Authors: Akard Terrah , Gilmer Mary Jo , Hendricks-Ferguson Verna
Published: April 2020

UNSTRUCTURED

As a result of COVID-19 restrictions, researchers are dealing with many studies being suspended, resulting in significant and unprecedented negative consequences. An alternative response to COVID-19 is for scientists to consider modifying in-person research strategies to remotely delivered and conducted research studies. Our objective here is to provide guidance and examples from our work in palliative care to other researchers who need to consider remotely delivered research technologies in response to COVID-19 to continue their ongoing or future research. Case examples from our research are presented, including (a) remote participant recruitment via Facebook advertising and (b) a remotely delivered web-based legacy intervention in a pediatric oncology randomized clinical trial. Challenges to modifying in-person approaches to remote technologies are also discussed, with examples of advantages and disadvantages presented from a study testing a human-animal interaction intervention for children with cancer. Scientists can consider remotely delivered methodologies to continue their research in many situations, but remotely delivered strategies are not appropriate or feasible for every study.

Published: April 2020

UNSTRUCTURED

COVID-19 pandemic has become a major threat to the country. To date, well-tested medication or antidote is not available to cure this disease. According to WHO reports, COVID-19 is a severe acute respiratory syndrome which is transmitted through respiratory droplets and contact routes. Analysis of this disease requires major attention by the Government to take necessary steps in reducing the effect of this global pandemic. In this study, outbreak of this disease has been analysed for India till 30th March 2020 and predictions have been made for the number of cases for the next 2 weeks. SEIR model and Regression model have been used for predictions based on the data collected from John Hopkins University repository in the time period of 30th January 2020 to 30th March 2020. The performance of the models was evaluated using RMSLE and achieved 1.52 for the SEIR model and 1.75 for the regression model. The RMSLE error rate between the SEIR model and a Regression model was found to be 2.01. Also, the value of R0 which is the spread of the disease was calculated to be 2.02. Expected cases may rise between 5000-6000 in the next two weeks of time. This study will help the Government and doctors in preparing their plans for the next two weeks. Based on the predictions for short-term intervals, these models can be tuned for forecasting in long-term intervals.
New Trends in Translation and Interpretation Teaching/Training
Authors: Akpaca Dr Servais Martial
Published: April 2020

The aim of this paper is to discuss four aspects of translation and interpreting teaching, namely the pedagogical approach (i.e., objectivism vs. constructivism), translation ability and interpreter performance as well as translation and interpreting theory and practical classroom activities. The methodology is mostly descriptive and constructive in the sense that the paper “constructs” translation ability and interpreter performance and describes relevant teaching approaches to be adopted. One of the findings of the paper is that translation and interpreting teaching should either validate or change traditional pedagogical methods by new and more effective ones. Another finding of the paper is that translation and interpreting teaching should indicate clear-cut learning objectives, design adequate curricular materials and shed light on professional ethics and policies.
Occupational Participation of Persons with Schizophrenia: Exploring Issues of Job-Termination in Supported-Employment
Authors: Niap Cindy , Bakar Abdul Kadir Abu , Loh Siew Yim,
Published: April 2020

Occupational participation in a supported-employment is a rehabilitation strategy to improve both vocational and non-vocational domains of people with psychiatric disabilities, enabling them to access and/or re-enter employment. This study aims to identify the factors associated with unsatisfactory job-termination among the participants of supported-employment to inform future intervention. A cross-sectional survey was conducted on a group (with a diagnosis of schizophrenia) who participated in a supported-employment program in a large psychiatry institution in Malaysia. Within the first week of job termination, interviews were conducted with three subgroups independently - the participants, the employers and the hospital employment specialists, using the Job-Termination Interview. Factors linked to job-termination and job-accommodation were analysed using univariate and multivariate logistic regression.Key reasons for job termination were- poor job performance (n = 32; 47.1%), interpersonal issue (n = 31; 45.6%), medical illnesses (n = 30, 44.1%), incompatibilities between work-schedule and environment (n = 30; 44.1%), and job-dissatisfaction (n = 29, 42.6%). Key factor for sustaining job/ job-accommodation was “higher pay” (n = 4; 33.3%). Overall, an unsatisfactory trend of job terminations was observed where many (n = 53; 77.9%) quit their job without a ready job at hand. Unsatisfactory job-terminations were associated with three factors -(i). Enrolment in the Individual Placement-Support (IPS) (Adj. OR = 10.70, 95% CI 1.32-86.98, p = 0.012), (ii). Unstable medical issues (Adj. OR = 22.51, 95% CI 1.74-291.08, p = 0.003), (iii). Interpersonal issues (OR = 18.26, 95% CI: 2.24-149.15, p < 0.001).Most participants terminated their jobs in an unsatisfactory manner (77.9%). A high 63.2 percent quit their job without another ready-job at hand, while 14.7 percent were fired. Unsatisfactory job-endings were correlated to, poor job-performance, interpersonal problems and medical illnesses. Occupational re-entry intervention program must be tailored to the individual levels and needs, and be fully integrated within the clinical system to ensure job-person-environment fit, in order to improve job-experience and to lower unfavourable job terminations.

In the context of the current migration crisis, in the public discourse and media reporting, different terms are used interchangeably to denote persons who are coming to Serbia from the states and the regions which "produce refugees": irregular migrants, immigrants, migrants, refugees, asylum seekers. The paper aims at providing distinctions between core terms: migrant, refugee and asylum seeker and to point out that, although it is not easy to draw demarcation line between these terms, they do not have the same meaning. These terms define essentially different (legal) status, which determines the treatment of these categories of people, the corpus of rights they are entitled to according to the regulations of the international law and national legislations, as well as the responsibilities and obligations of the states on whose territory they reside or transit. Additionally, the paper aims at analysing in which way legal status of these categories of migrants is regulated in Serbia, in order to notice if it is in compliance with the international standards and if it provides appropriate legal basis for the treatment and protection of the mentioned categories.

The objective of this paper is to explore the possibility of an external debt of the Republic of Serbia in terms of its export potential. The regression analysis data was conducted for the period 2001-2012 years in two cases: (i) for evaluation equation of export demand and the evaluation equation interdependence of the GDP and (ii) the real effective exchange rate in the Republic of Serbia. The results show that, with real rates of economic growth in the country (ranging from -1.8 to 3%) and the real rates of economic growth in the countries where the Republic of Serbia exports (ranging from 0.2 to 2%), the external debt can be in the range between -0.43% for 2.09% per annum. This means that the share of foreign trade deficit in the GDP in the Republic of Serbia, with the rate of the GDP in these intervals, bold move between  -0.43 to 2.09% per annum, and not to increase the share of external debt in the GDP.

Transformation towards a social order based on neoliberal values in the states of east Europe has resulted in most cases in the harm for Orthodox-Christian communities. The basic thesis is that neoliberalism represents the value negation of Orthodox Christianity, due to which its universalization is characterized by a militarized approach. The examination of this hypothesis includes the analysis of the consequences of the universalization of neoliberalism in Orthodox Christian communities and in the international system. The obtained results indicate that neoliberalism requires the institutionalization of autonomous individual wills and their associations, which undermines value foundations of Orthodox Christian societies. The findings represent sufficient ground for concluding that violent imposing, even at the cost of destruction of traditional societies, is an immanent characteristic of the implementation of rigid neoliberal value system in Orthodox societies.

In this paper, we analyze the appropriate regulatory framework of the European Union which is related to the issue of the scope of trade mark, i.e. its application in practice, through appropriate judgements of the Court of Justice of the European Union. More particularly, the focus of the analysis is on the factors on the basis of which the scope of trade mark as a subjective right is determined, i.e. the limits of protection acquired by the concrete trade mark. In that sense, this paper will aim to provide a detailed view of, primarily, the concept of likelihood of confusion which represents the key element for determining the scope of trade mark as a subjective right, through the view of the individual elements from which it consists, i.e. on the basis of which the existence of the mentioned likelihood is determined in each concrete case.

In an attempt to reform the existing system of physical education, whilst following the model of education that saw physical education as a vital element in a wider process of physical education, the French pedagogue, baron Pierre de Coubertin, established a social philosophy of Olympism, based on a moral aspect of Ancient Greek sports education. By defining new principles of physical education, de Coubertin's philosophy was founded on the concept of unity between physical and moral development which is seen as a formative factor in character development. The purpose of this work is to define the origin and characteristics of this process of development and promotion of the Olympic values, while pointing out the importance of implementing the concept of Olympic education in formal educational institutions and their teaching programs, which is one of the main educational goals of the Olympic movement worldwide.

The aims of the research include determining the difference in specific forms of midlife crisis manifestation (the Marmor Тheory) as well as the type of deep psychological changes occurring in individuals (the Levinson Тheory) during midlife crisis among the scores of subjects of different ages and gender. The following instruments were used: the Midlife Crisis Scale, the Sex-Role Inventory, the adapted Loyola generativity scale, the adapted scale of preferred aloneness, and a list of the subjects’ basic biodata.The sample included 600 respondents of which 200 were middle-aged, 200 were younger and older. The results demonstrated a difference in individual experiences and behaviors, characteristic of midlife crisis manifestation in individuals.To determine the difference in the degree of prominence of certain variables between the groups of subjects the following tests were used: the Mann-Whitney U-test and Kruskal Wallis test. The results show that the mechanism of denial with overcompensation is most pronounced between 25 and 30 years (χ2 = 167,810, df = 10, p <0.001), decompensation (χ2 = 44.524, df = 10, p <0.001) and the mechanism of denial with escape are most pronounced between 50 and 54 years (χ2 = 160,904, df = 10, p <0.001), while creative and successful confrontation with crisis is most pronounced between 60 and 64 years (χ2 = 196,810, df = 10, p <0.001).That means that the Marmor’s theory is adequate when analyzing external manifestations of midlife crisis, but that the Levinson’s theory needs to be revised when determining the boundaries of occurrence and the process of deep internal changes characteristic of this crisis. More precisely, this suggests that finding a new balance between masculinity and femininity (χ2=237.898, df=10, р<0.001), youth and old age (χ2=379.456, df=10, р<0.001), life gains and losses (χ2=40.136, df=10, р<0.001) and closeness and separation (χ2=27.919, df=10, р<0.001) is a long-term process and that most people, much later in life, become really aware of changes that took place in structure and internal dynamics.

Published: April 2020

In the modern business environment risk management has become a key assistant to enterprise management. Considering that, supply chain management, as part of enterprise management, cannot ignore the risks and the need for implementation of an adequate risk management strategy. Supply chain, as well as inter-organizational network, is the source of competitive advantage. However, inadequate risk management within a supply chain can lead to interruptions of the chain and to the lack of results at the level of the whole supply chain, as well as at the level of individual partners. Upstream supply chain represents the part of supply chain from suppliers to producer. The objective of this paper is to analyse how and to what extent the structure and the number of partners in this part of the supply chain influence (increase or decrease) supply chain vulnerability. The authors analyse the factors which most commonly affect to upstream supply chain and threaten its functioning. By analysing the supply chains from different area, the authors suggest that the size of the supplier's base can be treated as the resistance factor, but also as a factor of vulnerability.

Authors: Kovalev Vladimir A.
Published: April 2020

Introduction. Driving piles in drilled wells are a new trend in pile foundation engineering. Further research and development are devoted to the improvement of structural and process diagrams of these piles in order to increase the bearing capacity mainly on their side surface, mainly in weak clay soils.

Materials and Methods. The options of flow and process diagrams of driving piles in perforated (penetrated) wells in various soil conditions are studied taking into account the existing regulatory documents and earlier developments on increasing the bearing capacity of driving piles in perforated (penetrated) wells.

Results. The main process operations of the driving piles installation in the soil conditions under consideration include perforation (penetration) of the well with a casing with a loose puncher shoe to the base layer of the soil; formation of a well (cavity) in the base layer of the well by means of immersion of the puncher shoe; installation of a shoe reamer in the puncher shoe and formation of a spread foundation made of hard soil material above; immersion of a casing pipe with holes outside the pipe casing; filling of the casing with hard and bulk soil material; removal of the casing and driving (immersion) into the pipe casing of the precast concrete pile filled with bulk soil material with simultaneous formation of additional local broadening and possible compacted soil zones on the sections of holes along the outer contour of the pipe casing.

Conclusions. The proposed structural and process diagrams of driving piles in perforated (penetrated) wells allow to significantly expand the scope of their application in terms of soil conditions, increase the side surface bearing capacity of piles and reliability of the construction of the types of foundations under consideration.

Published: April 2020

Introduction. Requirements for mineral based plasters are divided into two groups: technological and performance properties. Plasticity and ease of application are attributed to the technological properties. This determines the requirements for rheological characteristics and, first of all, for the thixotropy of mixtures. The technique is developed and tested on plaster compositions based on clay-gypsum binder which belongs to the category of local binders. Russia has significant reserves of this raw material, but at present it is not used industrially. The main reason is the lack of a scientifically based theory of hardening of the clay-gypsum binder and the formation of its properties without and with modifying additives. The purpose of this research is to develop the composition and technology of application of interior plaster compositions based on stabilized binder.

The methodology of studying the rheological properties of dry plaster mixtures based on clay gypsum for interior work and wet rooms is presented. The study of the rheology of clay gypsum mixtures is carried out for the first time, it determines scientific novelty. Recommendations for the use of clay gypsum plaster mixtures determine the practical significance of the research.

Materials and methods. Methods of evaluation of thixotropic properties of plaster mixtures based on clay-gypsum binder in laboratory environment are realized.

Results. The valid intervals of the water-cement ratio are established which ranged from 0.46 to 0.50, determined by the limiting shear stress and the actual sliding from the vertical wall.

Conclusions. The possibility of using a clay-gypsum binder in dry plaster mixtures for interior decorative works in the premises, in particular, confirmed by research. It allows us to assess the actual adhesion of plaster coatings to the concrete based surfaces and to brickwork.

Published: April 2020

La avicultura ha sido una de las producciones pecuarias de mayor importancia en Colombia y el mundo, así como uno de los sectores más dinámicos y prometedores en Latinoamérica; actualmente la industria de aves ponedoras consta de diversas alternativas de cría y explotación, siendo el método intensivo en jaula uno de los más utilizados por la eficiencia productiva al operar en una alta densidad de alojamiento, sin embargo, este éxito se ha logrado a costa de la salud y bienestar de los animales implicados en la obtención del huevo. Como alternativa, la producción en pastoreo libre con gallinas de raza criolla se encuentra en auge tanto por la creciente demanda del huevo de campo, como por el interés de la sociedad en el bienestar de las aves productoras. Adicional a esto, se han encontrado gran cantidad de ventajas de este sistema frente a otros, como lo son un ambiente libre de estrés con la libertad de expresión del comportamiento natural de los animales, reducción de problemas comportamentales como agresividad mutua o temor al encargado, menores costos de producción, mejor nutrición al aumentar la cantidad y calidad de los recursos alimenticios disponibles, entre otros. A pesar de estos beneficios, cabe mencionar que la forma de cría de la gallina no implica grandes diferencias en la composición nutricional del huevo. Se debe tener en cuenta, que un correcto proceso de producción, en cualquiera de los sistemas mencionados, garantiza la calidad nutritiva y seguridad del huevo para su consumo. El presente artículo se centra en la avicultura de gallinas ponedoras en pastoreo libre con énfasis en su viabilidad económica y la exploración de sus beneficios y ventajas sostenibles frente a sistemas intensivos.

Authors: Cuaspa-Benavides Jaime Andres , Guerrero-Bastidas Daniel David , Burgos-Arcos Alvaro Javier
Published: April 2020

La acuicultura tradicional se desarrolla de manera inapropiada, en algunos casos sin tener en cuenta las afectaciones al medio ambiente como la eutrofización, introducción de compuestos químicos en los cuerpos de agua y su uso desmedido; por lo tanto, el acceso a recursos naturales cada vez es más limitado. Por otra parte, la agricultura se basa en el uso de fertilizantes e insecticidas que ocasionan el deterioro del suelo y del ambiente, acumulándose directa o indirectamente en la tierra y agua, por esta razón se requiere alternativas productivas sustentables que garanticen la conservación del ambiente, obteniendo ventajas de impacto ambiental positivo. La acuaponía actualmente tiene éxito como sistema de innovación en producción orgánica, por la obtención de productos agrícolas sin suelo en la producción de frutas, verduras y carne de pescado de excelente calidad nutricional; sin contaminantes de descarga, donde se fusionan tres sistemas biológicos diferentes: peces, plantas y bacterias nitrificantes, aprovechando los compuestos nitrogenados de los residuos del alimento y la materia orgánica de los efluentes de la acuicultura. En el presente trabajo se realiza una revisión sistemática de los sistemas acuapónico como una alternativa sustentable de producción de alimentos orgánicos.

One More Time on the Islamization of Indonesia
Authors: Gadzhiev T. F.
Published: April 2020

The paper is devoted to the complicated problem of islamization of Indonesia. The author describes mainly the three most important theories related to this long cultural process. The ﬁrst theory, elaborated by W. F. Stutterheim, Chr. Snouck-Hurgronje and L. W. van den Berg, derives Indonesian Islam from Gujarat. Close contacts with India as well as some archeological funds witness for this version. The second theory, (Indonesian scholars maintain it mostly), explains Islamization by activity of Arab sailors. The most known of its partisans is Indonesian theologian Haji Abdul Malik Karim Amrullah or Hamka. The third theory looks as modiﬁcation of the second, in this case not Arab, but Persian-originated sailors are considered as preachers. Namely its defenders (H. Jayadiningrat and U. A. Hussein) apply culturological approach while arguing for Persian inﬂuence. The paper also deals with the ﬁrst period of spreading of Islam through the territory of modern Indonesia. The special attention is paid also to some signiﬁcant features of Indonesian Islam.

The discourse as the process of linguistic activity, as the complicated communicative phenomena is broadly studies in the works of Russian as well as European scholars. The paper deals with the short outline of works, which are devoted to the study of theme of global power of discursive communication. In the circumstances of human interaction the information is not only a mode to interact; it is also a factor, which unites people, lets it develop and inﬂuence mutually. This paper deals with discursive practices of Islam, describes problems of false understanding of Islamic theology. The author strives for rethink some Islamic concepts, because of being aware of necessity to translate them into the modern language. Some important terms, as it was shown, are incorrectly translated. It requires meaningfulness and responsibility while speaking about Islam and for Muslims.
Tuberculosis y una Gemella spp: Una combinación indeseable
Authors: Buitrago-Gutiérrez Alberto Fernando , Veronesi-Zuluaga Luz Amaya , Parra-Guacaneme Angie Viviana
Published: April 2020

El género Gemella spp corresponde a cocos gram positivos, anaerobios facultativos, catalasa negativos, no móviles y no formadores de esporas, usualmente comensales de la cavidad oral, que no suelen ser patógenos en pacientes inmunocompetentes. Sin embargo, puede comportarse como germen oportunista en pacientes inmunosuprimidos o con otros factores de riesgo como mala higiene dental, cirugía gastrointestinal, enfermedades metabólicas entre otras, y se asocia con endocarditis, meningitis y en menor medida compromiso pulmonar. La información respecto a la susceptibilidad antimicrobiana es limitada y se asemeja a la de S viridans, por lo que la penicilina y ampicilina son los medicamentos de elección, sin tener claridad en cuanto a duración del tratamiento, usualmente considerando llevar a 4 semanas o hasta el drenaje de la colección. Éste reporte de caso describe una paciente con tuberculosis en tratamiento, que desarrolla una infección invasiva con documentación de empiema y bacteriemia secundaria por Gemella morbillorum, representando la asociación poco común de ésta infección bacteriana con tuberculosis.
Sonic Conversations for Double Bass, Berimbau and Sámi Joik: Shaping Identity in the Third Space
Authors: Nathan Riki Thomson
Published: April 2020

This exposition presents, unpacks and discusses the effects of intercultural dialogue and collaboration on the formation of an individual personal artistic identity, through the lens of two musical duets. These artistic research case studies are centred around the author in dialogue with a Brazilian berimbau player and a Sámi singer, which act as focal points to examine how intercultural dialogue and collaboration can impact on the formation of a personal artistic identity and how the third space emerging from a transcultural dialogue can be a catalyst for new musical discoveries. In addition, I consider the kinds of musical and communication skills that are needed to co-create music in a transcultural context and which kinds of ethical issues arise.

The core thread of discussion and argumentation is centred firstly around the idea that by placing oneself in diverse and unknown musical environments and engaging in dialogue, a dynamic third space emerges, which holds within it the opportunity for new elements and approaches to surface and take shape in unexpected ways. And secondly, I propose that searching for points of resonance with the world around us may be crucial in the creation of meaning and the formation of a personal artistic identity. Although the practice of music making is at the core of this research, the work is viewed with a wide-angle lens, acknowledging findings that point to the importance and potential benefits of increasing intercultural dialogue, understanding, collaboration and resonance at all levels of society. Discoveries also emerge within the areas of extended instrumental techniques and an expanded sonic palette for the double bass, as well as the creation of new music.

This exposition zooms in on two examples from my complete artistic doctoral project at Sibelius Academy, Uniarts, Helsinki, namely the two sonic conversations for double bass and berimbau, and double bass and Sámi joik.

In this study, micromorphology of an involucral bract and inner and outer
dimorphic cypselae of the relict Amphoricarpos elegans, endemic from western
Caucasus, is examined using a scanning electron microscope (SEM) and
presented here for the first time. The middle involucral bract is nearly
glabrous, with a reticulate-rugulose surface and an oblong-obtusate mucro.
Both cypselae exhibit similar features, viz., narrowly oblong-cylindrical or
obovate shape with more or less conspicuous longitudinal ribs, an adaxial
detachment area, an asymmetrical carpopodium, absence of a pericarp crown
and a barbate-aristate pappus made up of narrow, subulate, basally smooth
and apically barbate bristles. However, some differences are evident. The
outer cypsela is glabrescent and flattened, with an obscure outline of
epidermal cells lacking an end wall and with a sunken periclinal surface and
striatereticulate structure. Also, the outer cypsela has two entire, narrow,
lateral wings, rounded above; and less numerous pappus bristles in one row.
In contrast to this, the inner cypsela has a distinct outline of the
epidermal cells, which are rod-shaped with a short acute end wall, a swollen
periclinal surface and reticulate structure. The pappus of the inner cypsela
possesses many more bristles organised in two rows (a biseriate pappus).
Also, slightly pentagonal or round nectary remnants are found in the centre
of the upper part of the inner cypsela. The taxonomic value of the analysed
characters is briefly discussed.

Authors: Inceer Huseyin , Kalmuk Nursen
Published: April 2020

In this study, we report genome size (C-values) estimated using flow
cytometry for 18 taxa of Asteraceae from Turkey, 17 of which are here
assessed for the first time. The studied taxa belong to the genera Achillea
(one species), Anthemis (one subspecies), Tanacetum (four taxa) and Crepis
(12 taxa). Additionally, chromosome numbers of nine taxa of Crepis are
provided, four counts being new reports and the remainder confirming
previous data. The 2C-values of the studied taxa range from 2.08 to 11.06
pg, which represent more than fivefold variation. The systematic and
evolutionary significance of genome size is discussed within the framework
of the results obtained in this study.

Published: April 2020

Arbutus unedo is a species mainly used for landscaping purposes and lately
for honey production. Its antioxidant characteristics have also been a
subject of of research interest. The germination of pollen grains freshly
collected from flowers was tested in vitro, and 30% sucrose gave the highest
pollen germination. Subsequently, three growth regulators belonging to the
categories of gibberellins and brassinosteroids [24-epibrassinolide (Ebl)
and 22S,23S-homobrassinolide (Hbl)] were added to the growth medium singly
or in double combinations (gibberellin + brassinosteroid), and the petri
dishes were kept for 24 hours at 26?1?C. The results showed that the highest
germination rates were obtained from treatments with 0.01 ppm Hbl (45.47%)
and 0.001 ppm Hbl (26.74%). They were followed by treatments with 0.001 ppm
Ebl, 25 ppm GA3 and 0.1 ppm Ebl. As the concentration of GA3 increased, the
germination rate declined considerably. Statistical analysis of the combined
treatments showed that combinations of growth regulators lowered the
germination rates compared to their individual application. Moreover, action
of the lowest GA3 concentration (25 ppm) best matched the effects of
brassinosteroids, and increasing the GA3 concentration in combined
treatments did not improve germination. The highest germination was obtained
with 0.1 ppm Hbl, followed by all Ebl treatments. Brassinosteroids might be
an inducer of pollen germination in plants depending on their type and
concentrations. When individually included in the growth medium, the extent
of this induction was greater with the homobrassinolide than with the
epibrassinolide. Their interactions with gibberellins are shown to be mostly
dependent on the concentration of gibberellic acid used. The tested
epibrassinolide was more consistent than the homobrassinolide in maintaining
higher germination levels. The findings of this study indicate that
gathering more information from studies involving other plant species is
needed to clarify the role of brassinosteroids in in vitro and in vivo
germination.
Real exchange rate and trade balance in Turkey: Evidence from heterogeneous panel data
Authors: Kaya Ahmet
Published: April 2020

In this study, the effect of real exchange rate on bilateral trade balance between Turkey and its 25 main trade partners is investigated for the period of 1996-2015 with heterogeneous panel data techniques. Trade balance model is estimated by using Mean Group (MG) estimator, which allows parameter heterogeneity, Common Correlated Effects Mean Group (CCEMG), and Augmented Mean Group (AMG) estimators, which both allow cross-section dependency and heterogeneity. Results indicate that the real exchange rate elasticity of the trade balance ranges between -0.40 and -0.45 and Marshall-Lerner (ML) condition is valid for Turkey. According to the results, the foreign income elasticity of trade balance ranges between 1.54 and 2.84, while for domestic income elasticity, it is found between -0.75 and -1.38. Country-specific results show that ML condition is valid for the USA, Belgium, Spain, Switzerland, Romania, and Russia at the bilateral level according to both CCEMG and AMG estimators.

Published: April 2020

The KISS1 / KISS1R signaling system can serve as a regulator of metastasis of tumors and is a potential prognostic marker of tumor processes. The action of kisspeptin10 on the Era-negative non - malignant breast epithelial cells or KISS1R expression in these cells can induce passage to the mesenchymal phenotype and to stimulate the invasiveness. The level of expression of KISS1 in remote breast cancer metastases is lower than in the primary tumor: methylation of the KISS1 promoter may be one of the reasons for the decrease of the expression of mRNA and KISS1 protein in the cells of breast cancer metastases in the brain. The clinical significance of KISS1 lies in the prediction of involvement in the neoplastic process in the lymphnodes. Features of expression of KISS1 / KISS1R in Era-positive tumors give hope for the emergence of new approaches to the treatment of these tumors. The level of KISS1 expression can serve as a molecular marker predicting the quality of tumor response to Tamoxifen therapy, especially in postmenopausal women.
Pathological changes of myocardium in the model of chronic renal insufficiency at application of low-protein diet
Authors: Shved N. V , Baykov V. V
Published: April 2020

Myocardial damage in patients with chronic renal failure histologically manifests as hypertrophy of cardiomyocytes, intramyocardial artery walls, development of diffuse sclerosis and a change in the number of capillaries. One of the components in the complex treatment of this category of patients is a low-protein diet, however, to date there is no data on the effect of a low-protein diet on structural changes in the myocardium. The aim of the work was to assess the effect of low protein diet on myocardial structural changes in the experimental model of chronic renal failure. To reproduce the experiment of chronic renal failure, a standardized 5/6 nephrectomy model was used in wistar rats. To determine the effect of a low-protein diet on structural changes in the myocardium, two types of diet were used - a standard one and a low-protein diet (Ketosteril). The animals were sacrificed 4 months after nephrectomy. For a comparative assessment of the effect of low-protein diet on structural changes in the myocardium, histological methods of investigation and morphometry were used. The use of low-protein diet was accompanied by a less pronounced violation of biochemical blood parameters (creatinine, urea, calcium, phosphorus), as well as maintaining normal blood pressure, myocardial mass and left ventricular wall thickness. Histologically, this was manifested by a decrease in the severity of dystrophic changes in cardiomyocytes, the degree of their hypertrophy, a decrease in the area of nuclei, and a decrease in the nuclear-cytoplasmic ratio. Indices of perivascular and diffuse sclerosis were lower compared with the control group. Also, when using low-protein diet in animals with a chronic renal failure model, a decrease in the total cross-sectional area of capillaries was noted with an increase in their number in comparison with animals of the control group. Thus, the use of a low-protein diet in an experimental model of chronic renal failure has a cardioprotective effect by reducing the severity of uremia and stabilizing biochemical parameters.

The giant cell tumors of maxillofacial bones include several barely differentiable diseases with diverse prognoses. A case of a giant cell tumor in an 18-year-old man is described. Clinical, instrumental and laboratory examination did not allow to establish an accurate diagnosis. Molecular genetic test by New generation sequencing (NGS) of tumor tissues and blood identified mutation p. 1424 C> A; p.Pro475His in the SH3BP2 gene, previously described in patients with the so-called cherubism, that determined the tactic of treatment. Carrying out an oncogenetic study allows the differential diagnosis of such morphologically similar conditions with a giant cell component as a multiorgan form of fibrous dysplasia, reparative granulomas, Noonan syndrome, Sturge-Weber-Crabbe syndrome, juvenile ossifying fibroma.
