Up-to-date concentrations of long-lived artificial radionuclides in the Tom and Ob rivers in the area influenced by discharges from Siberian chemical combine.

The Siberian Chemical Combine (SCC) is located in Seversk (formerly known as Tomsk-7) in the Tomsk Region of the Russian Federation. The main contribution of radionuclides in the SCC process water discharged into the Tom River was from the single-pass reactors, now removed from service (the last SCC reactor was shutdown on June 5, 2008). The data on the concentrations of (90)Sr, (137)Cs, (239,240)Pu and other artificial radionuclides in water, bottom sediments and flood-plain soils of the Tom and Ob rivers from Tomsk to the confluence of the rivers, are presented and discussed.

The current content of artificial radionuclides in the water of the Tobol-Irtysh river system (from the mouth of the Iset River to the confluence with the Ob River).

Data on content of (90)Sr, (137)Cs, (239,240)Pu and (3)H in water of the Tobol-Irtysh part of the Techa-Iset-Tobol-Irtysh-Ob river system (through which the "Mayak" PA radioactive wastes are transported) are presented and discussed. The data were received in 2004-2005 under the ISTC project on radioecological monitoring of the Tobol and Irtysh rivers. Monthly observations of (137)Cs, (90)Sr and (3)H content in water in the area of the Tobol and Irtysh confluence have been conducted starting from May 2004.

[Specific immune complexes and neutrophil injury test in the diagnosis of experimental glanders and melioidosis].

The authors have demonstrated the possibility of using solid-phase enzyme immunoassay to detect specific circulating immune complexes without their preliminary separation in guinea pigs infected with Pseudomonas mallei and Pseudomonas pseudomallei. They have examined the prospects of using neutrophil injury test and solid-phase enzyme immunoassay for the detection of specific immune complexes as additional tests used to predict the outcome of an infectious process in glanders and melioidosis.

[Yersinia pestis L-forms in rodents and ectoparasites].

Y. pestis L-forms and bacterial forms persist in the body of great gerbils for 40 days. L-forms are poorly phagocytized and can persist in phagocytes for a long time.
