Features of the distribution of the concentration on the mucous stomach of active and inactive forms of helicobacterial infection in patients with chronic non-atrophic gastritis, suffering and not suffering from chronic constipation

The frequency of detection and the degree of colonization of the gastric mucosa by the active and inactive form of Helicobacter pylori infection was analyzed in 50 patients with chronic non-atrophic gastritis, suffering from chronic constipation, and in 50 patients with chronic non-atrophic gastritis, who did not suffer from constipation. In the group of patients suffering from chronic constipation, the frequency of occurrence of the active form of Helicobacter pylori infection in different topographic zones of the stomach ranged from 46% to 56% with an average degree of mucosal seeding from 1.12 ± 0.13 (+) to 1.48 ± 0.13 (+), the frequency of occurrence of an inactive form of Helicobacter pylori infection in different topographic zones of the stomach ranged from 0% to 48% with an average degree of mucosal colonization from 0 ± 0.0 (+) to 1.30 ± 0.13 (+), while while in the group of patients who did not suffer from chronic constipation, the frequency of occurrence of an act distinct Helicobacter pylori infection in different topographic zones of the stomach ranged from 36% to 52% with an average degree of mucosal seeding from 1.02 ± 0.13 (+) to 1.34 ± 0.13 (+), and the frequency of occurrence of the inactive Helicobacter pylori infections in different topographic zones of the stomach ranged from 0% to 58% with an average degree of mucosal seeding from 0 ± 0.0 (+) to 1.56 ± 0.13 (+). In patients of the first group, the frequency of detection of intracellular "depots" of HP infection was 2.3 times higher than in patients of the second group

Analysis of the recultivation effectivity performed after gas industrial complex accidental impact

The current state of the agro-industrial complex of Ukraine is characterized by the increase of technogenic impact on the environment, especially in emergency situations. The state of soil and groundwater was determined for the terrain affected by technogenic disaster and where subsequent recultivation took place. A comparison with the state of the soil and water of the “ecologically clean” settlement of the same district was carried out. Conclusions on the effectiveness of the recultivation measures have been made

Production of spectator hypermatter in relativistic heavy-ion collisions

We study the formation of large hyper-fragments in relativistic heavy-ion collisions within two transport models, DCM and UrQMD. Our goal is to explore a new mechanism for the formation of strange nuclear systems via capture of hyperons by relatively cold spectator matter produced in semi-peripheral collisions. We investigate basic characteristics of the produced hyper-spectators and evaluate the production probabilities of multi-strange systems. Advantages of the proposed mechanisms over an alternative coalescence mechanism are analysed. We also discuss how such systems can be detected taking into account the background of free hyperons. This investigation is important for the development of new experimental methods for producing hyper-nuclei in peripheral relativistic nucleus-nucleus collisions, which are now underway at GSI and are planned for the future FAIR and NICA facilities.Comment: 28 pages, including 10 figures.

Magnus force and acoustic Stewart-Tolman effect in type II superconductors

At zero magnetic field we have observed an electromagnetic radiation from superconductors subjected by a transverse elastic wave. This radiation has an inertial origin, and is a manifestation of the acoustic Stewart-Tolman effect. The effect is used for implementing a method of measurement of an effective Magnus force in type II superconductors. The method does not require the flux flow regime and allows to investigate this force for almost the whole range of the existence of the mixed state. We have studied behavior of the gyroscopic force in nonmagnetic borocarbides and Nb. It is found that in borocarbides the sign of the gyroscopic force in the mixed state is the same as in the normal state, and its value (counted for one vortex of unit length) has only a weak dependence on the magnetic field. In Nb the change of sign of the gyroscopic force under the transition from the normal to the mixed state is observed.Comment: 4 pages, 5 figure

Peculiarities of pathogenesis of gastric cancer formed in the treatment of chronic non-atrophic gastritis by proton pump inhibitors

The data on the duration of use of proton pump inhibitors, the nature and duration of stress, and the timing of the first clinical and instrumentally confirmed manifestations of gastric cancer in 10 patients with chronic non-atrophic gastritis who were treated with proton pump inhibitors both in the form of monotherapy and the composition of standard regimens of H. pylori therapy. It was found that the duration of taking proton pump inhibitors ranged from 2 days to 2 months, and the duration of stress - from 2 years to 45 years. The first clinical manifestations occurred from the 1st to the 5th month after the end of the treatment, and the deterioration of the patients' condition proceeded quickly, “avalanche-like” within 7-10 days

Characteristics of the electric field accompanying a longitudinal acoustic wave in a metal. Anomaly in the superconducting phase

The temperature dependence of the amplitude and phase of the electric potential arising at a plane boundary of a conductor when a longitudinal acoustic wave is incident normally on it is investigated theoretically and experimentally. The surface potential is formed by two contributions, one of which is spatially periodic inside the sample, with the period of the acoustic field; the second is aperiodic and arises as a result of an additional nonuniformity of the electron distribution in a surface layer of the metal. In the nonlocal region the second contribution is dominant. The phases of these contributions are shifted by approximately \pi /2. For metals in the normal state the experiment is in qualitative agreement with the theory. The superconducting transition is accompanied by catastrophically rapid vanishing of the electric potential, in sharp contrast to the theoretical estimates, which predict behavior similar to the BCS dependence of the attenuation coefficient for a longitudinal sound.Comment: 9 pages, 6 figure
