Rationale. There are numerous works in the literature covering issues of age, sexual and bilateral variability of the cerebral arteries in adults. There is no information on morphometric parameters of the cerebral arteries in children. Objective: To present data on the morphometric characteristics of the paired arteries of the brain in children during early childhood, taking into account sexual and bilateral variability. Material and methods. Samples of precommunication segments of the anterior (ACA), wedge-shaped parts of the middle (MCA), precommunication segments of the posterior (PCA) cerebral, intracranial parts of the vertebral (VA) arteries and cerebral parts of the internal carotid arteries (ICA) seized during autopsy of corpses of 18 children from early childhood (1-2 years) who died for reasons not associated with acute vascular cerebral pathology. Outside (LP) and inside diameters (DP), wall thickness (TC) were determined. Results. The mean values of the above parameters were respectively: ACA - 1,760,04 mm, 0,140,01 mm and 1,490,04 mm; MCA - 2,070,04 mm, 0,140,01 mm, 1,790,04 mm; PCA - 1,830,06 mm, 0,130,01 mm, 1,550,06 mm; VA - 2,080,06 mm, 0,150,01 mm, 1,770,05 mm; ICA - 2,600,05 mm; 0,150,01 mm, 2,300,05 mm. RD and PD ACA predominate in the right hemisphere by 17.3 (p = 0.009) and 19.9% (p = 0.016), respectively. RD and DP PCA prevailed in boys, respectively, by 9.1 (p = 0.019) and 12.9% (p = 0.006). Conclusion. Average data of RD, TC and DP of paired arteries of the brain in children in the period of early childhood were obtained. Most parameters have no confirmed bilateral and sexual differences. The findings may be useful for interpreting non-invasive research methods and should also be considered in the design and adaptation of intravascular devices for use in pediatric practice.

Being one of the aspects of the morphological constitution, the component composition of the body reflects the state of metabolic processes in the body and can serve as a kind of predictor of the development of various pathological conditions. One of the most accessible for researchers and widespread methods is the determination of body mass index, which ensures the comparability of the results obtained by different authors. The aim of our study was to systematize and compare the literature data of domestic and foreign authors on body mass index in young patients. The materials for the study were original articles and review papers published in the scientometric databases: PubMed, Google Scholar and eLibrary over the past 20 years. It is shown that the interest of the scientific community in body composition research has been steadily increasing over the past decades. Each successive year the total number of publications on body composition increases by an average of 24% relative to the previous year. According to our analysis of the results of a survey of medical students in Russia, body mass index is associated with the degree of urbanization and has geographical features: an increase in the proportion of students with a low body mass index was noted as the population of the city grew and it shifted in the direction from the eastern regions of the Russian Federation to the western. The proportion of students with a normal BMI decreases as the population of the city in which the medical school is located grows.
机体的组分组成是形态构成的一个方面，反映了机体内代谢过程的状态，可以作为各种病理状况发展的一种预测指标。体质指数的测定是研究人员最容易获得和最广泛使用的方法之一，它保证了不同作者所得结果的可比性。本研究的目的是整理和比较国内外作者关于年轻患者体重指数的文献资料。这项研究的材料是在科学计量数据库中发表的原创文章和评论论文:PubMed, Google Scholar和图书馆在过去的20年里。研究表明，在过去的几十年里，科学界对人体成分研究的兴趣一直在稳步增长。有关身体成分的刊物总数，每年均较前一年平均增加24%。根据我们对俄罗斯医科学生调查结果的分析，身体质量指数与城市化程度有关，并具有地理特征:随着城市人口的增长，身体质量指数较低的学生比例有所增加，并从俄罗斯联邦东部地区向西部地区转移。BMI正常的学生比例随着医学院所在城市人口的增加而减少。

Smoking is an important social problem that greatly threatens the health of the population. The purpose of the study is to study the effect of smoking on the hepatobiliary system. Material and methods. We used 46 outbred white male rats. Control group - intact animals (n=10). Experimental rats: 1-animals were in an atmosphere of tobacco smoke for 7 days (n=12), 2-14 days (n=12), 3-for 21 days (n=12). Results. The greatest changes in the liver were noted in the third group - small foci of necrosis were detected, around which a perifocal inflammatory reaction occurred. There were signs of hydropic dystrophy and the presence of acidophilic lumps around the nuclei, thrombotic masses in the vessels. Signs of capillaryization of sinusoids were revealed. In all groups, the number of cells up to 10 m in diameter significantly increased. In animals of the 1st group in the central zones there was a tendency to increase the percentage of cells with a diameter of up to 10-20 microns, in the 2nd group it increased 3 times in the central and 2.6 times in the peripheral zones, and in the 3rd group - 3.4 times and in peripheral zones - 2.8 times (p0.001). There was a decrease in the number of cells with a diameter of up to 20-30 microns (%) in group 1, in group 2 in the central zones - 1.9 times, in peripheral - 1.5 times, in group 3 - 2.7 times, in peripheral 2 times (p0.001). The number of cells with a diameter of more than 30 microns has changed, the greatest changes were noted in the peripheral zones: in group 1.2 - a decrease of 2.7 times, in group 3 - 2.9 times. Conclusions. Under tobacco smoke intoxication in rats, dystrophic and necrobiotic changes occurred in the liver, a decrease in the number of binuclear cells, a decrease in the number of normal hepatocytes with a diameter of 2030 m, and an increase in the percentage of cells with a diameter of up to 10 m and 1020 m.

Objective to estimate the efficiency of interdisciplinary approach to informative analysis of morphological constitution in young males and females in modern urboecological studies. Material and methods. The sample of modern Moscow students-psychologists aged 18-20 years, 95 males and 150 females, is used to accomplish the complex study of the constitutional status including three systems of parameters morphological (somatic: skeletal dimensions, girths, skinfolds), psychological (number of psychological tests to estimate personal anxiety, autonomic ballance, self-regulation, "Prognosis"), physiological (EEG: power and coherence in different bands and cuts) - by means of factor analysis. Results and discussion. First six constant and objective factors in the structure of total constitution of young males and females are under discussion: factor of longitudinal skeletal development, factor of transversal body development (adiposity first of all), factor of covariation of the parameters of the psychological system, factor of genetically determined physiological tone (EEG power), factors of function of the individual life experience, mediated by environment intrahemispheric and interhemispheric coherencies. Results of factor analysis are similar to both sexes with small difference, which reflects fact of more dynamic role of adipose tissue in female organism. In total 6 factors describe about 70 % variability of different systems of parameters. Conclusions. The autonomy of different systems of traits is shown, which is the base of integrity and plasticity of the organism. Such interdisciplinary studies provide the comparative integrative characteristics of morphofunctional status of various modern ethnic/territorial groups, specify the mechanisms of adaptation to concentrated anthropogenic environment, give the correct estimation of the adaptive potential of the organism in the conditions of anthropogenic pressure of high level, describe the morphophysiological base of patterns of behavior.

This article investigates the semantic polyfunctionality of affixes, i.e. their ability to serve a variety of distinct semantic functions. Based on the analysis of a sample of 3,091 deverbal nouns ending with 46 different suffixes in French, the study examines the diversity of semantic functions realized by deverbal suffixes, the distribution of these functions across suffixes and the relationships that may exist between different functions. It appears that polyfunctionality is widespread among French deverbal suffixes and involves a large number of semantic functions, with highly variable realization frequency. Several fundamental aspects of affix polyfunctionality are further highlighted. A probabilistic analysis shows that polyfunctionality can be driven by non-arbitrary semantic associations between functions. A hierarchy of functions can also be postulated depending on whether they can be instantiated by monosemous or only polysemous derivatives. In addition, polyfunctionality appears to be inseparable from rivalry relationships and to determine the degree of rivalry between affixes. Overall, the study illustrates that affix polyfunctionality is governed by systematic organizing principles whose ramifications touch on lexical ambiguity and morphological competition.

Objective to study the quantitative parameters of the bone component of the body in women of different age groups, taking into account body types. Material and methods. The physical status of 580 female Kyrgyz women was studied, which were ranked into three age groups: the youth period (16-20 years) - 210 girls, the 1st period of adulthood (21-35 years) - 186 women and the 2nd period of adulthood (36-55 years) - 184 women. Somatotyping was carried out according to the scheme of I. B. Galant - B. A. Nikityuk - V. P. Chitetsov (1983), in the presence of their informed consent. The content of the bone component was determined by J. Matiegka (1921). Results. Among the studied women, the leptosomal group of constitutions was 20%, mesosomal 32%, megalosomal 33% and indeterminate-15%. In comparison with the absolute content of bone component in girls of leptosomal Constitution, it in girls of mesosomal group almost does not change, megalosomal group increases 1.2 times (p0.05), uncertain Constitution 1.1 times more (p0.05). Compared with the percentage of the bone component of the body in women girls leptosomal Constitution, the value of this indicator in girls mesosomal group is less than 1.2 times (p0.05), megalosomal-1.3 times (p0.05), indeterminate Constitution-1.5 times (p0.05). In women of the 1st period of Mature age of the leptosomal Constitution, this indicator, compared with its value in women of mesosomal, megalosomal and indeterminate groups, is 1.4 times less (p0.05). In women of the 2nd period of mature age of leptosomal Constitution, this parameter, compared with its value in women of the mesosomal group is less than 1.4 times (p0.05), megalosomal group 1.5 times (p0.05), uncertain Constitution 1.6 times (p0.05). Conclusions. The absolute severity of the bone component of the body has minimal values in girls and women of Mature age with asthenic thin-boned somatotype (6,0 7,1 kg), the maximum-with euriplastic somatotype (6,6-9,2 kg). In women of the 2nd period of adulthood, compared with girls, the value of this indicator in representatives of all somatotypes decreases (1.1-1.2 times).

The physical status of 580 female Kyrgyz women was studied, which were ranked into three age groups: the youth period (16-20 years) - 210 girls, the 1st period of adulthood (21-35 years) - 186 women and the 2nd period of adulthood (36-55 years) - 184 women. Somatotyping was carried out according to the scheme of I. B. Galant - B. A. Nikityuk - V. P. Chitetsov (1983), in the presence of their informed consent. The content of the bone component was determined by J. Matiegka (1921). \u0000Results. Among the studied women, the leptosomal group of constitutions was 20%, mesosomal 32%, megalosomal 33% and indeterminate-15%. In comparison with the absolute content of bone component in girls of leptosomal Constitution, it in girls of mesosomal group almost does not change, megalosomal group increases 1.2 times (p0.05), uncertain Constitution 1.1 times more (p0.05). Compared with the percentage of the bone component of the body in women girls leptosomal Constitution, the value of this indicator in girls mesosomal group is less than 1.2 times (p0.05), megalosomal-1.3 times (p0.05), indeterminate Constitution-1.5 times (p0.05). In women of the 1st period of Mature age of the leptosomal Constitution, this indicator, compared with its value in women of mesosomal, megalosomal and indeterminate groups, is 1.4 times less (p0.05). In women of the 2nd period of mature age of leptosomal Constitution, this parameter, compared with its value in women of the mesosomal group is less than 1.4 times (p0.05), megalosomal group 1.5 times (p0.05), uncertain Constitution 1.6 times (p0.05). \u0000Conclusions. The absolute severity of the bone component of the body has minimal values in girls and women of Mature age with asthenic thin-boned somatotype (6,0 7,1 kg), the maximum-with euriplastic somatotype (6,6-9,2 kg). In women of the 2nd period of adulthood, compared with girls, the value of this indicator in representatives of all somatotypes decreases (1.1-1.2 times).","PeriodicalId":74228,"journal":{"name":"Morphology (Dordrecht, Netherlands)","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87131281","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}

Objective - to study the three-dimensional structure of Mauthner neurons in goldfish and the ultrastructure of their afferent synapses under the influence of L-dopa and the toxic fragment of 25-35 beta-amyloid.Materials and methods. The study was performed on Mauthner neurons of the goldfish fry (n=12) by the methods of light and electron microscopy. The identification of Mauthner's neurons and the reconstruction of their integral structure, the determination of the volume of the soma, ventral and lateral dendrites and the study of the structure of afferent synapses were carried out using serial sections 3 m thick.Results. The use of L-dopa stabilizes the size of the soma and ventral dendrites. A decrease in the volume of the lateral dendrite is accompanied either by an increase in the volume of its branches under the action of beta-amyloid, then L-dopa, or an increase in the volume of medial dendrites under the action of L-dopa, then beta-amyloid. Pathological changes in the ultrastructure of neurons and afferent synapses were not found, but signs of early amyloidosis were revealed.Conclusions. The use of L-dopa slows down the degeneration of Mauthner's neurons. It has been suggested that the resistance of whole neurons to the neurotoxic action of beta-amyloid is due to the mechanism of structural homeostasis aimed at compensatory restoration of the morphological organization of neurons.
