The effect of a new coronavirus infection caused by the SARS-CoV-2 virus on microcirculation in the conjunctiva

Introduction. The availability of an objective assessment of the microcirculatory bed is possible when examining the vessels of the conjunctiva. This is especially true in individuals who have had COVID-19 and have diseases associated with endothelial dysfunction.Aim. To study the microcirculation in the conjunctiva after a new coronavirus infection caused by the SARS-CoV-2 virus.Materials and methods. 83 patients with a history of coronavirus infection were examined. Patients were divided into 2 groups depending on the presence or absence of comorbidities. Group 1 patients (n = 42) with post-COVID changes in the conjunctiva (severe  injection of  the eyeball, chemosis, microhemorrhagia, folliculosis of  the tarsal and bulbar conjunctiva, the  presence of  a  nodular formation  (conflicts), slight edema of  the corneal epithelium) and a  history of  concomitant diseases: arterial hypertension, diabetes, coronary heart disease, atherosclerosis. Group 2 patients (n = 41) with no history of concomitant diseases and similar post-COVID changes in  the conjunctiva. The control group consisted of  healthy volunteers without a  history of coronavirus infection (n = 30). All subjects underwent laser Doppler flowmetry of the bulbar conjunctiva 3, 6, 12 months after the coronavirus infection.Results and discussion. In comparison with the control group of persons after 3 months, microcirculatory disorders were detected in both groups (group 1 – subcompensated, group 2 – decompensated). In group 1, after 6 months and 12 months, violations persisted in  the subcompensation stage, which were accompanied by an increase in  the intensity of  the functioning of  the regulatory systems of the microcirculation: the M index corresponded to normal values, and the values of σ and Kv were above the norm. After 6 months in group 2, compensation of microcirculatory disorders was noted (indicators M, σ, Kv were normal), which persisted even by 12 months of observation.Conclusion. The data obtained indicate that in patients with concomitant endothelial dysfunction, the processes of restoration of the microvasculature are slowed down

Intuition in business: Empirical base

In this article, the authors propose economic projection of the views of Daniel Kahneman on intuition. The authors believe intuition to act as an operative category in entrepreneurship. The results of given statistical experiment prove viability of the phenomenon of intuition when making investment decisions. Two independent mechanisms for investment decisions are being defined - the «rational» and the «intuitive» ones. The research leads to conclusion that entrepreneurs’ intuitive decisions possess a relatively high level of efficiency. © 2016 Fomin et al

Multi-critera selection of a corporate system by using paired comparison analysis

The paper presents the results of comparing foreign corporate information systems (CISs) obtained by using the classical analytic hierarchy process (AHP). The eight most common corporate information systems of international standards were analyzed, there were determined some classes of criteria which are vital when selecting a system, and for each criterion 3-4 most suitable systems were identifie

Formal methods of analysis and synthesis for decisions options during corporate information system development

The article presents a generalized approach to decision making in the process of application development based on cyclically repeating actions, including the synthesis of solution options and their analysis. They considered the basic methods of analysis and synthesis used in decision-making process on the design of corporate information systems (CIS). The description of the proposed generalized semantic model is given on the example of component interaction of the Integrated complex of high-level development tools and the functioning environment of corporate-level information systems (Platform). They analyzed the process of CIS IT infrastructure on the basis of the Platform and the specific steps of making a management decision for this exampl

The paper analyzes the current state of the labor market in Russia, shows the need to improve mathematical and software tools for managing the regional human resources potential and the imbalance between the labor markets (LM) and educational services market (ESM), and suggests an approach to building a model for identifying criteria that affect LM and ESM in the construction sector on the example of the Belgorod region. The features of the development of the construction sector in the Belgorod region are considered. Based on the analysis of the collected statistical data and expert judgments, groups of criteria and criteria in each group that affect the amount of imbalance are identifie

Effect of intake of Vitrum vitamin-mineral complex in combination with adaptogens on immune status and physical work capacity in highly skilled student athletes

Purpose of the study: to study the effect of Vitrum in combination with adaptogens on immunological reactivity and physical performance in athletes under conditions of intense training.Materials and methods: 4 groups of athletes, 10 people in each, went through a cycle of intensive training according to a specially developed methodology. Group I took Vitrum, group II — Vitrum + Eleutherococcus extract, group III — Vitrum + ginseng tincture. Group IV — ascorbic acid and was used as a control. Blood for analysis was taken from the cubital vein before and after 28 days of drug administration. Indicators of immunological reactivity were determined by modern laboratory methods. Physical performance was determined by the index of the Harvard step test (IHST) and the PWC170 test.Results: the use of Vitrum in combination with adaptogens promotes a significant increase in the parameters of humoral (increase in IgA by 32–40 %, IgM by 28–43 %, IgG by 9–14 %) and cellular (increasing the completeness of phagocytosis by 9–37 % immunity.Conclusion: intake of Vitrum in combination with adaptogens was accompanied by a significant increase in nonspecific immunity and increased the level of fitness

A new expedited approach to evaluate the importance of different crystal growth parameters on laser damage performance in KDP and DKDP

In this work, we investigate the laser-induced damage resistance at 355 nm in DKDP crystals grown with varying growth parameters, including temperature, speed of growth and impurity concentration. In order to perform this work, a DKDP crystal was grown over 34 days by the rapid-growth technique with varied growth conditions. By using the same crystal, we are able to isolate growth-related parameters affecting LID from raw material or other variations that are encountered when testing in different crystals. The objective is to find correlations of damage performance to growth conditions and reveal the key parameters for achieving DKDP material in which the number of damage initiating defects is reduced. This approach can lead to reliable and expedite information regarding the importance of different crystal growth parameters on the laser damage characteristics of these crystals
