This article explains the need for the research in the field of engineering terminology, the process of teaching it in foreign languages, the comparative application of engineering terms in different languages and studying the development trends. Objective of the article is to describe the methodology of teaching mechanical engineering terminology on the basis of study research in the field of mechanical engineering as a complex of heavy equipment in industry that produces household appliances, as well as consumer electronics and products of defense importance. Methods of the investigation that enabled to: study and analyze mechanical engineering terms; develop methodology of teaching mechanical engineering terms; analyze selection and assessment criteria of case studies; analyze selection and assessment criteria of project-based teaching; organize pedagogical experiments and analyze their results. It is an integral part to investigate the sphere of machine-building and metalworking industries, the production of metal products, metal structures and the repair of machinery and equipment. Furthermore, the issues of teaching engineering terminology in order to form professional foreign language competence in technical students by means of using new pedagogical technologies are of high significance. Such as, typology of terms in the field of mechanical engineering, teaching terminology whereby case studies and projects, examples of case studies and study projects are given. It is also important to pay attention to the etymology and the sources of the formation of terms, their peculiarities and definitions in special contexts as a complex human speech and language activity. Results and discussion. The article discloses the processes of activating terminology for obtaining information, through cognitive activity. Research works in the field of mechanical engineering, the practical basis of teaching terms and its effectiveness are also analyzed. The terms, vocabulary related to the field of mechanical engineering, case studies and analysis of independent work assignments are taken into account in the organization and conducting the trainings defined in the pedagogical experiment. As a result of experimental research, it was proved by mathematical statistical methods that the efficiency was achieved by 15% in case studies and 17% in educational projects. It was found that the mean value of the scores in the experimental group was 17% higher than in the control group. Hence, the research conducted has proven to be effective. Conclusions. The difficulties that arise in the process of comparing terminological activities show not only the specificity of individual languages, but also the specific role of terms in the national language system. Comparing the terminology of the English and Uzbek languages in the field of mechanical engineering not only allows to determine the general and specific features of the terms of mechanical engineering in the two languages, but also provides an in-depth study of both terminological systems.

Background: With an increase in the aged population, there is a growing concern regarding the care of the elderly. This study aims to identify effects of cognicise-neurofeedback on health locus of control, depression, and quantitative electroencephalography (QEEG) alpha asymmetry in elderly women. Methods: A quasi-experimental control group pre-test–post-test design was used. Korean women aged 65 years or over at a senior welfare center were randomly allocated to the control (n = 12) or experimental (n = 19) groups from July to October 2019. The intervention consisted of cognicise (exercise with intensified cognitive activity) and neurofeedback twice a week for 10 weeks. The locus of control and depression were measured via self-reported questionnaires. QEEG alpha asymmetry was measured using BrainMaster. Results: Depression significantly decreased in the experimental group (t = 4.113, p = 0.001), while internality in the locus of control significantly decreased in the control group (t = 3.023, p = 0.012). On the other hand, QEEG alpha asymmetry index differences in F3-F4 between the pre-test and post-test were not significant in the experimental group (t = 0.491, p = 0.629) or control group (t = 0.413, p = 0.678). Conclusions: Due to the coronavirus disease (COVID-19) pandemic, contact between the elderly and healthcare workers in the clinical practice field has become more restricted. These findings can help decrease negative emotions among elderly women in the community based on an integrated neuroscientific approach.

The aim of this study was to evaluate the effect of implant surface treatment with carboxyethylphosphonic acid and fibroblast growth factor 2 on the bone–implant interface during the osseointegration period in vivo using an animal model. The present research was carried out in six minipigs, in whose left tibia implants were inserted as follows: eight implants with a standard surface treatment, for the control group, and eight implants with a surface treatment of carboxyethylphosphonic acid and immobilization of FGF-2, for the test group. At 4 weeks after the insertion of the implants, the animals were sacrificed for the histomorphometric analysis of the samples. The means of the results for the implant–bone contact variable (BIC) were 46.39 ± 17.49% for the test group and 34.00 ± 9.92% for the control group; the difference was not statistically significant. For the corrected implant–bone contact variable (BICc), the mean value of the test group was 60.48 ± 18.11%, and that for the control group, 43.08 ± 10.77%; the difference was statistically significant (p-value = 0.035). The new bone formation (BV/TV) showed average results of 27.28 ± 3.88% for the test group and 26.63 ± 7.90% for the control group, meaning that the differences were not statistically significant (p-value = 0.839). Regarding the bone density at the interthread level (BAI/TA), the mean value of the test group was 32.27 ± 6.70%, and that of the control group was 32.91 ± 7.76%, with a p-value of 0.863, while for the peri-implant density (BAP/TA), the mean value of the test group was 44.96 ± 7.55%, and that for the control group was 44.80 ± 8.68%, without a significant difference between the groups. The current research only found a significant difference for the bone–implant contact at the cortical level; therefore, it could be considered that FGF-2 acts on the mineralization of bone tissue. The application of carboxyethylphosphonic acid on the surface of implants can be considered a promising alternative as a biomimetic coating for the immobilization of FGF-2. Despite no differences in the new bone formation around the implants or in the interthread or peri-implant bone density being detected, the biofunctionalization of the implant surface with FGF-2 accelerates the mineralization of the bone–implant interface at the cortical level, thereby reducing the osseointegration period.

AbstractSerum immunoglobulin (IgG, IgA and IgM) levels were determined in patients with chronic tonsillitis before and one month after tonsillectomy. The preoperative levels of serum IgG, IgA and IgM were significantly higher when compared with the controls. The increase may be due to repeated antigenic stimulation. The post-operative levels for the three immunoglobulins were decreased; however, a significant reduction was observed for IgG only where the mean value was comparable with the control group. The data confirm that tonsillectomy does not disturb the humoral immune system of the body.

Background: Diabetes mellitus is a metabolic disorder of multifactorial origin characterized by hyperglycemia and disturbances of glucose , fat and protein metabolism. Hypomagnesemia is been associated with chronic and uncontrolled diabetes mellitus. Magnesium deciency in diabetes is known to be associated with increased risk of microvascular and macrovascular complications. The aim of this study is to estimate fasting plasma glucose and serum magnesium levels and to assess the correlation of hypomagnesemia with abnormal fasting plasma glucose values. Material and Methods: The study was done at Government Medical College, Nizamabad. 80 subjects were recruited out of whom 40 apparently normal persons were taken as control group and the second group of 40 patients with known history of diabetes. The fasting plasma glucose(FPG) was estimated by GOD-POD method and serum Magnesium(Mg) levels were estimated using the Chemchek Mg kit which is based on Xylidyl Blue with ACTS method. Results :The mean values of fasting plasma glucose was 87.1 mg/dL in non diabetics when compared to 159.4 mg/dL in diabetics while Serum magnesium levels in control subjects had a mean value of 2.19mg/dLand 1.8mg/dLin diabetics. The data was analysed and found to be statistically signicant with a negative correlation between plasma magnesium and fasting blood glucose. Conclusion: There is signicant hypomagnesaemia which correlates increased fasting plasma glucose values in diabetics when compared to non diabetics and therefore assessing the serum magnesium levels may help in reducing risk of complications.

Introduction. At the present stage, the occupational pathology of the skin remains one of the significant medical and social problems. In this regard, special attention is paid to the early diagnosis of sensitization to industrial chemical allergens to target occupational allergic diseases. The aim of the study was to study the changes in clinical and laboratory parameters in the formation of allergic skin diseases in workers during nickel plating. Material and methods. Three hundred eighty-nine employees of the machine-building enterprise were examined. The leading group consisted of 214 people exposed to harmful chemical factors of production. Group of intact persons 175 people is represented by employees who do not come into contact with harmful factors of the production environment. The condition of the skin of workers was analyzed. Laboratory studies of oxidative metabolism and immune status were performed according to unified methods. The nickel content in the urine was determined by voltammetry. Results. At the studied enterprise, 38,3% of workers were diagnosed with occupational skin diseases (epidermosis, allergic dermatitis, eczema). In the formation of dermatological morbidity, an increase in the activity of alkaline (ALPn) and acid (ACPn) phosphatase of neutrophils by 1,7-2.2 times and inhibition of succinate dehydrogenase (SDH) and neutrophil myeloperoxidase (MPn) by 1.2-1.5 times relative to the control group was found. On the part of the immune system, there was an activation of the suppressor function of T-lymphocytes (CD8+); B-lymphocytes (CD20+), an increase in the content of immunoglobulins IgG, total IgE, circulating immune complexes by 1.5-2.0 times and a decrease in the levels of immunoglobulins IgA, IgM by 3.0-5.0 times compared to the control. The relationship between the nickel content in the urine of workers and changes in the indicators of ACPn (r = 0.76), MPn (r = -0.87), (CD4+) (r = -0.91), (CD8+) (r = 0,86), general IgE (r = 0.92), indicating the priority role of nickel compounds in the formation of allergodermatoses in workers. Conclusion. The proposed complex of biomarkers aims to detect early the initial forms of allergodermatosis and the formation of risk groups for the timely rehabilitation of electroplating workers.

Highly active antiretroviral therapy (HAART) is considered toxic and has other life-threatening side effects. Our aim was to evaluate the haematotoxic effects of lamivudine, zidovudine, and nevirapine fixed-dose combinations in Albino Wistar rats. Fifty (50) three (3) months old male Albino Wistar rats weighing between 200 and 250 g were randomly assigned to five (5) groups (A, B, C, D, and E). Group A served as control. Two (2 mLs) of venous blood was aseptically collected on Days 5, 10, 15, 20, and 25 of treatment. Red blood cell (RBC) mean value recorded statistically significant increase () in groups B and C when compared with the control group on Day 5. However, there was a statistically significant decrease () in RBC, haemoglobin concentration (Hb), packed cell volume (PCV), and some red cell indices on Day 10. In addition there was no statistically significant difference () in all the parameters evaluated when the test group was compared with the control on Day 25. Furthermore, there was a time-related statistically significant increase () in the two major blood cells—RBC and platelet counts. From the result of this present study, it can be concluded that HAART when administered in fixed-dose combinations have no subacute haematotoxic effects.
