Issues affecting the importance of these proteins in the pathogenesis, adaptation and life cycle of the virus are discussed. Structural multifunctional proteins are biomarkers of increased contagiousness and pathogenicity of SARS-CoV-2, forming its pathogenetic and adaptive potential. The multifunctionality of the structural proteins of the new coronavirus allows it to respond quickly to fluctuations in the conditions of existence through the use of alternative approaches to implement the mechanisms underlying its pathogenetic potential. Currently, the structure, properties, functions and role of structural proteins of SARS-CoV-2 are being actively studied, which is an actual vector of research that allows us to decipher the mechanisms underlying its high contagiousness, pathogenicity, adaptation, and in the future to evaluate possible ways of forming its new variants and develop a strategy and tactics of emergency response when it appears new strains.The prospects of further study of the structure and properties of structural proteins for solving the priority tasks of the present time on the creation of modern domestic vaccines and effective methods of diagnosis, treatment and prevention of a new coronavirus are noted.The authors analyzed scientific publications from various databases of electronic libraries, such as PubMed, e-library, CyberLeninka, etc.","PeriodicalId":18314,"journal":{"name":"Medical Herald of the South of Russia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83362285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, to date, there is little data regarding the factors for the development of endometrial polyps in reproductive-age women. This fact determined the direction of our study. A search was conducted among scientific papers in the Science Direct, CochraneLibrary, PubMed databases by keywords (polyps, endometrium, risk factors, reproductive age) for 1994–2022. As a result of the analysis of the scientific literature, we came to the following conclusions: 1. The prevalence of endometrial polyps depends on the studied population, while the actual prevalence is difficult to determine, since the endometrial polyps can be asymptomatic and regress over time. 2. Implementation of endometrial polyps, apparently, depend not on one, but on many factors: genetic, hormonal, metabolic, medicinal. 3. Increasing the amount of endogenous estrogen, the introduction of exogenous estrogen without progesterone component and age are the most important predisposing risk factors for the development of endometrial polyps.","PeriodicalId":18314,"journal":{"name":"Medical Herald of the South of Russia","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78877600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their mechanisms of action are not yet fully understood. Hormone-replacement therapy (HRT) and surgeries modify sex characteristics. According to the biomedical model, perception of one's own sex characteristics is the primary contributor to gender dysphoria. Perception of the person in the wrong gender by others and/or their negative reaction is another (and less explored) mechanism leading to gender dysphoria. In order to conduct high-quality epidemiological studies, it is vital to take into consideration and measure intermediate outcomes, such as the degree of feminization/masculinization and the person's perceived gender. Sex characteristics are measurable, so it is possible to develop a feminization/masculinization scale. However, the task is complicated by the fact that various sex characteristics contribute unequally to the person's perceived gender, for which reason they should enter the scale with different coefficients. While such coefficients might be derived from controlled experiments, gender attibution in the real world depends on innumerable social factors. Reaction by others on the person's perceived gender is an additional factor affecting social gender dysphoria. Determining biological factors affecting the effectiveness of HRT in feminization and masculinization is a separate problem.","PeriodicalId":18314,"journal":{"name":"Medical Herald of the South of Russia","volume":"450 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76332575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the studied anomalies of lymphatic vessels, lymphangioma is most often mentioned — a congenital benign tumor consisting of many cysts of various sizes. Detection of primary fetal lymphangioma in the early stages of intrauterine development is extremely rare. The purpose of the study: to report a case of early diagnosis of congenital cystic lymphangioma and lymphedema of the left lower limb of the fetus. Congenital (primary) peripheral lymphedema, limb lymphangioma is associated with a malformation of the lymphatic system. Taking into account the fact that operative methods of correction of all types of primary lymphedema are considered unreasonable and ineffective, the main attention requires timely detection of this congenital malformation during screening studies of the fetus and the issuance of recommendations for the management of pregnancy, up to termination for medical reasons. It is necessary to raise the issue of genetic counseling of the couple and conducting the necessary genetic studies. The use of modern diagnostic methods allows for the prevention and treatment of abnormalities in the development of the lymphatic system at an earlier stage of the intrauterine period.","PeriodicalId":18314,"journal":{"name":"Medical Herald of the South of Russia","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82728831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and methods: 120 patients with AH were divided into 3 groups: group 1 — 46 patients with AH and clinically manifested AALE, group 2 — 39 patients with AH and asymptomatic AALE, group 3 — 35 patients with AH without AALE. The patients of each group were divided into 2 subgroups: the 1st subgroup — not receiving statins, the 2nd subgroup — taking statins. All patients underwent laboratory and instrumental studies, including the determination of vascular stiffness parameters using the Vasotens software («Peter Telegin», Nizhny Novgorod) and ultrasonic triplex scanning of the arteries of the lower extremities. Statistical data processing was carried out using Microsoft Office Excel 16 (2015, Microsoft, USA), Statistica 10.0 (StatSoft, USA), IBM SPSS Statistica 26.0 (IBM, USA). Results: lower values of total cholesterol were found in patients of the 2nd subgroup of all studied groups (p<0,05), as well as lower values of low-density lipoprotein cholesterol (LDLС) among patients of the 2nd subgroup of the second and third groups (<0,05). In patients of all groups, when using statins, the target values of LDLC were not achieved. Lower values of the arterial stiffness index (ASI) and augmentation index (AIx) were found in patients of the first group of the 2nd subgroup receiving statins in comparison with patients of the 1st subgroup (p<0,05). In patients of the second group of the 2nd subgroup, while taking statins, there was a clear trend towards a lower ASI value compared to the 1st subgroup (p=0.07). Conclusions: the use of statins in patients with hypertension and AALE of varying severity, despite the lack of achievement of target levels of LDLC, contributed to a decrease in vascular stiffness, and, consequently, a decrease in cardiovascular risk.","PeriodicalId":18314,"journal":{"name":"Medical Herald of the South of Russia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90942404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results: statistically significant changes were revealed in the profile of organic acids in the studied women at the levels of lactic, pyruvic and 4-hydroxyphenylpyruvic acids. In women with missed abortion, the change in the lactate / pyruvate. In all women with missed abortion, 4-hydroxyphenylacetic were determined, in contrast to women with a progressing pregnancy, combined with morpho-immuno-histochemical features (pronounced focal necrosis, venous fullness, lymphohistiocytic infiltration, increased levels of HLA-DR, CD 16, CD20 expression, reduced VEGF and LIF expression). Conclusion: missed abortion is associated with the accumulation of intermediate metabolites of tyrosine catabolism (4-hydroxyphenyacetic, 4-hydroxyphenylpyruvic and homogentizic acids), which, despite normal levels of TSH and T4, may reflect organ dysfunction. Timely correction of iodine deficiency in the pre-conception period after missed abortion can be a criterion for a successful subsequent pregnancy.
