The aim of this study is to evaluate the effect of moderate physical exercise and treatment time on the organism’s response to NSC631570. The sensitivity of circulating phagocytes to the drug at different times of day was estimated in in vitro experiments. NSC631570 was administered intravenously to healthy volunteers (eleven men, 23 ± 2 years) in a single therapeutic dose in an inpatient and an outpatient setting. Blood samples were obtained before the drug administration, 30 min after the drug injection and every fourth hour throughout the 24 hour period. Biochemical parameters were determined using the hematological analyzer. Flow cytometry was used to evaluate phagocyte metabolism. Treatment of circulating phagocytes with NSC631570 in vitro resulted in an increase in ROS production along with a decrease in their phagocytic activity, most expressed in the morning time. Drug injection to sedentary persons resulted in pro-inflammatory metabolic polarization of circulating phagocytes. Introduction of NSC631570 to active persons was accompanied by a significant increase in phagocyte endocytosis along with a decrease in the daily mean of ROS generation. Significant oscillation (but in the normal ranges) of urea, creatinine, alanine aminotransferase and aspartate aminotransferase after NSC631570 introduction in the outpatient setting was shown during the day. Physical activity interferes with immunomodulatory action of NSC631570 and abrogates pro-inflammatory shift of circulating phagocytes. Biochemical parameters of blood from patients treated with NSC631570 in the outpatient setting must be interpreted cautiously considering the effect of physical activity on some metabolic biomarkers.

The characteristics, performance and application of membrane electrode based on ion associate of diclofenac with base dye Safranine T are described. The electrode response to diclofenac has the sensitivity of 47 ± 1.0 mV decade(?1) over the range of 5 × 10(?5) to 5 × 10(?2) mol/L at pH 6–12, and the detection limit of 3.2 × 10(?5) mol/L. The electrode is easy assembled at a relatively low cost has fast response time (2–4 s) and can be used for a period up to 3.5 months without any considerable divergence in potential. The proposed sensor displayed good selectivity for diclofenac in the presence of different substances. It was used to determine diclofenac in pharmaceuticals by means of the standard addition method.

The article aims to highlight Russian approaches to Chinese One Belt-One Roadinitiative. It examines possible opportunities and challenges for co-development of theEurasian Economic Union and the Belt project. Both projects and their co-developmentmay reduce the uncertainty in Eurasia, caused by significant structural changes ininternational relations and the world economy, the emergence of new trade regimesand the erosion of leadership in international affairs. Russian interests in this regardare determined by the need for modernization and long-term development, which couldalso help to address acute security issues. These particular factors encouraged Russiato come up with an ambitious plan of the Extensive Eurasian Partnership, although theprospects of its implementation currently are uncertain. The present article argues thatthe success of Russia-China collaboration in Eurasia will depend crucially on the futuredynamics of the Eurasian integration, as well as on the agreement to co-develop theEurasian Economic Union and the Belt Initiative with concrete and mutually beneficialprojects.
