Published: March 2022

Background: Endothelial dysfunction is the main link in the development of cardiovascular diseases, which leads to ischemic heart disease (coronary artery disease) and its complications. There are many medicines available for the treatment of coronary artery disease. However, not all groups of drugs are able to positively affect endothelial function. Purpose. Based on the literature data, to study the effect of the main groups of drugs for the treatment of coronary artery disease on endothelial function and systemic hemodynamics in cardiac surgery patients after myocardial revascularization. Material and methods: The review and analysis of literature data from 46 sources are presented. Results: Angiotensin converting enzyme receptor inhibitors, calcium sensitizers, phosphodiesterase type III inhibitors as well as beta blockers have a positive effect on endothelial function. Nitrates have a negative effect on its function in conditions of critical circulation and should be used with caution in endothelial dysfunction. Conclusion: The data obtained indicate a positive effect of angiotensin converting enzyme receptor inhibitors, calcium sensitizers, type III phosphodiesterase inhibitors and beta blockers on endothelial function. However, these groups of drugs can negatively affect systemic hemodynamics in the perioperative period, which requires a deliberate approach when prescribing them.

Background. Diabetes mellitus is a global threat to public health. DFU is a marker of increased mortality in diabetic patients. It is important to understand the factors that would indicate the appearance of complications of diabetes mellitus. Objective. To investigate the factors influencing the occurrence of complications in patients with diabetes mellitus, to identify independent predictors of complications. Material and methods. A prospective non-randomized observational study was carried out from June 1, 2021 to September 1, 2021. The study involved 42 patients. The patients were divided into 2 groups: group 1 included subjects with a history of type 2 diabetes, group 2 – those with type 2 diabetes, complicated by DFU. Results. During the study, the level of platelets in the blood of all patients was 222.0 (177.5; 318.5)×109/l. The platelet count in group 1 was equal to 186 (154.5; 251.5)×109/l, and in group 2 it was 326.0 (239.25; 357.25)×109/l, statistical differences were significant (p <0.001). We divided the patients with DFS according to the Wagner classification, where platelet counts were determined for each of the classification grades. The level of platelets in patients with grade 1 was 267.0 (222.0; 322.5)×109/l, in those with grade 2 – 358.0 (234.75; 280.25)×109/l, in subjects with grade 3 – 340 (309.5; 360.5)×109/l, in those with grade 4 – 328 (305,75; 330,0)×109/l, and in those with grade 5 – 404 (293.5; 407.75)×109/l. The obtained data showed that the platelet count in the blood of patients with diabetes mellitus, complicated by diabetic foot syndrome was higher, than in patients with diabetes mellitus without complications. The platelet count in patients with diabetic foot syndrome gradually increased with an increase in the degree on the Wagner scale. The blood platelet count can be useful in assessing the severity of diabetic foot syndrome. Conclusions. The platelet count in patients with type 2 diabetes can be considered as a laboratory criterion and an independent risk factor for complications.

Published: March 2022

Background: The most common reason for drug-induced long QT syndrome is the intake of class III antiarrhythmic agents (according to the Vaughan-Williams classification). Their therapeutic effect is based on the ventricular repolarization deceleration and QT interval prolongation. Combined therapy with antiarrhythmic agents and other drugs increases the risk of QT interval prolongation. Objective: To assess the quantitative and qualitative structure of pharmacological therapy in patients who receive antiarrhythmic therapy during their inpatient treatment in a cardiology hospital. Material and methods: A retrospective analysis of the medical records of 120 patients, predominantly of those with ischemic heart disease, arterial hypertension and cardiac arrhythmias was carried out. All patients were divided into 2 groups based on the degree of QT interval prolongation in response to antiarrhythmic therapy. All drug therapies were recorded (name, dose, frequency and duration of drug intake, indicated in the prescription sheet). Only the drugs included in the international Crediblemeds Database were considered to have influence on the duration of the QT interval. Results: The patients of both groups had no statistically significant differences in terms of the total number of drugs taken (7.3±2.4 in the first group versus 6.92±1.6 in the second group, p=0.12). The percentage ratio of drugs that affect the duration of the QT interval to the total amount of the drugs used was 26±15% in the first group and 20.5±8% in the second group, p=0.71. When assessing the duration of the corrected QT interval depending on the structure of the combinations of drugs used, the highest incidence of torsades de pointes and the highest corrected QT interval values (503.45±23.9 ms) were recorded in the subgroup of patients taking 3 such drugs at the same time. Conclusions: A positive correlation was established between the number of drugs that prolong the QT interval and the value of the corrected QT interval. No statistically significant differences were found in the quantitative and qualitative structure of pharmacological therapy in patients with and without prolongation of the QT interval.

The aim of the study was to conduct a comparative and retrospective analysis of the spectrum and sensitivity to antimicrobial drugs of clinically significant microorganisms in two departments of anesthesiology and intensive care of the Grodno University Clinic. Material and methods. A retrospective analysis of the data for 5 years of microbiological material obtained from patients with diseases caused by pathogenic and opportunistic bacteria from two departments of anesthesiology and resuscitation was carried out. Results. According to the results of five-year dynamics, the seeding rate of some microorganisms (K. pneumoniae, A.baumannii, coagulase-negative staphylococci) increased in intensive care units by 2-2.5 times. At the same time, there is a decrease in the sensitivity of these microorganisms (up to 15-30%) to antimicrobial drugs, including the reserve group. Conclusions. Constant microbiological monitoring makes it possible to objectively determine the resistance of microorganisms to antimicrobial drugs, implement the optimal tactics for the use of antimicrobial drugs and prevent an increase in the number of resistant strains.

An Unexpected Tandem Reaction between N-Butadienyl-N-alkylketene N,O-Trimethylsilylacetals of Propionamide and Activated Dienophiles like N-Phenyl-maleimide or Acryloyl Chloride
Authors: Baak Marcel , Rubin Yves , Franz Andreas , Stoeckli-Evans Helen , Bigler Laurant , Nachbauer Jürgen , Neier Reinhard
Published: March 2022

Starting from the N-butadienyl-N-alkylpropionamides 1a-1c the corresponding N,O-trimethylsilylacetals could be obtained using the mixture of LDA and trimethylsilyl chloride in THF. The unexpected reaction sequence Diels-Alder reaction/acylation between the N-butadienyl-N-alkylketene N,O-trimethylsilylacetal of propionamide (2a-2b) and N-phenylmaleimide produced tricyclic products rac-5a-rac-5b and bicyclic products rac-6a–rac-6b with high diastereoselectivity. The reaction of the N,O-trimethylsilylacetals 2a and 2c with acryloyl chloride in a similar sequence gave the bicyclic products rac-8a and rac-8c. The stepwise synthesis of bicyclic systems of this general structure could only be successfully executed in 26% yield treating the Diels-Alder product rac-10 with LDA.

Authors: Schürmann Peter , Gardet-Salvi Laura
Published: March 2022

Ferredoxin-thioredoxinreductase is an essential member of a light-dependent regulatory system in oxygenic photosynthesis. This enzyme is composed of two nonidentical subunits, contains a 4Fe-4S cluster of a yet unknown function, and a catalytically active dithiol group. We have used
N-ethylmaleimide to modify specifically the active site thiols of the protein and show that their chemical modification completely abolishes the catalytic capacity of the enzyme and causes changes in the absorption spectrum of the protein.

Unexpected Fluorescent Behavior of Maleimide Based Zwitterionic Molecule: Aggregation Induced Emission
Authors: Mukherjee Dr. Ishita
Published: March 2022

A novel traditional fluorophore free bright blue light emitting small organic molecule with aqueous solubility consisting N-substituted maleimide with zwitterionic side chain was explored. The combined experimental and theoretical studies revealed that the fluorescence originated due to the aggregation of N-substituted maleimide molecules named N-(ethyl sulfobetaine) maleimide (M) in solution. It was also observed that the aggregation induced emission (AIE) was originated after certain threshold concentration which was confirmed by both the experiment and the first principal calculations. The aggregation of the M molecule in solution happens predominantly due to nonbonded electrostatic interaction. This finding may add a new dimension to broad sensing application with a feasible molecular strategy.
Electron correlation and vibrational effects in predictions of paramagnetic NMR shifts
Authors: Jaworski Aleksander , Hedin Niklas
Published: March 2022

Electronic structure calculations are fundamentally important for the interpretation of nuclear magnetic resonance (NMR) spectra from paramagnetic systems that include organometallic and inorganic compounds, catalysts, or metal-binding sites in proteins. Prediction of induced paramagnetic NMR shifts requires knowledge of electron paramagnetic resonance (EPR) parameters: the electronic g tensor, zero-field splitting D tensor, and hyperfine A tensor. The isotropic part of A, called the hyperfine coupling constant (HFCC), is one of the most troublesome properties for quantum chemistry calculations. Yet, even relatively small errors in calculations of HFCC tend to propagate into large errors in the predicted NMR shifts. The poor quality of A tensors that are currently calculated by density functional theory (DFT) constitutes a bottleneck in improving the reliability of interpretation of the NMR spectra from paramagnetic systems. In this work, electron correlation effects in calculations of HFCCs with a hierarchy of ab initio methods were assessed, and the applicability of different levels of DFT approximations and the coupled cluster singles and doubles (CCSD) method was tested. These assessments were performed for the set of selected test systems comprising an organic radical, and complexes with transition metal and rare-earth ions, for which experimental data are available. Severe deficiencies of DFT were revealed but the CCSD method was able to deliver good agreement with experimental data for all systems considered, however, at substantial computational costs. We proposed a more computationally tractable alternative, where the A was computed with the coupled cluster theory exploiting locality of electron correlation. This alternative is based on the domain-based local pair natural orbital coupled cluster singles and doubles (DLPNO-CCSD) method. In this way the robustness and reliability of the coupled cluster theory were incorporated into the modern formalism for the prediction of induced paramagnetic NMR shifts, and became applicable to systems of chemical interest. This approach was verified for the bis(cyclopentadienyl)vanadium(II) complex (vanadocene), and the metal-binding site of the Zn(II) → Co(II) substituted superoxide dismutase (SOD) metalloprotein. Excellent agreement with experimental NMR shifts was achieved, which represented a substantial improvement over previous theoretical attempts. Effects of vibrational corrections to orbital shielding and hyperfine tensor were evaluated and discussed within the second-order vibrational perturbation theory (VPT2) framework.

Published: March 2022

Catalytic systems are complex and dynamic, exploring vast chemical spaces on multiple timescales. In this perspective, we discuss the dynamic behavior of heterogeneous thermal and electrocatalysts and the ensembles of many isomers which govern their behavior. We develop a new paradigm in catalysis theory in which highly fluxional systems, such as supported sub-nano clusters, isomerize on a much shorter timescale than that of the catalyzed reaction, so macroscopic properties arise from the thermal ensemble of isomers, not just the ground state. Accurate chemical predictions can only be reached through a many-structure picture of the catalyst, and we explain the breakdown of conventional methods such as linear scaling relations and size-selected prevention of sintering. We capitalize on the forward-looking discussion of the means of controlling the size of these dynamic ensembles. This control, such that the most effective or selective isomers can dominate the system, is essential for the fluxional catalyst to be practicable, and their targeted synthesis to be possible. It will also provide a fundamental lever of catalyst design. Finally, we discuss computational tools and experimental methods for probing ensembles and the role of specific isomers. We hope that catalyst optimization using chemically informed descriptors of ensemble nature and size will become a new norm in the field of catalysis and have broad impacts in sustainable energy, efficient chemical production, and more.

Published: March 2022

An experimental setup for molecular beam scattering from flat liquid sheets has been developed, with the goal of studying reactions at gas-liquid interfaces for volatile liquids. Specifically, a crossed molecular beam instrument that can measure angular and translational energy distributions of scattered products has been adapted for liquid jet scattering. A microfluidic chip is used to create a stable flat liquid sheet inside vacuum from which scattering occurs, and both evaporation and scattering from this sheet are characterized by a rotatable mass spectrometer that can measure product time-of-flight distributions. This manuscript describes the instrument and reports on first measurements of evaporation of dodecane and Ne from a Ne-doped dodecane flat jet, as well as scattering of Ne from a flat jet of pure dodecane.

Published: March 2022

Цель статьи состоит в выявлении роли платежеспособности организации, выступающей основным внешним критерием финансового состояния организации, поскольку именно через платежеспособность проявляется качество управления ее финансами. Поэтому платежеспособность рассматривается как обобщающая характеристика финансового состояния, зависящая от эффективности всех видов деятельности, а также от качества активов, привлечения финансовых ресурсов на выгодных условиях, рентабельности и т.д. Научная новизна исследования заключается в выявлении объективной оценки платежеспособности, которая возможна только при комплексном подходе, когда показатели, определяемые на основе баланса и отчета о финансовых результатах (на основе принципа начисления), увязываются с показателями отчета о движении денежных средств, составляемого на основе кассового принципа.

The solvency of an organization is the main external criterion of the financial condition of an organization, since it is through solvency that the quality of its financial management is manifested. Therefore, solvency is considered as a generalizing characteristic of the financial condition, depending on the efficiency of all types of activities, as well as on the quality of assets, attracting financial resources on favorable terms, profitability, etc. An objective assessment of solvency is possible only with an integrated approach, when the indicators determined on the basis of the balance sheet and the statement of financial results (on the basis of the accrual principle) are linked to the indicators of the cash flow statement compiled on the basis of the cash principle.

Привлечение инвестиций обеспечивает развитие предприятий и организаций как государственных, так и частных. Цель статьи - выявить особую сложность кредитования инвестиционных проектов в сфере АПК, обусловленную высокими рисками и недостаточно высоким уровнем рентабельности, что заставляет кредитные организации прибегать к ограниченному кредитованию. В статье представлены расчеты и выводы по принятому банком варианту кредитования инвестиционного проекта, предполагающему производство значительно сокращенной номенклатуры продукции переработки молока со значительно сокращенным инвестиционным покрытием потребности в финансовых ресурсах. Научная новизна заключается в доказательных мерах относительно экономических последствий ограничений в объеме кредитования со стороны банка. Такой подход к кредитному регулированию не всегда гарантирует мелким и средним предприятиям доступ к необходимому объему заемных средств для обеспечения эффективного роста и развития.

Attraction of investments ensures the development of enterprises and organizations, both public and private. At the same time, the particular difficulty of lending investment projects in the agro-industrial complex arises, first, due to high risks and insufficiently high level of profitability, which forces credit institutions to resort to limited lending. The article presents calculations and conclusions on the option of lending an investment project adopted by the bank, which implies the production of a significantly reduced range of milk processing products with significantly reduced investment coverage of the need for financial resources. Thus, on a clear example, you can see the economic consequences of restrictions on the volume of lending by the bank. This approach to credit regulation is a quantitative limitation of the amount of loans expected to be issued. In such conditions, it is not always possible for small and medium-sized enterprises to gain access to the required amount of borrowed funds to ensure effective growth and development.

Целью исследования является анализ качественных характеристик населения России в возрасте от 15 до 29 лет для составления портрета российской молодежи. Для этого были использованы данные из выборочного наблюдения доходов населения и участия в социальных программах (ВНДН). Исследование включает в себя рассмотрение портрета в динамике путем сравнения полученных значений в 2017 и в 2020 гг. На основе полученных данных автором построен портрет молодого безработного. Научная новизна заключается в выявлении проблемных точек в развитии молодежного рынка труда, поскольку наблюдающаяся тенденция прекаризации занятости молодежи требует разработки долгосрочной программы содействия занятости молодежи. Основные описательные характеристики российской молодежи, представленные в исследовании, впоследствии могут быть учтены при разработке такой программы.

The purpose of the study is to analyze the qualitative characteristics of the Russian population aged 15 to 29 years to draw up a portrait of Russian youth. To do this, data were used from a sample observation of population income and participation in social programs (GNPs). The study involves reviewing the portrait in dynamics by comparing the obtained values in 2017 and in 2020. Based on the data obtained by the author, a portrait of the young unemployed was built. The scientific novelty lies in the identification of problematic points in the development of the youth labour market, since the current trend of precaring youth employment requires the development of a long-term program to promote youth employment. The main descriptive characteristics of Russian youth presented in the study can subsequently be taken into account in the development of such a program.

As part of the study, it was found that the determining factor in the development of Russian-Vietnamese relations are geopolitical trends that are emerging both directly in the Asia-Pacific region and the nature of interaction or confrontation between key countries of the world, primarily Russia, China and the United States. The geopolitical confrontation between the above three countries is largely determined by the nature of Russian-Vietnamese relations. Strengthening and expansion of Russian-Vietnamese political and economic relations is under pressure of unprecedented pressure from both the countries of Europe, the USA, Australia, Japan due to the situation with the Crimea and the Eastern regions of Ukraine, and China, which, due to large-scale geopolitical ambitions, especially in the Asian region does not welcome the active rapprochement of Russia both with Vietnam and with any other country in the region. Based on the results of the study, the most promising areas of strengthening and further development of Russian-Vietnamese relations were identified and substantiated, which are mutually beneficial to both countries. Among the most promising areas, it is necessary to note cooperation in the energy sector, including the "peaceful atom", socio-cultural and biopharmaceutical spheres. The success and effectiveness of socio-economic cooperation between Russia and Vietnam will, oddly enough, depend not only on the countries themselves, but also on the nature of relations between Russia and Vietnam with such powers as China and the United States.

The article examines the Lebanese diaspora, its relations with the Lebanese society and the situation in the world. The data is analyzed and the location of Lebanese diasporas in different parts of the world is considered. Lebanese immigrant communities around the world make up the largest groups of Arab immigrants. As a diaspora, Lebanese communities have historical roots in almost every corner of the world. A more significant fact of the migration of Lebanese society is considered to be the beginning of the second half of the 19th century, the Lebanese immigrated to America, Africa and Northern Europe. Many factors have contributed to the spread of Lebanese society around the world. Lebanon has a free market economy and a strong commercial tradition of non-interference. The government does not restrict foreign investment, but the investment climate suffers from bureaucracy, corruption, arbitrary licensing decisions, complex customs procedures, high taxes, tariffs and fees, archaic legislation, and inadequate protection of intellectual property rights [4. Р. 143]. The idea of a diaspora-a dispersed ethnic group spanning national borders-has been revived by the intensity of global processes over the past few decades towards understanding the immigrant experience. In its Greek origin, the term diaspora means the scattering of seeds and thus means an association with migration and colonization, implying acculturation and assimilation while preserving an ingrained tradition. Also, the diaspora captures much of our analytical and popular imagination and requires explanatory power in describing the presence and conditions of the immigrant population. Understanding their position as a product of global economic, political and cultural dynamics, Lebanese immigrants demonstrate forms of identification, social ties and ways of cultural expression that take into account the global diaspora consciousness [2. Р. 82]. The diaspora, on the other hand, provides an entry into the study of the global situation and the dynamics of the economy. It should be noted that the Lebanese diaspora is an important group for studying the dynamics of immigration and how immigrants are affected by global economic, political and cultural processes.

The paper analyzes the economic and demographic indicators of the single-industry towns of the Perm Territory with the most difficult socio-economic situation (the so-called “red” zone single-industry towns) in the dynamics for 2012-2019. for subsequent comparison with respect to each other and the assumption of their further development. The analysis used data from municipal and regional statistics, materials from reports and reports of heads of settlements, as well as information from other studies on single-industry towns in the Perm Territory and Russia as a whole. On the basis of these data, an index of economic and demographic development was formed, being guided by which it is possible to trace the value of indicators and the rate of their change over the past decade. The highest index of economic and demographic development is characteristic of such settlements as the town. Uralsky, Ocher and Nytva, and the smallest value was shown by the township. Warm mountain. The results obtained made it possible to divide the monotowns into three groups and to suggest their further development according to the three proposed scenarios.

Pelapisan nikel mengkilap (Bright Nikel Electroplating) merupakan salah satu pelapisan yang banyak dipakai di Industri-industri kecil baik berupa sebagai lapisan dasar maupun untuk lapisan akhir. Kendala utama yang dihadapi adalah bahan-bahan larutan yang relatif mahal dan keberadaannya di pasar yang terbatas. Salah satu bahan yang mahal adalah NiCl2 dengan penggunaanya yang relatif lebih besaar dibanding bahan yang lainnya.

Tujuan penelitian ini adalah untuk mengetahui dapat atau tidaknya digunakan NaCl sebagai bahan pengganti dari NiCI2 dengan menggunakan kondisi pelapsisan yang konstan (temperatur, rapat arus, dan pH semua konstan). Dari hasil penelitian didapatkan bahan NaCI dapat menggantikan NiCI, dengan melihat tampak rupa, ketebalan, kekerasan dan daya lekat dari lapisan. Dari tampak rupa lapisan kedua-duanya menghasilkan lapisan mengkilap dengan ketebalan yang hampir sama (Â±56,3 : 50,1 Âµm), kekerasan yang tidak jauh berbeda (534,3 : 518,8 HK) serta daya lekaat lapisan yang masksimal (tidak mengelupas).
