Objectives: Apigenin and parthenolide as natural products have potent antioxidant and anti-inflammatory outcomes that could make them a perfect option for endometriosis therapy. This study aimed to determine the effects of apigenin and parthenolide on created endometrial implants in a rat model of endometriosis.
Methods: Thirty-nine mature, female Sprague-Dawley rats were assigned randomly to six experimental groups four weeks after endometriosis induction. Group 1 (n = 5): Control (CTRL) that opened and closed the abdomen; Group 2 (n = 6): Peritoneal and ovarian endometriosis (POE) + drug-free; Group 3 (n = 7): POE+ Apigenin (APG) (50 mg/kg); Group 4 (n = 7): POE+ Parthenolide (PTL) (10 mg/kg); Group 5 (n = 7): POE+ Apigenin (APG) (50 mg/kg) + Parthenolide (PTL) (10 mg/kg); Group 6 (n = 7): POE+ DMSO. An endometriosis model was created, and histopathological analysis and biochemical evaluation were performed. Serum and peritoneal levels of pro-and-anti-inflammatory cytokine, and oxidative stress of implant tissue were measured.
Results: Serum IL-37 levels decreased significantly in the APG-treated group compared to the drug-free group (p = 0.016). The peritoneum and ovary endometriosis histopathologic scores were significantly lower in APG-treated (p = 0.001) and PTL-treated (p = 0.001) groups in comparison to the drug-free group. The oxidative stress index (OSI) values were increased statistically significantly in ovary endometriosis tissue in the drug-free group, (p = 0.001). However, compared to the drug-free group, OSI values decreased statistically significantly in the APG-treated group (p = 0.003). Conclusions: The application of apigenin caused a decrease in oxidative stress and an improvement in histopathological grade. Apigenin may be a novel therapeutic agent for the treatment of endometriosis.
Recenzja książki: James Evans, The history and practice of ancient astronomy, Oford University Press, 1998.
Authors: Dylewski Jarosław
Published: January 2023

Professor James Evans is a physicist working an University of Pudget Sound in the USA. His reseatch is focused on ancient astronomy and application of that knowledge. He also successfully attempted to build gnomon, astrolabe or analemna – instruments used in antuiquity and medieval times to make observations of celestial bodies. In his work, The History and Practice of Ancient Astronomy, professor Evans introduces the reader to the evolution of astronomical knowledge, from the simplest observations made by farmers or sailors to complex astronomical models and calculations of asronomers such as Ptolemy. The author focuses mostly on ancient Babylonians and Greeks as he believes that their input on that field was most significant and the apex of ancient astonomy was Almagest by Ptolemy (one may criticise author’s thesis that Copernicus’ work was mostly a repetition of dicoveries made by the Greek astronomer with addition of the heliocentric theory of the universe). Next, professor Evans speaks of celestial pheres, stars and planets, also explaining the particular theories related to them. What is interesting is the author’s approach to ancient testimonies. He does not only ask what we learn from ancient scriptures, tablets and other findings, but also how do we learn it. Language and phrasing in this book are clear enough to unsderstand for those without background in physics or ancient languages. Priceless addition to this work are numerous illustrations placed on page margins although it happens sometimes that figure to which the current text refers to is located several pages away. This requires te reader to pay close atention to figure numbers. The word ‘practice’ mentioned in this book’s title points to one of the most importants assets of professor Evans’ work. Apart from sharing the knowledge with the reader the author shows him how to use that knowledge to verify the author’s hypotheses and how to make the observations the way they were mentioned in the ancient texts. The History and Practice of Ancient Astronomy shows the reader how to make observations of daily and annual movement of the Sun, how to determine latitude of a particular place or how to measure the approximate distance of Sun or the Moon form the Earth. Each of the subchapters is ended by list of excersises that allow to test the freshly gained knowledge. On top of that the author has also provided schematics which allow the reader to build his own astrolabe – an instrument commonly used by Arabic and European astronomers. Some might feel surprised that footnotes have been moved to the end of the entire book which makes it a little difficult to track loci of the texts quoted by the autor. Apparently it is a compromise made for sake of clarity of the lecture and general estethic feeling of the book. Without any doubt The History and Practice of Ancient Astronomy is a position worthy of being recommended not only to enthusiasts of physics and astronomy but also of ancient science and culture.
Women Empowerment and Demand for Sexual and Reproductive Health Services
Authors: Francke Pedro , Quispe-Ortogorin Diego
Published: January 2023

We analyze the effect of women's empowerment on their demand for reproductive and sexual health services. In particular, we explore their use of modern contraceptive methods, if the women have had an HIV screening and if they have made a health consultation after experiencing symptoms of sexually transmitted infections. We calculate four women empowerment indexes, proxies to the economic dimension of empowerment, the freedom of movement to visit family or friends, the respect of their couple to their opinions, wishes and rights, and the ability of women to decide about their health. We found that freedom of movement for women at a medium level increases the probability of using modern contraceptive methods as well as screening for HIV/AIDS and that the couple's respect for the views and rights of women positively influences the use of modern contraceptive methods. However, women´s autonomy to make decisions regarding their health is the empowerment indicator with the most robust results on the use of sexual and reproductive health services, increasing the probability of using modern contraceptive methods and consulting for STI symptoms.

Published: January 2023

This study aimed to investigate aspects of face-to-face and distance learning and create a model of distance education for university teachers. For this, theoretical methods of comparison, analysis and symbiosis were used. As a result of the study, differences in the characteristics of various types of education and the possibilities of creating an effective programme of distance education for university teachers were revealed. A model has been developed for organising distance learning in higher education. This model can be applied to any university curricula. As a recommendation, the authors put forward several proposals for changing the grading system: adopt criteria-based assessment and, based on criteria-based assessment, carry out educational monitoring.

Published: January 2023

Foster (1932) performed a mathematical census for all connected symmetric cubic (trivalent) graphs of order n with n ≤ 512. This census then was continued by Conder et al. (2006) and they obtained the complete list of all connected symmetric cubic graphs with order n ≤ 768. In this paper, we determine the total vertex irregularity strength of such graphs obtained by Foster. As a result, all the values of the total vertex irregularity strengths of the symmetric cubic graphs of order n from Foster census strengthen the conjecture stated by Nurdin, Baskoro, Gaos & Salman (2010), namely ⌈(n+3)/4⌉.

Authors: Ceylan Merve
Published: January 2023

This research was conducted to examine the relationship between the trait anxiety levels of national sailing athletes and their mental toughness levels and to investigate the effects of some variables on the athletes' trait anxiety and mental toughness levels. The research universe consists of national athletes competing in different disciplines affiliated with the sailing federation. The sample comprises 32 national athletes (Kitesurfing, windsurfing, and centerboard classes) who voluntarily participated in the research. In addition to the Demographic Information Form, the "Sports Mental Toughness Inventory" and "State-Trait Anxiety Inventory" were used in the research. As a result of the analysis of the data, it was seen that the confidence level of the male athletes was higher than the female athletes, the control levels of the female athletes were higher than the male athletes, and the confidence levels of the kitesurfing athletes were higher than centerboard and windsurfing athletes. In addition, there was a positive and moderate relationship between the age of the athletes and the duration of doing sports and competition. At the same time, there was a negative and moderate relationship between age and the control sub-dimension and between confidence and the control sub-dimension.
A problemática ambiental e os discursos de Responsabilidade Social das Empresas
Authors: Saldanha Jânia Maria Lopes , Mello Rafaela da Cruz
Published: January 2023

O presente artigo tem como objetivo analisar, pelo método de abordagem hipotético-dedutivo, as apropriações discursivas da questão ambiental, ao demonstrar que tal domínio do discurso, por parte de poderes hegemônicos, apenas confere ao problema uma roupagem ecológica, enquanto serve, na realidade, para as estratégias e jogos de poder político e econômico. Diante de tal premissa, a questão que se almeja responder é: ante a apropriação discursiva da problemática ambiental pelos atores globais econômicos, quais são os riscos do discurso de responsabilidade social das empresas. Ao fim do trabalho, conclui-se que, assim como a premissa de desenvolvimento sustentável, a proposta de responsabilidade social das empresas ocorre sob a lógica de uma racionalidade econômica dominante e não ambiental. O grande risco desse discurso é o de mascaramento das atividades de uma empresa por meio do processo de  greenwashing (ou lavagem verde), ou seja, uma aparência de preocupação ambiental para minimizar as reais atividades empresariais.

Published: January 2023

Agrobacterium sp. I26 and Agrobacterium sp. I30 are bioremediation agent that can be used as functional bacteria in biofertilizers. The storage of these bacteria requires carrier. Not all carriers can support bacterial viability, so it was necessary to examine carrier formulas as basic ingredients for biofertilizers which the quality standards based on the Minister of Agriculture Regulation No. 70/2011. This research aimed to: (1) study the viability of Agrobacterium sp. I26 and Agrobacterium sp. I30 in some carrier formulas; and (2) obtain the best carrier formula to support the viability of Agrobacterium sp. I26 and Agrobacterium sp. I30. Research design was factorial using completely randomized design (CRD) as the based design, consisting of 2 factors: 1) Carrier Fornula (C): C1; C2; C3; C4; C5, 2) Bacteria (I): I1; I2; I3, so there were 15 treatment combinations each was repeated 4 times, thus there were 60 experimental units. The results showed that Agrobacterium sp. I26 has better viability than Agrobacterium sp. I30 during 90 days incubation period. The best bacterial viability with total bacterial as the indicator was C4 carrier formula: 74 x 10­13 cfu.g-1 for Agrobacterium sp. I26 and C3 carrier formula: 155 x 1012 cfu.g-1.
THE ESTIMATION OF THE EFFECT OF COKE, OBTAINED WITH PARTICIPATION OF VOLUME-MODIFYING ADDITIVES, ON THE TECHNICAL AND ECONOMIC INDICATORS OF BLUST FURNACE SMELTING
Authors: Zelenskii O.
Published: January 2023

The article deals with the effect of the coke resistance index CSR (Coke Strength after Reaction) on the technical and economic indicators of the blast furnace process. It is shown that in the production of metallurgical coke using volume-modifying additives in the amount of 0.25% by weight of the coal load, its strength improves, in particular, index CSR. As a volume-modifying additives, α-Al2O3 electrocorundum and α-SiC carborundum with a particle size of <45 μm and vibromilenum α-SiC carborundum with a particle size <12 μm were used.

Due to the introduction of fine powders of electrocorundum and carborundum into the coal charge, the maximum increase in the coke post-reaction strength index (CSR) by 7.6% was obtained.

The influence of changes in individual indicators of coke quality on its consumption and productivity of the blast furnace was assessed in accordance with the guidance document of the metallurgical division of Metinvest Holding LLC. This document contains a detailed methodology for use in analyzing fluctuations in specific coke consumption and throughput of blast furnaces influenced by changes in blast furnace process parameters (by factor analysis). This technique is based on quantitative relationships between changing parameters (factors) and specific coke consumption (blast furnace productivity).

There has been made an expert technical and economic assessment of the feasibility of introducing 0.25% fine powdered α-Al2O3 and α-SiC powders into the mixture from the point of view of blast-furnace production with pulverized fuel injection technology. The results show that, despite the increase in the cost of coke with the introduction of volume-modifying additives into the mixture, a reduction in the cost of iron can be achieved due to the expected reduction in the specific consumption of coke due to an increase in its post-reaction strength.
REFINEMENT OF THE FOUR-COMPONENT SYSTEM MgO – CaO – Al2O3 – Cr2O3 SUB-SOLIDUS STRUCTURE INCLUDING THE Сa6Al4Cr2O15 COMPOUND

Published: January 2023

The results of theoretical calculations of the subsolidus structure of the four-component system MgO – CaO – Al2O3 – Cr2O3 are presented, taking into account the three-component compound Сa6Al4Cr2O15. Thermodynamic and geometric topological analysis methods were used to establish stable conodes in the specified system. When dividing the concentration tetrahedron MgO – CaO – Al2O3 – Cr2O3 into elementary ones with the involvement of a geometro-topological analysis, it is possible to make an unambiguous closure to the elementary tetrahedron of faces with incident edges (connodes) through a common vertex. The use of this method allows to minimize the number of necessary thermodynamic calculations. The tetrahedra of the MgO – CaO – Al2O3 – Cr2O3 system, taking into account the stable phases, is caused by the presence of three "internal" conodes passing through the three-dimensional space of the concentration tetrahedron: Сa6Al4Cr2O15 – MgO; MgCa3Al4O10 – CaCr2O4, CaCr2O4 – MgAl2O4, which determine the presence of 14 elementary tetrahedra in the subsolidus region. The lengths of conodes and volumes of elementary tetrahedra were calculated taking into account barycentric coordinates and elements of Euclidean geometry. The phases included in the composition of the tetrahedron with the largest relative volume and the smallest asymmetry CaCr2O4 – СaAl2O4 –MgAl2O4 – MgO (185.6 ‰ and 2.55, respectively) have the highest probability of existence in the system, which will allow the development of a sustainable technology for creating composite materials based on calcium aluminochromite cement, with periclase as an aggregate, without special techniques dosage of initial components. At the same time, in the event of a violation of the technological process, magnesium aluminate spinel will be synthesized in the composition of the unformed material, which will not lead to deterioration of the performance characteristics of the composite used. It should be noted that elementary tetrahedra with a high degree of asymmetry, which require appropriate dosage accuracy when predicting the phase composition of synthesized composite materials, are located in areas of the system that are not technologically advantageous from the point of view of obtaining unformed refractories based on special binder materials, and are interest for materials scientists in the ceramic and refractory industries.

Biotechnological methods can be used in dairy cow reproduction to increase reproductive potential and improve economic outcomes of milk production. Biotechnological methods widely used in reproduction include artificial insemination and embryo transfer, and more recently insemination with sexed semen, which makes it possible to control the sex of the offspring. This study presents an analysis of the effectiveness of the use of sexed semen in a selected herd of dairy cows. The results confirmed the effectiveness of sexed semen at increasing births of female calves. Sexed semen was most effective among heifers. In that group the fewest insemination doses were required for conception (1.54), and pregnancy after the first insemination procedure was noted in 52.2% of cases. The values of selected fertility parameters (calving-to-first-service interval, service period, services per conception, and rate of conception after first service) did not deviate significantly from recommended values in cows inseminated with sexed and unsexed semen. Among the group of cows inseminated with sexed semen, fertility parameters were significantly more favourable than in the group inseminated with conventional semen.

As research materials were used for statistical compilations of the Ministry of Health of the Russian Federation and Federal Research Institute for Health Organization and Informatics of Ministry of Health of the Russian Federation “The Incidence of adult and child population of the Russian Federation”. To analyze the incidence, we used the calculation of dynamic series indicators (rate of increase – decrease, index of growth) and the method of ranking. As a result of the analysis of the incidence of the adult population, it was revealed that there is no dynamics of the indicator in the country as a whole. However, this trend is not observed in all regions of the Russian Federation, for example, the most significant increase was recorded in the Republic of Kabardino-Balkaria (+77%) and in the Leningrad Region (+46%). Analysis of the incidence of the adult population by ICD‑10 disease classes indicates an increase in the incidence of diseases of the circulatory system (+42%), endocrine, nutritional and metabolic diseases (+41%), neoplasms (+18%), diseases of the respiratory system (+12%) and diseases of the digestive system (+4%).As a result of the study, the following years were marked with a significant increase: 2009 (National project “Health”), 2013 (National programme “Modernization of Health Care System”) and 2016 (National programme “Medical examination of the population”). Changes in the incidence indicators correlate with the implementation of national projects and programs, since they are aimed not only at the treatment and prevention of diseases, but also at their detection.

We studied the practice of transfusion therapy for patients at the Pirogov National Medical and Surgical Center, who were diagnosed with irregular antibodies to red blood cells (RBC) in 2020. Among hospital patients, the part of such immunized persons was 1,62% (200 people). Of these, the selection of donor RBC was performed in 29 (14,5%) patients. 45 cross-matching procedures were performed, which involved 177 units of RBC. 121 units were found compatible and 56 – incompatible. Of 29 patients with matched blood, transfusion of matched RBC was received by 14 (48,3%) people. They received 54 units of RBC compatible in the indirect antiglobulin test. In 2 patients, antibodies were detected during transfusion therapy. It is advisable to: a) create a centralized laboratory for federal medical organizations with the possibility of identifying irregular anti-RBC antibodies and individual selection of compatible donors; b) include identification of antibodies in the range of medical services; c) standardize the number of segments of the donor container tube from which RBC can be taken for cross-matching; d) establish the frequency of screening for irregular antibodies while continuing transfusion therapy; e) in a clinic of comparable scale, it is sufficient to maintain a daily supply of RBC in the amount of 2,1% – 2,8% of the annual consumption in order to provide an individual selection of blood for patients with irregular anti-RBC antibodies.

One of the tasks of personalized medicine is to build a new organizational model for providing medical care to patients, based on the selection of individual medical, diagnostic and preventive agents that are optimally suitable for the peculiarities of the body. Modern artificial intelligence methods allow you to solve problems of this type. Purpose. The aim of the study is to construct and apply predictive logistic regression models and decision tree using machine learning techniques to identify patients at high risk of hypertension without the need for invasive clinical procedures. Materials and methods. A formed data set consisting of 395 patient records of Voronezh City Clinical Clinic No. 1 is used. Each record contains patient parameters: patient sex; patient age; body mass index; waist circumference; hip circumference; tobacco smoking status; alcohol use status; systolic pressure; diastolic pressure. Machine learning methods are used to build prognostic models. Results. Two models for predicting the development of hypertension are constructed, characterized by high indicators of classification accuracy: a logistic regression model designed to calculate the patient’s individual risk (accuracy 96%), and a decision tree model designed to predict the patient’s possible disease with hypertension and explain the reasons why this disease can occur (accuracy 94%). Findings. The expediency of using machine learning methods in constructing prognostic models for assessing the state of patients is shown, the possibility of creating a recommendation block based on the obtained models in the remote cardiomonitoring subsystem is indicated.

Классические уравнения мелкой воды выступают альтернативой решению замкнутой системы гидродинамических уравнений в гравитационном поле. Однако классическое приближение не учитывает неоднородность плотности слоя жидкости. В работе рассматривается приближение мелкой воды, обобщённое для описания крупномасштабных сжимаемых течений в поле тяжести со свободной поверхностью. Получена система квазилинейных дифференциальных уравнений, описывающая течение сжимаемой жидкости в приближении мелкой воды. Решения системы находятся в виде линейных волн Пуанкаре на f -плоскости, волн Пуанкаре и Россби на бета-плоскости. Решения получены для новой переменной, нелинейно зависящей от высоты свободной поверхности, поэтому волновая динамика отличается от случая несжимаемой жидкости. Нелинейная динамика найденных волн исследуется методом многомасштабных разложений. Для каждого случая трёхволновых взаимодействий исследованы параметрические неустойчивости и найдены коэффициенты взаимодействия трёх волн в сжимаемой жидкости на бета-плоскости.

Данные радиозондирования атмосферы по температуре воздуха позволяют детектировать в средней стратосфере внезапные стратосферные потепления, а также прослеживать изменчивость температуры во время этих событий на различных уровнях. Полученные результаты свидетельствуют об общем характере изменений озона в ряде зим с внезапными стратосферными потеплениями. Причина этих изменений связана, вероятно, с общими особенностями эволюции полярных вихрей и развития планетарных волн. Рассмотрены временные вариации общего содержания озона и температуры воздуха средней стратосферы в зимний период времени, в том числе во время событий внезапных стратосферных потеплений.
A qualitative insight into the removal of the Australian COVID-19 lockdowns on dogs and cats, and their owners

The majority of Australian dog and cat owners living alone during the first COVID-19 lockdown endorsed the idea that their pet made the isolation easier, reduced feelings of loneliness, and provided companionship. More companionship/attention was also the most highly endorsed way pet owners perceived that the lockdown affected their pets. With the advent of the removal of the first lockdown restrictions and an attempt to return to a ‘COVID normal’ lifestyle, the aim of the current study was to elucidate how pet ownership affected the experience of the easing of restrictions in Australia, and how returning to a state of ‘normalcy’ might have impacted pets. A total of 208 pet owners from Australian states and territories completed an online questionnaire. Participants included 101 dog owners and 107 cat owners. Results revealed that despite official easing of restrictions, ongoing concern of contracting COVID-19 played a role in participant tendency to continue a reduced level of socialising and going outside the house. As a result, there was minimal perceived behavioural and/or emotional impact on most pets. However, for those who were returning to work and/or a life more outside the home, there were reports that both owners and their pets experienced separation anxiety. Participants also reported that they benefited from interaction with pets while working from home, and therefore implementing more pet-friendly policies in workplaces should be considered.
