Abstract	This article aims to analyze some of the reasons that scientific research should be done in public universities in Paraguay. The importance of research to the development of human resources and highlights not only preparing generating high but also because it stimulates curiosity, innovation and creativity. It thus builds the foundation for the development of the country. In this work the need for greater coordination between the science and technology agencies and universities on the platform of applied research and technology is emphasized. It thus seeks to answer one of the many national problems such as inter-agency cooperation as a route for the transfer of information generated for achieving a better country. As a result, it emphasizes the influence of research activities in today's culture, as well as the importance for the assessment of the universities themselves

Abstract	La motivación para este trabajo de investigación es hacer entrega del diagnóstico del uso de la tecnología digital en bibliotecas en el Paraguay, tomando como muestra aquellas que se ubican en los centros referentes o cabeceras de educación, en el país denominadas instituciones centro. Objetivando la labor investigativa en mejorar la disponibilidad y el acceso al material informativo en beneficio de la educación e investigación. Para la recolección de datos se utiliza la técnica de la observación y la entrevista no estructurada con el personal de la biblioteca, y a referentes nacionales en desarrollo de tecnología. De este modo, se presenta la incursión de la tecnología, dando apreciaciones nacionales en los conceptos TIC, brecha digital y alfabetización informacional. A conocimiento que las bibliotecas son centros para la información, recreo y cultura, el uso y la aplicación de la tecnología digital es considerado apropiado y necesario en el apoyo a la gestión bibliotecaria, con uso de la tecnológica. La calidad y la excelencia en la gestión bibliotecaria está dada en los servicios que ella presenta a su entorno, su comunidad, por ende, el usufructo de la tecnología ubica a la unidad de información o Biblioteca como referente del avance país en aras a ser protagonista de las innovaciones tecnológicas con el crecimiento del conocimiento de la ciudadanía en la alfabetización, comunicación y uso de la información facilitado por la misma. Se logra la incursión paulatina de los ciudadanos a la tecnología, con objetivos de la labor investigativa, en el fomento de la distribución de la información a través de la tecnología, desarrollando bases de datos y la conformación de redes en pos a la mejora de la disponibilidad y acceso a los materiales de información. Resultante de este proceso el efecto cooperativo y colaborativo de la unidades de información en la acopio de información en bien directo a la comunidad educativa.

Abstract	The GB virus C is a common non-pathogenic virus, member of the Flaviviridae family with worldwide distribution. Favorable clinical course and reduced mortality among HIV-infected patients was demonstrated by several studies with patients co-infected with the GB virus C (GBV-C). This potential benefit of GBV-C has been demonstrated in the pre-HAART and post-HAART eras; however, this effect was not observed in all studies and the discrepancy may be due to changes during the course of HIV infection, characteristic of the cohort, and the degree of therapeutic response. The GBV-C has been found to decrease HIV replication in in vitro models, highlighting the interference of persistent GBV-C viremia. The mechanism of the beneficial effect of GBV-C appears to be mediated by changes in the cellular immune response, and elucidation of putative protective effects of GBV-C in HIV co-infection could potentially identify novel targets for anti-HIV agents.

Abstract	An interesting interaction pattern has been found between HIV-1 and GBV-C/HGV, resulting in protection against progression to AIDS. The mechanisms involved in this interaction remain to be clarified. We examined the current knowledge concerning this coinfection and developed hypotheses to explain its effects. A better understanding of this interaction could result in new concepts, which may lead to new strategies to control HIV-1 replication and progression to AIDS.

Abstract	Background: Genetic variability is a major feature of the human immunodeficiency virus type 1 (HIV-1) and considered the key factor to frustrating efforts to halt the virus epidemic. In this study, we aimed to investigate the genetic variability of HIV-1 strains among children and adolescents born from 1992 to 2009 in the state of Sao Paulo, Brazil. Methodology: Plasma and peripheral blood mononuclear cells (PBMC) were collected from 51 HIV-1-positive children and adolescents on ART followed between September 1992 and July 2009. After extraction, the genetic materials were used in a polymerase chain reaction (PCR) to amplify the viral near full length genomes (NFLGs) from 5 overlapped fragments. NFLGs and partial amplicons were directly sequenced and data were phylogenetically inferred. Results: Of the 51 samples studied, the NFLGs and partial fragments of HIV-1 from 42 PBMCs and 25 plasma were successfully subtyped. Results based on proviral DNA revealed that 22 (52.4%) patients were infected with subtype B, 16 (38.1%) were infected with BF1 mosaic variants and 4 (9.5%) were infected with sub-subtype F1. All the BF1 recombinants were unique and distinct from any previously identified unique or circulating recombinant forms in South America. Evidence of dual infections was detected in 3 patients coinfected with the same or distinct HIV-1 subtypes. Ten of the 31 (32.2%) and 12 of the 21 (57.1%) subjects with recovered proviral and plasma, respectively, protease sequences were infected with major mutants resistant to protease inhibitors. The V3 sequences of 14 patients with available sequences from PBMC/or plasma were predicted to be R5-tropic virus except for two patients who harbored an X4 strain. Conclusions: The high proportion of HIV-1 BF1 recombinant, coinfection rate and vertical transmission in Brazil merits urgent attention and effective measures to reduce the transmission of HIV among spouses and sex partners.
