Together with the known pathogens of inflammatory processes of the respiratory tract in clinical practice are often found representatives of Streptococcus and Klebsiella, previously considered commensals of the mucous membranes of the upper respiratory tract. The exchange of genetic information facilitates the transfer of virulence factors between strains not only within the species but also within the genus. In such cases, the acquisition of virulence genes by nonpathogenic species from representatives of pathogenic species contributes to the manifestation of previously not typical properties. Therefore, the aim of the research was to study the virulence of opportunistic Streptococcus spp. and Klebsiella spp. in inflammatory processes of the respiratory tract and substantiate their etiological role in the development of the disease. We studied 220 strains of Streptococcus spp. and 97 strains of Klebsiella spp., isolated from patients with inflammatory processes in the respiratory tract and from healthy individuals. Strains of Streptococcus spp. were investigated for the presence of virulence genes: sagA, lmb, fapl, ply, lytA. Strains of Klebsiella spp. were examined for the presence of virulence genes: MrkD, magA, kfu. The phenotypic marker of lmb gene expression in Streptococcus and MrkD gene in Klebsiella was the indicator of adhesion of isolated strains to buccal epithelial cells. Expression of the fapl gene was evaluated in a phenotypic biofilm formation test. In individuals with upper respiratory tract inflammation, the most common types of strepto -cocci were: S. mitis, S. anginosus, and S. oralis. Strains of these species isolated from inflammatory processes in the upper respiratory tract had 2—4 times greater adhesiveness than strains isolated from healthy individuals. Phenotypic determination of the ability to biofilm formation showed that strains of Streptococcus containing the fapl gene formed a dense biofilm in contrast to strains without the fapl gene. K. oxytoca strains isolated from people with sinusitis had mrkd, magA, and kfu virulence genes that are characteristic of K. pneumoniae strains. In phenotypic tests, it was found that the value of the adhesion index in K. oxytoca strains isolated from patients is 4 times higher than in strains of this species isolated from healthy individuals. Thus, to confirm the etiological role of an opportunistic microorganism in the development of the infectious process, it is necessary to be guided by data on the genetic and phenotypic markers of virulence of the isolated strain.

Aim. Health-related quality of life in patients with arterial hypertension (HTN) is still determined by only generic patient-reported outcome measures (PROMs), although disease-specific ones are more reliable and highly valid. Previously, we reported the results of development and item-selection process of the new Russian HTN-specific PROM. The purpose of this last stage was to confirm validity, reliability, responsiveness and sensitivity of the scale and to present its final version.

Material and methods. Analysis was done using data from a mass survey of patients with Grades 1-3 HTN (n=359, aged 25 to 91 y. o.) and healthy volunteers (n=48, aged 23 to 65 y.o), 407 returned questionnaires. We conducted two exploratory factor analyses (EFA) with the intermediate version of the PROM (80 questions, 20 of them HTN-specific). The Cattel’s scree test was used to select the optimal number of factors. After removing the items with a low factor loadings, a confirmatory factor analysis (CFA) was performed to assess the model’s fitindexes adequacy. The core indexes to be measured were SRMR, RMSEA, CFI. Finally, the PROM’s reliability (Cronbach’s α and McDonald’s ω) and criterion validity (responsiveness) were evaluated.

Results. Both EFA with oblique and varimax rotation showed 35 questions have factor loadings ≥0,5 and assigned to one of 5 factors. The basic structure of the PROM was retained for further CFA. Most of indices of fit measured met the requirements: SRMR was 0,08, RMSEA was 0,07 (90% CI (0,07-0,08)) and CFI was 0,08, which confirms the construct validity. Both Cronbach’s α and MacDonald’s ω of each of the domains were ≥0,80 and the whole scale was 0,89 confirming satisfactory reliability. Scores of the questionnaire were positively correlated with the severity of HTN (p<0,001 for Grades 1-3 HTN) and between HTN and non-HTN patients (p=0,01 and 0,04 in psychologic and social domains respectively).

Conclusion. Sequentially addressing of exploratory and confirmatory factor analyses and assessment of reliability and responsiveness allowed to form the final version of the patient-reported outcome measure for arterial hypertension. The new Russian-language questionnaire is a useful and feasible tool for routine practice and clinical trials.

Published: April 2020

Cardiac remodeling refers to factors that increase the risk of cardiovascular events in patients with hypertension (HTN). Changes in myocardial structure and function can be caused not only by hemodynamic causes, but also a number of metabolic disorders.

Aim. To analyze the associations of insulin resistance and left ventricular (LV) remodeling in a cohort of young patients with untreated uncomplicated hypertension and high normal blood pressure (BP).

Material and methods. The presented cohort cross-sectional study included 105 subjects. We analyzed clinical, demographic and anthropometric characteristics, performed a biochemical panel (creatinine, potassium, lipid profile, glucose, insulin, uric acid) with the estimation of insulin resistance scores (HOMA-IR, METs-IR, TyG), a glycosylated hemoglobin test. Urine albumin-to-creatinine ratio was determined. Office and 24-hour ambulatory BP measurement and two-dimensional speckletracking echocardiography were performed in all patients.

Results. The median age was 23 years (men — 85%); 51% of participants were overweight or obese, 39% had dyslipidemia, 21% — insulin resistance. Signs of LV remodeling were observed in 38 (40%) subjects: 32 (34%) — concentric remodeling, 5 (5%) — concentric LV hypertrophy (LVH), 1 (1%) — eccentric LVH. Defects of LV systolic global longitudinal strain (GLS) were observed in 44 (47%) young patients with HTN and preHTN. Stepwise multivariate regression analysis revealed that the TyG index was an independent predictor of LV GLS defects (b=0,38, p=0,001).

Conclusion. In a cohort of young patients with HTN and high normal blood pressure, there is a high prevalence of insulin resistance, metabolic disorders, and early signs of LV remodeling and subclinical systolic dysfunction. The TyG index, available for estimation by routine biochemical tests, is an independent factor affecting the LV GLS.

Published: April 2020

The purpose of this study is to investigate the effectiveness of a CRA-based number sense teaching program on young children’s mathematical attitude and mathematics achievement. For this study, 57 children aged 6 years old participated from three child care centers in B city, and the study was conducted from July to September 2018. The program was performed with the intervention group for a total of 19 times, three or four times per week for 30 minutes each time. No intervention was performed with the comparison group. The mathematical attitude test and the mathematical achievement test were used for the pre- and post-tests. The results from this study are as follows: First, there was no difference between the intervention group and the comparison group in the pre-test of mathematical attitudes. In the post-test, the intervention group showed significantly higher scores in the total score of the mathematical attitudes, in the scores of self-concept of mathematical ability, and in the scores of the perception of the task. There was no significant difference in the pre- and post-test for the mathematics achievement between the intervention group and the comparison group. Second, according to the analysis of the pre- and post-tests scores in the mathematical attitudes of the low number sense group, no differences were found in the total score and the scores of sub-factors. Also there was no significant difference in the pre- and post-tests for the mathematical achievement. These results imply that the number sense teaching program based on the CRA model has a positive effect on the mathematical attitudes of young children. However, this study also suggests that more intensive and longer interventions for children with low-achieving results should be provided to improve their mathematical attitude and math achievement.

Противоречивость изменений в сфере труда требует пересмотра подходов к изучению ценностно-мотивационных основ трудовой деятельности. В данной статье трудовая деятельность представлена как динамично развивающаяся система, элементами которой являются ценностно-ориентационная основа, конкретные трудовые практики в существующей социально-экономической ситуации и мотивация трудовых практик. Проводится различие ценностных диспозиций и реальной мотивации труда как реакции сотрудника на условия, которые ему предоставляет конкретное рабочее место или та профессия, в рамках которой он работает. На основе эмпирического исследования 1423  российских работников изучаются факторы формирования действующих ролевых стандартов трудовой деятельности российских работников, проводится оценка роли трудовых диспозиций и ценностей сотрудников в этих процессах, а также выявляется значимость социально-экономических условий рабочих мест и профессий.  Результаты исследования показали, что при безусловном доминировании материалистических ценностей обнаруживаются существенные профессионально-отраслевые различия в актуализации ценностей, ориентированных на личностное развитие. Было  обнаружено, что наличие ценностного приоритета «Ориентация на самореализацию и профессиональное развитие» значимо связано с позитивной нормативной моделью индивидуального трудового поведения, и в сочетании с ориентацией на «Возможность получения новых знаний, умений» отрицательно связано с негативной моделью индивидуального трудового поведения. Помимо этого, было выдвинуто предположение о благотворном влиянии содержания профессии на формирование мотивации добросовестного, высокопрофессионального труда. Среди внешних факторов решающую роль в формировании и поддержании трудовой мотивации играют конкретный коллектив и  принятые в нем нормы.

В статье рассматривается динамика организационных особенностей в «автономных» ресурсодобывающих сообществах юга России. Авторский анализ основан на результатах многолетнего полевого исследования (2012–2019 годов) с применением нескольких методик  – интервьюирования, неформальной беседы, прямого и включенного наблюдения, многоместной этнографии. В рамках концепции «автономного» сообщества и экс-полярной экономики выделяются типы социальных групп этих сообществ. На основе производственной специализации также обозначаются типы основной социальной группы «автономного» сообщества – самообеспечиваемого домохозяйства. С начала 1990-х годов усилился процесс маргинализации прибрежного рыболовства, который, в отличие от мировой практики, явился результатом аномии после развала государственной системы социально-экономического и политического регулирования. «Автономизация» стратегий жизнедеятельности и социальной структуры стала ответом локальных сообществ на аномию. Исследование показало, что наиболее развитая система социального взаимодействия в «автономных» сообществах встречается в предгорном Дагестане, обеспечивая максимальную эффективность саморегулятивным практикам посредством деятельности симбиотических структур через каналы родственных сетей и религиозных практик.

Extracellular DNA extraction from sediment using phosphate buffer and NucleoSpin Plant II Midi kit (MACHEREY NAGEL) v1
Authors: Chardon Cecile , Jacas Louis , Domaizon Isabelle
Published: April 2020

This DNA extraction protocol makes it possible to extract extracellular DNA from sediment and to work with around 4g of sediment. This protocol was adapted by INRAE - CARRTEL (Thonon les Bains, France) to work on lake sediments and perform paleolimnological analyses. The objective of the protocol is : * to desorb extracellular DNA from the mineral and organic particles, using a saturated phospahe buffer (Taberlet et al 2012, Giguet-Covex et al 2019). The desorption of DNA is obtained by mixing 1Volume of saturated phosphate buffer with 1Volume of sediment ; however, in some cases, when sediment contain high concentration of organic matter, it is recommand to increase the amount of phosphate buffer up to twice the weight of the soil/ sediment (Taberlet et al 2012). * to collect DNA extracts from several grams of sediment : many DNA extraction kits (e.g. NucleoSpin soil) largely used in sedimentary DNA research do not cope with high amount of sediments (> 1 g). Though it makes sense to analyse as much sediment as possible to be representative and avoid heterogeneity of results due to non homogenous sediments. In some studies, extracellular DNA extraction was carried out from up to 24g of sediment (Giguet-Covex et al 2019), using 20mL of phosphate buffer but only a low percentage of the obtained supernatant countaining extracellular DNA was finally fixed on membranes and used for the analysis. This was due to the fact that NucleoSpin® Soil kit (Macherey-Nagel) columns used in this study, have a binding capacity of 50µg of DNA (corresponding at a maximum of 0.5g of sediment) and a maximum volume capacity of 0.650mL. For the adated protocol we tested here, we chose to use an other extraction kit, NucleoSpin® Plant II Midi (Macherey-Nagel), where columns have a binding capacity of 200µg of DNA and a maximum volume capacity of 5mL. This choice offers the opportunity to work with several g of sediment (here 4g were tested) with the possibility to keep the total volume of supernatant (4.5 - 5mL) obtained after the desorption step.

Open reduction and K-wires fixation of medial humeral epicondyle fractures with intra-articular elbow entrapment in children
Authors: Massetti Daniele , Marinelli Mario , Coppa Valentino , Falcioni Danya , Specchia Nicola , Giampaolini Nicola , Gigante Antonio P.
Published: April 2020

Background. Medial epicondyle fracture (MEF) is a common injury of all elbow fractures in the pediatric and adolescent population and is often associated with elbow dislocation. Traditional management by cast immobilization increasingly is being replaced with early open reduction and K-wires or screws fixation. A consensus about the correct treatment of MEF is currently lacking in the medical literature.
The aim of this study was to report the clinical and radiographic outcomes and the complications of patients affected from MEF with intra-articular fragment incarceration treated by open reduction and K-wire fixation.
Materials and methods. Thirteen children (aged 813 years) with medial epicondyle fractures (MEF) with intra-articular elbow entrapment were retrospectively reviewed. All the enrolled patients were surgically treated with open reduction and k-wire fixation without exploration of ulnar nerve. Clinical outcomes were evaluated using upper limb alignment in the frontal plane, elbow range of motion (ROM), the Mayo Elbow Performance Score (MEPS) and with the Visual Analogue Scale (VAS). Radiographic outcomes and complications were also evaluated.
Results. At a mean follow-up of 24.1 months no patients showed axial deformity of the upper limb or instability of the elbow and with preserved elbow ROM. The mean MEPS was 98.8 and the mean value of the VAS score was 1. The final X-rays showed fracture healing in 11 patients while 2 (15.3%) reported asymptomatic nonunion. Six patients of 13 presented with preoperative paresthesia in the ulnar nerve field but all of them reported a complete recovery after a mean of 4.3 months. All patients returned to their sporting activities at a mean of 5.4 months after surgery. One patient (7.7%) reported a superficial surgical wound infection treated with oral antibiotic medication without further surgery. No other complication was found.
Conclusions. The results demonstrate that open reduction and K-wires fixation without exploration of ulnar nerve for MEF with intra-articular elbow entrapment treatment is a safe and effective procedure.
The Effects of Atmospheric Models on the Estimation of Infrasonic Source Functions at the Source Physics Experiment
Authors: Poppeliers Christian , Wheeler Lauren Bronwyn , Preston Leiph
Published: April 2020

We invert infrasound signals for an equivalent seismoacoustic source function using different atmospheric models to produce the necessary Green’s functions. The infrasound signals were produced by a series of underground chemical explosions as part of the Source Physics Experiment (SPE). In a previous study, we inverted the infrasound data using so-called predictive atmospheric models, which were based on historic, regional-scaled, publicly available weather observations interpolated onto a 3D grid. For the work presented here, we invert the same infrasound data, but using atmospheric models based on weather data collected in a time window that includes the approximate time of the explosion experiments, which we term postdictive models. We build two versions of the postdictive models for each SPE event: one that is based solely on the regional scaled observations, and one that is based on both regional scaled observations combined with on-site observations obtained by a weather sonde released at the time of the SPE. We then invert the observed data set three times, once for each atmospheric model type. We find that the estimated seismoacoustic source functions are relatively similar in waveform shape regardless of which atmospheric model that we used to construct the Green’s functions. However, we find that the amplitude of the estimated source functions is systematically dependent on the atmospheric model type: using the predictive atmospheric models to invert the data generally yields estimated source functions that are larger in amplitude than those estimated using the postdictive models.

Published: April 2020

In this paper, one studied the effect of pulsed laser radiation (1064 nm, 120 μs) on lignite. The method of mass spectrometry was used to analyze the formed gaseous reaction products after the exposing of coal samples to the laser radiation. The pressed out of the pre-milled coal particles tablets were used as samples. In the mass spectra of the reaction products of laser radiation of the samples, the peaks with a mass to ion charge ratio m/z = 2, 18, 44 were detected, that corresponds to the main peaks of H2, H2O, and CO2 molecules. The pattern of formation of the end products CO2, H2, H2O when heating a sample of coal by laser radiation is proposed. The energy release factor is calculated, which is defined as the ratio of the calorific value, released during combustion of the sample to the dose of energy absorbed by the sample during irradiation.
Study of the Properties of Qxide Coatings Formed on Titanium by Plasma Electrolytic Oxidation Method
Authors: Ramazanova Zh.M. , Zamalitdinova M.G.
Published: April 2020

The development of the modern industry requires to develop high-performance, environmentally friendly methods for the production of light structural material surface coatings. The use of products and structures made of titanium and its alloys with high wear resistance and corrosion resistance prevails in many industries, in particular in the aerospace industry, shipbuilding, and transport engineering. Nowadays, the application of the plasma electrolytic oxidation method, a promising metal surface treatment method, is of increasing interest. Besides this method is called microarc oxidation. The objective of this work is to study the properties of oxide coatings obtained on titanium alloys under the influence of rapid pulsed effects of the plasma electrolytic oxidation process. Oxide composite coatings were obtained in various electrolyte solutions in this work. Oxide coatings are characterized by high wear resistance. It has been established in tribological tests that the wear resistance of the coating is increased by 2–15 times compared with an uncoated sample. The friction coefficient curves obtained for coated samples show that there is no destruction of the coating to the base. The breaking-in area is marked in the curves. The friction surfaces are adjusted to each other and go to a stable friction mode. The latter results in the friction coefficient decrease and wear rate decrease.
THE GENDER REVEAL PARTY
Authors: Jack Astri
Published: April 2020

This article explores the popularization of gender reveal parties and considers what they can tell us about current societal expectations around gender, parenthood, and consumption. Gender reveal parties are events in which expectant parents reveal, or even learn, the sex of the child-to-be through a surprise display of something pink or blue, typically using innocuous means such as confetti, balloons, or a coloured cake. However, methods for revealing fetal sex have become increasingly bizarre and dangerous, involving firearms, car fires, and, in at least one case, an alligator. This article examines digital media depictions of gender reveal parties and their aftermath; discusses sexing technologies and diversity in biological sex and gender; looks critically at how capitalism and the White neoliberal state have constructed the gender reveal party as a performative event for parents-to-be; and explores the physical and affective violence done to individuals, families, and the natural environment by gender reveal parties.
Acute Pulmonary Edema After Large Molar Pregnancy Uterine Evacuation
Authors: Abbasi Hajar , Behforouz Athena
Published: April 2020

Cardiopulmonary complications have been observed after the evacuation of benign hydatidiform mole which can lead to substantial morbidity and mortality. We report a 30-years-old woman who came to our outpatient department of obstetrics and gynecology at 9 weeks gestational age with sonography which represented molar pregnancy. Evacuation of the mole was done under spinal anesthesia as an elective procedure. The patient had a complaint of dyspnea, 6 hours after evacuation. CXR showed some reticular opacity in the field of both lungs with increased Broncho vascular marking. CT angiography showed pulmonary edema with subsegmental atelectasis in the base of both lungs without any pattern of pulmonary thromboembolism. Pulmonary edema was regressed by administering frusemide and conservative management after 8 days of ICU admission. She was discharged on the 10th postoperative day in satisfactory and stable condition
Disseminated Juvenile Pilomyxoid Astrocytoma of the HypothalamicChiasmatic Region
Authors: Mesrur Halefoglu Ahmet , Duran Ozel Betul
Published: April 2020

Pilomyxoid astrocytoma (PMA) is a recently described histological type of pilocytic astrocytoma (PA), but the tumors show histological differences. PMA has more aggressive malignant behavior than PA. Magnetic Resonance Imaging (MRI) may play a crucial role in the preoperative setting and also help to establish an appropriate therapeutic regimen. In this case report, we illustrated MRI findings of a hypothalamic-chiasmatic PMA in a 15-year-old female patient presenting with extensive leptomeningeal seeding. The patient was operated for total tumor resection, but could not survive the second post-operative day. We have comprehensively discussed the clinical, imaging, and histopathological features of these relatively rare tumors and also reviewed the recent literature.

Objective: The ankle-brachial index (ABI) as a simple test which can detect peripheral arterial disease (PAD). Therefore in this study we try to evaluate the diagnostic value of ABI for silent myocardial ischemia in diabetic patients and compare the results with myocardial perfusion imaging (MPI) results. Materials and Methods: All 149 diabetic patients in this study were categorized according to different parameters including sex, smoking, cholesterol, familial history, and high blood pressure, level of ischemia, myocardial infraction (MI), left ventricle (LV) volume, ejection fraction (EF), and wall motion. Then the relationship of ABI index and these parameters were investigated. Results: According to the calculated ABI the data was investigated based on ABI lower and higher than 0.9 .The frequency of ABI> 0.9 was 16 (11%) and< 0.9 was 133 (89%). There was no significant relationship between all the mentioned parameters and ABI index ( P -value: 0.05). Conclusion: This study suggests the ABI sensitivity and specificity for diagnose of silent ischemia in asymptomatic diabetic patients is very low and in this case ABI cannot replace MPI by any means.

Background: Acupuncture is an adjunct therapy to support infertile women received in vitro fertilization (IVF) treatment; however, the efficacy of this approach needs more evaluation.
Objective: This randomized clinical trial (RCT) study aimed to evaluate the influence of acupuncture on reproductive outcomes in women undergoing IVF treatment.
Materials and Methods: The study was carried out on 186 participants who had undergone IVF treatment in the Mother and Child Hospital between September 2015 and February 2016. Subjects were randomly divided into three groups: Acupuncture 25 min before embryo transfer (ET) (ACU1 group, n = 62), acupuncture 25 min before and after ET (ACU2 group, n = 62), and ET without acupuncture (control group, n = 62). Pregnancy rates (biochemical, clinical, and ongoing) were evaluated and compared between groups.
Results: There were significant differences between the ACU1 group and the control group regarding biochemical (p = 0.005), clinical (p = 0.006), and ongoing (p = 0.007) pregnancies. Also, our results showed that two-session acupuncture (ACU2) lead to a significant reduction in frequency of biochemical (p = 0.002), clinical (p = 0.003), and ongoing (p = 0.01) pregnancy rates when compared to the one-session acupuncture (ACU1). No significant difference was found between the ACU2 and control groups regarding the aforementioned terms (p = 0.50).
Conclusion: Acupuncture 25 min before ET significantly increased the IVF outcomes in women undergoing IVF compared with no acupuncture. Repeating acupuncture 25 min after ET did not improve the IVF outcome.
Key words: Acupuncture, Embryo transfer, In vitro fertilization, Pregnancy rate.

Introduction: Carpet industry is one of the most important, dangerous and traditional industries in Iran. Non-Ergonomic factors such as non-standard work tools, inappropriate physical postures, long hours of work and insufficient rest of carpet weavers can lead to musculoskeletal disorders. The purpose of this study was to determine the prevalence of musculoskeletal discomfort and its relationship with posture in rural carpet weavers in Boshruyeh city.
  Methods: This study is descriptive, analytical and cross-sectional. The sampling method was census-based and included all rural carpet weavers in Boshruyeh city who were active at least 6 months prior to the beginning of the study and were willing to cooperate (62 people). In order to investigate musculoskeletal discomforts, used from Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) and for posture assessment, The Occupational Repetitive Action Index (OCRA) method was used. The collected data by using SPSS software IBM 24 (Pearson correlation test) was analyzed.
  Results: The results showed that 98.39% of the workers felt discomfort at least in one of the 20 assessed regions. The most common discomfort of carpet weavers was 72.88% in the lower back region and the lowest incidence of discomfort was 9.68% in the hip/buttocks. There was a significant statistical relationship between scores of musculoskeletal discomforts in 11of 20 assessed regions with OCRA score (p <0.05), There was also a significant statistical relationship between age, work hours and work experience with CMDQ score (p <0.05).
  Conclusions: It seems Insufficient rest, Repetitive work, and incorrect posture are of factors affecting the musculoskeletal discomfort.observe the principles of ergonomics, especially having proper postures and regular rest along with stretching can be helpful in reducing the incidence of discomfort and musculoskeletal disorders.
Programa Future-se: impactos sobre a autonomia das Instituições Federais de Ensino e sobre o direito à educação

Published: April 2020

Este artigo possui como propósito refletir as implicações do Programa Future-se sobre a autonomia das Instituições Federais de Ensino e o direito à educação, neste caso, à educação superior. Para tanto, serão apresentados aspectos do cenário político de ataques aos direitos sociais dos brasileiros, a fim de analisar possíveis desdobramentos, tais como: o uso do Projeto de Lei como instrumento do atual governo para estreitar ainda mais as relações com o setor produtivo e empresarial, restrição da autonomia universitária e alteração das características precípuas e finalidades das universidades e institutos federais. A técnica de pesquisa utilizada foi a análise documental e bibliográfica, de abordagem qualitativa, e parte da compreensão de que as relações sociais são determinadas, historicamente, pelo modo de produção, obstinando a destruição da pseudoconcreticidade (KOSIK, 1976). A análise realizada nos permite afirmar que o Future-se não possui relação com a melhoria da qualidade da educação brasileira, mas vem à reboque das necessidades do capital a fim de obedecer demandas privadas que, em curto prazo, pretendem tornar as Instituições Federais de Ensino lócus de desenvolvimento de pesquisas e produção de conhecimentos comprometidos com a lógica da mercadorização da educação, e, portanto, alheia ao desenvolvimento integral dos estudantes e ao pleno gozo do direito à educação.

In order to find a connection between the alteration of oral tissues and genetic predisposition to inflammatory and destructive processes in oral media, the cytokine profile of the oral fluid of clinically healthy individuals was determined for various blood group affiliations according to the AB0 system. The group-specific features of individuals with B(III) blood group were revealed: an increase of 32,5% in the content of interleukin-6 and 63,1% in the content of interleukin-8 compared with similar data for people with 0(I), A(II), AB(IV) blood groups, which can predispose to the greatest activity of the inflammatory process in the oral cavity in individuals with antigen B. Confirmation of this fact is an increase of IgA antibodies to gliadin in the blood among patients with chronic generalized periodontitis with B(III) blood group, up to 5,00 U/ml (p<0,01), which indicates the processes of acute inflammation, and along with an increase in blood IgG antibodies to transglutaminase in comparison with a group of clinically healthy individuals, it serves as an indicator of damage to the body’s connective tissue at the molecular level. When examining the dental status, pronounced clinical manifestations of chronic generalized periodontitis were found in patients with A(II) blood group, the molecular foundation of which is the highest content of IgA and IgG antibodies to transglutaminase in the oral fluid (0,35 U/ml and 0,45 U/ml), which contributes to the activation of periodontal-destroying inflammatory and inflammatory processes, obviously, with a tendency to the chronic course of the disease. The studies performed allowed us to analyze in clinically healthy individuals a predisposition to alternative processes in oral environments, using gradation by group blood affiliation.
