Rap enquanto performance: um evento de comunicação e expressão musical
Authors: Cirino Andréa Cristina
Published: October 2017

Este texto pretende mostrar o rap como uma performance que transmite o discurso de uma periferia que clama por liberdade e justiça social por meio da linguagem artística. Elementos expressivos são observados em três exemplos que fazem parte do rap nacional, influenciado pela cultura hip hop. Com base nos pressupostos teóricos de Dayrell, Schechner, Zumthor e Carlson, a literatura revisada vem ao encontro de reflexões que apontam a importância desse estilo musical que implica práticas e representações no contexto histórico-cultural. Sob a perspectiva do fazer musical, podemos verificar a relação entre linguagem, gestualidade e arte. Conclui-se que o rap consiste não mais numa realidade local, tendo conquistado seu espaço mundialmente.
VITAE: recuperação de objetos de aprendizagem baseada na web 2.0
Authors: Coelho Geovália Oliveira , Ishitani Lucila , Nelson Maria Augusta Vieira
Published: October 2017

Objetos de aprendizagem (OA) são materiais digitais utilizados para apoiar o ensino e a aprendizagem. Tradicionalmente, OAs são desenvolvidos como material de apoio a professores. Entretanto, eles podem ser utilizados por alunos ou qualquer pessoa interessada em aprender um determinado assunto. OAs podem ser encontrados em repositórios ou na Web, em sites de docentes e de instituições de ensino. Apesar disso, nem sempre os OAs são facilmente encontrados. Em geral, os repositórios abordam poucos campos do conhecimento e poucas opções de línguas. As máquinas de busca retornam um grande volume de informação, o que dificulta, para o usuário, identificar os OAs que são relevantes para as suas necessidades. Nesse contexto, este artigo propõe um mecanismo para recuperação de OAs, baseado nos princípios da Web 2.0. Dentre as opções de aplicações Web 2.0, o modelo de bookmarking social se destaca por facilitar o armazenamento de links a OAs e por permitir o compartilhamento e a classificação desses links. Além disso, ao contrário do que ocorre com os repositórios, essas ferramentas permitem que qualquer usuário possa postar novos links, sem restrições. O protótipo dessa ferramenta foi denominado VITAE. VITAE oferece o serviço de bookmarking social, de forma que usuários possam armazenar, organizar, avaliar e compartilhar links com outras pessoas.

Filmes e negritude em sala de aula: essa relação é possível?
Authors: Teruya Teresa Kazuko , Felipe Delton Aparecido
Published: October 2017

As Diretrizes e Bases da Educação Nacional estabelecem o cumprimento Lei 10.639/2003 para educação étnico-racial. Para problematizar a educação da negritude no Brasil este artigo discute a seguinte questão: Quais são as potencialidades das narrativas fílmicas na sala de aula para o ensino da história e cultura afrobrasileira e africana? Para isso apresentamos dados coletados junto a um grupo de docentes que freqüentaram o curso de extensão realizado no decorrer de 2008 intitulado: O cinema no ensino de história e cultura afro-brasileira e africana na educação básica. Os resultados indicam a existência do potencial pedagógico da filmografia, mesmo que os/as docentes não saibam explorar as narrativas fílmicas que ajudem seus alunos/alunas a visualizarem o “outro”. Concluímos que a utilização de filmes como fonte de estudo ou como ferramenta pedagógica, exige uma ação pedagógica critica de decodificação, interpretação e desconstrução das narrativas fílmicas para perceber o registro das ações humanas representadas na tela.
Entre nós, em defesa de uma escola
Authors: Kohan Walter Omar
Published: October 2017

Neste texto, proponho-me a esclarecer alguns aspectos da defesa da escola realizada por J. Masschelein e M. Simons em sua obra Em defesa da escola, bem como incorporar alguns elementos próprios de uma outra tradição – a escola popular de Simón Rodríguez – com o intuito mais amplo de aprofundar o debate desencadeado pelas teses dos autores belgas e torná-las ainda mais ressoantes para o contexto brasileiro. Para isso, na “Apresentação”, situo a importância do debate no atual cenário da educação nacional. Na seção seguinte, “Em defesa da escola”, apresento as teses principais do livro, assim como o caráter específico da proposta dos autores belgas sobre as relações entre escola e política. Já na seção “Em defesa da defesa: uma visão (a)política?”, contextualizo os principais autores que influenciaram a obra e detalho a maneira específica como ela se situaria em oposição a propostas como “Escola sem Partido”, as quais sintetizam a atual política educativa do governo brasileiro. Em “A invenção de uma escola entre nós”, introduzo alguns elementos da proposta de escola popular de Simón Rodríguez e, em particular, sua aposta na invenção e na atenção. Por último, em “Considerações Finais” incorporo a ideia de errância na afirmação de uma escola outra entre nós, inspirado em Le Tiers-Instruit de M. Serres.

Background: Lipid profiles are altered by HIV infection and antiretroviral therapy (ART). Among HIV-uninfected (HIV-) populations the concentrations of various lipid classes (ie, lysophosphatidylcholine, LPC) and their saturated (SaFA), monounsaturated (MUFA), and polyunsaturated fatty acid (PUFA) composition are related to cardiometabolic disease risk. Associations between changes in the lipidome and immune activation in HIV-infected (HIV+) individuals beginning ART have not been described. Methods: Plasma lipid concentrations and their fatty acid composition were measured by differential mobility spectroscopy in samples from 35 treatment-naive HIV+ participants beginning raltegravir (RAL)-based ART and from HIV- individuals (N=13) matched for age and sex. Results: The levels of SaFA, including palmitic (16:0) and stearic (18:0) acid were enriched in HIV+ participants (pre- and post-ART), and SaFA levels were often positively correlated with levels of immune activation (ie, IL-6, sCD14, and TNFR1) at baseline and week 48. Levels of PUFAs (including 18:3, 20:4, and 20:5) were lower in HIV+ participants at baseline compared to levels in HIV- participants (P<0.01), and levels of these PUFAs were increased following 48 weeks of ART. Levels of PUFAs were often inversely related to immune activation. Levels of LPC were increased in HIV+ participants, both pre- and post-ART vs HIV- participants, and the composition of LPC was enriched for SaFAs among HIV+ individuals. At week 48, several LPC molecules containing SaFAs were positively correlated with levels of sCD14, D-dimer, and TNFR1 (P<0.01), and levels of PUFA-containing LPC (18:3, 20:5, 22:5, 22:6) were positively correlated with CD4+ T cell counts and inversely correlated with sCD14 and IL-6 (P<0.01). Conclusions: The composition of the lipidome is altered in HIV infection and changes when ART is administered. Alterations in SaFAs were generally associated with inflammatory markers and may contribute to comorbid disease pathogenesis.
Una nota sobre la devaluación contractiva bajo un esquema de metas de inflación
Authors: Libman Emiliano
Published: October 2017

Antecedentes: Una de las contribuciones más sobresalientes de la teoría estructuralista es la hipótesis de la devaluación contractiva. La misma fue desarrollada en un contexto de tipos de cambios fijos o semifijos y poca movilidad de capitales. Aunque la literatura ha incorporado nuevos problemas como los efectos “hoja de balance”, aún no se han examinado los problemas que la hipótesis plantea para la administración de un régimen de metas de inflación.Métodos: Analizamos las condiciones de estabilidad de un modelo estilizado, cuyas ecuaciones describen economías como las de América Latina, combinando los efectos contractivos de la devaluación con reglas de política monetaria.Resultados: En presencia de efectos contractivos de la devaluación existen efectos desestabilizadores asociados a los movimientos del tipo de cambio. La estabilidad es más probable si el Banco Central renuncia a estabilizar el producto. Las políticas de acumulación de reservas incrementan la probabilidad de obtener un sistema estable.Conclusiones: El carácter contractivo de la devaluación dificulta el manejo de la política monetaria bajo un esquema de metas de inflación. Las políticas que regulan los flujos de capitales, junto con la intervención cambiaria, pueden jugar un papel relevante en la administración exitosa de dicho régimen.
Therapeutic Breathing Techniques and Disparity across Student Performance in English and Mathematics
Authors: Gupta Abha , Pribesh Shana , Diawara Norou
Published: October 2017

This paper explores possible correlation between Therapeutic Breathing Techniques (TBT) and improved academic performance of low achieving students in elementary school. The intervention consisted of daily breathing exercises combining two forms of TBT, namely, deep breathing and alternate nostril breathing.  A semester-long quantitative study with85 second graders was conducted to investigate the impact of above intervention on English and mathematics scores. Following one semester of intervention, the gaps between the low and high achievers had narrowed and small but significant gain-scores were found for the low achievers who had practiced TBT.  In contrast, in first and third grades, where neither low achievers nor high achievers received the treatment, the gap between the low and high achievers widened slightly. The findings indicate the need to further investigate the potential merit of therapeutic breathing exercises as a low-cost intervention strategy for improving school performance and addressing achievement gaps, especially in mathematics.

Corporate Governance Practices of Family Enterprises: A Study on Some Selected Indian Family Governed Companies
Authors: Majumder Amit
Published: October 2017

Corporate governance implies how an organization is directed and controlled under a set of mission, values, and philosophy (Cadbury, 1992). But unfortunately, over time, the common investors all over the globe have suffered a lot in the hands of the greedy managers and scams like Enron, Adelphia, Tyco, Worldcom, Xerox, Paramalt, and Satyam have shattered the trust in the very mechanism of corporate management and governance. However, despite a lot of initiatives had been taken around the world in the form of codes/laws for ensuring good governance for corporate sector, the issue of governance practices of family enterprises operating in India had not been discussed in detail. But, in view of the contribution of the family enterprises to Indian Economy over the years, a renewed interest on their governance mechanism is the need of the hour. Starting from Tata to Birla, Ambani, Goenka, Ruia, Mittal etc. Corporate India had a long heritage of domination of family governed firms. They contribute significantly towards economic growth of the country, employment generation, boosting up Gross Domestic Production as well as accumulation of foreign reserve through growth in export and also engaged into cross border Merger and Amalgamations. However, time and again the issues of governance and succession policy had perturbed the smooth sailings of these family governed firms in India. Recent examples like clash between Ambani brothers, inheritance issues in Birla clan proved that case. Against this backdrop the present study is a humble attempt to enquire the state of affairs of corporate governance in major family governed firms in India.

Authors: Arora J. K. , Agarwal Siddharth
Published: October 2017

To improve the quality of life, there has been the search of strategies for handling stress, and subjective well-being. These explorations have led us to ancient disciplines such as Yoga, which combine the physical elements of a healthy lifestyle with mental peace. It integrates the personality by bringing body-mind-soul coordination in a well-balanced way. The present paper is aimed to create awareness of the need of regular practice of Yoga and Meditation among the matured group of students at university level which will certainly help to improve the qualities of their mind for not only worldly achievements and success in life but also in attains, the ultimate goal of life which is spiritual upliftment.  This scientific study compared ’impact of yoga alone and yoga with meditation on alteration of psychological profile of university level students. It was predicted that practitioners’ psychological wellbeing would vary as a function of their parameters like stress, ESP, PSI-Q, and Working Memory. Result was statically analyzed using null Hypothesis. The experimental results are very optimistic in that yoga & meditation combined practice can alter an individual’s social, self, physical and emotional  wellbeing .It also indicates  that practitioners with yoga with spiritual intentions reported significantly higher psychological wellbeing compared with practitioners doing  yoga alone.
Automated calibration of a two-dimensional overland flow model by estimating Manning's roughness coefficient using genetic algorithm
Authors: Drisya J. , Sathish Kumar D.
Published: October 2017

Calibration is an important phase in the hydrological modelling process. In this study, an automated calibration framework is developed for estimating Manning's roughness coefficient. The calibration process is formulated as an optimization problem and solved using a genetic algorithm (GA). A heuristic search procedure using GA is developed by including runoff simulation process and evaluating the fitness function by comparing the experimental results. The model is calibrated and validated using datasets of Watershed Experimentation System. A loosely coupled architecture is followed with an interface program to enable automatic data transfer between overland flow model and GA. Single objective GA optimization with minimizing percentage bias, root mean square error and maximizing Nash–Sutcliffe efficiency is integrated with the model scheme. Trade-offs are observed between the different objectives and no single set of the parameter is able to optimize all objectives simultaneously. Hence, multi-objective GA using pooled and balanced aggregated function statistic are used along with the model. The results indicate that the solutions on the Pareto-front are equally good with respect to one objective, but may not be suitable regarding other objectives. The present technique can be applied to calibrate the hydrological model parameters.
Measuring climate change adaptation in Pacific small island states: nissology and success
Authors: B. Schwebel Michael
Published: October 2017

Pacific small island states (PSIS) currently experience harsh impacts of a changing climate: sea level rise, saltwater intrusion, internal migration and displacement. Are adaptation strategies based upon island-centric principles more successful than those originating from a more continental point of view? This research examined the principles of island-centric thinking using an island-centric lens by which to determine ‘successful’ climate adaptation planning. The findings illustrate a statistically significant relationship between PSIS that have higher nissological (island-centric) levels displayed within their climate change action plans (CCAPs) and CCAPs that were found to be more successful. In other words, highly nissological states are forecasted to be more successful in planning for the current and future impacts of climate change than those with lower nissological scores. In total, nissology explains approximately 28.37% of a PSIS's success. The policy relevance is rooted in the unique cultural, geographical, and social aspects of islands. Findings are applicable to other islands as well countries that share islander-based qualities. The methodological and quantitative-based areas of the study assist in forming policy-relevant determinations for island societies based on the climate-related parameters and metrics tested and evaluated herein.
Comparison of annual maximum rainfall events of modern rain gauge data (1961–2010) and Chukwooki data (1777–1910) in Seoul, Korea
Authors: Yoo Chulsang , Park Minkyu , Kim Hyeon Jun , Jun Changhyun
Published: October 2017

In this study, the annual maximum rainfall event series were constructed and compared for both the modern flip-bucket type rainfall data, collected since 1961 (the modern data), and the old Chukwooki rainfall data, collected from 1777 to 1910 (the Chukwooki data). First, independent rainfall events were derived, by applying the same rainfall threshold of 2 mm and data collection time interval of 2 hours, to both the Chukwooki and the modern data. Annual maximum rainfall event series were then constructed, by applying Freund's bivariate exponential distribution annually. Finally, bivariate frequency analysis was done for the annual maximum rainfall event series constructed, by applying the bivariate logistic model to evaluate and quantify their characteristics. The results are in summary: (1) characteristics of the Chukwooki rainfall events and modern rainfall events are very similar to each other; (2) the annual maximum rainfall events of modern data are slightly larger than those of the Chukwooki data. The total rainfall depth per rainfall event for any given return period is thus estimated to be a little higher for the modern data than that of the Chukwooki data. However, based on the findings in this study, it could not be concluded that the rainfall characteristics have significantly changed during the last 200 years.
Examining adaptation using the Message Actor Channel (MAC) model of communicative water practices
Authors: Ajia F. O.
Published: October 2017

Water utilities rely on technological interventions to achieve household water efficiency. This practice is critiqued as seeking to appeal to the financial interests implied by people's role as customers rather than to achieve behavioural change in householders. A policy analysis reveals that although not prominently evidenced by some water utilities, public engagement is key to long-term demand reduction. This paper presents a systematic review of the demand management literature, specifically outlining key theoretical considerations for public engagement in relation to reducing water demand and their translation into practice in utilities. The aim is to demonstrate the use of a framework for examining engagement in utilities. Findings show that demand management interventions need to exploit: (1) effective frames for messages, (2) the diversity of the public, and (3) communication mediums that facilitate feedback. These insights informed the development of the MAC (Message Actor Channel) model of communicative water practices further used in this study to review public engagement plans for household water efficiency in selected UK water utilities based on processes described in their 2014 water resources management plans. Findings will inform the next stages of a doctoral study that will assess utilities' field engagement of households to reduce water use.

HBV-Infection and Pregnancy
Authors: Matejko H. , Matvisiv M.
Published: October 2017

To date, the problem of HBV-infection in pregnant women remains relevant and one of the most important for medical science and health care, as it can be considered as a maternal-fetal infection.The aim of the research is to investigate the course of HBV-infection in pregnant women, depending on the duration of the disease, the degree of viremia and the activity of hepatitis, taking into account gestational periods.Materials and methods. The course of pregnancy in 142 women aged 18-35 years with HBV-infection was monitored. Serum markers and viral load (VL) of hepatitis B (HB) were determined, as well as the levels of ALT, AST, thymol test, serum bilirubin levels during each trimester of pregnancy.Results. In pregnant women with HBV-infection, HBsAg-carriage was most often diagnosed, and the replication stages were less frequent (96 and 46, respectively).Clinical picture of the immune-active phase of chronic HBV-infection was oligosymptomatic without violation of pigment metabolism and manifestations of mesenchymal-inflammatory reaction. The minimal degree of cytolysis prevailed, which did not depend on the degree of the viremia. In women with immune-tolerant phase of cytolysis during pregnancy was not observed.In pregnant women with replication stage of HBV-infection and low degree of viremia, the VL increased at 1-2 log compared to the second and third trimesters, and in women with high viremia – at 2-3 log.In most women-carriers of HBsAg moderate degree of viremia predominated, and in the rest – it was not determined. During the entire pregnancy, the immune-tolerant phase of chronic HBV-infection was latent and did not transform into the immune-active phase.Conclusion. Thus, the diagnosis of chronic HBV-infection was verified before pregnancy in 2.8 %, and during pregnancy – in 97.2 % of women. Carriage of HBsAg prevailed in them (67.6 %), and replicative forms were registered in 32.4 % of patients. The peculiarity of replicative forms is subclinical (65.3 %) and asymptomatic (34.7 %) clinical course with low VL (˂ 105 copies/mL), which in most cases (91.3 %) increases before delivery at 1-2 log and is accompanied by low activity of hepatitis, without violation of pigment metabolism.

Background: Osteodensitometry, a procedure increasingly accepted by clinicians to access osteoporosis is not yet fully validated by WHO. It requires the establishment of normal values and references curves for each population, and in our community, this is not yet assessed.

The purpose of this study was twofold: to describe the profile of the speed of sound of proximal phalangeal metaphysis and establish references curves in central Africans and to compare them with those of other populations specially Caucasians.

Methods: This cross sectional study was carried out at Kinshasa, Democratic Republic of the Congo in Central Africa from January to December 2016.

Four hundred twenty four subjects aged from 20 to 87 years old, were explored and the speed of sound in theirs proximal phalanges measured using ultrasound equipment. Age, gender, hormonal status and speed of sound were collected and analyzed.

Results: The mean value of the amplitude dependant speed of sound (AD-SoS) showed a growth feature with age (from 2056 m/sec at second decade of life to 2145.27 m/sec at fourth decade followed by a progressive decrease which was present in both sexes but more marked in postmenopausal women (1927.06 m/sec). This mean value was higher than in Caucasian studies. In this study, age and hormonal status seems to be the bone quality most influencing anthropometric factors as seen in many series.

The curve profile with age was also a polynomial curve as seen in others populations of the world.

Conclusion: This study provides normal data for phalangeal ultrasound measurements and reference curve of central Africans which were compared to those of Western studies.
Stress-Strain State of Non-Involute Tooth of the Planetary Gearwheel

Published: October 2017

Многосателлитные планетарные передачи широко распространены в приводной технике благодаря высокой нагрузочной способности и хорошим массогабаритным характеристикам. Конструкции таких передач предусматривают наличие солнечной шестерни и центрального колеса с внутренними зубьями и толщиной обода не ниже трех модулей, установленного неподвижно в корпусе планетарного механизма. В созданных в ИжГТУ имени М. Т. Калашникова передачах неподвижное центральное колесо выполнено в виде барабана с неэвольвентными зубьями-перемычками, что позволяет уменьшить радиальный размер передачи на толщину обода колеса. Кроме того, повышенная податливость зубьев-перемычек положительно сказывается на распределении нагрузки в зацеплениях колес. Однако они имеют более низкую изгибную прочность, нежели стандартные эвольвентные зубья, так как радиус кривизны переходной кривой неэвольвентного профиля оказывается близким к нулю. Для определения напряжения изгиба зуба-перемычки в месте его заделки в обод колеса элемент обода представлен в виде балки на упругом основании, для которого составлено уравнение связи силовых факторов и деформаций изгиба и сдвига. Полученное дифференциальное уравнение напряженно-деформированного состояния решалось аналитическим методом Эйлера. Из выполненных расчетов следует, что напряжения в основании зуба-перемычки существенно больше напряжений в основании эвольвентного зуба. В связи с этим колеса с неэвольвентными зубьями-перемычками целесообразно использовать в сравнительно малонагруженных планетарных передачах, рассчитанных на длительный срок службы, несущая способность которых лимитируется контактной прочностью зубьев колес.

Рассмотрен анализ пяти конкурентных сил Майкла Портера для строительной организации с точки зрения применения систем автоматизированного проектирования (САПР). В настоящее время созданы программные комплексы, обеспечивающие автоматизацию рутинных процедур и операций, таких как подготовка текстовой документации, преобразование технических чертежей, построение графических изображений и т. д. Для определения уровня конкуренции применена методика анализа отрасли и выработки стратегии предпринимательства, разработанная Майклом Портером в Гарвардской школе бизнеса в 1979 г. Анализ проводится для идентификации благоприятных возможностей и опасностей, с которыми может столкнуться компания в отрасли. М. Портер предложил «модель пяти сил», которая аргументирована тем, что чем выше давление со стороны выделенных факторов, тем меньше у компании возможности увеличивать прибыль. Компания, изменив свою стратегию, может воздействовать на эти силы в свою пользу. Конкурентные силы сгруппированы в пять направлений: 1) рыночная власть поставщиков; 2) рыночная власть покупателей (заказчиков); 3) появление продуктов-заменителей; 4) выход на рынок новых участников-предприятий; 5) конкурентная борьба. Описаны силы и как они влияют на строительные организации. Анализ представлен в табличной форме.

The Economic Rise of China: Its Threats and Opportunities from the Perspective of Southeast Asia
Authors: Ng Beoy Kui
Published: October 2017

Abstract

The purpose of the paper is to examine the economic impact of China on Southeast Asian countries, mainly in terms of trade and investment. The paper attempts to examine whether the rise of China poses a threat to Southeast Asia as a region in the area of international trade, especially competition in third country markets, and asks, can they be friends and allies rather than competitors in international market? Secondly, the paper also questions if the concentration of foreign direct investment (FDI) in China is resulting in a diversion of FDI away from the region. Do FDI in China and Southeast Asia complement one another when it comes to the international division of labour? On the other hand, the increasing role of China as an international trader and global investor provides an opportunity for Southeast Asia countries to integrate with the Chinese economy. The huge domestic market of China also provides vast opportunities for investment, especially through connections with their respective ethnic Chinese businesses in the region. The overall assessment is that the rise of China will benefit Southeast Asian countries, especially in terms of China's role in the Asian production network, destination for investment, its outward investment and more importantly, its huge and growing domestic market. All these turn China into another driver for economic growth in Asia.

Keywords: China, FDI flows, Southeast Asia, trade, investment, Asia production networks.

Phase equilibria in the ternary Ag-Au-Ga system: Isothermal sections at 250°C and 450°C
Authors: Jendrzejczyk-Handzlik D.
Published: October 2017

The ternary Ag-Au-Ga system seems to be interesting in jeweller?s craft as a joint. Moreover, the ternary systems based on gold and silver have found applications in the dental industry. A literature overview of the Ag-Au-Ga system shows that the information about phase equilibria of this system does not exist. In the present work, phase equilibria in the Ag-Au-Ga ternary system have been studied by using scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) analysis and X-ray diffraction analysis (XRD). Twenty two annealed alloys in the 10-70 at.% Ga region have been investigated. Obtained experimental results were compared with the predicted isothermal sections at two temperatures (250?C and 450?C). No ternary compounds are found.

Objective:

The purpose of this study was to compare the treatment effects of palatally vs buccally placed temporary anchorage devices.

Materials and Methods:

Of 40 Class II division 1 malocclusion patients, 22 were treated with modified C-palatal plate (MCPP) appliances (age 21.9 ± 6.6 years), and 18 (age 24.2 ± 6.8 years) were treated with buccally placed miniscrews between the maxillary first molar and second premolar. A total of 26 linear and angular measurements were analyzed on pre- and posttreatment lateral cephalograms. Multivariate analysis of variance was performed to evaluate the treatment effects within each group and to compare the effects between groups.

Results:

Overall, the MCPP appliances showed 4.2 mm of distalization, 1.6 mm of intrusion of the first molar with 2° tipping, and 0.8 mm extrusion of incisors. The miniscrew group resulted in 2.0 mm of distalization, 0.1 mm intrusion of the first molar with 7.2° tipping, and 0.3 mm of incisor extrusion. Regarding soft tissue change, in the MCPP group, the upper lip was significantly retracted (P < .001).

Conclusions:

Comparing the treatment effects between MCPP appliances and buccal miniscrews, the MCPP appliances showed greater distalization and intrusion with less distal tipping of the first molar and more extrusion of the incisor compared to the buccal miniscrews.

Inhibition of notch signaling is known to induce differentiation of endocrine cells in zebrafish and mouse. After performing an unbiased in vivo screen of ∼2,200 small molecules in zebrafish, we identified an inhibitor of Cdk5 (roscovitine), which potentiated the formation of β-cells along the intrapancreatic duct during concurrent inhibition of notch signaling. We confirmed and characterized the effect with a more selective Cdk5 inhibitor, (R)-DRF053, which specifically increased the number of duct-derived β-cells without affecting their proliferation. By duct-specific overexpression of the endogenous Cdk5 inhibitors Cdk5rap1 or Cdkal1 (which previously have been linked to diabetes in genome-wide association studies), as well as deleting cdk5, we validated the role of chemical Cdk5 inhibition in β-cell differentiation by genetic means. Moreover, the cdk5 mutant zebrafish displayed an increased number of β-cells independently of inhibition of notch signaling, in both the basal state and during β-cell regeneration. Importantly, the effect of Cdk5 inhibition to promote β-cell formation was conserved in mouse embryonic pancreatic explants, adult mice with pancreatic ductal ligation injury, and human induced pluripotent stem (iPS) cells. Thus, we have revealed a previously unknown role of Cdk5 as an endogenous suppressor of β-cell differentiation and thereby further highlighted its importance in diabetes.

Studies using self-reported data suggest a gene–physical activity interaction on obesity, yet the influence of sedentary behavior, distinct from a lack of physical activity, on genetic associations with obesity remains unclear. We analyzed interactions of accelerometer-measured moderate to vigorous physical activity (MVPA) and time spent sedentary with genetic variants on obesity among 9,645 U.S. Hispanics/Latinos. An overall genetic risk score (GRS), a central nervous system (CNS)–related GRS, and a non-CNS-related GRS were calculated based on 97 BMI-associated single nucleotide polymorphisms (SNPs). Genetic association with BMI was stronger in individuals with lower MVPA (first tertile) versus higher MVPA (third tertile) (β = 0.78 kg/m2 [SE, 0.10 kg/m2] vs. 0.39 kg/m2 [0.09 kg/m2] per SD increment of GRS; Pinteraction = 0.005), and in those with more time spent sedentary (third tertile) versus less time spent sedentary (first tertile) (β = 0.73 kg/m2 [SE, 0.10 kg/m2] vs. 0.44 kg/m2 [0.09 kg/m2]; Pinteraction = 0.006). Similar significant interaction patterns were observed for obesity risk, body fat mass, fat percentage, fat mass index, and waist circumference, but not for fat-free mass. The CNS-related GRS, but not the non-CNS-related GRS, showed significant interactions with MVPA and sedentary behavior, with effects on BMI and other adiposity traits. Our data suggest that both increasing physical activity and reducing sedentary behavior may attenuate genetic associations with obesity, although the independence of these interaction effects needs to be investigated further.

OBJECTIVE

Grip strength and diabetes are predictors of mortality and cardiovascular disease (CVD), but whether these risk factors interact to predispose to adverse health outcomes is unknown. This study determined the interactions between diabetes and grip strength and their association with health outcomes.

RESEARCH DESIGN AND METHODS

We undertook a prospective, general population cohort study by using UK Biobank. Cox proportional hazards models were used to explore the associations between both grip strength and diabetes and the outcomes of all-cause mortality and CVD incidence/mortality as well as to test for interactions between diabetes and grip strength.

RESULTS

A total of 347,130 UK Biobank participants with full data available (mean age 55.9 years, BMI 27.2 kg/m2, 54.2% women) were included in the analysis, of which 13,373 (4.0%) had diabetes. Over a median follow-up of 4.9 years (range 3.3–7.8 years), 6,209 died (594 as a result of CVD), and 4,301 developed CVD. Participants with diabetes were at higher risk of all-cause and CVD mortality and CVD incidence. Significant interactions (P < 0.05) existed whereby the risk of CVD mortality was higher in participants with diabetes with low (hazard ratio [HR] 4.05 [95% CI 2.72, 5.80]) versus high (HR 1.46 [0.87, 2.46]) grip strength. Similar results were observed for all-cause mortality and CVD incidence.

CONCLUSIONS

Risk of adverse health outcomes among people with diabetes is lower in those with high grip strength. Low grip strength may be useful to identify a higher-risk subgroup of patients with diabetes. Intervention studies are required to determine whether resistance exercise can reduce risk.
