Authors: Jørgensen Peter Godsk , Jensen Magnus Thorsten , Biering‐Sørensen Tor , Mogelvang Rasmus , Fritz‐Hansen Thomas , Vilsbøll Tina , Rossing Peter , Jensen Jan Skov
Published: September 2018

Background

Type 2 diabetes mellitus is closely associated with metabolic risk factors that all contribute to impairment of the left ventricle. The implications of having type 2 diabetes mellitus with well‐controlled metabolic risk factors compared to an increasing burden of uncontrolled metabolic risk factors on left ventricular structure and function are not known.

Methods and Results

We compared patients with type 2 diabetes mellitus (n=751) with different degrees of uncontrolled metabolic risk factors present with a control group of individuals without present uncontrolled metabolic risk factors as recommended by the World Health Organization (n=80). In patients with well‐controlled metabolic risk factors, only diastolic but neither structural nor systolic measures were impaired compared to the control group: the (early diastolic mitral inflow velocity)/(atrial diastolic mitral inflow velocity) ratio (median 0.94 [interquartile range 0.80, 1.08] versus 1.11 [0.85, 1.38],
P
<0.001), lateral early diastolic myocardial velocity at the level of the mitral annulus (mean 9.6 m/s [SD 2.5] versus 10.8 [3.5],
P
<0.001) and lateral (early diastolic mitral inflow velocity)/(early diastolic myocardial velocity at the level of the mitral annulus) (7.7 [6.5, 10.2] versus 6.3 [4.9, 7.8],
P
<0.001). With an increasing burden of uncontrolled metabolic risk factors, there were increased left ventricular mass index and wall thicknesses and impaired systolic function measured as global longitudinal strain: control group −15.9 (2.0); 0 uncontrolled risk factors −15.3 (2.4); 1 to 2 −14.6 (2.8); and ≥3 −14.0 (2.8),
P
<0.001. Within the diabetes mellitus group, there were uni‐ and multivariable associations of left ventricular measures and systolic blood pressure, body mass index, hemoglobin A
1c
, and
HDL
‐cholesterol.

Conclusions

In patients with type 2 diabetes mellitus, having well‐controlled metabolic risk factors was associated with only left ventricular diastolic impairment but not with either structural or even subtle measures of systolic function. Increasing burden of uncontrolled metabolic risk factors was associated with structural and functional impairments.

Published: September 2018

Background

There is no drug therapy for abdominal aortic aneurysm (
AAA
). FAME‐2 (Fenofibrate in the Management of Abdominal Aortic Aneurysm 2) was a placebo‐controlled randomized trial designed to assess whether administration of 145 mg of fenofibrate/d for 24 weeks favorably modified circulating markers of AAA.

Methods and Results

Patients with
AAA
s measuring 35 to 49 mm and no contraindication were randomized to fenofibrate or identical placebo. The primary outcome measures were the differences in serum osteopontin and kallistatin concentrations between groups. Secondary analyses compared changes in the circulating concentration of
AAA
‐associated proteins, and
AAA
growth, between groups using multivariable linear mixed‐effects modeling. A total of 140 patients were randomized to receive fenofibrate (n=70) or placebo (n=70). By the end of the study 3 (2.1%) patients were lost to follow‐up and 18 (12.9%) patients had ceased trial medication. A total of 85% of randomized patients took ≥80% of allocated tablets and were deemed to have complied with the medication regimen. Patients’ allocated fenofibrate had expected reductions in serum triglycerides and estimated glomerular filtration rate, and increases in serum homocysteine. No differences in serum osteopontin, kallistatin, or
AAA
growth were observed between groups.

Conclusions

Administering 145 mg/d of fenofibrate for 24 weeks did not significantly reduce serum concentrations of osteopontin and kallistatin concentrations, or rates of
AAA
growth in this trial. The findings do not support the likely benefit of fenofibrate as a treatment for patients with small
AAA
s.

Cardiac Rehabilitation Participation and Mortality After Percutaneous Coronary Intervention: Insights From the Veterans Affairs Clinical Assessment, Reporting, and Tracking Program
Authors: Beatty Alexis L. , Doll Jacob A. , Schopfer David W. , Maynard Charles , Plomondon Mary E. , Shen Hui , Whooley Mary A.
Published: September 2018

Background

Cardiac rehabilitation (CR) is strongly recommended after percutaneous coronary intervention (PCI), but it is underused. We sought to evaluate CR participation variation after PCI and its association with mortality among veterans.

Methods and Results

Patients undergoing PCI between 2007 and 2011 were identified in the Veterans Affairs Clinical Assessment, Reporting, and Tracking database and followed up until January 25, 2017. We excluded patients who died within 30 days of PCI and calculated the percentage participating in ≥1 outpatient CR visits within 12 months after PCI. We constructed multivariable hierarchical logistic regression models for CR participation, clustered by facility. We estimated propensity scores for CR participation, matched participants and nonparticipants by propensity score, calculated mortality rates, and estimated the association with mortality using Cox proportional hazards models. Participation in CR after PCI was 6.9% (2986/43 319) and varied significantly by PCI facility (range, 0%–36%). After 6.1 years median follow‐up, CR participants had a 33% lower mortality rate than all nonparticipants (3.8 versus 5.7 deaths/100 person‐years; hazard ratio, 0.67; 95% confidence interval, 0.61–0.75;
P
<0.001) and a 26% lower mortality rate than 2986 propensity‐matched nonparticipants (3.8 versus 5.1 deaths/100 person‐years; hazard ratio, 0.74; 95% confidence interval, 0.65–0.84;
P
<0.001). Participants attending ≥36 sessions had the lowest mortality rate (2.4 deaths/100 person‐years; hazard ratio, 0.47; 95% confidence interval, 0.36–0.60;
P
<0.001).

Conclusions

CR participation after PCI among veterans is low overall, with significant facility‐level variation. CR participation is associated with lower mortality rates in veterans. Additional efforts are needed to promote CR participation after PCI among veterans.
The effect of age on vigilance: a longitudinal study with a precocial species
Authors: Beauchamp Guy
Published: October 2018

Vigilance allows prey species to detect predators before it is too late to escape. While the adaptive value of vigilance has become clearer over the years, developmental questions have attracted little attention. I explored the effect of age and group size on vigilance in a precocial species, the domestic fowl (Gallus gallus domesticus). I recorded vigilance in groups of various sizes in juveniles and one year later in adults. Vigilance decreased with group size in juveniles and to a lesser extent in adults. Juveniles tested alone showed longer feeding and vigilance bouts than adults reflecting their inexperience with predation threats and more rapid satiation, respectively. Adults in larger groups were more vigilant reflecting the need to monitor aggressive conspecifics in addition to predators. Gradual acquisition of information about risk posed by predators and conspecifics and feeding constraints influenced the expression of vigilance as a function of age in this species.
A new fossil green lacewing (Neuroptera: Chrysopidae) from the early Eocene Driftwood Canyon, Canada
Authors: ARCHIBALD S. BRUCE , MAKARKIN VLADIMIR N.
Published: September 2018

Lithochrysa borealis sp. nov. (Neuroptera: Chrysopidae: Nothochrysinae) is described from the early Eocene locality at Driftwood Canyon (British Columbia, Canada). The forewing venation of the new species is similar to that of the late Eocene L. wickhami (Cockerell, 1914) from Florissant (Colorado, U.S.A.), but is distinguished from it by a slightly longer intramedian cell and distinctly longer branches of RP to CuA between the pseudocubitus and the posterior margin.
On the Inverse Relationship between the Boreal Wintertime Pacific Jet Strength and Storm-Track Intensity
Authors: Zhao Yuan-Bing , San Liang X.
Published: October 2018

Previous studies show that in boreal winters when the Pacific jet is extremely strong, the Pacific storm track is, however, unexpectedly weak. Using a recently developed technique, namely, the multiscale window transform (MWT), and the MWT-based localized multiscale energetics analysis, we investigate in this study the underlying mechanism of this counterintuitive phenomenon, based on ERA-40 data. It is found that most of the synoptic storms are generated at latitudes far north of the jet core, which lowers the relevance of the jet strength to the storm-track intensity, and the inverse relationship between the Pacific jet strength and storm-track intensity is mainly attributed to the internal dynamics. In the strong jet state, on one hand, the jet is narrow, and thus the jet winds at high latitudes are weak, resulting in weak baroclinic instabilities and hence reduced eddy growth rate; on the other hand, although baroclinic instabilities are strong at the jet core, inverse kinetic energy (KE) cascades are even stronger (by 43%). The resultant effect is that more eddy energy is transferred back to the background flow, leaving an overall weak storm track in a strong Pacific jet. In addition, diabatic processes are found to account for the inverse relationship: it is greatly weakened (by 25%) in the strong-core jet state. Apart from these, we also find that the role that barotropic canonical transfer plays in the inverse relationship is opposite to that in the formation of the midwinter minimum (MWM), another counterintuitive phenomenon in the Pacific storm track.
Progress toward the Application of a Localized Particle Filter for Numerical Weather Prediction
Authors: Poterjoy Jonathan , Wicker Louis , Buehner Mark
Published: October 2018

A series of papers published recently by the first author introduce a nonlinear filter that operates effectively as a data assimilation method for large-scale geophysical applications. The method uses sequential Monte Carlo techniques adopted by particle filters, which make no parametric assumptions for the underlying prior and posterior error distributions. The filter also treats the underlying dynamical system as a set of loosely coupled systems to effectively localize the effect observations have on posterior state estimates. This property greatly reduces the number of particles—or ensemble members—required for its implementation. For these reasons, the method is called the local particle filter. The current manuscript summarizes algorithmic advances made to the local particle filter following recent tests performed over a hierarchy of dynamical systems. The revised filter uses modified vector weight calculations and probability mapping techniques from earlier studies, and new strategies for improving filter stability in situations where state variables are observed infrequently with very accurate measurements. Numerical experiments performed on low-dimensional data assimilation problems provide evidence that supports the theoretical benefits of the new improvements. As a proof of concept, the revised particle filter is also tested on a high-dimensional application from a real-time weather forecasting system at the NOAA/National Severe Storms Laboratory (NSSL). The proposed changes have large implications for researchers applying the local particle filter for real applications, such as data assimilation in numerical weather prediction models.
Mimetic Interpolation of Vector Fields on Arakawa C/D Grids
Authors: Pletzer Alexander , Hayek Wolfgang
Published: October 2018

Interpolation methods for vector fields whose components are staggered on horizontal Arakawa C or D grids are presented. The interpolation methods extend bilinear and area-weighted interpolation, which are widely used in Earth sciences, to work with vector fields (essentially discretized versions of differential 1-forms and 2-forms). The interpolation methods, which conserve the total flux and enforce Stokes’ theorem to near-machine accuracy, are a natural complement to discrete exterior calculus and finite element exterior calculus discretization methods.
Hypoxia‐induced pulmonary vasoconstriction of intra‐acinar arteries is impaired in NADPH oxidase 4 gene‐deficient mice
Authors: Murtaza Ghulam , Paddenberg Renate , Pfeil Uwe , Goldenberg Anna , Mermer Petra , Kummer Wolfgang
Published: October 2018

We show that genetic deficiency of the reactive oxygen species generating enzyme NADPH oxidase 4 (NOX4) impairs hypoxic pulmonary vasoconstriction in small (25–40 µm) intra‐acinar, but not pre‐acinar, arteries in murine precision cut lung slices. These data suggest an involvement of NOX4 in ventilation‐perfusion matching at the acinar level.

ATITUDES, CRENÇAS E (AUTO)AVALIAÇÃO LINGUÍSTICA DE COMUNIDADES RURAIS DO 3º DISTRITO DE NOVA FRIBURGO
Authors: Dália Jaqueline De Moraes Thurler
Published: October 2018

Este artigo é parte da tese que investigou, no âmbito da Sociolinguística, a variedade dialetal das comunidades rurais do 3º Distrito de Nova Friburgo, partindo da hipótese de que nela havia uma arquicomunidade de fala. Seu objetivo se concentra em compreender como os próprios falantes avaliam a sua variedade e como a veem frente a outra considerada de prestígio, levando em conta que o julgamento linguístico é carregado de valores simbólicos que contribuem para a valorização ou para a estigmatização de um grupo de falantes. Para tanto, foram realizadas 39 entrevistas com moradores, sendo 19 da faixa etária 1 (entre 35 e 50 anos) e 20 da faixa etária 2 (entre 14 e 18 anos); 20 mulheres e 19 homens. Os resultados demonstraram que a juventude domina mais de um código oral e tenta acioná-los de acordo com o contexto enunciativo. Isso aponta para duas conclusões: a geração mais nova, se não domina todas as regras da língua padrão, ao menos reconhece o ambiente em que sua variedade é aceita e conhece os mecanismos para adequar sua fala, mesmo que não consiga êxito em todas as suas realizações; e, se há problemas com a aceitabilidade dessa variedade é porque ela sofre preconceito. Assim, como provavelmente os mais velhos foram os que mais ficaram expostos a avaliação negativa de fala, eles reproduzem a estigmatização que sofreram, buscando concordância e complementaridade com seu interlocutor. Já os jovens utilizam, como estratégia contra o preconceito, sua capacidade de acomodação e convergência de fala.
Clinician assessment of acute coronary syndrome in the emergency department
Authors: Chapple Allyson M , Chuang Ming-Yu Anthony , Clark Robyn A , Horsfall Matthew , Blyth Andrew , Chew Derek , Astley Carolyn
Published: October 2018

Background:

Patients with chest pain represent a large portion of emergency department (ED) presentations around the world. Accurate risk assessment to rule out acute coronary syndrome (ACS) is required.

Aim:

To measure accuracy and characteristics of ED doctors and nurses when assessing patients for suspected ACS and the associations with outcome.

Methods:

A sub-analysis of a large randomised trial that compared high-sensitivity troponin to conventional troponin was carried out. Both nurses and doctors conducted ACS risk assessments on 1857 patients and concordance comparisons were undertaken.

Findings:

There was no difference between the accuracy of ED nurses and doctors (c-statistic: 0.67 vs 0.68 respectively; P=0.35). Both clinician types made similar ACS risk assessments. Nurses with specialist qualifications and consultant doctors were the most accurate, at 65.4% and 74.2%, respectively.

Conclusion:

Nurses and doctors in the ED made similar ACS risk assessments but both were sub-optimal. Standard clinical pathways to assist ED doctors and nurses improve their ACS impression accuracy could be beneficial.

PROPRIEDADES REOLÓGICAS DE AMIDOS DA FRUTA-DE-LOBO FOSFORILADOS COM TRIPOLIFOSFATO DE SÓDIO
Authors: Martins Luila Carla Victor , ASCHERI DIEGO PALMIRO RAMIREZ
Published: September 2018

Este artigo descreve a modificação química de um amido não convencional por meio da fosforilação, melhorando suas características para atender às demandas do mercado consumidor. Estudaram-se as propriedades reológicas de amido da fruta-de-lobo fosforilados com diferentes concentrações de tripolifosfato de sódio (5, 7 e 9%) e tempos de reação (20, 30 e 40 min). As leituras reológicas foram adquiridas em temperaturas que variaram de 80 a 98 °C. O modelo de Herschel-Bulkley foi ajustado aos dados experimentais de tensão de cisalhamento versus taxa de deformação das suspenções aquosas de amidos nativos e fosforilados. As amostras apresentaram comportamento pseudoplástico. Verificou-se que os amidos fosforilados são mais viscosos que o amido nativo. Em concentrações de 1,3-2% de amidos fosforilados se obtêm boas leituras reológicas no viscosímetro Brookfield. As suspenções aquosas formadas por 1,5% de amido fosforilado produzido nas condições de 5 e 9% de tripolifosfato de sódio por 30 min de reação, apresentam maiores valores de tensão de cisalhamento, em todas as taxas de deformação e temperaturas estudadas, alcançando um valor de viscosidade aparente de 275 cP.

O presente trabalho teve como objetivo estudar e avaliar a quantidade e qualidade das publicações científicas com Jatropha curcas abordando Biodiesel, Genética, Biotecnologia, Farmacologia, Pragas e Doenças. Para análise cienciométrica sobre Jatropha curcas foram obtidos dados no período entre 2015 e 2016 no laboratório de informática da Universidade Estadual de Goiás-Câmpus Ipameri/GO acessando a plataforma Thomson Reuters (ISI-Web of Science), avaliando-se os artigos com base na busca dos termos chave “Jatropha curcas” e “phisic nut’. O conjunto de artigos foi organizado conforme os temas: Biodiesel, Genética, Biotecnologia, Farmacologia, Pragas e Doenças, em seguida, catalogadas as seguintes informações: Tema, título, número de autores, país de desenvolvimento, nome do periódico e fator de impacto (Journal Citations Reports-JCR). As pesquisas com Jatropha curcas são voltadas principalmente para produção de biodiesel em função do elevado teor de óleo nas sementes desta espécie. A literatura é escassa de informações a respeito dos estresses bióticos (pragas e doenças) para a cultura do pinhão manso. Os países que mais publicam trabalhos científicos com Jatropha curcas nos temas de biodiesel, genética, biotecnologia, farmacologia, pragas e doenças são Índia, China, Brasil, Malásia e Tailândia. A maior parte dos trabalhos apresentam baixo fator de impacto (JCR) e disponibilizados principalmente em língua inglesa.

Published: September 2018

A seleção de cultivares adaptadas regionalmente pode favorecer o cultivo do pimentão por médios e pequenos agricultores no semiárido baiano. Assim, objetivou-se avaliar o desempenho de um híbrido e três cultivares de pimentão em condições de campo na região semiárida baiana. Foi utilizado o Híbrido TE 300 (Maestro) e três cultivares de pimentão (All Big, Quadrado vermelho e Ikeda), com quatro repetições, dispostos em delineamento experimental em blocos casualizados. Aos 90 dias após o transplante iniciou-se a colheita dos frutos, no qual, no final do ciclo totalizaram cinco colheitas. Em cada colheita foram avaliadas as variáveis: número de flores, folhas e ramos, altura de plantas, comprimento, diâmetro, número e peso dos frutos. A partir do peso dos frutos estimou-se a produtividade do híbrido e das cultivares obtidas em cada colheita e a produtividade final resultado do somatório das cinco colheitas realizadas. Verificou-se que o pimentão híbrido Maestro apresenta melhores características de crescimento e maior produtividade e a cultivar Quadrado Vermelho pode ser uma segunda alternativa de produção nas condições do presente estudo.

Published: September 2018

Este estudo teve como objetivo verificar a utilização das cascas e amêndoas do pequi por moradores de duas cidades do Norte de Minas Gerais, bem como os municípios que disponibilizaram sua venda ao Ceasa/Minas de Belo Horizonte no período de janeiro de 2016 a janeiro de 2017. O consumo do fruto foi avaliado após a compra do pequi no Mercado Municipal de cada cidade por meio de um questionário semiestruturado. Analisou-se os dados do Ceasa/Minas de 2016 e 2017 quanto ao fornecimento de pequi por 22 municípios mineiros. Participaram do estudo 53 indivíduos adultos das cidades de Montes Claros (MG) e Porteirinha (MG), que apresentaram um consumo mensal médio durante os meses da safra de 4,0±2,9 kg em Montes Claros (MG), e 5,8±4,5 kg em Porteirinha (MG). Os avaliados relataram não consumir as cascas do pequi por desconhecerem sobre a sua importância nutricional, e poucos ingeriam suas amêndoas. Os principais municípios mineiros fornecedores de pequi para o Ceasa/Minas foram Paraopeba, Santana de Pirapama e Curvelo. Conclui-se que a maioria dos avaliados não consumiam os resíduos deste fruto (casca e amêndoas), destacando a necessidade de mais divulgação sobre seus benefícios nutricionais, e 3 municípios foram os principais fornecedores deste fruto no período avaliado.
ESTUDO COMPARATIVO DE MANEJO FITOSSANITÁRIO / NUTRICIONAL: QUIMIGAÇÃO X APLICAÇÃO CONVENCIONAL, EM ÁREA IRRIGADA POR PIVÔ CENTRAL, COM SOJA, MILHO E TOMATE INDUSTRIAL

Published: September 2018

Uma maneira de reduzir os custos com irrigação é o uso da quimigação, visto que os custos com operações tratorizadas são minimizados. Porém, essa redução nos custos é específica para cada sistema agrícola. Assim, este trabalho se propôs a quantificar a redução destes custos e o consequente aumento na lucratividade, para uma área de 80 ha irrigada com pivô central, em cultivos sucessivos de soja, milho e tomate industrial no estado de Goiás. Os custos de produção foram calculados utilizando a planilha Amazonsaf para um projeto de 30 anos (Taxa Mínima de Atratividade - TMA de 12,0%). Nela foram inseridos os coeficientes técnicos de produção, obtidos na Federação da Agricultura do Estado de Goiás (FAEG), e calculados os indicadores financeiros: valor presente líquido (VPL), taxa interna de retorno (TIR), relação benefício custo (B/C) e payback. Os resultados mostraram que houve viabilidade econômica do empreendi- mento, independente da maneira que os fertilizantes e defensivos são aplicados. O VPL foi de R$ 1.670,94 ha-1.ano-1 e R$1.477,52 ha-1.ano-1, TIR de 31,94% e 27,98%, B/C de 1,31 e 1,27, e payback de 4 e 5 anos para quimigação e aplicação convencional, respectivamente. Observou-se que no sistema com quimigação houve redução no custo de produção, e a lucratividade aumentou na ordem de 2,68%.
SERAPILHEIRA ACUMULADA DE EUCALIPTO EM SISTEMA INTEGRADO DE LAVOURA-PECUÁRIA-FLORESTA
Authors: Silva Hilary Rodrigues da , Sousa Ferreira Jorge Luís , Calil Francine Neves
Published: September 2018

A importância da serapilheira se dá pelo retorno da matéria orgânica acumulada e nutrientes para o solo, representando grande parte da restauração da fertilidade deste, sendo essencial para a manutenção da capacidade produtiva da área. Em sistemas consorciados, como o ILPF, a decomposição da matéria orgânica é uma forma de sinergismo e complementaridade que beneficia a ciclagem de nutrientes possibilitando maior eficiência para meios de produção. O objetivo desse trabalho foi avaliar a produção de biomassa nas estações seca e chuvosa da serapilheira de um plantio de Eucalyptus urograndis em sistema integrado de lavoura-pecuária-floresta (ILPF) aos 5 (cinco) anos de idade. O estudo foi realizado no município de Cachoeira Dourada, em um sistema integrado de lavoura-pecuária-floresta, na Fazenda Boa Vereda, ao sul do Estado de Goiás, GO, Brasil. Para a coleta de serapilheira acumulada foram utilizados quatro renques com dois tratamentos – um entre plantas e um entre linhas de eucalipto. Foram coletadas 50 amostras aleatoriamente nos renques, sendo 25 amostras entre plantas e 25 entre linhas. Para a coleta da serapilheira acumulada utilizou-se um gabarito de madeira com área de 0,0625 m2). Após secagem do material em estufa de circulação e renovação de ar por 72 horas a 65°C, foi separado em cada componente (folha, galho/casca, miscelânea) e obtido seu peso total. Os valores obtidos no estudo realizado foram: 11,16 Mg ha-1 no período chuvoso e 12,66 Mg ha-1 no período seco, com um incremento de 1,49 Mg ha-1 (13,43%) na biomassa total acumulada. As maiores quantidades absolutas foram da porção galho/casca, porém o maior incremento foi da porção miscelânea seguido da porção folha. Houve maior porcentagem de deposição da fração folha e miscelânea entre plantas e da fração galho/casca e miscelânea entre linhas. O período seco apresentou a maior acúmulo de biomassa, principalmente pelo percentual de biomassa acumulada da fração folhas e galho/casca.

Published: September 2018

O cultivo in vitro tem sido empregado para a propagação e conservação de orquídeas. Neste contexto, estabeleceu-se um método eficiente de propagação in vitro para Coppensia ranifera (Lindl.) F. Barros & V. T. Rodrigues utilizando a técnica de camada fina celular longitudinal (lTCL). Foram utilizados protocormos germinados in vitro seccionados longitudinalmente (2 mm) em meio Knudson C líquido estacionário e semissólido, suplementado com thidiazuron (TDZ) (1,0 a 8,0 mM) para a formação de estruturas semelhantes a protocormos (ESP). Para a regeneração de plântulas foi utilizado meio de cultura isento de regulador de crescimento vegetal. A formação de ESP ocorre por via direta, sem calo. A utilização de meio de cultura líquido é mais eficiente do que o meio semissólido com relação ao número de ESP formado por explante. Em meio líquido de cultura o maior percentual de formação e o maior número de ESP por explante ocorre com a adição de 4 mM de TDZ. A eficiência (percentual de conversão) na regeneração de plântula em meio semissólido é maior do que em meio líquido.

Streptomyces sp. LCJ12A was isolated from the soil and sediments of Pichavaram Mangrove Forest, Tamil Nadu, India. Production of protease from the Streptomyces sp. LCJ12A was carried out by using submerged fermentation. To enhance the protease production, the fermentation medium was formulated and optimized. Different carbon, nitrogen and inducer sources were used for the optimization. In that fructose, sodium nitrate and red gram husk showed greater quantity of protease production and their different concentrations were optimized in Protease production broth (PPB). Response surface methodology (RSM) was employed for the medium optimization at a low cost for the production of industrially important enzyme. The optimized values showed that fructose at 2.0 g/L enhances the yield of protease up to 120.08±2.2 U/mL, sodium nitrate at 2.0 g/L maximize the protease production up to 180.35±1.9 U/mL and red gram husk at 2.0 g/L yields 194.16±2.2 U/mL which was 1.6 times higher when compared to the unoptimized medium. Statistical optimization by using RSM predicted that 327.16 U/mL of protease enzyme can be produced. Through experimentation based on RSM, the protease yield reached up to 323.4 U/mL. When compared to unoptimized medium, the statistically optimized medium produced 3 times higher yield. As a result of the optimization studies, an increase in protease activity was reached compared to the unoptimized conditions and thus offers a new approach for industrial enzyme production.
Gender Segregation Revealed: Five Years of Red Books Data Tell a Global Story
Authors: Deng Tao , Grow Jean M.
Published: September 2018

Abstract: This study explores five years of data from Red Books ( Standard Directory of Advertising Agencies ), a respected advertising industry database. Specifically, it explores the gendered composition of advertising creative departments across the globe, and is framed by sociological models of gender segregation and creative systems theory. The study demonstrates pervasive and systemic horizontal and vertical gender segregation within advertising creative departments worldwide. Using frequency test and correlation analysis, the authors analyzed 23,746 personnel data points from 4,713 agencies, in 50 countries, across five regions, from 2012 through 2016. In the process, they quantified the significant underrepresentation of women in advertising creative departments. The study demonstrates a global average of only 23.5% women working within advertising creative departments, while revealing an average of just 16.1% women within creative management. Detailed analysis by five geographic regions and by country is also presented. Finally, trend analyses predict a modest increase in women in advertising creative departments in 2017 and 2018, though not on a scale that would indicate systemic change.
Author Meets Critics: The Real Mad Men of Advertising
Authors: Hermann Molly , Franz Kathleen , Meyers Cynthia B. , Timke Edward
Published: September 2018

Abstract: This talk centers on The Real Mad Men of Advertising (2017), the Smithsonian Channel’s four-episode documentary series on the history of advertising after World War II through the 1980s. Advertising historians meet with the film’s producer to discuss how each episode takes up one decade after World War II and the prominent themes and issues in culture and society that advertising worked through at the time. Discussion topics include how and why the series was organized chronologically, the importance of using material objects in telling advertising history, what the series reveals about advertisers’ relationships with audiences over time, the series’ use of the Smithsonian Institution’s collections, the use of historical reenactments and footage, and possibilities for future documentaries on advertising.

Communication skill is the ability to transfer information to others. Students with Cerebral-Palsy have difficulty in pronouncing consonants when communicating with others. This difficulty is the effect of neural motoric disorder in the brain. It makes the information cannot be transferred well. This action research tries to improve the communication skills of students with cerebral palsy by using netbooks and smartphones as a tool to communicate. As a classroom action research, this study was conducted in four cycles. There is no significant improvement of the student communication skills in the first and second cycles. The third cycle shows that students’ communication skills were improved. It is particularly when the subject has utilised a notebook or a smartphone. In the fourth cycle, the student’s communication ability increases dramatically.[Keterampilan komunikasi adalah kemampuan untuk mentransfer informasi kepada orang lain. Siswa dengan Cerebral Palsy mengalami kesulitan dalam mengucapkan konsonan (non-vokal) ketika berkomunikasi dengan orang lain. Kesulitan ini adalah efek dari gangguan saraf saraf di otak. Hal ini membuat informasi tidak dapat ditransfer dengan baik, karena kerusakan otak berdampak pada organ-organ bicara. Teknologi membuat segalanya lebih mudah dan penelitian ini mencoba meningkatkan keterampilan komunikasi siswa dengan cerebral palsy dengan menggunakan notebook sebagai alat untuk berkomunikasi. Penelitian ini dilakukan dalam empat siklus melalui desain Penelitian Tindakan Kelas. Tidak ada peningkatan keterampilan komunikasi siswa yang signifikan pada siklus pertama dan kedua. Siklus ketiga menunjukkan bahwa keterampilan komunikasi siswa meningkat ketika subjek sudah menggunakan notebook sebagai alat untuk berkomunikasi.

Overview of current mouse models of autism and strategies for their development using CRISPR/Cas9 technology
Authors: DOMADENIK Anja
Published: September 2018

Autism spectrum disorders (ASD) are a group of highly heterogenous neurological disorders that are believed to have strong genetic component. Due to the limited use of approaches of functional genomics in human medicine, creating adequate animal models for the study of complex human diseases shows great potential. There are several already established mouse models of autism that offer insight into single phenotypic traits, although causes for its complex phenotype have not yet been fully understood. Development of new technologies, such as CRISPR/Cas9, represent great capability for targeted genome engineering and establishment of new animal models. This article provides an up to date overview of current knowledge in the area of autism genomics and describes the potential of CRISPR/Cas9 technology for the establishment of new mouse models, representing sgRNA design as one of the initial steps in planning a CRISPR/Cas9 single knock-out experiment. In addition, it offers an overview of current approaches to behavioural studies, explaining how relevant animal models could be developed.
Praca osób z głębszą niepełnosprawnością intelektualną jako źródło emancypacji w kontekście samorealizacji
Authors: Ramik-Mażewska Irena
Published: October 2018

The problem of normalization, autonomy and self-determination of people with intellectual disabilities in special education has already taken its place. The consequence of this continuing discourse is the personal nature of disability, international, timeless declarations and modifications of already established rights. Recently, the emancipatory trend is gaining in importance in this discourse. It remains in close correlation with the primary objective of educating people with intellectual disabilities which is comprehensive preparation for life. It is a form of conscious self-reliance, self-knowledge and capacity to take autonomous action. One of the areas of development of self-reliance is work. The resulting interpersonal and intrapersonal experiences can become the path to emancipation. Sometimes, one that goes beyond the standards of rehabilitation.

Published: October 2018

The purpose of this study was to gather data from the mothers of children with Tourette Syndrome (TS), in order to examine the extent to which the existence of a child with TS in the family affected mothers’ Quality of Life (QOL). The research was conducted according to the qualitative methods. Data was collected from semistructures interviews with 50 mothers of children with TS. The interviews were analyzed using a content analysis method. Conclusions derived from the research findings found that lack of accurate diagnosis and information leaded mothers to a state of imbalance and great stress. When they were given accurate information, they seemed to be more able to advocate for the child with TS and thus preventmisunderstandings, and consequent unpleasant situations and confusion.

The James Webb Space Telescope (JWST) is frequently referred to as the follow-on mission to the Hubble Space Telescope (HST). The ‘Webb’ will be the biggest space telescope ever built and is expected to enable astounding new science. The observatory comprises a 6.5-m-diameter telescope with a segmented primary mirror and four high-performance optical science instruments. The JWST has mostly been optimized to work in the near- (0.6–5.0 μm) and mid-infrared (5.0–29 μm) wavelength regions. The project is a strong international partnership led by the National Aeronautics and Space Administration (NASA) with contributions from the European Space Agency (ESA) and the Canadian Space Agency (CSA). The observatory is currently scheduled for launch in early 2021 from Kourou, French Guyana, by an ESA-provided Ariane 5 rocket. This paper will focus on the European optical contribution to the mission, which mainly consists of two highly advanced optical science instruments: The multi-object near-infrared spectrograph (NIRSpec) and the mid-infrared instrument (MIRI). The opto-mechanical design considerations and the realization of both instruments will be described, and we will conclude with a short JWST project status report and future outlook.
