HAYATI Journal of Biosciences , 2012,
Abstract: Mercury is one of the major pollutant in the environment which is highly toxic. Bioremediation strategies using bacteria have been proposed as an attractive alternative because this is effective, less expensive and more efficient to remove mercury. Brevundimonas sp. HgP1 and Brevundimonas sp. HgP2 were two highly mercury resistant bacteria isolated from a gold mine in Pongkor village with MIC of 575 ppm. The purposes of the research were to study the effect of mercury on bacterial growth and morphological changes of bacterial colony and to measure the ability of bacterial isolates to accumulate Hg2+. The growth was monitored by measuring optical density at 600 nm, whereas accumulation of Hg2+ was measured by mercury vaporation unit. This present studies revealed that the addition of 50 and 100 ppm HgCl2 in Brevundimonas sp. HgP1 resulted in the decreasing of growth rate and the elongation of lag phase in 8 and 16 hours, respectively. The addition of HgCl2 also affected morphological appearance of the bacterial colony to black. Brevundimonas sp. HgP1 accumulated Hg2+ up to 1.09 and 2.7 mg/g dry weight of cells and removed 64.38 and 57.10% Hg2+ from the medium containing 50 and 100 ppm HgCl2, respectively.
La loba y la luciérnaga: La heterogeneidad del discurso poético de Rosabetty Mu?oz y Sonia Caicheo

Acta literaria , 2005, DOI: 10.4067/S0717-68482005000200006
Abstract: this article contains an analysis of the poetic texts of sonia caicheo and rosabetty mu?oz, writers who were born in chiloé. we propose that the poetic discourse of both writers is configured as a heterogeneous and multiple text which is related to the condition -real or fictitious- of marginal subjects and occasionally oral subjects who belong to and are nurtured by an equally heterogeneous culture. we identify the elements that conform the heterogeneity of these poetic discourses and indicate the recurring procedures (motives, figures, images) from which they are constituted. we support our proposal on three theoretical concepts: dialogism or intertextuality, fictitious orality or "recreation of orality" and material imagination. we propose to prove the relevance acquired by the materiality of water and earth in the poetics of caicheo and mu?oz. we believe that the poetry of both sonia caicheo and rosabetty mu?oz is strongly linked to the earth, which is often the element which identifies them

Abstract: itical appraisal on the use of everolimus in renal transplantation as an immunosuppressant to prevent organ transplant rejection Review (5059) Total Article Views Authors: Fernando Giron, Yenny Baez Published Date January 2010 Volume 2010:2 Pages 11 - 14 DOI: http://dx.doi.org/10.2147/TRRM.S5135 Fernando Giron, Yenny Baez Kidney Transplant Service, Colombiana de Trasplantes, Bogota, Colombia Abstract: Everolimus is a proliferation inhibitor designed to target chronic allograft nephropathy including prevention of acute rejection. Acute renal allograft rejection incidence varies with the therapy used for immunosuppression. Registry data show that 15% to 35% of kidney recipients will undergo treatment for at least one episode of acute rejection within the first post-transplant year. Everolimus has been used as therapy with full- or reduced-dose cyclosporine A without evidence of increasing the acute rejection incidence. This review will summarize the available clinical trial data on the use of everolimus and its role in preventing acute rejection incidence in renal transplantation.
Dise o de espacios educativos significativos para el desarrollo de competencias en la infancia Designing meaningful educational spaces for the development of competencies in childhood

Revista CS , 2010,
Abstract: Un espacio educativo significativo es un ambiente de aprendizaje que promueve y fortalece el desarrollo de competencias sociales y cognitivas en los ni os. Este artículo ofrece elementos conceptuales y metodológicos de la psicología educativa que facilitan el dise o de espacios educativos significativos para el desarrollo de competencias infantiles dentro y fuera del aula. Por una parte, se brinda una definición de ambiente de aprendizaje que permite comprenderlo como un espacio dinámico y complejo de construcción de conocimiento. De otra parte, teniendo en cuenta algunas consideraciones sobre la concepción de desarrollo infantil, se establecen cinco criterios para caracterizar los ambientes de aprendizaje como espacios educativos significativos: situaciones estructuradas, intensivas, extensivas, generativas y ricas en formas de interacción. Cada uno de los criterios se ilustra con ambientes de aprendizaje dise ados por agentes educativos de Colombia, basados en el uso de prácticas culturales de sus comunidades de origen. Las prácticas culturales resultaron ser pertinentes para el desarrollo de las competencias de sus ni os. A meaningful educational space is a learning environment that promotes and strengthens the development of social and cognitive competencies in children. This article offers conceptual and methodological elements from Educational Psychology that facilitates the design of significant educational spaces for the development of child competencies, both in and out of school. On the one hand, the learning environment is defined as a dynamic and complex space of construction of knowledge. On the other it takes into account some considerations about child development which help set five criteria to characterize learning environments as meaningful educational spaces: They are structured, intensive, extensive, generative and interactive situations. Each of these criteria is illustrated through learning environments designed by educators in Colombia, based on the use of cultural practices inherent their communities of origin. Cultural practices were found to be relevant to the development of their children’s competencies.
La loba y la luciérnaga: La heterogeneidad del discurso poético de Rosabetty Mu oz y Sonia Caicheo

Acta Literaria , 2005,
Abstract: Análisis de los textos poéticos de Sonia Caicheo y Rosabetty Mu oz, escritoras nacidas en Chiloé. Proponemos que el discurso poético de ambas escritoras se configura como un espacio textual múltiple, heterogéneo, hecho que se relaciona con la condición -real o ficticia- de sujetos marginales y en ocasiones sujetos orales, que pertenecen y se nutren de una cultura igualmente híbrida. Identificamos los elementos que conforman la heterogeneidad de esos discursos poéticos y se alamos los procedimientos recurrentes (motivos, figuras, imágenes) que los constituyen. Nos apoyamos en tres conceptos teóricos: dialogismo o intertextualidad, oralidad ficticia o "recreación de la oralidad" e imaginación material. Pretendemos comprobar la relevancia que adquieren en las poéticas de Caicheo y Mu oz la materialidad del agua y de la tierra. Creemos que tanto la poesía de Sonia Caicheo como la de Rosabetty Mu oz están fuertemente vinculadas a la tierra, siendo muchas veces el elemento que las identifica This article contains an analysis of the poetic texts of Sonia Caicheo and Rosabetty Mu oz, writers who were born in Chiloé.

Radioisotopes "economy of promises": On the limits of biomedicine in public legitimization of nuclear activities
Boudia,Soraya;
Dynamis , 2009, DOI: 10.4321/S0211-95362009000100011
Abstract: this paper aims to examine the rise and the fall of biomedicine in the public legitimization of the development of nuclear energy. until the late 1950s, biological and medical applications of radioisotopes were presented as the most important successes of the peaceful uses of atomic energy. i will argue that despite the major financial investment, the development of the uses of radioisotopes and their important impact on biology and clinical practices, the assessment of medical uses remained relatively limited. as consequence, the place of biomedicine in the public legitimization of financial investment and civilian uses of nuclear energy began to decline from the late 1950s.
Ent?o, minha filha, vamos se afomentar?Puxa??o, parteiras e reprodu??o em Melga?o, Pará
Fleischer,Soraya;
Ciência & Saúde Coletiva , 2008, DOI: 10.1590/S1413-81232008000300011
Abstract: this article presents ethnographic data, collected between 2004 and 2005, about the obstetric service offered by a group of 21 midwives in the city of melga?o, state of pará, brazil. the literature has largely described the work of midwives in brazil and in many other countries around the world. however, there is a kind of practice, which was analyzed very scarcely up to now. the objective of this article is to discuss precisely the practice called puxa??o, an abdominal massage performed mainly on pregnant women to alleviate indispositions, inform the position and sex of the fetus, help define the date and place of delivery, socialize women for maternity and put pregnancy into the context of the local patterns of reproduction, family, well being and health. it can be observed that these midwives offer a very suitable and appropriate pre-natal service, well adapted to the specific needs of the women of the town. even though homebirth has been slowly giving way to hospital birth, this personalized service and practice keeps increasing.
Os cosmopolitas: Kant e os "temas kantianos" em rela??es internacionais
Soraya, Nour;
Contexto Internacional , 2003, DOI: 10.1590/S0102-85292003000100001
Abstract: this article discusses the legacy and limits of the kantian paradigm in international relations. contemporary kantian reconstructions in international relations emphasise the positive aspects of liberal and institutional ideas, although they restrict themselves to the analysis of principles, and do not analyse what impedes the realisation of these principles. the first part of the paper analyses juridical principles that kant established as conditions for peace: 1) pacification of international order depends on democratisation of internal order; 2) relations between states must be subject to international law; 3) individuals must be considered as world citizens, according to cosmopolitan law. the second part shows how these principles have defined and oriented the pacifist movement as well as so-called "utopian-idealism" in the between-wars period. further, it analyses realist criticism of those principles in post-war periods, according to which: 1) democracy in internal order does not influence peace in international order; 2) peace in international relations can be assured not by international law, but by military alliances; 3) cosmopolitan ideals "moralise" international relations, transforming political conflict into a contention between "good" and "evil". finally, it investigates how contemporary analyses orient themselves to kantian principles, as opposed to realism (reason of state). this shows that this paradigm, while necessary, is not sufficient for analyses of international relations, since it does not consider the affirmation of principles in the analyses of hegemonic relations that characterize the international scene.
Uso e circula??o de medicamentos em um bairro popular urbano na Ceilandia, DF
Fleischer, Soraya;
Saúde e Sociedade , 2012, DOI: 10.1590/S0104-12902012000200014
Abstract: in the suburbs of brasilia, family health is taken care of in particular by elderly women. they know the official and non-official shortcuts inside the health system, medicines that each of the family members should take and the places where medicines can be bought cheaper or received for free. they also make experiments with pills and capsules - each ones are strong or dangerous, which ones have to be substituted or combined with different drugs, etc. this paper aims to discuss how informal networks sharing pharmaceutical knowledge and local forms of communication between family members, neighbors and health professionals determine a wider, more complex understanding of health. it is based on an ethnographic research with older residents of guariroba district in ceilandia, df, which are in familiar terms with hypertension and diabetes mellitus. some of the data that support the discussion are the life stories of these migrants towards the federal district (brasilia region, in brasil); the consumption of drugs as a generator of bodily and social experiences of falling ill; self-medication as a practice even after having been seen at the local health agents. this paper wants to emphasize that technical opinion and products offered by official agents of health care did not prevent interviewed women of resorting regularly to a much wider and creative network, neither replaced it. it wants also to show that to perfection this network is a public demonstration of involvement and commitment of these caregivers with their patients' recovery or stability.
