Psychophysiological Analysis of Thymoleptic Effects of Xenon in Humans.

This pilot study was aimed at evaluation of the translational potential of xenon as a potential antidepressant. In placebo-controlled double-blind study, 14 healthy right-handed volunteers were randomly assigned to 15-min inhalation session of either gas mixture with xenon (25%Хе/30%О/45%N) or placebo (70%N/30%О) with simultaneous recording of 64-channel EEG. To assess the dynamics and nature of emotional activation in response to xenon and placebo, we analyzed both the intensity of positive and negative emotions and individual alpha peak frequency (iAPF) of EEG.

The Trace Element Zinc in the Composition of Native Chorionic Gonadotropin.

Human chorionic gonadotropin (hCG) is a most important regulator of embryogenesis and spermatogenesis. Equally important for the development of the fetus is the trace element zinc, which is essential for sustainable fetal development. The involvement of hCG and zinc in the first trimester of pregnancy (embryogenesis) led us to question the possibility of their structural cooperation and inclusion in the native molecule chorionic gonadotropin and zinc atoms.

[Block formation in Citellophilus Tesquorum altaicus Ioff, 1936, fleas in relation to the sex of an insect].

Males and females of C. Tesquorum altaicus, the main vector of plague in its natural focus, were experimentally studied in different seasons (spring, summer) for their capacity of block formation. The experiments used 2 groups of fleas: the insects that have been infected in last autumn and hibernated and <> insects, a that year's breeding.

[Differences between two populations of Citellophilus tesquorum altaicus from the Tuva natural focus of plague].

Citellophilus tesquorum altaicus fleas from two natural (Karginsky and Barlyksky) populations have been studied. There are differences between the fleas of these populations in susceptibility to plague microbe. The adaptability and abundance of the causative organism in the body are higher in the fleas of the Barlyksky population.
