The mRNA expression of growth hormone (GH) gene in early development stages of Siberian sturgeon was investigated using RT-PCR method. Samples were collected from unfertilized eggs up to 50 days post hatched (dph) larvae in 11 different times. Ribosomal protein L6 (RPL6) transcripts were used as the internal standard during quantification of GH mRNA expression. The results showed that the GH mR...

Siberian snakes avoid crossing depolarizing resonances in circular accelerators by forcing the spin tune to half integer independent of beam energy. This concept has been proposed by Ya.S. Derbenev and A.M. Kondratenko in 1974 [1]. If only one Siberian snake is used, the invariant spin axis1 is in the horizontal plane. This is an interesting feature to deliver longitudinally polarized beam to i...

The VNTR loci D7S104, D11S129, D18S17, D20S15, and D21S112 in three indigenous Siberian populations were analyzed to determine the populations' genetic structure. Using the Kolmogorov-Smirnov test, we found that the Siberian indigenous populations of Surinda and Sulamai are separated at the D11S129 locus (p < 0.05). However, the population of Poligus is genetically homogeneous compared with the...

South Siberian Turkic languages are rich in sound symbolic subsystems, both in their lexica and in the productive morphophonology, but these systems remain to be adequately documented. This paper presents new field data on sound symbolism in two South Siberian Turkic languages: Tofa(lar) and Tuvan (including the unwritten Tsengel and Hovd dialects spoken in Mongolia). Sound symbolic word format...

Oriented samples of the Lov.'er Cambrian Sayan Go! Formation from Salaany Go!, Mongolia, were collected at roughly 5 m stratigraphic intervals for palaeomagnetic analysis. Progressive alternatingfield and thermal demagnetization isolated two magnetic components: a present-field overprint, typically removed by 10 mT fields and -200 °C heating: and a high-coercivity, high-unblocking-temperature (...

Many nontropical animals display physiological and behavioural changes in response to seasonal environmental cues including photoperiod (day length). Male Siberian hamsters (Phodopus sungorus) housed in short photoperiod undergo testicular regression accompanied by reduced circulating testosterone and decreased reproductive behaviour. By contrast to the majority of small mammals studied, aggres...

Genetic data consisting of immunoglobulin testing (GM and KM) from 631 Eskimos from 5 populations are reported. These populations are Savoonga, Gambell (St. Lawrence Island), Wales, King Island, and Mckenzie Delta, Baffin Island. The GM and KM haplotypes are analyzed and compared to those occurring in Greenland, Canadian, Alaskan, and Siberian Eskimos and to other Siberian indigenous population...

The mtDNA variation of 411 individuals from 10 aboriginal Siberian populations was analyzed in an effort to delineate the relationships between Siberian and Native American populations. All mtDNAs were characterized by PCR amplification and restriction analysis, and a subset of them was characterized by control region sequencing. The resulting data were then compiled with previous mtDNA data fr...
