Adult Muscle Formation Requires Drosophila Moleskin for Proliferation of Wing Disc-Associated Muscle Precursors

Published: March 2017

Abstract
Adult muscle precursor (AMP) cells located in the notum of the larval wing disc undergo rapid amplification and eventual fusion to generate the Drosophila melanogaster indirect flight muscles (IFMs). Here we find that loss of Moleskin (Msk) function in these wing disc-associated myoblasts reduces the overall AMP pool size, resulting in the absence of IFM formation. This myoblast loss is due to a decrease in the AMP proliferative capacity and is independent of cell death. In contrast, disruption of Msk during pupal myoblast proliferation does not alter the AMP number, suggesting that Msk is specifically required for larval AMP proliferation. It has been previously shown that Wingless (Wg) signaling maintains expression of the Vestigial (Vg) transcription factor in proliferating myoblasts. However, other factors that influence Wg-mediated myoblast proliferation are largely unknown. Here we examine the interactions between Msk and the Wg pathway in regulation of the AMP pool size. We find that a myoblast-specific reduction of Msk results in the absence of Vg expression and a complete loss of the Wg pathway readout β-catenin/Armadillo (Arm). Moreover, msk RNA interference knockdown abolishes expression of the Wg target Ladybird (Lbe) in leg disc myoblasts. Collectively, our results provide strong evidence that Msk acts through the Wg signaling pathway to control myoblast pool size and muscle formation by regulating Arm stability or nuclear transport.
Coordination of Double Strand Break Repair and Meiotic Progression in Yeast by a Mek1-Ndt80 Negative Feedback Loop

Published: March 2017

AbstractMeiotic crossovers and double strand breaks (DSBs) are required for gametogenesis, but entering meiotic divisions with broken chromosomes results in...During meiosis, homologous chromosomes are physically connected by crossovers and sister chromatid cohesion. Interhomolog crossovers are generated by the highly regulated repair of programmed double strand breaks (DSBs). The meiosis-specific kinase Mek1 is critical for this regulation. Mek1 downregulates the mitotic recombinase Rad51, indirectly promoting interhomolog strand invasion by the meiosis-specific recombinase Dmc1. Mek1 also promotes the formation of crossovers that are distributed throughout the genome by interference and is the effector kinase for a meiosis-specific checkpoint that delays entry into Meiosis I until DSBs have been repaired. The target of this checkpoint is a meiosis-specific transcription factor, Ndt80, which is necessary to express the polo-like kinase CDC5 and the cyclin CLB1 thereby allowing completion of recombination and meiotic progression. This work shows that Mek1 and Ndt80 negatively feedback on each other such that when DSB levels are high, Ndt80 is inactive due to high levels of Mek1 activity. As DSBs are repaired, chromosomes synapse and Mek1 activity is reduced below a threshold that allows activation of Ndt80. Ndt80 transcription of CDC5 results in degradation of Red1, a meiosis-specific protein required for Mek1 activation, thereby abolishing Mek1 activity completely. Elimination of Mek1 kinase activity allows Rad51-mediated repair of any remaining DSBs. In this way, cells do not enter Meiosis I until recombination is complete and all DSBs are repaired.
The Nature of Food Commodity Prices Volatility in Driving Inflation and Policy
Authors: Nurliza Nurliza 
Published: March 2017

The objective of research is to analyze the volatility effect of food commodity prices and whether surging food commodity prices have spilled over into food inflation and total inflation with time series data through Box-Jenkins method for 12 food commodity prices. The results have proved that only beef price had high volatility effects and have asymmetric effect. While, soybeans, cooking oil, and food are vulnerable but did not have volatility effects. The change in food commodity prices are significant drive the inflation in the long-term although in the short-term insignificant. The government needs to overcome the full transmission effect of an exogenous shock and to introduce economic reform through investment, infrastructure, and markets for corn and egg for food inflation; eggs and peanuts for total inflation. Besides, strong second-round effects of higher commodity prices on inflation have generally been absent converged to core inflation.DOI: 10.15408/sjie.v6i1.4523

This study examines the relationship between public debt and economic growth in eight countries in Southeast Asia that are members of ASEAN. Through the study will contribute reference for each country to establish their macroeconomic policies. Using 10 years of data from 2006 to 2015 and analysis tools Autoregression Vector (VAR), the study attempts to test the theory of finance led growth. The main finding of this study is that public debt is actually able to increase the economic growth of a country significantly, although it takes a few years of its existence. This finding supports several previous studies that demonstrate the important role of government debt to the economy of a country.DOI: 10.15408/sjie.v6i1.4779
THE CONTRIBUTION OF THE BLŪMĪTIS FAMILY TO LATVIA
Authors: Gaitniece Lāsma , Zigmunde Alīda 
Published: March 2017

The aim of this article is to show through research in the archives and libraries of Latvia what the Blūmītis family accomplished in the first half of the 20th century for Latvia and how they worked successfully for the children's asylum and the private school. As even today people are speaking about the Blūmītis family, it is necessary to ask the question why this is so and what was so outstanding about this family. Out of the three brothers Osvalds Blūmītis (1903–1971) is the best known. After his studies in England at the Spurgeon's college he returned to his home-village Tilža in Latgale and founded a children's asylum there in 1928. Not only orphans found their new home there, but also many children from poor families who were impoverished by alcoholism. The children belonged to different religious communities; there were not only Baptists like Osvalds Blūmītis, but also Roman-Catholics, Lutheran-Protestants and Russian-Orthodox. Since 1927 a Baptist private school existed in Tilža which later was renamed Osvalds Blūmītis School. Besides this school there existed a children's asylum and a private primary school, which were financed by donations from Latvia, England, Sweden and Brazil. Untill 1940 there was only one institution of this kind for orphans in Latgale. About 200 children found loving care and shelter in it.Osvald’s brothers, Arturs and Adolfs were also Baptist priests as he was. Arturs Blūmītis founded a children's asylum in Jaunjelgava in 1939. In 1940 the Baptist orphan asylums and primary schools were closed. Osvalds Blūmītis left Latvia in 1939 and continued his activities in the US. When he arrived in the US, he started to work as a real estate agent but later continued his work for the Baptist church. Osvalds Blūmītis has helped about 250 Latvians to start a new life after arrival in the US. He fought communism and the policies of the Soviet Union. He also conducted radio shows ''The voice of the oppressed people''. Osvalds, Arturs and Adolfs left the country at the end of the war and became entrepreneurs in America. The active participation of the Blūmītis family – their sister and mother worked in the orphanage too – shows us how much this family was able to do for the needy.

Published: March 2017

RESUMO O artigo parte de uma breve descrição das recentes manifestações populares ocorridas no Brasil em protesto contra diversos aspectos da economia e da política brasileira. Partindo da diversidade de bandeiras de luta destes movimentos, analisa a concepção de ciência por trás das críticas feitas a eles. Descreve a apropriação das tecnologias de informação e comunicação pela juventude na cobertura destes eventos e a crise instalada na tradicional mídia de massa. O texto analisa os conceitos de educação que estão postos em debate, fazendo uma crítica à visão produtivista que toma conta da educação em todo o mundo. A partir destas considerações, propõe a implantação de um “ecossistema pedagógico de aprendizagem e de produção de culturas e conhecimento” como sendo uma das possibilidades para a escola enfrentar os desafios contemporâneos.Palavras-chave: Redes Sociais; Educação; Ativismo; Políticas Educacionais. ABSTRACT The paper begins with a brief description of recent demonstrations in Brazil against various economic and politics aspects. From the diversity of their demands the paper analyses the concept science used to criticize these demonstrations. The use of Information and Communication Technologies by youth in coverage of these events and the consequent by passing of the traditional mass media are examined. Education was one of the most common complaints and we ask what kind of education they want. Continuing the present system base on productivity approach will not solve the problem. We propose an “ecosystem of teaching and learning to promote the production of culture and knowledge” as a way for schools to face contemporary challenges.Keywords: Social Networks; Education; Activism; Educational Politics.

RESUMO Busca-se avaliar o enquadramento jornalístico feito pelos jornais da mídia corporativa que legitimam e medeiam a pauta pública e a estratégia da política de segurança pública do Rio de Janeiro, recorrendo à cobertura de notícias sobre os protestos realizados nas ruas da cidade durante o “Junho Furioso”. A partir do uso de semânticas estereotipadas para noticiar o fato jornalístico pela imprensa, será avaliada a criação de um imaginário social coletivo como espaço público de disputa de hegemonia conforme a concepção gramsciana, criminalizando midiaticamente as áreas pobres da cidade do Rio de Janeiro para obtenção de um controle da ordem pública.Palavras-chave: Mídia corporativa; Hegemonia gramisciana; Política de Segurança Pública; “Junho Furioso”; Controle e ordem social. ABSTRACT This article evaluates the journalistic framing by corportative media, which legitimize and mediate the public agenda and Rio de Janeiro's public security policy strategy, using the news coverage of the protests in the city streets ​​during the "Furious June". Drawing on the stereotypical use of semantics for journalistic fact reporting by the press, the creation of a collective social imagination will be evaluated as a public space of dispute for hegemony as in Gramsci's conception, mediatically criminalizing the poor areas of the city of Rio de Janeiro with the aim of controling public order.Keywords: Corportativa media; Gramsci's Hegemony; Public Security Policy; " Furious June "; Control and social order.

RESUMO Discute o papel dos usuários e suas práticas de colaboratividade em nível web 2.0 dentro do paradigma tecnológico e da cultura de convergência midiática. Trata-se de uma investigação epistemológica, respaldada numa revisão da literatura. Como resultados, percebe-se que o ato de compartilhar ainda se depara com a ideia de que a informação é sinônimo de poder. E, nessa perspectiva, o protagonismo do usuário diante das plataformas digitais deve ser verificado com cautela, tendo em vista a supremacia de grandes empresas da web que atuam de modo a restringir as pretensas liberdades infocomunicacionais, ao mesmo tempo que garantem zonas de influência específicas, nas quais a confiança na sistematização das respostas é quase que comparável ao “fio de Ariadne”.Palavras-chave: Convergência Midiática; Web 2.0; A Fábula da Autonomia; Usuários; Colaboratividade.ABSTRACT This article discusses the role of users and their collaborative practices on Web 2.0 within the technological paradigm and the culture of media convergence. This is an epistemological investigation based on a review of the literature. As a result, one realizes that the act of sharing still confronts the idea that information is synonymous with power. And from this perspective, the role of the user regarding Digital Platforms should be examined carefully, considering the supremacy of large Web companies that act to restrict the alleged infocommunicative freedoms while assuring specific areas of influence where confidence in the systematization of the answers is almost comparable to Ariadne's thread.Keywords: Media Convergence; Web 2.0; The Fable of Autonomy; Users; Collaborativity.
