Fundación Manuel H.

El proyecto “A través del lente de Manuel H.” plantea diseñar una Fundación cuya misión es fortalecer y reconstruir la memoria de Bogotá a partir de los relatos históricos expresados en las imágenes capturadas por el Maestro Manuel H entre 1946 y 2009. Se trabajará dicho fortalecimiento a partir de tres líneas de productos que se desarrollarán durante los seis primeros años de existencia de la Fundación. Las líneas de servicios que se plantean desarrollar inicialmente, hacen referencia a exposiciones innovadoras utilizando los nuevos conceptos de las artes visuales, actividades académicas y proyectos de responsabilidad social enfocados a la fotografía, las temáticas de la colección y al Maestro Manuel H.

Structural Chromosomal Alterations Induced by Dietary Bioflavonoids in Fanconi Anemia Lymphocytes

Introduction Fanconi anemia is an autosomal recessive disease characterized by a variety of congenital abnormalities, progressive bone marrow failure, increased chromosomal instability and higher risk to acute myeloid leukemia, solid tumors. This entity can be considered an appropriate biological model to analyze natural substances with possible genotoxic effect. The aims of this study were to describe and quantify structural chromosomal aberrations induced by 5 flavones, 2 isoflavones and a topoisomerase II chemotherapeutic inhibitor in Fanconi anemia lymphocytes in order to determine chromosomal numbers changes and/ or type of chromosomal damage. Materials and methods Chromosomes stimulated by phytohaemagglutinin M, from Fanconi anemia lymphocytes, were analysed by conventional cytogenetic culture. For each chemical substance and controls, one hundred metaphases were evaluated. Chromosomal alterations were documented by photography and imaging analyzer. To statistical analysis was used chi square test to identify significant differences between frequencies of chromosomal damage of basal and exposed cell cultured a P value less than 0.05. Results There were 431 chromosomal alterations in 1000 metaphases analysed; genistein was the more genotoxic bioflavonoid, followed in descendent order by genistin, fisetin, kaempferol, quercetin, baicalein and miricetin. Chromosomal aberrations observed were: chromatid breaks, chromosomal breaks, cromatid and chromosomal gaps, quadriratials exchanges, dicentrics chromosome and complex rearrangements. Conclusion Bioflavonoids as genistein, genistin and fisetin, which are commonly present in the human diet, showed statistical significance in the number of chromosomal aberrations in Fanconi anemia lymphocytes, regarding the basal damage.

Especímenes antropométricos y curiosidades pintorescas: la orquestación fotográfica del cuerpo “negro” (Brasil circa 1865)

Paul Gilroy escribe en Against Race que la “producción de la raza” desencadenada en los siglos XVIII y XIX “necesitó una síntesis de logos e ícono, de la racionalidad científica formal acompañada de algo más, algo visual y estético” (1). A partir del siglo XIX y de la mano de los avances tecnológicos en el ámbito de la representación visual, especialmente en la fotografía, los discursos científicos de la alteridad acogen y desarrollan un componente de exhibicionismo y espectacularización.En este marco de ideas, se pretende entender la producción fotográfica del cuerpo “negro”, en específico algunas imágenes que conforman los archivos fotográficos creados por el científico Louis Agassiz y Christiano Júnior en Brasil a mediados del siglo XIX. Objetivo: indagar la manera en que estos procedimientos de visualización contribuyeron a re-ensamblar discursos raciales en Brasil y en Estados Unidos justo en el momento cuando el cuerpo “negro” se enviste de subjetividad legal.

Informal housing in the XXI century. Characteristics of the informal land and housing supply in Bogota during the first decade of the XXI century

This article characterizes the conditions of the informal land and housing supply during the first decade of the xxi century in Bogota, regarding magnitude and location of the informal urban growth (new occupations in the periphery and informal densification of consolidated areas), housing  conditions in recent occupations and the characteristics of the land market. The situation of the  last decade has been reconstructed based in aerial photography analysis, census data quantification  and data analysis from planning and control public entities. Results suggest that due to the relative  land scarcity in Bogotá, among other aspects, the informal market dynamics have experimented changes compared to previous decades, because the growth in consolidated urban areas becomes  more important than the informal urbanization of the peripheries, but at the same time informality  transcends the municipal perimeter to the neighboring municipalities.
