Abstract
Dissolved organic matter (DOM) has an important impact on the water treatment and reuse of petroleum refinery wastewater. In order to improve the treatment efficiency, it is necessary to understand the chemical composition of the DOM in the treatment processes. In this paper, the molecular composition of DOM in wastewater samples from a representative refinery were characterized. The transformation of various compounds along the wastewater treatment processes was investigated. A total of 61 heteroatomic class species were detected from the DOM extracts, in which CHO (molecules composed of carbon, hydrogen, and oxygen atoms) and CHOS (CHO molecules that also contained sulfur) class species were the most abundant and account for 78.43% in relative mass peak abundance. The solid phase extraction DOM from the dichloromethane unextractable fraction exhibited a more complex molecular composition and contained more oxygen atoms than in the dichloromethane extract. During wastewater treatment processes, the chemical oxygen demand (COD) and ammonia-nitrogen were reduced by more than 90%. Volatile organic compounds (VOCs) accounted for about 30% of the total COD, in which benzene and toluene were dominant. After biochemical treatment, the VOCs were effectively removed but the molecular diversity of the DOM was increased and new compounds were generated. Sulfur-containing class species were more recalcitrant to biodegradation, so the origin and transformation of these compounds should be the subject of further research.
Apoptosis-Inducing Activity and Antiproliferative Effect of Gossypin on PC-3 Prostate Cancer Cells
Authors: Cinar Irfan 
Published: July 2020

Aim:
The rapid growth, morbidity and mortality of prostate cancer, and the lack of effective treatment
have attracted great interest of researchers to find novel cancer therapies aiming at the effect of gossypin on cell
proliferation and apoptosis of PC-3 cells.

Methods:
The effect of gossypin on cell viability was determined using MTT assay at 5-100μg/ml and cisplatin
(50μM) in a time-dependent manner in PC-3 cell lines. The expression levels of caspase-3 (CASP3) and
caspase-9 (CASP9) for apoptosis and Nuclear Factor Kappa B (NFKB1) for survival, inflammation, and growth
were evaluated by real-time PCR. Hoechst staining was used to analyze apoptosis.

Results:
Gossypin showed an anti-proliferative effect on PC3 cell line in a time- and dose-dependent manner. In
addition, gossypin led to a significant increase in apoptosis genes (CASP3, CASP9) when compared to control
while it caused a decrease in the level of NFKB1, which is accepted as apoptosis inhibitor (p<0.05) (cisplatin-like).
Gossypin 50 and 100μM significantly induced apoptotic mechanism in PC-3 cells. However, no apoptotic or
commonly stained nuclei have been observed in control group cells.

Conclusion:
The results indicated that gossypin can be defined as a promising anticancer agent for PC-3 human
prostate cancer cell line.

Published: July 2020

BackgroundProper training and follow-up for patients new to continuous glucose monitor (CGM) use are required to maintain adherence and achieve diabetes-related outcomes. However, CGM training is hampered by the lack of evidence-based standards and poor reimbursement. We hypothesized that web-based CGM training and education would be effective and could be provided with minimal burden to the health care team.ObjectiveThe aim of this study was to perform a pilot feasibility study testing a theory-driven, web-based intervention designed to provide extended training and follow-up support to adolescents and young adults newly implementing CGM and to describe CGM adherence, glycemic control, and CGM-specific psychosocial measures before and after the intervention.MethodsThe “Intervention Designed to Educate and improve Adherence through Learning to use CGM (IDEAL CGM)” web-based training intervention was based on supporting literature and theoretical concepts adapted from the health belief model and social cognitive theory. Patients new to CGM, who were aged 15-24 years with type 1 diabetes for more than 6 months were recruited from within a public university’s endocrinology clinic. Participants were randomized to enhanced standard care or enhanced standard care plus the IDEAL CGM intervention using a 1:3 randomization scheme. Hemoglobin A1c levels and psychosocial measures were assessed at baseline and 3 months after start of the intervention.ResultsTen eligible subjects were approached for recruitment and 8 were randomized. Within the IDEAL CGM group, 4 of the 6 participants received exposure to the web-based training. Half of the participants completed at least 5 of the 7 modules; however, dosage of the intervention and level of engagement varied widely among the participants. This study provided proof of concept for use of a web-based intervention to deliver follow-up CGM training and support. However, revisions to the intervention are needed in order to improve engagement and determine feasibility.ConclusionsThis pilot study underscores the importance of continued research efforts to optimize the use of web-based intervention tools for their potential to improve adherence and glycemic control and the psychosocial impact of the use of diabetes technologies without adding significant burden to the health care team. Enhancements should be made to the intervention to increase engagement, maximize responsiveness, and ensure attainment of the skills necessary to achieve consistent use and improvements in glycemic control prior to the design of a larger well-powered clinical trial to establish feasibility.Trial RegistrationClinicalTrials.gov NCT03367351, https://clinicaltrials.gov/ct2/show/NCT03367351.

Percutaneous nephrolithotomy (PCNL) is a well-established treatment for staghorn stones. Given the im-provement in technology and techniques of flexible ureterorenoscopic lasertripsy (FURS), we retrospectively compared its treatment outcome against PCNL for staghorn stones at our institution. Materials and Methods All patients with partial and complete staghorn stones treated by FURS or PCNL between December 2014 and December 2017 were included. Outcome measures included the duration of the procedure, length of stay, retreatment rate, auxiliary rate, complications, and clinical success rates (stone or dust-free status). Results Out of 22 staghorns, 10 (1 complete, 9 partial) had FURS and 12 (2 complete and 10 partial) had PCNL. Comparatively, the FURS group were older (mean 70.1 vs. 57.1 years, U-test p<0.001) with higher mean ASA scores (mean 2.3 vs. 1.5, U-test, p=0.04), with a similar body-mass index (mean 29.1 vs. 27.3), maximum stone size (29.7 vs. 34.6mm) and Hounsfield unit (836 vs. 891HU). FURS was quicker to clinical success (102.4min vs. 159.5min, U-test p<0.001) and had shorter hospital stay (1.1d vs. 3.5d, U-test p<0.001). Higher primary procedure success [80% vs. 36%, 95% CI = (-3.0%, 74.5%)], higher overall success [90% vs. 73%, 95% CI = (-22%, 51%)], similar retreatment rate (10%), and higher auxiliary treatment rate (100% vs. 18%) were observed. 1 patient from FURS had a small intrapa-renchymal aspect of staghorn inaccessible to a laser. There were no complications in the FURS group. In the PCNL group, one developed a pseudoaneurysm requiring embolization, and 1 had failed PCNL access (excluded from the statistical calculation). Conclusion Our preliminary data suggest that FURS is efficacious and safe for staghorn stones treatment, and comparable to PCNL. In this context, we highlight FURS potential role as first-line management of staghorn stones.

The Contemporary Political Processes Transformation in the Context of Society Digitalization: Key Scenarios
Authors: Volodenkov S. V. 
Published: July 2020

Intensive introduction into actual political practice of digital communication technologies causes the need for scientists and experts to study several important issues related to the phenomenon of digitalization at the current stage of human civilization evolution. First of all, we are interested in the question of whether the introduction of digital communications into contemporary political processes causes corresponding transformations in the spheres of the functioning of the state and society. How correct is it to talk about the digitalization of the state and society by political scientists? Another essential issue for us is the definition of influence vectors: do the emergence and widespread dissemination of new types of communication technologies affect the emergence and development of new types of social and political systems, or the state only uses new technological capabilities to ensure the effectiveness of political governance processes in today’s environment, maintaining and supporting the potential of traditional political regimes? What is the mutual influence of new communication technologies and political power institutions at present? Finally, the extremely important for us issue is what effects in the political sphere are generated by the implementation of digital communication technologies into actual practice and what are the main scenarios for the transformation of the contemporary political space in such conditions. Consideration of these issues is the subject of this work. The author makes an attempt to show that we can talk today about real transformations in the parameters of the state and society functioning, as well as in the sphere of their interaction. At the same time, traditional political regimes, having ceased to act as a monopoly source of political information due to the emergence of alternative actors of information and communication activities and the formation of competitive political space, are actively trying to maintain political control and stability in the current environment. Most scenarios of the evolution and transformation of the political space in the context of digitalization are associated precisely with the attempts of traditional institutions of power to maintain control over the sources, channels, and content of digital communication processes. At the same time, the socio-political interaction of the state and society becomes more intense in quantitative terms. However, the content side of this interaction is not undergoing significant changes.
Self-organization of Citizens in the Age of Digital Communications
Authors: Bronnikov I. A. 
Published: July 2020

The article addresses the issue of civic participation in online communities. It is shown that modern network technologies make it easy to combine institutionalized forms of civic participation with informal practices through social media. In today’s digital world, unique activities have appeared that were not feasible before the introduction of online technologies: hacktivism as a new type of civil disobedience, Internet propaganda, the viral launch of hashtags and challenges in TikTok, monitoring of electoral procedures for webcams, etc. According to the author of the article Numerous publications by scientists about the deep crisis of civil society institutions, in fact, do not describe the decline in civic participation, but its complication and reorientation to more non-hierarchical and creative practices with t ud amenable to analysis by customary methods. According to the author, the increasing influence of information and communication technologies on the political process has contributed to a refocusing of civic activism towards the mediation of politics and media activism. The article emphasizes that the capabilities of Internet technologies contribute to the alienation of citizens from real problems, the rooting of virtual imitation of civic participation, forming the so-called foci of fake activism.The article presents an analysis of a new form of citizen activity – online rallies. The April case of online rallies in 2020 is analyzed in detail using the “Talkers” service of the popular car navigator from Yandex. It is concluded that online rallies will gradually be introduced into the Russian political process. In this regard, online space is becoming more polarized and politically dangerous. It is proved that the self-organization of citizens in online communities contributes to the slow transformation of the existing institutional framework.
Formation of Digital Society and Geopolitical Competition
Authors: Efremenko D. V. 
Published: July 2020

The article discusses the growing interdependence between the geopolitical competition of great powers and the development of digital technologies. Throughout the 2010s, the contradictions of the leading states regarding the control and regulation of the Internet have noticeably intensified. In the absence of universal rules for information security, the Internet is evolving towards a kind of “gray zone” in which various actors can use the wide range of available tools to achieve their political or other goals without fear of being drawn into a full-scale conflict.Nowadays, the geopolitical rivalry, primarily between the United States and China, covers a wide range of digital technologies, including artificial intelligence. It is highly likely that during the 2020s, China and the United States will create two competing and increasingly less compatible global ecosystems for the development of the Internet of things, big data processing technologies, 5 G mobile communications, additive technologies, robotics, etc. The choice of one of the ecosystems will at the same time become a geopolitical choice, which, obviously, during the next decade all state actors in the system of international relations will have to make.

Published: July 2020

The standard genetic code consist of four nucleotide bases which encode genes to produce amino acids needed by living things. The addition of new base (Dummy) causes a sequence of bases to become five nucleotide bases called ancient genetic codes. The five base set is denoted by , where B forms group through matching , , , , and from set . Ancient genetic codes can be reviewed as algebraic structures as a vector spaces and other structures as symmetry groups. In this article, discussed the properties of symmetry groups from ancient genetic codes that will produce dihedral groups. The study began by constructing an expanded nucleotide base isomorphism with . The presence of base causes to have a cardinality of 24, denoted as with . isomorphic with which is denoted by . Group had three clasess of partitions based on strong-weak, purin-pyrimidin types, and amino-keto nucleotide groups which are denoted as , , and . All three classes are subgroups of . By using the rules of rotation and reflection in the four-side plane, it was found that only one group fulfilled the rule was named the dihedral group.
