DEPENDÊNCIA SETORIAL DE INSUMOS IMPORTADOS DO SETOR AGROPECUÁRIO E DA INDÚSTRIA INTENSIVA EM RECURSOS NATURAIS: UMA ANALISE DO PERÍODO DE 1995 A 2009
Authors: Mortari Valéria Silva , Oliveira Maria Aparecida Silva
Published: July 2017

Este trabalho tem por objetivo analisar o grau de dependência por insumos importados do setor agropecuário e da indústria intensiva em recursos naturais entre os anos de 1995 e 2009. Outro ponto é analisar os transbordamentos gerados por tais setores na economia. Desta forma, utilizou-se a análise de insumo-produto, calculando os requerimentos diretos e indiretos por importação de insumos de cada setor e os classificando de acordo com seus respectivos graus de dependência externa. Quanto ao efeito de encadeamento empregaram-se os índices de ligação para frente de Ghosh e o para trás de Rasmussen Hirschman (RH). Foi constatado que a economia apresenta dependência externa de insumos relacionada ao setor agropecuário e que este setor possui importantes encadeamentos a jusante em sua cadeia produtiva. Quanto à indústria intensiva em recursos naturais os resultados podem ser divididos em dois: (1) dois dos quatro setores da indústria extrativa mineral apresentam dependência externa para produzir e dentre os quatro a economia se mostra dependente da importação de três deles como insumos; e (2) a indústria de alimentos mostrou, no geral, baixa dependência externa, e foi no geral classificada como dependente da oferta inter-setorial de acordo com seus índices de ligação.

Published: July 2017

In this study, an efficient method for regenerating plants from nodal cultures of seedlings was developed for Aspidosperma polyneuron. Mature seeds were surface-sterilized and embryos were germinated in Woody Plant Medium (WPM). Epicotyl and hypocotyl nodal segments, excised from 3-week-old in vitro-grown seedlings, were cultured in WPM medium supplemented with 6-benzyladenine (BA) (2.5, 5.0, and 10 mM), alone or combined with indole-3-butyric acid (IBA) or a-naphthaleneacetic acid (NAA) (0.5 mM) for culture initiation and three subcultures. For root induction, IBA (2.5, 5.0, and 10 mM) pulse treatments (15 minutes) were initially applied, followed by transfer to growth regulator-free WPM for five weeks. Regenerated plants were first transplanted to trays containing soil and Plantmax® substrate (3:1) and later to polyethylene bags for acclimatization in a greenhouse. Hypocotyl explants exhibited superior shoot regeneration rate and rooting percentages compared with those of epicotyl explants. The highest numbers of shoots per explant (7-8) were obtained at the third subculture when using the culture medium supplemented with 10 mM BA. When combined with BA, the addition of 0.5 mM IBA or NAA did not affect the regeneration of shoots. An IBA pulse treatment of 5-10 mM for 15 minutes induced 60% of rooting. The regenerated plants were acclimatized and successfully established in a greenhouse, with a 90% survival rate observed after three months. Based on the results of this study, the micropropagation of Aspidosperma polyneuron from in vitro seedlings is feasible and could be a useful tool for the conservation and propagation of this important endangered species.

O presente trabalho objetivou avaliar a contaminação biológica ao longo do tempo em uma comunidade arbórea em estágio sucessional avançado/tardio da Floresta Ombrófila Mista Montana, adjacente a um plantio de Pinus taeda L. em Lages - SC. Para isso, foram alocadas 25 parcelas de 20 x 20 m, distribuídas em cinco transeções de cinco parcelas cada, alocadas perpendiculares à borda de contato com o plantio de pinus. Em cada parcela foram mensurados (DAP ≥ 5 cm, medido a 1,30 m do solo), coletados e identificados todos os indivíduos arbóreos vivos. Quatro anos após o primeiro inventário, os mesmos indivíduos foram novamente inventariados, quantificando-se os indivíduos mortos, sobreviventes e adicionando os recrutas. Para os dois períodos foram calculados os descritores fitossociológicos, quantificados os indicadores de invasão para a comunidade como um todo e grupos ecológicos e calculadas as taxas demográficas. No primeiro ano foram amostradas 73 espécies e no segundo 74 espécies, dentro das quais, duas foram exóticas: Pinus taeda e Ligustrum lucidum W.T. Aiton. Ambas tiveram baixos valores dos indicadores de invasão para a comunidade nos dois anos, no entanto, com aumento da participação de Pinus taeda entre as espécies pioneiras ao longo do tempo. Os resultados das taxas demográficas sugerem que, para os diferentes grupos ecológicos, o processo de invasão encontra-se em fases distintas. Conclui-se que o grupo das espécies pioneiras foi o componente mais afetado pela invasão biológica, o que reforça a necessidade de análise, considerando os diferentes grupos ecológicos.

O processo de revegetação representa uma alternativa para recuperação de áreas com solo exposto. Este trabalho objetivou avaliar o crescimento de mudas de Dipteryx alata (baru) e Astronium fraxinifolium (gonçalo-alves) em solo degradado, compactado ou não, suplementado com resíduo agroindustrial e verificar a possibilidade de uso deste como condicionante do solo. O experimento, conduzido na UNESP/Campus de Ilha Solteira, em cultivo protegido, apresenta três doses de resíduo (0, 15 e 30 t ha-1), duas densidades (1,0 e 1,5 g cm-3) e duas plantas indicadoras (Dipteryx alata e Astronium fraxinifolium). As plantas, arbóreas de cerrado, ocorrem nas proximidades da área degradada, onde o solo foi coletado. As mudas foram avaliadas 7 meses após desbaste, para altura, diâmetro do caule, número de folhas, massa fresca e seca da parte aérea e do sistema radicular, e o solo foi avaliado para análise da fertilidade. Os resultados mostram que o resíduo agroindustrial (RA) elevou pH, teores de potássio, cálcio e magnésio, e diminuiu o alumínio disponível. O Dipteryx alata teve a massa fresca da raiz influenciada negativamente pela compactação e se mostrou pouco exigente quanto à adição de nutrientes pelo RA. O Astronium fraxinifolium teve a massa fresca da raiz e a altura negativamente influenciados pela compactação, enquanto a adição do RA favoreceu altura, diâmetro do caule, massa fresca e seca da parte aérea e do sistema radicular. A morfologia das raízes foi alterada pela compactação, nas duas espécies. O substrato utilizado apresenta elevada capacidade de reorganização, produzindo elevada densidade sem aplicação de força.

No estado do Rio Grande do Sul, os reflorestamentos de eucalipto encontram-se, geralmente, em solos de baixa fertilidade natural, favorecendo a associação ectomicorrízica. Neste trabalho, avaliou-se o efeito da inoculação dos isolados de fungos ectomicorrízicos UFSC-Pt116, UFSC-Pt188 e UFSC-SA9, sobre plantas de Eucalyptus grandis, em Neossolo Quartzarênico. As avaliações foram realizadas aos 30, 45, 60, 75 e 90 dias após semeadura. Plantas inoculadas com os isolados UFSC-Pt116, UFSC-Pt188 e UFSC-SA9 alcançaram maior altura, diâmetro do caule, massa seca da parte aérea e volume de raízes em relação ao controle. Plantas inoculadas com o isolado de fungo ectomicorrízico UFSC-Pt188 apresentaram maior teor de fósforo e potássio na parte aérea que as plantas não inoculadas. A inoculação com o isolado fúngico ectomicorrízico UFSC-Pt116 promoveu maior altura e massa seca da parte aérea. Para os teores de nitrogênio e potássio, e para massa seca de raízes não foram observadas diferenças significativas entre os tratamentos. A inoculação com os fungos ectomicorrízicos UFSC-Pt116, UFSC-SA9 e UFSC-Pt188 isoladamente, promoveram maior altura, diâmetro de caule, acúmulo de massa seca da parte aérea e volume de raízes das plantas de Eucalyptus grandis.

A recuperação de diferentes ecossistemas degradados demanda pesquisas com espécies florestais nativas que possam subsidiar programas de recuperação florestal. A produção de mudas com espécies arbóreas nativas em associação com os microrganismos do solo é uma importante técnica para a reabilitação desses ambientes. O presente trabalho teve como objetivo avaliar os efeitos da inoculação com fungos micorrízicos arbusculares (FMAs) e nutrição fosfatada sobre o crescimento e conteúdos nutricionais de mudas de paricá [Schizolobium parahyba var. amazonicum (Huber ex Ducke) Barneby)]. O experimento foi conduzido em casa de vegetação por um período de 75 dias, utilizando-se o delineamento experimental inteiramente casualizado, em esquema fatorial 4 x 4, inoculação com os FMAs: Rhizophagus clarus, Gigaspora margarita, inóculo misto (Rhizophagus clarus + Gigaspora margarita) e controle (sem FMAs); quatro doses de P: 0, 60, 120 e 180 mg dm-3 de solo, com quatro repetições. Foram avaliadas as variáveis altura, matéria seca da parte área (MSPA), matéria seca da raiz (MSR), área foliar (AF), diâmetro do coleto (DC) e os conteúdos de N, P, K, Ca e Mg na parte aérea. As mudas de paricá apresentaram maior porcentagem de colonização para Rhizophagus clarus e o inóculo misto (80 e 90%, respectivamente), diferentemente do observado para a espécie Gigaspora margarita, com menor porcentagem (20%). O Rhizophagus clarus e o inóculo misto, na ausência de P, propiciaram incremento para as variáveis de crescimento em relação ao controle. Os conteúdos de N, P, Ca e Mg foram influenciados pelos FMAs e pelas doses de P.

Published: July 2017

As dimensões do recipiente afetam tanto o custo de produção quanto a qualidade das mudas de espécies florestais, e o padrão de resposta destas é dependente da especificidade da espécie. Objetivou-se com o presente estudo avaliar o efeito do tamanho de recipientes no crescimento inicial das espécies florestais Mezilaurus itauba Taub. ex Mez e Platymiscium ulei Harms. Foram conduzidos dois experimentos concomitantemente, em condições de viveiro, utilizando-se o delineamento experimental inteiramente casualizado, com cinco repetições. Os tamanhos de recipientes testados equivaleram-se a 20 x 15 cm (T1); 20 x 20 cm (T2); 23 x 20 cm (T3); 25 x 20 cm (T4); 30 x 20 cm (T5) e 33 x 23 cm (T6). Aos 90 dias após o transplantio das plântulas, verificou-se que o tamanho de recipientes afeta, de maneira diferenciada, a qualidade das mudas tanto de macacaúba quanto de itaúba. Sendo o recipiente 25 x 20 cm mais indicado para o cultivo da espécie macacaúba, enquanto que para a itaúba recomenda-se o recipiente de dimensões 33 x 23 cm. Por outro lado, os recipientes 20 x 15 cm e 20 x 20 cm não devem ser utilizados para nenhuma das espécies avaliadas.

Published: July 2017

A castanheira-da-amazônia (Bertholletia excelsa Bonpl.) é uma espécie exigente de luz, pois em floresta nativa, a espécie depende da formação de clareiras para alcançar o tamanho reprodutivo e em plantios florestais demonstra rápido crescimento inicial quando exposta a altos níveis de irradiância. No entanto, os aspectos ecofisiológicos dessa espécie sob condições contrastantes de irradiância não foram investigados. Nesse estudo, além das características de crescimento, objetivou-se analisar pela primeira vez o grau de plasticidade das respostas ecofisiológicas de Bertholletia excelsa quando submetida a ambientes de irradiância contrastantes. Plantas jovens de Bertholletia excelsa foram cultivadas em três condições de irradiância: baixa (20-300 µmol m-2 s-1), moderada (800-1000 µmol m-2 s-1) e alta (1900-2100 µmol m-2 s-1). Foram analisadas características de crescimento, trocas gasosas, teores de pigmentos cloroplastídicos e, no fim do experimento, o acúmulo e partição de biomassa. Plantas jovens de Bertholletia excelsa demonstraram maior acúmulo de biomassa, crescimento e fotossíntesequando expostas aos ambientes de moderada e alta irradiância. A condição de baixa irradiância estimulou maior partição de biomassa para a parte aérea em contraposição ao sistema radicular e maior concentração foliar de pigmentos cloroplastídicos. Bertholletia excelsa possui plasticidade fisiológica sob condições contrastantes de irradiância, sendo o maior crescimento e acúmulo de biomassa, em ambientes de moderada e alta irradiância, promovidos pelo melhor desempenho fotossintético, ao passo que o balanço positivo de carbono sob baixa irradiância é assegurado pelo investimento em estruturas de interceptação e captação de energia.

Objetivou-se com este trabalho avaliar o desempenho e determinar os custos de dois sistemas de cabos aéreos na extração de madeira de eucalipto em região montanhosa. A análise técnica baseou-se em estudo de tempos e movimentos do ciclo operacional e produtividade de dois sistemas de extração: Sistema 1 (trator Massey Ferguson 297 e guincho Penzsaur K301-T) e Sistema 2 (escavadora Caterpillar 320L e guincho Koller), operando em plantios com idade de sete anos e de segunda rotação. A produtividade média na extração de madeira foi de 13,63 m3 h-1 para o Sistema 1 e 14,70 m3 h-1 para o Sistema 2, para distância média de 150 m, eficiência operacional de 46% e 51% e disponibilidade mecânica de 91% e 59%, respectivamente. O aumento da distância de extração implicou em aumento no tempo para realizar as atividades do ciclo operacional e em redução da produtividade. O Sistema 2 mostrou-se mais produtivo, porém, apresentou maior custo de produção.

In order to learn more about consumer and the process of buying green products, it becomes necessary not only to identify the profile of environmentally responsible consumer, but also to develop and apply relevant metrics about your environmentally conscious behavior. This research aims to analyze the relationships and the possible gap between attitude and behavior intention to purchase green products among Brazilian university management area. The study is quantitative in nature and is descriptive of your goals. This is a field study using the technique of Structural Equation Modeling. The results confirmed the positive relationship between attitude and intention to buy green products, as well as the positive relationship between intention and behavior, although less expressive. The influence of availability, perceived price and quality between intention and purchase behavior was also confirmed. Despite differences in the influence of the constructs, was noted that the price realized is a predominant variable during the transition between intention and purchase behavior of green products. Expected to contribute to the generation of discussions about procurement of green products, stimulate the development of new research, and assist in developing marketing strategies based on the behavior of their consumers.

The paper analyzed the effectiveness of the Food Acquisition Program (FPA) as a public policy of local development, in densify the level of social capital in four cities in the state of Minas Gerais. Data was collected by conducting semi-structured interviews with several segments of actor involved in the implementation and operation of the FPA, subsequently categorized and analyzed by operating categories of social capital previously defined. Results indicated that the analyzed regions have low levels of social capital. Moreover, the existence of operational biases in the design and implementation of the FPA, notably in relation to deficiency in government communication among all the actors involved and the limited function of collective organizations, favors the perpetuation of the status quo. Thus, the modern model of the government intervention, arising with implementation the FPA, not have been transformer in relation to local development, in the cities studied. This scenario, however, can be changed when there is support from the municipal government and the existence of local leaders among the beneficiaries.

Among the methods of control, using biological strains of Bacillus thuringiensis israelensis (Bti) has stood out for its efficiency and security in the application. This study aimed to evaluate the efficiency of Bti to control the population of the Aedes aegypti mosquito in junkyards  and recycling centers of Chapecó, Santa Catarina. Seven applications of Bti were conducted once every 21 days, three junkyards and three recycling centers, from August to December 2014. Was used wettable powder, soluble in water and applied at a concentration of 800 grams per hectare according to the manufacturer's technical specifications. The monthly number of larvae and of eggs and larvae of A. aegypti were recorded and compared with the results obtained in junkyards and recycling control. It was observed a reduction of 89.6% in the number of eggs and mosquito larvae in establishments that received treatment with Bti, compared to the establishments control. The infestation occurred two months earlier in establishments that did not receive treatment. The Bti was efficient in the mosquito A. aegypti population control in junkyards and recycling centers in tested conditions. It is presented as an alternative for the prevention of dengue, chikungunya and zika virus.

This study aimed to determine the atmospheric and oceanic patterns related to changes in precipitation over the Amazon basin during the episodes of extreme drought occurred in the years of 1982/83, 2004/2005 and 2009/10. Data from the zonal and meridional components of the wind vector, wind speed, omega, specific humidity, precipitation and sea surface temperature was used. The data was obtained from the reanalysis-2 NCPE/NCAR (except for the variable precipitation which was obtained from the CMAP). The anomalous composition method was used to determine the atmospheric and ocean fields that were characteristic of episodes of intense drought. The results show a deficit in rainfall in the rainy pre-season (SON) in part of the northern region of South America and northeastern Brazil. The lower level of rainfall also persists during the rainy season (December to April). Associated with these anomalous patterns of rainfall, positive anomalies of SST were observed which were similar to El Niño events, followed by anomalous subsidence in the Amazon. In the rainy pre-season, wind divergence over the state of Amazonas and the north of South America was observed. During the rainy season, the divergence in streamlines shows the weakening of the northeast trade winds. In addition, the anomalous divergence of vertically integrated moisture flux reveals consistency with rainfall deficits in theipre and rainy season in the Amazon basin.

This study aimed to carry out the rural environmental registration and benchmarking between Law No. 4771 of October 15, 1965 (old Forest Code) and Law No. 12651 of May 25, 2012 (current Forest Code). The study area constitutes a property, located in the north of the Rio Grande do Sul state, ith an area of 49.77 hectares, representing 2.48 tax modules. Identified were 14 classes of use and land cover, which were divided into two classes, the anthropic use and natural use. Use areas were found restricted in springs, river banks and plated for the two laws. Areas edge plated found to the old forestry code and areas of restricted use for the current forest code. The use of data crossing and land cover and PPAs showed some flexibility in relation to the current forest code which extinguishes 7.11 hectares in PPAs, 14.22% of the total area. In the property 3.91 hectares belonged to areas of anthropic use and 3.17 hectares of natural areas use. The application of the transitional rules and new concepts covered by Law No. 12,651/12 may contribute to this effect.

The water quality of a river basin dependent on numerous factors, whether natural or anthropogenic. Thus, this research aims to analyze the water quality parameters and the influence of land use and land cover in the watershed of Abaúna Rio, Brazil. The methodology made it possible to analyze the aquatic and terrestrial environment so as to achieve integration between the different uses and land cover and water parameters. For this, we used the satellite image Landsat 8, for that survey land use and land cover. The water parameters were: total suspended solids (TSS), water temperature (Temp.); hydrogen potential (pH); dissolved oxygen (DO), turbidity and total coliforms. From the integrated assessment of aquatic and terrestrial environment, it was found that water most collection points falls within the rules of CONAMA, but not for human consumption and it became clear that the uses are not in accordance with the rules of Federal Forest code. Therefore, the uses are interfering in water quality by altering the physical, chemical and bacteriological. For the improvement of the entire watershed water quality it is important to implement the use of alternative and land cover for the preservation and restoration of riparian forest.

The present paper aimed to evaluate the size sediment effects on runout area damaged by debris flow by using Kanako-2D in Böni Watershed, Serra Gaucha. This watershed presents a vast history of natural disasters, highlighting the events occurred in 1982 and 2000. The sediment sizes considered in the simulations and evaluated in terms of erosion, deposition and reached area were 0.15, 0.30, 0.50, 1.0, 1.3, 2.0 and 3.0 m. The sediment size strongly influenced on the erosion, deposition and total area reached by debris flow. Fine-grained sediments presented higher mobility, traveling greater distances and reaching larger areas than coarse-grained sediments. The obtained results confirm that Kanako-2D can be an important tool to predict susceptible areas to debris flow.
History representations and interpretations in contemporary Lithuanian theatre
Authors: Steiblytė Kristina
Published: July 2017

The text deals with (re)interpretations of history in professional contemporary Lithuanian theatre.According to historians, nowadays there are few dominating narratives about Lithuanian history: the history of the Grand Duchy of Lithuania with the grand dukes in the forefront, the only Lithuanian king Mindaugas, and the history of the 20th century wars, occupation ant battles for independence. Based on that, the text provides an attempt to figure out how these narratives are represented and reinterpreted in contemporary Lithuanian theatre with the 20th century stories dominating the repertory of historic performances. Those are both confirming the predominant narratives and reinterpreting them and establishing new relation with personalities and events dominant in memory politics. The text also deals with the narrative of the victim that dominates historic Lithuanian self-perception. Two performances help as examples understanding how this narrative can be strengthened or criticised. The last part of the text presents the place that Polish, Russian and Jewish minorities get in contemporary Lithuanian theatre to represent their versions of history and asks whether contemporary Lithuanian theatre is contributing to the creation of a more involving social environment.
Minimal-assumption inference from population-genomic data
Authors: Weissman Daniel B , Hallatschek Oskar
Published: July 2017

Samples of multiple complete genome sequences contain vast amounts of information about the evolutionary history of populations, much of it in the associations among polymorphisms at different loci. We introduce a method, Minimal-Assumption Genomic Inference of Coalescence (MAGIC), that reconstructs key features of the evolutionary history, including the distribution of coalescence times, by integrating information across genomic length scales without using an explicit model of coalescence or recombination, allowing it to analyze arbitrarily large samples without phasing while making no assumptions about ancestral structure, linked selection, or gene conversion. Using simulated data, we show that the performance of MAGIC is comparable to that of PSMC’ even on single diploid samples generated with standard coalescent and recombination models. Applying MAGIC to a sample of human genomes reveals evidence of non-demographic factors driving coalescence.
Treatment-emergent hypomania possibly associated with over-the-counter supplements
Authors: Olsufka William , Abraham Mary-Ann
Published: July 2017

The use of complementary and alternative medicine (CAM) is gaining popularity in the Western world. Among the general public, CAM is often perceived to be associated with less stigma, fewer adverse effects, and may be more affordable. A number of patients utilize CAM for the treatment of depression; however, as there is limited scientific evidence, the safety profile of these supplements are largely unknown. In this case, a 42-year-old man developed hypomania approximately 1 week after S-adenosylmethionine (SAMe) and 5-hydroxytryptophan (5-HTP) therapy was initiated for depression. The combination of SAMe and 5-HTP can potentially induce hypomanic episodes.

Modulation of intracellular guanosine 3′,5′‐bispyrophosphate ((p)ppGpp) level, the effector of the stringent response, is crucial for survival as well as optimal growth of prokaryotes and, thus, for bacterial pathogenesis and dormancy. In Mycobacterium tuberculosis (Mtb), (p)ppGpp synthesis and degradation are carried out by the bifunctional enzyme MtRel, which consists of 738 residues, including an N‐terminal hydrolase‐ and synthetase‐domain (N‐terminal domain or NTD) and a C‐terminus with a ribosome‐binding site. Here, we present the first crystallographic structure of the enzymatically active MtRel NTD determined at 3.7 Å resolution. The structure provides insights into the residues of MtRel NTD responsible for nucleotide binding. Small‐angle X‐ray scattering experiments were performed to investigate the dimeric state of the MtRel NTD and possible substrate‐dependent structural alterations.

Chondrosarcoma is the second most common primary malignancy form of bone cancer, exhibiting resistance to chemotherapy and radiation therapy as well as developing high metastasis ability in late‐stage tumors. Thus, understanding the metastatic processes of chondrosarcoma is considered a strategy for the treatment of this disease. Sphingosine 1‐phosphate (S1P), a bioactive sphingolipid, is produced intracellularly by sphingosine kinase (SphK) and is regarded as a second signaling molecule that regulates inflammation, proliferation, angiogenesis, and metastasis. However, the effect of S1P on chondrosarcoma remains uncertain. As demonstrated by the transwell, immunoblotting, and real‐time PCR analyses, we found that S1P inhibited cell migration and MMP‐2 expression through the upregulation of the tissue inhibitor of metalloproteinase‐3 (TIMP‐3) expression in human chondrosarcoma cells. Additionally, we also showed that microRNA (miRNA)‐101, which targets the 3′ untranslated region (3′UTR) of TIMP‐3, decreased significantly following S1P treatment. After transfection with miR‐101 mimics, the S1P‐regulated cell migration and TIMP‐3 expression were both reversed. Furthermore, we also showed that the S1P‐inhibited cell migration is mediated through the c‐Src/MEK/ERK signaling axis. Meanwhile, the in vivo study indicated that overexpression of SphK1 decreases chondrosarcoma metastasis to the lungs. Our results illustrate the clinical significance between SphK1, TIMP‐3, and miR‐101 in human chondrosarcoma patients. Taken together, our results suggest that S1P and miR‐101 may prove to be potential therapeutic targets for future chondrosarcoma treatment.

None of the clinically relevant gene expression signatures available for breast cancer were specifically developed to capture the influence of the microenvironment on tumor cells. Here, we attempted to build subtype‐specific signatures derived from an in vitro model reproducing tumor cell modifications after interaction with activated or normal stromal cells. Gene expression signatures derived from HER2+, luminal, and basal breast cancer cell lines (treated by normal fibroblasts or cancer‐associated fibroblasts conditioned media) were evaluated in clinical tumors by in silico analysis on published gene expression profiles (GEPs). Patients were classified as microenvironment‐positive (μENV+ve), that is, with tumors showing molecular profiles suggesting activation by the stroma, or microenvironment‐negative (μENV−ve) based on correlation of their tumors' GEP with the respective subtype‐specific signature. Patients with estrogen receptor alpha (ER)+/HER2−/μENV+ve tumors were characterized by 2.5‐fold higher risk of developing distant metastases (HR = 2.546; 95% CI: 1.751–3.701, P = 9.84E‐07), while μENV status did not affect, or only suggested the risk of distant metastases, in women with HER2+ (HR = 1.541; 95% CI: 0.788–3.012, P = 0.206) or ER‐/HER2− tumors (HR = 1.894; 95% CI: 0.938–3.824; P = 0.0747), respectively. In ER+/HER2− tumors, the μENV status remained significantly associated with metastatic progression (HR = 2.098; CI: 1.214–3.624; P = 0.00791) in multivariable analysis including size, age, and Genomic Grade Index. Validity of our in vitro model was also supported by in vitro biological endpoints such as cell growth (MTT assay) and migration/invasion (Transwell assay). In vitro‐derived gene signatures tracing the bidirectional interaction with cancer activated fibroblasts are subtype‐specific and add independent prognostic information to classical prognostic variables in women with ER+/HER2− tumors.
Detection of earthquake swarms at subduction zones globally: Insights into tectonic controls on swarm activity
Authors: Nishikawa T. , Ide S.
Published: July 2017

Earthquake swarms are characterized by an increase in seismicity rate that lacks a distinguished main shock and does not obey Omori's law. At subduction zones, they are thought to be related to slow‐slip events (SSEs) on the plate interface. Earthquake swarms in subduction zones can therefore be used as potential indicators of slow‐slip events. However, the global distribution of earthquake swarms at subduction zones remains unclear. Here we present a method for detecting such earthquake sequences using the space‐time epidemic‐type aftershock‐sequence model. We applied this method to seismicity (M ≥ 4.5) recorded in the Advanced National Seismic System catalog at subduction zones during the period of 1995–2009. We detected 453 swarms, which is about 6.7 times the number observed in a previous catalog. Foreshocks of some large earthquakes are also detected as earthquake swarms. In some subduction zones, such as at Ibaraki‐Oki, Japan, swarm‐like foreshocks and ordinary swarms repeatedly occur at the same location. Given that both foreshocks and swarms are related to SSEs on the plate interface, these regions may have experienced recurring SSEs. We then compare the swarm activity and tectonic properties of subduction zones, finding that swarm activity is positively correlated with curvature of the incoming plate before subduction. This result implies that swarm activity is controlled either by hydration of the incoming plate or by heterogeneity on the plate interface due to fracturing related to slab bending.
