to be a promising component of subunit vaccines for prophylaxis of TBE and kits for diagnostics of TBEV.

Methods: Three variants of recombinant TBEV E protein domain III of European, Siberian and Far Eastern subtypes fused with dextran-binding domain of Leuconostoc citreum KM20 were expressed in E.

[Search for RNA of the hepatitis E virus autochthonous for Russia in the most likely infection sources].

The research carried out for 30 years from the moment of hepatitis E virus (HEV) discovery has proved the presence of the autochthonous HEV in non-endemic areas: Europe and Russia. Monitoring of the HEV antibodies (anti-HEV) among the Russian population has revealed regions with increased seroprevalence that testifies to high probability of local HEV infection in these areas. Contact with HEV can represent special danger for patients of the risk groups.

[Development of methods of local hyperthermia to achieve more marked tumor pathomorphism].

Regular investigations on application of hyperthermia in oncology have been carried out since the second half of the 1950s. The usage of distant tissues heating faces considerable difficulties in maintenance of therapeutic temperature in the whole volume of the tumor. Thus, the use of interstitial hyperthermia is promising, especially, ferromagnetic hyperthermia which causes damage not only to central but also to peripheral zones of tumors.
