The current paradigm suggests a key role of macrophages in inflammation in COPD. Macrophages are known to be heterogeneous in their functions. This heterogeneity is determined by their immunometabolic profile and also by peculiarities of lipid homeostasis of cells. Aim . To analyze the role of the ABCA1 transporter, a member of the ABC A subfamily, in the pathogenesis of COPD. The expression of ABCA1 in lung tissues is on the second place after the liver, which shows the important role of the carrier and of lipid homeostasis in the function of lungs. Analysis of the literature shows that participation of the transporter in inflammation consists in regulation of the content of cholesterol in the «lipid rafts» of the membranes, in phagocytosis and apoptosis. Conclusion . Through regulation of the process of reverse transport of cholesterol in macrophages of lungs, ABCA1 can change their inflammatory response, which makes a significant contribution to the pathogenesis of COPD.","PeriodicalId":13184,"journal":{"name":"I.P.Pavlov Russian Medical Biological Herald","volume":"64 1","pages":"360-370"},"PeriodicalIF":0.0,"publicationDate":"2020-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74163496","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}

Determination of the actual spectrum of pathogenic microorganisms to which medical workers of mobile teams of emergency medical care (EMC) are exposed, and scientific justification of the class of the working conditions of this professional group in terms of the biological factor. Materials and Methods. Data of the electronic journal of the automated «Ambulance Service» control system for infectious patients, and records of the register for infectious diseases among workers of the municipal emergency medical care station of Ryazan (300 medical assistants, 64 doctors) for 2016-2019 were used. Results. The average amount of calls to patients with infectious pathology in 2016-2019 made 2178.5±221.3 per year. Most emergency calls were for intestinal infections, common cases were varicella, erysipelas, viral hepatites, tuberculosis infection, herpes zoster. The main load in servicing these calls fell on linear (from 63.7 to 77.4%) and pediatric (from 24.8 to 35.1%) teams; calls of resuscitation teams to patients of such profile were sporadic. The level of infectious morbidity of doctors made 0.78 cases per 100 doctors which is 1.2-fold higher than the level of medical assistants (t=3.79; р=0.0003). Conclusion. The confirmed cases of diseases of the studied group of workers resulting from professional contacts with sources of infections of Group III pathogenicity permits to refer the working conditions of medical workers of mobile teams of emergency medical care stations to hazard Class II. However, a high probability for professional contact with high pathogenicity strains of group A influenza, HIV-1 and HIV-2, hepatitis C, D, E viruses belonging to Group II pathogenicity, and existence of the evident contacts with SARS-CoV-2, permit to raise the class of the working conditions to hazard Class III.","PeriodicalId":13184,"journal":{"name":"I.P.Pavlov Russian Medical Biological Herald","volume":"2 1","pages":"283-289"},"PeriodicalIF":0.0,"publicationDate":"2020-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83432839","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}

Generalization of literature and proprietary data on genetic-physiological and evolutionary processes occurring in human populations in environmentally neglected industrial cities. In the review information is given about damage to the genetic apparatus of cells of a human organism under influence of unfavorable environmental factors and disadaptations of different genesis. To denote the totality of alterations induced by the given exposure, a new term is introduced – ‘genetics of disadaptations’. The information of mutagenic factors of the environment of industrial cities associated with growth of oncological diseases and of malformations resulting from chromosomal aberrations in cells is generalized. The problem of genetic burden of human populations in environmentally neglected territories and of the influence of disadaptive factors on this process is discussed. Information of the ecological situation and morbidity of the population in Cherepovets industrial city is given. A role of disadaptations in genetic-evolutionary processes occurring in human populations is shown. The cause of different manifestations of disadaptation in the population is stated to be divergence of traits. A hypothesis is proposed and evidences are given in favor of the existence of natural selection for a disadaptive trait in human populations. It is suggested that being accumulated in a human organism, disadaptive disorders may be transmitted to the next generations reducing vital ability of organisms and inducing different diseases.

Materials and Methods . 106 Cases of colorectal cancer in patients who were on treatment in Ryazan Clinical Oncological Dispensary (Ryazan) were analyzed. Genotyping in all patients was performed using the method of isolation of DNA from leukocytes of venous blood with subsequent polymerase chain reaction (PCR) with electrophoretic detection of the result. Results. No interrelation between the age of patients and polymorphism of any studied gene was recorded at the moment of verification of the diagnosis (р>0.05). Statistically significant relationship was identified between polymorphism of TNF ( G308A ) gene and the stage of cancer: its homozygous major genotype G/G more commonly occurred in the group of patients with III-IV stage (р=0.047). In the presence of allele of G/G TNF ( G308A ) gene together with homozygous mutant allele of MMP1 (1607 1G/2G ) gene , a direct relationship with increase in the number of patients diagnosed with III-IV stage was noted. This combination of two polymorphisms showed a statistically significant difference in the studied groups (р=0.025). In 8 out of 10 patients with IV stage, the presence of G/G polymorphism in VEGF ( C 654 G ) gene was noted. This mutant homozygous variant was much more rare in patents with I (37.5%), II (40%) or III stages (37.5%) (р=0.0147). Conclusions. The studied genes do not influence the age of manifestation of colorectal cancer and occur at the same frequency in patients of both genders irrespective of the age group. Localization and the extent of differentiation of the tumor do not depend on polymorphism of the studied genes either. The presence of G/A polymorphism of TNF (G308A) gene should be considered a favorable criterion associated with lower aggressiveness of the tumor (р<0.05), whereas identification of the major G/G genotype especially in combination with homozygous mutant allele of MMP1 (1607 1G/2G) gene is an unfavorable factor (р<0.05). The presence of G/G mutant genotype of VEGF ( C654 G) gene may directly correlate with rapid progression of tumor and with active metastatic spreading (р<0.05).","PeriodicalId":13184,"journal":{"name":"I.P.Pavlov Russian Medical Biological Herald","volume":"22 1","pages":"127-134"},"PeriodicalIF":0.0,"publicationDate":"2020-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74292057","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 a large number of modern methods for stopping parenchymal bleeding, many practi-tioners give preference to classic methods of hemostasis, including ligation of bleeding vessels in the bulk of the organ using specialized sutures. One of the most serious complications of the use of suture material is cutting of organ tissue, which leads to enhanced bleeding and expansion of the area of damage. At the moment, the tactics of choosing suture material for surgical procedures is empirical. In this context, the aim of this study was to assess the physico-mechanical properties of suture material regarding its structure, and to develop a criterion for choosing surgical sutures for surgical procedures. For the study, the liver was removed out of corpses of males of 35 to 40 years of age, after which separate sections of 7.5×7×4 cm in size were obtained from it. Then a wound 3 cm long and 2 cm deep was made. The wound was sutured with a simple interrupted suture without tightening, but with application of one simple half-node. For suturing, catgut, twisted capron and polyglycolide thread were used. Attention was paid to the maximal force applied at the moment of cutting (Fmax) and the degree of pulling the thread at the moment of cutting (Lu). The analysis of the data was based on comparison of Fmax and Lu parameters. This method permits to refuse from the empirical approach to the choice of suture material for operations on the liver, and to develop a criterion for choosing surgical sutures.","PeriodicalId":13184,"journal":{"name":"I.P.Pavlov Russian Medical Biological Herald","volume":"54 4 1","pages":"193-199"},"PeriodicalIF":0.0,"publicationDate":"2020-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76152290","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}
