The Effect of Organic Nutrient and Growth Regulators on Seed Germination, Embryo and Shoots Development of Dendrobium antennatum Lindl. Orchid by In Vitro
Authors: Utami Edy Setiti Wida , Hariyanto Sucipto 
Published: October 2016

<p><em>Dendrobium antennatum</em> has high economic value as cut flowers and flowerpots. Like orchid seeds in general, <em>D. antennatum</em> is difficult to germinate under natural conditions. This study aimed to determine the effect of coconut water on seed germination and embryo development, as well as the effect of NAA on shoots development of <em>D. antennatum</em>. This study consisted of two stages. In the first stage, the 12 weeks-old seeds after pollination were sown on MS medium containing 2 g/L peptone + 0%; 5%; 10%; and 20% coconut water. After 8 weeks of culture, the seeds germinated and the shoot formed were recorded. The highest in seed germination (92.2%) and the formation of shoots (51.4%) were obtained when seeds were cultured on MS medium containing 2 g/L peptone + 20% coconut water. In the second stage, the shoots were sub-cultured on MS medium containing 1 mg/L thidiazuron + 0 mg/L; 1 mg/L; 2 mg/L; and 3 mg/L NAA. After 16 weeks of sub-culture, the height of <em>plantlets</em>, the length of the roots and leaves, number of leaves and roots formed were recorded. MS medium containing 1 mg/L thidiazuron + 1 mg/L NAA was the most suitable for the shoots development of <em>D.antennatum</em>. The embryo development of<em> D.antennatum in vitro</em> begins with the enlargement of embryo, with further it emerges from the seed coat (germinated) followed by the formation of the apical meristems to form the shoots and the roots.</p><p> </p>
Desarrollo humano y convergencia en economías de aglomeración: un debate entre Amartya Sen y Paul Krugman
Authors: Racero Mayorca David Ricardo 
Published: October 2016

El presente trabajo plantea un diálogo entre dos de los premios Nobel de Economía más influyentes de las últimas décadas: Paul Krugman y Amartya Sen. La tesis central del trabajo consiste en plantear la necesidad de acudir a la propuesta de política económica adelantada por Sen, referida a “bienes públicos”, para poder generar condiciones de desarrollo no segregacionistas en economías de aglomeración. El presente documento evidencia que el proceso que Krugman describe sobre el crecimiento de las economías de aglomeración deja inevitablemente zonas rezagadas que, por no estar cerca de los centros industriales y de producción, quedan suspendidas en la pobreza. De esta manera, la noción de “desarrollo” más amplia que utiliza Sen hace posible acudir a la generación de mecanismos progresivos que permitan disminuir tal desigualdad mediante políticas distributivas para la ampliación de capacidades. El diálogo conceptual de los dos autores nos posibilita la construcción de un modelo hipotético que tiene como centro la maximización de la utilidad por parte de los hogares (aumento de capacidades en sentido de Sen) en un contexto de aglomeración en perspectiva de Krugman. Al final se realiza una proyección dinámica del modelo mediante la plataforma de simulación Netlogo para soportar la propuesta conceptual.
Dosage Compensation in Drosophila—a Model for the Coordinate Regulation of Transcription
Authors: Kuroda Mitzi I , Hilfiker Andres , Lucchesi John C 
Published: October 2016

Abstract
The sex chromosomes have special significance in the history of genetics. The chromosomal basis of inheritance was firmly established when Calvin Bridges demonstrated that exceptions to Mendel’s laws of segregation were accompanied at the cytological level by exceptional sex chromosome segregation. The morphological differences between X and Y exploited in Bridges’ experiments arose as a consequence of the evolution of the sex chromosomes. Originally a homologous chromosome pair, the degeneration of the Y chromosome has been accompanied by a requirement for increased expression of the single X chromosome in males. Drosophila has been a model for the study of this dosage compensation and has brought key strengths, including classical genetics, the exceptional cytology of polytene chromosomes, and more recently, comprehensive genomics. The impact of these studies goes beyond sex chromosome regulation, providing valuable insights into mechanisms for the establishment and maintenance of chromatin domains, and for the coordinate regulation of transcription.

Oral Effects and Early Implant Survival Results After Imatinib Discontinuation Therapy for Chronic Myelogenous Leukemia: A Case Report
Authors: Dixon Douglas R. , Yassin Alaa 
Published: October 2016

Introduction: Little is known regarding the success, failure, or complication rates of advanced implant procedures in patients after discontinuation therapy of long‐term medications for the treatment of chronic myelogenous leukemia (CML). This case report presents initial results of a case involving implant placement in the mandible and maxilla as well as reduction of palatal oral pigmentation in a patient discontinuing long‐term tyrosine kinase inhibitor (TKI) therapy for CML.Case Presentation: A 57‐year‐old male was referred to the Department of Periodontics, University of Washington, Seattle, Washington, for an assessment of edentulous areas (tooth sites #3 and #14) and failing tooth #19. Previous medical treatment included oral administration (>10 years) of TKI for the treatment of CML. Systemic complications arising from long‐term TKI therapy were treated with discontinuation of this medication. Concurrently, after multispecialty dental and medical consultation, extraction of tooth #19 with immediate implant placement and bilateral sinus augmentation with simultaneous implant placement were successfully performed during three separate surgical appointments. Additionally, marked reduction of oral palatal pigmentation was observed during the surgical and restorative phases after TKI discontinuation.Conclusions: Patients with a history of long‐term TKIs for CML are at risk for developing complications that result in discontinuation of therapy. Long‐term benefits of therapy may allow these patients to enjoy remission with an extended and improved quality of life. Patients undergoing discontinuation therapy may seek dental care. Therefore, dental providers need to understand these systemic interactions and, with multispecialty consultation, may help effectively treat these individuals.

Terapia familiar: una propuesta para resignificar el sentido de familia
Authors: Arbeláez Gallo Ana Isabel , Escobar Serna David Edison , García Duque Francy Elena , Lopera Lopera Juliana 
Published: October 2016

El presente artículo surge con el objetivo de retomar la terapia familiar como una estrategia que permite la resignificación del sentido de familia, en tanto los problemas existentes en su interior, la instauran como un todo; desde esta perspectiva, la teoría general de los sistemas nos dirá que el todo es más que la suma de las partes, de este modo la afectación individual incidirá en el sistema familiar en su completud. La urgencia de la terapia familiar sistémica estará direccionada en potenciar las fortalezas, priorizando los recursos con los que llega a consulta la familia, para lograr de esta manera una construcción focalizada hacia la solución de problemas y nuevos avisoramientos frente al lugar de cada uno de los subsistemas en la grupalidad familiar.
Perdón, convivencia y reconciliación en el proceso de paz, desde una mirada psicológica
Authors: Marín Hinestroza Isamar , Triana Osorio Luz Adriana , Martínez Saldarriaga Mayra Gisella , Alzate Berrio Sara Mileydy 
Published: October 2016

El conflicto armado en Colombia ha perdurado por más de 50 años, tiempo en el que ha acarreado innumerables consecuencias físicas, psíquicas y sociales. Ahora bien, en los últimos años se ha estado abogando por un proceso de negociación con el que se le dé fin a la guerra. En el presente artículo, se pretende abordar los conceptos de perdón, convivencia y reconciliación, puesto que son términos que han estado fuertemente relacionados con los procesos de paz, y que, además, han ganado gran popularidad en el discurso de los colombianos, pero que difícilmente han sido llevados a la realidad. Así las cosas, se plantean algunos aportes que se pueden dar desde la psicología -al hacer intervenciones en instituciones educativas y con familias, para reconocer las pautas de acción que favorecen el proceso de paz; a partir del trabajo comunitario, en el que se reconozca que es en el contexto en que se dan determinadas formas de violencia; promoviendo, tanto desde lo social como lo individual, procesos de perdón, entre otros- para fomentar los procesos de convivencia y reconciliación en el marco del postconflicto.
Psicología Dinámica: epistemología y práctica. El devenir de nuestra profesión
Authors: Jaramillo Serna John Alexander , Uribe Jaramillo Lina Marcela , Rojas Hernández Yuliana Alejandra 
Published: October 2016

Este texto nace del compromiso de un grupo de estudio que se gesta a la luz del gusto, la pasión, la calidad y los procesos de humanización, en una de tantas posibilidades para acompañar al otro. Se reflexiona a partir de las bases epistemológicas de la psicología dinámica, que permiten pensar nuevas construcciones y acciones concretas para el bienestar del ser humano. El primer apartado tiene como objetivo un acercamiento histórico y cronológico del término “dinámica”, abordado desde la psicología y el psicoanálisis. En segunda instancia, se hace referencia a las múltiples miradas del ser humano, nombrando algunos autores que facilitan la comprensión de la subjetividad desde lo relacional, representacional y evolutivo. Finalmente, se exponen algunos aprendizajes y compromisos, generados a partir de la investigación realizada, buscando innovar a través de acciones prácticas con y para el hombre.
Cultura y lenguaje: elementos reestructuradores de la conciencia del ser humano
Authors: Sánchez Trujillo Marcela Patricia 
Published: October 2016

El presente artículo contribuye a la discusión acerca de la coherencia que existe entre lenguaje y cultura, dos aspectos que han recreado y constituido el conocimiento de la humanidad a lo largo de toda su historia. Se trata de mostrar el hecho, bien sabido, de que el lenguaje se construye en la biopraxis; un hecho que pone de relieve una idea notable: el ser humano es un sujeto inacabado, en permanente construcción.
Del “hombre elefante” a “la mujer más fea del mundo”

Published: October 2016

Internet, con su predomino de la imagen han dado un toque nuevo a la vieja agresividad humana, que ahora se deleita, se ensaña con la fealdad, la pobreza, la diferencia y la intimidad del otro. Como en otras épocas, hoy, el ser humano muestra que es despiadado, cruel, brutal con sus semejantes, y que haciendo uso de su inteligencia, ha puesto la tecnología al servicio de esta pulsión agresiva, exhibiendo, publicando, mostrando en las llamadas redes sociales todo lo que es capaz de hacer frente al semejante, mostrando que el semejante siempre es el blanco perfecto de esa agresividad que lo constituye.
Pensamiento sistémico y psicología. Un cambio de paradigma para la comprensión de realidades complejas
Authors: Arbeláez Naranjo Liliana 
Published: October 2016

El creciente interés por el modelo de pensamiento sistémico en la última década y de las ciencias de la complejidad o paradigma de la complejidad, cuyo exponente más reconocido en la actualidad es Edgar Morín, tiene un desarrollo histórico de más de 40 años, que se viene nutriendo de varias corrientes del pensamiento filosófico y científico. En este ejercicio de escritura revisaremos la necesidad que emerge en la época actual de revolucionar el pensar científico y para ello se retomarán los aportes de Thomas Kuhn, defensor del desarrollo y cambio de la ciencia, a la luz de la evolución y del análisis epistemológico de los constructos científicos. Se parte de reconocer dicho cambio como necesario y como producto de un desarrollo histórico, que atraviesa las formas de conocer y producir conocimientos de los seres humanos. De igual manera se hace una breve descripción de los aportes de algunos teóricos en la consolidación del marco epistemológico de las ciencias de la complejidad como marco referencial del pensamiento sistémico y de ellos se rescatan los aportes de la Teoría General de Sistemas y la Cibernética de Segundo orden, evidenciando que en la actualidad a las diversas disciplinas de las ciencias sociales y humanas, se les exige el estudio y la comprensión de una importante cantidad de variables de mayores niveles de complejidad, que reclaman a la academia, a los teóricos y profesionales, ampliar sus marcos de comprensión epistemológica hacia metateorías que faciliten la multireferencialidad. Este ejercicio de escritura se configura, entonces, como una invitación para los profesionales de la psicología, a leer y comprender el momento histórico del cual somos participes como grupo disciplinar.

<p>O presente artigo reflete sobre a importância do espaço e do deslocamento nas narrativas de Ruy Duarte de Carvalho. Fundamental para o alargamento do território literário angolano, a geografia, em sua obra, convida-nos ainda a repensar o lugar das figuras radicalmente excluídas ao longo dos sucessivos regimes de historicidade. Representando as várias faces da alteridade que Angola ainda guarda, esses lugares e personagens permitem ao autor o escrutínio de velhos e novos poderes e, ao mesmo tempo, a criação de veredas para o pensamento artístico e científico. </p>
Eficiência na Gestão Escolar: em Busca das Melhores Práticas em Escolas Municipais Brasileiras do Ensino Fundamental
Authors: Pereira Salgado Junior Alexandre , Chiaretti Novi Juliana , Ferreira Jonas , Mattos Borges de Oliveira Marcio , Miranda Paulo Sergio 
Published: October 2016

O objetivo do artigo é apresentar os resultados de pesquisa empírica realizada em escolas públicas municipais brasileiras do ensino fundamental para evidenciar práticas escolares que podem ter contribuído para o desempenho dos alunos na Prova Brasil. A metodologia aplicada, proposta por Salgado Junior (2013), faz o uso integrado das abordagens quantitativa e qualitativa para se estudar um dado objeto: a eficiência escolar. Assim, por meio de estudos de caso, buscou-se identificar as melhores práticas que podem ter contribuído para o desempenho dos alunos nessas escolas. Os resultados evidenciam que as escolas consideradas eficientes possuem projetos pedagógicos bem estruturados, reflexo das políticas públicas implementadas que são assumidas efetivamente pelo conjunto dos educadores e legitimados por famílias e professores. No entanto, nas escolas consideradas ineficientes há uma maior dispersão das práticas de ensino, com políticas públicas que não se transformam, internamente, em projetos pedagógicos estruturados. Espera-se que os resultados possam exercer um impacto significativo na gestão interna das escolas e alocação de recursos para melhorar o sistema educacional brasileiro.

Published: October 2016

BACKGROUND: Tendons show morphological and vascular adaptations to mechanical loadings. OBJECTIVE: To measure and compare the features of regional microcirculation within the supraspinatus tendon, and to investigate the correlations between those features and shoulder strength in overhead athletes. METHODS: Seventeen badminton athletes were recruited. DCE-MRI was conducted on the tendons in each athlete's dominant arm, including measures for the volume transfer constant (K trans), reverse reflux rate constant(Kep) and the extravascular extracellular space volume (Ve). Isokinetic tests were used to measure the acceleration time and the relative fatigue ratio of the shoulder external rotation of the arm. RESULTS: The DCE-MRI measures for the anterior, posterior, and entirety of the tendon showed regional differences and correlations between the Kep values for the whole supraspinatus tendon and the acceleration time (r = -0.663, p= 0.005) and between the Vp value of the whole tendon and the relative fatigue ratio (r = -0.605, p= 0.01). CONCLUSION: There are differences in the microcirculatory features of the anterior and posterior portions of the supraspinatus tendon. In addition, microcirculation at the supraspinatus tendon and shoulder external rotation explosive strength and fatigue are correlated.

Published: October 2016

BACKGROUND: Isokinetic eccentric cycling is increasingly being utilised to examine the effect of chronic eccentric muscle training however little is known about how individuals familiarise to such a unique training modality. OBJECTIVE: To examine longitudinal variation in power output and lower limb muscle activation during familiarisation to maximal recumbent isokinetic eccentric cycling. METHODS: Twelve male volunteers, unfamiliar with eccentric cycling, completed four trials, separated by 7-10 days, each comprising 6 × 10 s maximal isokinetic eccentric efforts between 20-120 rpm. Peak power and average power output (PO), and surface electromyography (sEMG) of the rectus femoris (RF), vastus lateralis (VL), biceps femoris (BF), and medial gastrocnemius (MG) were recorded throughout. Systematic error across repeated trials was assessed using one-way ANOVA, and random error quantified using coefficient of variation (CV, %). RESULTS: Average PO at 60 rpm and RF activation at 20 rpm increased from trial 1-2 (p < 0.05), with no other systematic error between trials at any cadence. Across all cadences, the CV for peak PO (∼ 13%), average PO (∼ 10%), VL activation (∼ 13%) and RF activation(∼ 19%) was moderate and plateaued after one familiarisation (i.e. T2-T3). However, for BF (∼ 24%) and MG (∼ 22%) activation reliability was generally poor. For the majority of variables the reliability was best at 60 rpm. CONCLUSIONS: Therefore, with one familiarisation, 60 rpm is recommended to achieve moderate between-session reliability in the measurement of power output and lower limb muscle activation during recumbent, eccentric cycling.
Effects of Safinamide on Pain in Fluctuating Parkinson’s Disease Patients: A Post-Hoc Analysis
Authors: Cattaneo Carlo , Barone Paolo , Bonizzoni Erminio , Sardina Marco 
Published: October 2016

Background: Pain, a frequent non-motor symptom in Parkinson’s Disease (PD), significantly impacts on quality of life. Safinamide is a new drug with dopaminergic and non-dopaminergic properties, approved in Europe as adjunct therapy to levodopa for the treatment of fluctuating PD patients. Results from two 24-month, double-blind, placebo-controlled studies demonstrated that safinamide has positive effects on both motor functions and quality of life in PD patients. Objective: To investigate the effects of safinamide on pain management in PD patients with motor fluctuations using pooled data from studies 016 and SETTLE. Methods: This post-hoc analysis evaluated the reduction of concomitant pain treatments and the changes in the scores of the items related to pain of the Parkinson’s Disease Quality of Life Questionnaire (PDQ-39). A path analysis was performed in order to examine direct and indirect associations between safinamide and PDQ-39 pain-related items assessed after 6-months of treatment. Results: The percentage of patients with no pain treatments at the end of the trials was significantly lower in the safinamide group compared to the placebo group. Safinamide 100 mg/day significantly reduced on average the individual use of pain treatments by ≈24% and significantly improved two out of three PDQ-39 pain-related items of the “Bodily discomfort” domain. Path analysis showed that the direct effect of safinamide on pain accounted for about 80% of the total effect. Conclusions: These results suggest that safinamide may have a positive effect on pain, one of the most underestimated non-motor symptoms. Prospective studies are warranted to investigate this potential benefit.

THE FORMATION OF CORES OF GIANT PLANETS AT CONVERGENCE ZONES OF PLANETARY MIGRATION
Authors: Sirono Sin-iti , Katayama Masahumi 
Published: October 2016

ABSTRACT
The formation of solid cores in giant planets of mass

is numerically simulated following the scenario of Sándor et al. In this scenario, there are two convergence zones, corresponding to the outer and inner edges of the dead zone, where the torque exerted on planetary embryos by the gas nebula is zero. At the outer edge of the dead zone, anticyclonic vortices accumulate infalling dust aggregates, and planetary embryos are continuously formed in this scenario. We performed N-body simulations and show that massive objects of

are formed in ∼2.5 Myr, starting from the embryos. The largest object is formed at the inner convergence zone, although planetary embryos are placed at the outer convergence zone. This is due to the scattering of embryos from the outer to the inner convergence zone, and the shorter damping timescale of eccentricity at the inner convergence zone compared to the outer one. We varied the migration timescale due to the torque from gas by changing the gas surface density around the convergence zones. We found that there is a critical migration timescale below which

-sized objects are formed. Furthermore, we conducted simulations in which the gas surface density evolves according to viscous accretion. The largest object is also formed at the inner convergence zone irrespective of the strength of turbulence. Throughout the simulations, the location of the largest mass is the inner convergence zone. We confirmed that the formation timescale of a core of a Jovian planet can be explained in this scenario.
