Andrea Huneeus,María Gabriela Pumarino,Andrea Schilling,Paz Robledo
Revista médica de Chile , 2009,
Abstract: Background: Chlamydia trachomatis and Neisseria gonorrhoeae are common sexually transmitted diseases among young women and little has been doing to study them in Chilean adolescents. Aim: Determine the rates of C trachomatis and N gonorrhoeae in Chilean young women. Material and methods: Urine samples were obtained from 203 sexually active females under 25 year-old, who attended hospitals from either high or low-income areas in Chile's capital, Santiago. C trachomatis and Ngonorrhoeae were detected by nucleic acid amplification testing. Results: Seven percent of samples were positive for C trachomatis. AU samples were negative for N gonorrhoeae. Among pregnant women, 19% of samples were positive for C trachomatis, while non-pregnant women were positive on 5.5% (p =0.04). Systematic use of barrier contraception was referring by 12% of women. AU of the latter was free of C trachomatis. No association was observing between age, number of sexual partners, age of first sexual intercourse, and presence of uro-gynecological symptoms, socioeconomic status and the rate of C trachomatis. Conclusions: Seven percent of this group of Chilean young women was infected with C trachomatis. The figure rises to 19% if pregnant. Surveillance and screening programs should been implemented to prevent sequels on this vulnerable population.

Características morfológicas de 45 cepas de Microsporum canis
Moreno-Couti?o, Gabriela;Palomares, María de la Paz;Fernández-Martínez, Ramón;Arenas, Roberto;
Revista mexicana de micología , 2009,
Abstract: dermatophytes are pathogen fungi of skin and its appendages. one of them, microsporum spp. has micro and macroscopic characteristics mainly based on the shape and size of macrocon id ia and echinulations that allow the identification of the species. the macro and micromorphological characteristics of 45 m. canis strains were analized with the intention of classifying them into subspecies. all samples had a previous positive direct exam with koh and were cultured in both sabouraud dextrose agar with antibiotic and rice media. thirty five percent grew by the second week. a white velvety colony with a yellowish color on the reversal side was the usual phenotype. fifteen percent of cultures on rice media were negative. the typical m. canis morphology was seen in 81.1% and macroconidia had an average of 9.08 septa. sixteen cases had a mixed morphology. microsporum canis strains are easily identified in most cases, however, in atypical specimens, m. audouinii should be ruled out.

Revista mexicana de micología , 2009,
Abstract: Los dermatofitos son hongos que parasitan la piel y sus anexos. Uno de ellos, Microsporum spp., tiene características macro y microscópicas como forma y tama o de macroconidios y equinulaciones que permiten su identificación entre las diferentes especies. Se analizaron estas características en 45 cepas de M. canis para intentar su clasificación en subespecies. Todas las muestras provenían de pacientes con un examen directo con KOH positivo y los cultivos se realizaron en agar dextrosa de Sabouraud con antibióticos y en un medio con arroz. El 35% de las cepas crecieron en dos semanas. Predominaron colonias blancas y vellosas con reverso amarillento. El 15% no crecieron en el medio con arroz. El 81.1% presentaron características típicas de M. canis y los macroconidios tuvieron en promedio 9.08 septos. En 16 casos las características morfológicas fueron variadas. Los cultivos de Microsporum canis se identifican fácilmente en la mayoría de los casos, sin embargo, en casos dudosos se debe considerar diagnóstico diferencial con M. audouinii.

Revista chilena de pediatría , 2012, DOI: 10.4067/S0370-41062012000100005
Abstract: velocardiofacial syndrome (vcfs) is due to a microdeletion on chromosome region 22q11.2. clinically, it is characterized by congenital anomalies and psychiatric and cognitive manifestations. the most common structural defects are congenital heart disease and palatal anomalies, both due to abnormal development of the pharyngeal pouches. another less studied manifestation is abdominal wall hernias. objective: to characterize the frequency and types of hernias in patients with vcfs, and their association with congenital cardiopathies and palatine abnormalities. patients and methods: 202 patients were evaluated by direct clinical examination and questionnaire about their phenotypic characteristics. results were compared to those found in the literature. results: age range was 0.5 to 48.4 years old (mean 11.9 years), 50.4% were females. twenty two percent of patients had abdominal wall hernias. of these, 49.1% were inguinal and 40.3%, umbilical. conclusion: patients with vcfs have a higher incidence of abdominal hernias than general population, described as approximately 5%. this is another common manifestation of the syndrome, not attributable to defects in development of pharyngeal pouches and with unknown pathogenesis.

Abstract: we analyzed the consequences of aerial spraying with glyphosate added to a surfactant solution in the northern part of ecuador. a total of 24 exposed and 21 unexposed control individuals were investigated using the comet assay. the results showed a higher degree of dna damage in the exposed group (comet length = 35.5 μm) compared to the control group (comet length = 25.94 μm). these results suggest that in the formulation used during aerial spraying glyphosate had a genotoxic effect on the exposed individuals.
Tensiones de la gobernanza en el México rural
Paz, María Fernanda;
Política y cultura , 2008,
Abstract: this paper aims to make some reflections on the concept of governance applied to building cooperative public policy processes in poor and backward regions. our arguments come from a study in a mining region of central mexico, where is taking place a multi stakeholder process that seeks to translate into public policy a risk health management plan. our intention is not to establish generalizations from the empirical data, but contesting the normative approach to governance in light of tensions and contradictions that we see in the process of generating collective agreements of public nature.
Aportes y Desafíos de Estudiar el Voluntariado Desde la Mirada del Sujeto: Análisis de los Hallazgos de Marta, Pozzi y Marzana (2010)
Cadena,María Paz;
Psykhe (Santiago) , 2010, DOI: 10.4067/S0718-22282010000200003
Abstract: this article analyzes the results of the study volunteers and ex-volunteers: paths to civic engagement through volunteerism, by marta, pozzi, and marzana (in this issue), who propose 4 types of volunteers: volunteers in action, volunteers for personal need, active citizens ex-volunteers and ex-volunteers by chance. the discussion builds upon the benefits of a multidimensional approach from the subject's perspective. to accomplish this, its contributions to the understanding of topics, such as the role of motivation in prosocial involvement, the mechanisms that promote this type of behavior, and the differentiation between causes and consequences of it, are analyzed. some ideas are discussed, like the importance of the re-elaboration of motivations, their potential mediating role in the relationship between family and voluntary participation, and the importance of considering in future designs temporal organization that young people themselves give to their experiences. also, some limitations of the study are identified. these are related to religious variables that could explain the results and to the difficulty of establishing whether these results are specific to this form of participation.
LA TRANSFIGURACIóN DE LA IMAGEN: EL ARTISTA, SU OBRA Y EL ESPECTADOR THE TRANSFIGURATION OF THE IMAGE: THE ARTIST, THEIR WORK AND THE SPECTATOR
MARíA PAZ BAJAS
Magallania , 2006,
Abstract: Este trabajo pretende reflexionar acerca de los dispositivos usados por los realizadores audiovisuales en la construcción del indígena en sus relatos fílmicos. Para ello se analizó la película Archipiélago, del cineasta Pablo Perelman, donde encontramos el mecanismo de la transfiguración de la imagen como herramienta fílmica de construcción visual. En Archipiélago se muestra una escena que recrea una antigua película filmada por el sacerdote Alberto María De Agostini. La recreación de estas imágenes, no constituye en sí una transfiguración, sino en el hecho de que ellas se encadenan en una trama fílmica cumpliendo una función en el relato. Las conclusiones obtenidas a partir de la aplicación del modelo desarrollado por Gombrich, que incluye al artista, su obra y el espectador, develaron los elementos que intervienen en la construcción de la imagen indígena transfigurándola en su sentido y forma This work seeks to reflect on the tools used by the filmmakers when constructing the aboriginal in their film stories. For this purpose, the film Archipiélago, by the cinematographer Pablo Perelman, was analyzed, in which we find the mechanism of the image transfiguration as a film tool for visual construction. In Archipiélago a scene is shown that recreates an old film, made by the priest Alberto María De Agostini. The recreation of these images does not constitute a transfiguration in itself, but it does in the sense that they are linked in a film plot that fulfils a function in the story. The conclusions drawn from the application of the model developed by Gombrich, which includes the artist, their work and the spectator, revealed the elements that intervene in the construction of the aboriginal image, transfiguring it in its sense and form.
Digresión y subversión del género policial en Estrella distante de Roberto Bola o Digression and subversion of the crime fiction genre in Roberto Bola o's Estrella distante
María Paz Oliver
Acta Literaria , 2012,
Abstract: Considerando los vínculos de la obra de Roberto Bola o con la narrativa policial, este artículo se propone analizar la relación entre el uso de la digresión y la desestructuración del género policial en la novela Estrella distante. La digresión como recurso destinado a interrumpir el hilo narrativo no sólo tendería a desviar y fragmentar la historia, sino también a modificar el enigma policial. De este modo, nos interesa estudiar cómo a través del constante desplazamiento del enigma la digresión opera como una estrategia subversiva que quiebra la estructura e impide una lectura apegada al género. Considering the relevance of crime narrative in Roberto Bola o's work, this article aim at exploring the relation between the use of digression and the deconstruction of the crime fiction genre. Digression as a technique aimed at interrupting the narration not only tends to deflect and fragment the story, but also to change the notion of mystery. Thus, we propose to study how digression operates through a constant shifting of the mystery as a subversive strategy which breaks the structure and impedes a canonical reading of the genre.
