Background: The aim of this study was to investigate the antioxidant and anti-inflammatory properties of pomiferin, a prenylated flavonoid was purified from Maclura pomifera by thin layer chromatography method, on oxidative stress, sterile inflamation and ovarian tissue damage caused by ischemia-reperfusion model.
Methods: Thirty female Wistar albino rats were divided into five groups. In the group CN only laparotomy operation was performed. In group CNPomiferin, rats received 200 mg/kg pomiferin. In group IRVehicle, reperfusion for 3 h performed after an ischemic period of 3 hours. In groups IRPomiferin100 and IRPomiferin200 rats received 100 mg/kg and 200 mg/kg doses of pomiferin, by oral gavage 1 houes before reperfusion. After the experiments, tissue level of malondialdehyde (MDA) and activities of myeloperoxidase (MPO), catalase (CAT), superoxide dismutase (SOD) were determined, and histopathological changes were examined in all rat ovarian tissue.
Results: It was determined that irreversible cell damage such as apoptotic and necrotic deaths and reversible cell damage occurred in follicular, endothelial and stromal cells due to oxidative stress in the group IRVehicle. In this group, it was determined that the LPO level exceeded the cellular antioxidant capacity (SOD and CAT enzyme activities) and the PMNL infiltration and activity (MPO), an indicator of sterile inflammation, increased. It was determined that oxidative stress sterile inflammation and irreversible cell damage decreased in a dose-dependent manner with pomiferin treatment.
Conclusions: Pomipherin treatment strongly protects ovarian follicles and vascular structures against ischemia-reperfusion injury, thus it may prevent the reduction of ovarian follicle reserve, which is an indicator of female fertility.

Published: January 2023

Tuberculosis (TB) and malignancy are global threats and have claimed millions of lives worldwide. TB is a preventable and curable disease prevalent in developing countries. It is well known to be a diagnostic chameleon and often mimic malignancy. Laryngeal TB is an extremely rare form of TB and has many similarities to laryngeal carcinoma. This case report highlights the importance of diagnostic biopsy in a 57-year-old gentleman with characteristic presenting features of laryngeal TB that is persistent hoarseness and haemoptysis. He was investigated and treated for pulmonary TB however his laryngoscopy biopsy revealed to be laryngeal carcinoma. Based on this case report, it is shown that malignancy could have easily been missed had a presumptive diagnosis of laryngeal TB been made initially. Nevertheless, when evaluating dysphonia in a patient, while it is important to consider laryngeal carcinoma, laryngeal TB must also not be overlooked as possibility, especially in endemic areas.
Establishing of UNCTAD in 1964 and the Logic of the Cold War: Economic Diplomacy of the GDR in the Struggle for International Recognition
Authors: Yablokov Boris
Published: January 2023

This article is dedicated to the problem of preparation and participation of the socialist countries in the first United Nations Conference on Trade and Development (UNCTAD), held in Geneva from March 23 to June 16, 1964. On the basis of the documents of the Russian State Economy Archive (RGAE) being introduced into science the author shows the importance the Soviet leadership attached to economic diplomacy, actively using for its realization the CMEA mechanisms. The practical embodiment of this was the solidarity position at the conference of socialist countries, prepared through the decisions of the II meeting of the Executive Committee of the CMEA in 1962 and aimed to establish a new international trade organization (ITO), one of the founding principles of which was to be universal membership. Unlike the FRG, which at that time was a member of the specialized organizations of the UN and thus had the right to participate fully in the 1964 conference, the GDR could only rely on collective forms of representation, above all as a member of the CMEA delegation. Thus, the solidarity-based struggle of socialist countries for international legal recognition of the GDR at the UN level, including through international economic organizations such as UNCTAD, strengthened the international status of CMEA, which sought to turn world trade into a tool for expanding its economic influence, including in the Third World.
Rochdale Pioneers: Myths and Facts
Authors: Novichenko Irina
Published: January 2023

The history of the Rochdale Pioneers, the founders of the consumer co-operatives in Great Britain, is repeated by all who turn to the history of the co-operative and labour movements. This “story” is always the same, researchers retell approximately the same facts. The article attempts to trace how the “typical story” about the Rochdale Pioneers developed in Russian and British historiography and how it is seen in the light of recent research. The documents of the “Rochdale Society of Equitable Pioneers” and the data from recent studies of British historians helped to consider the background of the event; the circumstances of the creation of the Society, the number of founding pioneers, their professional affiliation, age composition, adherence to Owenist and other socio-political ideas; relations with other cooperatives and authorities; the rules and objectives set out in the Statute of 1844 and subsequent statutes; the main directions of the Society's activity in 1844—1860s; the fate of the founding pioneers. Particular attention is paid to the evolution of the principles of the Rochdale co-operative system and to the efforts to preserve the heritage of the Pioneers.
On the Byzantine-Mongol Marriages
Authors: Korobeynikov Dmitry
Published: January 2023

The article focuses on the rapprochement between Byzantium and the Mongols from the 1250s which resulted in marriage alliances between Mongol Khans and Byzantine despoinas (princesses). The key issue is a clash of two different approaches. The Byzantine one was focused on the exclusive status of Byzantium as Christian Roman Empire, whose status was unrivalled and whose sovereigns seldom allowed marriages of Byzantine ladies to the foreign rulers, especially if the latter were heathen or Muslim. The Mongol view considered the Mongol state as the only one destined to dominate over other states. Here, the marriages between Mongol rulers and foreign brides have been suggested as one of vital elements of such domination. The compromise between two views seemed to have been made by the Byzantines: while the Byzantine church law refused to recognize interconfessional marriages, the Byzantines began to see these marriages as a Christian mission of sorts as the Greek brides and wives could have served as agents for spreading Greek Orthodox Christianity. Given the fact that some Khans had already converted to Islam prior to the marriage, these were also the first marriages between the Byzantine Imperial dynasty of the Palaiologoi and the Muslim rulers. It seems that special tolerance of the Mongols towards Christianity (even if they were Muslims) played a key role in the change of the principles of the Byzantine marriage policy: it henceforth became possible for the Emperor’s illegitimate daughter to marry a Muslim ruler. This policy affected the marriages of the later period of the fourteenth and fifteenth century between the imperial dynasties of the Palaiologoi and Grand Komnenoi, on the one hand, and the neighboring Turkish rulers, including the Ottomans, on the other.
Сonveying Love: Amor, Caritas, Affectus and Dilectio in the Venerable Bede’s Ecclesiastical History of the English People and Its Old English Version
Authors: Vershinina Yulia
Published: January 2023

This article is devoted to the analysis of the semantic and functional features of the words used by the Venerable Bede in Ecclesiastical history of the English people (as well as in his other historical and hagiographic works) to convey the emotional component of the relationship between its characters, namely the concept of love, and the specifics of its translation into Old English. We have identified and analyzed the Latin words used by the author of Ecclesiastical history to express the concept in question. We came to the conclusion that the main term conveying the concept of love in the most general sense was the word amor. It was used most often by the author of Ecclesiastical history and was a neutral word indicating the presence of a certain attitude / commitment / inclination of one person to another, or to an inanimate object. A positive or negative connotation was imparted to it by the object of love or the character love had. Caritas indicated charity as a Christian virtue, which consisted not in experiencing a special attachment to someone or something but in keeping the commandments. Bede used the word affectus to indicate a feeling of love that was experienced more strongly than was customary in a given situation or between certain categories of people. By dilectio, he apparently understood love for God, which was supposed to underlie relations between Christians, love as a Christian virtue. The translator, unlike the Venerable Bede, used only one word to convey the identified nuances of perception of love. He coped with this task by using linguistic and grammatical transformations. We have identified a certain similarity in their perception of the concept under consideration. At the same time, the translator, apparently, perceived love between secular people as existing not only at the level of feelings, but also at the level of actions. This is evidenced by his use of the combination of the Old English verb lufian and the noun lufu. The same feature, in his opinion, was also characteristic of the feeling described by Bede as affectus. He firmly linked caritas with love for Christ. In addition, the translator mentioned love where it was not used in the Latin text of Ecclesiastical history to mitigate Bede's criticism of the representatives of the Celtic Christianity, which was one of the tasks that he faced when creating the translation.
Influence of Confessional Policy of the Russian Empire on Marriage and Family Relations of Transcaspian Turkmens
Authors: Ilya Aminov
Published: January 2023

The subject of the study is the transformation of marriage and family relations of Transcaspian Turkmens under the influence of the confessional policy of the Russian Empire, which included the territory of Transcaspia in its borders in the last third of the XIX century. The use of concrete historical, comparative legal, structural and systemic methods in the study allowed us to draw conclusions relevant for filling historical and legal gaps in Russian-Turkmen relations. Despite the tolerant attitude of the imperial authorities and even the support of some Muslim-legal (religious-ceremonial, family-household and moral) prescriptions, Sharia could not subdue all aspects of Turkmen life and replace customary law (adat), which played a major role in all periods of development of Turkmen society. Sharia were clarified and applied. During the imperial period, thanks to the activities of the Russian administration and the central government, the jurisdiction of Muslim law expanded significantly; it received a judicial tribune in the form of such a centralized body as the Extraordinary Congress of People's Judges, with the help of which some guiding principles of both Adat and Sharia were clarified and applied. The rapidly changing socio-economic situation caused by the close interaction of traditional Turkmen institutions with Russian state bodies (changes in the economic and lifestyle of the local population, binding to market relations, non-belittling of the role of Islam and Adat in its spiritual life, their compromise combination with the general laws of the empire, the practice of improved forms of popular justice) led to a change in the traditional legal consciousness of the Turkmen. The desire of the imperial center and the Russian administration of Transcaspia for the regulatory and legal regulation of life in the family, marriage and other spheres allowed this people to gradually integrate into the all-imperial state and legal space, while preserving stability, family and religious values.
The Award System of the Great Patriotic War in the Ethno-Political Dimension
Authors: Bezugolniy Aleksej
Published: January 2023

The system of individual and collective rewards and awards for courage and valor shown in battle had a huge moral and educational impact on military personnel. During the Great Patriotic War, the realization of the special value of the award system for the formation and maintenance of high moral and political motivation of soldiers and commanders came gradually. The expansion of the nomenclature of awards, the extension of the rights of awarding and awarding awards to an increasingly wide range of commanders, led to the fact that the number of awardees grew exponentially during the war years. The award policy of the Soviet state had its own ethnic dimension, which has so far been studied only in fragments. Meanwhile, of course, it is not only a well-defined and important aspect of the national policy implemented through the system of awards.

Russians as Seen by Spanyards: Two Embassies of Piotr Potiomkin to Spain (1667—1668 and 1681)
Authors: Védyushkin Vladimir
Published: January 2023

The article deals with one of the aspects of the history of first Russian embassies to Spain, in 1667—1668 and 1681, headed by Piotr Potiomkin, — with the perception of Russia and Russians by Spanish politicians who negotiated with diplomats from Muscovy. This perception is examined in a broad context of the history of both embassies based on an analysis of published and unpublished Spanish sources. The matter of what knowledge and ideas about Russia the Spanish diplomats could rely on when they made decisions on organizing the reception of the embassy, the ceremonial of the royal audience, etc. is being investigated. In this regard, narrative and cartographic sources about Russia available in the Seventeenth Century Spain are examined. It can be traced how the lack of interest in Russian proposals influenced the attitude towards Potemkin and his companions. Some information is provided about the conflicts that arose. Visual sources on the history of the embassy of 1681 are also analyzed.
Ashgabat Before and After 1881: Features of the Russian-Asian Town
Authors: Muradov Ruslan
Published: January 2023

The article deals with the East — West opposition in the structure of the Central Asian colonial cities on the example of Ashgabat. Data on its pre-colonial history are given, little-known pages of the formation and development of a military settlement on the site of the modern capital of Turkmenistan in the late 19th and early 20th centuries are highlighted. The thesis is affirmed that each Russian settlement in the native environment was a cultural enclave subject to constant pressure from the dominant autochthonous culture. Ashgabat is characterized as a typical double city with a clear division into Asian and European parts, like other cities in the Turkestan region. During a short historical period, Ashgabat has undergone a radical transformation from a small Turkmen settlement into a typical Russian-Asian city with all its negative and positive features. In just 140 years, it has evolved from a little-known settlement into the capital of an independent state that has achieved visible results on the path of decolonization.
Integration of the Central Asian Countries in Current Stage: Dynamic, Stage, Problems and Perspectives
Authors: Koichumanova Cholpon
Published: January 2023

The article is devoted to the study of the role of integration processes in solving a number of the most important problems facing the Central Asian states at the present stage. Considering the theoretical foundations of economic integration as a phenomenon of modern development of states, the dynamics of its development in the region, the authors come to the conclusion that so far the countries of the region have not overcome the first stage of its formation, however, in the modern development of the states of the region, the unifying, not the separating principle prevails. In order to prove the crucial role of integration in the modern development of the countries of the region, the article considers the main directions that could deepen and expand integration processes. The article highlights the idea that in modern conditions, a necessary condition for the activation of integration processes is the development of a clear strategy of interstate interaction that meets the interests of all states in the region without exception. Statistical materials characterizing the degree and dynamics of economic cooperation of the Central Asian countries during the period of independence, articles by Russian and Central Asian experts, which characterize the integration processes, as well as the level and direction of their relationships, were used as sources for writing this article. Based on a systematic analysis of the revealed factual data, an attempt was made to determine the areas of cooperation that are most promising at the present time.  The material of the article was analyzed using a number of special methods, among which the historical-comparative method was used most of all, which made it possible to reflect the degree of participation of the countries of the region in integration processes. Using the historical-genetic method, the main stages and dynamics of the interrelations of the Central Asian countries were analyzed.
No Embassy, no Ambassador: a New Kind of Relationship between USSR and Spain in Post-War Times
Authors: Puigsech Farràs Josep
Published: January 2023

This article analyses how the beginning of the Spanish post-war period impacted in diplomatic relations between Spain and USSR. The Republican defeat in the Spanish Civil War forced the rupture of diplomatic relations between these countries. The Communist Party of Spain played the unofficial role of Spanish representative in front of the USSR from April 1939. For this reason, new diplomacy relationship started in the Spanish post-war period: unofficial character, new actors, a huge desire to overthrow the Francoist Spain and a legitimizing lecture about the Second Republic and the Spanish Civil War.
Perestroika in the USSR: Ibero-American Perception
Authors: Grantseva Ekaterina
Published: January 2023

The time of perestroika in the USSR is an ambiguous period, giving rise to numerous discussions both in Russia and abroad. The perception of Soviet perestroika on the part of Spain and the countries of Latin America has a special specificity. This specificity is due to the previous history of the development of relations between the Soviet Union and the Ibero-American countries, as well as the hopes and fears associated with the changes taking place in the USSR. On the one hand, this era witnessed the mutual growth of interest between the USSR and Spain, the intensive development of bilateral relations, cultural and scientific ties. On the other hand, representatives of Latin American countries, in their own way and sometimes painfully, perceived the changes taking place in the USSR. Of course, even here it was impossible to move away from the widespread enthusiasm for Gorbachev and his ideas that swept the world. But there were also many reasons for pessimistic views, first of all, they concerned the prospects for the socialist model of development. Among the negative aspects that influenced the image of perestroika that had taken shape in the Ibero-American countries were disillusionment with the USSR as a counterbalance to the United States, experiencing the economic consequences of Gorbachev's policy, and the idea of the collapse of the Soviet model of socialism. Among the positive ones are the end of the Cold War, new thinking and democratization, hopes for reformatting, but the preservation of the socialist model. At the same time, this period left a significant mark not only in the development of relations between the USSR and the Ibero-American countries, but also became a bright page in intercultural dialogue.

State Financial Control over Costs of Religious Organisations in Ukraine
Authors: Bilash Oleksandr , Karabin Tetyana
Published: January 2023

The article is devoted to the study of issues of state financial control over the activities of religious organizations in Ukraine through the disclosure of the goals to which such control is directed and the state's intervention in the activities of religious organisations. The analysis was carried out in several directions, which are tools of state influence. First of all, it is a legally defined obligation to keep accounting records by a religious organisation and the requirement to submit financial statements as one of the components of state financial control. Secondly, it is a control over the targeted use of funds that religious organisations can and do receive during the implementation of budget programs. Thirdly, it is the state financial control over the activities of economic entities, which are formed by religious organisations (publishing, printing, production, restoration and construction, agricultural and other enterprises). In each of the cases, the subject of the control activity, control activity procedures and goals that must be achieved as a result of the control procedures carried out by the state bodies differ.

The continuous increase in the speed and load of railway transport operating in a wide range of climatic zones of the Russian Federation creates a need to develop new friction materials with the improved performance properties that can ensure high functioning reliability of the electric switch mechanisms. The paper presents the results of the study of the microstructure, physical, mechanical, and operational properties of a new material for friction inserts based on an iron matrix for the switch gear clutches. The new material composition includes such components as Fe, Cu, BaSO4, SiO2, C, and Zn. The authors propose a technique for selecting materials with the specified performance properties based on the results of the research carried out using the experiment factorial planning. For this purpose, the authors carried out the studies and established a relationship between the values of microstructure indicators, physical, mechanical and operational properties of the materials with different quantitative composition of components. The grain boundary density was proposed as an indicator of the dissipative properties of the material, and the possibility of its application as a structural parameter for evaluating the friction material performance characteristics. To assess the friction material performance characteristics, which determine the possibility of its application as a part of the friction clutches of the electric switch mechanism, the authors proposed a new parameter – the endurance period . Another service property was the deviation of the friction coefficient ƒ values in the range of values of the clamping force of the electric switch mechanism. According to the results of bench tests of a new friction material within the friction clutches of the electric switch mechanism, the authors identified a high wear resistance of the material and the possibility of its use in severe climatic conditions. The proposed testing technique allows predicting the performance properties of new materials at the stage of studying the microstructure based on the obtained dependences, which can significantly narrow the search range.

High-pressure torsion deformation (HPT) is an effective method for transforming the structure of metallic materials, forming a nanostructural state in them, and significantly improving their strength. However, deformation achieved during HPT can be much less than expected due to the slippage. The study of the slippage effect during HPT of various materials is a topical issue. Previously, the authors proposed a simple and illustrative method for assessing slippage and the actual degree of torsion deformation achieved during HPT. Zr–1%Nb alloys, on which many studies of the HPT effect previously have been carried out, are good material for studying the slippage effect during HPT. Therefore, it is possible to compare obtained data with the results of other authors. The paper investigates the HPT impact on the structure and properties of the Zr–1%Nb alloy and demonstrates the slippage effect. The initial disk, prepared for HPT, was cut into two half-disks that were jointly placed on the strikers and exposed to joint HPT for n=¼ revolutions of anvils. The authors evaluated the slippage effect from the view of halves. The study showed that even at the initial HPT stages at n=¼ revolutions, there is a significant slippage of strikers and a sample, and the torsion deformation does not accumulate as expected. The authors analyzed the influence of various HPT modes on the microhardness, structure, and phase composition of the Zr–1%Nb alloy. The study shows that, despite the slippage effect, the Zr–1%Nb alloy is strongly hardened during HPT for one revolution (n=1) and HPT with n=10; the microhardness and tensile strength increase significantly, and up to 90 % of high-pressure ω-phases is formed in the sample. The authors conclude that during HPT, the deformation is implemented not by simple torsion but by the more complex modes.

Magnesium-rich aluminum alloys with small scandium additives are widely used in many branches of modern industry due to the high level of their mechanical properties. However, the issue of low thermal stability of Al3Sc particles, which does not allow performing deformation processing of this group of alloys at a temperature above 400 °С, continues to be relevant. Hafnium addition can become one of the ways to solve this problem as hafnium forms a shell around the Al3Sc particles and, due to the low diffusion coefficient in the aluminum matrix, reduces their coagulation rate. The paper studies the influence of addition of 0.2 % and 0.5 % Hf on the electrical conductivity and the process of supersaturated solid solution decomposition, as well as on the size and quantity of nanoparticles in the 1570 magnesium-rich aluminum alloy at its thermal treatment. The authors studied the kinetics of supersaturated solid solution decomposition in the 1570, 1570–0.2Hf, and 1570–0.5Hf alloys by the electrical conductivity measuring and constructed C-curves describing the supersaturated solid solution decomposition in the studied alloys in the temperature range of 260–440 °С. Besides, using transmission electron microscopy, the strengthening nanoparticles of the 1570 and 1570–0.5Hf alloys were studied during heating to 370 °C and 4-hour soaking. The study showed that hafnium addition significantly slows down the supersaturated solid solution decomposition in the 1570 alloy. The authors identified that in the alloys with hafnium additives, the supersaturated solid solution decomposition is the most intense at a temperature of 350 °С, and in the alloys without hafnium – at a temperature of 430 °С. The transmission microscopy data confirm that the 1570 alloy without hafnium contains 3–4.5 times more nanoparticles than the 1570–0.5Hf alloy.

The pandemic caused by Coronavirus-19 Disease (COVID-19) is having negative effects on healthcare workers (HCW) mental health due to the tremendous amount of stress to which they are exposed to. We aimed to assess the number of mental health outcomes among HCW treating patients with COVID-19. This cross-sectional study collected demographic data and mental health measurements from HCW in different hospitals using an online questionnaire. Participants were asked to complete the 9-item Patient Health Questionnaire (PHQ-9), the 7-item Insomnia Severity Index (ISI), and the 7-item Generalized Anxiety Disorder scale (GAD-7). One hundred and forty-one participants with a mean age of 30.6±25 years and a sex ratio of 0.3 completed the online questionnaire. Participants from major university-hospital centers of northern Tunisia were divided into two groups: 78% medical and 22% paramedical staff. Twenty-two participants (15.6%) had a chronic disease, and 21 (14.9%) had a history of depression. Nineteen (13.4%) of the participants were infected with COVID-19. Thirteen percent of participants experienced the same anxiety level as the first-time taking care of COVID-19 patients, while 65% were rather an at ease compared to the first time. Forty-seven percent of participants felt the need for psychological support, and 16.7% of them had consulted a psychiatrist. Mild depression was detected in 14.1% of cases, moderate depression in 4.2% of cases, and severe depression in 2.1% of cases. As for anxiety, 36.1% of participants suffered from mild anxiety, 14.9% from moderate anxiety, and 4.9% from severe anxiety. Mild insomnia was detected in 44.6% of cases, moderate insomnia in 14.9% of cases, and severe insomnia in 9.9% of cases. Female gender (depression: P=0.05; anxiety: P=0.05; insomnia: P=0.02), having friends or relatives with COVID (depression: P=0.01; anxiety: P=0.05), psychiatric illness (depression: P=0.05; anxiety: P=0.01; insomnia: P=0.01), and chronic disease (depression: P=0.02; anxiety: P=0.03) were significantly associated with more severe mental health symptoms. Tunisian HCW experienced psychological burdens and a high rate of anxiety, depression, and insomnia. HCW should be protected in order to promote mental well-being.

Vitamin D deficiency plays an important role in the development of various diseases, including cancer. Regarding the high prevalence of breast cancer and vitamin D deficiency in Iran, this study aimed to investigate the relationship between vitamin D deficiencies and prognostic factors in breast cancer. This descriptive-analytical cross-sectional study was performed from March 2015 to March 2017 at Imam Reza hospital in Kermanshah city, Iran. 145 breast cancer patients with pathologic confirmation and before the neoadjuvant or adjuvant treatments were included by simple and convenient sampling. Serum 25(OH) D levels were measured in all patients before receiving treatment. The collected data were analyzed by using SPSS software (version. 20), and the relationship between the levels of 25(OH) D and the studied factors was assessed by inferential statistical tests in each group. The results showed that there was a statistically significant direct relationship between serum vitamin D levels and some factors, including age, ER, and PR, but a significant inverse relationship was observed between serum vitamin D levels and the level of ki67 and metastasis. There was no statistically significant relationship between the mean serum level of vitamin D and tumor grade and P53 receptor, but high levels of vitamin D were associated with low-grade tumors and P53 negativity. According to the findings, lower levels of vitamin D can be associated with higher levels of ki67 and P53, higher-grade breast cancer, a higher rate of metastases, as well as lower percentage of hormone receptor positivity.

Investigating the Relationship between DTS and syntax score (SxScore) as an indicator of complexity and severity of coronary artery disease in patients with intermediate and high Duke Score. This cross-sectional study was conducted at the exercise test unit of Heshmat Hospital in Rasht from September 2017 to December 2018. Among 1033 patients that passed exercise cardiac stress testing (EST), 118 patients who had positive exercise testing for CAD were enrolled. Coronary angiography was performed, and SxScore, a marker of CAD complexity, was determined. The relationship between DTS and SxScore was then evaluated. The data were analyzed by SPSS version 21. The risk of positive EST raised age more than 61 years (OR=1.072; 95%; CI=1.046-1.099), Hypertension (OR=3.235; 95%; CI=2.097-4.992), Hyperlipidemia (OR=2.109; 95%; CI=1.371-3.242) and Diabetes Mellitus (OR=2.15; CI=1.22-3.14). The presence of the following factors reduced positive EST: female (OR=0.377;95%; CI=0.133-1.068), retired (OR=0.128;95%; CI=0.045-0.361). The results of the present study showed that there was no significant difference between the degree of coronary artery involvement based on syntax with Duke scores (P=0.328). Although both DTS and Syntax scores are useful in evaluating coronary artery disease, there isn't a significant relationship between these scores, and they don't coincide. In other words, we cannot use DTS to predict the Syntax score.

Published: January 2023

The novel Coronavirus can cause a vast range of symptoms, among which the most famous is respiratory system complications. Brucellosis is a highly contagious zoonotic disease, especially in endemic areas such as Iran. The disease, initially revealed with nonspecific symptoms, shows similar manifestations to SARS-CoV-2 disease. A 37-year-old woman presented with severe pain and swelling of the right inguinal area a week after working in a garden. Brucellosis treatment was initiated, and the patient was transferred to the COVID ward and received COVID medical therapy. The patient's pain reduced, and she was discharged and informed of the warning signs or any condition change. Owing to the high prevalence of COVID-19, other infectious diseases may be neglected. This case is a reminder to clinicians that the co-infection of SARS-CoV-2 and other diseases such as brucellosis may occur and differential diagnoses should be considered, especially for endemic diseases.

Ticks transmit a variety of pathogens, including viruses, spirochetes, bacteria, rickettsia, protozoa, filarial nematodes, and others, only behind mosquitoes, that result in human and animal mortality. Tick infestation poses severe threats to livestock farming, which plays a crucial role in Pakistan's rural economy. However, more research needs to be done in the study area of Pakistan on the diversity of tick species and the pathogens carried by ticks. This study aimed to determine the prevalence of ticks in Pakistan. A total of 226 tick specimens were collected from 1023 animals (136 sheep and 147 goats, 329 cows, 411 buffaloes), examined in the study area. It showed that total eight species belonging to four genera were collected and identified. The identified species were Dermacentor marginatus, Hyalomma anatolicum, Hy. Dromedarii, Rhipicephalus sanguineus, R. turanicus, R. appendiculatus, R. annulatus and Haemaphysalis punctate. Among collected tick species, Hy. anatolicum was the most widely distributed tick species. The maximum tick prevalence was recorded on buffaloes 87 (38.49%) followed by goats 53 (23.45%), cattle or cows 51 (22.56%) and sheep 36 (15.92%). Male animals were least infested with tick species than female animals while maximum female ticks were recorded in the study area than male. In order to control ticks in the study area, appropriate methods are required.

Published: January 2023

Unhealthy nutrition attitudes and behaviors are quite common among women. The development of such behaviors involves a high risk for existing health conditions of slightly obese and obese individuals. The way to a better quality of life is through doing regular physical activity, having a healthy diet, and changing eating attitudes. In this context, this study was conducted to examine the nutritional status and eating attitudes of women who applied to a private clinic and exercised. A total of 111 women between the ages of 18-45 who applied to a private nutrition and diet clinic in Karabük province in Türkiye and engaged in regular physical activity (at least 150 minutes per week or more) were included in the study. The data were collected using a questionnaire including the participants’ demographic data, anthropometric measurements, 3-day food consumption records, physical activity habits and Eating Attitude Test (EAT-40) scale. The measurements were performed with the Inbody 120 device, which performs detailed body analysis. SPSS 23.0 (IBM SPSS Statistics) was used in the analysis of the data. The “Independent Sample-t” test (t-table value) was used to compare the measurement values of two independent groups. Eating attitudes of women differ according to age, educational status and BMI groups. Of the women with normal eating behavior, 50.6% are married, 46.1% are between the ages of 30-34, 49.4% are university graduates, and 61.8% are within the normal BMI range (P

Los sistemas silvopastoriles representan una alternativa para la producción de forraje para ganado y leña, la reducción de la degradación del suelo y la diversificación de la producción agropecuaria. El objetivo de este estudio fue identificar las áreas potenciales para establecer sistemas silvopastoriles conformados con Pinus lawsonii y dos gramíneas forrajeras Eragrostis curvula y Chloris gayana, en el estado de Michoacán, México, en áreas con suelos degradados. Se modeló ladistribución potencial de las tres especies según sus requerimientos de elevación,precipitación media anual, temperatura media anual y tipo de suelo. Posteriormente se intersectaron los polígonos de cada especie para obtener las áreas potenciales. Por último, se intersectaron dichas áreas con la capa de suelos degradados. Lasáreas potenciales para sistemas silvopastoriles con P. lawsonii y E. curvula se concentraron en la porción michoacana del Eje Neovolcánico, sobre una superficie de 190 918 ha en 61 municipios, mientras que con P. lawsonii y C. gayana se encontraron en el Eje Neovolcánico y la Sierra Madre del Sur, sobre una superficiede 329 546 ha de 81 municipios. Además, el 60.8% de la superficie es apta para P. lawsonii y E. curvula. El 55.4% de P. lawsonii con C. gayana se encuentran sobre suelos con algún grado de erosión. Los resultados indican potencial alto para establecer sistemas silvopastoriles con estas especies en Michoacán, lo cual podría contribuir a la recuperación de suelos erosionados y a la provisión de forraje para el ganado y leña para habitantes rurales.

Published: January 2023

La normalización internacional y nacional en la formación de emprendedores resulta funcional y necesario para enfocarla en uno de los objetivos de la responsabilidad social; así como la diferencia entre ellas, con el propósito de transmitir a los empresarios la importancia de conocerlas y aplicarlas desde el origen del proyecto de negocios. Esto permitirá que se fomente una cultura empresarial interesada en las Normas Oficiales Mexicanas (NOM) y demás ordenamiento jurídicos, dando apertura a la aceptación en cuanto al carácter coercitivo y heterónomo de la legislación; lo que hace necesario realizar cambios en la enseñanza de la asignatura de Derecho, en las Licenciaturas de Administración, Negocios, Contabilidad. Se resalta la conveniencia de enfocar la enseñanza de esta disciplina enfocado al desarrollo humano, valores éticos, derechos humanos y bioética, a efecto de sensibilizar a los futuros empresarios de los beneficios que tendrá constituir una empresa con una visión de ser socialmente responsable y apegada al desarrollo sustentable.
