Abstract
Polyomaviruses are common viruses that induce various infections in many mammalian species, including humans. The best-known viruses of this kind are BKV and JCV. The aim of the study was to analyze the incidence of infection caused by JCV in a group of patients after kidney or bone marrow transplant, and to analyze JCV genetic diversity in post-transplantation recipients. The study group included 81 patients after kidney transplantation treated in the Independent Public Teaching Hospital No 4 in Lublin and a group of 24 patients after marrow transplantation from the Children's Clinical Hospital of Lublin. The research material included 105 DNA probes from urine samples that were tested via the PCR method for the presence of JCV genetic material. Amplification products were separated in agarose gel, positive PCR products were subjected to purification and the pure product was sent to sequencing. Pearson's chi-square test was used to investigate the relationship between the prevalence of JCV viruria and study group and gender. Statistical significance was defined as p < 0.05. A JCV positive result was discovered in 27.6% of all samples. In the group of adults, 34.6% were positive, while in children, this was 3.4%. Among all patients, only 8 women were infected with the JC virus, while 21 men were. We saw that the incidence of infection caused by the JC virus increases with age. Moreover, JCV DNA is more frequently isolated from men than from women. JCV infections are also a more common cause of infections in patients after renal transplantation than in bone marrow transplant patients

AbstractReceived 08 November 2017 Accepted 15 February 2018 The incidence of community-acquired UTIs due to extended-spectrum beta-lactamase (ESBL) producing E. coli isolates, has increased worldwide and is considered a great problem in the treatment of infections. The aim of this study was to determine the prevalence of ESBL producing E. coli isolates in urine samples of outpatients in Babol, North of Iran. A total of 3 699 urine samples from outpatients referred to Yahyanejad Hospital, Babol, Iran, were collected during 15 months, from March 2016 to June 2017. The samples were processed for bacterial culture using conventional methods, while antimicrobial susceptibility testing for E. coli isolates was performed by the disc diffusion method. The prevalence of ESBL producing E. coli isolates were assessed by Double-Disc tests. Of 3699 tested sample, 201 samples showed the growth of pathogens and among them, 106 isolates (52/7%) were E. coli. The rate of ESBL producing E. coli isolates was 25/4%.The majority (81/5%) of the isolates were from females. High percent resistance was found against ceftazidime, cefotaxime, ceftriaxone, cefixime and ciprofloxacin, ranging from 61-100%, while the highest percent susceptibility was seen to meropenem, piperacillin- tazobactam (100%), followed by nitrofurantoin and amikacin (91%). The high prevalence of ESBL producing E. coli isolates from outpatients calls for the need to aware of this increasing resistance between uropathogens and update bacterial susceptibility data and to set up our empirical therapy accordingly.

Comparison of the Overall Motion Correlation Times of Several Mammalian Serum Albumins in Dilute Solutions Determined on the Basis of Maxwell Effect and the Debye-Stokes-Einstein Equation.
Authors: Monkos Karol 
Published: June 2018

Abstract
One of the rarely used ways of determining the overall motion correlation time of proteins is method based on the Maxwell effect. This effect consists in the appearance of a stimulated birefringence in liquids or solutions and induced by the mechanical force like shear stress in a streamline flow. To determine the overall motion correlation time for protein in dilute solution is sufficient to know the molecular mass and the ratio of the principal axes of protein, and an intrinsic viscosity. The intrinsic viscosity has been measured using an Ubbelohde-type capillary microviscometer immersed in a water-bath controlled thermostatically in the range from 5°C to 45°C for six mammalian albumins. To check the influence of solution pH on the overall motion correlation time the intrinsic viscosity value of the human serum albumin in solutions at the isoelectric point and beyond of it was measured. The thus obtained correlation times were compared with the times determined on the basis of the Debye-Stokes-Einstein equation.

Abstract
Magnetorheological fluid (MRF), an intelligent material with controllable properties, has been widely used because of its unique magnetorheological effect and excellent rheological properties. Therefore, studying the preparation and performance of the system is crucial. First, the related equipment and raw materials were prepared at four volume percentages of MRF specimens—20 %, 33.3 %, 45.9 %, and 58.9 %. Then, on the basis of the pull method principle, we built a stress-testing device for an MRF yield. Furthermore, the yield stress values of the four kinds of MRFs were tested by the yield stress test device. Finally, the effect of temperature on the yield stress of the MRF was investigated. The experimental results show that the yield stress of the MRF decreases with increase of the temperature.
Identidades de gênero e ameríndia. A descolonização do corpo em Robert Lalonde e Paulo Jacob
Authors: Carvalho de Matos Marques Karina 
Published: June 2018

Este artigo propõe uma análise comparativa dos romances Le dernier été des Indiens (1982), do escritor quebequense Robert Lalonde, e Tempos infinitos (1999), do escritor manauara Paulo Jacob, ambos partilhando a temática do relacionamento intercultural entre índios e brancos, dentro da esfera amorosa. Nos dois romances, a transformação interior dos protagonistas, em contato com a alteridade ameríndia, está associada a momentos históricos decisivos tanto para a sociedade canadense (Révolution Tranquille, 1959) como para a brasileira (fim da época áurea gomífera, em torno de 1912). Identidades individual e coletiva entram, portanto, em ressonância, buscando afastar-se do legado colonial, ancorado no presente da narrativa. Identidades de gênero e ameríndia também entrelaçam-se em ambos os romances, dentro de um projeto comum de descolonização tanto dos corpos dos protagonistas, como dos corpos sociais regionais/nacionais nos quais estão inseridos, afastando-se do modelo cultural e sexual de dominação do colonizador. Os conceitos de gênero como ato performático (BUTLER) e de “pedagogia nacionalista” (BHABHA) guiarão esta análise de forma a mostrar os efeitos sedimentados das práticas reiterativas colonialistas na base de construção tanto do corpo individual, quanto do corpo coletivo. À luz desses conceitos fulcrais, serão, enfim, observadas as propostas de Lalonde e Jacob para a construção de uma nova identidade quebequense-canadense e amazônica-brasileira, refletindo sobre a instrumentalização, pelo grupo hegemônico, da cultura indígena e do ideal de miscigenação cultural.
Cartografias da Cidade Fantasma Canudos, 120 Anos da Guerra do Fim do Mundo
Authors: Novaes Claudio Cledson 
Published: June 2018

Neste artigo, discutimos a problemática do urbano versus rural no Brasil em narrativas do ciclo canudiano, partindo do olhar paradoxal de Euclides da Cunha sobre a Guerra de Canudos, em Os Sertões. Demarcamos, após 120 do trágico do conflito, as concepções de cidade moderna e liberal positivista em contraponto com os dispositivos da anti-cidade, conceito aqui articulado para a leitura das imagens de resistências dos vencidos, como aquelas dos ressurgimentos simbólicos do arraial destruído pela guerra, pelo fogo e pelas águas. A cartografia crítica do vilarejo sertanejo denominado pelos conselheiristas de Belo Monte é o contraponto ao modelo violento da polis na atualidade, considerando que o fantasma canudiano ainda assusta no espelho dos enfrentamentos cotidianos nas periferias das cidades contemporâneas brasileiras.

Published: June 2018

Background and aims
Based on the foundations of Bandura’s social cognitive theory and theory of triadic influence (TTI) theoretical framework, this study was designed to examine the mediating role of positive outcome expectancy of Internet use in the relationship between social influence and Internet addiction (IA) in a large representative sample of senior high-school students in Taiwan.

Methods
Using a cross-sectional design, 1,922 participants were recruited from senior high schools throughout Taiwan using both stratified and cluster sampling, and a comprehensive survey was administered.

Results
Structural equation modeling and bootstrap analyses results showed that IA severity was significantly and positively predicted by social influence, and fully mediated through positive outcome expectancy of Internet use.

Discussion and conclusions
The results not only support Bandura’s social cognitive theory and TTI framework, but can also serve as a reference to help educational agencies and mental health organizations design programs and create policies that will help in the prevention of IA among adolescents.
