Multiparametric MR Imaging Features of Primary CNS Lymphomas.

Objective: Primary central nervous system lymphomas (PCNS) are relatively rare tumors, accounting for about 4% of all brain tumors. On neuroimaging, they are characterized by a low MR signal in T1, isointense in T2, bright uniform contrast enhancement, and diffusion restriction. The aim of this study is to note the lack of effectiveness of the MR/CT perfusion technique in complex multiparametric imaging in the differential diagnosis of primary lymphomas of the central nervous system in comparison with highly malignant gliomas and brain metastases.

[Construction of recombinant strain Brevibacillus choshinensis for chimeric borrelia Dbpa antigen production.].

The aim of this work was creation of recombinant chimeric protein using TAKARA expression system Brevibacillus choshinensis with fused gene dbpAAG, which include the parts of dbpAA and dbpAG genes coding the major antigenic determinants of decorinbinding proteins А (DbpA) from two species of borreliosis agents - Borrelia afzelii and Borrelia gаrinii. Such plasmid should be able to support the synthesis of recombinant chimeric polypeptide consisting immunogenic domains of DbpA Borrelia afzelii and Borrelia gаrinii in the stable and soluble forms, that important for effective using in Lyme diseases serodiagnosis. We chose the TAKARA expression system based on the strain Brevibacillus choshinensis and plasmid pNCMO2.

Revealing Color Forces with Transverse Polarized Electron Scattering.

The Spin Asymmetries of the Nucleon Experiment measured two double spin asymmetries using a polarized proton target and polarized electron beam at two beam energies, 4.7 and 5.9 GeV.

Comparative genome analysis of novel Podoviruses lytic for hypermucoviscous Klebsiella pneumoniae of K1, K2, and K57 capsular types.

Hypermucoviscous (HV) strains of capsular types K1, K2 and K57 are the most virulent representatives of the Klebsiella pneumoniae species. Eight novel bacteriophages lytic for HV K. pneumoniae were isolated and characterized.

New Measurement of the π0 radiative decay width.

High precision measurements of the differential cross sections for π0 photoproduction at forward angles for two nuclei, 12C and 208Pb, have been performed for incident photon energies of 4.9-5.5 GeV to extract the π0→γγ decay width.
