Authors: Baliscei João Paulo , Teruya Teresa Kazuko , Stein Vinícius
Published: May 2016

Neste artigo de cunho bibliográfico temos por objetivo problematizar as representações de masculinidades criadas e divulgadas pelos anúncios publicitários. Para a realização de tal objetivo, realizamos análises sobre duas propagandas de automóveis endereçadas aos consumidores homens. Para tanto, respaldamo-nos em autores e autoras dos Estudos Culturais (CUNHA, 2008; GREGOLIN, 2007; HALL, 2001; 2006; HERNÁNDEZ, 2007; NUNES, 2010; KELLNER, 2001; 2012 SABAT, 2001; SILVA, 2001) que nos auxiliam na compreensão e problematização das pedagogias culturais intrínsecas às imagens do cotidiano. Por último, argumentamos sobre a necessidade de professores e professoras desenvolverem estratégias pedagógicas para que incentivem o estudo visual crítico na educação escolar.

Esta pesquisa abre uma discussão sobre a trilha sonora dos filmes Tropa de Elite 1 e 2, dirigido pelo cineasta brasileiro José Padilha nos anos de 2007 e 2010, respectivamente. Desse modo, ressaltamos que a trilha sonora composta para os filmes, é um objeto de estudo importante, uma vez que o seu conteúdo crítico e político consegue atingir uma enorme quantidade de pessoas por meio da indústria cultural. Por meio de metodologia histórica e bibliográfica, concluímos que a trilha sonora dos dois filmes, constroem uma expressão crítica através da arte da música e do cinema, sobre os graves problemas sociais, políticos e econômicos localizados na cidade do Rio de Janeiro.
No espelho de muitas faces: miradas caleidoscópicas sobre arte e vida, currículo e formação
Authors: Mertins Mirian Celeste
Published: May 2016

O presente artigo foi construído como miradas em um espelho de muitas faces onde se misturam e se condensam arte, vida e ciência.  De que arte falamos quando olhamos a vida dentro e fora da escola? Dispensável, supérflua? As miradas nos revelam aspectos como num caleidoscópio que mira as livrarias, as escolas, os museus, as obras de arte, a formação inicial nos cursos de Pedagogia, a construção de uma poiesis, entre experiências vividas e teóricos parceiros. Frente a este espelho de muitas faces, é possível vislumbrar a importância das artes na contemporaneidade e, em especial, a atuação concreta, singular e necessária de quem nela acredita.

O Vídeo como potencializador da Arte Educação Digital Crítica
Authors: Da Silva Moreira Paulino Antonio
Published: May 2016

O presente artigo discute a utilização do vídeo como potencializador da e-arte/educação, essa pesquisa nasceu como conclusão do curso de Especialização em Arte/Educação Intermidiática Digital, intitulado “O vídeo como potencializador da arte/educação digital crítica”. A pesquisa aqui apresentada discute a necessidade de desenvolver a consciência crítica dos estudantes por meio do vídeo, abordando uma temática de violência, problematiza-se os atos corriqueiros e que devido a tanta incidência dos mesmos, tornam-se comuns, e é isso que a ação pedagógica procura mudar, ela pega um ato do dia-a-dia não pensado e faz pensar. Utilizar-se-á pesquisas bibliográficas e leituras diversas para potencializar a arte/educação, com o objetivo da ação pedagógica para promover a leitura crítica de um mundo descortinado e o desenvolvimento da consciência plena e crítica do mundo, em que a ação pedagógica crítica e criativa visualiza as diversas possibilidades viáveis para atingir os objetivos educacionais desejados na educação, definindo as ações pedagógicas. Isso quer dizer que educadores devem perceber a relação entre a arte-educação digital crítica e o conteúdo, tanto no sentido da aquisição e construção do conhecimento quanto do desenvolvimento de valores, trazendo ao sujeito a possibilidade de fazer escolha autônoma, que a professora Fernanda Pereira da Cunha aponta como educação libertária, facilitadora de interações e da aprendizagem, na área da arte/educação.
Educação e arte: a consolidação de um campo interminável
Authors: Pereira Marcos Villela
Published: May 2016

O objetivo deste artigo é explorar algumas considerações acerca da educação, da arte e da relação entre elas, de modo a mostrar a condição interminável desse campo de estudo e investigação. Tomando como horizonte a formação de professores, reitero uma remessa ao entrecruzamento dos processos de subjetivação e o entendimento estético: a estética da existência como tema clássico na história da humanidade e a formação como um complexo e multifacetado processo de produção de subjetividade – formar os outros e formar a si mesmo como uma intrincada arte de existir. O lugar da arte na educação, a relação entre arte e educação, o lugar da arte na vida, o sentido da educação, as implicações entre a vida, a arte e a educação, quem vem antes, quem vem depois, quem depende de quem, quem se serve de quem: não tanto o conteúdo dessa problematização, não tanto as respostas, mas é o próprio movimento de perguntar que interessa ser problematizado. Como corpus de problematização, serão tomados quatro textos da importante arte-educadora brasileira Noêmia Varela, professora da Escolinha de Arte do Recife: “Criatividade na escola e formação do professor”, de 1972; “Movimento Escolinhas de Arte: imagens e idéias”, de 1973; “O desafio da formação de recursos humanos para a educação através da arte”, de 1977; e “A formação do arte educador no Brasil”, de 1984. O material será confrontado com categorias contemporâneas do campo da educação e da arte, buscando-se especular seu potencial infinito de investigação.Palavras-chave:  educação e arte; educação estética; ensino de arte

O comportamento humano no pensamento institucionalista: uma breve discussão
Authors: Barcelos Olinda
Published: May 2016

Este artigo tem como objetivo analisar o comportamento humano sob o enfoque de três abordagens do pensamento institucionalista. O comportamento humano, para os “tradicionais”, não tende ao equilíbrio, a um fim, não é inerte, ele é mutável e sujeito a um conjunto de normas, valores e regras. O comportamento do indivíduo é influenciado pelasinstituições, mas também influencia e as transforma através da ação coletiva. Para a Nova Economia Institucional (NEI), o comportamento humano é oportunista (nas formas de manifesto,sutil e natural) e possui racionalidade limitada, conforme apregoado por Simon. A abordagem neo-institucionalista resgata importantes conceitos dos “velhos”, destacando que o comportamento humano não tende ao equilíbrio, pode até objetivar a otimização deresultados, mas nada garante que terá sucesso, pois o ambiente é incerto e recheado de dúvidas. O núcleo da análise versa que o comportamento humano é imprevisível, molda e é moldado pelos instintos, pelos hábitos, pelo oportunismo, pela racionalidade limitada, sujeito a um conjunto de normas e regras que podem alterar suas relações econômicas. Ocomportamento humano não é “dado”, não tende ao equilíbrio econômico e ao ponto ótimo.

La exclusión social en la teoría social de Niklas Luhmann
Authors: García Blanco José María
Published: May 2016

El objetivo de este artículo es analizar el concepto de exclusión social en la teoría social de Niklas Luhmann. Se parte de una breve presentación del origen de dicho concepto en el ámbito de la investigación y la política social europeas, para poder ver el paralelismo temporal entre este desarrollo general del concepto y el que tiene lugar en la obra del sociólogo alemán. Luego, tras exponer y analizar lo que entendía Luhmann por exclusión, se pasa revista a su teoría acerca de los principales dispositivos de promoción de la inclusión y de lucha contra la exclusión de nuestra sociedad: el Estado de bienestar y su sistema de servicios sociales. Finalmente, se concluye con una propuesta sintética de las que considero aportaciones más relevantes realizadas por Luhmann a la problemática de la exclusión, tanto para la investigación social como para el diseño de las políticas sociales y de desarrollo. http://dx.doi.org/10.5902/6384
O acoplamento entre sociedade e economia: a teoria dos sistemas nas contribuições de Talcott Parsons e Niklas Luhmann
Authors: Neves Fabrício Monteiro , Aguilar Filho Hélio Afonso De
Published: May 2016

Mais recentemente, a preocupação comum de sociólogos e economistas com temas que pareciam ser antes exclusivos à sociologia e à economia tem suscitado importantes reflexões sobre as possibilidades da cooperação interdisciplinar. Contribuições dos dois lados têm sido relevantes nesse sentido. Na economia, assiste-se ao resgate do institucionalismo, que, mesmo sobre novas roupagens, tem dado um caráter mais social às pesquisas econômicas. Na sociologia, o surgimento de uma disciplina específica, a Nova Sociologia Econômica, também caminha reforçando a preocupação com o caráter social dos fenômenos econômicos. O presente trabalho, à luz dessas preocupações, discute o imbricamento social da esfera econômica. A ênfase, contudo, é na Teoria dos Sistemas de Talcott Parsons e Niklas Luhmann, pelo entendimento de que esta, principalmente na perspectiva do segundo autor, pode apresentar contribuições tanto do ponto de vista formal quanto substantivo para aproximar o domínio econômico do social. http://dx.doi.org/10.5902/6387
One-Cell Analysis as a Technique for True Single-Cell Analysis of Organelles in Breast Tumor and Adjacent Normal Tissue to Profile Fatty Acid Composition of Triglyceride Species
Authors: Jason S. Hamilton  , Guido F. Verbeck
Published: May 2016

Breast cancer develops in an adipose rich environment of normal adipocytes that are known to aid in tumor progression through an unknown method of lipid transfer from normal cells to tumor cells. Much research is built around lipid analysis of breast tumor and adjacent normal tissues to identify variations in the lipidome to gain an understanding of the role lipids play in progressing cancer. Ideally, single-cell analysis methods coupled to mass spectrometry that retain spatial information are best suited for this endeavor. However, many single-cell analysis methods are not capable of subcellular analysis of intact lipids while maintaining spatial information. One-Cell analysis is a true single-cell technique with the precision to extract single organelles from intact tissues while not interfering or disrupting adjacent cells. This method is used to extract and analyze single organelles from individual cells using nanomanipulation coupled to nanoelectrospray ionization mass spectrometry. Presented here is a demonstration of the analysis of single lipid bodies from two different sets of breast tumor and normal adjacent tissues to elucidate the fatty acid composition of triglycerides using One-Cell analysis coupled to tandem mass spectrometry. As a result, thirteen fatty acid species unique to the tumor tissues were identified, five in one set of tissues and eight in the other set.

Authors: Jamal Zekri  , Syed Mustafa Karim  , Ahmed Al-Shehri  , Mervat Mahrous  , Tarek Darwish  , Hani El Taani
Published: May 2016

Background: Colorectal cancer (CRC) is a significant healthcare burden worldwide and in the Middle East (ME). KRAS mutation confers resistance to epidermal growth factor receptor (EGFR) inhibitors in the treatment of advanced CRC. Data regarding the rate of KRAS mutation from the ME are scattered and scarce. We aim to collect and review all sizable studies evaluating the frequency of KRAS mutations in CRC patients from the ME. Method: A Pubmed and Google Scholar search was conducted using keywords including KRAS, K-ras, colorectal cancer and Middle East, along with names of each ME country. Studies including over 90 patients were included in the review. Result: Eleven studies containing more than 90 patients were identified. Among all eleven studies, KRAS mutation rate ranged from 13 to 56%. Five studies reported KRAS mutation rate in M1 stage either exclusively or as part of subgroup analysis. In these studies, mutations were found in 8-45% of cases. KRAS mutations were associated with female gender, M1 stage and high CEA in 3, 2, and 1 studies respectively. Conclusion: There is a broad range of variability in KRAS mutation rate reported in different studies from the ME. This may have been due to small number of patients in the studies and lack of centralized testing for KRAS mutations. Larger and more coordinated studies from the ME population are required to ascertain the accuracy of KRAS mutation rate.
An inhibitory corticostriatal pathway
Authors: Rock Crystal , Zurita Hector , Wilson Charles , Apicella Alfonso junior
Published: May 2016

Anatomical and physiological studies have led to the assumption that the dorsal striatum receives exclusively excitatory afferents from the cortex. Here we test the hypothesis that the dorsal striatum receives also GABAergic projections from the cortex. We addressed this fundamental question by taking advantage of optogenetics and directly examining the functional effects of cortical GABAergic inputs to spiny projection neurons (SPNs) of the mouse auditory and motor cortex. We found that the cortex, via corticostriatal somatostatin neurons (CS-SOM), has a direct inhibitory influence on the output of the striatum SPNs. Our results describe a corticostriatal long-range inhibitory circuit (CS-SOM inhibitory projections → striatal SPNs) underlying the control of spike timing/generation in SPNs and attributes a specific function to a genetically defined type of cortical interneuron in corticostriatal communication.
The role of precipitation and spatial organization in the response of trade‐wind clouds to warming
Authors: Vogel Raphaela , Nuijens Louise , Stevens Bjorn
Published: May 2016

Using highly resolved large‐eddy simulations on two different domain sizes, we investigate the influence of precipitation and spatial organization on the thermodynamic structure of the trade‐wind layer, under a uniform 4 K warming at constant relative humidity. In nonprecipitating simulations, the increased surface latent heat flux in the warmer climate produces a deeper and drier cloud layer with reduced cloud fractions between 1.5 and 4 km. Precipitation prevents the deepening and drying of the cloud layer in response to warming. Cloud fractions still decrease in the upper cloud layer, because stratiform outflow layers near cloud tops are less pronounced and because the larger liquid water contents are confined to narrower updrafts. Simulations on a 16‐fold larger domain lead to the spatial organization of clouds into larger and deeper cloud clusters. The presence of deeper clouds results in a shallower, warmer, and drier trade‐wind layer, with strongly reduced cloud cover. The warming response in the precipitating large‐domain simulation nevertheless remains similar to the small‐domain precipitating simulation. On the large domain, deeper clouds can also develop without precipitation, because moisture‐convection feedbacks strengthen in the absence of cold‐pool dynamics. Overall, total cloud cover and albedo decrease only slightly with warming in all cases. This demonstrates the robustness of shallow cumuli—in particular of cloud fraction near the lifting condensation level—to changes in the large‐scale environment.
Mutations Y493G and K546D in human HSP90 disrupt binding of celastrol and reduce interaction with Cdc37
Authors: Peng Bin , Gu Yi‐Jun , Wang Ying , Cao Fan‐Fan , Zhang Xue , Zhang Deng‐Hai , Hou Jian
Published: May 2016

Celastrol, a natural compound derived from the Chinese herb Tripterygium wilfordii Hook F, has been proven to inhibit heat shock protein 90 (HSP90) activity and has attracted much attention because of its promising effects in cancer treatment and in ameliorating degenerative neuron diseases. However, the HSP90 structure involved in celastrol interaction is not known. Here, we report a novel celastrol‐binding pocket in the HSP90 dimer, predicted by molecular docking. Mutation of the two key binding pocket amino acids (Lys546 and Tyr493) disrupted the binding of celastrol to HSP90 dimers, as detected by isothermal titration calorimetry (ITC). Interestingly, such mutations also reduced binding between HSP90 and the cochaperone Cdc37, thus providing a new explanation for reported findings that celastrol shows more obvious effects in disrupting binding between HSP90 and Cdc37 than between HSP90 and other cochaperones. In short, our work discloses a novel binding pocket in HSP90 dimer for celastrol and provides an explanation as to why celastrol has a strong effect on HSP90 and Cdc37 binding.
A study of the molecular variants associated with lactase persistence in different Ecuadorian ethnic groups
Authors: Paz‐Y‐Miño César , Burgos Germán , López‐Cortés Andrés , Herrera Camilo , Gaviria Anibal , Tejera Eduardo , Cabrera‐Andrade Alejandro
Published: May 2016

Objective

Lactase persistence (LP) is an adaptive trait that certain human populations have acquired in response to lactose consumption in adulthood. The T‐13910 variant has been reported as a causal polymorphism in Europeans. The Ecuadorian population has been described as multicultural and multiethnic, comprised of three main ethnic groups (Mestizo, Native Amerindian, and Afro‐Ecuadorian). The aim of the study was to identify the molecular basis of LP in these admixed populations for the first time and determine the association between the T‐13910 marker and the European ancestry proportion of each ethnic group.

Methods

Genotyping was performed in 741 Ecuadorian individuals by sequencing a 576 bp region around the ‐13910 position upstream of the LCT gene. The ancestry proportions of Mestizo, Afro‐Ecuadorian, and Native Amerindians were calculated using Ancestry Informative Markers and were compared with the diversity panel of the Human Genome Diversity Project.

Results

LP prevalence calculated from T‐13910 allele frequency in Mestizo, Afro‐Ecuadorian, and Native Amerindians was 24.4%, 16%, and 12.5%, respectively. The ancestry percentage correlated to the admixture proportion of each ethnic group, and the C/T‐13910 genotype frequency was influenced by the European ancestry proportion.

Conclusions

The presence of the T‐13910 polymorphism in the Ecuadorian population suggested that LP was a trait introduced by European migration and inherited by admixture that occurred during the colonization of South America. This variant was not fixed in a population with a history of admixture, and its allele frequency was proportional to the ancestry proportion of each Ecuadorian ethnic group. Am. J. Hum.

Emerging targeted drug therapies in skeletal dysplasias
Authors: Yap Patrick , Savarirayan Ravi
Published: May 2016

Quantum advances have occurred in the field of human genetics in the six decades since Watson and Crick expressed their “wish to suggest a structure for the salt of deoxyribose nucleic acid.” These culminated with the human genome project, which has opened up myriad possibilities, including that of individualized genetic medicine, the ability to deliver medical advice, management, and therapy tailored to an individual's genetic blueprint. Advances in genetic diagnostic capabilities have been rapid, to the point where the genome can be sequenced for several thousand dollars. Crucially, it has facilitated the identification of targets for “precision” treatments to combat genetic diseases at their source. This manuscript will review the innovative, pathogenesis‐based therapies that are revolutionizing management of skeletal dysplasias, giving patients and families new options and outcomes. © 2016 Wiley Periodicals, Inc.

Published: May 2016

We demonstrated the fabrication of freestanding zeolitic imidazolate framework 7 (ZIF‐7) nanofiber (NF) mats by means of one‐step, scalable electrospinning. The formation of ZIF‐7 nanoparticles embedded in polymer fibers was unambiguously pinpointed via X‐ray diffraction, transmission electron microscopy, and adsorption studies. The NF mats exhibited excellent characteristics, with an average diameter of 245 nm, in the adsorption and desorption of carbon dioxide (CO2); this makes them attractive candidates for gas separation and other selective filtration applications. This excellent property of the ZIF‐7 mats was explained by the gate‐opening phenomenon of ZIF‐7, which yielded a stepwise increase in the overall CO2 uptake capacity. The mechanical strength of the NF mats was also obtained via large‐strain uniaxial tensile deformation, which enabled preliminary assessment of the mat's suitability for textiles and membranes in targeting separation and filtration applications with large‐area permeability. © 2016 Wiley Periodicals, Inc.

Effects of polyethyleneimine molecular weight and proportion on the membrane hydrophilization by codepositing with dopamine
Authors: Yang Hao‐Cheng , Wu Ming‐Bang , Li Yong‐Jiu , Chen Yi‐Fu , Wan Ling‐Shu , Xu Zhi‐Kang
Published: May 2016

Mussel‐inspired chemistry has attracted widespread interest in the surface modification of polymer membranes. We have previously demonstrated a dopamine (DA) assisted codeposition process of polyethyleneimine onto polypropylene microfiltration membranes (PPMMs) for surface hydrophilization. In this work, we further investigate the effects of PEI molecular weight and DA/PEI mass ratio on the codeposition process and membrane performance. The results indicate that only low‐molecular‐weight PEI bring a distinct promotion in both surface wettability and water permeation flux for PPMMs. On the other hand, either excess DA or PEI is detrimental to the surface hydrophilicity of the studied membranes. The optimized PEI molecular weight is 600 Da and the corresponding mass ratio is 1:1 for the surface hydrophilization of PPMMs. These results are beneficial to understand those codeposition processes of dopamine with other polymers. © 2016 Wiley Periodicals, Inc.

The role of conductive pathways in the conductivity and rheological behavior of poly(methyl methacrylate)–graphite composites
Authors: Liu Xianhu , Pan Yamin , Hao Xiaoqiong , Dai Kun , Schubert Dirk W.
Published: May 2016

Up to now, research on the dynamic process of conductive network formation has tended to focus on composite particles with one‐dimensional geometry, such as carbon black and carbon nanotubes. However, studies on this subject based on fillers with two‐dimensional structure, such as graphite, are rare in the literature. In this work, the dynamic percolation and rheological properties of poly(methyl methacrylate) (PMMA)–graphite composites under an electric field were investigated. The activation energies of conductive network formation and polymer matrix mobility were calculated from the temperature dependence of the percolation time and the zero‐shear viscosity. It was found that the activation energy calculated from the zero‐shear viscosity was not influenced by the electric field in the concentration range investigated, but the electric field had an effect on the activation energy calculated from the percolation time. This finding emphasizes that the electrical and rheological properties have different physical origins. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43810.
A novel role for integrin‐linked kinase in periodic mechanical stress‐mediated ERK1/2 mitogenic signaling in rat chondrocytes
Authors: Song Huanghe , Liang Wenwei , Xu Shun , Li Zeng , Chen Zhefeng , Cui Weiding , Zhou Jinchun , Wang Qing , Liu Feng , Fan Weimin
Published: May 2016

In recent years, a variety of studies have been performed to investigate the cellular responses of periodic mechanical stress on chondrocytes. Integrin β1‐mediated ERK1/2 activation was proven to be indispensable in periodic mechanical stress‐induced chondrocyte proliferation and matrix synthesis. However, other signal proteins responsible for the mitogenesis of chondrocytes under periodic mechanical stress remain incompletely understood. In the current investigation, we probed the roles of integrin‐linked kinase (ILK) signaling in periodic mechanical stress‐induced chondrocyte proliferation and matrix synthesis. We found that upon periodic mechanical stress induction, ILK activity increased significantly. Depletion of ILK with targeted shRNA strongly inhibited periodic mechanical stress‐induced chondrocyte proliferation and matrix synthesis. In addition, pretreatment with a blocking antibody against integrin β1 resulted in a remarkable decrease in ILK activity in cells exposed to periodic mechanical stress. Furthermore, inhibition of ILK with its target shRNA significantly suppressed ERK1/2 activation in relation to periodic mechanical stress. Based on the above results, we identified ILK as a crucial regulator involved in the integrin β1‐ERK1/2 signal cascade responsible for periodic mechanical stress‐induced chondrocyte proliferation and matrix synthesis.
