Purpose: Vascular access surveillance in hemodialysis is today an important challenge for nephrologist. Low blood flow is a risk factor for development of thrombosis of native fistula or graft.
The aim of the study is to evaluate the correspondence between flow measurement by thermodilution and Color Doppler, and to identify flow rate values using the Blood temperature monitor (BTM) method in the case of stenosis.
Methods: We evaluated 29 patients on chronic hemodialysis. The evaluation of blood flow with BTM were performed during the first hour of the hemodialysis session. All patients underwent a color doppler of vascular access within 10 days from the BTM measurements.
Results: The mean vascular access flow calculated with BTM resulted 1142 ± 700 ml/min and there was a correlation with color doppler data 1199 ± 644 ml/min (p=0,0001 r=0,829). The flow of patients with hemodynamically significant stenosis was 332 ± 92 ml/min with a minimum value of 270 ml/min and a maximum value of 440 ml/min.
Conclusion: the correspondence between thermodilution and color doppler support the implementation of intradialitic evaluation of the vascular access blood flow with the BTM method. Thermodilution allows to identify earlier patients with high risk of vascular access failure and the need for further diagnostic and therapeutic investigations.

Activation of the hypothalamic-pituitary-adrenal (HPA) axis is important for maintenance of homeostasis during stress. Recent studies have shown a connection between the HPA axis and adipose tissue. The present study investigated the effect of acute heterotypic stress on plasma levels of adrenocorticotropic hormone (ACTH), corticosterone (CORT), leptin, and ghrelin in adult male rats with respect to neonatal maternal social and physical stressors. Thirty rat mothers and sixty of their male progeny were used. Pups were divided into three groups: unstressed control (C), stressed by maternal social stressor (S), stressed by maternal social and physical stressors (SW). Levels of hormones were measured in adult male progeny following an acute swimming stress (10 min) or no stress. ELISA immunoassay was used to measured hormones. The ACTH and CORT levels were significantly increased in all groups of adult progeny after acute stress; however, CORT levels were significantly lower in both neonatally stressed groups compared to controls. After acute stress, plasma leptin levels were decreased in the C and SW groups but increased in the S group. The data suggest that long-term neonatal stressors lead to lower sensitivity of ACTH receptors in the adrenal cortex, which could be a sign of stress adaptation in adulthood. Acute stress in adult male rats changes plasma levels of leptin differently relative to social or physical neonatal stressors.

It is precisely in the course of adjusting the activities of these subjects, the main task of state regulation of the bankruptcy institute is the formation of such conditions for the functioning of the national economy, which will reduce the risk of doing business for all its entities and promote the internal reorganization of its structure in accordance with the requirements of global transformations. The system of indicators describing the situation in a certain area of ​​the functioning of national economic entities allows us to determine, directly or indirectly, the effectiveness of the bankruptcy institute at the macro-level. To analyze the impact of each of the factors on GDP, a sensitivity analysis was conducted according to which input data X were recorded at the values ​​of 2018 and alternately changed by 10%. For each such change, GDP was calculated as compared to the model value for 2018. As a result of the calculations, the most sensitive factors were identified and features of the functioning of the bankruptcy institute in the Ukrainian economy were identified. The main provisions of a state policy aimed at increasing the functional effectiveness of the bankruptcy institute are formulated. First of all, it is necessary to promote the country's position in the Doing business rankings, as well as the Indexes of Economic Freedom and Corruption Perceptions. On the other hand, an annual growth of the inflation index of around 10% and the level of the fiscal tax burden will also have a positive effect on GDP dynamics.

Authors: Lima Josenice Cláudia Moura de , Stella Paulo Rogério 
Published: April 2020

O presente artigo é um recorte de uma Dissertação de Mestrado e se propõe a analisar uma tirinha produzida por uma estudante de uma turma de ensino médio, que foi resultado de um processo de discussão em sala de aula de língua inglesa acerca de questões relativas aos gêneros como construções identitárias. Seguindo a perspectiva dos estudos bakhtinianos, observaremos a circulação de valores, entendidos como diferenças de gêneros em seus discursos. Para Volochinov (2017), nas interações envolvendo locutores e interlocutores circulam valores sociais e históricos presentes no ambiente onde se encontram esses interlocutores. E esses respondem ativamente a esses valores, concordando ou discordando com eles. Para tanto, este artigo divide-se em três partes. Na primeira, discutiremos sobre a questão da ideologia de gêneros na contemporaneidade. Na segunda, trataremos do recorte metodológico do trabalho de pesquisa de viés qualitativo. E na terceira e última seção, apresentaremos uma produção de uma estudante sobre a qual refletiremos acerca da questão da ideologia de gêneros com base nos valores trazidos por ela.PALAVRAS-CHAVE: Gêneros; Língua Inglesa; Linguística Aplicada.

Published: April 2020

O objetivo deste artigo é apresentar um recorte da pesquisa desenvolvida com a linguagem de idosos moradores na Instituição de Longa Permanência para Idosos – ILPI, em Vitória da Conquista, Bahia, Brasil. Os dados foram coletados a partir de filmagem e gravação dos idosos em meio a situações enunciativo-discursivas, considerando a história dos sujeitos e seus atravessamentos, bem como a condição de produção desses discursos e o conceito de dado-achado (COUDRY, 1988). Neste artigo, apresentamos a análise de dados referentes ao silêncio que ocorre em sessões com uma das moradoras dessa ILPI. Para tanto, recorremos ao pensamento sobre o silêncio a partir de diferentes áreas, como: da Música, da Filosofia, da Psicanálise e da Análise do Discurso, enquanto disciplina de entremeio da Linguística, com conceitos relevantes para este trabalho. Apesar de serem áreas distintas, observamos que compartilham para o fato que o silêncio não é o zero, vazio, o que nos leva a interpretâ-lo como sentido. Assim, consideramos, por meio das análises, que o silêncio permeia cada signo e se infla de sentido, e que, quando está só, por si só, significa, possibilitando o sujeito institucionalizado rememorar momentos de dependência, (re)elaborar seus desejos, suas respostas.

Authors: Kotov-Smolenskiy A. M. , Klochkov A. S. , Khizhnikova A. E. 
Published: April 2020

Background. Personal degrees of motor activity frequently is a determining factor of human health and longevity. A sedentary lifestyle is a precondition for the development of many diseases and adversely affect the harmonious physical development of a person. The result of poor physical fitness is reduced movement coordination and the balance function, which can cause falls and injuries. Today, it is not always possible for healthy people of working age and adolescents to organize physical education events, however, modern rehabilitation technologies can serve as a solution to this issue.
Aims analysis of the effectiveness of balance training physical exercises performed in a virtual environment, in people with low physical fitness.
Methods. In the experimental group, a set of physical exercises were performed in a virtual environment, in the control group in a real environment with additionally created pedagogical conditions aimed at the position of greater instability using gymnastic pads of different stiffness, and foam material bar.
Results. The study involved 20 female volunteers (aged 16 to 17 years), who were divided into two equal groups, comparable in age (р 0.05). A statistical analysis of the data obtained at the end of the training course showed that experimental and control groups in the maximum torso deviation in the Romberg instrumental test (p = 0.11) when standing on toes with eyes closed (p = 0.24), and the stability time in the Bondarevsky test (p = 0.07) are no longer significantly different.
Conclusions. Performing physical exercises with visual support for biological feedback in a virtual reality system can contribute to the intensification of the learning process, have a beneficial effect on the prevention of a sedentary lifestyle, and also contribute to the training of the balance function, as one of the most important human abilities that determine its motor capabilities.
Higher education challenges in Brazil
Authors: Sampaio Helena , Carneiro Ana Maria , De Andrade Cibele Yahn , Knobel Marcelo 
Published: April 2020

Following the international trend, higher education in Brazil is going through important transformations, including the widening of access and the growth of enrollment numbers. From the beginning of the century the number of enrollments tripled, reaching more than eight million students in 2015. Here we discuss some factors that converged to cause this expansion, and we try to indicate the main challenges of the Brazilian higher education system. We begin with a brief analysis of the federal program of loans for students enrolled in private institutions, and the program for increasing the number of places in public institutions. We then point out, in some detail, the current challenges that the Brazilian higher education system faces: i) maintenance of the pace of growth of enrollments; ii) improvement of efficacy, with a reduction of dropouts and a larger number of graduates; iii) development of access mechanisms; and iv) awareness of the diversity of the offer of post-secondary education in the country. Although these challenges are also present in most of the systems that made a move towards the democratization of access to higher education, in Brazil these challenges are faced in the context of a wide privatization and commodification of this level of education, together with a strong economic and fiscal crisis. Besides that, there is a rather strong valorization of a unique model of higher education based on the research university, which in fact corresponds to a small part of the national system.

Demystifying research methods: everyday experiences as socio-cultural co(n)texts for effective research methods in teaching and learning in institutions of higher learning in Africa
Authors: Banda Felix , Banda Dennis 
Published: April 2020

The aim of the paper is to demonstrate how everyday knowledge can be incorporated into the classroom practices of institutions of higher learning to inform inclusive outcomes for linguistically and culturally diverse students. Using a metaphor of a marketer’s everyday interrogation of market conditions, a postgraduate guide to proposal writing and the funds of knowledge socio-cultural framework, we illustrate how forms of everyday and school knowledge can be used concurrently in the construction of socially responsive dialogic pedagogy. We argue for scholarship of teaching and learning (SOTL) in the South in which knowledge and theory generation is not a preserve of English only, but more so, of the complex interactions between English and the multiplicity of languages that students bring to the classroom. We conclude that SOTL in the South needs to be founded on the transfiguration of everyday knowledge and formal academic knowledge to facilitate the production of new and more powerful knowledge in multicultural postcolonial society. This would allow for inclusive pedagogy that caters for diversity in classrooms, and activity-based teaching and learning, networking students’ experiential, community/home and formal academic knowledge in the construction of new and powerful knowledge.
