Comorbid diseases in patients with colon polyps in the practice of the district physician

An important problem in the prevention of colon cancer is the timely diagnosis and treatment of polyps. For today it is extremely important to determine the effect of comorbid diseases on the occurrence and development of tumors of the colon. The aim of the study was to find the connection of colon polyps with comorbid diseases. 82 people were surveyed on the basis of the Tyumen state medical University of Minzdrav of Russia and of SAHI 'municipal clinic №3' Tyumen. All patients were divided into two groups: with colon polyps and without colon polyps and a comparative analysis of comorbid diseases in the groups. The following results are obtained. Among comorbid diseases in the group with colon polyps were significantly more frequent than in the group without colon polyps: elevated cholesterol, erosive gastritis and cholecystectomy, from concomitant diseases – arterial hypertension. Conclusions. Patients with elevated cholesterol levels, as well as with erosive gastritis and after cholecystectomy should be directed to colonoscopy - as a screening study.Важной проблемой профилактики рака толстой кишки является своевременная диагностика и лечение полипов. На сегодняшний день является крайне актуальным определение влияния коморбидных заболеваний на возникновение и развитие новообразований толстой кишки. Целью исследования явилось найти связь возникновения полипов толстой кишки с коморбидными заболеваниями. Обследовано 82 человека на базе ФГБОУ ВО Тюменский ГМУ Минздрава России и ГАУЗ ТО «Городская поликлиника №3» г. Тюмень. Все больные разделены на две группы: с полипами толстой кишки и без полипов толстой кишки и проведен сравнительный анализ коморбидных заболеваний в группах. Получены следующие результаты. Среди коморбидных заболеваний в группе с полипами толстой кишки достоверно чаще, чем в группе без полипов толстой кишки встречались: повышенный уровень холестерина, эрозивные гастриты и холецистзктомия, из сопутствующих заболеваний - артериальная гипертензия. Выводы. Пациенты с повышенным уровнем холестерина, а так же с эрозивными гастритами и после холецистэктомии должны быть направлены на колоноскопию - как скрининговое исследование

The morphological and structural features of ferrite compositions (1-x) MeFe2O4 xP2O5 prepared by plasma spraying

Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.Structural features of spinel ferrites formed by rapid quenched from the liquid state, has been studied. It was found that higher quenching rates cause sequential disorder of the spinel structure. Process starts with statistically uniform redistribution of cations at lattice points, then collapse of the anionic frame leads to the topological disorder. This process results in formation of the thermodynamically unstable cluster state and heating of these hardened ferrites leads to a stepwise release of energy. Therefore the described process improves activity of ferrite powders in solid-phase and catalytic reaction

Magnetic and resonant properties of ferrite compositions (1−x) MeFe2O4 • xP2O5 prepared by plasma spraying

Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.Abstract It was found that after plasma spraying and rapid quenching of ferrite compositions (1 − x) MeFe2O4 · xP2O5 within the range of 0.35 < x < 0.4 for any considered compounds, transition to the x-ray-amorphous state is observed (so called concentration depended transition (CDT). This transition occurs along with modification of x-ray and Mössbauer spectra (quadrupole splitting into isomer shift) and changing their magnetic parameters: a saturation magnetization σs, a coercive field Hc and a line width of ferromagnetic resonance (FMR) ΔH. The abnormal increase of saturation magnetization σs is revealed at Т < 100 K. Particularities of changing the Curie temperature Tc and a saturation magnetization σs at different rates of quenching ferrites from the liquid state are discussed

MINIMUM TiB2 CONTENT IN A COMPOSITE CATHODE WETTED WITH ALUMINUM

Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.The minimum content of functional component (titanium borideTiB2) in cathodic refractory material that provides wetting with molten aluminum is substantiated. It is established that total cathode wetting with aluminum is observed with some minimum content of TiB2 in a powder composite (16 – 18 vol.%), when according to occurrence theory there is formation of an “infinite cluster”, i.e., a bonded percolation network of titanium boride particles. The volume of wetted composite containing a fixed amount (for example, 1 kg) of TiB2 does not depend on its phase composition and porosity, but is determined by the diboride volume content. A TiB2 content in the range 18 – 20 vol.% should be considered the optimum that creates reliable continuous wetting of a composite surface
