Special Meaning

This article is dedicated to one of the patterns in development of Russian colloquialism – reconsideration of the key meaning of casual words through metaphorization and metonymization. The goal of this work consists in examination of the trend inherent to Russian colloquialism throughout its evolution, which consists in transferring the meaning of casual words for their use in the field of term formation, as well as in analysis of this phenomenon from the perspective of a Vietnamese native speaker. The article studies the prerequisites that contribute to active use of the colloquialism in formation of special terminology; describes the process of transformation of the meaning of casual words for creating a new terminological meaning; considers the possibilities of formation of special meaning of casual words using metaphors and metonymy. The theoretical framework of this research is comprised of the works of Russian and Vietnamese linguists on reconsideration of colloquialism in term formation. Terms from the various academic fields served as the material for this research. The scientific novelty lies in interpretation of reconsideration of colloquialism as the most economical method for enriching Russian language vocabulary via potential of lexical unites present therein. Practical significance of this study is substantiated by the fact that the acquired results can be used in preparing special curricula, educational materials on lexicology, as well as in teaching Russian language as foreign to Vietnamese audience.

Transient Receptor

Herein, we report the semisynthetic production of the potent transient receptor potential canonical (TRPC) channel agonist (−)-englerin A (EA), using guaia-6,10(14)-diene as the starting material. Guaia-6,10(14)-diene was systematically engineered in Escherichia coli and Saccharomyces cerevisiae using the CRISPR/Cas9 system and produced with high titers. This provided us the opportunity to execute a concise chemical synthesis of EA and the two related guaianes (−)-oxyphyllol and (+)-orientalol E. The potentially scalable approach combines the advantages of synthetic biology and chemical synthesis and provides an efficient and economical method for producing EA as well as its analogs.

A fast, efficient, simple, eco-friendly, regioselective, controllable and economical method for the bromination of aromatic compounds using AlBr3-Br2 system was invetigated. The direct bromination of anilines and phenols with molecular bromine in solution frequently results in polybromination, and when brominated in the existence of oxidants, they also get oxidized rather than experiencing substitutions and in some cases, require fortification of the amino (-NH2) group.

Siraitia Grosvenorii

The extraction yields of mogroside from Siraitia grosvenorii fruits and limonin from orange (Citrus reticulata Blanco) seeds were compared with different extraction methods, respectively. Maceration extraction, stirring extraction, ultrasonic extraction and flash extraction were used for the extraction. The extraction process was modeled using the concept of thin film which provides the resistance to transfer. The results showed that the maximum yields of mogroside (4.11%) and limonin (0.65%) were obtained by ultrasonic extraction and flash extraction respectively. Owing to its shorter extraction time, flash extraction would be an economical method for the mass production of triterpenes from natural products. The model was found to be fit for the comparison of methods for the extraction and provided good correlation of the data. The model could be mainly used in the practical extraction process.
