B.S. Zhukov and his Research Approach to the Study of Antiquities of the IV–I Millennium BC of the Eastern Europe Forest Zone

The paper considers methodological approaches in B.S. Zhukov’s scientific activity, one of the bright representatives of Russian archaeology in the 20s of the XX century. The basic principles of the paleoethnology he used in his studies are presented. An overview of the speeches of leading Russian ethnologists and paleoethnologists at the meetings of 1926 and 1927 is given. It is emphasized that the main problems discussed there were related to the development of the cultural-historical method. The main theses of B.S. Zhukov's main work "The theory of chronological and territorial modifications..." of 1929 are generalized. A high assessment is given to this work, which, firstly, demonstrated certain methods of analytical work with sources and, secondly, put extensive material of the IV–I millennium BC in the system, mainly from the territory of the Volga forest region. Innovative methods of study pottery collections introduced by B.S. Zhukov are considered

Comparative Analysis of Approaches and Treatment Results of Patients with Early and Nonearly Rheumatoid Arthritis

The article presents the results of a comparative analysis of different therapy regimens impact on the effectiveness of treatment of patients with early and late rheumatoid arthritis in steady-state. Data on ongoing basis anti-inflammatory therapy of rheumatoid arthritis and the treatment of associated conditions were obtained by continuous copying from case histories of hospital department patients. The observations lasted 12 months. The activity of rheumatoid arthritis before and after the treatment was determined by the DAS 28 (Disease Activity Score) index. The treatment results were evaluated as per the laboratory research and the DAS 28 index, including the counting of painful and swollen joints, erythrocyte sedimentation rate, and health assessment of the patient on a visual analogue scale

Perspectives of using sodium alginate with different molecular weight in the complex cancer therapy

The article presents the results of screening research of influence of sodium alginate with different molecular weight on the development of transplantable tumor in mice and the effectiveness of cytostatic treatment. It was determined that sodium alginates with both high (М = 403 kDa) and low (M = 1-10 kDa and M = 1 kDa) molecular weight suppress growth of Ehrlich ascites carcinoma; using sodium alginate (M = 20-30 kDa) in the scheme of chemotherapy increases effectiveness of treatment. Alginates with low molecular weight arrest development of dissemination of Lewis lung carcinoma and sodium alginates (M = 403 kDa and M = 20-30 kDa) in combination with cyclophosphan increase its antimetastatic effect

Phase separation effects and the nematic-isotropic transition in polymer and low molecular weight liquid crystals doped with nanoparticles

Properties of the nematic–isotropic phase transition in polymer and low molecular weight liquid crystals doped with nanoparticles have been studied both experimentally and theoretically in terms of molecular mean-field theory. The variation of the transition temperature and the transition heat with the increasing volume fraction of CdSe quantum dot nanoparticles in copolymer and low molecular weight nematics has been investigated experimentally and the data are interpreted using the results of the molecular theory which accounts for a possibility of phase separation when the system undergoes the nematic–isotropic transition. The theory predicts that the nematic and isotropic phases with different concentrations of nanoparticles may coexist over a broad temperature range, but only if the nanoparticle volume fraction exceeds a certain threshold value which depends on the material parameters. Such unusual phase separation effects are determined by the strong interaction between nanoparticles and mesogenic groups and between nanoparticles themselves
