Published: June 2017

Background:Human mast cells (MCs) are long-lived tissue-resident immune cells characterised by granules containing the proteases chymase and/or tryptase. Their phenotype is modulated by their tissue microenvironment. The human uterus has an outer muscular layer (the myometrium) surrounding the endometrium, both of which play an important role in supporting a pregnancy. The endometrium is a sex steroid target tissue consisting of epithelial cells (luminal, glandular) surrounded by a multicellular stroma, with the latter containing an extensive vascular compartment as well as fluctuating populations of immune cells that play an important role in regulating tissue function. The role of MCs in the human uterus is poorly understood with little known about their regulation or the impact of steroids on their differentiation status.The current study had two aims: 1) To investigate the spatial and temporal location of uterine MCs and determine their phenotype; 2) To determine whether MCs express receptors for steroids implicated in uterine function, including oestrogen (ERα, ERβ), progesterone (PR) and glucocorticoids (GR).Methods:Tissue samples from women (n=46) were used for RNA extraction (n=26) or fixed (n=20) for immunohistochemistry.Results:Messenger RNAs encoded byTPSAB1(tryptase) andCMA1(chymase) were detected in endometrial tissue homogenates. Immunohistochemistry revealed the relative abundance of tryptase MCs was myometrium>basal endometrium>functional endometrium. We show for the first time that uterine MCs are predominantly of the classical MC subtypes: (positive, +; negative, -) tryptase+/chymase- and tryptase+/chymase+, but a third subtype was also identified (tryptase-/chymase+). Tryptase+ MCs were of an ERβ+/ERα-/PR-/GR+ phenotype mirroring other uterine immune cell populations, including natural killer cells.Conclusions:Endometrial tissue resident immune MCs have three protease-specific phenotypes. Expression of both ERβ and GR in MCs mirrors that of other immune cells in the endometrium and suggests that MC function may be altered by the local steroid microenvironment.

Published: June 2017

Context: The effect of L-arginine on risk factors of cardiovascular diseases (CVD) has mostly focused on western countries. Since cardiovascular diseases is the second cause of death in Iran and, as far as we are aware, there have been no studies about the effect of L-arginine on CVD risk factors, the aim of this trial was to assess the effects of L-arginine supplementation on CVD risk factors in healthy men. Objective: The purpose of this study was to evaluate the effect of low-dose L-arginine supplementation on CVD risk factors (lipid profile, blood sugar and blood pressure) in Iranian healthy men. Design, setting, participants: We conducted a double-blind randomized controlled trial in 56 patients selected from sport clubs at the Isfahan University of Medical Science between November 2013 and December 2013. Interventions: Healthy men received L-arginine supplementation (2000 mg daily) in the intervention group or placebo (2000 mg maltodextrin daily) in the control group for 45 days. Main outcome measure: The primary outcome measures were we measured the levels of fasting blood sugar, blood pressure and lipid profile including triglyceride (TG), cholesterol, LDL and HDL in healthy subjects. It was hypothesized that these measures would be significantly improved in those receiving L–arginine supplementation. at the beginning and end of the study. Results: In this trial, we had complete data for 52 healthy participants with mean age of 20.85±4.29 years. At the end of study, fasting blood sugar (P=0.001) and lipid profile (triglycerideTG (P<0.001), cholesterol (P<0.001), LDL (P=0.04), HDL (P=0.015)) decreased in the L-arginine group but we found no significant change in the placebo group. In addition, the reduction of fasting blood sugar and lipid profile in L-arginine was significant compared with placebo group. No significant changes were found about systolic (P=0.81) and diastolic blood pressure either in L-arginine or placebo group. (P=0.532). Conclusion: The use of L-arginine significantly improved outcomes compared to placebo.

Authors: Rodríguez Esteves Juan Manuel 
Published: June 2017

Los huracanes y otras tormentas tropicales son fenómenos naturales que atraen el interés de las personas en todo el mundo, en especial cuando afectan comunidades costeras. cada año, sobre todo durante la temporada de huracanes, es común leer o ver en los diferentes medios de comunicación los daños provocados por las tormentas tropicales en varios países, ante todo en América Latina y Asia. Para el caso de México, el total de pérdidas económicas asociadas a fenómenos naturales ha ido en aumento. Durante el año 2000 se destinaron 230 millones de dólares (US) para la reconstrucción de la infraestructura afectada por fenómenos hidrometeorológicos, mientras que en el 2013 los daños ascendieron a 4 476 millones de dólares, con un pico durante 2010 cuando se registraron 7 208 millonesde dólares en pérdidas. Por otro lado, del total de daños provocados por fenómenos naturales, el 92 % estuvo asociado a fenómenos hidrometeorológicos, entre los que se encuentran los huracanes y otros fenómenos (SEGOB, 2014). El objetivo de este artículo es analizar los impactos provocados por los desastres asociados a la influencia de los huracanes desde una perspectiva comparativa entre dos fenómenos en particular, el huracán Pauline en 1997 y la tormenta Manuel en 2013, eventos hidrometeorológicos que afectaron el estado mexicano de Guerrero, pero en especial el puerto de Acapulco. una de las conclusiones principales de este estudio se refiere a que no importa solamente la intensidad del fenómeno natural para generar daños en la sociedad, sino que el total de daños también se refiere a los contextos de vulnerabilidad que una sociedad genera con el transcurso de los años.
Cobertura jornalística sobre desastres no Brasil: dimensões sociopolíticas marginalizadas no debate público
Authors: Valencio Norma , Valencio Arthur 
Published: June 2017

Las ciencias sociales pueden proveer a la opinión pública interpretaciones significativas sobre los desastres, toda vez que disponen de los recursos teóricos y metodológicos para identificar y analizar las múltiples dimensiones de los aspectos sociales involucrados. A pesar de esto, sus contribuciones son subestimadas en Brasil por los medios de comunicación que cubren tales tragedias. A través de métodos cualitativos y cuantitativos, este estudio ilustra los aspectos sociopolíticos de las crisis crónicas, que son poco explorados por los reportajes sobre desastres. Esto se presenta en el contexto nacional y, especialmente, en la región sudeste. Las conclusiones revelan que, a pesar de que la crisis aguda aparece frecuentemente en los titulares de las noticias, el contenido de las noticias pierde su calidad narrativa cuando no es considerado el desastre como un proceso social a largo plazo y a gran escala.

Authors: Jam Jafar Eskandari , Noorabadi Milad , Namdaran Nader 
Published: June 2017

AbstractIn this paper, nonlinear free vibration analysis of micro-beams resting on the viscoelastic foundation is investigated by the use of the modified couple stress theory, which is able to capture the size effects for structures in micron and sub-micron scales. To this aim, the gov-erning equation of motion and the boundary conditions are derived using the Euler–Bernoulli beam and the Hamilton’s principle. The Galerkin method is employed to solve the governing nonlinear differential equation and obtain the frequency-amplitude algebraic equation. Final-ly, the effects of different parameters, such as the mode number, aspect ratio of length to height, the normalized length scale parameter and foundation parameters on the natural fre-quency-amplitude curves of doubly simply supported beams are studied.
Identification and Adjustment of Guide Rail Geometric Errors Based on BP Neural Network
Authors: He Gaiyun , Huang Can , Guo Longzhen , Sun Guangming , Zhang Dawei 
Published: June 2017

Abstract
The relative positions between the four slide blocks vary with the movement of the table due to the geometric errors of the guide rail. Consequently, the additional load on the slide blocks is increased. A new method of error measurement and identification by using a self-designed stress test plate was presented. BP neural network model was used to establish the mapping between the stress of key measurement points on the test plate and the displacements of slide blocks. By measuring the stress, the relative displacements of slide blocks were obtained, from which the geometric errors of the guide rails were converted. Firstly, the finite element model was built to find the key measurement points of the test plate. Then the BP neural network was trained by using the samples extracted from the finite element model. The stress at the key measurement points were taken as the input and the relative displacements of the slide blocks were taken as the output. Finally, the geometric errors of the two guide rails were obtained according to the measured stress. The results show that the maximum difference between the measured geometric errors and the output of BP neural network was 5 μm. Therefore, the correctness and feasibility of the method were verified.
How to Succeed with Film Production in the Regions?
Authors: Sand Stine Agnete 
Published: June 2017

Abstract
This article explores what two regional film production companies in Norway do to survive and succeed with their goals. The production of feature films in Norway is largely an Oslo-based effort, but despite this reality, there are companies in the regions that produce feature films. The analysis draws on semi-structured interviews with eight employees in two companies. Mer Film has in relatively short time managed to attract talented directors and establish networks with international, critically acclaimed production companies. Filmbin was one of the first film companies in Norway who committed themselves to the production of films for children. The article shows that success must be related to context and that reputation, talent development and choice of genre, geographical location, networking and social capital, risk diversification, entrepreneurship, organizational culture and leadership, are essential factors for the companies.
Media Responses to Media Criticism
Authors: von Krogh Torbjörn , Svensson Göran 
Published: June 2017

Abstract
At the time of writing in June 2015, the top Swedish tabloid editors, Thomas Mattsson and Jan Helin, Editors-in-Chief for the competing news organisations, Expressen and Aftonbladet, have produced 116 weekly issues of their joint podcast “MattssonHelin”. An examination of 24 samples of the content regarding responses to media criticism shows that the responses can be categorised in eleven groups that range from total rejection to total acceptance. Our categorisation presents a complement to earlier research on media responses to criticism. The responses contain elements of paradigm repair for journalism (Berkowitz 2000) but also illuminate how the editors use the particular advantages of the podcast format to enhance their take on public media literacy. Their presence in this particular digital platform allows for long and nuanced discussions on journalistic practice in relation to media criticism, albeit on their own terms.
Taxation of Swedish Firm Owners: The Great Reversal from the 1970s to the 2010s
Authors: Henrekson Magnus 
Published: June 2017

Abstract
By the late 1960s, real effective taxation of income from individual firm ownership in Sweden approached 100 percent. A series of tax reforms has reversed this situation. This paper (1) elucidates the thinking behind the vision of creating a largely market-based system without wealthy capitalists and how that vision guided tax policy; (2) outlines and evaluates the changes in the tax code since the late 1970s, their empirical and intellectual basis, and their implications for the taxation of individual firm ownership; and (3) compares the size of the largest individual wealth holdings in the mid-1960s to their equivalents in the 2010s and discusses how the general public’s views have changed regarding sizeable income streams and wealth from business activity. Today, the tax code favors already wealthy individuals, while high labor income taxation combined with a high valuation of existing assets renders wealth accumulation difficult for persons with no initial wealth.
Superhydrophobic and superoleophobic poly(3,4-ethylenedioxypyrrole) polymers synthesized using the Staudinger-Vilarrasa reaction

Published: June 2017

Abstract
Vegetal and animal reigns offer many examples of surfaces with surprising and interesting wetting properties. As example, springtails present superoleophobic properties allowing to live in soil and Lotus leaves show self-cleaning ability even under rainfalls. Indeed, it is known that self-cleaning properties can help to remove dust and particles during rainfalls and as a consequence to clean the surface. The bioinspiration of these surface properties is of a real interest for industrial applications in the nanotechnology field such as photovoltaic systems or anti corrosive material. Here, we use a strategy based on electropolymerization to obtain these properties. The Staudinger-Vilarrasa reaction is used to prepare innovative 3,4-ethylenedioxypyrrole (EDOP) monomers with fluorinated chains. Using C6F13 or C8F17 chains, the polymer surfaces formed after electrodeposition show superhydrophobic and superoleophobic features. Here we study the surface wettability depending on the surface energy (based on the perfluorinated chain length), the surface roughness and morphology.
Determinants of Demand for Physical Activity among Students in Krakow
Authors: Kościółek Szczepan 
Published: June 2017

Abstract
The low level of physical activity amongst Poles is not only a social problem, but also a big challenge for commercial organizations. The aim of the thesis was to determine indicating factors influencing the maximum price that students are prone to pay for physical activity. The research was based on the opinions of 398 respondents (students from Krakow’s academies). A Chi-square test of independence was used to compare the distribution of the observed variables with their theoretical distribution.
The test results show that the maximum price that students are prone to pay for a single admission ticket and for a monthly pass for participating in physical activity is correlated with the price of complementary goods, participation in free and paid kinesthetic forms of recreation, and their main subject of study. In the case of the decision to purchase monthly passes (as opposed to a ticket for single admission), the student’s income and motivation to exercise are also important. On the other hand, declarative price is not influenced by the gender and former sports activity of interviewees.
A Pioneer of Italian Sports Pedagogy and Philosophy
Authors: Isidori Emanuele , Kosiewicz Jerzy 
Published: June 2017

Abstract
The biography we present here in this issue of our journal refers to the story of Italian scholar, educationist, and philosopher, Emanuele Isidori, Vice-Rector for International Relations and Cooperation and head of the Laboratory of General and Sport Pedagogy of the Foro Italico University of Rome in Italy. The biography of Emanuele tells us the story of a pioneer both in sports pedagogy and sports philosophy in his home country of Italy, where the idealist tradition and some prejudices regarding sport and its science seem to have hindered the development process of the two subjects for many years. What emerges from this story is the commitment and strenuous effort of the scholar to develop sports humanities in his country and to help his university and other Italian researchers interested in the scholarly field develop their knowledge through collaboration with the most prestigious European institutions devoted to the study of sport and physical activity.
Ultra Groups as Social Space for Leisure
Authors: Seabra Daniel 
Published: June 2017

Abstract
The paper aims to demonstrate that violence is far from a regular practice in Ultra groups, despite its notorious visibility as transmitted by the media. The paper attempts to demonstrate that Ultra groups are a social space of leisure for young people, rather than a space for violence. Actually, having used observation through direct participation and having registered the discourses of Ultra group members, it is possible to demonstrate that life in these groups represents, for many, not only a break from difficult everyday life, but also the only and/or the most important moment of social leisure in their lives.
The object of this research was four Ultra groups who support the teams of Oporto City: Super Dragõe, Colectivo Ultras 95 (both support Futebol Clube do Porto), Panteras Ngeras (supporting Boavista Futebol Clube), and Alma Salgueirista (supporting Sport Comércio e Salgueiros). The research was based on observation through direct participation made among the groups over six years. Also conducted were 90 semi-structured interviews, 20 autobiographical narratives, and surveys (sample 206 for estimated n=1766).
