В данной статье изложены результаты исследования частот встречаемости однонуклеотидных полиморфизмов генов ADD1α (1378 G>T), AGT (704 T>C и 521 C>T), AGTR1 (1166 A>C) и AGTR2 (1675 G>A) у различных этнических групп жителей арктической зоны, страдающих эссенциальной артериальной гипертензией. для обнаружения вышеупомянутых полиморфизмов был использован метод ПЦР в режиме реального времени с детекцией температуры плавления дуплексов. В ходе исследования статистически значимые (p ≤ 0,05) различия между исследуемыми группами были выявлены по точкам ADD1α 1378 G>T; AGT 521 C>T и AGTR1 1166 A>C.
The article presents the results of the study of the frequencies of occurrence of single nucleotide polymorphisms of the genes ADD1α (1378 G> T), AGT (704 T> C and 521 C> T), AGTR1 (1166 A> C) and AGTR2 (1675 G> A) groups of residents of the Arctic zone of the RS (Ya), suffering from essential arterial hypertension. To reveal the above mentioned polymorphisms, a real-time PCR method was used with detection of the melting temperature of duplexes. In the course of the study statistically significant differences between the study groups were identified by the points ADD1α 1378 G> T; AGT 521 C>T and AGTR1 1166 A> C.

Введен сравнительный анализ психоэмоциональных особенностей лиц, проживающих в полярных, субполярных и средних широтах, принимающих участие в многоширотном мониторинге, в зависимости от наличия у них психологической чувствительности к действию гелиогеомагнитных факторов. Установлено, что добровольцы, проживающие как в северных (полярных и субполярных), так и в средних широтах, имели ряд сходных черт, в зависимости от наличия психологической чувствительности к действию гелиогеофизических факторов (стремление анализировать проблемы, подавлять эмоции, доброжелательность, целеустремленность). Результаты данного исследования позволят осуществлять персонифицированный подход профилактики психосоматических заболеваний и невротических состояний у относительно здоровых лиц с учетом наличия у них психологической чувствительности к изменениям гелиогеомагнитной возмущенности, а также в зависимости от широты их проживания.
The article presents a comparative analysis of psycho-emotional peculiarities of persons from polar, sub-polar and middle latitudes, taking part in multiple-latitude monitoring, in relation to a psychological sensitivity to heliogeomagnetic factors. It is found that the volunteers, living both in northern (polar and sub-polar) and middle latitudes, have a number of similarities depending on a psychological sensitivity to heliogeophysical factors (tending to analyze problems, emotional suppression, agreeableness, purpose). The findings of the study allow organizing patient-specific preventive methods for psycho-somatic diseases and neuroticisms in relatively healthy persons taking into consideration their psychological sensitivity to changes in heliogeomagnetic activity, and the latitude of their place of living.

Large-amplitude morning Pc5 magnetic pulsations during the main phase of intense magnetic storm were registered at magnetic stations of 190-200° magnetic meridians on January 21-22, 2005. Magnetic pulsations in the Pc5 frequency range observed at the GOES 10, 12 satellites in the noon and evening sectors exhibited a high degree of magnetic compessibility. A Los Alamos particle detector on board geostationary satellite observed the occurrence of energetic particle flux oscillations in the Pc5 band. The Pc5 pulsations were followed with the VLF-emission and riometer absorption modulation with the same period. The regions of maximal amplitude of Pc5 geomagnetic pulsations and deep modulation of riometer absorptions shifted to high latitudes in the same way. Significant and long-lasting compression of magnetosphere led, probably, to moderate pitch-angle diffusion of particle into the loss cone even at the middle latitudes. Analysis of coordinated data allowed us to suggest that a modulation effects of precipitating particles are caused by a compressional waves.

The Jupiter is a powerful regular source of high-energy electrons (0,2-40 MeV). In this connection their density in the near-Earth space systematically increases with a period of 399 days, which is coincident with the synodic period of Jupiter. According to our estimations, their energy is sufficient to produce a significant local reduction of the magnetic field in the IMF sector connected with the Jupiter. In this paper the evidence is presented that the electron fluxes in the Jovian sector are controlled by the general magnetic field of the Sun. A treatment of 399-day intervals of the electron fluxes and IMF, obtained from spacecraft data for the period of 1963 to 2000 has been performed by superposed epoch technique taking into account the periodic change of the solar magnetic field polarity. Having adopted the Jupiter opposition day to be an epoch zero, the changes in particle intensity and IMF components under different signs of the general magnetic field of the Sun are found by using a large dataset (9925 days). The times of 399-day variation maxima in different periods of solar activity are compared and a character of their displacement relative to Jupiter opposition momentsis discussed.

Examination of auroral absorption (AA) occurrence rate and AA meridional distribution versus local time and in the course of the solar cycle has been performed by riometer observations from 1985 to 1995 at the longitude of Yakutsk. Geomagnetic latitude of the region of absorption maximum occurrence changes in the course of the solar cycle from 66.5° to 64.4°. The largest displacement of this region to lower latitudes is observed during years of maximum solar activity. The half-width of the region is ~8° at solar minimum and ~10° at solar maximum. It has been also revealed that the region of AA is shifted to higher latitudes at daytime (1000-1400LT), and to lower ones in the evening (1800-2000LT), the displacement from the daily average position being ~1° and ~3° in the years of solar activity maximum and minimum, respectively. In all years at 2000-2100LT a short-term extension of the AA region by 1-4° is observed. The interpretation of the observationa is proposed.

From data of riometer observations from 1986 to 1993 at stations of Kotelny Island, Tixie Bay and Zhigansk the semi-diurnal variations of occurrence frequency of auroral absorption and their dependence on geomagnetic activity have been determined. It has been found that the phase of semi-diurnal variation maximum is systematically shifted to earlier hours with the rise of geomagnetic disturbance. The reason of this experimental fact is discussed.

Galactic cosmic ray (GCR) diffusion in interplanetary space depends in a certain way on the degree of regularity of the interplanetary magnetic field (IMF). The sector IMF structure is manifested in inhomogeneous GCR distribution in the heliosphere. In parallel with the usual sectors associated with solar activity, one should take into account the sectors, which are caused by the Jupiter activity. It is known that the Jupiter is a powerful regular source of high-energy electrons (0.2-40 MeV), the density of which, on the average, is many times higher than that of solar cosmic rays. The high-energy electrons are systematically registed with the 399-day period in the near-Earth space. According to estimations of the particle energy density their flux is sufficient to decrease the magnetic field in the Jovian sector and can due to corresponding large-scale inhomogeneity in the GKL distribution. Hereby, we present the evidences that the GCR diffusion is noticeably stronger in the sector where there are Jovian electrons. By data on periodic passage of those sectors near the Earth, we have treated neutron monitor data using the superposed epoch technique. The day of the Earth and Jupiter opposition is taken as a zero epoch. At large statistical data (9925 days) it is found that the GCR intensity in that period increases with an amplitude near 1%. The groud effect is manifested with the period of 399 days and its maximum time is in a certain way shifted relative to the planet opposite moment.
