The aim of this study was to quantify the level of methylation of the MIR-143 gene in the tumor tissue of patients with diffuse large B-cell lymphoma (DLBCL). Material and methods. The study included 81 tumor samples of DLBCL (26 of germinal and 55 of non-germinal origin) and 11 biopsies of reactive lymph nodes. To quantify the methylation of the MIR-143 gene, the method of direct bisulfite sequencing by Sanger was used with the calculation of the average level of methylation of the analyzed CpG-sites. Results. The average level of MIR-143 methylation in tumor samples was significantly lower than the values in reactive lymph nodes (64.43 ± 19.92 и 76.27 ± 4.92 %, respectively, p = 0.049), did not depend on the immunohistochemical subtype of the tumor and showed a greater spread of values. In the lymphoma samples, there was predominant hypomethylation of one of the four analyzed CpG-dinucleotides within the boundaries of the analyzed fragment. Conclusion. The data on a change in the pattern of the MIR-143 gene methylation in the tumor tissue of DLBCL were obtained. To establish the role of microRNA in the pathogenesis of DLBCL further studies aimed at clarifying the mechanisms of epigenetic regulation of MIR-143 expression in lymphoma cells and identification of this microRNA targets are required.","PeriodicalId":33781,"journal":{"name":"Sibirskii nauchnyi meditsinskii zhurnal","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135871290","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}

In the field of epigenetics of special interest is the detection of DNA hypermethylation, which can serve as a PCa biomarker, since it is common to find and may induce a stable appropriate gene silencing, leading to significant cell changes. Aim of the study was to analyze the relationship between methylation of the APC, GSTP1 and RASSF1A genes and total PSA and prostate health index (PHI) in PCa. Material and methods. The present study included 54 patients with suspicion of PCa, up to 75-years old, who had an initial total PSA level from 2.5 to 10 ng/ml. To calculate PHI value the concentrations of total PSA, free PSA and pre-mature form of PSA ([–2]proPSA) in blood serum were measured by chemiluminescence immunoassay. Results and discussion. The study has revealed the statistically significant correlation between the degree of methylation in blood plasma samples and biopsy material of only the GSTP1 gene and PSA-associated markers. We found an increase of parameters contingency as Gleason score increased. Conclusions. As a result of this work, statistically significant direct correlations were identified between changes in methylation patterns of the promoter region of the GSTP1 gene and PHI, which allows us to consider them as potential candidates for inclusion in a diagnostic panel for more effective early detection of prostate cancer.","PeriodicalId":33781,"journal":{"name":"Sibirskii nauchnyi meditsinskii zhurnal","volume":"150 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135870881","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 evaluate some indicators of nutritional security of children with a restrictive type of nutrition and living in the territory of a long-term military conflict in the Donbass. Material and methods. 80 school-age children following restrictive diets were examined. All patients were divided into two groups: 40 children following a dairy-free diet (group 1), 40 children on a vegetarian type of diet (group 2). The control group consisted of 30 children who adhere to the traditional type of diet. Calcium, ferritin, vitamin B12 and zinc content in blood serum were studied in all children, living in Donbass. Results. In group 1 deficiency of calcium was found in 60.0 %, of zinc – in 32.5 %, of vitamin B12 – in 15.0 %, a decrease in ferritin content – in 22.5 %. In group 2 level of ferritin was declined in 55.0%, zinc deficiency was detected in 37.5 %, vitamin B12 deficiency – in 30.0 %, calcium deficiency – in 10.0 %. Conclusions. For children on a long-term dairy-free diet, calcium and zinc deficiency is characteristic, as well as a decrease in tissue iron reserves. Children who observe lactovegetarianism are characterized by a deficiency of zinc and vitamin B12, as well as a decrease in the concentration of ferritin in the blood serum. Children living in the Donbass in the conditions of a long military conflict and adhering to restrictive types of nutrition can be considered as a risk group for the development of deficient conditions.

In order to establish whether these effects are mediated or associated, among other things, with the direct effect of TS-13 on the organs and tissues of animals, in this work, the concentration of TS-13 in rat blood plasma and brain after intragastric administration was determined. Material and methods . After a single intragastric administration of a solution of TS-13 at a dose of 100 mg/kg, biomaterial (blood, brain) was taken for 24 h in male Sprague Dawley stock rats (n = 57). To measure the concentration of a substance in samples, a bioanalytical method was developed and validated using high-performance liquid chromatography with UV detection. Results and discussion . The method of quantitative determination was developed by us for the first time and validated before the study. It has been established that the calculated values of the calibration samples meet the acceptance criteria (have the required accuracy and precision) in the concentration range from 0.05 to 6 µg/ml, R=0.9998. The results of determining TS-13 concentration in rat blood plasma and brain showed that after a single administration per os, the compound enters the blood, where it is detected for 15 h (mean retention time 7.94 h, half-life 7.59 h, elimination constant 0.13 h-1, total clearance 40.1 l/(kg × h)), and also penetrates the blood-brain barrier, quickly entering the brain (maximum concentration is reached after 1 h). The compound has a low affinity for brain tissue (tissue availability 0.32), and therefore its concentration does not reach high values, however, a slow excretion of the substance is observed - the average retention time is 6.56 h, the half-life is 6.43 h, the elimination constant 0.11 h-1. Conclusions. After a single intragastric administration to rats, TS-13 enters the blood, where at least part of it is detected unchanged after 30 minutes, reaching maximum values after 1 hour. Similar kinetics of the substance is characteristic of the brain, where it is found in smaller amounts. Thus, as a result of the study, it was shown that TS-13 penetrates the blood-brain barrier and is able to directly affect brain structures, which, however, does not negate the possibility of an indirect effect mediated by the ability to change the activity of intra- and intercellular signaling systems.","PeriodicalId":33781,"journal":{"name":"Sibirskii nauchnyi meditsinskii zhurnal","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136069377","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. 174 people (87 men and 87 women) aged from 45 to 69 were examined. The study participants were randomly selected. Alcohol consumption was assessed using the AUDIT test. The content of surfactant proteins SP-A and SP-D in blood serum was determined by enzyme immunoassay using standard ELISA test sets. Statistical analysis was performed using parametric and nonparametric methods of descriptive statistics, correlation analysis was performed using Spearman criterion, and multivariate analysis was performed using binary logistic regression. ROC analysis was used to evaluate the diagnostic significance of the variables and to determine sensitivity and specificity. The critical level of significance for the null hypothesis (p) was accepted to be 0.05 in all statistical analysis procedures. Results. A typical single dose of alcohol consumed of 7–9 alcohol units (TSDAC) was inversely associated with SP-A content (r = –0.154, p = 0.043) in a general sample of men and women aged 45–59 years in Novosibirsk. By means of ROC analysis, SP-A was found to be a marker (area under the ROC curve equals 71.2 %) of alcohol intake in TSDAC. With a SP-A level not more than 921 pg/ml, its sensitivity to the determination of alcohol consumption in TSDAC is 68.7 %, the specificity is 87.5 %. Regression analysis showed that the variable “TSDAC” directly affects the presence of SP-A in a concentration not preceding 921 pg/ml (Exp (B) = 13.0; 95 % CI = 1.5; 111.0, p = 0.019) regardless of age and sex. In the general sample of men and women in Novosibirsk aged 45–69 years, as well as in men, inverse associations of Sp-D content with the presence of &gt;0 points were found in the answer to the AUDIT test question “How often during the last year have you not done something that was expected of you?”. It was determined that women had a higher level of SP-A in the blood than men. Perhaps this is due to the fact that women smoked less often than men (10.3 and 23.0 %, respectively, p = 0.020). So, it was established that a high TSDAC is an independent factor directly influencing the presence of SP-A level in the blood not exceeding 921 pg/ml for men and women aged 45–69 years in Novosibirsk.","PeriodicalId":33781,"journal":{"name":"Sibirskii nauchnyi meditsinskii zhurnal","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136068768","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}

The aim of this study was to study the effect of TS-13, a synthetic phenolic antioxidant and an activator of the antioxidant-responsive element redox-sensitive signaling system Keap1/ Nrf2/ARE, on the functional parameters of an isolated rat heart after a course of doxorubicin administration. Material and methods. Male Wistar rats (n = 24) were divided into three groups: control (n = 10), doxorubicin group (n = 7) (3 weekly intraperitoneal injections of doxorubicin solution at a cumulative dose of 15 mg/kg) and doxorubicin + TS-13 (n = 7) (administration of doxorubicin according to a similar scheme, TS-13 solution with drinking water). On the 21st day after the start of the experiment, the cardioprotective effect of TS-13 was assessed on the ex vivo model of perfusion of the heart isolated according to Langendorff. Coronary flow, heart rate (HR), pressure in the left ventricle (myocardial contractility) were recorded as parameters of myocardial functional activity; the integral indicator of myocardial contractility (working capacity) was calculated as the product of HR and pressure in the left ventricle. Results and discussion. The general toxic effect of doxorubicin was manifested in a significant decrease in rat body weight (by 21 %), the administration of TS-13 reduced the cachectic effect of the cytostatic. Doxorubicin worsened heart work by all studied parameters (coronary flow, HR, myocardial contractility and integral index of contractility); the effect persisted throughout the entire perfusion period (40 min). Animals treated with intraperitoneal injections of doxorubicin and TS-13 per os lost weight to a lesser extent, the functional activity of isolated hearts improved significantly – coronary flow, pressure in the left ventricle, and working capacity increased. Conclusions. Since, as we have shown earlier, TS-13 administration not only does not cancel, but even potentiates the antitumor activity of doxorubicin, the results obtained indicate the promise of using TS-13 as an adjuvant therapy for malignant neoplasms, enhancing the antitumor effect of the cytostatic and leveling its side effects, including cardiotoxicity.","PeriodicalId":33781,"journal":{"name":"Sibirskii nauchnyi meditsinskii zhurnal","volume":"9 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136135039","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}

In case of conservative therapy ineffectiveness, chronic instability of the ankle joint develops, which can significantly reduce the patient’s quality of life, in this situation, the surgical treatment becomes uncontested. The choice of the surgical intervention method is determined not only by the nature of the injury, but also by the ligamentous-tendon apparatus condition. In addition, to a large extent, surgical tactics is chosen based on the preferences of the individual surgeon. The article describes the anatomical and physiological features and risk factors that determine the occurrence of acute the ankle joint instability and its transition to a chronic state, as well as the main methods of the anterior talofibular ligament plastic surgery and their common modifications. Special attention is paid to the effectiveness evaluating methods of surgical techniques on cadaveric ligamentous material. An analysis of the literature shows that the study of the issue remains insufficient. New clinical data obtaining will increase the effectiveness of the surgical technique for ankle instability treating and significantly improve the quality of life of patients.","PeriodicalId":33781,"journal":{"name":"Sibirskii nauchnyi meditsinskii zhurnal","volume":"9 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136312218","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}
