© 2021, The Author(s). Background: The morphometric analysis of the individual bones of the human skeleton can be used to estimate the sex of unidentified corpses. Our aims were as follows: to test whether thyroid cartilage can be used for forensic purposes as a predictor of biological sex; to establish the level of sexual dimorphism of the thyroid cartilage in a sample of adult subjects from a population of European Russia; and to test the accuracy of the morphometric parameters obtained from the thyroid cartilage. Results: The thyroid cartilage from 100 adults of known age (50 males and 50 females) was obtained during forensic examination; morphometric tests were conducted using Vernier Digital ROKTOOLS ABS DIN 862 0-200/6 inch with measurement accuracy ± 0.01 mm. The measured parameters were N = 31 for each subject. Intra- and inter-observer reproducibility was tested. Multivariate statistical analysis was applied to the measurements. To check the data set for normal distribution, the Kolmogorov-Smirnov test was used. Finally, to estimate the sex of the observed individuals, a stepwise discriminant analysis was conducted, using the Wilks’ lambda selection method. The most significant parameters were the outer distance between bases of inferior horn; the inner distance between distal ends of inferior horns; distance between distal ends of left superior and inferior horns; left superior horn length (distance between left superior horn distal end and base); distance between superior and inferior notches; thyroid angle; left lamina height (vertical line along left lamina middle); horizontal distance between anterior intermedium line and the right lamina posterior edge; distance between inferior thyroid notch and line connecting left and right thyroid laminae; and left superior horn thickness at mid-line. The stepwise discriminant analysis resulted in an equation with ten parameters. Conclusions: The results of the current study indicated that in the European Russian population, the equation obtained in the stepwise discriminant analysis makes it possible to predict sex with a probability of 100% on the validation set. On the test set, the resultant accuracy was 100% for females and 100% for males. Our findings confirm the scientific evidence that the thyroid cartilage has a pronounced sexual dimorphism.

Background: With an increasing aging population and a lower ratio between the active and the dependent population, population aging is considered a global social and health challenge, associated with increased demand in health care needs and social pension. This study projects the Greek and Cypriot population to guide future planning of social and health policies and services. Methods: The total population by sex and age groups, Total Fertility Rate (TFR), life-expectancies at birth and Potential Support Ratio PSR (persons aged 20–64 years per person 65+ years) are projected probabilistically by the year 2100 using Bayesian hierarchical models and United Nations’ population data for Greece and Cyprus from the period of 1950 to 2015. Results: The TFR is projected to be around 1.5 children per woman in 2050 and around 1.75 in 2100 for both countries, with all values of prediction intervals being around or below the Replacement level fertility. PSR is expected to decrease remarkably and be 2.5 in 2050 and 1.6 in 2100 for Cyprus while for Greece it will be around 1.5 for both years 2050 and 2100. Life-expectancy is expected to increase to 84 years for men and 87 years for women in 2050 and 90 years for men and 94 years for women in 2100 for both countries. The share of the population aged 65 years and over is projected to increase in both countries and be the one third of the population by 2100. Conclusions: Greece and Cyprus will acquire the characteristics of an aging population, putting a significance pressure on the social and health systems of both countries. Both countries should reform their social and health policy agenda to confront population aging and its consequence. They should adopt fertility incentives and family policies to increase fertility and migrants’ inclusiveness policies to improve the demographic structure and the economic activity. The national health systems should promote prevention strategies at the primary health sector and promote healthy aging while health research policy should aim to promote research in innovative technologies and digital health to create assistive technology for self-care and greater independence of older people.

Sandwich-like docking configurations of the heterodimeric complex of NFR5 and K1 Vicia sativa receptor-like kinases together with the putative ligand, Nod factor (NF) of Rhizobium leguminosarum bv. viciae, were modeled and two of the most probable configurations were assessed through the analysis of the mutual polymorphisms and conservatism. We carried out this analysis based on the hypothesis that in a contact zone of two docked components (proteins or ligands) the population polymorphism or conservatism is mutual, i.e., the variation in one component has a reflected variation in the other component. The population material of 30 wild-growing V. sativa (leaf pieces) was collected from a large field (uncultivated for the past 25-years) and pooled; form this pool, 100 randomly selected cloned fragments of NFR5 gene and 100 of K1 gene were sequenced by the Sanger method. Congruence between population trees of NFR5 and K1 haplotypes allowed us to select two respective haplotypes, build their 3D structures, and perform protein–protein docking. In a separate simulation, the protein-ligand docking between NFR5 and NF was carried out. We merged the results of the two docking experiments and extracted NFR5–NF–K1 complexes, in which NF was located within the cavity between two receptors. Molecular dynamics simulations indicated two out of six complexes as stable. Regions of mutual polymorphism in the contact zone of one complex overlapped with known NF structural variations produced by R. leguminosarum bv. viciae. A total of 74% of the contact zone of another complex contained mutually polymorphic and conservative areas. Common traits of the obtained two stable structures allowed us to hypothesize the functional role of three-domain structure of plant LysM-RLKs in their heteromers.

Results of medico-sociological studying of specifics of social installations of the population concerning HIV-infected citizens are presented in article. The conducted research shows that now the deficiency of objective information on a problem of HIV-infection/AIDS is observed, and negative installations of russians concerning HIV-infected persons still remain widespread social practice. Authors note that despite efforts of the state, medical and public organizations on increase in level of tolerance of the population concerning HIV-infection/AIDS, the fact of establishment of the diagnosis «HIV-infection», besides problems of medical character, causes change of the social status HIV-infected and also attracts extensive social and reputation losses – that, in general, distances the HIV-infection carrier from other population and intensifies social inequality.

The conducted research shows that now HIV- infection is associated at Russians with consumption of drugs and insufficient social responsibility of youth and also with risks at delivery of health care and implementation of cosmetic procedures. Authors note that in spite of the fact that development of vaccine against HIV-infection/AIDS is represented to the interviewed Russians one of possible ways of overcoming epidemic, respondents perceive personal participation in vaccination against HIV- infection/AIDS as a high-risk step.

Results of the medico-sociological research directed to studying of the ideas of the HIV-infected widespread in modern Russian society are presented in article. The obtained data have allowed to design a modern social portrait of the HIV-infected Russian. Now in representations of Russians the typical HIV-infected - the young childless and single man regardless of sexual orientation who is living in the large city, having an average special educations or being in process of that receiving which level of income we will compare with a living wage. The HIV-infected has been infected as a result of a youth error (the unprotected sexual contact or the intravenous use of drugs) and lives with this diagnosis several years, leads a risk-free life more often, at the same time usually hides the diagnosis and separates from social communications.

We studied minor variants within two tick-borne encephalitis virus (TBEV) populations with a common ancestor: the mouse brain-adapted variant EK-328c and the tick-adapted variant M. High-throughput sequencing with custom amplicons from RTPCR viral RNA was performed on Illumina MiSeq 2*250 paired-end v2 chemistry. Using the LowFreq program (default settings) and Sanger-sequenced consensus as a reference, variants with an abundance of 1% and above within the studied populations were identified. Using the obtained data in the context of our previous studies, we concluded that TBEV variants, which are different from the major population phenotype and can become a major part of the viral population under favourable environmental conditions, can exist at abundances of less than 1% in the long-term. The comparison of our data with the literature allowed us to conclude that the laboratory variant EK-328c and variant M have similar SNV counts to TBEV variants from natural populations and some fast-evolving RNA viruses.

Therefore it is necessary to study factors with most substantial impact on regional morbidity and mortality for elaboration of targeted programs of preventive measures aimed at definite population groups. Purpose of this study was to perform analysis of differences of mortality from cardiovascular diseases (VVD) of Moscow region inhabitants of various gender and age. Materials and methods. Data on 2016 mortality of Federal Service of State Statistics (Rosstat) and territorial service of state statistics of the Moscow Region were used in this analysis. Analysis was conducted for men and women divided in age groups ≤50, 50-59, 60-69, and ≥50 years. Diseases were classified in accordance with 10 th Revision of International Statistical Classification of Diseases (ICD10). Results. Population of the Moscow Region territory on January 1, 2016, amounted 7 318 647 (men 46.2, women 53.8%, persons of working age 58.9%). Contribution in the mortality structure of chronic ischemic heart disease (IHD) and cerebro-vascular diseases in women was greater than in men (80 vs. 68%, respectively, р<0.0001). Contribution of acute IHD, IHD unrelated heart diseases, and vascular diseases in men was significantly greater than in women (30 vs. 18%, respectively, р<0.0001). In the age group over working age mortality indexes were substantially higher compared with those in working age. In men these indexes became 10-20 times while in women - 30-130 times higher. Conclusion. Despite positive dynamics of mortality from diseases of the circulatory system (45.3% lowering from 2008 to 2016) it is necessary to strengthen efforts directed to correction risk factors of IHD and implementation of timely diagnostics and correction of IHD unrelated diseases.

The special technical means which are powerful sources of EMP in the range of frequencies of 0.02 – 6.00 GHz by which workers in the course of their production and operation and also the population which has appeared in a radiation zone can be affected, are developed for the suppression of radio-frequency signals of control of explosive devices. Aim of the study. Scientific justification and development of hygienic requirements for the safe use of systems of suppression of radio lines of control of explosive devices (SS RCED). Material and methods. The calculation methods for determining the EMF intensities created by different types of SS RCED (1500 calculations) were used, more than 250 measurements were carried out at different distances from 5 types of SS RCED in the open area and in the offices. Results. Hygienic investigations have allowed to point out 5 categories of the irradiated contingents for which hygienic regulations of EMP on the basis of the analysis of the standard and methodical documents acting in the Russian Federation have been proved. Calculations and natural measurements of the EMP levels from various types of SS RCED in rooms and in the open territory are taken. The technique of forecasting of conditions of radiation taking into account their technical characteristics (range of frequencies, power, etc.), the time of the exposure and distances from sources is offered. The algorithm of carrying out a hygienic assessment of conditions of radiation of personnel and population from SS RCED and a complex of preventive actions are developed. Discussion. Protection of workers by production, service, and operation of SS RCED, has to be carried out by restriction of the time of the impact of EMP taking into account power expositions at different distances from a source, and the population - by determination of safe zones of stay taking into account categories of the irradiated contingents. The technical actions including the organization of remote control of SS RCED and application of means collective (shielding) and/or individual protection are offered. Conclusion. The conducted complex research allowed justifying hygienic requirements for the production and operation of SS RCED and developing the project of SanPiN 2.1.8/2.2.4.xxxx-18 «Sanitary rules and standards of safe use of systems of suppression of radio lines of management of explosive devices of the range of frequencies of 0,02–6,00 GHz».

Against the background of the remaining high rates of infection spread beyond the borders of risk groups, a series of the negative phenomena aggravating an epidemiological situation on HIV-infection and other socially important diseases is observed (tuberculosis, hepatitises, etc.): depression of the general indicators of health of the population, urbanization, complicating of life rhythm, wide circulation of dependences on psychoactive agents, and, above all - serious transformation of institute of family, liberalization of sex behavior, of traditional family values. Now in representations of Russians the typical HIV-positive-a young childless and single man regardless of sexual orientation who is living in the large city, having an average special educations or being in process of its receiving whith level of income comparable to average one. The HIV-positive has been Infected as a result of a youth error (unprotected sexual contact or the intravenous use of drugs) and lives with this diagnosis several years, leads a risk-free life more often, at the same time usually hiding the diagnosis and separated from social communications. Existence of this diagnosis involves social trouble and the social not approved behavior, but if the disease affects the loved one, many Russians are potentially ready to give moral and psychological support (56%), financial support (including in purchase of drugs), the help in search of necessary experts and visit of the medical organizations (6,9%) and also to care for the HIV infected and their children (6%). According to authors, the widespread negative perception of people with "HIV-infection" diagnosis is in many respects caused by insufficient informing the population on HIV-infection/AIDS problems.

© AUTHORS, 2018. The area of invasive species Aedes albopictus and Aedes aegypti is expanding. Precise identification and understanding of the genetic diversity of invasive mosquito populations allows us to develop appropriate control methods. Endosymbiotic bacterium Wolbachia pipientis has different effects on their arthropod hosts and can influence the transmission and spread of the pathogens. The objective of the presented study was molecular-genetic identification of the Aedes mosquitoes collected in sampling sites on the Black Sea coast from 2007 to 2017; determination of genetic variability of Ae. aegypti, Ae. albopictus and their symbiotic bacteria Wolbachia; assessment of mosquitoes ability to be infected and to spread parasitic Dirofilaria. Another objective was obtaining the genetic characteristic of laboratory strain Ae. aegypti IMPITM. We investigated two markers of nuclear and mitochondrial DNA from Ae. albopictus and Ae. aegypti and compared them to DNA from Ae. cretinus and Ae. koreiсus sympatrically inhabiting the territory, as well as to one of Ae. aegypti from a laboratory line. The study of nuclear and mitochondrial DNA revealed a low level of variability in the invasive mosquitoes Ae. albopictus and Ae. aegypti collected at different collection sites and in different years. More than a half of Ae. albopictus were infected with Wolbachia, two strains of bacteria, wAlbA and wAlbB, occur in the Ae. albopictus population on the Black Sea coast. Total infection of Ae. aegypti and Ae. albopictus with dirofilariae was 1.8 %. Dirofilaria immitis was found only in mosquito abdomen, larvae of infective stage L3 were not found. D. repens larvae developed to the infective stage in the mosquitoes of both species.

The enzyme-linked immunosorbent assay (ELISA) and the neutralization test (NT) are often used to determine the level of seropositive population and to evaluate the immunogenicity of vaccines. ELISA provides information on the total pool of antiviral antibodies, while NT allows the antiviral protection level of a person to be estimated. It is assumed that the 1: 100 titer in ELISA and the 1: 10 titer in NT are protective. Obviously, the ratio of the total pool and virus neutralizing antibodies can vary as a result of natural immunization or vaccination. In this study, two methods were used to study the blood serum samples taken in a group of inhabitants of the Sverdlovsk region aged from 1 to 60 years. The samples were collected before immunization and 30 days after two immunizations with inactivated vaccines against tick-borne encephalitis of different manufacturers. Immunizations were performed either according to a standard scheme (30-day interval between immunizations), or according to an emergency scheme (14-day interval). It was shown that the data on the presence of antiviral antibodies in protective titers obtained by ELISA and NT were consistent in more than 85% of cases. The discrepancies between the data are due, in the first place, to the difference in the sensitivities of the two methods. The proportion of seropositive people according to NT data is always greater than that according to the results of ELISA. Nevertheless, among 174 children, about 5% of recipients after a double immunization were seropositive according to ELISA, but did not have neutralizing antibodies in protective titers.

© 2018 Czech Academy of Sciences. The population structures of different species of Calliphoridae flies are highly diverse at different locations. We investigated populations of the Eastern European L. sericata using chaetotaxy and eight microsatellite loci. Our results strongly indicate that a panmictic population of L. sericata exists in the area studied, possibly with a high rate of intra-population gene flow. Analysis of chaetotaxy also supports the panmictic population hypothesis.
