Sustainment of High-Beta Mirror Plasma by Neutral Beams

The report presents two experiments carried out in Budker Institute for obtaining the maximum plasma beta (ratio of the plasma pressure to magnetic field pressure) in axially symmetric magnetic field. The experiments are based on injection of powerful focused neutral beams with high neutral power density in the plasma. The produced fast ion population significantly increases the plasma pressure. It the axially symmetric GDT experiment (Gas Dynamic Trap) the plasma beta exceeded 0.6 at the fast ion turning points. The CAT experiment (Compact Axisymmetric Toroid) is being prepared for obtaining a plasmoid with extremely high diamagnetism in axially symmetric magnetic field. Reversal of magnetic field in the plasmoid is possible in this experiment

The investigation of absolute proper motions of the XPM Catalogue

The XPM-1.0 is the regular version of the XPM catalogue. In comparison with XPM the astrometric catalogue of about 280 millions stars covering entire sky from -90 to +90 degrees in declination and in the magnitude range 10^m<B<22^m is something improved. The general procedure steps were followed as for XPM, but some of them are now performed on a more sophisticated level. The XPM-1.0 catalogue contains star positions, proper motions, 2MASS and USNO photometry of about 280 millions of the sources. We present some investigations of the absolute proper motions of XPM-1.0 catalogue and also the important information for the users of the catalogue. Unlike previous version, the XPM-1.0 contains the proper motions over the whole sky without gaps. In the fields, which cover the zone of avoidance or which contain less than of 25 galaxies a quasi absolute calibration was performed. The proper motion errors are varying from 3 to 10 mas/yr, depending on a specific field. The zero-point of the absolute proper motion frame (the absolute calibration) was specified with more than 1 million galaxies from 2MASS and USNO-A2.0. The mean formal error of absolute calibration is less than 1 mas/yr.Comment: 11 pages, 9 figures, accepte

The article identified the necessary competences in the field of innovative entrepreneurship (professional, business, functional, social and communicative), as well as entrepreneurial qualities (integrity, credibility, intelligence, presence of imagination, ability to make decision, ability to organize control, to provide justification of decisions); the methodology of students’ gradual of entrepreneurial competences is developed; factors blocking the effectiveness of the students’ entrepreneurial competences’ formation are revealed

Morphological changes of the gastric mucosa in patients with duodenogasric reflux: relationship with acidity and helicobacter pylori

Purpose: to reveal the peculiarities of the duodenogastric reflux (DGR) impact on acidity and morphological features of the gastric mucosa in patients with "primary" reflux gastritis, as well as in cases of reflux gastritis in combination with H. pylori. Methods: 66 patients with chronic reflux gastritis were examined, 15 people formed a control group. All patients had gastric endoscopy with determination of the gastric acidity and concentration of bile acids. Biopsy material for histological examination was obtained from 55 patients, in 12 cases of suspected intestinal metaplasia additional histochemical (PAS and alcian blue) and immunohistochemical (cytokeratin 20, Villin, carcinoembriogenic antigen, MUC2, CD45) assays were performed. Results: the level of acidity in patients with DGR was higher (pH = 3.55 ± 2.3) compared to the control group (pH = 6.85 ± 1.34). Cases of DGR differed from the control group regarding the mononuclear infiltration (p=0,001), foveolar hyperplasia (p=0,001) in both antral and fundic parts of the stomach, mucosal edema (p=0,022) and atrophy (p=0,02) at the level of the antrum, and intestinal metaplasia (p=0,022) at the level of the body. In the presence of H. pylori infection, in addition to the abovementioned signs, infiltration by cells of acute inflammation (p = 0.005) was detected, which indicates an increase in the damaging effect of H. pylori infection in DGR. Conclusion: DGR may lead to "oxidation" of gastric contents. The effect of DGR leads to intestinal metaplasia of the body and atrophy of the antral part of stomach, chronic inflammation and foveolar hyperplasia. The presence of H. pylori boosts the morphological changes in the gastric mucosa caused by DGR.Цель: выявить характер воздействия дуоденогастрального рефлюкса (ДГР) на морфологические показатели слизистой оболочки желудка при «первичном» рефлюкс-гастрите, в том числе, в сочетании с H.pylori, исследовать связь ДГР с уровнем кислотности. Материалы и методы: обследовано 66 пациентов с рефлюкс-гастритом, 15 человек составили группу контроля. Всем пациентам проведена эзофагогастродуоденоскопия с определением кислотности и концентрации желчных кислот в желудочном содержимом. 55 пациентам проведено гистологическое обследование биопсийного материала слизистой оболочки желудка, при наличии признаков кишечной метаплазии 12 пациентам проведено дополнительное гистохимическое (окраска Шифф-йодной кислотой и альциановым синим) и иммуногистохимическое (определение экспрессии цитокератина 20, виллина, MUC2, ракового эмбрионального антигена, CD45) исследование. результаты: Уровень кислотности у пациентов с ДГР был выше (рН=3,55±2,3) по сравнению с группой контроля (рН=6,85±1,34). Из морфологических признаков при дГр значимо отличались от группы контроля мононуклеарная инфильтрация (р=0,001), фовеолярная гиперплазия (р=0,001) в обоих отделах желудка, отек (р=0,022) и атрофия (р=0,02) антрального отдела, кишечная метаплазия (р=0,022) на уровне тела желудка. При наличии инфекции H. pylori, помимо уже выявленных признаков, выявляется инфильтрация клетками острого воспаления (р=0,005), что свидетельствует об усилении повреждающего действия инфекции H. pylori при ДГР. Выводы: Воздействие ДГР приводит к «окислению» желудочного содержимого. Воздействие ДГР приводит к кишечной метаплазии тела и атрофии антрального отдела желудка на фоне хронического воспаления и фовеолярной гиперплазии. Присутствие H. pylori усиливает вызванные ДГР морфологические изменения слизистой оболочки желудка

Исследование терапевтической эффективности тровентола у больных бронхиальной астмой и хронической обструктивной болезнью легких профессионального генеза

Respiratory pathology takes 15 to 35 % of occupational diseases and a half of them falls to chronic obstructive pulmonary disease (COPD) and asthma. The aim of this study was to evaluate clinical efficiency and safety of troventol in workers of rubber industry and other hazardous fields and in agriculture workers suffering from asthma or COPD. The study involved 33 workers of hazardous industries of Moscow and 35 agriculture workers. Methods used included questionnaire, physical examination, spirometry, bronchodilating test, methacholine challenge test, peak flowmetry, measurements of NO in the exhaled air (NOexh) and total IgE level before and after treatment with troventol under the continuing hazardous exposure condition. The daily dose of troventol depended on the severity of the disease and ranged 80 to 240 μg. The therapy with troventol has resulted in improvement of cough from 1.6 to 1.2 score (р ≤ 0.05) and dyspnea from 1.12 to 0.8 (р ≤ 0.04). Asthma attacks ceased in 39.7 % of the workers. Number of the workers having normal Tiffeneau index increased from 36.4 to 48.5 %. Bronchial hyperreactivity reduced. NOexh became normal in 24% of the patients. The drug was generally well tolerated.Среди профессиональных заболеваний патология легких составляет от 15 до 35%, причем на долю хронической обструктивной болезни легких (ХОБЛ) и бронхиальной астмы (БА) приходится половина случаев. Целью исследования явилась оценка клинической эффективности и безопасности тровентола у работников каучукового и других вредных производств и сельского хозяйства, страдающих БА и ХОБЛ. Нами было обследовано 33 рабочих вредных производств Москвы и 35 работников сельского хозяйства. Использовали анкетный скрининг, врачебный осмотр, спирометрию с бронходилатационным тестом, бронхопровокационный тест с метахолином, пикфлоуметрию, определяли оксид азота выдыхаемого воздуха (NOexh) и общий IgE крови до и после лечения тровентолом в условиях продолжения контакта с неблагоприятными факторами. Суточная доза тровентола зависела от тяжести заболевания и составила от 80 до 240 мкг. На фоне терапии тровентолом интенсивность кашля уменьшилась в среднем с 1,6 до 1,2 балла (р ≤ 0,05), одышки — с 1,12 до 0,8 балла (р ≤ 0,04), приступы удушья прекратились у 39,7 % рабочих. Число рабочих с нормальным индексом Тиффно увеличилось с 36,4 до 48,5 %, отмечено уменьшение гиперреактивности бронхов в тесте с метахолином. У 24 % пациентов нормализовался NOexh. Переносимость препарата в целом была хорошей
