Speech Conflict in Family Communication

The study was performed in line with the actual scientific areas of language conflictology and linguistic axiology. The article is devoted to the linguistic description of conflict situations in family communication by the material of the film “Inadequate people” (directed by Roman Karimov). The relevance of the study is due to the need to study communication in small social groups (in particular, in the family), as there is a high level of emotionality and intensity of communication, and it often becomes a conflictogenic factor. The text fragments representing speech conflicts between a teenager and adult relatives are analyzed. The markers of destructive communication and speech aggression in the communicative behaviour of adults (negatively charged language means and non-cooperative speech-behavioral tactics of condemnation, threat, coercion, etc.) and adolescents (high tone, insults, rude demand, disharmonizing strategy of discredit, tactics of “rudeness” and other). Special attention is paid to implicit speech aggression, which is embodied in irony, sarcasm, indirect issues. It is noted that using such techniques, the communicant expresses a negative or critical attitude towards the addressee. It is indicated that the intergenerational conflict is expressed in the deformation of interpersonal communication, in the failure of mechanisms of understanding between parents and children, in disagreements concerning moral and value orientations

Quality of life at machine operators of agriculture

The purpose this research was to investigate the quality of life machine operators of agriculture, depending on the status of the age and length of service in the profession. To assess the quality of life was used widely used international Russian-language health a validated questionnaire SF-36. Studies have been conducted practically healthy quality of life (based on the results of periodic medical examinations) machine operators of agriculture Saratov region (102 people) aged 30 to 59 years of experience in the profession from 3 to 35 years. Average values of an indicator for age groups 2 and 3 made "the general health", respectively, 95,2 and 78,7 % from level characteristic for younger age group. Intergroup distinction was noted between average sizes of this indicator at persons at the age of 30-39 years and 50-59 years, and also 40-49 summer machine operators and workers of advanced age (50-59 years). 1t is established that with increase in calendar age at machine operators of agriculture statistically significant decrease in values of indicators of quality of life to scales the general health, physical functioning, physical and role functioning and viability. With increase in length of service at machine operators decrease in values of indicators of physical functioning and role physical functioning. A statistically significant weak negative correlation between the level of quality of life, age (r = -0,39) and professional experience (r = -0,31). 1n this case, the highest correlation between the age of the examined patients and quality of life was typical of the general health scale (r = -0,37), physical functioning (r = -0,41), and role physical functioning (r = -0,34). Professional experience correlated with the level of physical functioning (r = -0,30) and role^hysical functioning (r = -0,32), has practically no effect on the subjective assessment of general health (r = -0,22). Results of researches allow recommending questionnaire SF-36 use when forming individual and group improving programs for machine operators of agricultural production

EPR study of hydrocarbon generation potential of organic-rich domanik rocks

© Kazan Federal University (KFU). The objects of investigation were samples of domanik formation rocks of Berezovskaya area of Romashkinskoye oil field. Content of Mn 2+ , SO 3 − , SO 2 − ions, vanadyl-ions and free radicals has been estimated with the X-band (9.43 GHz) electron paramagnetic resonance (EPR) spectroscopy. Composition of rock and extracted from it bitumen has been studied with methods of thermal analysis, X-ray-structural analysis and gas chromatography. Significant differences in mineralogical composition and content of organic matter were revealed in samples taken from adjacent intervals. Pyrolytic experiments have been conducted to simulate kerogen maturation and petroleum generation. The increasing number of free radicals was registered in all samples after pyrolysis in a hydrogen atmosphere at 350°C. A new organic free radical C350 was registered after pyrolysis. It is suggested that domanik source rocks have not fully realized their hydrocarbon generation potential

Pyrrolylquinoxaline-2-one derivative as a potent therapeutic factor for brain trauma rehabilitation

Traumatic brain injury (TBI) often causes massive brain cell death accompanied by the accumulation of toxic factors in interstitial and cerebrospinal fluids. The persistence of the damaged brain area is not transient and may occur within days and weeks. Chaperone Hsp70 is known for its cytoprotective and antiapoptotic activity, and thus, a therapeutic approach based on chemically induced Hsp70 expression may become a promising approach to lower post-traumatic complications. To simulate the processes of secondary damage, we used an animal model of TBI and a cell model based on the cultivation of target cells in the presence of cerebrospinal fluid (CSF) from injured rats. Here we present a novel low molecular weight substance, PQ-29, which induces the synthesis of Hsp70 and empowers the resistance of rat C6 glioma cells to the cytotoxic effect of rat cerebrospinal fluid taken from rats subjected to TBI. In an animal model of TBI, PQ-29 elevated the Hsp70 level in brain cells and significantly slowed the process of the apoptosis in acceptor cells in response to cerebrospinal fluid action. The compound was also shown to rescue the motor function of traumatized rats, thus proving its potential application in rehabilitation therapy after TBI. © 2020 by the authors.

Blood biomarkers and Ki-67 proliferation marker in breast cancer

Metastasis is the leading cause of death in patients with breast cancer (BC). It is known that the lesion of regional lymph nodes by tumor cells is more common in tumors with higher proliferative activity. Moreover, there is literature evidence on effects of cytokines and proteins upon the migration potential of the tumor. The aim of our work was to study the correlation between the concentrations of cytokines, proteins, and expression of Ki-67 proliferation marker in breast cancer with histology of non-specific invasive carcinoma.On the basis of pathological findings, 16 patients had metastases in regional lymph nodes (group I), and 18 patients had no detectable metastases (group II). Solid-phase enzyme immunoassay was used to determine concentrations of 14 cytokines in the supernatants of immunocompetent blood cells, i.e., IL-2, IL-6, IL-8, IL-10, IL-17, IL-18, IL-1β, IL-1ra, TNFα, IFNγ, G-CSF, GM-CSF, VEGF and MCP-1, and concentrations of 6 proteins were determined in blood serum: estrogen and progesterone receptors, cadherin-E (CDH1), plasminogen activator type 1 (PAI-1), mucin 1 (MUC1), heat shock protein 90αA1 (HSP90αA1). Immunohistochemical study of Ki-67 expression was performed in paraffin sections of tumors using monoclonal antibodies.The study showed that Ki-67 expression in tumor tissues and blood concentrations of IL-6, IL-8, IL-1β and TNFα were higher in group I patients. On the contrary, blood concentrations of CDH1 and PAI-1 were higher in group II patients. It was found that Ki-67 showed both inverse correlations with CDH1 and PAI1, and direct correlations with IL-8 and TNFα. CDH1 had a direct correlation with PAI1, and inverse correlations with IL-6, IL-1β and TNFα. The studied cytokines showed direct correlations with each other. The analysis of ROC curves showed good quality and optimal values of the cut-off points for Ki-67 expression, cytokine and protein concentrations, thus allowing best prediction for detectable lymphatic metastasis.On the basis of these results, a quotient was proposed, which represents a ratio of CDH1 contents to the sum of IL-1β and TNFα concentrations in blood samples, which can help identification of the patients with breast cancer at risk for lymphatic metastasis

Investigation of the Sorption Properties of Ore Materials for the Removal of Sulfur Dioxide from Exhaust Flue Gases of Power Plants

The prospects of using a natural material – ferromanganese nodules (FMN) from the Gulf of Finland – as the SO2 adsorbent are discussed. The starting material was studied as pellets and powder using X-ray fluorescence spectroscopy, XRD, BET, and mechanical strength analysis; dependences of physicochemical parameters of the material on heat treatment at 100-1000 ºC were found. FMN samples were tested in the process of SO2 sorption. The sorptive capacity of FMN samples for SO2 was found to increase with humidity of adsorbents; FMN samples with a humidity above 40% were shown to be promising for the removal of sulfur dioxide from gase

CYTOKINE-PRODUCING RESOURCE OF IMMUNOCOMPETENT BLOOD CELLS IN BREAST TUMORS AND PRECANCEROUS CHANGES OF MAMMARY GLAND

At present, only ductal carcinoma in situ is included into the group of precancerous lesions of mammary ducts, according to International Agency for the Study of Cancer. However, based on recent publications, in addition to ductal carcinoma in situ, sclerosing adenosis, intraductal proliferative lesions and radial scar may be also attributed to precancerous changes. A variety of both benign and malignant events in mammary gland, the features of neoplastic growth and age of the patients require new approaches to study of carcinogenic events in mammary gland. As based on the known role of cytokines in genesis of malignancies, the aim of the study was to evaluate the cytokine-producing resource of immunocompetent blood cells in malignant, benign and precancerous mammary disorders. To assess the cytokine-producing resource of immunocompetent blood cells in the patients, we studied quantitative effects of polyclonal activators upon production of cytokines by immunocompetent blood cells of patients with invasive ductal cancer representing a histological type of adenocarcinoma (group I), and patients with non-malignant breast neoplasias (group II). At subsequent step, the patients with non-malignant neoplasms of the breast were divided into a subgroup of patients with only fibroadenoma and mastopathy (group III), and a group which included patients with precancerous diseases, i.e., sclerosing adenosis and interductal proliferates (group IV). Concentrations of IL-2, IL-6, IL-8, IL-10, IL-17, IL-18, IL-1β, IL-1ra, TNFα, IFNγ, G-CSF, GM-CSF, VEGF, and MCP-1 were determined by solid-phase enzyme immunoassay. When comparing groups I and II, we revealed higher influence of polyclonal activators upon production of G-CSF and GM-CSF in patients with invasive ductal cancer. When comparing the influence of polyclonal activation for cytokine production in patients of I and III groups, higher values were registered in patients with invasive ductal cancer (production of IL-2, G-CSF, and GM-CSF), and in patients with fibroadenoma and mastopathy (IL-18, and TNFαproduction). When comparing patients of groups I and IV, higher indexes of the polyclonal activator effects were found only for IL-1ra, G-CSF, and VEGF production in invasive ductal cancer. When comparing the indexes of polyclonal activator influence upon cytokine production of groups III and IV, higher values were obtained in patients with benign changes for the following cytokines: IL-8, IL-18, IL-1β, IL-1ra and TNFα, in contrast to patients with sclerosing adenosis and proliferates. The lower indexes of polyclonal activating effects upon the production of a number of cytokines in patients with precancerous changes, as compared to patients with malignant and benign breast tumors, do not indicate a decreased functional activity of immunocompetent blood cells. However, those may be due to high level of spontaneous cytokine production in sclerosing adenosis and interductal proliferates
