Quercetin feeding protects plants against oxidative stress
Authors: Kurepa Jasmina , Shull Timothy E. , Smalle Jan A. 
Published: October 2016

Background: Flavonoids are a complex group of plant-made phenolic compounds that are considered of high nutraceutical value. Their beneficial impacts on human health relate predominantly to their capacity to serve as antioxidants, thus protecting cells against the damaging impact of reactive oxygen species. Recent studies have also pointed at an essential role for flavonoids as antioxidants in plants. Results: Here we show that the flavonoid quercetin, which is known to protect human cells from oxidative stress, has the same effect on plant cells. Under oxidative stress conditions, Arabidopsis plants grown on quercetin-supplemented media grew better than controls and contained less oxidized proteins. This protection was also observed in the dicot Nicotiana tabacum and the aquatic monocot Lemna gibba. Conclusion: Quercetin can be used as a general antioxidant stress protectant for plants.

Published: October 2016

Ikan madidihang atau tuna sirip kuning (Thunnus albacares) merupakan salah satu komoditas penting bagi industri perikanan di Indonesia dengan hasil tangkapan tertinggi dibandingkan jenis tuna lainnya. Sebagai dasar pengelolaan sumberdaya ikan yang berkelanjutan, diperlukan data dan informasi tentang komposisi ukuran layak tangkap yaitu membandingkan proporsi rata-rata ikan tertangkap (Lc) dan matang gonad (Lm), serta nisbah kelamin sebagai indikator pendugaan kemampuan memijah. Pengumpulan data dilakukanmelalui program observasi diatas kapal rawai tuna yang berbasis di Benoa, Pelabuhanratu dan Bungus dari bulan Agustus 2005 hingga November 2013. Penghitungan nisbah kelamin menggunakan uji Chi-Square (X2) dengan tingkat kepercayaan 95%. Hasil penelitian menunjukkan bahwa distribusi ukuran panjang cagak ikan madidihang berkisar antara 30-179 cm, modus ukuran 106-110 cm dan rata-rata 101,65 cm. Sebanyak 81,03% madidihang yang tertangkap berukuran lebih besar daripada Lm yang berarti telah layak tangkap. Nisbah kelamin betina:jantan adalah 1:1,45 mengindikasikan dominansi ikan jantan. Hubungan antara nisbah kelamin dengan panjang ikan menunjukkan signifikansi dimana ikan betina semakin berkurang pada ukuran 120-180 cm, serta tidak ditemukan lagi pada ukuran lebih dari 170 cm. Korelasi nisbah kelamin dan panjang cagak dapat dideskripsikan dengan persamaan regresi sebagai berikut: 1,8013 - 0,0099 FL dengan nilai R2=0,8058.Yellowfin tuna or YFT (Thunnus albacares) is one of the important commodity for the fishing industry in Indonesia because it has the highest catches compared with other tunas. In order to fisheries resources management, it was necessary to monitor the size composition compared between proportion average size captured (Lc) and maturity size (Lm) to meets the size eligibility, as well as the sex ratio as an indicator to estimate the ability of spawn. Data collected by scientific observers program which was following tuna longline operation mainly based in Benoa, Palabuhanratu and Bungus Fishing Port, from August 2005 to November 2013. Chi-Square analysis with 95%confidence level also implemented to determine sex ratio between female and male. The result indicated that YFT were caught has size ranged between 30-179 cm, size mode ranged between 106-110 cm and the mean was 101,65 cm.Mostly YFT (81,03%) was greater than its maturity size (Lm) and that’s mean have been worthy to be captured. Sex ratio of (F:M) 1:1,45 was observed which indicates male was dominant. Correlation between sex ratio and length proved to be significant where the female was diminishing in size between 120-180 cm, even female was no longer found in size more than 170 cm. Correlation between sex ratio and length can described as a regression equation=1,8013 - 0,0099 FL; R2=0,8058.

Published: October 2016

The use of computer technology in manufacturing industries can improve manufacturing flexibility significantly, especially in manufacturing processes; many software applications have been utilized to improve machining performance. However, none of them has discussed the abilities to perform direct machining. In this paper, an integrated system for remote operation and monitoring of Computer Numerical Control (CNC) machines is put into consideration. The integrated system includes computerization, network technology, and improved holding mechanism. The work proposed by this research is mainly on the software development for such integrated system. It uses Java three-dimensional (3D) programming and Virtual Reality Modeling Language (VRML) at the client side for visualization of machining environment. This research is aimed at developing a control system to remotely operate and monitor a self-reconfiguration fixture mechanism of a CNC milling machine through internet connection and integration of Personal Computer (PC)-based CNC controller, a server side, a client side and CNC milling. The performance of the developed system was evaluated by testing with one type of common protocols particularly User Datagram Protocol (UDP). Using UDP, the developed system requires 3.9 seconds to complete the close clamping, less than 1 second to release the clamping and it can deliver 463 KiloByte.

<div data-canvas-width="420.5696489780114">Investigaciones de la estructura de comunidades coralinas sugieren que escalas espacio temporales cortas son responsables de patrones en ecosistemas marinos tropicales. La combinación coral y su zooxantela, u holobionte, puede ser la entidad ecológica modificada por estos factores.

Investigaciones recientes en diversidad de zooxantelas (Symbiodinium</div><div data-canvas-width="243.60164017005522">spp.) han revelado asociaciones de tipo específicas, así como generalistas dependiendo del hospedero. Su distribución depende tanto del hospedero como de las condiciones ambientales. Este estudio determino la identidad molecular de estos simbiontes en comunidades de corales duros (Scleractinia y Milleporina) en 27 localidades en el talud arrecifal superior (zona mixta) en Cartagena, Colombia. La identificación de zooxantelas se realizó mediante análisis de RFLPs (18S, SSU, rDNA, por sus siglas en inglés), DGGE y secuenciación de ADN (ITS2, rDNA). Se encontró variación intra e intercolonial, dependiendo de la especie del hospedero. Se determinaron diferentes holobiontes, como diferentes unidades ecológicas. Estas unidades correspondían a una minoría en la diversidad de especies, pero dominantes (p.ej., Orbicella spp.). Tomando cada holobionte como variable, se realizó un análisis de la estructura comunitaria y fue comparado con un análisis tomando solamente las especies de coral. Mayores similitudes entre estaciones se encontraron cuando se usaron los holobiontes. Las especies dominantes O. annularis</div><div data-canvas-width="10.060996080065763">y O. faveolata formaron en cada caso diferentes holobiontes, dependiendo de la profundidad.

Distribution functions for a family of axially symmetric galaxy models.
Authors: González Guillermo A. , Pedraza Juan F. , Ramos-Caro Javier 
Published: October 2016

<p>Se presenta la derivación de funciones de distribución para los primeros cuatro miembros de una familia de discos, obtenida previamente en González and Reina (2006), la cual representa a una familia de modelos de galaxias axialmente simétricas de radio finito y con densidad superficial de masa bien comportada. Para ello, se emplean varios enfoques desarrollados a partir del par potencial-densidad y, utilizando esencialmente el método introducido por Kalnajs (1976), se obtienen algunas funciones de distribución que dependen de la integral de Jacobi. Ahora, ya que este método exige que la densidad de masa se pueda expresar adecuadamente como una función del potencial gravitacional, solo es posible hacer esto para los primeros cuatro discos de la familia. También encontramos otro tipo de funciones de distribución, comenzando con la parte par de las funciones de distribución anteriores y utilizando el principio de máxima entropía con el fin de encontrar la parte impar y por lo tanto una nueva función de distribución, como fue señalado por Dejonghe (1986). El resultado es una amplia variedad de estados de equilibrio correspondiente a varios modelos auto-consistentes de galaxias planas finitas. © Acad. Colomb. Cienc. Ex. Fis. Nat. 2016.</p>
Una aproximación a la construcción de modelos matemáticos para la descripción de la naturaleza
Authors: Chejne J Farid 
Published: October 2016

<p>Se presenta una descripción de la forma como se afronta el problema de la abstracción mental, necesaria para el desarrollo de un modelo matemático, capaz de describir los fenómenos que rigen el comportamiento de la dinámica de procesos naturales, ante perturbaciones externas al sistema. Una breve revisión desde la dinámica fundamental de Liuoville en la escala cuántica y microscópica, hasta las ecuaciones de balance a escala macroscópica o ecuaciones de Navier-Stokes se ilustra en este artículo. Se resalta el hecho que dividir magnitudes físicas como la velocidad en dos partes, genera la posibilidad de saltar de un escala a otra y se reduce la complejidad y los grados de libertad. La complejidad, se construye a partir de unidades simples; de esta manera, los modelos se consideran una abstracción de la realidad en la que se le asigna una ecuación matemática en diferentes escalas, tanto temporal como espacial, para explicar cómo la naturaleza se comporta y cómo ella se moldea para lograr sus caprichosas formas. La naturaleza toma forma, respetando leyes que rigen su comportamiento ante la influencia ajena y hacen que los eventos naturales se orienten a través de la repetición de una unidad oculta, modificando la forma para adaptase, actuando con el menor gasto energético posible. © Acad.

Medicamentos Não Sujeitos a Receita Médica de Dispensa Exclusiva em Farmácia em Portugal: Uma Oportunidade de Acesso Sub-Aproveitada?
Authors: Martins Ana Paula , Gonçalves Elizabete , Marcelo Ana , Vilão Sergio , Silva José Aranda 
Published: October 2016

Introdução: Em 2013 foi introduzida em Portugal a classificação quanto à dispensa de medicamentos não sujeitos a receita médica de dispensa exclusiva em farmácia, uma subclassificação dos medicamentos não sujeitos a receita médica. A existência desta classificação de medicamentos promove a acessibilidade aos medicamentos, garantindo a eficácia e a segurança na sua utilização, com benefícios para a saúde pública. O presente artigo analisa os medicamentos classificados como medicamentos não sujeitos a receita médica de dispensa exclusiva em farmácia ou com classificação equivalente em sete países europeus, Reino Unido, Dinamarca, Suécia, Noruega, Itália, República Checa e Portugal, e propõe uma lista preliminar das denominações comuns internacionais/ medicamentos que reúnem características que justificariam a sua classificação, em Portugal, como medicamentos não sujeitos a receita médica de dispensa exclusiva em farmácia.Material e Métodos: Para a seleção efetuada, foram analisadas, no universo dos medicamentos autorizados nos países em estudo denominações comuns internacionais/ apresentações que, em pelo menos num dos países considerados, se encontram classificadascomo medicamentos não sujeitos a receita médica de dispensa exclusiva em farmácia ou categoria equivalente, e/ou têm a classificação de medicamentos sujeitos a receita médica em Portugal e medicamentos não sujeitos a receita médica em algum dos países considerados.Resultados: A lista preliminar obtida continha 271 denominações comuns internacionais /apresentações diferentes. Cerca de 19% das denominações comuns internacionais selecionadas não possuíam uma autorização de introdução no mercado válida em Portugal e a maioria (42%) encontra-se classificada em Portugal como medicamentos não sujeitos a receita médica, uma percentagem menor (35%) como medicamentos sujeitos a receita médica, e apenas 4% como medicamentos não sujeitos a receita médica de dispensa exclusiva em farmácia.Conclusão: A segurança constitui um dos fatores mais relevantes a ter em conta no contexto da reclassificação dos medicamentos quanto à sua dispensa ao público. Os dados obtidos permitem uma reflexão acerca da pertinência do alargamento a nível nacional da disponibilidade de medicamentos com a classificação de medicamentos não sujeitos a receita médica de dispensa exclusiva em farmácia, que pelas suas características e indicações terapêuticas a que se destinam, beneficiariam de um acesso sem necessidade de prescrição médica, garantindo a segurança na sua utilização.
Quality of Life in Children with Obsessive-Compulsive Disorder
Authors: Vieira Joana , Ramalho e Silva Filipa 
Published: October 2016

Introduction: Obsessive-compulsive disorder is a psychiatric disorder stated as one of the most debilitating diseases in the developedworld. However, not much is known about how this disease impairs patients’ quality of life in children.Material and Methods: We conducted a research in PubMed and Thomson Reuters Web Of Science using the following terms: ‘Quality of life’, ‘Obsessive-compulsive disorder’, ‘Child’, ‘Pediatrics’ and ‘Adolescent’. Of the 138 papers retrieved with this search, five articles corresponded to the aim of this review. We analyzed quality of life in children with obsessive-compulsive disorder comparing with general population and searching the relation with other clinical variables such as sex, age, comorbidities, symptoms dimension, symptoms severity, family accommodation and quality of life.Results: Albeit studies results not being concordant regarding the different dimensions analyzed, our findings pointed to an overall decrease of quality of life in children with obsessive-compulsive disorder. The presence of co-morbidities, symptoms severity and obsessions with harm/aggression content are the variables that have a higher influence in quality of life levels.Discussion: The small number of articles found and the fact that their methodology was extremely heterogeneous made it difficult to state robust conclusions. Despite that, our findings agree with other studies in adults.Conclusion: Quality of life in children and adolescents with obsessive-compulsive disorder must be better explored in future researches. We suggest the introduction of quality of life as a routinely used instrument in patient’s assessment and in treatment response evaluation.
