Lucrecia Martel, escribidora de cartas; Lucrecia Martel, letter writer; Lucrecia Martel, écrivaine prolifique de lettres Kratje, Julia En el cine de Lucrecia Martel, la literatura recibe un tratamiento acústico antes que visual, mientras que en sus cartas aparecen reverberaciones que provienen tanto del cine como de la literatura para abrirse paso como una cineasta implicada en el presente. Si la escritura cristaliza la palabra hablada y la imprenta termina de incrustarla en el espacio visual, tanto las películas como los discursos públicos de Martel, manifiestos en el género epistolar por excelencia, toman el camino inverso: las palabras no son arrancadas del arco sonoro, donde tuvieron su origen en el intercambio humano activo, para relegarlas al orden visual.; Dans le cinéma de Lucrecia Martel, la littérature reçoit un traitement acoustique plutôt que visuel, tandis que dans ses lettres apparaissent des réverbérations venues à la fois du cinéma et de la littérature pour se frayer un chemin en tant que cinéaste impliquée dans le présent. Si l’écriture cristallise la parole et que l’imprimerie finit de l’incruster dans l’espace visuel, les films de Martel comme les discours publics, manifestes dans le genre épistolaire par excellence, prennent le chemin inverse : les mots ne sont pas arrachés à l’arc sonore, où ils ont leur origine dans un échange humain actif, pour les reléguer à l’ordre visuel.; In Lucrecia Martel’s cinema, literature receives an acoustic treatment rather than a visual one, while in her letters reverberations appear to come from both cinema and literature to make her way as a filmmaker involved in the present. If writing crystallizes the spoken word and the printed press finishes embedding it in the visual space, both Martel’s films and public speeches, manifested in the epistolary genre par excellence, take the opposite path: the words are not torn from the sound sphere, where they had their origin in active human exchange, to relegate them to the visual order.

La Eucaristía en el Libro I del Pedagogo de Clemente de Alejandría; The Eucharist in Book I of the Pedagogue of Clement of Alexandria Druille, Paola Ivone El objetivo de nuestro estudio es analizar el pensamiento eucarístico presente en el Libro I del Pedagogo de Clemente de Alejandría a partir de tres problemáticas. En primer lugar, examinaremos los simbolismos proféticos arraigados en prefiguraciones del Antiguo Testamento, las cuales actúan como anticipaciones de la Eucaristía en el Nuevo Testamento. En segundo lugar, nos adentraremos en la noción de la Eucaristía como alimento espiritual, mostrando la conexión intrínseca entre la naturaleza divina, la humanidad encarnada de Cristo y el pneûma como el medio para el acceso al conocimiento de verdades teológicas. Por último, exploraremos interpretaciones adicionales relacionadas con las dos problemáticas anteriores. Estas interpretaciones buscan recuperar referencias de simbolismos anticipatorios y espirituales mediante un análisis de referencias bíblicas significativas.; The aim of our paper is to study the Eucharistic thought present in Book I of the Pedagogue of Clement of Alexandria based on three problems. First, we will examine the prophetic symbolism rooted in Old Testament prefigurations, whichact as anticipations of the Eucharist in the New Testament. Secondly, we will delvein to the notion of the Eucharist as spiritual food, showing the intrinsic connection between the divine nature, the incarnate humanity of Christ and the pneûma as the means to access the knowledge of theologicaltruths. Finally, wewill explore additional interpretations related to the two previous problems. These interpretations seek to recover references of anticipatory and spiritual symbolism through a careful analysis of significant biblical references.

Producción de textos argumentativos en educación secundaria de acuerdo con el desempeño en comprensión: una aproximación psicolingüística; Writing of argumentative texts in secondary education according to performance in reading comprehension: a psycholinguistic approach Chimenti, María de Los Ángeles; Abusamra, Valeria La lectura y la escritura son habilidades lingüísticas culturales fundamentales para el éxito académico. Si bien producir un texto es una actividad cognitivamente más costosa que comprenderlo, ambas actividades comparten componentes lingüísticos y cognitivos subyacentes. El objetivo de este trabajo es determinar si existen diferencias en las características de los textos argumentativos producidos por estudiantes de escuela secundaria de acuerdo con su desempeño en comprensión. Para ello, se evaluó a 59 estudiantes argentinos con una prueba de comprensión y otra de producción de textos argumentativos. Sobre la base de la primera, se identificó un subgrupo de alto y otro de bajo desempeño en comprensión. Mientras que el subgrupo de bajo desempeño en comprensión escribió sin considerar los aspectos retóricos involucrados en la consigna, el subgrupo de alto desempeño en comprensión produjo textos argumentativos que resultaron, en general, más adecuados y de mayor calidad. Estos hallazgos constituyen un aporte al estudio de los vínculos entre comprensión y producción de textos, un área insuficientemente desarrollada en la investigación en español. Además, pueden contribuir a la formulación de estrategias de enseñanza, en particular para estudiantes de escuela secundaria con dificultades.; Reading and writing are fundamental cultural language skills crucial for academic success. Although writing a text is cognitively more demanding than reading, both activities share underlying linguistic and cognitive components. This paper aims to determine whether differences exist in the characteristics of argumentative texts produced by secondary school students based on their reading comprehension performance. To this end, 59 Argentinean students were evaluated using a comprehension test and an argumentative text production test. Based on the comprehension test results, subgroups of high and low comprehension performance were identified. The low comprehension subgroup produced texts without considering the rhetorical aspects of the task, while the high comprehension subgroup wrote more adequate and higher quality argumentative texts. These findings contribute to the study of the relationship between comprehension and text production, an area insufficiently developed in Spanish research. Additionally, they may inform the development of teaching strategies, particularly for secondary school students facing difficulties.

El rol de los agentes del campo cultural en la custodia y producción de colecciones arqueológicas del Área de Ventania (provincia de Buenos Aires, Argentina); The role of agents in the cultural field in the custody and production of archaeological collections in the Ventania Area (Buenos Aires province, Argentina) Oliva, Camila Este trabajo investiga el impacto del coleccionismo arqueológico en el sudoeste de la provincia de Buenos Aires, Argentina, específicamente en los municipios de Tornquist, Saavedra y Puan, ubicados en el área arqueológica de Ventania. La investigación analiza cómo los coleccionistas e investigadores aficionados han influido en la creación y desarrollo de museos locales, así como en la preservación del patrimonio arqueológico de comunidades cazadoras-recolectoras del Holoceno medio. La metodología incluyó estudios biográficos, entrevistas en profundidad con coleccionistas y aficionados, relevamiento de exposiciones museísticas y análisis de redes para entender las conexiones entre actores e instituciones. Los resultados destacan el papel fundamental de estos actores locales como custodios y difusores del patrimonio arqueológico, quienes, a través de sus colecciones y conocimientos, han contribuido significativamente a la preservación y divulgación de la historia regional, aunque fuera del ámbito académico formal. Este estudio aporta una perspectiva crítica sobre la gestión, conservación e investigación del patrimonio arqueológico local.

Imágenes tergiversadas: Plataformas digitales y colectivos artísticos erráticos; Distorted images: Digital platforms and erratic art collectives Martinelli, Lucas Sebastián El objetivo de este artículo es reflexionar sobre los modos en los que en el campo de experimentación estético produce la posibilidad de impugnar los usos de los dispositivos tecnológicos y las nuevas formas de subjetividad vinculadas con las interacciones en las plataformas, para observar la posibilidad de subversión en las mismas. Las imágenes tergiversadas refieren al marco visual de las plataformas que aparecen en el arte como una forma de apelar al malestar de lo digital. Por eso este artículo comienza con un panorama del uso de los datos y las maneras contemporáneas de entender la relación entre las plataformas, las imágenes y los archivos digitales; para luego centrarse en cada uno de los casos a analizar. El video experimental y las prácticas del colectivo Suavecitxs Arf, la obra de danza Coreografías de la vergüenza con sus paratextos y la película El auge de lo humano 3 son tres propuestas artísticas muy distintas que tienen en común los rasgos de disconformidad con el mundo digital en el que cohabitan. A su vez, se trata de objetos paralelos a un conjunto de prácticas de intercambio entre colectivos artísticos que están en tránsito constante entre el mundo material y virtual.; The objective of this article is to reflect on the ways in which the field of aesthetic experimentation produces the possibility of contesting the uses of technological devices and the new forms of subjectivity linked to interactions on platforms, to observe the possibility of subversion. The distorted images refer to the visual framework of the platforms that appear in art as a way of appealing to the discomfort about the digital. That is why this article begins with an overview of the use of data and contemporary ways of understanding the relationship between platforms, images and digital files; and then focus on each of the cases to be analyzed. The experimental video and practices of the Suavecitxs Arf collective, the dance work Coreografías de la vergüenza with its paratexts and the film The Rise of the Human 3 are three very different artistic proposals that have in common the traits of disagreement with the digital world in the one they cohabit. At the same time, these are objects parallel to a set of exchange practices between artistic collectives that are in constant transit between the material and virtual world.

Alamandine, a protective component of the renin-angiotensin system, reduces cellular proliferation and interleukin-6 secretion in human macrophages through MasR–MrgDR heteromerization Rukavina Mikusic, Natalia Lucía; Silva, Mauro Gastón; Erra Diaz, Fernando Alberto; Pineda, Angélica M.; Ferragut, Fatima Eneida del Valle; Gomez, Karina Andrea; Mazzitelli, Luciana Romina; Gonzalez Maglio, Daniel Horacio; Nuñez, Myriam; Santos, Robson A.S.; Grecco, Hernan Edgardo; Gironacci, Mariela Mercedes Alamandine (ALA) exerts protective effects similar to angiotensin (Ang) (1-7) through Mas-related G protein-coupled receptor type D receptor (MrgDR) activation, distinct from Mas receptor (MasR). ALA induces anti-inflammatory effects in mice but its impact in human macrophages remains unclear. We aimed to investigate the anti-inflammatory effects of ALA in human macrophages. Interleukin (IL)-6 and IL-1β were measured by ELISA in human THP-1 macrophages and human monocyte-derived macrophages exposed to lipopolysaccharide (LPS). Consequences of MasR-MrgDR heteromerization were investigated in transfected HEK293T cells. ALA decreased IL-6 and IL-1β secretion in LPS-activated THP-1 macrophages. The ALA-induced decrease in IL-6 but not in IL-1β was prevented by MasR blockade and MasR downregulation, suggesting MasR-MrgDR interaction. In human monocyte-derived M1 macrophages, ALA decreased IL-1β secretion independently of MasR. MasR-MrgDR interaction was confirmed in THP-1 macrophages, human monocyte-derived macrophages, and transfected HEK293T cells. MasR and MrgDR formed a constitutive heteromer that was not influenced by ALA. ALA promoted Akt and ERK1/2 activation only in cells expressing MasR-MrgDR heteromers, and this effect was prevented by MasR blockade. While Ang-(1-7) reduced cellular proliferation in MasR -but not MrgDR- expressing cells, ALA antiproliferative effect was elicited in cells expressing MasR-MrgDR heteromers. ALA also induced an antiproliferative response in THP-1 cells and this effect was abolished by MasR blockade, reinforcing MasR-MrgDR interaction. MasR-MrgDR heteromerization is crucial for ALA-induced anti-inflammatory and antiproliferative responses in human macrophages. This study broaden our knowledge of the protective axis of the RAS, thus enabling novel therapeutic approaches in inflammatory-associated diseases.

Comment on De Rosa et al. Hearing Loss: Genetic Testing, Current Advances and the Situation in Latin America. Genes 2024, 15, 178 Elgoyhen, Ana Belen; Buonfiglio, Paula Inés; Dalamon, Viviana Karina The manuscript "Hearing Loss: Genetic Testing, Current Advances and the Situation in Latin America" by De Rosa et al. includes a comprehensive wealth of data that describe the state of the field in the Latin American region. A detailed demographic and economic landscape is presented, and provides insightful historical perspectives on key genetic advancements in hearing loss (HL) diagnosis. Nevertheless, the paper lacks important additional information concerning the current situation of genetic and genomic medicine in Latin American countries.

Engineering user-centered explanations to query answers in ontology-driven socio-technical systems Teze, Juan Carlos Lionel; Paredes, José Nicolás; Martinez, Maria Vanina; Simari, Gerardo The role of explanations in intelligent systems has in the last few years entered the spotlight as AI-based solutions appear in an ever-growing set of applications. Though data-driven (or machine learning) techniques are often used as examples of how opaque (also called black box) approaches can lead to problems such as bias and general lack of explainability and interpretability, in reality these features are difficult to tame in general, even for approaches that are based on tools typically considered to be more amenable, like knowledge-based formalisms. In this paper, we continue a line of research and development towards building tools that facilitate the implementation of explainable and interpretable hybrid intelligent socio-technical systems, focusing on features that users can leverage to build explanations to their queries. In particular, we present the implementation of a recently-proposed application framework (and make available its source code) for developing such systems, and explore user-centered mechanisms for building explanations based both on the kinds of explanations required (such as counterfactual, contextual, etc.) and the inputs used for building them (coming from various sources, such as the knowledge base and lower-level data-driven modules). In order to validate our approach, we develop two use cases, one as a running example for detecting hate speech in social platforms and the other as an extension that also contemplates cyberbullying scenarios.

Incidence of agroecological-based practices in urban vegetable gardens: effect on crop diversity and production levels de Paz, Manuel; Nabaes Jodar, Diego Nicolás; Ocariz, María Paula; Mantiñan, Camila; Raffo, Fernando; Garibaldi, Lucas Alejandro Agroecological-based practices (ABPs) play a vital role in urban vegetable gardens,enhancing the quality of life. However, factors driving ABP implementation and theirimpact on crop production and diversity are not fully understood. Our study assessedthe influence of socio-economic and environmental characteristics on ABP adoption,crop diversity, and totalTotal weight vegetable production in San Carlos de Bariloche,Argentina. Through interviews and a multi-model inference approach, we found thatABP implementation is tied to gardener experience and formative assets (e.g.,horticultural experience, specific trainingcapacitation). Crop diversity, integral to ABP,is affected by farming practices and farmer characteristics (Farm animals, Pollinator-friendlyFriendly pollinator practices, Experience, Additional training andEnvironmental knowledge). The Totaltotal weight produced was primarily influencedby the type of garden, the gardener´s experience and some ABPs. Long-standingcommercial and community objectives, and the use of farm animals and commercialseed led to greater production. Strengthening key drivers, such as farmer training,through public policies (e.g., income generation, financing, specific training, landaccess) can bolster the role of urban gardens in providing a healthy environment andpromoting food sovereignty.

Wearable Device Dataset from Induced Stress and Structured Exercise Sessions This original dataset contains physiological signals collected during structured acute stress induction and aerobic and anaerobic exercise sessions using a wearable device. Blood volume pulse, motion-based activity, skin temperature, and electrodermal activity were recorded with the Empatica E4, a research-grade wearable. The stress induction protocol involved math and emotional tasks designed to provoke stress responses, interleaved with rest periods. Self-reported stress levels were also recorded during this procedure. For the exercise sessions, distinct routines on a stationary bike were created for aerobic and anaerobic activities. The dataset includes records from 36 healthy volunteers for stress sessions, 30 for aerobic exercise, and 31 for anaerobic exercise. By examining the variations in physiological signals, the effects of these activities can be analyzed. This dataset is a valuable resource for research on stress and exercise detection and classification.

Competitive ability of three native grass species during establishment Scarfó, María Cecilia; Rodriguez, Dana Aylen; Milano, Clara; Loydi, Alejandro Weed resistance is highly desirable in seed used for restoration. Therefore, assessing the competitiveness of target species during germination and establishment stages would help to plan effective restoration projects. Our study aims to assess the impact of competition in seedling establishment, height, leaf number, and aerial biomass of three native perennial forage grasses with different seed sizes. We conducted a competition experiment under greenhouse conditions with three native species Nassella longiglumis, N. tenuis and Piptochaetium napostaense), and one exotic annual species (Avena barbata). Two competition levels were established (with and without A. barbata) and two seeding densities for the perennial species were defined (15 and 30 seeds per pot). Established seedlings, leaf number, height and aerial biomass were measured. Seedling establishment was affected by competition only for N. tenuis. For all three species, N. longiglumis, with the larger seed size, was the least affected by competition. Competition reduced seedling biomass for all three species, with N. longiglumis, with the larger seed size, being the least affected. Increasing seeding density has little effect on the aerial biomass of the weed.The co-occurrence of native perennial species and the annual species A. barbata severely reduces growth, therefore it is important to implement management practices to control annual exotic species and effectively restore grassland ecosystems.

Fumonisins in infant cereals marketed as complementary food in Argentina Cendoya, Eugenia; Nichea, Maria Julia; Romero Donato, Cindy Johana; Zachetti, Vanessa Gimena Lourdes; Monge, Maria del Pilar; Ramirez, Maria Laura Infant cereals are typically the first foods introduced as complementary foods. Cereals used to elaborate complementary foods, such as wheat, maize and rice, are susceptible to mycotoxin contamination. Among mycotoxins, fumonisins have been epidemiologically associated, in humans, with oesophageal cancer, neural tube defects and stunting. Fumonisins have been found in maize and wheat grains in Argentina. In the present study, a survey was conducted to determine their occurrence in 82 wheat-based and multicereal-based infant cereal items collected from retail stores in Rio Cuarto, Argentina, using HPLC-MS. Of these samples, 84% showed FBs contamination with levels ranging from 0.05 to 992 μg/kg). Although FB1 was the most prevalent fumonisin, FB2 was found at higher levels. Most samples had levels below the limit of 200 μg/kg set for Argentinean cereal products for children. The outcome of this survey provides information on the naturally presence of fumonisin in infant cereal intended for children in Argentina, which can be helpful to consider relevant monitoring programmes.

Stuck between rivers: a new species of Ctenomys from northern Argentine Patagonia Mapelli, Fernando Javier; Esquenazi, Sofía Micaela; Teta, Pablo Vicente; Austrich, Ailin; Kittlein, Marcelo Javier; Pereyra Villaurreta, Maria Daniela Renée; Tammone, Mauro Nicolás; Mora, Matias Sebastian Ctenomys (tuco-tucos) is one of the most speciose genera of mammals, with around 70 described species. Recently, therate of new species descriptions within the genus Ctenomys has notably increased, primarily due to recent taxonomic revisionsand surveys in previously unexplored geographic areas. In this study, utilizing both morphological and molecularevidence, we describe a new species of Ctenomys from northern Argentine Patagonia, confined between the Colorado andNegro rivers. This new species is a member of the Magellanicus group displaying close relationships with other speciesdistributed in northern Patagonia and adjacent regions (C. bidaui, C. miguelchristie, C. pontifex, and C. pulcer). The majorrivers in the region (Colorado and Negro rivers) appear to delineate the distributional boundaries of the identified taxa. Wetherefore propose that rivers, acting as natural barriers to dispersal, have significantly influenced the diversity of Ctenomysin northern extra-Andean Patagonia.

Temporal host–symbiont dynamics in community contexts: Impacts of host fitness and vertical transmission efficiency on symbiosis prevalence Gundel, Pedro Emilio; Ueno, Andrea Celeste; Casas, Cecilia; Miller, Tom E. X.; Perez, Luis Ignacio; Cuyeu, Romina; Omacini, Marina Symbiotic associations play a role in plant ecology and evolution, but the outcome of the interaction depends on the life-history traits of the partners and the environmental context. Although symbiosis with vertically transmitted microorganisms should result in mutualism, it is not clear how the transmission process aligns with the outcome of the context-dependent symbiosis. For 3 years, we sampled individuals of an annual plant species that forms symbiosis with a vertically transmitted fungal endophyte, in paired stands of two contrasting vegetation communities (humid mesophytic meadows [HMM]: productive/low stress, and humid prairies [HP]: less productive/high stress). We estimated the prevalence of symbiosis at the population level, and the fitness of the plant, the symbiotic status and vertical transmission efficiency at the individual level. Over 3 years, the prevalence of symbiosis was ≈100% in HMM and ≈75% in HP. Plant fitness was very low and high in years with precipitation below and above the yearly mean, respectively. The higher fitness of endophyte-symbiotic plants was evident in the HMM and high precipitation years. Vertical transmission of endophytes was higher in HMM (≈96%) compared to HP (≈93%) and was not related to plant fitness. Despite transmission inefficiencies in HP, changes in prevalence within the growing season (from seeds to the final plant stand) suggest a fitness advantage for symbiotic plants. Vertical transmission is expected to promote mutualism as it aligns partners' fitness. Although symbiotic plants showed higher fitness and the probability of transmission failures was higher among low-fitness plants, the variation in transmission efficiency between plants and vegetation communities was not related to the fitness of the individual host. Our study provides evidence that context-dependent vertical transmission efficiency and endophyte-mediated fitness advantages interact complexly to determine the prevalence of symbiosis in populations that occur in contrasting vegetation communities.

Interplay of virulence factors and signaling molecules: albumin and calcium-mediated biofilm regulation in Bordetella bronchiseptica Mugni, Sabrina Laura; Ambrosis, Nicolás Martín; O'Toole, George; Sisti, Federico Bernardo; Fernandez, Julieta Bordetella bronchiseptica, a respiratory pathogen capable of infecting various mammals, including humans, is associated with chronic infections, contrasting with the acute infections caused by Bordetella pertussis. Both pathogens can form biofilm-like structures in vivo, providing tolerance against environmental stresses. Biofilm formation by B. bronchiseptica is regulated by the BvgAS two-component system, with intermediate concentrations of certain modulators inducing a phase favoring biofilm formation. Recent studies have highlighted the role of cyclic diguanylate monophosphate (c-di-GMP) in this process: elevated c-di-GMP levels stimulate biofilm formation, whereas phosphodiesterase (PDE) activation reduces biofilms. Respiratory secretions, which contain albumin and calcium at higher concentrations than standard growth media, promote an increase in the amount and extracellular localization of the adenylate cyclase toxin (ACT), an important Bordetella spp. virulence factor. Secreted ACT present in the extracellular media or attached to the outer membrane inhibits biofilm formation. Based on these observations, we hypothesized that serum albumin and calcium together inhibit biofilm formation and explored the potential role of c-di-GMP in this process. Our findings demonstrate that serum albumin and calcium inhibit B. bronchiseptica biofilm formation by two apparently independent mechanisms, increasing AC secretion and inducing c-di-GMP degradation. This study contributes to the understanding of the mechanisms governing B. bronchiseptica biofilm formation and its modulation by host factors.

Li decorated graphdiyne nanosheets: A theoretical study for an electrode material for nonaqueous lithium batteries Jiménez, María Julia; Juan, Julián; Sandoval, Mario German; Bechthold, Pablo Ignacio; Jasen, Paula Verónica; Gonzalez, Estela Andrea; Juan, Alfredo In this work, Density Functional Theory (DFT) is used to study pristine and defectiveGDY. We investigate the effect of Li atom adsorption on the electronic and structuralproperties of this 2D material. In both cases, the Li atom is located at the corner of thetriangular-like pore (H1), but with a slight shift for the defective system. In the perfectsystem, the Li-C bond distances range from 2.289 Å to 2.461 Å, while in the defectivecase, they range from 2.237 Å to 3.184 Å. In the perfect case, the GDY-Li systembecomes metallic and the Li 2s states are stabilized. Charge transfer to the surfacesoccurs near the vicinity of the Li atom. The C vacancy generates new C=C bonds similarto double bonds, enhancing the interaction with Li through strong conjugation. After Liadsorption, the sum of bond order for all the C atoms increases in both structures,from 0.4% to 6%. The Li storage capacity without significant restructuring is six Liatoms. When the atom concentration increases, the OCV values for Li decrease from 0.93 V to 0.23 V. For defective GDY, the specific capacity is 788 mAhg-1, which isslightly higher than for pristine case.
