Influence of androgen deficiency on the endometrium structure in women of reproductive age
Authors: Demyanenko L. V. , Semenyuk L. M. , Yuzvenko T. Yu. 
Published: December 2021

Aim — to identify the relationship between androgen deficiency and the development of endometrial hypoplasia in women of reproductive age, to develop an algorithm for the diagnosis and treatment of this category of women.
Materials and methods. Examination of patients with androgen deficiency revealed 48 patients with endometrial hypoplasia based on the ultrasound markers. After examination for CD138 and detection of chronic endometritis during the study, 9 patients were excluded. At the second stage, an immunohistochemical examination was performed for the expression of receptors for estrogen, progesterone and androgens. According to the results, the patients were divided into 2 groups: the first group (24 patients) with a high level of expression of androgen receptors and the second group (15 patients) with a low level of expression of androgen receptors. Theexpressionof receptors to estrogens and progesterone was on medium level and comparative in both groups. Both groups of patients underwent hormonal therapy for 3 months: estradiol valerate 1 g per day in a continuous mode and 200 mg of micronized progesterone from the sixteenth to twenty-fifth days of the menstrual cycle. Additionally, patients of the first group received dehydro­epian­drosterone(DHEA)in a dose of 25 mg per day continuously in the form sublingual spray.
Results. According to the data of ultrasound examination in the first group of patients, the endometrium corresponded to normal parameters both during treatment and 1 and 3 months after stopping treatment. At the same time, in the second group of patients, there was an improvement in the thickness (more than 7 mm) and structure of the endometrium during treatment and the absence of these effects after the termination of hormonal therapy. Considering the recommendations of the Association of Endocrinologists on the superiority of non-tablet forms of androgen preparations in the treatment of androgen deficiency and having a positive and long-term effect when taking sublingual DHEA, it is possible to recommend adding the above form of DHEA to systemic therapy of endometrial hypoplasia against the background of androgen deficiency.
Conclusions. Women with androgen deficiency are more likely to have concomitant endometrial hypoplasia. Immunohistochemical examination of the endometrium of women of reproductive age with androgen deficiency in 24 patients (61.5 %) revealed a high level of expression of androgen receptors. The effectiveness of therapy for endometrial hypoplasia in women with androgen deficiency with addition of androgens to the standard regimens is more effective and has a long-lasting effect. The combination of estrogen-gestagenic therapy and androgens has a positive effect on the gestational potential of the endometrium in women of reproductive age with androgen deficiency.

Published: December 2021

Aim — to improve the results of treatment of diabetic anklearthropathies by using the final method of fixation by semi-rigid systems after arthrodesis and the use of extrafocal ring fixators (RF).
Materials and methods. The authors presented own experience of treatment of 12 patients with diabeticankle osteoarthropathy. After arthrodesis and fixation with RF, the alternating osteosynthesis was performed with Scotchcast/Softcast bandages.
The use of extrafocal RF of the needle-rod type in the first stage with low trauma wasadvantageous, however the time of fixation before the appearance of the fusion between the tibia and talus was significant, which led to a decrease in the rigidity of the fixation of the bone-needle system and development of inflammation at the exit of the spokes. This required the transition to other means of fixation, which would provide the possibility of functional use of the limb. The authors used Scotchcast/Softcast functional bandages, applied circularly, with stiffeners on the lateral surfaces, which allowed to carry out the supporting function of the limb.
Interventions (arthrodesis of the ankle joint) were performed under multimodal analgesia. Vascular disorders required hematopoietic therapy (use of a tourniquet and administration of tranexamic acid solution) and bemiparin administrationfor microthrombosisprevention. Treatment of diabetic neuropathy and metabolic disorders was carried out by prescribing vitamin B and C, drugs Ca and vitamin D3, antioxidants.
Results. The dynamics of the most examined indicators of the coagulation — anticoagulation system did not differ significantly (activated partial thromboplastic time, prothrombin time, international normalized ratio, platelet quantity). There was a tendency to shift the indicators to the recommended safe zone and even a significant decrease in the level of soluble fibrin monomer complexes (R2= 0.9494).
Conclusions. The use of Scotchcast/Softcast immobilizing bandages in patients with diabetic arthropathy was safe after arthrodesis and RF fixation.This strategy allowed to restore limb capacity in the early stages of treatment, which improved the social adaptation of patients.

Verbal representation of monster’s image in works for children of modern Ukrainian authors
Authors: Diachenko Nataliia , Kydysiuk Olesia 
Published: December 2021

The article investigates the peculiarities of the linguistic representation of monster image in modern Ukrainian children’s literature. The literary discourse of fear and monster image is presented. From the communicative-pragmatic point of view, the traditional, usual images of monster, in particular Babay and Chupacabra, are compared with their counterparts from the works of such popular Ukrainian writers. New images of the monster, the appearance of which was caused by the COVID-19 pandemic, are characterized.
The purpose of the article is to investigate the peculiarities of the linguistic representation of the image of monster in modern Ukrainian children’s literature.
The following research methods were used: linguistic observation and description of language phenomena; method of decoding an artistic text, analysis, synthesis, induction, deduction, as well as the method of continuous sampling.
It is established that in the works for children of modern Ukrainian authors the image of a fearless, good monster is gaining popularity, which testifies to the tendency to improve traditional negative images. To create «updated» images of monsters, writers use a range of language tools and stylistic devices. The individual author’s onyms for monster and occasional sign tokens are particularly expressive, which appear during the creation of these images. It is observed that the image of monster in children’s works implements a number of pragmatic functions: cognitive (acquisition and assimilation of knowledge about the world (about the world of things; about the world of human relations); developmental (enrichment of the child’s vocabulary, formation of reading skills, development of imagination, critical / creative thinking, cognitive interest, etc.); educational (formation of basic moral principles, learning patterns of behavior, etc.); entertainment (enjoyment of artistic communication). The study of the usual and occasional in the linguistic representation of fear and monster in the works for children of modern Ukrainian writers complemented the knowledge about the connection of the writer’s worldview with the works’ language and with the national linguistic picture of the world.
Negative constructions in theory and practice: Ukrainian-Belarusian parallels
Authors: Zanevych Olha , Hnatyuk Myroslava 
Published: December 2021

In the article the material of monumental texts of the Ukrainian language of the 16th – the first half of the 17th century (business documents, artistic, polemical, chronicle, scientific and confessional literature) and the studied monuments of the Old Belarusian language are studied the diachronic aspect of the use of case forms (generic or accusative) in negative verb constructions; their functioning in modern Ukrainian and Belarusian languages is analyzed.
It has been revealed that in the monuments of the Ukrainian language of the specified period the accusative case in denial is inferior to the generic one. The use of certain syntactic models (parallel use of genitive and accusative forms in the pre- and postposition) was determined by the general style and place of writing the monuments. In studies of monuments of the Old Belarusian language in this position the genitive was fixed, and sometimes in negative constructions the accusative and the genitive were allowed at the same time.
In the linguistics of the 20th – early 21st century philologists have repeatedly drawn attention to the peculiarities of the use of genitive and accusative cases in negative constructions both on the All-Slavic background and on the material of individual languages.
Synchronously, it has been revealed that in the modern Ukrainian language the literary norm in negative constructions is the use of the genitive case instead of the accusative. However, there is no noticeable tendency to replace the accusative and the genitive in verbs with a negative participle not, as there are many cases of using the possessive case in literature and in everyday speech. On the other hand, there is no unanimity in the grammars of the modern Belarusian language on this issue: some scholars believe that both generic and possessive cases are possible in negative constructions, while others believe that only generic is possible. However, from a sample of analyzed works of Belarusian writers of the twentieth century, artistic and journalistic posts, as well as conversational style records, it can be argued that there are only a few cases of use of the accusative case, in particular in proverbs and sayings, and only the genitive is dominant in the negative constructions.
The system of factors to define word change paradigms of militi-pseudonyms in the modern Ukrainian language
Authors: Kovtiukh Svitlana 
Published: December 2021

The article is concerned with consideration of specific characteristics of militi- pseudonyms as of made-up personal names of the military, the focus is made on the fact that the problem of normative reproduction of such proprieties in orthography is not set up. It is also emphasized that militi-pseudonyms of Ukrainian heroes of different times, in particular of liberation struggle in 1917–1922, 1938–1950, of today’s Russian-Ukrainian war, are to be written with capital letters and without inverted commas. It is recommended that such information and examples be added to the corresponding paragraph in «Ukrainian Orthography» and determined as a grammar standard.
The publication involves a detailed analysis of relevant factors system necessary to define elementary paradigmatic classes of militi- pseudonyms. On the whole, there have been defined 23 out of 33 possible nouns in the modern Ukrainian literary language, which can be changed, 6 being considered as potential.
Noun declension of proprieties, functioning as the military’s names, is influenced by part of speech characteristics (lexico-grammatical class of nouns, in particular substantivized verbs, numerals, adjectives, participles, adverbs, interjections, etc), by declension type (those of a noun, adjective or referred to differently declined), by lexical meaning, by belonging to a definite class or subclass of onyms, to the person category, definite gender, declension, declension group, short paradigm (only singular word forms), by different word formants, definite stem finals, identity of all word forms or inflexional rows integrity (with or without variant or analytical forms, priority of some of them) within declension paradigm, accentual, contextual, orthographic, morphological, dialect factors, possible deviation from expected forms and changes in the paradigm caused by extra lingual factors (political, military, social, cultural, religious, etc.).
Fenomena of compression, extension and quantitative equacomponence in the syntactic synonymy (based on French fiction of the 20th – the beginning of the 21st c.)
Authors: Lepetiukha Anastasiia 
Published: December 2021

In this article the mono- and polypredicative utterances with syntactic synonymy of French fiction of the 20th – the beginning of the 21st c. are studied in the continuum language → discourse as transforms of virtual (linguistic) primary (pivotal) structures which are actualized in the form of mono- and polysynonymic compressed, extended and quantitatively equacomponential co(n)textually preferential options. The goal of this research is to distinguish the different semantic-structural types of analyzed constructions of modern French fiction and to inversely (discourse → language) reconstruct the primary structure of actualized synonymic transforms.
In the article the transformational method is used to reveal the semantic-structural peculiarities of the pivotal syntagmata and propositions and of the mono- and polysynonymic transforms; and the method of the inverse reconstruction of virtual transformational processes in order to identify all the members of synonymic chains.
It was proved that the redundant synonymic constructions are extended with adverbs, pronouns and predicates (active and passive extension), the compression is manifested most often by the contamination and the semantic and syntagmatic ellipsis. The elliptical constructions are defined in the research as structures with the implicit nominal/pronominal component and with the explicit, explicit-implicit or completely implicit predicate or the structures with the implicit complement where the implicit components are deduced associatively or co(n)textually. The different types of synonymic preferential options with the polysynonymisation at the level of syntagma or utterances were detected in modern French fiction.
It was concluded that the author actualizes the mono- and polypredicative mono- and polysynonymiс constructions according to some communicative intention and planning of narration.
Ukrainian-Rumeika interlingual homonyms and paronyms
Authors: Andrishko Oleh 
Published: December 2021

The article deals with intermittent homonyms and paromies in the Ukrainian and Rumeika.
In 2019, the United Nations announced the International Year of Languages of Indigenous Peoples, and 2022–2032 – an International Decade of Languages of Indigenous Peoples. Rumeika is one of the languages of Greeks of Pryazovia – the indigenous people of Ukraine. Under the terms of the Kuchuk-Carnadzhi Peace Treaty of 1774 between the Ottoman and Russian Empire, the Crimean Khanate became independent. This and the decree of Catherine II caused a wave of the relocation of the Greeks in the Pryazovia. Rumeika has close ties with Modern Greek, while the other language of the Greeks of Pryazovia – Urum – is close to the Crimean Tatar language. For a long time, Rumeika did not have written writing, while in the twentieth century, the efforts of A. Biletskyi for the alphabet developed on the basis of Cyrillic. Despite the fact that in the 20th century Rumeika was an important ethno-forming factor, now it is in a threatening state primarily due to the influence of the Russian language.
Ukrainian and Rumeika languages are in close contact, therefore, the emergence of a large number of inter-digit homonyms and parones. Also, the research of Rumeika is important in view of the fact that it is in front of the disappearance, as well as in geopolitical terms through new social challenges to the population of Ukraine.
The purpose of the article is to find out the peculiarities of the Ukrainian-Rumeika homonyms and paromies, which involves the following tasks: the creation of a dictionary; explaining the values of words; determination of features of inter-life homonyms and paromies in the case of Ukrainian and Rumeika languages.
