Degenerative Cervical Myelopathy: Pathophysiology and Current Treatment Strategies
Authors: Choi Sung Hoon , Kang Chang-Nam
Published: October 2020

Chronic compression or ischemia of the spinal cord in the cervical spine causes a clinical syndrome known as cervical myelopathy. Recently, a new term “degenerative cervical myelopathy (DCM)” was introduced. DCM encompasses spondylosis, intervertebral disk herniation, facet arthrosis, ligamentous hypertrophy, calcification, and ossification. The pathophysiology of DCM includes structural and functional abnormalities of the spinal cord caused by static and dynamic factors. In nonoperative patients, cervical myelopathy has a poor prognosis. Surgical treatments, such as anterior or posterior decompression accompanying arthrodesis, arthroplasty, or laminoplasty, should be considered for patients with chronic progressive cervical myelopathy. Surgical decompression can prevent the progression of myelopathy and improve the neurologic status, functional outcomes, and quality of life, irrespective of differences in medical systems and sociocultural determinants of health. The anterior surgical approach to the cervical spine has the advantage of removing or floating the intervertebral disk, osteophytes, and ossification of the posterior longitudinal ligament that compress the spinal cord directly. The posterior surgical approach to the cervical spine is mainly used for multisegment spinal cord compression in patients with cervical lordosis. In this review article, we addressed the pathophysiology, clinical manifestations, differential diagnosis, and treatment options for DCM.
Historia de la caficultura en Chiapas (1880-2010). Apuntes de una evolución social y ambiental
Authors: Montoya David , Toledo Víctor Manuel
Published: October 2020

En el presente texto se analizan los factores que en poco más de un siglo propiciaron y condujeron la caficultura en Chiapas. Conforme las plantaciones de café se propagaron al interior del estado y, con base en los factores que hicieron esto posible, se presenta una periodización del desarrollo de la caficultura. Se muestra que la producción cafetalera es un proceso de evolución socioambiental, evidenciado por la transformación de las grandes fincas, de propietarios extranjeros y luego nacionales, a más de un centenar de empresas sociales o cooperativas, principalmente de propietarios indígenas que producen café en complejos sistemas agroforestales a escala familiar y que se articulan y organizan a distintos niveles. Esto demuestra un cambio en la manera de concebir la producción cafetalera. Si al principio ésta estaba dirigida hacia la rentabilidad económica promovida a través de la especialización, la dependencia tecnológica y la exportación del producto, dejando así una profunda huella en el paisaje, entrado el siglo XXI, la racionalidad productiva comenzó a tomar el rumbo hacia la sustentabilidad. Lo anterior se debe, en parte, a una combinación del mercado, la diversificación productiva, la no dependencia de insumos externos y la producción a pequeña escala. Se trata de un cambio afín con las sabidurías tradicionales y a contracorriente de la globalización dominante. Esto es, un fenómeno de evolución social y ambiental derivado de una histórica resistencia biocultural.
From Musicology to the Cultural Direction of Music Education Pedagogy: Research Introspection
Authors: Rapatskaya Lyudmila A.
Published: October 2020

The article describes the role of the scientific school by E. B. Abdullin in the formation and gradual development of the author’s research positions in the field of pedagogy of higher school music education. The first stage is characterized by considering problem of forming the artistic culture of future music teachers in a pedagogical University.The research embodied in his doctoral thesis, developed under the influence of the vectors of musicological and pedagogical thought. In includes analyses of the interaction of music with other art forms as manifestations of the General laws of artistic activity of man, revealed in the phenomenon of artistic culture. Pedagogical interpretation of artistic culture allowed us to consider this category: a) as an integral component of the content of music and pedagogical education; b) as a professionally significant quality of the music teacher’s personality. The concept changed the status of historical and theoretical training of future teachers-musicians, which received the working title “pedagogical musicology”. The content of pedagogical musicology was determined by a culturological approach to the learning process, designed to solve practical problems of mastering music in synchronic and diachronic interaction with other types of arts.The second stage is to expand the cultural component of professional training of music teacher, becoming a cultural orientation that integrates musicology, cultural studies and the pedagogy of music education on the basis of higher spiritual principles of music as an art form. The cultural direction allows developing new scientific approaches in the content of master’s educational programs in line with the methodological concept by E. B. Abdullin.

Published: October 2020

This article is an attempt to show the beginning of Eduard Borisovich Abdullin’s creative path in the pedagogy of music education, in particular, his experience in teaching as an artistic director and conductor of the choir studio “Melodia” of the Palace of Pioneers in the city of Podolsk, Moscow Region. As a graduate student of the Lenin Moscow State Pedagogical Institute, the young teacher achieved tremendous creative success: the choir studio under his direction performed in the Great Hall of the Moscow Conservatory, the Column Hall of the House of Unions, the P. I. Tchaikovsky Concert Hall, in the Kremlin Palace of Congresses; toured in the cities of the USSR and European countries. On the first television channel, two hour-long television programs were shown. The studio of the State House of Radio Broadcasting and Sound Recording has released educational records. For almost half a century, the “Melodiya” studio continued to meet with its leader, and all members of the choir strove to attend them in order to meet their Teacher again. Special attention is paid to the significance of the fundamental works by Eduard Borisovich Abdullin, which became the basis for the pedagogical interpretation by the author in his research activities of the conceptual provisions of the methodology of pedagogy of music education. The sequential expansion of the problem field of the conducted musical pedagogical research is described: from the theoretical substantiation of the model for the development of the Central Russian folk song tradition by children to the formation of a new direction of research searches associated with the use of various vocal techniques at the junction of different genres.

This article presents the results of the research methods of structures aligning during installation in the vertical plane. The analysis and research of existing methods of structures alignment in the vertical plane, used in the conditions of enterprises engaged in the installation of metal tanks. The results of the research showed that the applied alignment methods in the vertical plane have some drawbacks, in particular, after aligning, additional calculations are required. And also for alignment of sliding timbering, columns and wall panels use some theodolites, including vertical allotment. Laser devices and theodolites with visual system were also investigated. However, all the methods considered with the use of these devices are quite time-consuming and a significant number of tools and equipment are used. A device is proposed to control the shape and location of flat surfaces using the principle of similarity of triangles allowing obtaining a straight line of intersection of lasers in space parallel to the plumb line. Developed devices are cheap, easy to use and manufacture. With the use of the proposed technique, there is no need to use several working and expensive devices. The developed devices can significantly reduce the alignment time of building structures in the vertical and horizontal planes.

In this work, the temperature dependences of the electrophysical characteristics (electrical capacitance, electrical resistance, dielectric permittivity) were investigated in the range of 293-483 K for coal ash of the Maikuben basin (Kazakhstan) in its initial form, after electromagnetic (EM) and electrical discharge (ED) treatments. The temperature ranges in which the material exhibits both semiconductor properties and metallic conductivity are established. The band gap width (ΔE) was calculated for the studied samples. The measurement results showed that in comparison with the initial ash and ash after the EM treatment, the ash after the ED treatment has the highest values of electrical capacitance and dielectric permittivity and the lowest electrical resistance. Analysis of the research results showed that coal ash after ED treatment seems promising as a prepared raw material for its further thermochemical processing with the extraction of such valuable components as rare metals, silica, alumina, as well as a capacitive material (capacitor) and semiconductor.
Development of harmonized HPTLC methods for determination of polyphenolic compounds of tinctures
Authors: Хохлова К. О.
Published: October 2020

The tincture is a traditional liquid dosage form for the pharmaceutical market of Ukraine. Today, the range of the tinctures of Ukrainian manufacturers has 21 different items, while only six monographs on different tinctures are included in the State Pharmacopoeia of Ukraine. For standardization of tinctures, different combinations of specific and non-specific physical and chemical methods are used. The high-performance thin-layer chromatography (HPTLC) is a modern and specific chromatographic method, that can be used for the identification of polyphenolic substances responsible for a wide range of pharmacological activities of the tinctures.
The purpose of the study was to identify and compare chromatographic fingerprints (images of chromatograms and peak profiles from images) of flavonoids and phenylpropanoids of 10 tinctures of Ukrainian production in the harmonized mobile phases, to select for each tincture the specific marker zones, to determine the suitability of the specified chromatographic conditions for standardization of the tincture and the possibility to perform in these conditions the quality control for several different tinctures in-parallel.
The objects of the investigation were Hawthorn tincture, Peppermint tincture, Sage tincture, Motherwort tincture, Calendula tincture, Sophora tincture, Echinacea purpurea tincture, Valerian tincture, Peony tincture, Eucalyptus tincture. The research was carried out using the HPTLC method in the HPTLC automatic herbal system (CAMAG, Switzerland) on the base of two laboratories.
For each investigated tincture, the determination and comparison of HPTLC chromatographic fingerprints (images and peak profiles of images) of flavonoids and phenylpropanoids obtained in different harmonized mobile phases were performed.
In the harmonized chromatographic conditions the difference in separation of the bioactive substances was determined; the characteristic marker substances of the tinctures were identified; the suitability of the mobile phase for individual analysis of the tincture or in-parallel analysis of different tinctures on the same plate were determined; the possibility to replace one mobile phase by another, if needed, was determined.
Proposed HPTLC methods were developed using modern procedure and approach. These allow to reduce of the scope and time of analysis, optimize the economical and labor costs. The findings are of special importance for the pharmaceutical manufacturers and quality control laboratories that perform analysis on a large scale.

Porqué Colombia no exporta más
Authors: García-García Jorge , López-Valenzuela David C. , Montes-Uribe Enrique
Published: October 2020

Este trabajo explica cómo los costos de comerciar (protección y otros costos) desestimulan las exportaciones manufactureras y por qué Colombia exporta mayoritariamente productos primarios. Para esto, además de una revisión de literatura y una descripción del desempeño exportador colombiano, se presenta una metodología que mide la protección total causada por el arancel y las medidas no arancelarias (MNA) y que permite generar una serie de la protección verdadera para el período 1950-2019. Los resultados muestran que el país no ha explotado su potencial exportador de manufacturas porque los incentivos para hacerlo han sido magros, un resultado de la alta protección a la producción local, de una infraestructura escasa y de unos servicios logísticos costosos.

This article is devoted to a comparative analysis of the results of the ReMath project (Representing Mathematics with digital media), devoted to the study of digital representations of mathematical concepts. The theoretical provisions and conclusions of this project will be analyzed based on the theory of the information environment [1], developed with the participation of one of the authors of this article. The analysis performed in this work partially coincides with the conclusions of the ReMath project, but uses a different research basis, based mainly on the work of Russian scientists. It is of interest to analyze the work of the ReMath project from the conceptual positions set forth in this monograph and to establish links between concepts and differences in understanding the impact of computer tools (artifacts) on the process of teaching mathematics. At the same time, the authors dispute the interpretation of some issues in Vygotsky’s works by foreign researchers and give their views on the types and functions of digital artifacts in teaching mathematics.
The Relationship of Goal-Setting in the Teaching of Mathematics with its Technological Support
Authors:   Saint-Petersburg Electrotechnical University, 5, building 3, st. Professora Popova, 197376, Saint Petersburg, Russia, Pozdnyakov Sergey N.
Published: October 2020

Technological support of teaching mathematics depends on what methodological and pedagogical goals are put for learning. Achieving or failing to achieve these goals is connected with the used type of feedback or in other words, the method of assessing the educational activities of students. In this work, two types of assessment are contrasted: a test form of knowledge testing (implemented by a system of mid-term and final exams) and a formative assessment (determined by the teacher’s informal reaction to the student’s productive activities and the way these activities are organized). It is shown that the first type of assessment corresponds to the consideration of the curriculum as a learning goal, the second — as a learning tool. In the first case, the purpose of training is the acquisition of specific knowledge and skills, and in the second, the mastery of the general mechanisms of educational activity inherent in a given subject area (mathematics). For the first goal, it is effective to use template tasks including generated exercises and simulators, for the second — to use various tools that support constructive and research activities. The article shows how “non-invasive monitoring” is used to achieve the second goal, when the teacher and the student are not on opposite sides of the academic barrier (the student answers — the teacher sets a mark), but on the same side and jointly perform actions to create conditions for the most effective mastery of the course material by each student. The basis of non-invasive monitoring is modeling the presentation of the results of this activities to the scientific community, including all intermediate stages of such activities. Instead of testing knowledge and issuing formal marks, feedback is used, various approaches and ways to solve the problem are discussed together, and monitoring is limited to students’ self-esteem, which is not necessarily communicated to the teacher. At the same time, the discussion process itself is open, and the teacher can always evaluate the problems of students, without turning them into an instrument of formal pressure on the student by third parties.

Published: October 2020

The need to formulate qualifications and prepare students for the digital future is changing the teaching strategies and approaches to university education in the direction of digital design of the learning process. The expandable space of accessible data allows the use of new educational data mining (EDM) methods in order to explore unique data types, understand student actions activity, predict academic results, improve process performance, make management decisions and adapt the learning environment. The objective of this study is to create a personalized educational environment for individual accompaniment support of students on the basis of a model of cognitive potential. The task of supporting the learning process is to obtain information on the dynamics of cognitive growth (“growth” of the knowledge level) of each student based on the data obtained during the learning process. The task of differentiating students, predicting the success of training to improve the adaptation and customization of the learning process is considered. An approach to predicting the success of learning based on a cognitive model is important for understanding the productivity of learning materials by students in an informationrich environment. The task of differentiating students, predicting the success of learning to improve adaptation and tuning the learning process is considered. Organization of feedback in the structure of the learning process based on student differentiation allows you to manage and customize learning scenarios to improve the adaptation of the individual process. An integrated web environment combines traditional learning tools with innovative digital online tools.

Living Hadis Penutupan Lapak Jual Beli Ketika Waktu Shalat di Kampung Madinah Desa Temboro Karas Magetan Jawa Timur
Authors: Khamim  , Hadziq Hisbulloh
Published: October 2020

One of the interesting phenomena in the "Kampung Madinah" in Temboro Karas Magetan is the tradition of closing shop when the prayer time. The urgency in this research is to review these practices and explain their correlation with the hadith or sunnah of the Messenger of Allah. The research is field research that limits the problem to the application of the value of the sunnah to the tradition of closing shop in the kampung Madinah. The approach used is the sociology of knowledge which implies that reality is socially constructed. The result is that the tradition of closing shop when prayer time is the process of conveying the understanding conveyed by the followers of Jamaah Tabligh through the study of the book Fad}a>il al-A'ma>l which is recited at both bayan and ta'lim. Thus the closing shop when the prayer time is the actualization of the understanding of fiqh inspired by the hadith about the superiority of prayer in congregation.

Aim. In this paper we present anthropometric characteristics of young adults permanently living in three areas with different ecological risks in the Aral Sea region. The main hypothesis is that the exposure to organochlorine pesticides (OCPs) in early childhood combined with factor associated with Aral Sea disaster (ASD) may have consequences for body composition in adulthood. Methods. A cross-sectional study. Altogether, 33 anthropometric parameters including body mass, length, sizes of extremities, chest, pelvis, and skinfold thickness were measured in 320 volunteers (135 males, 175 females) born in 1990-1995 before implementation of measures for liquidation of the ASD consequences. The participants were divided into three groups by ecological characteristics of the place of residence: 1 - critical, 2 -relatively optimal and 3 - optimal. Numeric data were analyzed by Kruskal-Wallis tests with Mann-Whitney post-hoc tests with Bonferroni correction for multiple comparisons. Categorical data were compared using exact chi-squared tests for binomial distribution. Results. Young men living in critical area had significantly lower values for body mass, arm length, chest circumference, waist circumference, skinfold thickness compared to their counterparts in other groups. Women from the second group had significantly greater average values for all studied characteristics compared with the two other groups. Conclusions. Men from the most ecologically disadvantaged areas had signs of suboptimal bone development. The observed differences in arm length and the size of the major joints in men may by associated with the anti-androgenic effect of OCPs before and during puberty while the opposite pattern revealed in females may be partly explained by estrogenic effect of OCPs. Our findings are in line with the results from the literature on endocrine disruptor chemicals.

Published: October 2020

Excessive production of reactive oxygen species (ROS) are implicated in the pathogenesis of numerous disease states. However, direct measurement of in vivo ROS in humans has remained elusive due to limited access to appropriate tissue beds and the inherently short half-lives and high reactivity of ROS. Herein, we describe a novel technique by which to measure in vivo ROS in human skeletal muscle. Microdialysis probes were inserted into the vastus lateralis of eight healthy volunteers. Amplex Ultrared, a highly specific fluorogenic substrate for hydrogen peroxide (H2O2), and horseradish peroxidase (HRP), were perfused through microdialysis probes, and outflowing dialysate was collected and fluorescence was measured. Extracellular H2O2 that crossed the microdialysis membrane was measured via fluorescence of the dialysate. Superoxide dismutase (SOD) was then added to the inflowing perfusion media to convert any superoxide crossing the microdialysis membrane to H2O2 within the microdialysis probe. Fluorescence significantly increased (P=0.005) upon SOD addition. These data demonstrate the feasibility of measuring both in vivo H2O2 and superoxide in the extracellular environment of human skeletal muscle, providing a technique with a potential application to a wide range of circulatory and metabolic studies of oxidative stress.

The aim of our study was to investigate adrenocortical function in the context of disease activity and inflammatory status in premenopausal RA females. Adrenal glucocorticoid and androgen responses to the 1 µg ACTH 1-24 test were investigated in 23 premenopausal RA and in 15 age- and BMI-matched healthy females. Twelve RA patients were on low-dose prednisone (<8.5 mg/day). Patients with DAS28>3.2 had lower (p<0.05) total plasma cortisol, 17-hydroxyprogesterone, dehydroepi-androsterone and androstenedione responses in the ACTH test compared to healthy controls. Patients with DAS28>3.2 had lower (p<0.05) dehydroepiandrosterone response in the ACTH test compared to patients with DAS28≤3.2. C-reactive protein (CRP), DAS28, and interleukin (IL)-6 negatively correlated with androstenedione response to ACTH 1-24. Responses of all measured adrenal steroids were lower (p<0.05) in patients on low-dose glucocorticoids compared to healthy controls. RA patients not treated with glucocorticoids had lower total cortisol response (p=0.038) but did not differ in free plasma cortisol in the ACTH test. The results indicate an association of increased disease activity with a decrease in adrenal androgen production in RA and normal cortisol bioavailability in patients not treated with glucocorticoids.

Cholestasis is characterized by the elevation of serum total bile acids (TBA), which leads to the production of both free radicals and oxidative stress. Although they do not share the same mechanisms, membrane glycosphingolipids (GSL) and the antioxidant enzyme heme oxygenase-1 (HMOX1) both act against the pro-oxidative effect of TBA. The aim of the study was to assess the role of HMOX on GSL redistribution and composition within hepatocytes in the rat model of estrogen-induced cholestasis. Compared to the controls, an increase of total gangliosides in the liver homogenates of the cholestatic group (P=0.001) was detected; further, it paralleled along with the activation of their biosynthetic b-branch pathway (P<0.01). These effects were partially prevented by HMOX activation. Cholestasis was accompanied by a redistribution of GM1 ganglioside from the cytoplasm to the sinusoids; while HMOX activation led to the retention of GM1 in the cytoplasm (P=0.014). Our study shows that estrogen-induced cholestasis is followed by changes in the synthesis and/or distribution of GSL. These changes are not only triggered by the detergent power of accumulated TBA, but also by their pro-oxidant action. Increases in the antioxidant defenses might represent an important supportive therapeutic measure for patients with cholestatic liver disease.

Published: October 2020

The soft actuator possesses the characteristics of flexibility, environmental adaptability, and human–machine interaction. Firstly, aiming to resolve the limitation of variable stiffness performance of a traditional pneumatic artificial muscle (PAM) actuator, based on the antagonistic mechanism of extensor and contractor muscles, a novel pneumatic soft actuator coupled of extensor and contractor muscles is proposed in this paper. The actuator can perform the compound action of elongation/contraction, and the stiffness of it can be controlled by adjusting the elongation and contraction forces. Secondly, based on the deformation principle of woven and elastic fabric layers, the mechanical characteristics model of the actuator is established and simulated. The mechanical properties of the actuator are tested under different pressures and deformation displacement and the variable stiffness characteristics of the actuator are verified. Finally, actuators are utilized to manufacture a soft mechanical manipulator, which can achieve variable stiffness in a fixed bending attitude.

The ability of tall fescue (Festuca arundinacea L.) and orchardgrass (Dactylis glomerata L.), to remediate leachates polluted with S-metolachlor (SMR) has been assessed in static hydroponic cultures. Different SMR concentrations (0.25, 1.00, and 2.00 mg L−1) were applied in the growth media to test the capacity of the two grasses to tolerate and uptake this herbicide, and to regrowth after mowing. S-metolachlor did not severely affect the dry weight aerial biomass of D. glomerata and F. arundinacea, which were reduced by 5% and 10%, respectively, when compared to the untreated control, regardless of the SMR concentrations in the leachate. The regrowth ability of aerial biomass after mowing was reduced at the different SMR concentrations, according to a dose–response model. The SMR concentrations, which reduced the regrowth ability of F. arundinacea and D. glomerata of 10% and 30%, were found to be EC10 (Effective Concentration) of 0.21 and 0.38 mg L−1 and EC30 of 0.45 and 0.74 mg L−1, respectively. These values could be assumed as the SMR concentrations that were well tolerated by both the species, without compromising their aerial biomass regrowth. Finally, tall fescue was found to be more effective and faster than orchardgrass in decreasing the SMR in the leachate and, therefore, this species should be preferred to be used in the vegetative buffer strips (VBS).

Potato tuber yields depend on nitrogen (N) supply, which affects source–sink relations. Transcriptome sequencing of the foliar source using a single field trial identified gene expression responsive to 180 kg N ha−1. The expression of N-responsive genes was further analyzed in the next stage using a NanoString nCounter over an expanded number of foliar samples from seven field trials with varying N rates, sites, and cultivars. Least absolute shrinkage and selection operator (LASSO) regression models of gene expression predictive of yield, total plant N uptake, and tuber-specific gravity (proxy for dry matter) were built. Genes in the LASSO model for yield were associated with source–sink partitioning. A key gene regulating tuberization and senescence, StSP6A Flowering locus T, was found in the LASSO model predicting tuber yield, but not the other models. An aminotransferase involved in photorespiratory N assimilation and amino acid biosynthesis was found in all LASSO models. Other genes functioning in amino acid biosynthesis and integration of sulfur (S) and N metabolism were also found in the yield prediction model. The study provides insights on N responses in foliage of potato plants that affect source–sink partitioning. Additionally, N-responsive genes predictive of yield are candidate indicators of N status.
