Asian and Siberian ginsengs contain glycosides with structural similarities to digoxin. We studied potential interference of ginseng in 5 digoxin immunoassays in 3 Asian (2 liquid extracts, 1 capsule) and 3 Siberian ginseng preparations (1 liquid extract, 2 capsules). With the fluorescence polarization immunoassay (FPIA), we observed apparent digoxin activity in 1 Asian liquid preparation and i...

Siberian hamsters use spontaneous daily torpor, a state of hypometabolism and hypothermia, to save energy during winter. Multiple neuroendocrine signals set the scene for spontaneous torpor to occur, and several brain areas have been identified as potential sites for torpor regulation. Here, we summarize the known mechanisms of a fascinating physiological state in the Siberian hamster.

Selecting seeds for long-term storage is a key factor for food hoarding animals. Siberian chipmunks (Tamias sibiricus) remove the pericarp and scatter hoard sound acorns of Quercus mongolica over those that are insect-infested to maximize returns from caches. We have no knowledge of whether these chipmunks remove the pericarp from acorns of other species of oaks and if this behavior benefits se...

We examined genetic variation on the nonrecombining portion of the Y chromosome (NRY) to investigate the paternal population structure of indigenous Siberian groups and to reconstruct the historical events leading to the peopling of Siberia. A set of 62 biallelic markers on the NRY were genotyped in 1432 males representing 18 Siberian populations, as well as nine populations from Central and Ea...

The objective of this study was to test the potential for using a single-entry procedure to revegetate Russian knapweed– and green rabbitbrush–infested rangeland. I hypothesized that simultaneously applying an herbicide and seeding in the fall would produce the highest establishment and growth of desired species. For Russian knapweed, treatments included three seeding rates (zero, low, and high...

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...

Although new antidiabetic agents are introduced, alternative medicine with natural compounds such as ginseng offer a potential benefit, as they have a wide margin of safety with no no side-effects. Following informed consent patients with type 2 diabetes (oral medication 80%, insulin therapy 20%) were randomly assigned to receive an extract of Siberian (480 mg/day; n = 27) American (Panax) gins...

knife. Only one knife was found, and, according to both men's stories, only one knife was used. Not much inference could be drawn from the situati on or direction of the wounds; though the fact that the largest of the three sligh t wounds on Inait's throat was deepest on the right, and tailed off to the left, was rather against its having been selfinflicted. The case against Sahadut was dismiss...

This paper presents a 2-D model of the methane cycle for the Siberian continental margin, including permafrost, hydrates and transient fluxes. Model is described in a differential way compared to the initial version used for another region (section 2). Results are presented (section 3) concerning initial spinup, impact of freshwater hydrology, glacial cycles and upcoming global warming. A discu...
