Los poros del exilio
Hochman, Mariano Nicolás
Osvaldo Soriano (1943-1977), escritor y periodista argentino, se exilió a mediados de la década del ?70. Su experiencia en Bélgica y Francia, entre 1976 y 1984, fue fundamental para la escritura de sus novelas, en las que el tema del exilio aparece siempre de un modo sutil, un poco velado y aparentemente secundario, pero que muchas veces funciona como un eje que atraviesa las historias que narra en sus ficciones. En este artículo proponemos un análisis que se enfoca en cómo Soriano transmite al lector una sumatoria de vivencias, tanto en el extranjero como en el retorno a la patria. Un mundo en el que los personajes, que se mueven entre la risa y el grotesco, entre la aventura y heroísmos más bien patéticos, se hallan en una tensión permanente con respecto a su vínculo con el Estado, lo que los lleva a estar desarraigados aun dentro de su propia tierra.
Desde la cordillera al atlántico y desde los hidrocarburos policíclicos a los organométalicos
Desde la cordillera al atlántico y desde los hidrocarburos policíclicos a los organométalicos
Podestá, Julio Cesar
Dentro de mis prioridades nunca estuvo escribir mis memorias. Por ello, cuando me solicitaron la redacción de una reseña autobiográfica necesité un cierto tiempo para analizar la propuesta. Venciendo mi innato perfil bajo y mi sentido autocrítico, consideré interesante ponerme a reflexionar y recordar algunos hitos de mi vida. Así que dejé de pensar en la actualidad y en el futuro, y volví hacia atrás tratando de recordar aquellos hechos que me impresionaron principalmente durante mi niñez y juventud, ya que los posteriores están más cercanos y frescos. En esta reseña incluyo exclusivamente hechos positivos y demostrables. Los negativos me los guardo para poder hacer el balance de mi vida, esperando que al hacerlo el resultado sea que mis aciertos superaron mis errores. El título de la reseña está relacionado, como se verá más adelante, con el recorrido geográfico de mi vida y luego con el inicio y final de mi vida científico-académica. Estoy de acuerdo con los poetas en que los caminos de la vida no son como los imaginamos y que en realidad los hacemos al andar. Al menos en mi caso, hasta aproximadamente los veinte años los caminos fueron marcados por los traslados de mi padre a lo largo y ancho del país. Luego sí, fueron mis decisiones las que me llevaron a construir el camino en cuya fase final me encuentro actualmente.

Reproductive ecology of coypu (Myocastor coypus Molina, 1782) in the Middle Delta of the Paraná River, Argentina; Ecología reproductiva do coipo (Myocastor coypus) no Delta Meio do Río Paraná (Entre Ríos. Argentina)
Courtalon, Paula; Bó, Roberto Fabián; Spina, F.; Jiménez, Nadia Lis; Cantil, Liliana Fernanda; Fernández, R.; Porini, G.
The objective of this study was to estimate and compare some important reproductive parameters of Myocastor coypus over time (June 2006-May 2008), in wetlands of the Middle Delta of the Paraná River (MD) Entre Ríos province, R. Argentina. Within the original coypu distribution range, the MD is among the areas of highest habitat suitability for the species. Coypus were captured and the following reproductive parameters were estimated on a monthly, seasonal and annual basis: pregnancy rate (PR), litter size (LS), gross productivity (GP) and annual production (AP). Statistical non-parametric tests were used for comparisons. Additionally, the expected birth date of each embryo and fetus was estimated by assigning it to a developmental stage category and considering the gestation period of the species. All the parameters showed high values and PR and LS differed significantly between the dry (2006) and humid years (2007). Two peaks of birth were detected, one in spring and another one in mid-autumn. The implications of these results for ensuring the sustainable management of this rodent are discussed.; O objetivo deste trabalho é a descripção e comparação ao longo do tempo (junho 2006 – maio 2008), de diversos parámetros da ecologia reprodutiva de Myocastor coypus nas terras úmidas do Delta Meio do Río Paraná (DM), una das zonas de maior aptidão de hábitat para a espécie dentro da sua área de distribuição original. Com base em capturas de exemplares estimaram-se en forma mensal, sazonal y anual, a taxa de prenhez (TP); o tamanho da camada (TC), a produtividade bruta (PB) e a produção anual (PA) e foram realizadas as comparações correspondentes mediante provas estatísticas não paramétricas. Alem disso, com base no estádio de desenvolvimento dos fetos y embriões observados, levando em consideração a duração do período de gestação, estimou-se quais teriam sido as datas de nascimento mais prováveis. Observaram-se valores relativamente altos para todos os parámetros e diferenças significativas entre as TP y os TC de anos secos (2006) e anos úmidos (2007). Também foram detectados dois picos de parição, um em plena primavera e o outro a meados do outono. Discutem-se as implicâncias destes resultados para assegurar o manejo sustentável do coipo, o principal recurso de fauna silvestre argentina.

The aim of this article is to present results of programmatic introduction of HPV testing with cytologic triage among women 30 years and older in the province of Jujuy, Argentina, including description of the planning phase and results of program performance during the first year. We describe the project implementation process, and calculate key performance indicators using SITAM, the national screening information system. We also compare disease detection rates of HPV testing in 2012 with cytology as performed during the previous year. HPV testing with cytology triage was introduced through a consensus-building process. Key activities included establishment of algorithms and guidelines, creating the HPV laboratory, training of health professionals, information campaigns for women and designing the referral network. By the end of 2012, 100% (n = 270) of public health care centers were offering HPV testing and 22,834 women had been HPV tested, 98.5% (n = 22,515) were 30+. HPV positivity among women over 30 was 12.7%, 807 women were HPV+ and had abnormal cytology, and 281 CIN2+ were identified. CIN2+ detection rates was 1.25 in 2012 and 0.62 in 2011 when the program was cytology based (p = 0.0002). This project showed that effective introduction of HPV testing in programmatic contexts of low-middle income settings is feasible and detects more disease than cytology.
New evidences of rupture of crust and mantle in the subducted Nazca plate at intermediate-depth
New evidences of rupture of crust and mantle in the subducted Nazca plate at intermediate-depth

Between 33°-36°S, the Nazca plate subducts below South American plate with an angle of ~30°, and it is seismically active until ~200-280km depth. At 33.5°S, the seismicity decreases drastically at 120km depth, just below the volcanic arc. In this paper, we studied a pair of associated earthquakes located in the area where the frequency of seismicity changes. The hypocenters of the Mw=6.4, June 16th, 2000 and Mw=5.7 January 7th, 2003 earthquakes were found nearby, adjacent to the oceanic Moho, closely associated with each other. The slip on the plane of the 2000 event produced Coulomb stress changes on the fault plane of 2003, both westward dipping, with a variation from ~1bar near the hypocenter of the latter to ~0.1bars in the deepest part of the plane. The two earthquakes combined process describes a normal focal mechanism, which cuts through the crust and breaks the mantle, reaching depths of ~40km below the Moho.The composed fault plane of the 2000 and 2003 events corresponds to a west-dipping normal fault with strike and dip consistent with those of the outer ridge faults. Thus, these events could be related to a preexisting fault originated in that environment reactivated at depth.The slip on the composed fault plane is consistent with the bending produced by the slab pull. Dehydration could be associated to these events.

Morphological and compositional characteristics of bimetallic core@shell nanoparticles revealed by MEIS
Sanchez, Dario F.; Moiraghi, Raquel; Cometto, Fernando Pablo; Perez, Manuel Alejo; Fichtner, Paulo F. P.; Grande, Pedro L.
In this paper we report the application of a suitable methodology to study the morphology, structure and composition of core@shell nanoparticles (NPs) systems with polydispersity in the shell thickness, with subnanometer resolution and good sampling. Through the combination of Medium Energy Ion Scattering with Transmission Electron Microscopy, we perform a systematic investigation on core@shell Au@Ag NPs synthesized by an original wet chemical method. For samples synthesized with baths of different AgNO3 concentrations, the present approach allowed us to determine the NP's Ag shell thicknesses distribution of about a few nanometers around the Au core.
Shiga toxins and stx phages: highly diverse entities
Shiga toxins and stx phages: highly diverse entities
Krüger, Alejandra; Lucchesi, Paula Maria Alejandra
Shiga toxins are the main virulence factors of a group of Escherichia coli strains [Shiga toxin-producing E. coli (STEC)] that cause severe human diseases, such as haemorrhagic colitis and haemolytic–uraemic syndrome. The Shiga toxin family comprises several toxin subtypes, which have been differentially related to clinical manifestations. In addition, the phages that carry the Shiga toxin genes (stx phages) are also diverse. These phages play an important role not only in the dissemination of Shiga toxin genes and the emergence of new STEC strains, but also in the regulation of Shiga toxin production. Consequently, differences in stx phages may affect the dissemination of stx genes as well as the virulence of STEC strains. In addition to presenting an overview of Shiga toxins and stx phages, in this review we highlight current knowledge about the diversity of stx phages, with emphasis on its impact on STEC virulence. We consider that this diversity should be taken into account when developing STEC infection treatments and diagnostic approaches, and when conducting STEC control in reservoirs.
Identification of pyroxene minerals used as black pigments in painted human bones excavated in Northern Patagonia by Raman spectroscopy and XRD
Identification of pyroxene minerals used as black pigments in painted human bones excavated in Northern Patagonia by Raman spectroscopy and XRD
Tomasini, Eugenia Paula; Favier Dubois, Cristian Mario; Little, Nicole C.; Centeno, Silvia A.; Maier, Marta Silvia
The skeletal remains of seven individuals were excavated in a secondary burial context in the site of Cima de los Huesos, in the San Matías Gulf (Río Negro, Argentina). AMS dating of two samples for this site to 1173 ± 45 and 1225 ± 47 years BP make it one of the earliest burials of its kind uncovered so far in the Patagonian region. Among the findings, the skeleton of a male painted with parallel lines alternating red and black colors was uncovered. SEM-EDS elemental analysis of microsamples removed from the red and the black pigments showed the presence of Mn and Fe as the main components, respectively. Raman microspectroscopy combined with micro-X-ray diffraction analysis showed that the red pigment contains hematite and that the black pigment is composed of members of the pyroxene mineral group, ferrosilite (FeSiO3) and enstatite (MgSiO3) along with kanoite (MnMgSi2O6). This is, to our knowledge, the first report on the use of pyroxenes as black pigments to decorate human remains or archeological artifacts in South America. No organic compounds that could have been used as binders for the paints were detected by FTIR-ATR. Contamination due to quartz and aluminosilicates, mainly microcline and albite, from the burial environment did not allow determining whether clay minerals were used in the paints as binders and/or extenders. The multitechnique approach used was crucial to overcome the limitations of the individual techniques to firmly identify Mn-containing black pigments.
AFLP characterization of three argentine Coprotus species
AFLP characterization of three argentine Coprotus species
Ramos, Araceli Marcela; Tadic, Luis Franco; Policelli, Nahuel; Ferreyra, Laura Ines; Cinto, Isabel Esther
AFLP methodology was applied to characterize three Coprotus species (C. lacteus, C. niveus, C. sexdecimsporus) so as to estimate the levels of polymorphism within species, to analyze the phenetic relationships among them, and to contrast the AFLP findings to those of a previous RAPD study. The high number of AFLP bands obtained with the six assayed primers allowed us to detect intra-specific variability. The genetic variability within species obtained using AFLP (measured in terms of percentage of polymorphic loci) was two to three times higher than those obtained by RAPD. The phenograms generated by AFLP markers grouped all strains of the same species into three defined clusters, and a higher association between C. lacteus and C. sexdecimsporus was also observed. The AFLP technique could become a powerful tool for genera such as Coprotus, in which a high intra-specific homogeneity does not allow detection of genetic variability using other PCR-based markers.

Classical staining and in situ fluorescent hybridization with probes for the 18?5.8?26S and 5Sgenes were performed in Famatinathus decussatus (endemic from Argentina), in order to knowits main chromosomal characteristics and to compare them to related genera. The species is apaleopolyploid with 2n = 54, likely originated from x=9, and its karyotype features are conservative:one pair of 5S signals and two of 18?5.8?26S per complement were found. All the data are congruentwith the basal position of this species in the Asteraceae phylogenies.; Los cromosomas del raro y endémico género Famatinanthus. Se aplicaron tinción convencional e hibridación in situ fluorescente con sondas para los genes de 18–5.8–26S y 5S en Famatinathus decussatus (endémica de Argentina), con el fin de conocer su características cromosómicas principales y compararlas con géneros relacionados. La especie es un paleopoliploide con 2n = 54, probablemente originado a partir de x=9; sus caracteres cariotípicos son conservados: se encontraron un par de señales de 5S por complemento y dos de 18–5.8–26S. Los datos son congruentes con la posición basal que esta especie ocupa en las filogenias de Asteraceae.
Histopathological biomarkers in juvenile silver catfish (Rhamdia quelen) exposed to a sublethal lead concentration
Histopathological biomarkers in juvenile silver catfish (Rhamdia quelen) exposed to a sublethal lead concentration
Muñoz, Lautaro; Weber, Paula; Dressler, Valderi; Baldisserotto, Bernardo; Vigliano, Fabricio Andrés
The aim of this study was to determine the 96-h lethal concentration (96-h LC50) of lead (Pb) in silver catfish, Rhamdia quelen, and to determine histopathological biomarkers in fish exposed for 96-h to a sublethal concentration at 25% of the LC50. The 96-h LC50 was 108 mg l−1. In gills, the length and thickness of lamella and thickness of the filament epithelium were significantly higher in fish exposed to Pb for 48-h than in control fish whereas the interlamellar distance decreased. In the liver, the area occupied by lipid droplets and size of hepatocytes showed significantly higher values after 24-h of exposure. The percentage of abnormal renal tubules was higher in fish exposed to Pb, exhibiting a time-dependent increase. These variations in histopathological biomarkers permit the definition of the overall response of R. quelen to Pb and the potential usefulness in the monitoring of Pb contamination.

Villanova, Gabriela Vanina; Vera, Manuel; Díaz, Juan; Martinez, Paulino; Calcaterra, Nora Beatriz; Arranz, Silvia Eda
Twenty polymorphic microsatellite markers were developed for the Neotropical fish Leporinus obtusidens using a next generation sequencing approach and tested in two other characifomes species, Schizodon platae and Prochilodus lineatus. Microsatellite loci alleles in L. obtusidens ranged between 2 and 20 alleles per locus (mean = 5·7), with expected heterozygosity values ranging from 0·097 to 0·956 (mean = 0·578) and observed heterozygosity values ranging from 0·000 to 0·800 (mean = 0·400) in a sample of 20 specimens from the lower Paraná River (Argentina). Most of these markers will be a valuable tool for captive breeding and stocking programmes, as well as for analyses of population connectivity and genetic structure in this broadly distributed Neotropical migratory fish.
Control de las condiciones ambientales y de iluminación en el Museo Casa Histórica de la Independencia
Control de las condiciones ambientales y de iluminación en el Museo Casa Histórica de la Independencia
Zamora, María Silvana
Los profesionales de los museos son cada vez más conscientes de la importancia del control climático dentro de sus edificios. Los evidentes deterioros sufridos durante las exposiciones han llevado a considerar al ambiente como un agente que decididamente influirá en la integridad de los objetos expuestos, pudiendo afectar en forma definitiva algún elemento de su composición. Más aún, en ciudades históricas, son muchos los museos que se albergan en edificios históricos que no han sido diseñadas para este propósito pero han sido reacondicionados para la exhibición del patrimonio.
El objetivo de este trabajo fue evaluar si las condiciones ambientales a las que se someten dos obras de alto valor histórico del Museo Casa Histórica de la Independencia de la provincia de Tucumán (Argentina) acuerdan con las normas de conservación. Se midió diariamente la temperatura, humedad e iluminación de febrero a abril de 2013. Otro estudio consistió en analizar la carga térmica aportada por grupos visitantes. Los resultados indican que la iluminación es adecuada para la exhibición de este tipo de obras, y no así la temperatura y humedad. El análisis térmico confirma la importancia de restringir el flujo de visitantes para evitar daños aún mayores por variaciones de temperatura.
Expression of the tetrahydrofolate-dependent nitric oxide synthase from the green alga Ostreococcus tauri increases tolerance to abiotic stresses and influences stomatal development in Arabidopsis

Nitric oxide (NO) is a signaling molecule with diverse biological functions in plants. NO plays a crucial role in growth and development, from germination to senescence, and is also involved in plant responses to biotic and abiotic stresses. In animals, NO is synthesized by well-described nitric oxide synthase (NOS) enzymes. NOS activity has also been detected in higher plants, but no gene encoding an NOS protein, or the enzymes required for synthesis of tetrahydrobiopterin, an essential cofactor of mammalian NOS activity, have been identified so far. Recently, an NOS gene from the unicellular marine alga Ostreococcus tauri (OtNOS) has been discovered and characterized. Arabidopsis thaliana plants were transformed with OtNOS under the control of the inducible short promoter fragment (SPF) of the sunflower (Helianthus annuus) Hahb-4 gene, which responds to abiotic stresses and abscisic acid. Transgenic plants expressing OtNOS accumulated higher NO concentrations compared with siblings transformed with the empty vector, and displayed enhanced salt, drought and oxidative stress tolerance. Moreover, transgenic OtNOS lines exhibited increased stomatal development compared with plants transformed with the empty vector. Both in vitro and in vivo experiments indicate that OtNOS, unlike mammalian NOS, efficiently uses tetrahydrofolate as a cofactor in Arabidopsis plants. The modulation of NO production to alleviate abiotic stress disturbances in higher plants highlights the potential of genetic manipulation to influence NO metabolism as a tool to improve plant fitness under adverse growth conditions.

Cadmium (Cd) is one of the most common pollutants in the environment and induces a range of tissue changes or damages and organ dysfunction. The histopathological effects of Cd and lipid peroxidation (LPO) on hepatopancreas of the freshwater shrimp, Palaemonetes argentinus, were studied. Shrimp were obtained from two lagoons with contrasting environmental quality, De los Padres (LP, impacted site) and Nahuel Rucá (NR, reference site), and were exposed to 3.06 and 12.24 µg Cd L−1 for 3, 7, 10 and 15 days. The health status of both populations was also evaluated by histological analysis of control individuals. After exposure, shrimp were transferred to clean water for 28 days to evaluate the recuperation capacity of hepatopancreas. Control shrimp from NR exhibited a normal hepatopancreas structure; unlike control shrimp from LP which showed several alterations. These results were attributed to the different environmental quality of lagoons. The exposure to Cd resulted in several alterations in the histological structure of the hepatopancreas of both populations. The observed alterations included haemocytic and connective infiltrations in the intertubular space, erosioned microvilli, ripple of basal lamina, atrophied epithelium and necrosis, however, the latter was only observed in shrimp from LP. The exposure also caused an increase of LPO levels in both populations. P. argentinus was able to repair the hepatopancreas structure from the damage caused by Cd, evidenced by the histopathological results and LPO levels. Obtained results are indicating that the histological analysis of the hepatopancreas proved to be a highly sensitive method for evaluating water quality, in both environmental and laboratory conditions.
Factors Triggering Cyanobacteria Dominance and Succession During Blooms in a Hypereutrophic Drinking Water Supply Reservoir
Factors Triggering Cyanobacteria Dominance and Succession During Blooms in a Hypereutrophic Drinking Water Supply Reservoir
Fernandez, Carolina; Estrada, Vanina Gisela; Parodi, Elisa Rosalia
As freshwater bodies become enriched in nutrients, there is a shift in the phytoplankton community toward dominance by cyanobacteria. Cyanobacterial blooms are a significant problem in water supply reservoirs worldwide because some species can release toxic compounds and are also associated with the production of bad odor and taste. The aims of this paper were to elucidate the mechanism inducing the development of cyanobacterial blooms and to understand the species succession during the bloom, as well as the influence of abiotic factors on the species composition. Total phosphorus level and parameters related to seasonality, i.e., temperature and solar radiation, were the factors triggering the development of the blooms. Blooms were dominated by Microcystis natans and Anabaena circinalis. Phosphorus was an important limiting factor for Anabaena development but never limited Microcystis growth. Water temperature was optimum until end of February for Anabaena, whereas Microcystis growth was slightly limited since water temperature never reached the optimal. Solar radiation was more limiting than temperature, and the decrease in light had a strong role in the bloom decline. Four species of cyanobacteria recorded in Paso de las Piedras reservoir are potentially toxic: Snowella fennica, Microcystis aeruginosa, Planktothrix agardhii, and A. circinalis, being the last one as the most abundant species during the blooms. Considering the Alert Level Framework for cyanobacteria, alert level 2 was exceeded only during blooms while alert level 1 was exceeded during almost all the year.

La segregación socioespacial, también denominada segregación social del espacio urbano, segregación residencial o simplemente segregación urbana, es un concepto que hace referencia a la existencia de diferencias o desigualdades sociales dentro de un colectivo urbano y al agrupamiento de los sujetos según atributos específicos (socioeconómicos, culturales, raciales, etc.) en conglomerados urbanos con tendencia a la homogeneización en su interior y a la reducción de las interacciones con el resto de los grupos
Defining the Resource Perspective in the Development of Processes-Aware Information Systems
Defining the Resource Perspective in the Development of Processes-Aware Information Systems
Stroppi, Luis Jesús Ramón; Chiotti, Omar Juan Alfredo; Villarreal, Pablo David
Context The resource perspective has impact on the performance of business processes. However, current Workflow Management Systems (WfMSs) provide disparate support to its implementation and business process modeling languages provide limited capabilities for its definition. Thus, it is difficult to specify requirements regarding this perspective and to select an appropriate WfMS to support them in order to obtain a technological solution aligned with the organizational needs. Objective To provide support to the definition, implementation, verification and validation of resource perspective requirements in the development of Process-Aware Information Systems (PAISs) based on WfMSs. Method The following activities were carried out: (i) identification of resource perspective aspects in executable workflow specifications, (ii) analysis of the elements provided by the BPMN modeling language to represent these aspects, (iii) development of a framework based on BPMN for defining and implementing these aspects by using the extension mechanism provided by this language, (iv) development of a model-driven development method that leverages the framework to develop PAISs, and (v) validation of the proposed framework and method through the development of a tool supporting them, a case study, and the evaluation against the Workflow Resource Patterns. Results A framework, a method and a tool that support the definition of the resource perspective in the development of PAISs. Conclusion By using the proposed framework and method, practitioners are able to: define the resource perspective requirements in conceptual process models, select a WfMS as implementation platform, and define the implementation of these requirements maintaining the consistency between the conceptual process models and the workflow specifications.

Representaciones privadas y sentidos colectivos: religión y militancia en las instituciones judías de la Argentina durante la dictadura (1976-1983)
Representaciones privadas y sentidos colectivos: religión y militancia en las instituciones judías de la Argentina durante la dictadura (1976-1983)
Schenquer, Laura
Mientras en la última dictadura militar argentina (1976-1983) el terror inducía a los individuos a retirarse del espacio público al privado, en el campo judío se producía un fenómeno de multiplicación de instituciones adheridas a una corriente religiosa llamada Conservative Judaism. En este artículo se analiza la adhesión del Ateneo de Lomas de Zamora (provincia de Buenos Aires). Se estudian los sentidos y representaciones que circulaban en torno a introducir una práctica religiosa. En esos años en los que las autoridades de la dictadura militar argentina buscaban remodelar a la sociedad y despolitizarla, el Conservative Judaism ofrecía nuclear al campo judío con una propuesta de vida religiosa adaptada a las pautas y normativas de la época.
