The principle of adversarial parties in Russian and Armenian law (comparative analysis)
Authors: Ilyuhina Vera
Published: September 2021

The article provides a comparative analysis of the adversarial principle of the parties in the procedural legislation of the Russian Federation and the Republic of Armenia. The author comes to the conclusion that this principle in Russia and Armenia is normatively fixed at different levels and occupies a different place in the system of principles of national law. From the standpoint of dividing the principles of law into sectoral, inter-sectoral and general legal in the Russian Federation, the adversarial principle is inter-sectoral, and in the Republic of Armenia it is a principle of criminal procedural law. From the position of division the principles of law according to the source of consolidation in Russia, the adversarial principle is one of the constitutional principles duplicated in sectoral legislation, and in Armenia this principle is simply sectoral.
Technical and legal culture as the basic basis for the effective functioning of the system of power and non-power principles of modern Russian law
Authors: Baranova Marina , Kuptsova Olga
Published: September 2021

The article is devoted to the analysis of the concept and specifics of the emerging technical and legal culture in the conditions of a new technological way of life characteristic of post-industrial society. The legal culture of modern Russian society is characterized by a change in its essential basis, which is based on the revival of a number of traditions, the formation of innovations in line with the active processes of digitalization of society, this gives reason to believe that there is a need to distinguish and distinguish from related legal phenomena an independent legal category – technical and legal culture. The prospective relevance of the research is based, first of all, on the challenges of legal practice, which determine a set of clear requirements for the professional activity and training of a lawyer. Recognizing the validity of the conclusion about the inseparable connection of legal and non-legal, power and non-power regulators and instruments of influence, it should be assumed that this has a significant impact on the specifics of legal technology, legal culture, technical and legal culture in relation to various types of legal practice. The analysis of the possibility of a specific division of technical and legal culture is particularly relevant, its main features are revealed in accordance with these typological groups. Based on the dominant features and manifestations of technical and legal culture, analyzed in the context of the search for the basis for the effective functioning of the system of power and non-power principles of modern Russian law, the article offers a primary, “working” definition of the concept of technical and legal culture, which as an independent phenomenon is currently in the formation stage. Its active development will contribute not only to the improvement of legal culture in general, but also to the development of various spheres of modern society.

EXPLORING THE IMPACT OF ECONOMIC GROWTH AND INFLATION RATE ON UNEMPLOYMENT IN INDIA
Authors: Sunita Kumari
Published: September 2021

In India, it has been observed that after the Economic Reforms of 1991, the participation of labor force has increased marginally but the rate of unemployment has remained unchanged which still remains a matter of concern. On the other hand, India has faced the issue of persistent rise in prices which is another major problem. As both these parameters are vital measures of economic growth, this paper attempts to find the correlation between both these variables in the Indian context from the year 1991 to 2019. A. W. Phillips in his theory states that inflation and unemployment have a stable and inverse relationship. The major claim of the theory is that with economic growth comes inflation, which in turn should lead to more jobs and less unemployment. On the basis of Phillips Curve this paper attempts to analyze the effect of economic growth and Inflation on unemployment in India during the time period of 1991 to 2020. The observational findings revealed a negligible association between unemployment, inflation and economic growth in India.

Authors: Sarsam Saad Issa
Published: September 2021

Modifying asphalt binder with additives can enhance the overall physical properties of asphalt concrete. In the present investigation, an attempt has been made to use 2 % of silica fumes and 4 % of fly ash class F for modification of asphalt binder in wet process. Asphalt concrete wearing course slab samples have been prepared under roller compaction. The beam specimens of 400 mm length and 50 mm height and 63 mm width were extracted from the slab samples. The beam specimens were subjected to the four-point repeated flexural bending beam test. The flexural stiffness was calculated under three constant micro strain levels of (250, 400, and 750). The fatigue life was monitored in terms the number of load repetitions to reach the required reduction in stiffness of 50 %. It was concluded that the flexural stiffness increases by (11, and 15) %, (17.7, and 63.6) %, (57.2, and 65) % when 2% of silica fumes or 4 % of fly ash are implemented and the specimen’s practices 750, 400, and 250 micro strain levels respectively. However, the fatigue life increases by (40, and 72.8) %, (115, and 220.6) %, (46, and 94.6) % when 2% of silica fumes or 4 % of fly ash are implemented and the specimen’s practices 750, 400, and 250 micro strain levels respectively. It is recommended to use modified binder with silica fumes and fly ash in asphalt concrete to enhance the fatigue life and stiffness.
Visualización del acoso en tendederos universitarios; una construcción de paisajes lingüísticos
Authors: Chan Pech Cándido
Published: September 2021

Los espacios universitarios son escenarios donde la violencia de género y acoso sexual vive en la cotidianidad, pocas veces han sido exhibidas por la dominación del poder del sistema patriarcal además de la amenaza de coacción en consecuencia. Sin embargo, la necesidad colectiva de visualizarla en los llamados tendederos, donde las alumnas escriben en hojas de papel su denuncia de manera anónima; son prácticas que están visualizando y exhibiendo las representaciones del acoso sexual: miradas y proposiciones. Desde un tratamiento semiótico-lingüístico se atendió la invitación para dilucidar el sentido de tal práctica como una puesta colectiva de visualizar lo inaparente de la violencia en la universidad. La intención principal de este artículo es plantear el tendedero como la construcción de un paisaje lingüístico y como práctica de visualización del acoso sexual como referente inmediato de las conceptualizaciones en los espacios de la universidad.

Unsteady Transition From a Mach to a Regular Shockwave Intersection
Authors: Karabelas S. J. , Markatos N.C.
Published: September 2021

The purpose of this research work is to perform accurate numerical computations of supersonic flow in a converging nozzle and specifically to study Mach-disks. The latter process has been widely studied over the last years. In the present study numerical simulations are performed for transient supersonic flow, tracing the transition from a Mach reflection to a regular one. This has been done by enforcing the walls of a converging nozzle to come closer together, changing the deflection angle with time. Viscosity was taken into account and the full Navier- Stokes have been solved. The results obtained clearly show the gradual extinction of the Mach disk and the eventual wave intersection to a single point

Authors:   Kyrgyz-Turkish Manas University, Mendesheva Meerim
Published: September 2021

The purpose of this article is to describe the meaning of the adjective rich and its systemic connections in the linguocultural aspect. Tasks: 1) determine the lexicosemantic variants of the adjective rich; 2) identify its synonyms and antonyms; 3) compare the semes of the adjective rich presented in different dictionaries. The relevance of this paper lies in the fact that the English linguistic worldview includes a certain area associated with linguocultural ideas about wealth that is represented by the adjective rich and its synonyms and antonyms. The scientific novelty of the article lies in the fact that for the first time the semes of the adjective rich are considered in terms of linguistic worldview and the theory of mentality. The research material was selected from modern authoritative English dictionaries. The main methods used here are the method of component analysis of vocabulary definitions, descriptive method using interpretation and generalization techniques, comparative method, and elements of the linguocultural method. The analysis showed that the adjective rich in the English language has 34 semes, which can be combined into 8 thematic groups: 1) person: ‘someone/person/people’, ‘endowed’, ‘have’, ‘possessions’, ‘contain’; ‘entertainment’, ‘(highly) amusing’, ‘(highly) developed’; 2) material wealth: ‘(a lot of) money/material wealth/property’, ‘(financially) profitable’, ‘remunerative’, ‘valuable/high value’; 3) abundance: ‘lush/abounding/abundant’, ‘a high standard of living’, ‘supplied’; 4) perception: ‘colour’, smell/fragrance’, ‘sound/tone’, ‘taste’; 5) something material: ‘(natural) substance’, ‘food (with fat/oil/eggs/sugar)’, ‘plant/nutrients’; 6) resources: ‘combustion’, ‘source’; 7) evaluation: ‘attractive/magnificently impressive/pleasant’, ‘beautiful’, ‘good’, ‘(highly) productive’, ‘(highly) varied’, ‘useful’; 8) quality: ‘complex’, ‘pure/nearly pure’, ‘percentage’, ‘quality’. In addition, 26 synonyms and 4 antonyms of the adjective rich were identified.
The Category of Interpretability of the Literary Text and the Problem of Multi-Layered Interpretation of Prose (Based on Ivan Bunin’s Short Stories “The Book” and “The Chapel”)
Authors:   The Herzen State Pedagogical University of Russia, Sergeeva Elena
Published: September 2021

Determining the main categories of the literary text is a matter of debate among researchers today. According to the author of this paper, the most significant categories are the following: fiction (virtual information content), egocentricity (image of the author), aesthetics, linguocentricity, and interpretability. The article focuses on the category of interpretability, which is associated with the ability to perceive a text from different perspectives and at different depth levels. Interpretability is the ability of a text to generate ambiguous information that can be read and formulated in different ways and be either perceived or not perceived by the addressee. Description of the interpretability category is exemplified by Bunin’s short stories “The Book” and “The Chapel”. “The Book” allows the reader to perceive several semantic layers, gradually complicating the content of the text and its understanding. This story clearly demonstrates that interpretability of a literary text can reach absolute ambivalence of the perception of this text: life is more important than fictional books, but life itself, probably, exists for the art in order to be embodied in a word. The thesis about multidimensionality and interpretability of the literary text is confirmed when we turn to another short story, “The Chapel”. The analysis of the texts performed demonstrates that a work of art can be perceived ambiguously, its content is interpreted on the basis of acquired additional meanings of its lexical units, various shades of meaning of its syntactic constructions and the possibility to perceive sequential fragments of the text differently, as well as depending on the personality of the addressee. A conclusion is made that the category of interpretability is, indeed, characteristic of the literary text, fully in line with the genre’s specifics, i.e. the aesthetic transformation of meanings in order to create virtual reality with the help of language.

Orthodontic implants, called mini-implants or temporary anchorage devices, have been designed to meet the needs of orthodontic biomechanics. Having the goal of providing resistance to unwanted tooth movements, anchorage is chosen according to the main factors that influence the quality of orthodontic care. Of these, local factors such as bone quality, space, thickness of the gum, etc. should be correlated with those watching the mini-implant design, geometric and dimensional factors that are taken into account for the stability of the mini-implant. This paper summarizes some of the results of the research aimed to analyze the main factors of stability of mini-implants used for orthodontic anchorage and how to measure it using the mini-implants (design shape and dimensions) and a special equipment for testing the tensile strenghth.

Introduction. Miniimplant overdenture is a treatment option with numerous subjective and objective benefits for the edentulous patient. Aim. This study aims to analyse the changes and benefi ts in terms of mandibular movements, that occur in the process of transforming conventional dentures into miniimplant supported overdentures, through kinesiograph exam with the JMA system (Jaw Motion Analyser, Zebris, Isny im Allgäu, Germany). Material and methods. For the study we used ultrasonic kinesiography with the JMA system (Jaw Movement Analysis, Zebris, Isny im Allgäu, Germany), connected to a computer, which enables recording, documenting and processing of the functional data from the edentulous patients. A series of kinesiographic exams were undertaken, using the JMA system Zebris), with conventional dentures with and without denture adhesive, after insertion of mini dental implants (mini SKY, Bredent, Senden, Germany), with the denture soft lined and after O-rings were applied. Conclusion. Kinesiographic recordings show positive changes of the measured data and confirm the benefits of the treatment, subjectively reported by patients.

Objectives. The comparative evaluation of the role and information contribution brought by panoramic radiography (X-ray) and CT to the preoperative assessment of third molars, found in different stages of eruption. This assessment is useful both for certifying the diagnosis and for establishing the proper surgical strategy adapted to specific clinical cases, in order to avoid undesirable surgical incidents and postoperative complications. Patients and method. This is a retrospective study in which 23 patients were enrolled, on whom 79 third molars were identified. All these molars had, for various (historical and clinical) reasons, removal indications. Sex distribution of the patients was: 6 (26%) men and 17 (74%) women. After a detailed clinical examination, a digital panoramic radiography was performed on all patients, which provided additional useful information. This imaging investigation allowed a sorting out of the cases in which an additional preoperative imaging investigation, such as CT, was required. CT information was compared with that obtained from panoramic radiography (X-ray) and surgery intervention data. Results. In this study imaging investigation was performed on 79 third molars: 41 (51.9%) on upper third molars and 38 (48.1%) on lower molars. As concerning the stage of impaction, 22 (27.84%) were impacted and the same percent was found for those partially impacted. In 22.5 (28.48%) cases root dilacerations were identified. Special attention has been granted to the anatomical relationship of third molar roots with nearby structures: maxillary sinuses and the mandibular canal. So, from the upper third molars, 13 (31.7%) were in the sinus and so were those which were in close relationship with the sinus. Conclusion. Panoramic radiography (X-ray) provides orientative and often insufficient information about root morphology and anatomical relationships of third molars. In the clinical cases which required a comprehensive imaging assessment, CT data were crucial for adapting surgical procedures to specific clinical situations, minimizing surgical incidents and postoperative complications. Discerning recourse to 3D imaging ensures net benefits for patients as well as for dental practitioners.

Background. The paper describes the case of a 62 years non-smoking male patient who was referred to the Department of Periodontology, “Carol Davila” University of Medicine and Pharmacy, complaining of gingival overgrowth. The patient’s medical history revealed that he suffers from autosomal dominant polycystic kidney disease chronic renal failure and hypertension; the patient was under treatment with amlodipine, a calcium channel blocker for 18 months. Case presentation. The patient underwent cause-related periodontal therapy and flap surgery in areas where only partial resolution of the gingival overgrowth was obtained after completion of initial phase therapy; amlodipine was not substituted because of medical reasons. Results. We obtained complete resolution of the gingival enlargement, even without any change in the causative drug regimen; the patient was placed in a maintenance program, with regular appointments at 3 months; he successfully managed to maintain periodontal and oral health. Conclusions. If possible, all patients who are about to receive calcium channel blockers, should have a detailed periodontal assessment performed and if any periodontal disease discovered, treated properly. In case of established gingival overgrowth, non-surgical and/or surgical periodontal therapy could induce partial or complete remission of enlargement. Change of medication is also an option.

Apical inflammatory root resorptions are frequently the result of long lasting chronical inflammation. Untreated, these situations can lead to loss of hard tissue and even the loss of the tooth. The management of these lesions consists of multi-visit canal treatment, with calcium-hydroxide as interappointment dressing and application of MTA. Single-visit treatment may be also an option. Our clinical cases show the importance of correct diagnosis of the apical inflammatory progressive root resorptions and the evaluation of the outcome of the endodontic treatment due to the use of cone-beam computing tomography (CBCT). The treatments proved to be successful. Although some of the root canal filling seem to be incomplete on radiographs, because of the oblique defect and the roots remained short, the functionality of the teeth could be preserved. Precise information influences the diagnosis and the treatment planning decision.

Caries diagnosis should be done in the early stages in order to preserve long-term hard dental structures. In addition to that, the cavity lesions treatment should use adhesive materials for crown obturation which allow strictly carious lesion removal and do not require the creation of retention forms, involving an additional sacrifice of dental tissues, thus jeopardizing the tooth resistance. The study presents the case of a 9 years old, male patient who had multiple cavities in the mixed dentition. The designed treatment plan aimed, firstly, at assessing the degree of damage, trough cavities, of the four 6-year molars existing on the arcades and the choice of techniques and materials for coronal restoration following ART concept (Atraumatic Restorative Treatement). Cavities diagnosis was made by combining conventional methods (visual inspection, inspection and palpation by probe, retro alveolar radiography and OPG) and modern methods (laser fluorescence DIAGNOdent Pen 2190). The prime molars 36, 46 treatment consisted in the creation of some VI class cavities, than plugged with glassionomer cement (Fuji IX) due to increased and prolonged release of fluoride, while the 16, 26 molars treatment was achieved by incipient lesions remineralization by topical application of a fluoride varnish containing 5% sodium fluoride (Profluorid varnish, Voco GmbH).

Definitions. The biomechanical risk factors individually analyse the most relevant bio-mechanical aspects of implant-borne rehabilitations. They are expressed by numbers and can be used to foresee the outcome of a case yet to be treated or to analyse the achieved result of an already completed case. The biomechanical score is the outcome of a calculation method intended to assess the long-term result of an implant-borne rehabilitation. SRIAC (Screw-Retained Integrated Abutment Crown) is a single-tooth, implant-borne rehabilitation manufactured of indirect composite which is chemicaly bonded to its abutment. Both are screwed into the implant as a one-piece unit. Aim. To present a simple method which enables safe removal, e.g. safe unscrewing of cemented implant-borne single-tooth crowns. Materials and methods. For the purpose of this study we have treated between January 2014 and February 2015 forteen single-tooth implant-born cemented crown cases which can be removed, e.g. unscrewed anytime due to their occlusal screw opening. Further on, in order to check if the achieved retrievability has improved their outcome, we have calculated for each crown the corresponding Renouard-Rangert biomechanical score. Results. For all the 14 cases the biomechanical score has improved with at least 0.5 points. Discussion. The presented cases come up with a simple solution which enables the crown-abutment one-piece to be unscrewed/screwed en-bloc. Conclusions. 1. This method can be applied using both straight or angled abutments for cemented superstructures. 2. This method enables manufacturing implant-borne screw-retained single-tooth crowns even if the abutment for screw-retained superstructures does not feature an anti-rotational locking system. 3. This method cannot be applied in the front area if the abutment screw extension is protruding through the buccal side of the crown. 4. Definitive conclusions will be reached based on statistic data including at least 100 cases followed-up for at least 5 years.

Marriage rates of the population in Bulgaria: features and trends of change
Authors: Traykov Toni , Tsvetkov Kaloyan
Published: September 2021

The paper studies the past and contemporary marriage rates in Bulgaria. The analysis starts with the marriage patterns after the Liberation, when high marriage rates were observed, especially after the war periods. During socialism, the family was perceived as the main functioning cell of society and the marriage rates continued to be relatively high. In the 1990s and the beginning of the new century, a change in the marital behavior was observed – a significant postponement of entry into marriage and motherhood led to a family model that had not been common in the past. The authors also conclude that there are different stages in the marriage patterns in Bulgaria – both historically and spatially. The different factors affecting these processes are also studied and discussed in the paper.

Introduction: The aim of the study was to compare the neuroprotective and cerebrovascular effects of bioactive, endogenous lipid – N-arachidonoyl-GABA (AA-GABA) and GABA conjugate with prostaglandin E2 (PGE2-GABA) by evaluation of a morphological state of rat brain tissue and lipofuscin levels under the condition of permanent focal brain ischemia, as well as cerebral circulation under the condition of global transient ischemia.

Materials and methods: The study has been implemented using the models of the left middle cerebral artery occlusion (MCAO) and global transient ischemia of the brain. A morphological examination of the brain tissue, a registration of local blood flow by laser flowmeter, and quantitative measurement of lipofuscin by fluorescence spectroscopy were used.

Results and discussion: AA-GABA and the putative COX-2 metabolite PGE2-GABA showed significant neuroprotective and cerebrovascular effects in rat models of global and focal cerebral ischemia. In the MCAOmodel, AA-GABA and PGE2-GABA at a dose of 2 mg/kg/day administered i.p. for 6 or 12 days led to: 1) significant restoration of neurons and glial cells with intracellular regeneration of cytoplasmic and nuclear structures, 2) decrease in brain tissue edema; 3) attenuated thrombosis and stasis, and 4) absence of large necrotic foci in rat brain tissue. AA-GABA and PGE2-GABA at the same dose prevented excessive accumulation of lipofuscin in both brain hemispheres in rats with MCAO. All the studied compounds increase cerebral blood circulation in rats subjected to global transient ischemia. However, the cerebrovascular effect of PGE2-GABA was superior to the activity of AA-GABA and all other tested compounds. AA-GABA and PGE2-GABA, unlike PGE2 and nimodipine, increase the cerebral blood flow in rats with global transient brain ischemia and have no influence on the intact animals. Apparently, the GABAergic vascular system of the brain is involved in the mechanisms of the neuroprotective action of AA-GABA and PGE2-GABA.

Conclusion: For the first time, we demonstrated the ability of AA-GABAand its putative metabolite COX-2 PGE2-GABA to improve cerebral circulation, attenuate structural damage and lipofuscin accumulation during cerebral ischemia. The natural origin of AA-GABA, which possesses neuroprotective and cerebrovascular activity, as well as anti-aggregatory activity, allows considering AA-GABA as one of the endogenous protective factors in ischemic brain lesions.
Passado e educação: conceito epistemológico e professores de história
Authors: Gonçalves Rita de Cássia
Published: September 2021

O texto discute como o conceito epistemológico de passado se relaciona com a ciência histórica e as ideais de História de professores, que são antes de tudo historiadores, e como está sendo apresentada, discutida e ensinada na educação brasileira no século XXI. Apresenta seis categorias que mostram como o professor de história estabelece relações entre presente, passado e novamente presente, a partir da epistemologia da ciência de referência: passado estático, para criar empatia, enquanto memória e memorização, para orientação e histórico, e exemplifica com ideias apresentadas pelos professores. Se embasa teoricamente a partir das obras de Jörn Rüsen, Michael Oakeshott, Reinhart Koselleck, Peter Lee, David Lowenthal, e Peter Seixas. Tece considerações sobre como os professores entendem o passado e a epistemologia da ciência de referência na construção da relação o historiador inserido na sociedade da atualidade.

Published: September 2021

Acute coronary syndromes can develop with an unusual and challenging presentation. Kounis syndrome is a mostly overlooked Acute Coronary Syndrome (ACS) in the setting of anaphylactic or anaphylactoid reactions in response to an allergic insult that can lead to severe complications including cardiac arrest. A 52-yearold- man presented to the emergency department of our hospital because of acute transient loss of consciousness that developed some minutes after almonds ingestion. The complex diagnostic workup led to the diagnosis of vasospastic Kounis syndrome, an infrequent type of acute coronary syndrome, mostly overlooked, with challenging diagnostic and therapeutic features. Peculiarities on clinical presentation, the approach adopted by the emergency physician and the consultant cardiologist to achieve the correct diagnosis and our proposed management with a brief revision of the literature will be reported. Unusual clinical presentations of acute coronary syndromes represent part of the pitfalls that an emergency physician can face during the everyday practice. Prompt identification of these conditions is always struggling but of crucial importance to improve patient prognosis with a correct diagnostic work-up and therapeutic management.

People who emigrated from Turkey to European countries for work are called expatriate. It was aimed to analyze demographic characteristics of expatriate patients who presented to the emergency department, to compare satisfaction levels of emergency departments between their country of residence and Turkey, and to identify the factors that affect patient satisfaction. This descriptive study was conducted with questionnaires filled by face-to-face interviews in 150 expatriate patients who were living abroad, came to Turkey for vacation/annual permit and applied to the emergency department with any complaint. We found a statistically significant difference when we evaluated expatriate patients’ monthly average number of emergency department applies and their views on priority to apply to emergency departments for health problems, the cleanliness of emergency departments, attitude of doctors, security and receptionist/nursing staff towards patients in Turkey and in their country of residence. It has been found that expatriates prefer the emergency department more in our country and they are more satisfied in their country of residence in terms of the cleanliness of emergency department, attitude of doctors, security and receptionist/ nursing staff.

We describe the case of a 68-year-old man with a known history of hypertension and diabetes mellitus presented to our Emergency Department, complaining of hematuria and vomiting in the last 12 hours, stypsis and urinary incontinence in the last week, and worsening hyporexia in the last 6 months. Bedside ultrasound documented a slight right pleural effusion with B lines in the middle and basal right field, gastrectasis, dilated fluid-filled bowel loops, potential signs of gas in the upper right quadrant, grade 3 bilateral hydronephrosis, and bladder globe. Abdominal CT scan confirmed the bilateral hydroureteronephrosis and showed the right kidney with Emphysematous Pyelonephritis (EPN) with extension into the perinephric and muscular planes for 24 cm, and initial EPN in the left kidney. A RT-PCR nasopharyngeal swab for SARS CoV-2 was negative. A diagnosis of ileum paretic, acute renal failure and urosepsis due to EPN was made.

In this study, we aimed to investigate the role of miR-877-5p in the malignant phenotypes of prostate cancer (PCa) cells and its underlying mechanism. RT-qPCR analysis was performed to examine the expression of miR-877-5p and sperm-specific antigen 2 (SSFA2) in PCa tissues and cells. Cell counting kit-8 (CCK-8) assay, 5-ethynyl-20-deoxyuridine (EdU) assay, flow cytometry, wound-healing assay, and Transwell invasion assay were performed to determine the functional roles of miR-877-5p in PCa cells. The association of miR-877-5p with SSFA2 was determined by luciferase reporter and RNA pull-down assays. In this study, we found that the expression level of miR-877-5p was decreased in PCa tissues and cells. Functionally, overexpression of miR-877-5p exerted tumor suppressor properties in PCa cells. Mechanistically, SSFA2 was identified as a target gene of miR-877-5p, while overexpression of SSFA2 could abrogate the anti-tumor effects of miR-877-5p in PCa cells. These findings demonstrated that miR-877-5p/SSFA2 axis functioned as a potential target for PCa treatment.
