Electronic Journal of Biotechnology , 2012,
Abstract: while there is a significant and growing body of knowledge describing the microbial communities of marine invertebrates such as sponges, there are very few such studies focused on octocorals. the octocoral eunicea fusca is common on reefs in various regions of the caribbean and has been the subject of natural product investigations. as part of an effort to describe the microbial community associated with octocorals, a culture-independent analysis of the bacterial community of e. fusca was conducted. specifically, a 16s rdna clone library analysis was performed to provide baseline data. a total of 40 bacteria members from 11 groups were found. in general, proteobacteria were the dominant group with a total of 24 species and α-proteobacteria represented the highest percentage of bacteria associated with e. fusca (27.5%). other prominent groups observed were acidobacteria, actinobacteria, cyanobacteria, planctomycetes, δ-proteobacteria, lentisphaerae and nitrospirae. this is the first analysis of bacterial populations associated with the gorgonian e. fusca.

Abstract: during pregnancy, risk factors such as the high hormonal load and high levels of glucogen allow vaginal colonization and infection by yeasts. objective: to determine the prevalence of candida spp. isolated from samples of vaginal discharge from pregnant women in medellín and to test their sensitivity to antimycotic agents. materials and methods: descriptive study in which 300 pregnant women were tested between february 2006 to june 2007. the prevalence of candida spp. was determined by culture, the yeasts were identified, and the sensitivity to fluconazole and itraconazole was determined by the atb fungus method; the strains with residual growth in fluconazole by such method were submitted to antibiogram by the methods approved by the clsi. results: the prevalence of candida spp. was 33.3% (c. albicans, 77%). all the isolations showed sensitivity to fluconazole. resistance to itraconazole was found in 9% of c. albicans isolates, and in 100% of c. glabrata; 2.5% of the isolates of c. albicans and 100% of c. kefyr resulted sensitive dose-dependent to such antymicotyc. conclusions: c. albicans was the yeast most frequently isolated from vaginal discharge, followed by emergent pathogens such as c. parasilopsis and c. tropicalis. in the studied population, yeasts from the candida gender were still very sensitive to antimycotic agets. it is recommended to identify the yeast to its gender and to perform sensitivity tests in case of therapeutic failure or in recurrent infections.

Abstract: Introducción. En la mujer embarazada, factores como la carga hormonal y los altos niveles de glucogéno favorecen la colonización y la infección vaginal por levaduras. Objetivo. Determinar la prevalencia de levaduras del género Candida, aisladas de muestras de flujo vaginal de un grupo de mujeres embarazadas de la ciudad de Medellín y evaluar la sensibilidad a los antifúngicos. Materiales y métodos. Estudio descriptivo en el cual se estudiaron 300 mujeres gestantes que acudieron a los programas de control prenatal de diferentes IPS de Medellín, en el período de febrero de 2006 a junio de 2007. Se determinó la prevalencia de Candida spp. mediante cultivo e identificación de las levaduras obtenidas, y se determinó la sensibilidad a fluconazol e itraconazol por el método comercial del ATB fungus. A las cepas en las que se evidenció crecimiento residual en fluconazol por dicho método, se les realizó antibiograma por los métodos avalados por el Clinical and Laboratory Standards Institute (CLSI) microdilución M27-A y método de difusión en disco M-44P. Resultados. La prevalencia de Candida spp. fue de 33,3% (C. albicans, 77%; C. parapsilosis, 11%; C. tropicalis, 5%; C. glabrata, 3%; C. guillermondii, 2%; C. kefyr, 1%, y C. famata, 1%). Todos los aislamientos mostraron sensibilidad al fluconazol. Se halló resistencia al itraconazol en 9% de los aislamientos de C. albicans y en 100% de los de C. glabrata. El 2,5% de los aislamientos de C. albicans y el 100% de los de C. kefyr resultaron sensibles dependiente de la dosis a dicho antifúngico. Conclusiones. C. albicans fue la levadura más frecuentemente aislada de flujo vaginal, seguida por patógenos emergentes, como C. parapsilosis y C. tropicalis. En la población estudiada, las levaduras del género Candida son aún ampliamente sensibles a los antifúngicos. Se recomienda la identificación de la levadura a nivel de especie y hacer pruebas de sensibilidad en el caso de falla terapéutica y en infecciones recidivantes. During pregnancy, risk factors such as the high hormonal load and high levels of glucogen allow vaginal colonization and infection by yeasts. Objective: To determine the prevalence of Candida spp. isolated from samples of vaginal discharge from pregnant women in Medellín and to test their sensitivity to antimycotic agents. Materials and methods: Descriptive study in which 300 pregnant women were tested between February 2006 to June 2007.

Abstract: personality has an important role in the way patients with chronic low back pain face pain. some personality features have been associated to the development and the maintenance of chronic pain. studies of chronic low back pain and personality according to the psychobiological model of personality are scarce and will have a heuristic value to promote research in this field. objectives: to compare temperament and character dimensions between patients with chronic low back pain and control subjects; ant to compare personality features between patients with low intensity pain and those with pain of moderate/severe intensity. method: a total of 46 patients with chronic low back pain were recruited from the hospital general de méxico and were matched by age and gender with 46 control subjects. clinical features of the disorder were assessed. personality dimensions were evaluated with the temperament and character inventory (tci). results: patients exhibited higher scores on the temperament dimension "novelty seeking" (ns) and lower scores on "harm avoidance" (ha), also, lower scores were found on the character dimension "cooperativeness" (co). patients with moderate/severe pain reported a tendency to a higher ha. discussion: our results support the attribution fear/avoidance model which presumes that catastrophic interpretations of pain give rise to fear and avoidant behaviors which worsens the pain problem. the study of personality in patients with chronic low back pain gives new information related to the psychosocialinterventions required for these patients.

Abstract: La personalidad impacta sobre la forma en la que las personas con lumbalgia crónica enfrentan el dolor. Se ha identificado la relación entre ciertas características de la personalidad con el desarrollo y mantenimiento del dolor crónico. Los estudios sobre lumbalgia crónica y la personalidad mediante el modelo psicobiológico de la personalidad son escasos y tendrían un valor heurístico para facilitar el desarrollo de investigación en este campo. Objetivos: comparar las dimensiones de temperamento y carácter entre pacientes con lumbalgia crónica y sujetos control; y comparar las características de personalidad entre pacientes con dolor de intensidad leve y aquellos con dolor de intensidad moderada/severa. Método: se reclutaron 46 pacientes diagnosticados de lumbalgia crónica del Hospital General de México y 46 sujetos controles pareados por género y edad. Se evaluaron las características clínicas de la lumbalgia crónica. Las dimensiones de la personalidad fueron evaluadas mediante el Inventario de Temperamento y Carácter (ITC). Resultados: los pacientes mostraron una mayor puntuación en la dimensión de temperamento "búsqueda de la novedad" (NS) y menor puntuación en la "evitación al da o" (HA); así como menor puntuación en la dimensión de "cooperatividad" (CO). Los pacientes con mayor intensidad de dolor mostraron una tendencia a una mayor HA. Discusión: los resultados apoyan el modelo de atribución temor/evitación que asume que las interpretaciones catastróficas del dolor, fomentan el miedo y las conductas evitativas, empeorando el padecimiento. El estudio de la personalidad en pacientes con lumbalgia crónica brinda nuevos conocimientos sobre las áreas de intervención psicosocial requeridas por estos pacientes.

Abstract: ResumenLa proteinuria se define como la cantidad anormalmente elevada deproteínas presente en la orina. Dichas proteínas pueden tener un origen pre-renal, renal o post-renal. Una proteinuria de origen post-renal, a su vez, puede tener causas urinarias o extraurinarias y, generalmente, está asociada a inflamación del tracto urinario inferior. En este estudio se revisaron 162 análisis de orina con sus correspondientes historias clínicas de pacientes procedentes del Hospital Clínico Veterinario de la Universidad de Extremadura (UEx) para conocer las causas relacionadas con la proteinuria post-renal debido a su importancia a la hora de instaurar un tratamiento adecuado. Los resultados demostraron que las cistitis bacterianas y la urolitiasis fueron las causas más comunes de proteinuriapos-renal. La sintomatología clínica encontrada generalmente fue laasociada a inflamación del tracto urinario inferior como hematuria conpolaquiuria y/o disuria.

Abstract:
Language organization in an industrial cluster. Silent romanian immigration in the furniture cluster of Montsià (Catalunya) Organización del lenguaje en un cluster industrial. Inmigración rumana silenciosa en el cluster de empresas de muebles del Montsià (Catalu a)

Abstract: This paper presents the results of a research project on the linguistic and cultural integration of Romanians in an industrial cluster in Catalonia. Fieldwork was undertaken in the area of Montsià (a semi-rural location in southern Catalonia). The furniture firms located there form a cluster of specialised, complementary and labour intensive companies. The use of a foreign labour force (Romanians) that accepts low work and employment standards is the basis of the competitiveness of the cluster. Spanish and Catalan are learnt not because of production or job requirements but because they are assets for integration in the local community. Este estudio presenta los resultados de un proyecto de investigación sobre la integración lingüística y cultural de los rumanos en un clúster industrial de Catalu a. El trabajo de campo se ha llevado a cabo en la comarca del Montsià (una demarcación semirrural del sur de Catalu a). Las empresas de muebles allí localizadas forman un clúster de empresas especializadas, complementarias e intensivas en mano de obra. La competitividad del clúster se basa en el uso de esta mano de obra extranjera (de origen rumano), que acepta unas condiciones laborales y contractuales inferiores. Aprenden el espa ol y el catalán no porque los necesiten para la producción y el empleo, sino porque facilitan su integración en la comunidad local.
Newspapers Coverage of Spain and the United States: A Comparative Analysis  [PDF]

Sociology Mind (SM) , 2012, DOI: 10.4236/sm.2012.21009
Abstract: This article assesses the content of foreign news coverage in the United States and Spain. It draws on content analysis of two U.S. and two Spanish newspapers over a 28-month period, during 2005-2007 and in 2009. The results show that the content of these newspapers tends to be more negative when covering politics. However, there was a major change in the type of coverage in the Spanish newspapers from the period 2005-2007 to 2009. Coverage of U.S. politics in 2009 was much more positive than in the previous period studied. These findings suggest that newspapers contribute to an overall unfavorable representation of these countries for their respective populations. Also, when covering international news, newspapers are less independent from their government agendas than they claim; supporting critical research findings that mainstream media is vulnerable to “news management” by the government.
