AbstractThis paper represent a report of a case with ulnar nerve schwannoma (neurilemmoma), benign neurogenic slow-growing, tumors originating from Schwann cells along the course of a nerve (1) (2) (3). Schwannomas are the most common tumors of the peripheral nerves which occur in the adults (0.8–2%) (5). Usually they progress slowly and so they can remain painless swellings for a few years before other symptoms appear. Most of these lesions could be diagnosed clinically, are mobile in the longitudinal plane along the course of the involved nerve but not in the transverse plane (7). EMG, MRI, and ultrasonography are useful tools in the diagnosis. The definitive treatment of benign peripheral nerve schwannomatosis is complete enucleation of the tumor mass without damaging the intact nerve fascicles followed by confirmatory hystopathological examination (12). We present the case of a 62 years old right hand-dominant female who notice a slow increasing bulge over the inner aspect of her distal volar left forearm superior to the wrist, for a longer period of time not exactly specified; this was tracked and associated by pain, tingling and numbness over inner one and half fingers of her left hand in progress until the presentations. A diagnosis of soft-tissue tumor was presumed clinically. The other investigations were ultrasonography (US), nerve conduction studies (NCSs) such as sensory nerve action potential (SNAP) and compound muscle action potential (CMAP). In this case IRM was suggestive of a benign growth in her left ulnar nerve in the forearm region. Microsurgical techniques were used for ample enucleation of the tumor the distal volar left forearm. Subsequent histopathological examination confirmed the presumed diagnosis of a benign cellular schwannoma. At her last follow-up one month after surgery, the patient was neurological gradually improving sensory and motor function and she is highly satisfied with the results of surgery.

AbstractObjective: Spina bifida is one of the most severe birth defects and can happen as a result of disrupted primary neurulation. Congenital vertebra and costa anomalies are more frequently seen with spina bifida, and associated anomalies significantly affect the prognosis of affected children. In this study, we aimed to determine the incidence of scoliosis, costal anomalies, and vertebral deformations seen at the time of diagnosis and to statistically evaluate their concomitancies.Methods: Gender and mean ages of the patients were determined. The spina bifida patients were examined for deformation anomalies, butterfly vertebra, hemivertebra, wedge vertebra, costal anomalies and scoliosis. The relationships between these anomalies were evaluated.Results: 94 patients with a mean age of 11,5 months examined. The incidence of scoliosis was 21.8% among female infants and 17.9% among males. Rates of scoliosis with vertebra anomalies (hemivertebra, wedge vertebra) and costal anomalies did not differ significantly (P > 0.05). Wedge vertebra were the most frequent vertebra anomaly type with 38.2% ratio. Costal anomalies were detected in 25.5% of females and 20.5% of male infants. Hemivertebra and wedge vertebra were seen significantly more frequently in this group. Gender distribution did not differ between with and without any vertebra types.Conclusion: Congenital vertebra and costa anomalies are more frequently seen with spina bifida. We believe that these anomalies and relationship with spina bifida may demonstrate differences among different ethnic groups or locations. More detailed multi-centered studies performed on this issue will aid in the determination of etiologies, genetics, and treatment principles of these congenital anomalies.

Published: June 2016

Abstract
Subarachnoid pleural fistulas are rare. They have been described as complications of thoracic surgery, penetrating injuries and spinal surgery, among others. We present the case of a 3-year-old female child, who suffer spinal cord trauma secondary to a car accident, developing a posterior subarachnoid pleural fistula. To our knowledge this is the first reported case of a pediatric patient with subarachnoid pleural fistula resulting from closed trauma, requiring intensive multimodal management. We also present a management algorithm and a proposed classification. The diagnosis of this pathology is difficult when not associated with neurological deficit. A high degree of suspicion, multidisciplinary management and timely surgical intervention allow optimal management.

The patient presented with swelling in zygomatic fossa and imaging studies showed a mass originating in the right temporal bone. Gross total resection of the tumor was done and sent for histopathological study. The case was referred for radio-chemotherapy and had no recurrence up to eight months of follow up.
Influence of Sociocultural Context on Language Learning in Foreign Countries
Authors: Pazyura Natalia 
Published: June 2016

Abstract Professional foreign language training is offered to cultivate the ability to master cross-cultural communication in the sphere of future professional activity. By means of intercultural competence of foreign language we are raising professional competence, too. In countries where English is the native language, it is taught to speakers of other languages as an additional language to enable them to participate in all spheres of life of that country. In many countries where it is an official language and language of instruction, as most communication outside school is in the local languages it is taught as language to learn other disciplines. These are two contrasting contexts for enhancing the English language skills. In both settings there are concerns about students’ difficulties in developing adequate English proficiency to successfully learn content through that language. This paper analyzes the influence of sociocultural factors on the students’ motivation to learn English in different countries, reveals main problems and difficulties in oral English teaching practice, illustrates the relationship between oral English teaching and cross-cultural communication competence. On the one hand, cross-cultural communication plays an essential role in oral English teaching; besides, oral English teaching promotes cross-cultural communication competence. On the other hand, in some countries English is not the prerequisite of future successful career. But anyway the author insists on consistency of English teaching concept with that of the world. Improving the students’ cross-cultural oral communication ability is impossible without laying equal stress on cross-cultural communication competence and oral English teaching.

Abstract Out of the four fundamental interactions in nature, electromagnetics is one of them along with gravitation, strong interaction and weak interaction. The field of electromagnetics has made much of the modern age possible. Electromagnets are common in day-to-day appliances and are becoming more conventional as the need for technology increases. Electromagnetism has played a vital role in the progress of human kind ever since it has been understood. Electromagnets are found everywhere. One can find them in speakers, doorbells, home security systems, anti-shoplifting systems, hard drives, mobiles, microphones, Maglev trains, motors and many other everyday appliances and products. Before diving into the education system, it is necessary to reiterate its importance in various technologies that have evolved over time. Almost every domain of social life has electromagnetic playing its role. Be it the mobile vibrators you depend upon, a water pump, windshield wipers during rain and the power windows of your car or even the RFID tags that may ease your job during shopping. A flavor of electromagnetics is essential during primary level of schooling for the student to understand its future prospects and open his/her mind to a broad ocean of ideas. Due to such advancements this field can offer, study on such a field is highly beneficial for a developing country like India. The paper presents the scenario of electromagnetic education in India, its importance and numerous schemes taken by the government of India to uplift and acquaint the people about the importance of EM and its applications.
Mentoring as the Core Element of New Teacher Induction in the USA: Policies and Practices
Authors: Zembytska Maryna 
Published: June 2016

Abstract
The paper focuses on mentoring as the key strategy of novice teacher induction in the USA. The study reviews current mentoring/induction policies and trends in the U.S. system of in-service teacher training and support. The findings suggest that the conceptual framework, standards and practices of new teacher mentoring in the United States conform to the dynamic trends in education and organizational management. The conceptual modification of teacher mentoring manifests itself in the development of comprehensive and sustained formal induction programs based on the theories of educational leadership, adult learning, social interaction and collaborative learning. Quality induction programs are context-based and involve multiple stakeholders (schools, school districts, local educational organizations and agencies, partner universities, state departments of education etc). Diverse forms of mentoring (one-to-one, peer, group, reciprocal, online and needs-driven mentoring, etc.) are extensively combined with other induction components offered to beginning teachers and mentors during the whole induction period. The induction components include: summer courses, orientation sessions, workshops, seminars, webinars, conferences, interviews, informal meetings and celebrations, district-based mentor training programs etc. The quantitative data obtained through the analysis of the U.S. national surveys and research reports provides ground for highlighting those mentoring and induction programs which have significantly decreased turnover rates among new teachers, contributed to their professional development and improved academic achievement in public schools by providing students with quality instruction.

Authors: Aliyev Oktay 
Published: June 2016

Abstract The article consolidates information sources on the issues of future economists’ self-study organization at foreign universities. There has been carried out the study of approaches to the interpretation of the term “self-study process” in the contemporary scientific thought abroad. There have been specified the productive ideas of foreign experience which are to be understood and implemented into practice of domestic higher education institutions in terms of professional training of future specialists in the field of social and behavioural sciences majoring in Economics, including the following: 1) student self-study is supposed to be a mandatory part of the educational process, with the amount of time dedicated to being less than 65 percent. At the same time a student-personalized approach to each student should be implemented and the course of study, specifics of the subject being learnt should be taken into account; the teachers are expected to offer verbal consulting and ICT support (including university web resources) of student self-study; 2) while organizing the educational process (syllabi, curricula for students of different educational levels) it should be taken into account that there is a link between self-education of future economists with his/her practical activities along with development prospects of the sector; 3) organization of future economists’ self-study should be based on the student’s conscious attitude to learning, recognition of its role in meeting the challenges and solving the urgent problems of economic education (motivational component); on knowledge forming the basis for the individual’s self-study and determining his/her readiness for self-education in their future careers (cognitive component); on combination of skills and abilities of the individual, determining his/her functional readiness for professional self-education on challenging issues of economic sphere (operational and pragmatist component).

Published: June 2016

Abstract
Endothelial progenitor cells (EPCs) have prominent roles in vessel and tissue repair; however, their regenerative efficacy is diminished due to the poor survival in the hostile microenvironment of the injured organs. Recent data suggest a promising potential of volatile anesthetics for improving stem cell biology. Thus, we hypothesized that exposure to sevoflurane could stimulate growth and viability of cultured EPCs.
Total mononuclear cells were isolated from human umbilical cord blood by gradient centrifugation. After five days in culture, the cells were exposed for one or two hours to sevoflurane 2% or 4% in air/5% CO2, or only to air/5% CO2 (sham control) in a sealed modular chamber. 24 or 48 hours post-exposure, viability, proliferation and apoptosis were assessed using lactate dehydrogenase (LDH) leakage assay, a methyl tetrazolium salt (MTS) assay and FITC-annexin V/ propidium iodide (PI) staining, respectively.
LDH leakage was discretely lowered, whereas the levels of formazan were significantly increased (p < 0.05 for 1 h incubation with 4% sevoflurane at 24 hrs post-exposure, and with 2% sevoflurane at 48 h post-exposure) in the preconditioned cultures, proving no cytotoxic effects and increased proliferation in treated cells versus control samples. Early (p < 0.05) and late apoptosis (p < 0.05 only for 2% sevoflurane) were diminished following the procedure.
Thus, the commonly used sevoflurane anesthetic has protective effects on viability and proliferation of human early endothelial progenitor cells in vitro, suggesting a promising potential of anesthetic preconditioning for improving the regeneration of ischemic tissues.

Abstract
Background. The study aimed to evaluate the correlations of cognitive function with metabolic, nutritional, hormonal and immunologic parameters in patients with type 2 diabetes (T2D), in order to identify markers of cognitive impairment.
Material and methods. This cross-sectional study included 216 T2D patients and 23 healthy individuals (HC). The cognitive status was evaluated by the MoCA test. From HC and 145 T2D patients several parameters were also determined: C-peptide, vitamin B12, high-sensitivity CRP (by chemiluminescent immunometric assay), HbA1c, lipids, cortisol, TSH, Mg (by a Cobas 6000 analyzer), glucose (by glucose-oxidase method) and leptin and adiponectin (by ELISA method). Statistical significance was set at p < 0.05.
Results. There was a significant difference in the MoCA scores between HC and T2D groups (26.0(17.0-29.0) vs. 23.0(13.0- 31.0) points; p: 0.004). T2D patients with cognitive dysfunction were significantly older and less formally educated (p < 0.0001). Age negatively correlated with MoCA scores (-0.31; 95%CI:-0.42,-0.18; p < 0.0001). T2D patients had significantly lower visuospatial/executive (4.0(0.0-5.0) vs. 5.0(2.0-5.0) points; p: 0.04) and delayed recall scores (2.0(0.0- 5.0) vs. 3.0(1.0-5.0) points; p: 0.03) and lower serum Mg concentrations (0.81(0.12-0.99) vs. 0.92(0.41-1.35) mmol/l, p < 0.0001). Serum Mg levels positively correlated with MoCA scores (0.24, 95%CI: 0.07, 0.39; p: 0.003) and with visuospatial/ executive (0.30; 95%CI: 0.14, 0.45; p: 0.0002) and naming functions (0.18; 95%CI: 0.01, 0.34; p: 0.02).
Conclusions. Patients with T2D had significant cognitive impairment, with decrements in the visuospatial/executive and delayed recall domains. Younger age and higher education correlated with better cognitive function. Serum Mg levels correlated positively with overall cognitive function and with visuospatial/executive and naming domains.
