Published: August 2021

In recent years, biologic therapies such as platelet-rich plasma (PRP) have gained prominence in multiple orthopedics degenerative tendinopathy and ligamental pathology. This research aimed to assess the clinical effectiveness of autologous platelet-rich plasma injection in cases of recalcitrant plantar fasciitis (RPF) over a long period.

A prospective observational study was performed on RPF that did not experience pain relief after three months of conservative therapy. Under sterile conditions, inject approximately 3ml of platelet-rich plasma mixed with 0.5ml lignocaine into the maximum tender point of the heel. Visual Analogue Score for Pain, the American Orthopedics Foot, and Ankle Society (AOFAS) Ankle, and Hind Foot Score at one month, three months, six months, one year, and two years after injection.

A total of 60 patients of RPF which 23 (38.33%) were male, and the rest 37 (61.66%) were female. The mean age was 45 ± 7.25 and the mean duration of symptoms was 7.4 ± 2.1months. The mean VAS score was 7.92 ± 1.2 at pre-injection, was progressively reduced post-injection to 5.61 ± 1.56 at one month, 3.1 ± .83 at three months, and 2.4 ± .68 at six months and remained at low level 2.5 ± .92 at one year and 2.7 ± .56 at two years. The mean AOFAS score was 56.92 ± 13.24 at pre-injection, was progressively increased post-injection to 66.41± 10.26 at one month, 78.31 ± 12.64 at three months, and 90.54 ± 10.71 at six months and remained at a low level 89.24 ± 8.92 at one year and 87.54 ±10.56 at two years. Mean VAS and AOFAS scores showed statistically significant pain reduction and functional improvements at successive follow-ups till 6month (p<.05); the improvement remained stable and did not change significantly until the last appointment at 2year follow-up (p > 0.05).

The outcomes of autologous PRP injection in recalcitrant plantar fasciitis are reliable, stable, and predictable in both long- and short-term follow-up. PRP injection is safer and not associated with serious complications as in the case of steroid injection.
Role of Vitamin D3 in fracture union in adults
Authors: Arora Arunabh , Kumar Singh Amrit
Published: August 2021

Fractures play an important role in morbidity and often premature mobility among the elderly population. Because inactivity as a result of a fracture is harmful both to bone healing and health, it appears early or rapid fracture healing would be highly recommendable for returning fracture patients to come back to normal as soon as possible with minimal side effects. The literature remains unclear regarding supplementation required for promoting bone healing in fracture cases. Hereby we evaluated the advantages and disadvantages of vitamin D3 supplementation in fracture cases along with the quantitative analysis of vitamin D3 at the time of fracture and after fracture union.

: A total of 200 patients were assessed clinically, biochemically (serum alkaline phosphatase, serum vitamin D3, and serum parathormone), and radiologically. All patients who satisfy inclusion criteria are followed up and vitamin D3 levels were measured up within 1 day of fracture and at the interval of 6 months after the orthopaedic intervention. The outcomes were monitored by the 5 points radiographic scoring system by Warden et al.

With the majority of patients falling under the vitamin insufficiency group i.e. 53% of all patients were found to be vitamin insufficient at the time of fracture. 33% of patients found to be vitamin D deficient while 14% found to be insufficient stage. No patient was found to be in a toxicity state. According to Warden’s scoring., 50% of patients were in grade 3, 15% in grade 4, 33% in grade 2, and only 2% in grade 1.

Regarding the prevalence of vitamin D deficiency or insufficiency in the general population, this study shows an alarming rate of vitamin D insufficient patients in a group of 200 patients, which indicates the need for attention towards vitamin D status not only for bone-related issues but for other issues related to vitamin D deficiency.

Emisiones de metano asociadas a la minería subterránea del carbón en el altiplano cundiboyacense (Colombia)
Authors: Mariño-Martínez Jorge Eliecer , Chanci-Bedoya Rubén Darío , Orjuela Garcia Angela Maria
Published: August 2021

A raíz del Acuerdo de Paris sobre el cambio climático, Colombia se comprometió a medir y reportar las emisiones de gases de efecto invernadero (GEI), entre estas, las emisiones fugitivas de la minería del carbón. El país ha venido reportando las emisiones a partir de tablas internacionales (nivel 1 del Panel Intergubernamental del Cambio Climático - IPCC), pero en la presente propuesta se sugiere hacerlo a partir de los estudios de exploración de nivel 2 del metano de lecho de carbón (coal bed methane, CBM) utilizando equipos de desorción con canisters. En el altiplano cundiboyacense se revisaron los contenidos a partir de tablas internacionales y de estudios de CBM y se encontró que a partir del rango del carbón de nivel 1 (61,62 Gg de metano) las emisiones excedían los contenidos encontrados en mediciones directas de nivel 2 (16,47 Gg de metano) en más de 300 %. También se encontró que los niveles de emisiones equivalentes en toneladas de CO2 eran de 1.540.500 y 411.750 toneladas, en Boyacá y Cundinamarca, respectivamente. Los resultados evidenciaron que dado que los contenidos de gas metano asociados al carbón en las cuencas colombianas no son tan altos como los de los principales países productores de carbón, las emisiones de la extracción de carbón en el país fueron menores que las calculadas con factores de emisión internacionales. Por lo tanto, mientras no se midan las emisiones directamente en la ventilación, se deben utilizar los estudios de exploración de CBM para reportar emisiones, ya que con base en las tablas internacionales podrían estarse reportando más emisiones de GEI asociadas a la minería del carbón de las que realmente se están generando.

We studied the response of catalytic sensors to hydrogen with various types of platinum-group catalysts (Pt, Pd, Ir, Rh, Pt+Pd) in the pre-explosive concentration range. Temperature dependences of sensory response are analysed. Dependences of the sensory response on the applied voltage demonstrates hysteresis behavior that can be explained by the partial transition of the oxides of the platinum group metals into the metallic phase at temperatures above 500 °С and the reverse oxidation of metals if temperature is below 400 °С. Catalytic sensors with Ir and Rh catalysts are more preferable for practical use in the detection of hydrogen.

Upregulation of FoxM1 protects against ischemia/reperfusion-induced myocardial injury
Authors: Zhang Gang , Yu Kun , Bao Zhi , Sun Xiaofeng , Zhang Dongying
Published: August 2021

Background. Ischemia/reperfusion (I/R) induced lethal tissue injury in myocardium. FoxM1 (Forkhead Box M1), expressed in proliferating cardiac progenitor cells, could regulate myocardial development. However, the role of FoxM1 in I/R-induced myocardial injury has not been reported yet. Methods. Rats were conducted with regional ischemia followed by reperfusion in myocardium through ligation of the left anterior descending coronary artery. Triphenyl-tetrazolium chloride staining was utilized to assess the infarct size. ELISA was performed to detect activities of creatine kinase-MB (CK-MB) and lactate dehydrogenase (LDH). Protein expression of FoxM1 in heart tissues and H9c2 were determined by western blot. H9c2 cells were used to establish a hypoxia/reoxygenation cell model, and the cell viability, proliferation and apoptosis were evaluated by MTT, EdU (5-ethynyl-2’-deoxyuridine) staining and TUNEL (terminal deoxynucleotidyl transferase dUTP nick end labeling) staining, respectively. Adenovirus (Ad)-mediated over-expression of FoxM1 was injected into the anterior wall of the left ventricle of rats to evaluate the role of FoxM1 on in vivo I/R-induced myocardial injury. Results. FoxM1 was reduced in heart tissues isolated from rats post myocardial I/R injury. Forced FoxM1 expression increased cell viability and proliferation of hypoxia/reoxygenation-induced H9c2, while repressed the cell apoptosis with increased Bcl-2 and decreased Bax and cleaved caspase-3. Injection of Ad-FoxM1 suppressed infarct size of the heart and decreased activities of CK-MB and LDH. Conclusion. FoxM1 attenuated I/R-induced myocardial injury, providing potential therapeutic target for the disease.

Published: August 2021

Background and Objectives: The oral cavity harbors numerous Streptococcus mutans strains which display remarkable genotypic and phenotypic diversity. This study evaluated the genotypic and phenotypic diversity of 209 S. mutans strains isolated from 336 patients with dental caries and compared with the universal reference strain, UA159.
Materials and Methods: Selective cultivation on mitis-salivaries-bacitracin agar and species-specific polymerase chain re- action (PCR) was carried out to isolate and identify the 209 S. mutans isolates from 336 patients with dental caries. Arbitrari- ly primed polymerase chain reaction (AP-PCR), PCR amplification of specific gene, acid production and biofilm formation capacity were performed to evaluate the genotypic and phenotypic variation. Student’s t-test and Chi-square test were used for analysis of variables and a probability (P) of <0.05 was considered as significant.
Results: Our study revealed a high degree of genotypic and phenotypic variability among the clinical strains. We observed significant differences in colony morphology, generation time, biofilm formation, and acid production while growing in cul- ture medium. All the clinical isolates were able to lower pH while growing in Todd-Hewitt broth. Consistent with phenotypic variations, we also observed genotypic variation by AP-PCR and gene specific PCR. AP-PCR analysis suggested that most of the patients with dental caries have distinct type of S. mutans strains. Genes related to various two component systems were highly conserved among the isolated strains, however, bacteriocin encoding genes such as nlmAB, nlmC were absent in nearly half of the clinical isolates.
Conclusion: Our results support that S. mutans clinical isolates have wide genotypic diversity and show variation in growth kinetics, acid production, acid tolerance and biofilm formation capacity and indicates the presence of diverse mechanism to initiate and establish the biofilm lifestyle which leads to tooth decay.

Published: August 2021

Background and Objectives: Neisseria meningitidis, Escherichia coli K , Streptococcus agalactiae, and Streptococcus pneumoniae cause 90% of bacterial meningitis. Almost all infected people die or have irreversible neurological complica- tions. Therefore, it is essential to have a diagnostic kit with the ability to quickly detect these fatal infections.
Materials and Methods: The project involved 212 patients from whom cerebrospinal fluid samples were obtained. After total genome extraction and performing multiplex quantitative polymerase chain reaction (qPCR), the presence or absence of each infectious factor was determined by comparing with standard strains.
Results: The specificity, sensitivity, positive predictive value, and negative predictive value calculated were 100%, 92.9%, 50%, and 100%, respectively. So, due to the high specificity and sensitivity of the designed primers, they can be used instead of bacterial culture that takes at least 24 to 48 hours.
Conclusion: The remarkable benefit of this method is associated with the speed (up to 3 hours) at which the procedure could be completed. It is also worth noting that this method can reduce the personnel unintentional errors which may occur in the laboratory. On the other hand, as this method simultaneously identifies four common factors that cause bacterial meningitis, it could be used as an auxiliary method diagnostic technique in laboratories particularly in cases of emergency medicine.

Published: August 2021

Background and Objectives: Human T-lymphotropic virus type-1 (HTLV-1) belongs to retrovirus family that causes the neurological disorder HTLV-1 adult T-cell leukemia/lymphoma (ATLL). Since 1980, seven subtypes of the virus have been recognized. HTLV-1 is prevalent and endemic in some regions, such as Africa, Japan, South America and Iran as the endemic regions of the HTLV-1 in the Middle East. To study HTLV-1 subtypes and routes of virus spread in Iran, phylogenetic and phylodynamic analyses were performed and for as much as no previous phylogenetic studies were conducted in Tehran, we do this survey. To this purpose, the Tax region of HTLV-1 was used.
Materials and Methods: In this study 100 samples were collected from blood donors in Tehran. All samples were screened for anti-HTLV-I antibodies by ELISA. Then, genomic DNA was extracted from all positive samples (10 people), and for confirmation of infection, ordinary PCR was performed for both the HBZ and LTR regions. Moreover, the Tax region was amplified and purified PCR products were sequenced and analyzed, and finally, a phylogenetic tree was constructed using Mega X software.
Results: Phylogenetic analysis confirmed that isolates from Iran, Japan, Brazil, and Africa are located within the extensive ‘‘transcontinental’’ subgroup A clade of HTLV-1 Cosmopolitan subtype a. The Japanese sequences are the closest to the Iranian sequences and have the most genetic similarity with them.
Conclusion: Through phylogenetic and phylodynamic analyses HTLV-1 strain in Tehran were characterized in Iran. The appearance of HTLV-1 in Iran was probably happened by the ancient Silk Road which linked China to Antioch.

Published: August 2021

Background and Objectives: Non-thermal atmospheric-pressure plasma or cold plasma is defined as an ionized gas. This study aimed to investigate the effect of cold plasma on Pseudomonas aeruginosa strains. Also, the expression level of the alp virulence gene before and after treatment with cold plasma was compared with the Housekeeping gene gyrA.
Materials and Methods: P. aeruginosa isolates recovered from hospitalized burn patients at Shahid Motahari Burns Hos- pital, Tehran, Iran. The Kirby Bauer disk diffusion method was used to determine the antimicrobial susceptibility test. Then, the antibacterial effect of atmospheric non-thermal plasma was evaluated on P. aeruginosa in as in vitro and in vivo studies at different times on Muller Hinton agar and in mouse model (treated by plasma every day/ 90 sec). The histopathological study was evaluated by Hematoxylin-Eosin staining. Data were analyzed using SPSS software by the Chi-square test and Pvalues less than 0.05 considered as statistically significant.
Results: Results indicated that non-thermal atmospheric plasma inhibited the growth of P. aeruginosa. The non-thermal helium plasma accelerates wound healing for 6 days. Results showed that cold plasma decreased virulence gene expression alp after treatment. Therefore, cold plasma can be suggested as a complementary therapeutic protocol to reduce bacterial infection and accelerate wound healing and reduce the expression of virulence genes of pathogens.
Conclusion: Cold plasma showed pathogen inhibitory properties of P. aeruginosa and virulence alkaline protease and wound healing properties in animal models, so this inexpensive and suitable method can be presented to the medical community to disinfect burn wounds and improve wound healing.

Parental Counseling and Its Effects on the Formation of the Child's Personality
Authors: Rosu Camelia Augusta
Published: August 2021

Raising children is a challenge, as children grow, change, go through a series of evolutionary phases with different tasks and goals, which the parent often does not know. The child starts from the stage where his primary need is care until he has to detach from his parents to explore the world. Parental counseling is of fundamental importance regarding the physical, cognitive and psychosocial development of the child in the first years of life. The socio-economic status and the cultural context influence the way parents raise and educate their children. Many of the parents living in poverty and social exclusion, concerned about the conditions in which they live do not realize their parental style and its influence on the development of children, do not problematize the parent-child relationship and the importance of the first years of life for the formation of the child's personality. The article illustrates how through different sessions of parental counseling 50 Romani families from different marginalized communities in Alba Iulia were supported, in their educational role and in activating resources and skills for raising children. Families who have been parental counselors have become aware of the importance of children's education, the need to go to school, the value of attachment in building the parent-child relationship, and the future relationships that the child will have in the future, etc. Parental counseling offered parents a path through which to deepen, clarify, improve their educational style and family communication.

Published: August 2021

This paper aims to explore the experiences of first, fifth, and seventh grade teachers (N = 23) in competence-oriented teaching from one elementary school included in the implementation of an experimental curriculum reform program in the Republic of Croatia. Based on the qualitative case study approach, the analysis of teacher evaluation protocols considered teachers’ opinions in the context of achieving learning outcomes with the use of teaching activities and methods. The paper also analyzes teachers’ opinions about the required changes in the planning and implementation of the teaching process as well as their professional development. For the learning success to increase, it is important for teachers to emphasize with their competences the organization of pupil-centered activities in achieving learning outcomes that change the approach to the planning of teaching. The focus of contemporary teaching should be on problem solving, active involvement of pupils in the teaching process while respecting the pupils’ interests, experiences, needs, motivations, prior knowledge, and expression of creative abilities. The teaching process focuses on constructivist teaching and the conceptual approach using collaborative methods and forms of work, technology in teaching, formative evaluation, and innovative approaches, whose intensity and complexity varies in different circumstances.
Exploring Saudi Students’ Perceptions of National Exams: A Washback Study
Authors: Alsagoafi Ahmad
Published: August 2021

Research on washback and impact of tests (either positive or negative) on teaching and learning in the language assessment field has proliferated in approximately the last three decades. This study aims to explore the positive washback of the General Aptitude Test (GAT) and Scholastic Achievement Admission Test (SAAT) based on the perceptions of secondary school students in Saudi Arabia since this topic is underresearched in the literature. While the existing research has provided insight into the validity and reliability of these tests, we have a limited understanding of how these tests can positively impact the performance of students. In this qualitative study, data were collected from 103 participants using a case study approach through the means of semistructured questionnaires and semistructured interviews. Data were analyzed inductively by employing a computer program called NVivo. The results of the study showed that the participants were positively influenced by the test. This impact was manifested in students’ low pressure test-taking experiences, their successful honing of soft skills needed for future university study instead of reliance merely on indoctrination or the memorization of information and the feasibility of enrollment in universities because the Secondary School Certificate (SSC) is no longer the sole indicator of academic performance. Students’ scores increased due to the method of testing, test preparation and test retaking, which played key roles in promoting score gains and thus accentuating a positive washback.

The Impact of Feedback on Students’ Autonomous ESP Learning Outcomes
Authors: Dmitrenko Natalia Yevheniivna , Budas Iuliia Oleksiivna
Published: August 2021

The present paper provides the results of the feedback influence on students’
autonomous ESP learning. It is aimed to study the impact of feedback on autonomous
learning outcomes of first-year students, who are studying a two-year university course
of “English for Specific Purposes (ESP)”, the significant part of which is dedicated to
self-regulated learning. The aim of the course is to improve the students’ proficiency
in professionally oriented English communication to the level of B2 according to the
Common European Framework of Reference for Languages (CEFR). The investigation has
proved the importance of teachers’ support in students’ autonomous ESP learning. The
outcomes of those students who received the feedback regularly signify that even being
self-sufficient, students strive for teachers’ or peer observation and feedback in the
educational process. In the article, the interdependence between the level of students’
autonomous ESP learning competence and students’ feedback literacy is presented. The
results of the study suggest that students’ autonomous ESP learning outcomes are
considerably influenced by supportive external written feedback if it is sought, and
their feedback literacy level is at least moderate or higher. A higher level of
students’ feedback literacy is observed among students with a more advanced level of
autonomous ESP learning competence and who demonstrate better academic achievements in
professionally oriented English communication. The coherence of the elaborated levels of
Ukrainian students’ feedback literacy and the ways of its enhancing can be significant
for educators in other countries.

Knowledge of the English language is very important not only for civil but also
for the military personnel because there are a lot of changes in defense relations all
over the world and English is the operational language. So, we should focus on high
quality training of specialists who are able to work not only under standard conditions,
but also to solve professional problems. According to the Ukrainian current legislation,
one of the professional competences of border guards is to speak in English while
accomplishing duties on the state border. So there is a necessity to analyze methods and
ways of organizing the educational process of this category. The article reflects the
key issues connected with the educational program of border guards; investigates
integral, general and professional competencies and program learning outcomes. The main
attention is paid to peculiarities of English for Specific Purposes and its aim to form
foreign professional communicative competence according to the NATO Standards at the 2nd
level. The hypothesis of our article is that the development of the national security
masters’ communicative language ability depends on use of up to day learning methods at
the English language lessons. The discipline ESP for border guards training includes
such themes: “Conceptual bases of politics and public administration in the sphere of
national security and defense of Ukraine”, “Border security of Ukraine”, “Border
Security of the USA and EU country-members” and “Conceptual bases of politics and public
administration in the sphere of national security and defense of the USA and EU
country-members”. The organization of the lesson “Land navigation: map reading” has been
discussed and its five-stage plan (introduction, input, practice, production, and
conclusion) has been investigated. The information obtained from this paper could be of
interest for English for Specific Purposes teaching material developers and foreign
language instructors.

Willingness to Forgive Oneself and Others as a Way of Personal Growth of University Students
Authors: Kravchuk Svetlana
Published: August 2021

The article is devoted to the problem the personal growth of students in educational environment. It is indicated that psychological consultation with students in the educational environment on interpersonal problems is a factor in their personal development. The relationship between willingness to forgiveness oneself and others and personal growth in university students is analyzed. The factors of personal personal growth in university students were investigated. The following hypotheses were formulated: 1) willingness to forgive oneself and others, trait forgivingness in university students are positively correlated with personal growth, personal self-efficacy; 2) willingness to forgive oneself and others, trait forgivingness, hardiness, sociability, psychological resilience are significant factors of personal growth in university students. The participants were 512 Ukrainian university students (260 women; 252 men). Scale of Deep Readiness for Forgiveness, Trait Forgivingness (dispositional) Scale, Overall Self-efficacy Scale, Scale of psychological well-being, Psychological Resilience Scale (PRS-11), Freiburg Personality Inventory, Hardiness Test, Mental Health Outcome Measures, Depression and Anxiety (BSI – 12) were applied. Pearson’s correlation coefficients to test the features of the relationship between willingness to forgiveness and personal growth, personal self-efficacy in university students were investigated. The multiple regression analysis for the factors of personal growth in university students was performed. The important factors of personal growth were identified by the study. High levels of willingness to forgiveness, trait forgivingness, sociability, personal self-efficacy, autonomy, psychological resilience, hardiness, self-acceptance increase personal growth university students. The presented findings should be taken into account by persons offering professional support for university students.

In the era of digitalization and informatization of the world community blended learning is becoming more and more prominent in improving professional training of students in various specialties as it enables to provide efficient learning, achieve learning goals and, what is more, to build their confidence. The aim of the research is to investigate the influence of blended learning incorporated into the professional training of students doing a BA degree in Teaching English as a Second Language on the increase of their general self-efficacy. To establish the relationship between the students’ general self-efficacy and blended learning we used a questionnaire. 133 students were selected to take part in a quantitative study which was conducted at three Ukrainian universities in 2019/2020 academic year. A non-random sampling technique basing on the fact that all 133 respondents studied the same disciplines was used to select the research sample. All the respondents were divided into experimental and control groups. The experimental group was represented by 65 undergraduate students and the control group was represented by 68 undergraduate students. The disciplines selected for training all the respondents in the experimental and control groups were “Contrastive Grammar of the English and Ukrainian languages”, “Practical Grammar of the English Language”, “The Practical Course of the English Language”. The experimental group was to be taught through incorporating blended learning courses on the selected disciplines using the Moodle platform and the control group was to be taught through providing a face-to-face instruction on the selected disciplines. To draw firm conclusions we used methods of mathematical statistics and computer data processing. Obtained results revealed a positive and significant relationship between the incorporation of blended learning into the professional training of students doing a BA degree in Teaching English as a Second language and the increase in their levels of general self-efficacy.

New social needs in education at the beginning of the XXI century are primarily associated with the peculiarities of the development of higher education, which places high demands on the personality and professional activity of a physical education teacher, in difficult conditions, when the world is at a difficult stage of development, indicated by the search for an optimal socio-economic format of coexistence in the global space. The new concept of education requires the improvement of the pedagogical activity of future teachers and their achievement of the development of a high level of personal and professional potential, taking into account the socio-economic environment in which the national concepts of preparing young people for life in a changing and unpredictable world order compete, fighting for their right to dominance. The main purpose of the article is to form an algorithm for developing an individual educational trajectory, which is decisive in the formation of personal and professional potential of the future physical education teacher. To simplify and systematize this individual trajectory as much as possible, we used the IDEF0 functional modelling methodology, which allows us to visually see the algorithm of functioning of the studied process and the main elements that will be needed.

Published: August 2021

Designing the mechanisms of modern machines is a complex process, where the stage of structural analysis is a priority. When there are a plenty of redundant links in mechanisms their load capacity and efficiency are reduced, increasing the requirements for the accuracy of manufacturing and assembly. It is desirable that mechanisms not requiring high torsional stiffness have no excessive connections; they should be self-aligning. With the advent of new multi-link spatial mechanisms, the task of creating mechanisms without redundant connections becomes more complicated. The structural analysis of the rhombic mechanism of the Stirling engine with a advanced connecting rod of the working group, carried out by the graph method.

Authors: Belkin A.E. , Duradzhi V.Yu.
Published: August 2021

The article considers solving the problem of large axisymmetric deformations of elastomeric torus shells of revolution, loaded with jointly acting torques, axial and centrifugal forces. The task is posed due to the calculation of rubber elements of couplings. The calculations are performed according to the momentless shell theory by solving a nonlinear one-dimensional boundary value problem using the shooting method, as well as in a three-dimensional formulation using the finite element method. The calculation results are presented both for convex and concave torus shells. The load characteristics are compared for free and constrained torsion. The dependence of axial reactions in supports on torque and centrifugal forces has been investigated.
