Long-term impact of fecal transplantation in healthy volunteers

Fecal microbiota transplantation (FMT) has been recently approved by FDA for the treatment of refractory recurrent clostridial colitis (rCDI). Success of FTM in treatment of rCDI led to a number of studies investigating the effectiveness of its application in the other gastrointestinal diseases. However, in the majority of studies the effects of FMT were evaluated on the patients with initially altered microbiota. The aim of our study was to estimate effects of FMT on the gut microbiota composition in healthy volunteers and to monitor its long-term outcomes.Peer ReviewedPostprint (published version

Вакцинопрофилактика пневмококковой инфекции у детей

Pneumococcal infection remains one of the leading reasons for infant mortality from vaccine-preventable infections. Today vaccination is the most effective way to prevent diseases caused by antibiotic-resistant pneumococci. In the article, authors present current approaches to vaccinal prevention of pneumococcal diseases. The plan of action for carrying out active immunoprophylaxis of pneumococcal infection is explained in detail for both healthy children and patients from risk groups for severe pneumococcal diseases development. The published work is based on key points of the guidelines of the Ministry of Health of the Russian Federation on vaccinal prevention of pneumococcal infection (developed and approved by the professional association of pediatricians «The Union of Pediatricians of Russia»).Пневмококковая инфекция остается одной из ведущих причин детской смертности от вакциноуправляемых инфекций. Вакцинация на сегодняшний день является наиболее эффективным направлением профилактики заболеваний, вызываемых устойчивыми к антибактериальным препаратам пневмококкам. В статье коллективом авторов представлены актуальные подходы к вакцинопрофилактике болезней пневмококковой этиологии. Подробно разъяснен алгоритм действий при проведении активной иммунопрофилактики пневмококковой инфекции как здоровых детей, так и пациентов из групп риска по развитию тяжелых форм пневмококковых заболеваний. Публикация основана на ключевых позициях методических рекомендаций Министерства здравоохранения РФ по вакцинопрофилактике пневмококковой инфекции (разработанных и утвержденных профессиональной ассоциацией детских врачей «Союз педиатров России»).КОНФЛИКТ ИНТЕРЕСОВАвторы статьи подтвердили отсутствие конфликта интересов, о котором необходимо сообщить

Rewriting Chaucer: Some Dimensions of Middle English - Modern English translation

В статье анализируется перевод «Кентерберийских рассказов» Дж. Чосера на современный английский язык с целью определения основных параметров среднеанглийского текста, обусловливающих необходимость диахронического перевода, и уточнения основных направлений «модернизации» текста оригинала.The paper analyses a modern English translation of Geoffrey Chaucers The Canterbury Tales to determine the major features of the Middle English text which justify diachronic translation and to define the lines along which the translator modernizes the text

Formation of CuxAu1−x phases by cold homogenization of Au/Cu nanocrystalline thin films

It is shown, by using depth profiling with a secondary neutral mass spectrometer and structure investigations by XRD and TEM, that at low temperatures, at which the bulk diffusion is frozen, a complete homogenization can take place in the Cu/Au thin film system, which leads to formation of intermetallic phases. Different compounds can be formed depending on the initial thickness ratio. The process starts with grain boundary interdiffusion, which is followed by a formation of reaction layers at the grain boundaries that leads to the motion of the newly formed interfaces perpendicular to the grain boundary plane. Finally, the homogenization finishes when all the pure components have been consumed. The process is asymmetric: It is faster in the Au layer. In Au(25nm)/Cu(50nm) samples the final state is the ordered AuCu3 phase. Decrease of the film thicknesses, as expected, results in the acceleration of the process. It is also illustrated that changing the thickness ratio either a mixture of Cu-rich AuCu and AuCu3 phases (in Au(25nm)/Cu(25nm) sample), or a mixture of disordered Cu- as well as Au-rich solid solutions (in Au(25nm)/Cu(12nm) sample) can be produced. By using a simple model the interface velocity in both the Cu and Au layers were estimated from the linear increase of the average composition and its value is about two orders of magnitude larger in Au (ca. 10−11 m/s) than in Cu (ca. 10−13 m/s)
