An individual genetic profile can be an important tool for ensuring healthy aging. For this reason, numerous studies focus on identifying the genetic mechanisms of aging and longevity and the associated multifactorial diseases. The renin-angiotensin system (RAS) disorders contribute to the formation of pathological conditions associated with cardiovascular disease, cognitive changes, functioning of auditory and visual analyzers, and are the probable predictors of functional disorders in older adults. This article is a literature review of the involvement of RAS gene polymorphisms in the aging processes. The performed analysis of modern domestic and foreign literature has brought new light on the contribution of polymorphic variants of the angiotensinogen (AGT), angiotensin-converting enzyme (ACE) and angiotensin II receptor type 1 (AGTR1) genes to the occurrence and development of pathological conditions and the associated decreases in the intrinsic capacity. The findings suggest that testing for these polymorphisms can be of a practical importance for personalized prognosis and the development of timely preventive programs aimed at improving life expectancy and quality among the elderly.","PeriodicalId":38121,"journal":{"name":"Ekologiya Cheloveka (Human Ecology)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135476714","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}

 BACKGROUND: The intrauterine period of development of the body is the most sensitive to the action of ionizing radiation. Although the effects of prenatal radiation exposure remain poorly understood, it is assumed that antenatal irradiated organisms constitute a risk group for the development of long-term somatic-stochastic effects of radiation exposure.
 AIM: The aim of this study was to analyze the expression of mRNA of cell cycle genes (TP53, MDM2, CDKN1a, ATM) in the long-term in individuals exposed to chronic radiation exposure on the Teche River during intrauterine development.
 METHODS: The study was conducted more than 60 years after the onset of chronic radiation exposure in 170 people. Of these, 54 people were exposed in the prenatal and postnatal periods of development, 80 people were exposed to chronic radiation after birth. The comparison group included 36 people living in similar socio-economic conditions, with an accumulated dose of red bone marrow radiation not exceeding 70 mGr for the entire period of life.
 RESULTS: It has been shown that in the long-term period, residents of the coastal villages of the Techa River, exposed during the periods of antenatal and postnatal development, there is a decrease in the relative mRNA content of the MDM2 and CDKN1a genes compared to the comparison group and people whose chronic radiation exposure occurred after birth. The results of the correlation analysis indicate that there is no dependence of changes in the mRNA expression of the studied genes on the amount of accumulated absorbed dose of intrauterine and postnatal exposure of red bone marrow in the examined people.
 CONCLUSION: It can be assumed that a decrease in the transcriptional activity of the MDM2 and CDKN1a genes in persons exposed to chronic radiation exposure in the prenatal period may play a role in the development of long-term effects of radiation exposure in humans.","PeriodicalId":38121,"journal":{"name":"Ekologiya Cheloveka (Human Ecology)","volume":"87 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135539607","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, a significant number of these studies fail to consider sample size calculation during the planning phase, often relying on basic statistical methods. This not only restricts the usefulness of the data but also increases the risk of drawing inaccurate conclusions.
 The primary focus of this article is to provide a step-by-step guide for the sample size calculation process. By following our guidelines, researchers can ensure that their cross-sectional studies are adequately powered to yield meaningful and reliable results. We recognize the importance of tailoring sample size calculations to the specific objectives and data characteristics of each study, and thus our approach is flexible and adaptable.
 While numerous software options exist for sample size calculation, we use G*Power software for all examples in this paper. Each step in our guide is complemented by examples and detailed screenshots, ensuring that the material is both comprehensible and practically applicable. Moreover, we interpret every dialog box and screenshot to make the users comfortable with the software.
 The scientific quality of a study depends on detailed planning, a clear statement of the problem and the precise formulation of statistical hypotheses that are tested using the most appropriate analytical methods. Central to this process is the determination of the appropriate sample size. We hope that this article will serve as a valuable guide in the planning stage of a study, helping researchers to address a wider range of issues and reliably estimate the associations between selected exposures and the outcomes of interest with sufficient statistical power.","PeriodicalId":38121,"journal":{"name":"Ekologiya Cheloveka (Human Ecology)","volume":"6 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135218262","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}

Despite the ease of diagnosing AH and the availability of treatment, about half of AH patients are not aware of their disease, and don't take the recommended drugs. In combination with the harsh climatic conditions of the northern regions, this can lead to early myocardial infarctions and strokes. The aim is to study the association between atmospheric air temperature and blood pressure (BP) among the adult population in the Arkhangelsk. Methods. The data of blood pressure measurement in 2342 participants of the \"Know your heart\" study in the age group of 35-69 years, conducted in Arkhangelsk in the period from November 1, 2015 to October 31, 2017, were used. Each BP measurement was associated with time-corresponding readings of atmospheric air temperature in the Arkhangelsk, which were recorded by the city meteorological station with a frequency of 8 times a day. To assess the effect of air temperature on BP, a linear regression analysis was used separately for the warm (April 16October 15) and cold (October 16April 15) seasons. Results: In the warm season of the year, in the group of participants without AH and in those with treated AH, high values of atmospheric air temperature (17.5-26.5С) relative to the average level (8.8-12.2С) cause a decrease in systolic blood pressure (SBP) at 7.9 mm Hg (p=0.004) and 8.5 mm Hg (p=0.012), respectively, and diastolic blood pressure (DBP) by 5.1 mm Hg (p=0.002) and 4.5 mm Hg (p=0.021), respectively.

 Material and methods. The theoretical stage of the work was aimed at determining the key physical and geographical factors of the environment and assessing the indicators of social and criminal tension in 14 model regions of Russia.
 1815 students, men and women aged 18-28, representatives of the population of the model regions participated in the field stage of the work. The psychological status of the respondents was determined by assessing the indicators of the Freiburg multifactorial personality questionnaire; accentuations of character, suggestibility, frustration, irritability, adventurousness; vectors of social activity and destructiveness; prosociality-asociality; type of behavioral activity (A-B). Identification of the experience of using psychoactive substances was carried out by self-assessment of the subjects. Correlation analysis was used for statistical data processing.
 Results. The average annual temperature is negatively related to the level of crime (p=0.012), the number of abortions (p=0.0001), the degree of alcoholization (p=0.004), the level of smoking (p=0.011) in society.

 AIM: To evaluate the components of the auditory evoked potential P300 and N2, parameters of heart rate variability in practically healthy young people aged 16-17 years living in different climatic and geographical conditions of Russia.
 MATERIAL AND METHODS: The study involved young people aged 16-17 (n = 156) from Arkhangelsk (6433ʹ s. s.), Nadym (6532ʹ s. s.) and Simferopol (4457ʹ s. s.). The assessment of the autonomic nervous system was carried out according to the parameters of heart rate variability (HRV) on the agro-industrial complex \"Varikard\". Registration of P300 and N2 components was carried out on the Neuron-Spectrum-4/VPM electroencephalograph (Neurosoft, Russia), using the oddball paradigm.
 RESULTS: The predominance of sympathetic nervous system activity in the regulation of heart rhythm and the lengthening of N2 latency was revealed in young people of the city of Nadym. In young people of Arkhangelsk and Simferopol, there were no differences in the parameters of HRV and components of the auditory evoked potential of p300.

The revealed regional features of mortality by causes, as a rule, are not local in nature, but spatially determined.
 AIM: Determination of temporal tendencies of spatial regularities of the working-age population mortality from the main causes (on the example of the Republic of Bashkortostan) and identification of territorial factors that determine it.
 METHODS: This study used data on the mortality in municipalities (54 municipal districts, 20 urban districts and urban settlements) aggregated by 6 main causes of death in the dynamics of 20022020. The analysis included estimation of the Moran's index and the spatialpanel data modeling.
 RESULTS: Spatial dependencies are most noticeable for diseases of the circulatory system, some infectious and parasitic diseases, as well as for external causes. The level of crimes in a given region (male: p0.046; female: p0.019) has a negative impact on mortality from diseases of the circulatory system in the working-age population among men and women; for men, the volume of gross municipal product (GMP) has an additional effect (p 0.046). Factors that reduce mortality from external causes among able-bodied men and women are the growth of the GMP (male: p0.0098; female: p0.003 - for women), the increase in the number of doctors per 10,000 people of the population (male: p0.001; female: p0.037) and availability of nursing staff (male: p0.026; female: p0.005). For men, a significant impact on mortality from external causes was additionally exerted by crime (p0.028), and for women, by the availability of hospital beds (p0.030).

However, only in the last 30 years daily data with sufficient validity are in use, necessitating the systematization of the latest research evidence.
 Aim: To conduct a systematic selection and qualitative synthesis of published information on the associations between ambient air temperature and suicide over the past 30 years.
 Methods: A systematic review using PRISMA criteria. Studies published in peer-reviewed journals from January 1990 to April 2022 in PubMed and eLIBRARY in Russian or English, respectively, comprised the study base. The selection of articles was made according to the following criteria: original research; data on the ambient temperature in the studied period of time are presented and the upper part of the temperature range was studied; data on suicide counts are available.
 Results: Of the 1932 identified articles, 32 empirical studies with the number of cases ranging from 225 to 1067333 from 26 countries were included in the qualitative synthesis. In addition to mean temperatures, the minimum and maximum temperatures, as well as the calculated apparent mean, minimum and maximum temperature were used. By design, most studies had ecological or case-crossover design. Generalized Additive Models (GAM) were used as the main analytical tools, and in multicenter studies the results were obtained using meta-regression. The results were presented as relative risks or the percentage increase in the number of suicides with an increase in temperature by 1C. Virtually all studies reported a significant linear relationship between the temperature and suicide rates, but effect sizes varied between countries. The effect was more pronounced in temperate climate, in men and people over 65 years of age.
 Conclusions: Most of the studied suggest a direct relationship between high air temperature and the number of suicides in different latitudes.
