The aim of this study was to identify significant changes in the morphological profile of adolescents in Penza and Penza region over 15 years. Material and methods. The object of the study were 492 people of both sexes, 16 to 21 years of age, born and permanently residing in Penza and settlements of Penza region, divided into two groups according to the year of birth (group 1 – born in 1986–1990, 2 group – born in 1999–2004). Anthropometry and somatometry were carried out by the method of V.V. Bunak with subsequent comparative analysis of statistical indicators. For a comparative assessment of the level of physical development and identification of significant differences between the two groups, the following index methods were used: body mass, Rohrer, Erisman, Pignet, Rees-Eysenck, Tanner. Results and discussion. Based on the results of the study, it was concluded that Penza residents of 1999–2004 birth, compared with predecessors, there was a significant increase in the studied absolute anthropometric parameters with a simultaneous shortening of the hand and shin length. Among the representatives of the modern youth of the region, when compared with the group of 1986– 1990 birth, the number of people with mesomorphy increased by 2.2 times, the number of people with overweight – by 1.5 times, the number of individuals with a narrow chest – by 1.3 times, the number of cases of a low degree of physical development, hypersthenic type (according to the results of calculating the Rees-Eysenck index) – by 1.2 times, at the same time the number of normosthenics increased by 1.1 times (according to the results of calculating the Pignet index). Conclusions. Comparative analysis showed significant changes in the constitution of the autochthons of Penza region of adolescents over 15 years.","PeriodicalId":24058,"journal":{"name":"Сибирский научный медицинский журнал","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680971","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}

Material and methods. The paper is based on the results of morphometric study of corrosion casts of splenic venous vasculature of 64 people (32 men, 32 women) at the age of 21 to 60 years (32 first period of adulthood, 32 second period of adulthood), deceased from sudden death and accidental causes. The study was conducted in compliance with ethical principles, including the World Medical Association’s Declaration of Helsinki. The diameters (D) and lengths (L) of the venous segments constituting BU were measured. Splenic venous vasculature was represented as a system consisting of three types of BU: 1 BU – the proximal segment diameter (D) is less than the sum of the diameters of distal segments (dmax and dmin) associated with it, D < dmax + dmin; 0 BU – D = dmax + dmin; 2 BU – D > dmax + dmin. Results. All three kinds of BUs were identified; there was a significant relationship between the relative number of BUs of different kinds, sex and age group; the sizes of all three kinds of BUs were determined; 1 BU was the largest and 0 BU was the smallest; 0 BU was the most symmetrical and 2 BU was the most asymmetrical; the relative number of 1 BU decreased, 0 BU increased, and 2 BU practically did not change in the direction from proximal to distal parts of the channel. BUs of the 1st kind have the largest diameter of proximal segments, while 2 BUs occupy the middle position in the range of values of the investigated parameters. The smallest diameter belongs to 0 BU. As for the length of segments L, the maximum values are typical for 1 BU, the minimum – for 2 BU, and the middle position in the series is occupied by 0 BU. Conclusions. The results obtained can serve as a foundation for the creation of a morphometric standard of splenic venous vasculature, and should be considered in its numerical modelling.","PeriodicalId":24058,"journal":{"name":"Сибирский научный медицинский журнал","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680954","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}

Aim of the study was to clarify the mesoscopic anatomy and histotopography of different parts of the LAA walls in normal human fetuses of 16–22 gestation weeks. Material and methods. We prepared serial histotopograms of the left atrial appendages from 10 normal human fetal hearts stained by Masson trichrome, orcein and fast green. We studied slides by means Olympus CX microscope, TOUPCAM U31S digital camera, and ADF-Image program for measuring. Using a Carl Zeiss EVO LS 10 scanning electron microscope at a magnification of 15–5000 times, three samples were examined using the freeze-chip method. Results. Having measured the outer walls of the LAA intertrabecular spaces, we found that at the level of the middle third of the left atrium, their thickness is minimal in the posterior wall (80 [61–97] μm) (median [lower quartile; upper quartile]), thickness in the anterior wall is 142.9 ± 33.2 μm (mean ± standard deviation) (101 [79–192] μm). At the level of the coronary sulcus, the same parameters were 143.7 ± 23.6 µm (147.5 [90–180] µm) and 137.4 ± 33.9 µm (101 [68–195] µm), respectively. Downward, LAA posterior wall increased about 1.8 in thickness, whereas the thickness of the anterior wall was the same. The endocardium showed the same thickness in all locations. Microanatomically, the LAA myocardium never discovered to build from distinct layers but “anatomical syncytium” or seldom bundles. Collagen and elastic layers were common for endocardium, rare for epicardium. Endocardial elastic fibers interweaved in the underlying collagen so the distinct boundary lacks there. Conclusions. Mesoscopic and microanatomical features of LAA walls in human fetus consist of variable thickness at different levels, unlayered but “syncytial” myocardium, muscleless areas, elastic and collagen layers of the endocardium.","PeriodicalId":24058,"journal":{"name":"Сибирский научный медицинский журнал","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141682323","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}

Tereshchenko","doi":"10.18699/ssmj20240311","DOIUrl":"https://doi.org/10.18699/ssmj20240311","url":null,"abstract":"Adolescence is one of the most difficult period in the person’s life. Adolescent behavior is influenced by many factors, including the social environment, internal attitudes and hormonal levels. One of the important hormones that can change behavior is oxytocin – an extremely important prosocial neuropeptide that influences social bonding from an early age. The effect of oxytocin on the psycho-emotional state is quite individual and may depend on age, gender, ethnocultural factors, social environment, the presence of stress factors, and personality traits. The results of the studies indicate the relationship between the increased concentration of oxytocin and the presence of developed social contacts. The aim of this work was to identify an association between psychosocial characteristics in adolescent of different gender and rs53576 polymorphism of the oxytocin receptor gene. Material and methods. Psychological and genetic testing of adolescents aged 11–18 living in the territory of the Angara-Yenisei macroregion was carried out. Mental health assessment was carried out using the Russian version of the questionnaire “Strengths and difficulties” by R. Goodman. Results and discussion. The rs53576 OXTR AA genotype is more frequent in boys than in girls (20.8 % vs. 14.3 %, p = 0.03). The association of the rs53576 OXTR A allele with social behavior disorders and depression was previously shown. Boys carrying the AA genotype have significantly higher scores (borderline values) on the scales of “Emotional symptoms” and “Problems communicating with peers” compared with carriers of the GA and GG genotypes. Conclusions. Evidences of differing individual psychosocial consequences of high activity of the oxytocinergic system, depending on the context of the social environment, allowed us to formulate the “hypothesis of the social significance of oxytocin”. Problems in communication with peers in adolescents with pronounced social empathy and altruistic personal characteristics can be successfully overcome. Both the general orientation of the pedagogical process towards the approval of prosocial behavior, and socially significant personalities, whom adolescents can perceive as an example to follow, can help in many ways.","PeriodicalId":24058,"journal":{"name":"Сибирский научный медицинский журнал","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680586","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}

This artery supplies blood to the pancreatic neck region, the area where, in the vast majority of cases, pancreatodigestive anastomosis is performed. Material and methods. A systematic literature review was conducted using the PubMed, Embase, CyberLeninka, and GoogleScholar bibliographic databases. The following keywords and their combinations were used: «cranial trunk», «superior mesenteric artery», «splenic artery», «common hepatic artery», «dorsal pancreatic artery», «pancreatic body and tail arteries», «pancreatic isthmus blood supply», «pancreatic anatomical segment arteries», «anatomy», «variants», «arterial anastomoses» and «anomalies». Results and discussion. Frequency of dorsal pancreatic artery was 79–100 % according to the data of anatomical investigations; radiological ones – 64.4–100 %. Its main sources were the splenic artery – from 22.22 to 80 % according to anatomists, from 13.5 to 100 % according to radiologists; the cranial trunk – 3–33.3 and 8–27.75 % respectively; the superior mesenteric artery – 1.8–25 and 3.8 % respectively; the common hepatic artery – 12–24 % regardless of the research methods. The course of the dorsal pancreatic artery and its division into the terminal branches (prepancreatic and inferior pancreatic arteries) was characterized by relative constancy. Conclusions. This review summarizes world literature data devoted to the topographic anatomy of the splenic artery and its pancreatic branches involved in the blood supply of the body and tail of the pancreas.
