“Yo escuché hablar a Borges”: Una experiencia desde la historia oral Favero, Bettina Este artículo resume la experiencia del proyecto de investigación “Las conferencias de Borges”, dirigido por la doctora Mariela Blanco. A partir del año 1949, Jorge Luis Borges comenzó a dictar conferencias y clases en distintas ciudades del país, llegando a un público que en muchas ocasiones no lo había leído. Así, el Borges de la escritura se transformó en un Borges “oral” que, con su forma de hablar, sus tonos de voz y sus gestos, llegó a un público más amplio y se hizo, de alguna manera, más humano...

Modulation optimization when using a splitter pump after the first dimension in comprehensive two- dimensional liquid chromatography Acquaviva, Agustín; Castells, Cecilia Beatriz Marta The rapid growth in the use of two dimensional liquid chromatography (2D-LC) applied to the analysis of moderately to highly complex mixtures, has been fueled by continuous improvements in performance and robustness of the instrument components, as well as the ease-of-use of software necessary for controlling the 2D-LC instrument hardware, and analysis of the large data files that result from this type of work.This work has focused on the evaluation of the performance of an online full comprehensive mode (LC×LC), when an active modulation is implemented using a flow splitter pump placed after the 1D effluent. Two different types of splitting pumps were evaluated: a binary ultra-high pressure liquid chromatography (UHPLC) pump and a high precision syringe pump. We analyzed the performance (reproducibility in peak area and retention times and the 2D peak dispersion) as a function of the location of the active pump Before or After the modulation valve, and the influence of connecting tubes (based on internal diameter and length) necessary between the interface, waste, and the splitting pump. The effect on the flow direction on the filling and flushing of the injection loops at the modulation valve was also analyzed for each pump.In this study, we demonstrate that flow-splitting LCxLC assembly can be performed using either a UHPLC binary pump or a simple syringe pump. Flow splitting after the first dimension is a straightforward strategy to: (i) independently select the 1D column and flow rates with respect to the second dimension; (ii) consciously dilute the eluate according to the solvent characteristics of the second dimension, thereby avoiding 2D peak distortions; and (iii) adapt the injected amount to the second column according to the relative concentration of the components in a complex sample. However, careful consideration of the system setup is necessary. It is demonstrated how experimental results can be significantly affected in terms of peak broadening and reproducibility if optimization of the interface is not taken into account.In addition, under the optimized conditions, the reproducibility in peak area and dispersion in the 2D dimension were evaluated as a function of the amount of sample transferred in terms of percentage of filled loop

Cobaltabis(Dicarbollide) [o-COSAN]− for Boron Neutron Capture Therapy of Head and Neck Cancer: Biodistribution and Irradiation Studies in an Experimental Oral Cancer Model Palmieri, Mónica Alejandra; Monti Hughes, Andrea; Trivillin, Verónica Andrea; Garabalino, Marcela Alejandra; Ramos, Paula Sofia; Thorp, Silvia Inés; Curotto, Paula; Pozzi, Emiliano C. C.; Nuez Martínez, Miquel; Teixidor, Francesc; Viñas, Clara; Schwint, Amanda Elena Boron neutron capture therapy (BNCT) is a tumor-selective particle radiotherapy that combines preferential boron accumulation in tumors and neutron irradiation. Based on previous studies in tumor-bearing mice, this study evaluated the biodistribution of the sodium salt of cobaltabis(dicarbollide) (Na[3,3´-Co(C2B9H11)2], abbreviated as Na[o-COSAN]) in the hamster cheek pouch oral cancer model and the Na[o-COSAN]/BNCT therapeutic effect on tumors and induced radiotoxicity. The synthesis and comprehensive characterization of 10B-enriched trimethylammonium salt of nido-[7,8-C210B9H12]-o-carborane, along with the cesium and sodium salts of [o-10COSAN] cobaltabis(dicarbollide) are reported here for the first time.Methods: Hamsters bearing tumors were injected with Na[o-COSAN] (7.5 mg B/kg) and euthanized at different time-points after injection (30 min, 2, 3, 5, and 18 h post-administration) to evaluate boron uptake in different tissues/organs. Based on these results, tumor-bearing animals were treated with Na[10B-o-COSAN]/BNCT (7.5 mg B/kg b.w., 3 h), prescribing 5 Gy total in absorbed dose to the precancerous tissue surrounding tumors, i.e., the dose-limiting tissue.Results: Na[o-10COSAN] exhibited no toxicity. Although biodistribution studies employing Na[o-COSAN] have shown low absolute boron concentration in the tumor (approx. 11 ppm), Na[o-10COSAN]/BNCT induced a high and significant therapeutic effect on tumors versus the control group (cancerized, untreated animals). Moreover, only half of the animals exhibited severe mucositis in the precancerous dose-limiting tissue after BNCT, which resolved completely at 21 days after irradiation.Conclusions: Na[o-10COSAN] would be potentially useful to treat head and neck cancer with BNCT.

Design and development of nanoprobes radiolabelled with 99mTc for the diagnosis and monitoring of therapeutic interventions in oncology preclinical research Salgueiro, María Jimena; Portillo, Mariano Gastón; Tesán, Fiorella; Nicoud, Melisa Beatriz; Medina, Vanina Araceli; Moretton, Marcela Analía; Chiappetta, Diego Andrés; Zubillaga, Marcela Beatriz Background: Previous studies employing polymeric micelles and molecular imaging for in vivo nanosystem characterization have led to the development of radionanoprobes (RNPs) designed for diagnosing and monitoring therapeutic interventions in preclinical oncology research, specifically within breast and colon cancer models. These models exhibit high GLUT1 expression on tumor cells and VEGFR expression on the tumor vasculature. We aimed to enhance the tumor-targeting specificity of these RNPs by functionalizing micelles with glucose and bevacizumab. The choice of 99mTc to label the nanoprobes is based on its availability and that direct labeling method is a widespread strategy to prepare radiopharmaceuticals using cold reagents and a 99Mo/99mTc generator. Soluplus® is an attractive polymer for synthesizing micelles that also allows their functionalization. With all the above, the objective of this work was to design, develop and characterize nanoprobes based on polymeric micelles and radiolabeled with 99mTc for the characterization of biological processes associated to the diagnosis, prognosis and monitoring of animal models of breast and colon cancer in preclinical research using molecular images.Results: Four RNPs (99mTcTc-Soluplus®, 99mTcTc-Soluplus®+TPGS, 99mTcTc-Soluplus®+glucose and 99mTcTc-Soluplus®+bevacizumab) were produced with high radiochemical purity (>95% in all cases) and stability in murine serum for up to 3 hours. The RNPs maintained the 100 nm size of the Soluplus® polymeric micelles even when they were functionalized and labeled with 99mTc. The image acquisition protocol enabled the visualization of tumor uptake in two cancer experimental models using the assigned RNPs. In vivo biological characterization showed signal-to-background ratios of 1.7 ± 0.03 for [99mTc]Tc-Soluplus®+TPGS, 1.8 ± 0.02 for [99mTc]Tc-Soluplus®, and 2.3 ± 0.02 for [99mTc]Tc-Soluplus®+glucose in the breast cancer model, and 1.8 ± 0.04 for [99mTc]Tc-Soluplus® and 3.7 ± 0.07 for [99mTc]Tc-Soluplus®+bevacizumab in the colon cancer model. Ex vivo biodistribution, showed that the uptake of the tumors, regardless of the model, is <2% IA/g while the blood activity concentration is higher, suggesting that the enhanced permeability and retention effect (EPR) would be one of the mechanisms involved in imaging tumors in addition to the active targeting of RNPs.Conclusions: Soluplus®-based polymeric micelles provide a promising nanotechnological platform for the development of RNPs. The functionalization with glucose and bevacizumab enhances tumor specificity enabling effective imaging and monitoring of cancer in animal models.

Spatial and temporal composition of herbaceous vegetation in Geoffroea decorticans (Gill. Ex Hook. & Arn.) Burkart. thickets Rauber, Ruth Bibiana; Arroyo, D.; Cendoya, Maria Alicia In the Central Semiarid Region of Argentina, the native woody species Geoffroea decorticans has increased in range and density, probably due to overgrazing. The aim of this work was to evaluate the floristic and functional composition of the herbaceous vegetation along time in grazed sites, within thickets of G. decorticans, and compared to grasslands. We registered the cover of each herbaceous species in different locations within thickets and in the natural grassland, at each season for two years, from autumn 2021 to summer 2023. Indicator species of grasslands were found to be mostly palatable native perennials, resulting more homogeneous than those of thickets. Moreover, the mean cover of palatable species was higher in grasslands than in thickets. Consequently, grasslands confer stability and food resource for livestock. Woody thickets would exhibit a decreased stratification from the center to the edge, that would give rise to niche opportunities and biodiversity reservoirs. Temporal variability in floristic composition indicated differences between grasslands and thickets over time, which decreased in spring, probably by homogenization by grazing in winter. The temporal variability of functional composition showed a cyclical variability in all locations that decreased in spring in all cases.

From livestock farming to amateur Botany in the Rio de la Plata: the case of the uruguayan Mariano B. Berro (1838–1919) García, Susana Valeria This paper focuses on the formation of an herbarium and the botanical exchanges conducted by a Uruguayan landowner, Mariano B. Berro (1838–1919), by analysing his archive deposited in the National Archives of Uruguay, which has been neglected as a source for the history of science. This case illustrates the relationship between animal husbandry and the observation and collection of local vegetation, especially the identification of forage plants. In particular, this paper analyses the correspondence between Berro and the Swiss pharmacist and landowner Teodoro Stuckert (1852–1932), who settled in the province of Córdoba, Argentina. Both of them began to assemble botanical collections in the 1890s, and maintained an intense correspondence for nearly 20 years, which provides insights into the practices of a vocational botanist from a rural area in the Rio de la Plata and the role of the network created to exchange specimens, data, and publications within South America as well as with Europe.

Participación del protofeminismo en el proyecto de Estado-nación : Una hipótesis teórico-política (1852-1878); Protofeminism’s Participation in the National State Project: A Theoretical-Political Hypothesis (1852-1878) Losiggio, Daniela El presente artículo se propone analizar la participación que tuvo el pensamiento protofeminista de periodistas, maestras y escritoras del siglo XIX argentino en el proyecto de Estado-nación. Partimos de la hipótesis de que Educación popular (1849) de Domingo Faustino Sarmiento constituye un texto fundante de la formación del Estado-nación argentino y que, tanto el libro como la implementación de su programa, se encontraban en diálogo con estas producciones de mujeres.; This article maintains that the proto-feminist thought of journalists and educators of the Argentine XIX century had a relative participation in the founding of the NationState; more specifically, in the popular education project of Sarmiento. To achieve that goal, we rely on women’s history studies. They allow us to shed new light on the canonical interpretations that, within political theory, reflect on the origin of the Argentine State.

Alcances y cambios de la deuda de hogares en Bahía Blanca; Scope and changes in household debt in Bahía Blanca Cantamutto, Francisco J. El presente artículo presenta los hallazgos en torno a la dinámica de ingresos y deudas de los hogares de Bahía Blanca, Argentina. El estudio de la situación financiera de los hogares ha cobrado relevancia de los últimos años. Desde la agenda de los organismos internacionales de crédito, la agenda de la inclusión financiera es presentada como un instrumento para la lucha contra la pobreza. Sin embargo, los resultados no parecen tan lineales. El financiamiento en los hogares muestra diferencia según la situación socio-económica de los hogares, mostrando diferentes fuentes, motivos y usos. En este artículo se discute esta situación a partir de información cuantitativa recopilada entre 2020 y 2023, período que atraviesa diferentes fases del ciclo económico nacional. Se encuentran impactos diferenciales, que abren la puerta a suponer que la deuda para los hogares esconde situaciones de vulnerabilidad de derechos básicos.; This article presents the findings regarding the dynamics of income and debt of households in Bahía Blanca, Argentina. The study of the financial situation of households has gained relevance in recent years. From the agenda of international credit organizations, the financial inclusion agenda is presented as an instrument for the fight against poverty. However, the results do not seem so linear. Financing in households shows differences depending on the socioeconomic situation of the households, showing different sources, reasons and uses. This article discusses this situation based on quantitative information collected between 2020 and 2023, a period that goes through different phases of the national economic cycle. Differential impacts are found, which open the door to assuming that household debt hides situations of vulnerability of basic rights.

Primer registro de Leopardus braccatus (Carnivora: Felidae) en el bosque seco chiquitano, Bolivia Nogales Ascarrunz, Paola; Aramayo Ledezma, Gabriel; Aliaga Rossel, Enzo; Aramayo Bejarano, José Luis; Lucherini, Mauro; Jansen, Martin El complejo del Leopardus colocolo, según una reciente actualización taxonómica, ha sido dividido en cinco especies. Una de estas es Leopardus braccatus conocida como gato del pantanal, distribuido en Bolivia, Brasil y Paraguay. A pesar de su distribución, esta es una especie poco estudiada. Presentamos aquí un nuevo registro de esta especie, siendo el primero registrado en el bosque seco chiquitano, un ecosistema amenazado que previamente no se consideraba su hábitat. Este hallazgo se llevó a cabo como parte de un programa de monitoreo de felinos con cámaras trampa, donde adicionalmente seis especies de félidos fueron detectadas en un área de 41km2, lo que indica una alta diversidad de felinos en esta ecorregión. Además, se identificaron amenazas directas para el gato del pantanal, como la actividad agrícola y ganadera, los perros domésticos y la cacería ilegal. La relevancia de este nuevo registro radica en su ubicación en el límite occidental-sur de la distribución conocida para Bolivia, así también como sus características morfológicas similares a la especie L. munoai. Esto subraya la necesidad de realizar investigaciones adicionales para comprender mejor su distribución y conservación. Estudios futuros podrían explorar también las similitudes morfológicas y de distribución entre L. braccatus y L. munoai.; The Leopardus colocolo complex, according to a recent taxonomic update, has been divided into five species. One of these is Leopardus braccatus, known as the Pantanal cat, distributed in Bolivia, Brazil, and Paraguay. Despite its distribution, this species remains understudied. Here, we present a new record of this species, the first documented in the dry Chiquitano forest, a threatened ecosystem previously not considered its habitat. This finding was part of a wild felid camera trap monitoring program using camera traps, where additionally six species of felids were detected in a 41km2 area, indicating high felid diversity in this ecoregion. Furthermore, direct threats to the Pantanal cat were identified, such as agricultural activity, presence of livestock, domestic dogs, and illegal hunting. The significance of this new record lies in its location at the southwestern limit of the known distribution for Bolivia, as well as its morphological similarities to the species L. munoai. This underscores the need for further research to better understand its distribution and conservation. Future studies could also explore morphological and distributional similarities between L. braccatus and L. munoai.

A rhodium-catalyzed C–H activation/cyclization approach toward the total syntheses of cassiarin C and 8- O -methylcassiarin A from a common intermediate Vargas Vargas, Didier Farley; Fonzo, Santiago; Simonetti, Sebastián Osvaldo; Kaufman, Teodoro Saul; Larghi, Enrique Leandro Three short and efficient total syntheses of cassiarin C are reported, from a chromanone common key intermediate. A C–H activation strategy, under rhodium catalysis on its pivaloyl oxime, enabled the installation of the pyridine ring. Dehydrogenation of 8-O-methylcassiarin C afforded 8-O-methylcassiarin A. A kinetic experiment and DFT calculations of the intermediates helped to gain insight into the unusual siteand stereo-specific H/D exchange of cassiarin C in CD3OD.

Current understanding, knowledge gaps, and challenges of mountain permafrost research in the Chilean and Argentinean Andes Fernández Navarro, Hans; Tapia Baldis, Carla Cintia; Rojas, Claudia; Derrien, Morgane; Villaseñor, Tania Mountain permafrost extends over a vast area throughout the Chilean and Argentinean Andes, making it a key component of these mountain ecosystems. To develop an overview of the current state of knowledge on southern Andean permafrost it is essential to outline appropriate research strategies in a warmer climate context . Based on a comprehensive review of existing literature, this work identifies eight main research themes on mountain permafrost in the Chilean and Argentinean Andes: paleoenvironmental reconstructions, rock glacier inventories, permafrost distribution models, internal structure analysis, hydrogeochemistry, permafrost dynamics, geological hazards, and transitional landscape studies. This extensive review work also highlights key debates concerning the potential of permafrost as a water resource and the factors influencing its distribution. Furthermore, we identified several challenges the scientific community must address to gain a deeper understanding of mountain permafrost dynamics. Among these challenges, we suggest tackling the need to broaden spatial focus, along with the use of emerging technologies and methodologies. Additionally, we emphasize the importance of developing interdisciplinary approaches to effectively identify the impacts of climate change on mountain permafrost. Such efforts are essential for adequately preparing scientists, institutional entities, and society to address future scenarios.

Para una cartografía de los temas y las preocupaciones de la bibliotecología argentina en las décadas de la profesionalización (1940-1950); Cartography of the Themes of Argentine Librarianship in the Decades of Professionalisation (1940-1950) Planas, Javier Armando En este estudio se propone un relevamiento de los temas que fueron agenda de la bi-bliotecología argentina durante las décadas de la profesionalización (1940-1950). Se tomó como documento de análisis la Bibliografía bibliotecológica argentina, de Nicolás Matijevic (1969), que recopila información publicada entre el siglo XIX y 1967. En primer lugar, se comparó la producción bibliográfica del período de profesionaliza-ción con la etapa anterior y la inmediatamente posterior. En segundo lugar, se revisa-ron y ponderaron los principales temas trabajados por los bibliotecarios. Finalmente, se describen las características elementales de la literatura bibliotecológica durante los años de la profesionalización. Entre otras conclusiones, se destaca la aparición de nuevas temáticas entre las preocupaciones principales de los bibliotecarios, como su propia formación y la bibliotecología y la documentación como disciplinas.; The study proposes a cartography of the topics of interest of argentine librarianship during the decades of professionalisation (1940s / 1950s). The Bibliografía bibliotecológica bibliotecológica argentina, by Nicolás Matijevic (1969), which compiles information published between the 19th century and 1967, is taken as a document for analysis. Firstly, the bibliographic production of the period of professionalisation is compared with the period before and immediately after. Secondly, the main topics worked on by librarians are reviewed and weighted. Finally, the basic characteristics of librarianship literature during the years of professionalisation are described. Among other conclusions, the emergence of new themes among the main concerns of librarians, such as their own training and librarianship and documentation as disciplines, is highlighted.

Burial Histories, Bodies, and Pots: Mortuary Practices in the Southeastern Rainforests of the Andes during the 1st Millennium a.d. (El Cadillal, Argentina) Vazquez Fiorani, Agustina; Kuijt, Ian; Salazar, Julián Through the control of social memory and the dead, household members in Argentinian Andeanearly Formative villages often used primary and secondary mortuary practices to negotiate powerand identity among the living. In this paper, we explore the material evidence obtained in thelarge-scale salvage excavations of El Cadillal, Argentina, where 51 burials were recovered fromthree burial sites. Between A.D. 0 and 900, people living in the southeastern rainforests placeddeceased household members in ceramic urns and, less frequently, inside of rock enclosures andpits surrounded by a range of grave offerings. Drawing upon this case study, we attempt todisentangle the complex web of relationships between the dead, the living, and the El Cadillalcommunity in order to assess how social memories were crafted through primary and secondarymortuary events and how the repetition of mortuary rituals created a social landscape andmemories of the dead.

Caracterización hidroambiental de cuencas en la Reserva Parque Costero del Sur, Argentina; Hydro-environmental characterization of watersheds within the Parque Costero Sur Reserve, Argentina Glustein, Jazmín Ilana; Arturi, Tatiana Sonia; Berardozzi, Eliana; Delgado, María Isabel A pesar de existir una relativa homogeneidad en diferentes característicasde la región pampeana, el tipo de suelo podría determinar los usosposibles en cada zona, con impactos variables en la hidrología, la químicadel agua, la morfología de los cursos y la biodiversidad. En las reservasde biosfera resulta fundamental generar conocimiento que ayude acomprender la relación entre las actividades productivas desarrolladas yel estado de los ecosistemas. El objetivo de este trabajo es caracterizarlas cuencas hidrográficas dentro de la reserva Parque Costero del Sur afin de aportar al desarrollo de una interpretación conceptual delfuncionamiento hidrológico en este territorio. Se estudiaron tres arroyos-Buñirigo, Juan Blanco y Villoldo- con diferentes grados de intervenciónantrópica. Para ello se caracterizaron morfométricamente sus cuencas, segeneraron mapas de uso del suelo y se realizaron balances hídricos. Sellevaron a cabo dos campañas de muestreo de agua superficial y análisisde parámetros fisicoquímicos y microbiológicos. La diferencia en laconcentración de estos parámetros entre campañas resultó significativa.En todos los casos, los valores de Conductividad Eléctrica (CE), turbidezy Demanda Química de Oxígeno (DQO) fueron mayores durante el períodode déficit y los de Fósforo Reactivo Soluble (PRS) durante el período deexceso hídrico. En cambio, la asociación con la distribución espacial de los sitios de muestreo no reveló tendencias claras. Esta investigación podríaresultar útil para la toma de decisiones relacionadas con la gestión delrecurso hídrico, ya que ciertos parámetros exceden los límitesestablecidos localmente.; Despite the relative homogeneity in different characteristics of the Pampas region, the soil type might determine the possible land uses in each area, with variable impacts on hydrology, water chemistry, watercourse morphology, and biodiversity. In biosphere reserves, it is crucial to generate knowledge that helps to understand the relationship between productive activities and the state of the supporting ecosystems. The objective of this study is to characterize the watersheds within the Parque Costero del Sur reserve to contribute to the development of a conceptual interpretation of the hydrological functioning in this territory. Three streams -Buñirigo, Juan Blanco, and Villoldo- with different degrees of anthropic intervention were studied. To achieve this, their watersheds were morphometrically characterized, land-use maps were generated, and water balances were conducted. Two surface water sampling campaigns were carried out, analyzing physicochemical and microbiological parameters. The difference between campaigns for the concentration of these parameters was significant. In every case, the values of Electrical Conductivity (EC), turbidity, and Chemical Oxygen Demand (COD) were higher during the deficit water period and Soluble Reactive Phosphorus (SRP) values during the excess water period. Instead, no clear trends were found regarding the association with the spatial distribution of the sampling sites along the watersheds. This research might be useful for decision-making related to water resource management, as certain parameters exceed locally established thresholds.
