Role of foreign language teacher shaping students’ research skills

© 2015 Canadian Center of Science and Education. All rights reserved. Nowadays many foreign language teachers are not enough aware about the significance of the research component within their profile discipline, arguing that students even in their native language do not have enough use of fundamentals in their scientific professional activities. Therefore, this article is aimed to study the role of foreign language teacher when mastering students’ research skills in the process of learning English as a foreign language. The study results have confirmed that process of mastering students’ research skills when learning foreign language is directly connected with their teacher’s own research skill level. These article materials have practical value both for foreign language teachers and for students enrolled for foreign languages programs of education sciences faculties at high schools

Liposomal streptokinase (a mixture of free (66.3  %) and entrapped (23.7  %) drug) with a diameter of ~60 nm was prepared. The analysis of the D-dimers formation kinetics in the dog’s blood plasma showed that the liposomal streptokinase hada prolonged effect up to 180 minutes.Получены липосомы со стрептокиназой с размерами ~60 нм, представляющие собой смесь, состоящую из свободного (66,3  %) и связанного (23,7  %) препарата. На основании анализа кинетики образования Д-димеров в плазме крови собак установлено, что липосомальная форма стрептокиназы обладает пролонгированным эффектом в течение 180 мин

Выделение, характеристика и молекулярно-генетическая идентификация нового штамма бактерий Paenibacillus species

Bacterial variant PS-K-17 was isolated from wheat grain contaminated by polysaccharide-producing microbiota for further characterization. It was found that the isolate grown on agar slants and in submerged culture on media with specific substrates synthesized beta-galactosidase, amylase, protease, pectinase, cellulase, beta-glucanase, lipase (esterase), alginase, extracellular polysaccharides, and pigments, probably carotenoids. Based on cultural-morphological and physiological-biochemical properties and phylogenetic analysis of nucleotide sequences of 16S rRNA gene (access code MF443394 in GenBank) the bacterial culture was identified as Paenibacillus species PS-K-17. The studied isolate forms one phylogenetic branch with type strains Paenibacillus nicotianae (98.3 %), Paenibacillus hordei (98.2 %), Paenibacillus kyungheensis (97.9 %), holding wherein a separate position. Strain Paenibacillus sp. PS-K-17 may find use in biotechnology as a producer of extracellular polysaccharides and enzymes splitting plant polymeric substances as well as a component of microbial consortium-ingredient of a new complex feed additive.Из зерна пшеницы, контаминированного образующей полисахарид микрофлорой, выделена и охарактеризована культура бактерий ПС-К-17. Установлено, что изолят на агаризованных средах и в глубинной культуре со специфическими субстратами синтезирует бета-галактозидазу, амилазу, протеазу, пектиназу, целлюлазу, бета- глюканазу, липазу (эстеразу), альгиназу, а также внеклеточные полисахариды и пигменты, возможно, каротиноиды. На основании культурально-морфологических и физиолого-биохимических особенностей, а также филогенетического анализа нуклеотидных последовательностей гена 16S рРНК (код доступа MF443394 в GenBank) бактериальная культура идентифицирована как Paenibacillus species ПС-К-17. Исследуемый изолят образует одну филогенетическую ветвь с типовыми штаммами Paenibacillus nicotianae (98,3 %), Paenibacillus hordei (98,2 %), Paenibacillus kyungheensis (97,9 %), в пределах которой занимает обособленное положение. Штамм Paenibacillus sp. ПС-К-17 может найти применение в биотехнологии как продуцент внеклеточных полисахаридов и ферментов, расщепляющих растительные полимеры, а также как компонент микробного консорциума в составе новой кормовой добавки комплексного действия

Изучение полиморфизма генов R2R3 Myb транскрипционных факторов культур семейства Solanaceae и гена Myb114 рода Brassica в связи с регуляцией биосинтеза антоцианов

Based on comparison of R2R3 Myb genes in Solanaceae (S. lycopersicum: Ant1, Ant2, S. melongena: Myb1, C. annuum: Myb113-like1 and Myb113-like2) and Brassicaceae crops, a search for orthologous sequences was The sequences encoding Myb114 TF in Brassica oleracea and Brassica rapa was found to be the closest in a nucleotide structure to the previously investigated genes in Solanaceae. Тhе polymorphism in the promoter region of the Capsicum annuum Myb113-like1 gene that regulates anthocyanin biosynthesis: an additional 148 bp repeat and 2(1) bp insertion in the forms with impaired anthocyanin synthesis in fruits was studied. A relationship between the presence of an insert in the promoter (Myb113-like1pr+148) and polymorphisms in the exon regions of Myb113-like1delTand Myb113-like2C/Аgenes associated with impaired anthocyanin synthesis was established. A number of polymorphisms of the Myb114 gene in vegetable crops of the cabbage family (Brassica oleracea, Brassica rapa), which closely correlate with high/low accumulation of anthocyanins in leaves, were identified. In B. oleracea, SNPs that lead to the replacement of two amino acids located in the region of DNAbinding domains were found, which leads to a change in the efficiency of binding of this transcription factor and the promoters of structural biosynthesis genes. A protein sequence encoded by the Myb114 gene in accessions of the leafy turnip (B. rapa) with a high accumulation of anthocyanins in the leaves differed from the accessions without anthocyanin accumulation in the leaves by five amino acids, while the regions of DNA-binding domains were the same in the forms with various anthocyanin accumulation.На основе сравнения генов R2R3 Myb транскрипционных факторов у овощных пасленовых (S. lycopersicum: Ant1, Ant2, S. melongena: Myb1, C. annuum: Myb113-like1 и Myb113-like2) и капустных культур выполнен поиск ортологичных последовательностей. Выявлены наиболее близкие по нуклеотидной структуре к ранее изученным генам у пасленовых последовательности, кодирующие Myb114 ТФ у Brassica oleracea и Brassica rapa. Изучен полиморфизм в промоторной области гена Myb113-like1 Capsicum annuum, регулирующего биосинтез антоцианов: дополнительный повтор размером 148 п. н. и вставка 2 (1) п. н. у форм с нарушенным синтезом антоцианов в плодах. Установлена связь между наличием вставки в промоторе (Myb113-like1pr+148) с полиморфизмами в экзонных областях генов Myb113-like1delT и Myb113-like2C/А, связанными с нарушением синтеза антоцианов. Выявлен ряд полиморфизмов гена Myb114 у овощных культур семейства капустных (Brassica oleracea, Brassica rapa), тесно коррелирующих с высоким/низким накоплением антоцианов в листьях. У B. oleracea выявлены SNP, которые ведут к замене двух аминокислот, расположенных в области ДНК-связывающих доменов, что приводит к изменению эффективности связывания данного транскрипционного фактора с промоторами структурных генов биосинтеза. Белковая последовательность, кодируемая геном Myb114, у образцов B. rapa разновидности репа листовая с высоким накоплением антоцианов в листьях отличалась от таковой у образцов с отсутствием антоцианов в листьях пятью аминокислотами, при этом области ДНК-связывающих доменов были одинаковыми у форм с различным накоплением антоциана

Unusual noble gas compositions in polycrystalline diamonds: preliminary results from the Jwaneng kimberlite, Botswana

We have undertaken noble gas analyses of four polycrystalline framesite diamonds from the Jwaneng kimberlite pipe, Botswana. These samples yielded complex, multiple noble gas components (crustal, atmospheric and in situ radiogenic/fissiogenic), which were successfully deconvoluted by combining vacuum crushing and step-heating experiments and examining a full suite of noble gas isotope and elemental abundances. The most striking observation is the presence of crustal nucleogenic neon, released on graphitisation of the framesites. Neon of this composition can only have been produced in the crust and subsequently incorporated during formation of the framesites in the mantle. This may indicate that noble gases produced in the crust, such as nucleogenic neon and possibly xenon, and some radiogenic 4He and 40Ar and fissiogenic xenon, were introduced into the subcontinental mantle source during ancient subduction-related processes. If correct, then some parts of the mantle may contain significant quantities of crustal noble gases
