Syktyvkar, Russia

Syktyvkar State University is the principal university in Syktyvkar, the capital of the Komi Republic in Russia. It was founded in 1972 and has over 3,500 full-time students and 250 faculty members.During the fall and winter 2007-2008, Syktyvkar State University was selected to host the Associate Regional Office of Undergraduate Studies for Russia of the University of the Arctic.The university is associated with the Russian Mineralogical Society.The Huazhong University of Science & Technology rates the university as 98th among Russian universities.In March 2009 the university established the Sorokin Research Center to undertake research and publication of archive materials on the sociologist Pitirim Sorokin from international sources, mainly from the Sorokin's special collection at the University of Saskatchewan in Canada.

The exocyclic ring of methylpheophorbide a{cyrillic} was subjected to hydroxymethylation under Tollens reaction conditions. Some distinctions of the stereochemistry of this reaction were observed, compared to other condensation reactions involving this exocyclic ring. © ISUCT Publishing. Source

Method of symmetric polynomials (MSP) is developed to calculations of high powers of matrices. It is based on the new type of recurrence relations between symmetric polynomials of n-th order. New algorithm for computation j-th power of matrix of order n is compared with methods of ordinary multiplication and repeated squaring of matrix. Dependencies of comparative effectiveness R of the new method from power j and order n of matrix are investigated. Computation matrix M2j by MSP is more effective and accurate than the method of repeated squaring of matrix if j > n, and with increasing j comparative effectiveness R tends to n/2. © 2015 IEEE.

Transformation of meadow communities under the impact of hay harvesting and livestock grazing has been studied in the floodplains of the Vychegda and Pechora rivers. Changes in the floristic composition, structure, and productivity of meadows have been evaluated using synanthropization and adventization indices. On this basis, meadow phytocenoses at three different stages of pasture digression have been distinguished. © 2014 Pleiades Publishing, Ltd. Source

Most age-related diseases and aging itself are associated with chronic inflammation. Thus pharmacological inhibition of inflammatory processes may be effective antiaging strategy. In this study we demonstrated that treatment of Drosophila melanogaster with 10 non-steroidal anti-inflammatory drugs (NSAIDs: CAY10404, aspirin, APHS, SC-560, NS-398, SC-58125, valeroyl salicylate, transresveratrol, valdecoxib, licofelone) leads to extension of lifespan, delays age-dependent decline of locomotor activity and increases stress resistance. The effect of the lifespan increase was associated with decrease of fecundity. Depending on the concentration, NSAIDs demonstrated both anti- and pro-oxidant properties in Drosophila tissues. However, we failed to identify clear correlation between antioxidant properties of NSAIDs and their pro-longevity effects. The lifespan extending effects of APHS, SC-58125, valeroyl salicylate, trans-resveratrol, valdecoxib, and licofelone were more pronounced in males, valdecoxib and aspirin - in females. We demonstrated that lifespan extension effect of NSAIDs was abolished in flies with defective genes involved in Pkh2-ypk1-lem3-tat2 pathway. Source
