Effects of Oxytocin and Thyroliberin on Anxiety in Male White Mice in Social Stress

E. P. Vinogradova, A. V. Kargin, N. A. Ogienko, D. A. Zhukov

Neuroscience and Behavioral Physiology > 2018 > 48 > 8 > 1019-1023

The effects of intranasal administration of oxytocin and thyroliberin solutions on changes in behavior in rats after moderate social stress were studied. Investigations were carried out on male Wistar rats (n = 100). Animals of experimental group 1 received intranasal oxytocin at a dose of 0.25 IU in 20 μl bilaterally and those of experimental group 2 received thyroliberin at a dose of 10 10 mmol...

The Effects of Intranasal Administration of Oxytocin on the Behavior of Rats with Different Behavioral Strategies Subjected to Chronic Mild Stress

E. P. Vinogradova, D. A. Zhukov

Neuroscience and Behavioral Physiology > 2018 > 48 > 3 > 333-336

Two groups of Wistar rats with opposite behavioral strategies – active and passive – were subjected to chronic mild stress. Half of the group of poststress animals received intranasal oxytocin (at a dose of 0.25 IU); their behavior was tested in the Porsolt test and their consumption of a sweet solution was evaluated. Stressed animals with the active behavioral strategy did not respond to oxytocin...

MG-deformations of a surface of positive Gaussian curvature under assignment of variation of any tensor along an edge

D. A. Zhukov

Russian Mathematics > 2017 > 61 > 12 > 13-18

We investigate the infinitesimal MG-deformations of a simply connected surface with positive Gaussian curvature. We choose any symmetric tensor on the surface, variation of the first and the second invariant of this tensor equals given function along a boundary. The study of these boundary-value problems is reduced to the investigation of a solvability of Riemann–Hilbert boundary-value problem and...

Spin-tunneling magnetoresistive elements based on multilayered nanostructures

V. V. Amelichev, P. A. Belyakov, D. V. Vasil’ev, D. A. Zhukov, more

Technical Physics > 2017 > 62 > 8 > 1281-1283

The results of studies of characteristics of spin-tunneling magnetoresistive (STMR) elements fabricated from multilayered nanostructures using a mask technique have been considered. The parameters of magnetic annealing of STMR elements have experimentally been obtained. The results of these experiments have shown that a magnitude of the magnetoresistive effect can increase by four to five or more...

Influenza vaccination in healthy working adults in Russia

O. Yu At’kov, A. V. Azarov, D. A. Zhukov, N. Nicoloyannis, more

Applied Health Economics and Health Policy > 2011 > 9 > 2 > 89-99

Background All age groups are affected by influenza infection, resulting in significant medical and economic burden. Influenza infection of healthy working adults can have a marked effect on companies due to lost work days and reduced productivity. Studies in corporate settings have shown that vaccination programmes reduce this burden, although there is a lack of data in Eastern European countries...

The Effects of Stages of the Estrous Cycle on Pain Thresholds in Female White Rats

E. P. Vinogradova, D. A. Zhukov, A. S. Batuev

Neuroscience and Behavioral Physiology > 2003 > 33 > 3 > 269-272

The effects of stages in the estrous cycle on electrical pain thresholds were studied in white rats in conditions of chronic measurement. On recording day 3, females in the diestrus and estrus stages showed sharp increases in shudder and paw-shuffling thresholds. Females in proestrus and metestrus showed no change in thresholds as compared with those in the first days of recording. Starting from day...

Effect of Escapable and Inescapable Stress on Levels of Catecholamines in Adrenals and Corticosterone in Blood Plasma in Young and Aged Rats

E. D. Bazhanova, D. A. Zhukov, S. Porta, O. A. Danilova

Journal of Evolutionary Biochemistry and Physiology > 2002 > 38 > 2 > 234-238

Effect of escapable and inescapable electrical stress (ES, IS) on the catecholaminergic system was studied in young (3 months) and aged (25 months) male Wistar rats on the day 3 after stress, using radioimmune analysis and high-pressure liquid chromatography. Catecholamine concentration in adrenals and corticosterone level in blood of control aged rats was lower than in young animals. On the third...
