Authors: Knysh O.V. , Nikitchenko Yu.V.
Published: April 2020

Probiotic microorganisms are known to be able to exhibit antioxidant activity. Most of beneficial probiotics effects are due to the action of their derivatives (structural components and metabolites). The aim of the work was to investigate the antiradical activity of cell-free extracts containing bacterial derivatives of Bifidobacterium bifidum 1 and Lactobacillus reuteri DSM 17938 probiotic strains, by their hydroxyl radical scavenging activity in the model system of their generation. Cell-free extracts were obtained from disintegrators and cultures of probiotic bacteria cultured in the disintegrators of their own cells. A metabiotic HYLAK FORTE was chosen as the reference drug. At a concentration 20% vol. in the incubation medium the hydroxyl radical scavenging by L. reuteri cell-free extracts was at a level of 75–90 %, and the hydroxyl radical scavenging by B. bifidum cell-free extracts was at a level of 50–60%. The metabiotic provided the same level of the hydroxyl radical scavenging activity when its content in the incubation medium was lower in 1.5 – 2.5 times. Extracts obtained from disintegrators showed a more pronounced antiradical activity than extracts from probiotic cultures. Based on the weight of the dry residue, concentrations for 50% hydroxyl radical scavenging (ІС50) by extracts and metabiotic were calculated. According to this indicator, L. reuteri extract obtained from disintegrate was the most effective (IC50 = 1.57 mg/ml). Other investigated derivative-containing products were arranged in decreasing order of antiradical activity as follows: B. bifidum extract from disintegrate (IC50 = 1, 64 mg/ml) > B. bifidum extract from culture (IC50 = 1, 75 mg/ml) > L. reuteri extract from culture (IC50 = 1, 86 mg/ml) > HYLAK FORTE (IC50 = 11, 03 mg/ml). Thus, all the studied extracts showed antiradical activity with respect to the most reactive hydroxyl radical. The obtained results encourage further study of the antioxidant properties of L. reuteri and B. bifidum cell-free extracts in order to elucidate the mechanisms of their biological activity and justify the appropriateness of their therapeutic use.

Published: April 2020

Reforming of higher medical education in Ukraine requires reconsidering of existing learning technologies and tools as well as creating the approaches meeting up-to-date demands in order to improve the professional training of highly qualified specialists who can compete in the global medical services market. Medical biology is one of the fundamental biomedical disciplines aimed at familiarizing students with concepts about the basic laws of functioning of living beings at all organizational levels. The knowledge students have gained when studying this discipline is of great practical importance, since theoretical material is associated with a range of clinical disciplines. Modern textbooks, manuals, dictionaries of scientific terms in medical biology contains many eponymous terms. These terms are also used in international publications. The eponymous terms are widely common in biology, anatomy, histology, cytology, embryology, physiology that enables to develop interdisciplinary integral relationships and contributes to the formation of a scientific worldview. The knowledge of these names and their appropriate usage even at the beginning of the special training of future doctors leads to an increase in the intellectual level, contributes to a deeper understanding of the scientific foundations of disciplines through the mastering professional terminology and the language of specialists. The clear perception of eponymous names from different branches of medicine is important for doctors of any speciality. This will facilitate their professional growth through communication with colleagues, help in working with special scientific literature, and stimulate the need for self-education and self-improvement. Eponymous terms are difficult to remember, difficult to transcribe and transliterate, but they help preserve traditions and history, glory the names of scientists and doctors who have made invaluable contributions to the development of medicine. The purpose of the publication is to analyze and highlight the role of eponymous terms that are used through the course of medical biology, in particular, the section of medical genetics, to focus on the structural features of these terminological units.

Published: April 2020

The article summarizes the main shortcomings in the functioning of university clinics, including inadequate  material and technical equipment, the lack of up-to-date diagnostic and treatment technologies, low salary for medical personnel and scientific staff, students’ insufficient practical training. All these issues necessitate the search for more effective forms of establishing university clinics, and, in particular, on the principles of public-private partnership (PPP).

It has been shown that one of the possible ways to develop university clinics is implementing private-public partnership (PPP) that can provide a number of advantages compared with purely public administration: private investment, development of innovative areas, ensuring economic stability, the influx of highly qualified personnel, providing high-quality medical care, ensuring profitability for enterprises etc.

The article provides the methodological approaches to elaborating the model of PPP establishing based on PPP principles. Within the methodological approaches, the key stages of the establishment and development of university clinics and their management have been identified. These stages enable to monitor the implementation of the strategies for developing university clinics and to make adjustments it in accordance with environmental conditions.

The methodological approaches presented in the article are summed up as a set of methods for investigating the possibilities and prospects of improving public and private business to solve a difficult practical task – to organize a modern university dental clinic based on PPP principles. The methodology of creating this model is an important prerequisite for organizing the model and serves as the basis for forming a modern management company, a legally independent high-technology clinical dental base of the university, and system of professional personnel training.
MORPHOLOGY AND FUNCTION OF THE AUTONOMOUS NERVOUS SYSTEM
Authors: Stepanchuk A.P.
Published: April 2020

The autonomic nervous system consists of the sympathetic and parasympathetic divisions. The central part is represented by supra-segmental and segmental centres. Parasympathetic segmental centres in the brain are accessory nucleus of the oculomotor nerves, superior salivary nucleus of the facial nerve, inferior salivary nucleus of the glossopharyngeal nerve and dorsal nucleus of the vagus nerve. In the spinal cord, these are the intermediate lateral nuclei. Sympathetic segmental centres in the brain are absent, and in the spinal cord, intermediate-lateral nuclei are located in the lateral horns in the eighth cervical, all thoracic and 1-2 lumbar spinal segments. The peripheral part of the autonomic nervous system is represented by pre-nodal and post-nodal branches, paravertebral, prevertebral and terminal nodes and plexuses. The intramural part of the autonomic nervous system lies in the larger part of a wide and narrow-loop net and represented with a large number of nerve cells different by their shapes and sizes and clustered as intramural nodes, or individual nerve cells included along the net loops. The autonomic plexuses of the abdominal cavity are topographically divided into celiac, superior and inferior mesenteric, abdominal aortic, mesenteric, superior and inferior hypogastric region.

Published: April 2020

Changes in the processes of lipid peroxidation and antioxidant system activity are involved in the pathogenesis of carcinogenesis and can affect tumor resistance to chemotherapy. The aim of this study to investigate the nature of changes in pro-oxidant-antioxidant status in patients with acute leukemia during remission induction chemotherapy.  Materials and methods. The study involved 42 patients with newly diagnosed acute leukemia, 22 of them were diagnosed to have acute myeloid leukemia and 20 patients had acute lymphoblastic leukemia. The age range was 18-58 years, there were 19 women (45.2%) and 23 men (54.8%). The patients were divided into two groups: I (n=22) included patients with acute myeloid leukemia, who had chemotherapy modes "7+3" and "5+2" for variants M0-2 and "7+3+etoposide" or "5+2+etoposide" for M4-5 variants; II (n=20) group included patients with acute lymphoblastic leukemia, who received chemotherapy according to D. Hoelzer protocol. Hemogram parameters (red blood cells, hemoglobin, white blood cells, platelets) were evaluated at baseline and on the 28th day of chemotherapy. The concentration of thiobarbituric acid reactive substances and catalase activity in the blood serum were assessed as well. Examination of acute myeloid leukemia patients was performed before the chemotherapy, on the 4th and 28th days since chemotherapy started; acute lymphoblastic leukemia patients were examined before chemotherapy, on the 23rd and 28th days. The group of healthy individuals consisted of 20 persons, including 9 (45%) women and 11 (55%) men, aged 22-26 years. Results. The detailed clinical picture of acute leukemia was accompanied by typical changes in hemogram in the patients of both test groups, and namely, by the development of leukocytosis, anemia, thrombocytopenia. At the same time, the patients with acute myeloid leukemia and acute lymphoblastic leukemia demonstrated an increased concentration of thiobarbituric acid reactive substances in 1.8 and 1.89 times, respectively (p<0.05) that was accompanied by an increased serum catalase activity in 1.96 and 1.8 times, respectively (p<0.05) compared to healthy individuals. During "7+3" chemotherapy, acute myeloid leukemia patients were found to show thiobarbituric acid reactive substances increased in 1.9 times on the 4th day of treatment and decreased on the 28th day.The patients with acute lymphoblastic leukemia managed according to the D. Hoelzer protocol demonstrated an increased concentration of thiobarbituric acid reactive substances in the blood serum in 1.33 times on the 23rd day of treatment (p<0.05), maintaining this level up to the 28th day. The catalase activity in the patients of the comparison groups did not change. Conclusion. The debut of acute leukemia is accompanied by activation of lipid peroxidation and antioxidant system enzymes. Сhemotherapy promotes the shift of the prooxidant-antioxidant equilibrium towards the lipid peroxidation activation.

Today, there have been numerous studies that show the emergence and development of various pathologies accompanied by the activation of free radical reactions. It should be noted that the current clinical experience and results of experimental studies indicate the important role of oxidative stress in the formation and progression of cardiovascular pathology, and a series of reports are devoted to the study and comparison of the distinctive features of free radical lipid oxidation and proteins in patients with endothelial dysfunction and various functional classes of angina. Despite the considerable period that has elapsed since the Chernobyl disaster, the medical and biological problems of long-term effects of ionizing radiation are remaining relevant. However, it should be noted that according to some authors, the ideas of lipid peroxidation, mainly based on in vitro studies, do not meet the requirements for recognizing the existence of a metabolic process or metabolic pathway. In recent years, the Department of Internal Medicine # 3 with Phthisiology has conducted the number of multidirectional studies focused on various aspects of free radical pathology in experimental and clinical medicine on cardiology, nephrology, immunology, haematology, pulmonology, and gastroenterology. According to the results of the literature review and comprehensive analysis of the conducted research, we can point out that the study of the role of free radical processes in experimental and clinical medicine is still remaining quite relevant. The scientific search and practical value of these studies can lead to new insight in the context of an overall deterioration of the environment and exposure to negative environmental factors.

Authors: Suprun E.V. , Tereshchenko M.S.
Published: April 2020

At present, due to spreading of alcoholic cardiomyopathy among the able-bodied population of industrialized countries, there is an urgent need to search for new medicines possessing a strictly targeted effect, taking into account the complex mechanisms of the damaging effects produced by ethyl alcohol on the myocardium. Therefore, the combination of L-arginine and thiotriazolin (developed by “Farmatron” scientific production association) is of great clinical interest. The same is relevant for Mildronate, Mexidol and Thiotriazolin. The aim of this research was to study the endothelioprotective effect of the medicine combining L-arginine with thiotriazoline (4: 1) (Argitril) in comparison with the standard metabolites as Mildronate, Mexidol, and Thiotirazoline on the morphological and functional characteristics of endotheliocytes and ST2 level in modelled cardiomyopathy and alcohol cardiomyopathy. Alcoholic cardiomyopathy was caused by intragastric administration of 20% ethanol solution in a dose of 8 g/kg for 90 days. All animals were divided into 5 groups, 10 animals in each. All the studied substances were administered intraperitoneally for 30 days: the combined medicine (L-arginine 100 mg/ml + thiotriazolin 25 mg/ml (4:1)) - 200 mg/kg (in recalculation for L-arginine); Mildronate (Grindeks, Latvia) - 250 mg/kg; Mexidol (NPK Farmasoft, Russia) - 200 mg/kg, Thiotriazolin (Galichfarm, Ukraine) - 50 mg/kg. The control and intact groups received physiological saline. The following indicators were assessed: endothelial cell nucleus area (μm2); the density of the nuclei of endotheliocytes (as an indicator for the number of cell nuclei per 1 mm2 of myocardial tissue area) and the relative area of endotheliocytes (%), ST2 protein.

The study has shown that on the 30th day after 90 days of the development of alcohol addiction, the animals were found out to have alcoholic cardiomyopathy. A significant decrease, by 32.38%, in the area of the nuclei of endotheliocytes was observed in the animals of the test group, the density of nuclei of the endotheliocytes lowered by 7% and the relative area of the nuclei of the endotheliocytes reduced by 21.89%. An increase in the concentration of ST2 protein was observed in 3.34 times compared with the intact animals that evidences the presence of endothelial dysfunction.

It has been experimentally proved that the combination of L-arginine/thiotriazolin significantly exceeds the reference medicines as Mildronate, Mexidol and Thiotriazolin in terms of endothelioprotective and cardioprotective effects (effect on the area and density of nuclei of endotheliocytes; concentration of ST2 protein).

Published: April 2020

The article describes the study on the effectiveness of remedies possessing antioxidant properties for chemoprevention of the consequences caused by pesticides toxic effects. 2,4-dichlorophenoxyacetic acid derivatives, and namely, amine salt of 2,4-dichlorophenoxyacetic acid are known as one of the most widely distributed compounds in agriculture. The activation of the free radical processes is considered as a universal mechanism of the damage to biological membranes during chronic intoxication by phenoxyacid derivatives.  This work is aimed to compare the preventive effect of the synthetic and natural antioxidants under long-term exposure to the 2,4 - dichlorophenoxyacetic acid. The experiment was performed on Wistar male rats, which received synthetic and natural antioxidants against the background of toxicant administration. Long-term effects of the pesticide caused the activation of the processes of free radical lipid peroxidation, reduced antioxidant supply and activity of antioxidant enzymes. The introduction of medicines with antioxidant properties helped to reduce the content of products of free radical processes, to inhibit the drop of body antioxidant supply and to normalize the activity of antioxidant enzymes.

According to the experimental data obtained, the complex of natural antioxidants (tocopherol acetate, ascorbic acid and quercetin)   has   the most pronounced corrective properties. This enables us to recommend them for chemocorrection of pathological changes resulted from prolonged exposure to pesticides.

The paper presented summarizes the results on the parameters of free radical lipid oxidation and antioxidant protection factors in 24 children aged from 3 to 15 years with acute odontogenic mandible osteomyelitis. In addition to standard clinical examination, peripheral blood and unstimulated oral fluid fractions were collected from all patients for 10 min at hospital admission and discharge. The samples were used to determine the components of lipid peroxidation: diene conjugates; malondialdehyde, its initial level, in 1.5 hours of incubation and its growth; antioxidant protection factors as superoxide dismutase, and catalase. It has been found out at the time of hospitalization, clinical examination showed a significant deterioration of the general condition, which was accompanied by widespread infiltrative changes and collateral oedema in the projection of the involved region of the mandible. In 12 people (50%) osteomyelitis spread from temporary molars. In other cases, permanent first and second molars were regarded as the causes. The patients demonstrated the activation of lipid peroxidation processes and reduction of antioxidant protection factors found out in peripheral blood and unstimulated oral fluid fraction. Repeated studies over the clinical recovery following the treatment conducted in accordance with the protocol of medical care enables to estimate the absence of infiltrative changes, but despite the elimination of acute inflammation, not all the studied parameters reached the level of control values. This makes it necessary to address the issue on making corrections towards the complex of therapeutic measures by including antioxidants that seems to be quiet promising and requires further in-depth investigation.

Published: April 2020

The study was aimed as investigating the effects of inhibitors of transcription factors NF kappa B and AP-1 activation on the development of oxidative-nitrosative stress in rat cerebral hemispheres following experimental traumatic brain injury (TBI). The study included 60 white Wistar male rats weighing 180-220 g, divided into 4 groups of 7 animals in each: the 1st group included pseudo-injured animals subjected to the same manipulations (ether anaesthesia, fixation) as the animals  in the experimental groups, except for TBI modelling, the 2nd group included the animals exposed to modelled TBI, the 3rd and 4th groups involved the rats who received ammonium pyrolidine dithiocarbamate, the nuclear translocation inhibitor NF kappa B in a dose of 76 mg/kg and the inhibitor AP-1 SR 11302 in a dose of 1 mg/kg, respectively for 7 days following the TBI modelling. On the 7th day after the simulation of a moderate TBI in rat cerebral hemisphere tissue, the following signs of oxidative-nitrosative stress have been detected: increased production of superoxide radical anion by NADPH and NADH-dependent electron transport chains, increased activity of nitric oxide synthase (total and inducible), a decrease and impairment of the coupling of its constitutive isoform, growth in the concentration of peroxynitrite, the development of decompensated lipid peroxidation. The application of transcription factor inhibitors NF kappa B (PDTC) and AP-1 (SR 11302) significantly reduces the signs of oxidative-nitrosative stress in the tissue of rat cerebral hemispheres on the 7th day of the experiment, reduces the production of superoxide anion radical and the activity of nitric oxide synthase (total and inducible), improves the coupling of its constitutive isoform, limits the peroxynitrite concentration, and enhances the antioxidant potential.

Authors: Halchenko A. , Kydon P.
Published: April 2020

Rapid social transformations occurring worldwide, on the one hand, lead to the tension of adaptation mechanisms that is reflected through the prevalence of mental disorders, primarily of a psychogenic nature. On the other hand, clinical manifestations of psychogenic disorders are altering as their symptoms are always closely related to the nature of surrounding influences and to some extent reflect the patterns of social processes. From this point of view, clinical, psychopathological and pathopsychological features of adjustment disorders, and in particular in internally displaced persons, are of clinical and social importance. The purpose of the study was to explore the clinical psychopathological and pathopsychological features of psychosocial maladaptation in internally displaced persons with adjustment disorders. 45 people were diagnosed with adjustment disorders and clinically defined psychosocial maladaptation. The control group consisted of 35 healthy individuals with no signs of psychosocial maladjustment. All the participants were internally displaced from Donetsk, Luhansk and Crimea. According to the results of the research, we have found out that the leading factors resulting in psychotraumas in internally displaced persons with adjustment disorders and psychosocial maladaptation include media coverage of information and family aspects. The clinical picture was characterized by the dominance of anxiety-depressive symptoms with various somatic manifestations. We have established patterns of clinical and psychopathological features typical for internally displaced people with signs of psychosocial maladaptation.

TRANSLATED LITERATURE IN COCHINCHINA IN THE LATE 19th CENTURY AND IN THE EARLY 20th CENTURY
Authors: Vo Nhon Van
Published: April 2020

Being colonized by France, Cocochina (the South of Vietnam) was the region where Western literature was introduced into earlier than the North. Truong Minh Ky was considered the first translator of Western literature in Vietnam. His earliest works of translation appeared in 1884. By the early 20th century, introduced to Vietnamese readers were Western literary works not only of French origin but also of British, American and Russian origins; not only poetry, prose but also drama. In the late 19th century, many writers such as Truong Vinh Ky, Huynh Tinh Cua were interested in Chinese literature. In the first decade of the 20th century, a wide variety of Chinese novels were translated into Vietnamese, forming a strong movement of translating "truyen Tau” (Chinese fictions). The remarkable characteristics of the translation of Western literature in Cochinchina were as follows - The newspapers and magazines in “Quoc Ngu” (Vietnamese language written in Latin characters) where the first works of translation were published played very important role. - The translators were greatly diverse, coming from different social and cultural backgrounds. - More translation was made on prose. Novels of martial arts, historical stories, novels of heroic deeds attracted the attention of the translators and the publishers. Therefore, they were translated much more than romance novels were, because of their compatibility with popular audience. - By translating the works of Western literature, the writers tried to express new concepts of humanism, such as women rights, or gender issues. Translated literature in Cocochina in the late 19th and early 20th centuries reflects a paradox: Western influences started to leave their marks but the Chinese influence was still strongly engraved. However, this was a remarkable step in the journey of modernization of national literature. Through these early translated works, new literary genres were introduced and Vietnamese readers gradually became familiar with them. Translation experiences were the first steps for Cocochina writers to achieve thorough understanding, to learn Western writing techniques and styles, which helped them become the pioneers of new literature in Vietnam.
THE ROLE OF “DUY TAN TAM KIET” IN MEIJI RESTORATION
Authors: Huynh Anh Phuong
Published: April 2020

The Meiji Restoration stands as a turning-point in Japanese history. This significant turning point became the immediate point of departure for modernization and industrialization lasting from the end of the 19th century to the early 20th century in Japan. Due to this restoration, Japan began taking the first step towards becoming an independent, modern and powerful state in the Asian region. One of the most important factors which contributes to the Meiji’s restoration is the role of dominant political leaders, the most notable being the role of “Duy tan tam kiet”. “Duy tan tam kiet” is a popular label as “triumvirate” to designate three great men: Saigo Takamori, Okubo Toshimichi and Kido Takayoshi. They are considered the first group of leaders who guided the nation during the first years following the Restoration. These great men not only played an important role in overthrowing Bakufu Tokugawa government but also held dominant power in the first half of Meiji era. After throwing the Tokugawa government, they helped the emperor to carry out many effective policies which were essential contributions to the construction of the new state as well as to a period of rapid change. These pages are designed to provide a general overview of the role of “Duy tan tam kiet” in Meiji Restoration, especially their effective and decisive policies in the overall modernization process.

Published: April 2020

Coffee husks is a typical by-product in the coffee bean industry. This by-product has a high biological activity, but recently in Vietnam, it has been used as fuel, fertilizer, and substrate for mushroom cultivation. This study aims to identify conditions for extracting polyphenol from ripe robusta coffee husks from Dăklak province. Factors affecting the extraction process are pH, temperature, coffee husks : solvent ratio, and time. The obtaining data showed that extracting at pH=4, 50oC, with the solvent:coffee husks ratio = 7:1, during 1 hour would contribute the best results in terms of an extraction efficiency of soluble solids (33 %), the extraction efficiency of polyphenol (94 %), antioxidant activity according to DPPH assay (1959 ± 168 µM TE/ g dry matter of extracted solution) and FRAP assay (1976 ± 117 µM TE/ g dry matter of extracted solution). In addition, the extracted solution from the coffee husk is a potential source of polyphenol, as well as the antioxidant capacity that could be applied to future researches..

Objective: Endoscopic duodenal biopsies constitute a significant load of specimens in the histopathological section of a tertiary care hospital. Most of these diseases comprise non-neoplastic lesions causing significant morbidity. The purpose of this study was to see the frequency of these diseases in our patient population and to compare and analyze our results with similar other studies.

Methods: In this retrospective study records of all duodenal biopsies reported from Feb 2017- Jan 2018 were retrieved. Both non neoplastic and neoplastic conditions along with biopsies with unremarkable findings were included. Various histological parameters like villous blunting, IEL count per 100 enterocytes, crypt hyperplasia, inflammation in lamina propria, and presence of microorganisms, any dysplasia or malignancy were studied. Data was statistically analyzed using SPSS v.23.

Results: A total of 159 duodenal biopsies were included in the study. Normal duodenal morphology was noted in 85 (53.45%) cases while 74 (46.83%) cases revealed abnormal duodenal pathology. There were 46 (28.93%) cases consistent with celiac disease. Twenty eight (17.61%) cases were of other duodenal pathologies of which non-specific duodenitis was most common. There were 22 (13.83%) cases of duodenitis and 2 (1.26%) cases were of duodenal ulcer. One case (0.62%) each was seen of Brunner gland hyperplasia, adenocarcinoma, signet ring carcinoma and one case was of metastatic adenocarcinoma.

Conclusion: In our study we found a significant percentage of 46.83% exhibiting abnormal duodenal pathology. Cases consistent with celiac disease were 28.93% while 13.83% of the cases had duodenitis. The percentage of malignant cases was minimal (1.88%).
The global polio eradication initiative in Pakistan: Lessons learnt and prospects for success
Authors: Naseem Sajida
Published: April 2020

Poliomyelitis commonly called polio is a highly infectious disease caused by three sero types of polio virus 1, 2 and 3, which attacks the nervous system. The virus is transmitted mostly through feco-oral route, less often it is transmitted through polluted food or water. Since there is no treatment or cure to poliomyelitis, this disease can be prevented only. The World Health Assembly in 1988 set the target to eradicate polio globally by the year 2000 through multiple doses of childhood vaccinations that protect a child for whole life.
Fiscal powers of municipalities in Russia’s resource-rich regions and fixed capital investment
Authors: Timushev Evgeny N.
Published: April 2020

The article considers the nature and limits of the impact local fiscal decentralization exerts on private fixed capital investments in resource-rich Russia’s regions. The relevance of this topic is due, firstly, to the fact that sufficient expenditure and revenue powers at the local level ensure sustainable economic development, and secondly, the lack of research on relationship between investments and local fiscal decentralization in Russia. The study confirms the existence of an inverted U-shaped curve in the investment-decentralization association for the group of resource-rich regions as well as the superiority of revenue decentralization over expenditure decentralization in terms of its impact on economic development. For 2009—2016, investments were the highest when local fiscal decentralization was 46—47% and 43—51% in expenditure and revenue aspects, respectively (for Russia as a whole, 35—36% and 33—34%). Tax revenues in those figures do not exceed 30 p.p., the rest is occupied by earmarked grants (subsidies) and, especially, general-purpose grants (“dotatsii”). The excess of the optimal level of revenue decentralization over the expenditure one in resource-rich regions is explained by drivers of relatively large local powers there — less dependence on federal transfers, low regional tax burden, and greater elasticity of regional fiscal policy to external factors. The overall excess of optimal levels in comparison to Russia as a whole is explained by high local demand for both differentiation of expenditures and intraregional intergovernmental redistribution in those regions. Reduction of fiscal decentralization for 2008—2018 curbed private investment. The greatest losses were incurred by lack of revenue decentralization in the resource-rich regions, which could have reached more than 80% of the median investments.
Central bank digital currencies: Potential risks and benefits
Authors: Sinelnikova-Muryleva Elena V.
Published: April 2020

A growing activity has recently been watched in the sphere of central bank digital currencies (CBDC) creation, dictated by the desire of monetary authorities to increase the efficiency of payment systems and create an alternative to stablecoin projects like Libra. The paper discusses various types of CBCDs. Special attention is paid to potential risks and benefits associated with the emission of CBDCs, as well as their consequences for the banking sector and monetary policy. The first important issue associated with CBDC emission is the potential reduction of the role of the traditional banking system. The second issue is the change in the functioning of the monetary transmission channels as a result of the CBDCs emission. The third problem arises from the fact that in the event of a crisis some economic agents will prefer to transfer their funds from commercial banks to the CBDCs because they are less risky. This situation is expected to lead to instability of balances on deposit accounts in commercial banks. The problems listed are closely interrelated, and the significance and balance of risks and benefits associated with CBDCs emission are not completely obvious. At the same time CBDCs have a potential to become a new effective tool of monetary authorities in case of their proper design.
Narrative analysis in economics as climbing complexity
Authors: Tambovtsev Vitaly L.
Published: April 2020

Two turns in economics during last decades are analyzed — complexity turn, and information turn, and the narrative analysis role for these turns realization is discussed. Basic framework of narrative analysis is described, and it is shown that its efficacy is limited by groups of individuals which have resources that give them possibilities to treat the narrative’s plot as a feasible alternative in decision-making situation. It is grounded that now agent-based models are the effective instrument for theoretical and empirical research under turns to complexity or information alike.
Deterioration Prediction Modelling and Inspection Schedule Estimation for Concrete Bridge Decks
Authors: Chyad Aqeed Mohsin , Abudayyeh Osama
Published: April 2020

Accurate and reliable deterioration rate estimates for concrete bridge decks are an important part of the overall bridge condition assessment. The main objective of this paper is to determine the time in condition ratings (TICRs) of concrete bridge decks and assess the impact of average daily traffic (ADT), age, and deck area on the bridge deck condition. Condition ratings of bridge decks over 24 years for Michigan state were collected from the National Bridge Inventory (NBI) data. The Anderson-Darling statistical test was used to evaluate and rank five practical probability distribution functions to select the best fit for Michigan state data. The results indicate that the best statistical model for Michigan state data is the lognormal function. It was illustrated that the TICR decreases when the condition rating decreases. When a concrete bridge deck condition is rated at 8, it can take 11.29 years to drop to the lower rating of 7. However, when the concrete bridge deck condition is rated at 4, it may take 6.64 years to drop to the lower condition rating of 3. It was also observed that on average, bridge decks in Michigan stay much longer than the typical inspection interval (i.e., 2 years), suggesting that inspection intervals can be longer than 2 years for bridges in good condition ranges. The results also show that ADT, age, and deck area are important factors in the deterioration rates of concrete bridge decks.
The Effect of Rapid Solidification on Microstructure and Corrosion of Advanced Biomaterial Co-Cr-Mo-C Alloy
Authors: Erfanian-NazifToosi Hamid-Reza , Lopez Hugo F.
Published: April 2020

In this research, the microstructure and corrosion properties of rapidly solidified Co-Cr-Mo-C alloy as an advanced biomaterial alloy were studied. The use of rapid solidification casting method represents significant changes in not only the amount of formed e-HCP phase, which is strongly influenced by rapid solidification, but also in electrochemical behavior and solidified structure. In this research, rapid solidified Co-Cr-Mo-C alloy is studied using OM, SEM, EDS, XRD, and dynamic potentiostate.  Co-alloy ingots were melted into an induction furnace filled by argon gas and casted into a V-shape sand and chill copper molds to prepare rapid solidified samples and its properties were measured in different cooling rates. The microstructure examination demonstrating the structure of alloy is mainly consist of columnar dendritic structure with the distribution of carbides within primary and secondary dendrites arms and finer dendritic structure along with modified carbide distribution will be achieved by rapid solidification. This structure will improve alloy’s corrosion behavior and reduces its corrosion rate when it is tested in Ringer’s solution as an electrolyte.

No final de dezembro de 2019, em Wuhan, China, surgiu uma nova variedade do Coronavírus, sendo declarado como uma emergência em saúde pública mundial pela Organização Mundial da Saúde (OMS). O tropismo pelas vias aéreas pode dever-se a expressão da enzima conversora de angiotensina 2 (ACE2). Na região da Amazônia Legal brasileira, até 22 de março de 2020, o Estado do Amazonas apresentou 26 casos confirmados; o Acre 11 casos; o Pará 04; Rondônia 03; Roraima, Tocantins, Maranhão e Mato Grosso 02 casos; e o Amapá apenas 01 caso confirmado. Este estudo visa quantificar e analisar os primeiras casos suspeitos e confirmados de COVID-19 em Macapá, Amapá, Amazônia, Brasil. Trata-se de um estudo observacional, retrospectivo e quantitativo, referente ao perfil dos 108 primeiros casos suspeitos notificados em Macapá, entre 13 de março de 2020 e 21 de março de 2020, e aos cálculos de incidência de COVID-19 nas 26 capitais brasileiras e Brasília, Distrito Federal, entre 26 de Fevereiro de 2020 e 26 de Março de 2020. Os estudos realizados podem revelar um padrão próprio de disseminação do vírus, o que contribuiria para o planejamento e para a implementação de medidas de controle e de vigilância epidemiológica mais efetivas.

The Topological Indices of the Non-commuting Graph for Symmetric Groups
Authors: Alimon Nur Idayu , Sarmin Nor Haniza , Erfanian Ahmad
Published: April 2020

Topological indices are the numerical values that can be calculated from a graph and it is calculated based on the molecular graph of a chemical compound. It is often used in chemistry to analyse the physical properties of the molecule which can be represented as a graph with a set of vertices and edges. Meanwhile, the non-commuting graph is the graph of vertex set whose vertices are non-central elements and two distinct vertices are joined by an edge if they do not commute. The symmetric group, denoted as S_n, is a set of all permutation under composition. In this paper, two of the topological indices, namely the Wiener index and the Zagreb index of the non-commuting graph for symmetric groups of order 6 and 24 are determined.
