Pulmonary venous abnormalities encountered on pre-radiofrequency ablation mapping multidetector computed tomography
Authors: Cronin Paul , Kelly Aine M.
Published: July 2017

Multidetector computed tomography (MDCT) elegantly renders pulmonary venous anatomy. With increasing numbers of radiofrequency ablation procedures being performed, there is now a greater emphasis on pre-procedure imaging to delineate this anatomy. Pulmonary venous mapping studies can be performed with or without ECG-gating. However, ECG-gating improves both the quality of 3D images and the accuracy of pulmonary vein (PV) ostial diameter measurements. Including the superior thorax, and not just the left atrium and central PVs, allows visualization of aberrant pulmonary venous drainage to the brachiocephalic veins or superior vena cava. Normally, there are two superior PVs, one right and one left, and two inferior PVs, one right and one left. The right superior vein usually drains the right upper and middle lobe. The left superior vein drains the left upper lobe including the lingula. The inferior veins drain their respective lower lobe. PV anatomy is more variable than pulmonary arterial anatomy, and developmental anomalies are common. This article describes, illustrates and reviews the common anomalies of the PVs in our experience performing over 1000-pre-radiofrequency ablation cardiac MDCT studies. The commonest anomalies are supernumerary or accessory veins (on the right) and a (left) common trunk. More rarely, partial anomalous pulmonary venous return and Cor triatriatum are seen, and rarest of all is total anomalous pulmonary venous return, PV varix and single or multiple vein stenosis or atresia.

Authors: Malik Garima , Dhull Anil , Atri Rajeev , Kaushal Vivek
Published: July 2017

Context: Head and neck cancers (HNCs) include malignancies of oral cavity, nasopharynx, oropharynx, hypopharynx, larynx, paranasal sinuses, and major and minor salivary glands. Worldwide incidence of HNC cases is 4.8%, whereas in India, it is 14.3%.

Aims: Evaluation and comparison of the efficacy, tolerability, and toxicity of neoadjuvant chemotherapy (NACT) with docetaxel, carboplatin, and 5-fluorouracil (TPF) followed by concomitant chemoradiation in one group, accelerated radiation therapy (RT) in second group, and conventional RT in third group.

Subjects and Methods: The present randomized prospective study was conducted on locally advanced head and neck carcinoma patients who were randomly divided into three groups. All patients received NACT with 3-weekly TPF, for 3-courses. Group I-patients received concomitant conventional RT, 64 Gy/32 fractions/6.2-week along with three weekly carboplatin 300 mg/m2 × 3-cycles. Group II-patients received accelerated RT given six fractions per week, total dose 64 Gy/32 fractions/5.2-week. Group III-patients received conventional RT, 64 Gy/32 fractions/6.2-week.

Results: The overall response rate to NACT was 100% in all groups. At last follow-up, in Group I – 52% remained alive with no evidence of disease (NED), 39% remained alive with residual disease, and 9% had locoregional recurrence. In Group II – 46% remained alive with NED, 46% remained alive with disease, 8% had locoregional recurrence, whereas in Group III – 40% remained alive with NED, 44% remained alive with disease, and 16% had locoregional recurrence.

Conclusions: NACT followed by concomitant chemoradiation is a better treatment protocol as compared to accelerated RT or conventional radiotherapy, in terms of better complete response rates with acceptable toxicity profile.
Primary epithelioid sarcoma of scalp
Authors: Gurwale Sushma , Gore Charusheela , Kaur Supreet , Deshpande Anjali
Published: July 2017

Epithelioid sarcoma (ES) is a rare mesenchymal tumor of unknown histogenesis which displays multidirectional differentiation, predominantly epithelial. They have no normal cellular counterpart and differ from both synovial sarcoma and other carcinomas. It mainly affects young adults. It has two variants, classic type and proximal type. The more common classic type presents as a slowly growing painless nodule or plaque on the distal extremities. It is rare in children and older individuals. There is male predominance. The size varies from few millimeters to several centimeters. Central deeply seated lesions in pelvis and genital tract are termed as proximal ES. It has a multinodular growth pattern and usually occurs in older patients. These are comparatively more aggressive and metastasize early. On histopathological examination, these lesions need to be distinguished from other tumors showing epithelioid morphology. Primary ES of scalp is an exceedingly rare tumor. We present a case of nodular tumor on the scalp with cervical lymph node metastasis.
Analysis of prostaglandin-endoperoxide synthase-2 gene polymorphisms and risk of cervical cancer in an East Indian population: A case–control study
Authors: Sur Dipanshu , Chakravorty Ratnabali
Published: July 2017

Background: The prostaglandin-endoperoxide synthase-2 (PTGS-2) gene appears to play a role in inflammation or tumor and mitogenesis. Genetic polymorphisms in PTGS-2 might contribute to differential PTGS-2 expression and subsequent interindividual variability in susceptibility to cancer.

Aim: The goal of this study is to identify genetic variants of PTGS-2 gene in women of East India, which may associate with risk of cervical cancer.

Materials and Methods: We enrolled 200 histopathologically confirmed patients with cervical cancer (age 18–60 years) (cases) and their corresponding sex-matched 200 normal individuals (controls). To identify genetic variants responsible for cervical cancer, we performed sequence analysis of PTGS-2 genes. Questionnaire survey was conducted to comprehend the demographic data, smoking status, and cancer stage of patients.

Results: The genotype frequency of rs689466 polymorphism was significantly different between case and control groups (P < 0.001). Compared with the wild-type genotype AA, the variant genotype GG was associated with 20-fold increased risk (P < 0.001; odds ratio = 20.76; 95% confidence interval [CI]: 2.86–160.73) for cancer patients. The rs5275: exon1-+837T>C polymorphism was not associated with cancer risk although this allele was correlated with decreased risk (P = 0.701; odds ratio = 0.71; 95% CI: 0.26–1.90). CC genotype was more frequently found in controls as compared with cases and showed an inverse association with the development of cervical cancer, thus suggesting a possible protective effect.

Conclusions: PTGS-2 genotype rs689466: —1195A/G gene polymorphism demonstrated strongly associated with cervical cancer disease. However, exon1-+837T > C polymorphism was not associated with cancer risk in East Indian women. Further studies evaluating the role of PTGS-2 gene polymorphisms in ethnically diverse populations and a larger cohort may help in understanding the etiopathogenesis of cervical cancer in women worldwide.

Authors: Carman Aubri S. , John Chandy C.
Published: July 2017

The Benjamin H. Kean Fellowship in Tropical Medicine is an American Society of Tropical Medicine and Hygiene initiative that provides medical students with funding for international clinical or research experiences lasting at least 1 month. Of the 175 Kean fellows from 1998 to 2013, 140 had current available e-mails, and 70 of the 140 (50%) responded to a survey about their fellowship experience. Alumni indicated that the Kean Fellowship had a high impact on their career plans with regard to preparation for (N = 65, 94.2%) and inspiration to pursue (N = 59, 88.1%) a career in tropical medicine and global health. Continued involvement in tropical medicine and global health was common: 52 alumni (74.3%) were currently working in tropical medicine or global health, 49 (71.0%) had done so in the interim between the Kean fellowship and their current position; and 17 of 19 Kean fellows (89.4%) who had completed all medical training and were now in professional practice continued to work in tropical medicine and global health. Alumni had been highly productive academically, publishing a total of 831 PubMed-indexed manuscripts, almost all on tropical medicine or global health topics, in the period between their fellowship year and 2013. Alumni reported strengths of the fellowship including funding, networking, and flexibility, and suggested that more networking and career mentoring would enhance the program. The Benjamin H. Kean fellowship program has been highly successful at inspiring and fostering ongoing work by trainees in tropical medicine and global health.
Adaptation of the Four Forms of Employee Silence Scale in a Polish sample
Authors: Adamska Krystyna , Jurek Paweł
Published: July 2017

Background

Silence is understood as a decision not to speak up in situations of observed irregularities both in productivity and ethics. The study examined the validity of the Four Forms of Employee Silence Scale (FFESS) in the Polish population. The scale is a four-factor measure designed to capture differently motivated tendencies to be silent in organizations. The scale distinguishes acquiescent, quiescent, prosocial and opportunistic silence. Employee silence has been linked to many important individual outcomes: failure to react to ethical transgressions, stress and depression, and lower creativity and productivity.

Participants and procedure

A total of 1044 employees of various organizations working for at least six months at a given position provided the responses for the validation study.

Results

The results confirmed the superiority of the four-factor model shown by adequate fit indexes: The FFESS has adequate internal consistency at both the scale and item levels. The criterion-related validity of the scale was established by correlating four forms of silence with measures of emotional attitude toward organization, procedural justice, relational contract and turnover intention.

Conclusions

The four forms of employee silence are empirically distinct concepts in the Polish sample. The scale may be used as the measurement of individual differences. It can also serve as a tool for diagnosing a climate of silence in an organization.
A construção do conhecimento organizacional segundo a abordagem da semiótica peirceana

Objetivo. Apresentar uma contribuição inicial da explicação da Semiótica Peirceana sobre o processo de construção de conhecimento em organizações. Método. No estudo utilizou-se a pesquisa exploratória com apoio de revisão bibliográfica acerca do assunto. Resultados. A aplicabilidade da Fenomenologia e da Semiótica nas organizações, na qual os sujeitos se relacionam por meio de troca sígnica partilhando linguagem. Pode-se afirmar que os conceitos propostos por Peirce permanecem úteis à análise teórica do conhecimento. Conclusões. O presente estudo possibilitou explanar sobre a criação de significao nas organizações, que acontece em detrimento da necessidade de respostas às mudanças nas situações cotidianas e possibilita a transformação do conhecimento tácito em conhecimento explícito. No entanto, para que este processo tenha efetividade, é necessário reconhecer que a criação do conhecimento deve pautar-se pelo teste pragmático das representações geradas e da formação de novos hábitos mentais.
La función parlamentaria de control a caballo de parlamentarismo y presidencialismo
Authors: García Roca Javier
Published: July 2017

Es posible comparar presidencialismo y parlamentarismo en los controles parlamentarios. Sin control parlamentario, no puede existir democracia representativa, tampoco en el presidencialismo. Las normas constitucionales y de los Reglamentos ya reflejan esa tendencia en Iberoamérica. Esta conclusión lleva a que el clásico debate sobre ambos sistemas de gobierno deba contemplarse de una manera distinta. Hay una pluralidad de tipos presidenciales y semipresidenciales de confusa diferenciación en la realidad. El presidencialismo originario estadounidense es antiguo y difícilmente exportable. El presidencialismo iberoamericano contemporáneo se ha ido parlamentarizando. Existe actualmente un continuum en el binomio presidencialismo/parlamentarismo con diferencias de grado más que cualitativas. Se advierten tres tendencias: la presidencialización del parlamentarismo europeo, la parlamentarización del presidencialismo iberoamericano, e influencias recíprocas entre los Reglamentos parlamentarios. Pluripartidismo extremado, representación proporcional, y un entendimiento absolutista de la separación de poderes presidencial, que impida los controles parlamentarios, son rasgos incompatibles. La solución más fácil está en abandonar ese entendimiento absolutista que no garantiza bien constitucional alguno. La duración fija del mandato presidencial y la idea de que el Presidente debe responder de forma diferida y directa ante el electorado hacen imposible mecanismos de control-responsabilidad política de su figura, pero puede bastar con reforzar los de control-fiscalización para construir checks and balances y representación política en el Parlamento.*

Published: July 2017

Introduction: Underdiagnosis of COPD seems to be a relevant clinical and social problem. We hypothesized that active public spirometry campaign may help identify subjects with airflow limitation consistent with COPD. The aim of the study was (1) to evaluate the willingness of random smokers to undergo public spirometry, (2) to assess the ability to obtain an acceptable quality spirometry during a public campaign, and (3) to assess the relationships between the presence and severity of respiratory symptoms and readiness to undergo spirometry. Material and methods: Pedestrians aged > 40 years and a smoking history > 10 pack-years were recruited by medical students to fill a questionnaire and perform spirometry. Those with obstructive or borderline ventilatory insuffciency were invited and encouraged to undergo stationary spirometry in a pulmonary outpatient department. Results: Nine hundred and five subjects meeting the inclusion criteria were invited to the study. Only 178 subjects agreed to complete the questionnaire and undergo spirometry. Airway obstruction and borderline spirometry result (classified as possible airway obstruction) were found in 22 and 37 subjects, respectively. Of these, only 15 patients attended follow-up visit to verify public spirometry results. Extrapolation of the limited data showed the incidence of newly diagnosed airway obstruction as 10.7%. Conclusions: Public spirometry campaign does not seem to be an effective way of COPD screening. Smokers are reluctant to undergo complimentary spirometry even in the presence of pronounced respiratory symptoms. Our observations may be helpful in elaborating future screening programs for COPD.

Published: July 2017

The paper examines the impact of trust in an agricultural marketing cooperative. The aim is to
explore how the trust among members and between members and management affect the commitment of
members towards the cooperative (group cohesion) and their satisfaction with the cooperative. Trust is examined
from two dimensions: cognitive and affective. Our results have clearly proved that trust has a positive
impact on group cohesion and satisfaction. According to the experiences, however, the impact of examined
dimensions of trust is differentiated: the statistical models regarded the impact of affective dimensions on
group cohesion and members’ satisfaction more important than the impact of cognitive dimension.

The aim of this paper was comparative assessment of production potential, organization of production, economic
efficiency and investment abilities of two group of farms from the same communities that collected data for Polish Farm
Accountancy Data Network (FADN) in the years 2004-2013. The first group was farms that participated in the measure
Afforestation of agricultural land under RDP 2004-2006 (beneficiary farms), while the second group was remaining farms
that didn’t participate in this measure in the analyzed period. It was found that beneficiary farms in comparison to remaining
farms characterized smaller utilized agricultural area (UAA) lower share of rented area and higher share of own UAA with
the worst quality of soil. Moreover they had worse technical equipment of labour and lower family farm income. However,
beneficiary farms like remaining farms had positive rate of reproduction fixed assets but their scale of investment was lower.
As diferenças como ethos e práxis contemporâneos: sobre a dialética entre fundamentação e aplicação de paradigmas normativo-religiosos
Authors: Danner Leno Francisco , Bavaresco Agemir , Danner Fernando
Published: July 2017

Neste artigo, estabelecemos a categoria das diferenças como o ethos e a práxis antropológico-ontológicos e epistemológico-políticos efetivamente contemporâneos, que desafiam-dinamizam as religiões institucionalizadas e universalistas, ao estilo da Igreja Católica, em seu uso de fundamentações essencialistas e naturalizadas como base normativo-paradigmática para o enquadramento, legitimação e orientação dessas mesmas diferenças, como embasamento da dialética entre pluralidade e unidade acerca dessas mesmas diferenças. A partir disso, defenderemos que o desafio central para as religiões institucionalizadas e universalistas neste século XXI – e, no nosso caso, novamente para a Igreja Católica – consiste na desconstrução da correlação entre institucionalismo forte, objetividade antropológico-ontológica e epistemológico-moral estritas e fundamentalismo político-normativo. Nesse sentido, na medida em que também as instituições religiosas trouxerem para dentro de sua dinâmica de constituição, legitimação e fomento do credo as diferenças como práxis normativa e sujeitos epistemológico-políticos da fundamentação, alcança-se um enfraquecimento e uma moderação – e talvez até mesmo um abandono – de fundamentações essencialistas e naturalizadas como base para o enquadramento de todas as áreas da vida humana. Este, de todo modo, conforme pensamos, deve ser o caso de gênero e de sexualidade, que a rigor já não poderiam e nem deveriam mais ser fundados em tais bases essencialistas e naturalizadas.
Pedagogia para a liberdade: Notas sobre a política educacional da Reforma Protestante
Authors: Gomes-da-Silva Pierre Normando
Published: July 2017

Este artigo trata de um ensaio analítico-propositivo desenvolvido a partir de revisão teórico-bibliográfica e de levantamento histórico sobre o trato educacional construído por ocasião da Reforma Protestante. Assim, descrevemos as implicações pedagógicas da Reforma Protestante na política educacional quinhentista, destacando a proposta educacional de Martinho Lutero. Uma proposição que rompeu com a mentalidade medieval, aristocrática e feudal, por meio de dois processos: valorizando a língua germânica, a partir das traduções, publicações e criação de escolas populares vernáculas e propondo um modelo educacional fora dos parâmetros escolásticos, que era usado apenas para preparar os jovens candidatos à vida monástica. O projeto educacional protestante pensava uma escola para todos, laica, capaz de assumir a integralidade do homem em sua espiritualidade e corporeidade, superando as dicotomias entre os saberes manual e intelectual e propulsora de uma subjetividade individual e de uma consciência crítica, não submissa as instituições eclesiásticas ou civis.

As relações entre história e lingüística a partir de Robin
Authors: Petró Cleber Monticelli
Published: July 2017

Este texto tem por objetivo trazer uma análise da leitura dos quatro primeiros capítulos da obra História e Lingüística de Régine Robin (1973), onde ela mostra as discussões teóricas a partir de autores diferenciados, além de ir esclarecendo o seu próprio ponto de vista quanto a uma teoria do discurso baseada na articulação dos conceitos da história e da lingüística. Pretende-se mostrar aos historiadores que a leitura de um texto traz problemas como a produção do sentido e que não se questionar sobre isso pode acarretar grandes equívocos interpretativos.

Nossa proposta de trabalho, inscrita no projeto de iniciação científica intitulado História das Ideias Linguísticas no Sul: estudo das ideias e organização da memória dos anos 80 a 2000, é parte da investigação que vimos desenvolvendo sobre a Moderna Gramática Brasileira (1976), de Celso Pedro Luft. Filiando-nos à Análise de Discurso de linha francesa e à História das Ideias Linguísticas, mobilizamos as noções de sujeito, posição-sujeito e autoria para investigarmos como o gramático Celso Pedro Luft apropria-se de outros saberes metalinguísticos diante da emergência da Linguística nos cursos de Letras do Rio Grande do Sul, na década de 70.
REALIZAÇÕES VARIÁVEIS DE VOGAIS TÔNICAS EM PORTO ALEGRE (RS): DITONGAÇÃO OU INGLIDING?
Authors: Battisti Elisa
Published: July 2017

O presente artigo revisa a proposta de Bisol (1989, 1994, 2012) sobre a existência de verdadeiros e falsos ditongos em português, para definir se a realização vocálica variável de vogais tônicas (né~néah, aí~aíah, tudo~tuahdo) no falar de Porto Alegre (RS) é ditongação. A revisão sugere que a realização tenha representação subjacente monofonêmica, como nos ditongos falsos. Contudo, a oitiva de entrevistas sociolinguísticas mostra que o processo não é a ditongação assimilatória de Bisol. A análise acústica de dados prototípicos revela que há aumento na duração dessa realização. Há centralização da porção final da realização vocálica, o que é compatível com ingliding.
TRAGÉDIA GREGA E TEATRO CONTEMPORÂNEO? LENDO E TRADUZINDO ANTÍGONA PARA O PALCO CONTEMPORÂNEO COM O AUXÍLIO DE HÖLDERLIN
Authors: Rosenfield Kathrin , Pereira Lawrence Flores
Published: July 2017

Este artigo apresenta uma experiência tradutória que visou, de antemão, o palco, sem desconsiderar, no entanto, a questão das diversas camadas da recepção crítica, da interpretação e da tradução. Para recuperar o potencial dramático obscurecido pelas convenções cristãs, a dramaturga e o tradutor valeram-se da versão desta tragédia do poeta alemão, Friedrich Hölderlin. Esta interpretação foi inserida no contexto brasileiro de expressão corporal, numa transposição da abordagem (crítica, teórica e tradutória) para uma produção cênica que envolveu música, dança, linguagem corporal e atuação.
BIOLOGIA DE Thaumastocoris peregrinus CARPINTERO E DELLAPÉ (HEMIPTERA: THAUMASTOCORIDAE) EM DEZ ESPÉCIES DE EUCALIPTO
Authors: Smaniotto Márcia Aparecida , Da Silva Alexandre , Da Cunha Uemerson Silva , Garcia Mauro Silveira
Published: July 2017

O percevejo-bronzeado-do-eucalipto Thaumastocoris peregrinus é originário da Austrália e foi detectado no Brasil em 2008, causando danos em plantações de eucalipto. O percevejo suga a seiva, principalmente das folhas mais velhas, nas quais se formam pontos cloróticos que, posteriormente, tornam-se manchas bronzeadas. Em casos extremos pode ocorrer desfolhação. Os trabalhos sobre o comportamento do inseto ainda são escassos perante os registros de danos em plantações de eucalipto. Diante disso, avaliou-se a biologia de Thaumastocoris peregrinus em dez espécies de eucalipto, plantadas comercialmente no Rio Grande do Sul. Das espécies oferecidas para alimentação de Thaumastocoris peregrinus, Eucalyptus dunnii foi a que conferiu maior longevidade, número de adultos, ovos e viabilidade aos insetos.
REGENERAÇÃO NATURAL DE Ocotea odorifera (VELL.) ROHWER (LAURACEAE) EM FLORESTA OMBRÓFILA MISTA, PARANÁ, BRASIL
Authors: Bett Larissa Amanda , May Dayane
Published: July 2017

A limitação do conhecimento sobre a autoecologia de Ocotea odorifera (Lauraceae) nos remanescentes conservados indica a necessidade do desenvolvimento de pesquisas que forneçam subsídios para a implantação de programas de conservação. Nesse contexto, a presente pesquisa teve como objetivo avaliar a regeneração natural de Ocotea odorifera (Lauraceae), espécie ameaçada de extinção, característica da fitofisionomia Floresta Ombrófila Mista (FOM) ocorrente na Reserva Particular do Patrimônio Natural (RPPN) Uru, Lapa, Paraná, Brasil. A distribuição nacional dessa espécie foi levantada a partir de dados museológicos disponíveis em acervos online, e no Museu Botânico de Curitiba (MBM). Para análise da regeneração natural foram definidas 10 parcelas circulares com 40 m de diâmetro, contendo uma matriz de sementes no centro, totalizando 12.560 m² de área amostral. Todos os indivíduos regenerantes de Ocotea odorifera contidos nas parcelas foram georreferenciados e mensurados em altura e Diâmetro a Altura do Solo (DAS). Foi medida também a espessura de serapilheira e intensidade luminosa em cada parcela. As análises foram baseadas nos parâmetros fitossociológicos e o grau de dispersão da espécie foi avaliado por meio do Índice de Morisita (Id). O levantamento museológico revelou 867 registros de Ocotea odorifera, compilados em 47 coleções, com ocorrência em 16 estados brasileiros. A densidade da regeneração natural foi de 77,6 ind.ha-1 e o padrão de crescimento da regeneração natural demonstrou tendência para J-invertido, com maior abundância de indivíduos (44,7%) com altura até 0,50 m. A presença das árvores-matrizes na RPPN Uru esteve restrita às áreas de FOM em estágio avançado de sucessão, sendo que as unidades amostrais com serapilheira mais espessa foram aquelas com maior número de indivíduos mensurados. O reconhecimento das potencialidades ecológicas, especialmente quanto à capacidade regenerativa e os fatores que a influenciam em ambiente natural, atuam como base para ações conservacionistas que garantem a perpetuação da Ocotea odorifera.
Gênero, Classe Social e Empreendedorismo: Foco nas Estudantes Universitárias de um País Emergente

Research worldwide has identified a strong association between social class and a variety of dimensions related to entrepreneurship including entrepreneurial intention, frequency of firm foundings, growth, success and other factors. Similarly, researchers have identified an association between gender and a series of entrepreneurial behaviors and outcomes. There is however very little research considering possible interactions between social class, gender and entrepreneurship, especially outside of the US and continental Europe. Using elite versus subelite university affiliation as a proxy for social class, the present article looks at the interaction between social class and gender as it relates to several aspects of entrepreneurship in four samples summing up 14,807 responses from Brazilian undergraduates. While supporting much of the existing research on social class and entrepreneurship and gender and entrepreneurship, it identifies a number of unexpected interactions between gender, social class and correlates of entrepreneurial behaviors.

Foreign choreographers – creators of Lithuanian choreography
Authors: Šabasevičius Helmutas
Published: July 2017

The concept of Lithuanian choreography is presented considering its specifics, based on the influenceof the development of this cultural field and on the impact produced by the heritage of different cultures and artistic schools. Ballet is the latest professional branch of Lithuanian theatrical culture, and since the beginning it was closely connected with the ballet artists who came to Lithuania from abroad and worked here for a shorter or longer period. That’s why the phenomenon of Lithuanian choreography should be associated not only with the choreographers and artists born and raised in Lithuania, but also with those who came to Lithuania as guest choreographers. The main aspect which determines the Lithuanian origin of their work is the originality of choreographic concept and the creative process with a very active participation of the Lithuanian Ballet Company. Foreign choreographers enriched the repertory of Lithuanian ballet in several ways. First of all, they created ballets on the music of Lithuanian composers, and ten Lithuanian ballets were produced this way: “Lithuanian Rhapsody” by Jurgis Karnavičius (1928, Pavel Petrov), “In the Whirl of Dance” by Vytautas Bacevičius, “Jūratė and Kastytis” by Juozas Gruodis, “Matchmaking” by Balys Dvarionas (1933, Nikolaj Zverev), “The Fading Cross” by Antanas Rekašius (1966, Konstantin Bojarskij), “The Maiden and The Death” by Anatolijus Šenderovas (1982, Ülo Vilimaa), “Desdemona” by Anatolijus Šenderovas (2005, Krill Simonov), “Acid City” by Mindaugas Urbaitis (2000, Krzysztof Pastor), “Čiurlionis” by Giedrius Kuprevičius (2013, Robert Bondara), “Eglė the Queen of Grass Snakes” by Eduardas Balsys (2015, George Williamson).As interpretations of classical heritage created in close collaboration with Lithuanian ballet dancers and soloists two productions could be named: “Coppélia”by Léo Delibes (2010, Kirill Simonov) and “The Nutcracker” by Piotr Tchaikovsky (2014, Krzysztof Pastor). Five original contemporary ballet performances were created for the Lithuanian Ballet Company: “Contrasts”, “The Rite of Spring” by Igor Stravinsky and “Carmina Burana” by Carl Orff (respectively, 2000 and 2003, Xin Peng Wang), “Sisyphus” (2001, Pascal Rioult) and “Diaghilev. Phantasies” (2008, Peter Anastos). In certain cases the significant artistic input into the above-mentioned productions was made by Lithuanian visual artists: costumes by Adomas Varnas (“Lithuanian Rhapsody”) and Aleksandra Jacovskytė (“Acid City”, “The Rite of Spring”), set design and costumes by Telesforas Kulakauskas (“In the Whirl of Dance”), Adomas Galdikas (“Jūratė and Kastytis“), Stasys Ušinskas (“The Matchmaking”), Antanas Pilipavičius (“The Fading Cross”), Henrikas Ciparis (“The Maiden and the Death”), sets by Adomas Jacovskis (“Acid City”, “The Rite of Spring”, “Carmina Burana“).

Finding the optimal Bayesian network given a constraint graph
Authors: Schreiber Jacob M. , Noble William S.
Published: July 2017

Despite recent algorithmic improvements, learning the optimal structure of a Bayesian network from data is typically infeasible past a few dozen variables. Fortunately, domain knowledge can frequently be exploited to achieve dramatic computational savings, and in many cases domain knowledge can even make structure learning tractable. Several methods have previously been described for representing this type of structural prior knowledge, including global orderings, super-structures, and constraint rules. While super-structures and constraint rules are flexible in terms of what prior knowledge they can encode, they achieve savings in memory and computational time simply by avoiding considering invalid graphs. We introduce the concept of a “constraint graph” as an intuitive method for incorporating rich prior knowledge into the structure learning task. We describe how this graph can be used to reduce the memory cost and computational time required to find the optimal graph subject to the encoded constraints, beyond merely eliminating invalid graphs. In particular, we show that a constraint graph can break the structure learning task into independent subproblems even in the presence of cyclic prior knowledge. These subproblems are well suited to being solved in parallel on a single machine or distributed across many machines without excessive communication cost.
An observational study of the North Pacific storm‐track impact on the midlatitude oceanic front

Published: July 2017

A lagged Maximum Covariance Analysis is used to examine the impact of North Pacific storm‐track activity on midlatitude oceanic frontal intensity in this study. It is found that an enhanced storm track tends to intensify the oceanic frontal intensity with a lag of 1–2 months. The forcing effect of storm‐track anomalies on oceanic frontal intensity is strongest in autumn, followed by that in summer and winter, and it is weakest in spring. Moreover, the mixed layer heat budget analysis suggests that sea surface temperature anomalies (SSTAs) related to oceanic fronts are primarily attributed to the storm‐track‐induced net surface heat flux and Ekman advection anomalies, while contributions of geostrophic advection and entrainment are relatively small. In summer and autumn, the impact of net surface heat flux anomalies on SSTAs plays a more important role than that of Ekman heat transport anomalies. Whereas in winter, Ekman heat transport anomaly forcing is comparable to the net surface heat flux forcing. Anomalous turbulent heat fluxes contribute to generating net surface heat flux anomalies in those three seasons, while the shortwave radiative fluxes make a strong contribution in summer but have little impact in winter. The anomalies of both net surface heat flux and Ekman heat transport are presumed to be associated with storm‐track‐induced surface wind anomalies. Results of the present study provide observational evidences for the positive feedback between the North Pacific storm‐track activity and midlatitude oceanic frontal intensity.

Anthranilate phosphoribosyltransferase (TrpD) is involved in tryptophan biosynthesis, catalyzing the transfer of a phosphoribosyl group to anthranilate, leading to the generation of phosphoribosyl anthranilate. TrpD belongs to the phosphoribosyltransferase (PRT) superfamily and is the only member of the structural class IV. X‐ray structures of TrpD from seven species have been solved to date. Here, functional and structural characterization of a recombinant TrpD from hyperthermophilic archaeon Thermococcus kodakarensis KOD1 (TkTrpD) was carried out. Contrary to previously characterized Mg2+‐dependent TrpD enzymes, TkTrpD was found to have a unique divalent cation dependency characterized by maximum activity in the presence of Zn2+ (1580 μmol·min−1·mg−1, the highest reported for any TrpD) followed by Ca2+ (948 μmol·min−1·mg−1) and Mg2+ (711 μmol·min−1·mg−1). TkTrpD displayed an unusually low thermostability compared to other previously characterized proteins from T. kodakarensis KOD1. The crystal structure of TkTrpD was determined in free form and in the presence of Zn2+ to 1.9 and 2.4 Å resolutions, respectively. TkTrpD structure displayed the typical PRT fold similar to other class IV PRTs, with a small N‐terminal α‐helical domain and a larger C‐terminal α/β domain. Electron densities for Zn2+ were identified at the expected zinc‐binding motif, DE(217–218), of the enzyme in each subunit of the dimer. Two additional Zn2+ were found at a new dimer interface formed in the presence of Zn2+. A fifth Zn2+ was found bound to Glu118 at crystal lattice contacts and a sixth one was ligated with Glu235. Based on the TkTrpD–Zn2+ structure, it is suggested that the formation of a new dimer may be responsible for the higher enzyme activity of TkTrpD in the presence of Zn2+ ions.
Empirical modeling of T cell activation predicts interplay of host cytokines and bacterial indole

Adoptive transfer of anti‐inflammatory FOXP3+ Tregs has gained attention as a new therapeutic strategy for auto‐inflammatory disorders such as Inflammatory Bowel Disease. The isolated cells are conditioned in vitro to obtain a sufficient number of anti‐inflammatory FOXP3+ Tregs that can be reintroduced into the patient to potentially reduce the pathologic inflammatory response. Previous evidence suggests that microbiota metabolites can potentially condition cells during the in vitro expansion/differentiation step. However, the number of combinations of cytokines and metabolites that can be varied is large, preventing a purely experimental investigation which would determine optimal cell therapeutic outcomes. To address this problem, a combined experimental and modeling approached is investigated here: an artificial neural network model was trained to predict the steady‐state T cell population phenotype after differentiation with a variety of host cytokines and the microbial metabolite indole. This artificial neural network model was able to both reliably predict the phenotype of these T cell populations and also uncover unexpected conditions for optimal Treg differentiation that were subsequently verified experimentally.

The performance of herbivorous insects is greatly affected by host chemical defenses and nutritional quality. Some herbivores have developed the ability to manipulate plant defenses via signaling pathways. It is currently unclear, however, whether a herbivore can benefit by simultaneously reducing plant defenses and enhancing plant nutritional quality. Here, we show that the better performance of the whitefly Bemisia tabaci Middle East‐Asia Minor 1 (MEAM1; formerly the “B” biotype) than Mediterranean (MED; formerly the “Q” biotype) on cabbage is associated with a suppression of glucosinolate (GS) content and an increase in amino acid supply in MEAM1‐infested cabbage compared with MED‐infested cabbage. MEAM1 had higher survival, higher fecundity, higher intrinsic rate of increase (rm), a longer life span, and a shorter developmental time than MED on cabbage plants. Amino acid content was higher in cabbage infested with MEAM1 than MED. Although infestation by either biotype decreased the levels of total GS, aliphatic GS, glucoiberin, sinigrin, glucobrassicin, and 4OH‐glucobrassicin, and the expression of related genes in cabbage, MED infestation increased the levels of 4ME‐glucobrassicin, neoglucobrassicin, progoitrin, and glucoraphanin. The GS content and expression of GS‐related genes were higher in cabbage infested with MED than with MEAM1. Our results suggest that MEAM1 performs better than MED on cabbage by manipulating host defenses and nutritional quality.
