Abstract

The aim of this study was to elaborate a conceptual approach to the development of financial technologies under the impact of restrictions imposed by international economic sanctions. The development of this sector was analyzed based on empirical studies of available information on the state of the FinTech sector in 28 countries that are impacted by international economic sanctions, using the Global Sanctions Database presented by OFAC (Office of Foreign Assets Control). The research involved comprehensive research methods: situational analysis, system analysis, reproductive analysis, structural and functional analysis. The results of the study confirmed the main hypothesis: international economic sanctions do not block the development of financial technologies, as FinTech can ensure the development of the financial sphere of sanctioned countries because of its flexibility and mobility. The calculations proved that depending on the way of combining the internal perception of external restrictions imposed by the sanctions, which is unique for each country, international economic sanctions are a stimulator for some countries (China, Ukraine, Iran), while being a significant development blocker (r=0.896) for others (with a financial technology performance less than 1). This study will be useful not only to scholars who deal with the theoretical and methodological framework of the development of the financial sector of countries subject to sanctions.

Abstract

The COVID-19 pandemic impacted every aspect of life on a global scale. E-business has become a key factor influencing the profitability of businesses in various fields, regardless of their size. The aim of this study was to assess the effectiveness of e-business in entrepreneurship development in various fields during the COVID-19 pandemic. For this purpose, a panel analysis of data from 212 micro, small, medium-sized and large companies, and nine business sectors (trade, chemical, light, pharmaceutical, food, agricultural, HoReCo (hotel and restaurant industry), electronics and IT, transport) was used with data comparison for 2019 and 2020 in Ukraine, Bulgaria, Poland, Moldova and Georgia. The e-business platform was found to be the key indicator of maintaining performance during a pandemic. The analyzed questionnaire data show that 58% of respondents saw an increase in online income in 2020 compared to 2019 that in such sectors as trade, IT and pharmacy. There were 59% of respondents who saw the need to expand communication networks with existing and potential customers, because it was positively correlated with the efficiency of e-business. Besides, the results show that equity financing and proper liquidity management consolidate the economic performance of businesses in terms of return on equity and return on assets. Our findings are useful to managers and investors, and can help them make the best decisions about their management or investment activities. Moreover, the study demonstrates how companies were responding to the pandemic in order to identify sectors that are more vulnerable to the effects of the crisis and the key financial management decisions that companies need to make during the crisis.

Abstract

Background: Nucleosomes are the key structural elements of chromatin in all higher organisms. While X-ray crystallography studies of nucleosomes have consistently yielded similar atomistic structures, many biophysical and biochemical techniques suggest that nucleosomes and nucleosome complexes exhibit substantial conformational polymorphism, which is functionally important. The interpretation of such experimental data with such sufficient details is often a tedious task, thus a set of molecular modeling tools is required. Methods: We performed full-atom molecular dynamics of nucleosomes and DNA fluorescent labels to sample the conformations used for single particle Förster Resonance Energy Transfer (spFRET) measurements. We developed an approach for donor and acceptor quantum yield estimation, during spFRET measurements in a single laser excitation setup. We also implemented a set of methods for the integrative modeling of nucleosome structures based on spFRET constraints. Results: Using these approaches, we have constructed atomistic models of nucleosomes structural reorganization induced by histone chaperones or histone H1. Besides the distances derived from corrected spFRET efficiencies, histone - DNA contacts are crucial for nucleosome formation and function. We used hydroxyl DNA footprinting data, in conjunction with atomistic structures of nucleosomes enhanced by molecular dynamics simulations, to develop a computational method for the precise determination of DNA positioning in nucleosomes with single base pair resolution. Conclusion: We have developed a set of techniques for chromatin modeling on the nucleosomal level. Such approaches tightly integrate various experimental data (mainly corrected spFRET efficiencies and hydroxyl DNA footprints) into molecular modeling pipelines.

Abstract

Nucleosomes, containing histone variants H2A.Z, are important for gene transcription initiation and termination, chromosome segregation and DNA double-strand break repair, among other functions. However, the underlying mechanisms of how H2A.Z influences nucleosome stability, dynamics and DNA accessibility are not well understood, as experimental and computational evidence remains inconclusive. Our modeling efforts of human nucleosome stability and dynamics, along with comparisons with experimental data show that the incorporation of H2A.Z results in a substantial decrease of the energy barrier for DNA unwrapping. This leads to the spontaneous DNA unwrapping of about forty base pairs from both ends, nucleosome gapping and increased histone plasticity, which otherwise is not observed for canonical nucleosomes. We demonstrate that both N- and C-terminal tails of H2A.Z play major roles in these events, whereas the H3.3 variant exerts a negligible impact in modulating the DNA end unwrapping. In summary, our results indicate that H2A.Z deposition makes nucleosomes more mobile and DNA more accessible to transcriptional machinery and other chromatin components.

Abstract

Sağır, Özlem (Balikesir Author), Introduction More than 300 million surgical procedures are performed each year. Acute kidney injury (AKI) is a common complication after major surgery and is associated with adverse short-term and long-term outcomes. However, there is a large variation in the incidence of reported AKI rates. The establishment of an accurate epidemiology of surgery-associated AKI is important for healthcare policy, quality initiatives, clinical trials, as well as for improving guidelines. The objective of the Epidemiology of Surgery-associated Acute Kidney Injury (EPIS-AKI) trial is to prospectively evaluate the epidemiology of AKI after major surgery using the latest Kidney Disease: Improving Global Outcomes (KDIGO) consensus definition of AKI. Methods and analysis EPIS-AKI is an international prospective, observational, multicentre cohort study including 10 000 patients undergoing major surgery who are subsequently admitted to the ICU or a similar high dependency unit. The primary endpoint is the incidence of AKI within 72 hours after surgery according to the KDIGO criteria. Secondary endpoints include use of renal replacement therapy (RRT), mortality during ICU and hospital stay, length of ICU and hospital stay and major adverse kidney events (combined endpoint consisting of persistent renal dysfunction, RRT and mortality) at day 90. Further, we will evaluate preoperative and intraoperative risk factors affecting the incidence of postoperative AKI. In an add-on analysis, we will assess urinary biomarkers for early detection of AKI. Ethics and dissemination EPIS-AKI has been approved by the leading Ethics Committee of the Medical Council North Rhine-Westphalia, of the Westphalian Wilhelms-University Münster and the corresponding Ethics Committee at each participating site. Results will be disseminated widely and published in peer-reviewed journals, presented at conferences and used to design further AKI-related trials. Trial registration number NCT04165369. ©

Abstract

The purpose of the article is to identify the basic components that form the appropriate level of competitiveness of the enterprise on ProZorro electronic platforms. This is relevant because about 4000 purchases are announced on the ProZorro system every day. In this way, enterprises can increase the sales of their products. The expert method of research was used. The process of participation of enterprises in tenders placed on ProZorro e-commerce platforms is briefly characterized. This process includes submission of tender documents by the customer, submission of proposals by participants, bidding with the choice of the winner. During the research, the level of competitiveness of Aquapolimer Engineering LLC at the ProZorro electronic trading platforms was substantiated. This company specializes in complex solution of problems in designing, assembly and installation of treatment facilities, installation of tanks. Analysis of competitors of Aquapolimer Engineering LLC, which provide similar services, has been completed. For each competitor (30 in total), such indicators are presented as: number of concluded contracts, percentage of concluded contracts in total quantity, value of concluded contracts, average value of one contract, number of concluded contracts in one year, number of disqualifications and work experience. A rating scale for these criteria has been generated. The competitiveness schedule is presented. The strongest competitors for Aquapolimer Engineering LLC are found (only 13 out of 30). A similar assessment of the competitiveness of Aquapolimer Engineering LLC was also performed for 2017-2018. The strengths of the enterprise are revealed. This is the number of contracts and the value of contracts that increase every year. The participation of the company in tenders contributes to the increase of sales and increase of net profit. The share of products sold by Aquapolimer Engineering LLC increased to 76.3% in total volume due to participation in tenders. In general, the pros of the ProZorro system are identified. These are effective public procurement, reduction of corruption risks, implementation of an accessible tender monitoring process for all parties, creation of conditions for attracting new participants to the public procurement process. The practical value of the article is that this approach allows the company to evaluate its strengths and weaknesses among competitors applying for the same tender.

Abstract

The article examines modern methods of risk assessment, analyzes their advantages and disadvantages, as well as features of use. In particular, it is determined that most of them are based on the use of statistical data and postulates of probability theory. In the case when obtaining the necessary initial data is difficult, the methods of analogues or expert assessments are used, but they are subjective. In a separate group, we can distinguish methods that are based on the use of mathematical modeling, such as the scenarios method , project sensitivity analysis or game theory. Housing construction is characterized by a high level of risk, and the specifics of the industry complicate its unambiguous assessment and, consequently, its management. Therefore, to effectively manage the risks of financing the housing construction, it is necessary to choose an assessment method that can provide the most accurate result. The amount of risk in housing construction financing directly depends on the chosen financing mechanism, and its total value will consist of the sum of individual risks that arise at different stages of the process, and the amount of which can be estimated using different methods. It is necessary to develop a combined assessment model that not only combines different risks, but also considers them as a single object, the individual parts of which are not only related, but can also cross-influence each other. Such a model will combine economic-statistical, expert methods and methods of mathematical modeling.

Abstract

Recent literature is explored focusing on the relationship between symptoms of anorexia nervosa (AN) and other psychiatric disorders and lines of treatment. In AN, restrictive subtype, anxiety and obsessive-compulsive disorders are the most frequent co-morbidities. In AN, bulimic subtype, depression, emotional instability/borderline and dependency disorders are most frequent. Psychopharmacological treatment could be tried in cases with AN and co-morbid depression, but otherwise the evidence base is lacking and pharmacological treatment relies on case stories and experience.
