Shifts in the gut microbiota of sea urchin Diadema antillarum associated with the 2022 disease outbreak Ruiz Barrionuevo, Juliana María; Kardas, Elif; Rodríguez Barreras, Ruber; Quiñones Otero, Marcos A.; Ruiz Diaz, Claudia P.; Toledo Hernández, Carlos; Godoy Vitorino, Filipa Introduction: In recent decades, Caribbean coral reefs have lost many vital marine species due to diseases. The well-documented mass mortality event of the long-spined black sea urchin Diadema antillarum in the early 1980s stands out among these collapses. This die-off killed over 90% of D. antillarum changing the reefscape from coral to algal-dominated. Nearly 40 years later, D.antillarum populations have yet to recover. In early 2022, a new mortality event of D. antillarum was reported along the Caribbean, including Puerto Rico. Methods: This study identifies the gut microbiota changes associated with the D. antillarum during this mortality event. It contrasts them with the bacterial composition of gut samples from healthy individuals collected in 2019 by using 16S rRNA sequencing analyses. Results: Notably, the die-off group’s core microbiome resembled bacteria commonly found in the human skin and gut, suggesting potential anthropogenic contamination and wastewater pollution as contributing factors to the 2022 dysbiosis. The animals collected in 2022, especially those with signs of disease, lacked keystone taxa normally found in Diadema including Photobacterium andPropionigenium.Discussion: The association between human microbes and disease stages in the long-spined urchin D. antillarum, especially in relation to anthropogenic contamination, highlights a complex interplay between environmental stressors and marine health. While these microbes might not be the direct cause of death in this species of sea urchins, their presence and proliferation can indicate underlying issues, such as immune depletion due to pollution, habitat destruction, or climate change, that ultimately compromise the health of these marine organisms.

Effect of probiotics on the growth, blood profile, and nutritional-metabolic profile of feedlot cattle Mansilla, Flavia Ivana; Aristimuño Ficoseco, Maria Cecilia; Miranda, Maria Hortencia; D'urso Villar, Marcela Adriana; Fátima Nader Macias, María E.; Vignolo, Graciela Margarita The blood profile, nutritional-metabolic status, and growth performance of cattle receiving probiotic lactobacilli for 105 days from entry to a feedlot system were evaluated. The trial involved 60 Brangus/Braford castrated steers. They were randomly allocated in pens (n = 15/treatment) and in-feed supplemented with different probiotic suspensions (107–108 CFU/mL/day). The suspensions consisted of (A) Lactobacillus acidophilus CRL2074, (B) Limosilactobacillus fermentum CRL2085, or (C) multistrain CRL2074 + CRL2085 + Limosilactobacillus mucosae CRL2069 formulations, against the control group. Individual samples were taken from each animal thrice throughout the assay (0, 45, and 105 days). Analysis of clinical parameters showed optimal animal body condition and sensorium state. Isolated nasal discharges and the absence of diarrhea were observed at 105 days in the group administered with multistrain and Lim. fermentum CRL2085 probiotics. An increasing trend was observed in cattle growth throughout the trial, which was calculated based on the height at the withers and the thoracic diameter. Weight increase and daily weight gain (1.31 ± 0.12 kg and 1.21 ± 0.21 kg/day, respectively) were maximum for cattle supplied with CRL2085 and multistrain probiotics. Blood and serum parameters were within referential ranges for the control and probiotics-supplemented groups; however, mean values of hematocrit were higher, while the serum glucose, lipid profile, and C-reactive protein values were lower in all the groups. In addition, the multistrain probiotic formulation exhibited higher numbers of cultivable lactic acid bacteria and a slight decrease in the number of enterobacteria in feces at the end of the trial. Therefore, there is great potential for multistrain probiotic formulation to improve the overall performance of feedlot beef cattle.

Update on Endogenous HNO Production: An Exploration of Unanswered Questions and Challenges Vargas, Paola Elizabeth; Doctorovich, Fabio; Suarez, Sebastian This review consolidates the evidence supporting endogenousHNO generation through enzymatic and non-enzymatic pathways,emphasizing advancements in real-time HNO sensingwithin living systems. Azanone (nitroxyl, HNO) is the oneelectron-reduced congener of nitric oxide (NO*) and sharesvarious biological actions. HNO exhibits unique properties,including positive inotropic and lusitropic effects, along withresistance to scavenging by reactive oxygen species (ROS),particularly superoxide. Research on HNO has intensified overthe last two decades, focusing on its reactivity and the prospectof endogenous formation due to its potential significance. Thehigh reactivity of HNO arises from reactions with biologicallyrelevant species such as oxygen, NO*, and thiols, as well as selfdimerization.Detecting and quantifying HNO has posedchallenges, initially relying on nitrous oxide (N2O) detection, abyproduct of dimerization. Recent advancements, includingfluorescent probes and a specific electrochemical nanomolarlevelsensor, have facilitated direct detection, enhancing understandingof HNO reactivity and formation.

Enseñar poniendo el precio: el “trabajo” con la teoría en las clases de Noé Jitrik durante la “universidad montonera”; Teaching by setting the price: the “work” with the Theory in the Noé Jitrik’s classes over the “universidad montonera” Gerbaudo, Analía Isabel Este artículo analiza el lugar de la teoría en las clases de Literatura Latinoamericana dictadas por Noé Jitrik durante 1973 y 1974 en la carrera de Letras de la Universidad de Buenos Aires (“teoría” está escrito en singular debido a que hago referencia al constructo general, más allá de las teorías particulares que Jitrik suscribía). Este análisis hace foco en las consecuencias epistemológicas, metodológicas, éticas y políticas que Jitrik atribuía al “trabajo” con la literatura apoyado en el conocimiento de teoría. Estos resultados se ponen en diálogo con otros, a los efectos de contribuir a exhumar el conjunto de las intervenciones realizadas desde la cátedra Literatura Iberoamericana o Literatura y cultura latinoamericanas I en el período (la denominación se modificó apenas iniciado el primer cuatrimestre de 1974). En la demostración retomo algunas de las derivas de estas clases en prácticas de investigación y enseñanza.; This article analyses the place of Theory in the Noé Jitrik’s Latin American Literature classes during 1973 and 1974 in the Letters degree at the University of Buenos Aires (“Theory” is written in singular because I refer to the general concept, beyond the particular theories that Jitrik supported). It focuses on the epistemological, methodological, ethical, and political consequences that Jitrik assigned to the literary analysis based on the theory’s knowledge. These results are confronted with others for the purpose of contributing to the exhumation of the set of actions carried on by the people who had leading the chair of Literatura Iberoamericana or Literatura y cultura latinoamericanas I in the period (the denomination was modified at the beginning of the first term of 1974). In the demonstration I collect some of the consequences of these classes in others research and teaching’s practices.

Efectos de la calidad de los bosques de ribera sobre la diversidad de escarabajos estercoleros (Coleoptera: Scarabaeinae) Guerrero, Sofía Eugenia; Vespa, Natalia Isabel; Gomez Cifuentes, Andres Mauricio Los cambios en el microclima por consecuencia de las alteraciones en la estructura del bosque inciden sobre la diversidad y el funcionamiento de los ecosistemas. En particular, los escarabajos estercoleros (Coleoptera: Scarabaeinae) son muy sensibles a estos cambios por lo que son considerados buenos indicadores biológicos del estado de conservación del ambiente. Los bosques ribereños funcionan como filtros que mitigan el ingreso de contaminantes a los arroyos, en paisajes antropizados, se ven afectados por la conversión del uso de suelo, actividad que produce cambios no solo en las condiciones ambientales, sino que también, perturba la composición de especies y sus roles ecológicos. Los estudios de diversidad resultan de gran interés para aportar información a las estrategias de conservación, así como implementación de prácticas favorables al funcionamiento de estos ambientes. Es por ello, que el objetivo de este trabajo fue evaluar la diversidad de escarabajos estercoleros entre dos franjas de bosques ribereños que difieren en el ancho que establece la ley XVI N.º 105 de la provincia de Misiones-Argentina. El relevamiento se llevó a cabo a lo largo del arroyo Urugua-í. Se establecieron dos transectos de 200m cada uno, en un bosque ripario continuo (BC), dentro de un Área Protegida (Reserva de Vida Silvestre Urugua-i, RVSU) y en un bosque ripario intervenido (BI) fuera de los límites de la Reserva; separados por al menos 1km para asegurar su independencia espacial. En cada sitio de muestreo, se instalaron trampas de caída (pitfall) para colectar escarabajos a través del método de captura viva (liberados luego de su identificación taxonómica). Se evaluó la cobertura vegetal del dosel y la altura de las especies arbóreas mayores o iguales a 10cm de perímetro con el objetivo de caracterizar y comparar la vegetación de cada bosque y así poder relacionarla con la presencia-ausencia de escarabajos. Se registraron 116 individuos en total, correspondientes a siete especies. Dentro del BI se capturaron un total de 40 individuos y cuatro especies. Por otro lado, en el BC se registraron un total de 76 individuos y siete especies. Para el muestreo de vegetación, en el BC se identificaron 11 especies y 28 individuos arbóreos, en comparación con el BI con 8 especies y 15 individuos. Los resultados indican que existe una relación entre el tamaño de las franjas protectoras y la riqueza/abundancia de los escarabajos estercoleros. La implementación de estudios más rigurosos facilitaría la obtención de datos precisos que permitan generar conocimientos superiores sobre la ecología de las especies halladas y su relación con los bosques ribereños, desencadenando en mejores planes de manejo dentro de las AP, con el objetivo de conservar su biodiversidad.

Estos resultados preliminares muestran la importancia de realizar análisis locales de los componentes bioactivos en especies locales para poder identificar y proponer posibles aplicaciones del mismo. Así, los componentes bioactivos de Schinus areira encontrados son promisorios para ser aplicados en líneas de investigación vinculadas a su uso como conservante y/o pesticida.; Schinus areira L., popularly known as "aguaribay, false pepper, pink pepper, molle," is a plant potentially utilized by both past and present human populations for various purposes in the pharmaceutical, health, cosmetic, agricultural, and food industries. This work aims to extract the essential oil from aguaribay collected in San Rafael, Mendoza, and quantify the detected bioactive components. The essential oil was extracted from the leaves through steam distillation and analyzed using gas chromatography coupled with a flame ionization detector (GC/FID). A total of 15 active compounds were identified. Hydrocarbon monoterpenes were the most abundant at 83.07%, with limonene being the most representative (30.78%), followed by sesquiterpene hydrocarbons (5.21%) with δ-cadinene as the main component. These preliminary results highlight the importance of conducting local analyses of bioactive components in local species to identify and propose possible applications. Thus, the bioactive components found in Schinus areira are promising for application in research lines related to its use as a preservative and/or pesticide.

Development of gluten-free and gum-free rice bread: influence of ingredients, hydration and processing time on bread quality González, Luciana Carla; Contigiani, Eunice Valentina; Tolaba, Marcela Patricia Gluten-free and gum-free breads were developed, with thefocus on the impact of raw materials (rice grain or flour) and processingconditions (pre-hydration and mixing time). The evaluation of bread qualityprimarily involved after the measurement of specific volume (BV), alveolar area(AA), and crumb hardness both before and storage. BV varied within 1.99?2.97ml/g for rice bread and 2.14?2.26 ml/g for flour bread, with control(containing xanthan gum) values of 2.65 and 3.11 ml/g for rice and flour bread,respectively. An increase in AA was observed (rice: 0.5?1.9 mm2 andflour: 0.76?2.0 mm2) compared to controls with gum (rice: 0.36 andflour: 1.41 mm2). Pre-hydration of ingredients and reduced mixing timeimproved bread quality: volume of bread from hydrated rice and 4 min of mixingtime was comparable to that of gum control. Although the aging process,measured by hardness, was faster than in gum-containing bread, process conditionswere identified that delayed aging. This information is essential and valuablefor future research.

A novel and efficient Apple latent spherical virus-based gene silencing method for functional genomic studies in Chenopodium quinoa Melgar, Alejandra Estefania; Palacios, María Belén; Martínez Tosar, Leandro Julián; Zelada, Alicia Mercedes Quinoa (Chenopodium quinoa Willd.), with its resilience in harsh environments and excellent nutritional value, has become crucial for global food security. Despite recent progress in genomic research, the inability to perform functional studies in quinoa due to the absence of transformation techniques remains a significant obstacle. In this work, we present the development of a novel Apple Latent Spherical Virus (ALSV)-mediated virus-induced gene silencing (VIGS) protocol that will allow to perform functional genomics studies in quinoa in a fast and simple way. The method was fine-tuned using ALSV plasmids that carry partial gene sequences of phytoene desaturase (PDS) from Nicotiana benthamiana and quinoa. The developed technique involves an initial inoculation in Nicotiana plants through agroinfiltration with Agrobacterium tumefaciens cultures carrying the different viral constructs. Viral extracts were prepared using local or systemic leaves, which were then used as inoculum to infect quinoa leaves through mechanical damage. The method was successfully tested in two contrasting quinoa varieties, although some differences were observed in infection phenotype and viral susceptibility. The effect of insertion sequence size in the viral vectors was also analyzed, resulting in differences in bleaching or chlorosis phenotype and impact on plant growth. The presence of the virus in inoculated plants was confirmed, and the reduction in PDS gene expression in silenced plants was verified. Because quinoa lacks stable transformation protocols, limiting heterologous expression assays, our ALSV-based VIGS protocol is very attractive for loss-of-function gene studies.

Platón, maestro de Schopenhauer: Las enseñanzas de la Teoría de las Ideas en la composición de un único pensamiento (ein einziger Gedanke); Plato, teacher of schopenhauer: the teachings of platonic philosophy in the deployment of a unique thought (ein einziger Gedanke) Gonzalez Rios, Hector Jose El artículo propone indagar el único pensamiento al que Schopenhauer ciñe su filosofía a través del estudio de la explícita recepción y efecto de la filosofía de Platón en su génesis y desarrollo. Con frecuencia, los estudios que se abocan a las fuentes de este pensamiento circunscriben la presencia platónica al examen de su estética (presentada, entre otros, en el Libro Tercero de El mundo como voluntad y representación (1819), en las Lecciones sobre la metafísica de lo bello (1820) y en muchos pasajes de su invaluable legado manuscrito). Sin embargo, resulta lícito explorar también su presencia en la dimensión ética de aquel único pensamiento, que Schopenhauer despliega en el Libro Cuarto de su opus magnum. De este modo la figura de Platón quedará ligada no sólo a la del genio sino también a la de aquellos que han postulado la negación de la voluntad llevando así la filosofía a su propio límite.; The article aims to explore the unique thought (ein einziger Gedanke) to which Schopenhauer refers his philosophy through the study of the explicit reception and effect of Plato in its genesis and development. Frequently, studies of sources circumscribe the Platonic presence in his philosophy to the consideration of his aesthetics, presented in Book Three of The World as Will and Representation (1819) and later in the Lessons on the Metaphysics of the Beautiful (1820) and in his invaluable manuscript legacy. However, it is also permissible to explore his presence in the ethical dimension of that unique thought, which Schopenhauer unfolds in Book Four of his opus magnum and. In this way the figure of Plato will be linked not only to that of genius but also to that of those who have postulated the negation of the will, thus bringing philosophy to its limit.

Necesidades, derechos y lenguajes: Un estudio etnográfico sobre habitar y construcción de ciudadanía en Buenos Aires; Needs, rights and languages: An ethnographic study about inhabiting and making of citizenship in Buenos Aires Thomasz, Ana Gretel; Boroccioni, Luciana Este artículo entrecruza las problemáticas del habitar y el derecho a la vivienda con la de la construcción de ciudadanía, a las que explora desde una perspectiva antropológica. Retoma el trabajo etnográfico desarrollado entre 2015 y 2020 con los pobladores de un edificio recuperado de la Ciudad de Buenos Aires, quienes enfrentan un juicio de desalojo. Se vale del concepto de habitar de Giglia (2012) y aportes de Holston (2008) y Wanderley (2009), que examinan la cuestión del acceso a derechos identificando los lenguajes y las modalidades de acción a los que apelan los sujetos para materializarlos. Se expresa aquí que si durante el período inicial predominó la “lógica de la necesidad” y un accionar orientado a tornar habitable un inmueble abandonado, posteriormente emergió entre los pobladores el “lenguaje de los derechos”. Contra lo que sugiere la concepción de ciudadanía liberal, concluye que la auto-percepción de sí mismos como “sujetos de derecho” no es algo dado sino un proceso que se construye a partir de los vínculos horizontales que los sujetos establecen entre sí y con organizaciones sociales, y las relaciones verticales y conflictivas entabladas con el Estado en forma mayormente colectiva.; This article links the issues of the inhabit and housing rights with that of the making of citizenship, which are explored from an anthropological perspective. It is based on the ethographic work developed between 2015-2020 with the inhabitants of a squattered building from the City of Buenos Aires, who face an eviction judgment. It takes up the concept of inhabit introduced by Giglia (2012) and contributions of Holston (2008) and Wanderley (2009) that explore the issue of the access to rights identifying the different languages and modalities of action deployed by the subjects in order to get them. It is argued here that if it prevailed initially the “logic of the necessity” and an action aimed to rend habitable an abandoned property, the “language of rights” emerge later among the inhabitants. In contrast to what the liberal conception suggests, it is concluded that the self-perception of themselves as “subjects of rights” is not something given but a process that is built from the “logic of necessity”, the horizontal links that the subjects establish among themselves and with social organizations, and the vertical relationships established with the State in a mostly collective way.

¿Era Platón un spinozista?: Algunas ideas sobre la recepción de Platón en Alemania a finales del siglo XVIII; Was Plato a spinozist?: Some thoughts on the reception of Plato in Germany at the end of the 18th century Sole, Maria Jimena La propuesta de este artículo es abordar la recepción de Platón en el contexto de la célebre Polémica del panteísmo (Pantheismusstreit) aplicando las herramientas conceptuales y metodológicas obtenidas a partir de una exploración colectiva iniciada hace ya algunos años y todavía en curso, que llamamos caminos cruzados. En el transcurso de esta polémica, desencadenada a comienzos de la década de 1780 por F. H. Jacobi al revelar que el gran hombre de la ilustración alemana, G. E. Lessing, le había confesado poco antes de morir su secreto spinozismo, reaparece una tesis ya defendida a finales del siglo anterior por P. Bayle y G. Wachter, según la cual Spinoza y Platón se nutrieron de la misma tradición y adhieren, en el fondo, a una misma doctrina. Apelando a la perspectiva de los caminos cruzados, planteo la pregunta (imposible desde las perspectivas historiográficas habituales) acerca del spinozismo de Platón para reconstruir el vínculo que Jacobi ve entre ellos y revelar así aspectos que, en el estudio de la recepción, suelen permanecer ocultos, como el hecho de que una misma tesis puede tener un significado completamente distinto en diferentes autores y el rol fundamental que tiene la construcción de un enemigo para darle forma y justificación a la posición propia.; This article proposes to address the reception of Plato in the context of the famous Pantheism debate (Pantheismusstreit) by applying the conceptual and methodological tools obtained from a collective exploration begun some years ago and still ongoing, which we call caminos cruzados (crossed paths). In the course of this polemic, triggered in the early 1780s by F. H. Jacobi when he revealed that the great man of the German Enlightenment, G. E. Lessing, had confessed to him shortly before his death his secret Spinozism, a thesis already defended at the end of the previous century by P. Bayle and G. Wachter reappears, according to which Spinoza and Plato were nourished by the same tradition and subscribe, at their core, to the same doctrine. Using the perspective of crossed paths, I pose the question (impossible from the usual historiographical perspectives) about Plato's Spinozism in order to reconstruct the link that Jacobi sees between them and thus reveal aspects that, in the study of reception, often remain hidden, such as the fact that the same thesis can have a completely different meaning in different authors and the fundamental role that the construction of an enemy plays in shaping and justifying one's own position.

VVVX survey dusts off a new intermediate-age star cluster in the Milky Way disk Garro, Elisa; Minniti, Dante; Alonso García, Javier; Fernández Trincado, José; Gómez, Matías; Palma, Tali; Saito, Roberto; Obasi, Casmir Context. In the last decade, many new star clusters have been discovered in heavily obscured regions of the Milky Way bulge and disk. Aims. Our primary long-term objective is to seek out additional star clusters in the poorly studied regions of the Milky Way, where detections pose significant challenges. The aim of this pursuit is to finalize the Milky Way’s globular and open cluster system census and to gain a comprehensive understanding of both the formation and evolution of these systems and our Galaxy as a whole. Methods. We report the discovery of a new star cluster, named Garro 03. We investigated this new target using a combination of near-infrared and optical databases. We employed the VISTA Variables in the Via Láctea Survey and Two Micron All Sky Survey data in the near-infrared, and the Gaia Data Release 3 and the DECam Plane Survey datasets in the optical passband. We constructed density maps and vector proper motion diagrams in order to highlight our target. We performed a photometrical analysis in order to derive its main physical parameters. Results. Garro 03 is located at equatorial coordinates RA = 14:01:29.3 and Dec = −65:30:57.0. From our photometric analysis we find that this cluster is not heavily affected by extinction with AKs = 0.25 ± 0.04 mag and AG = 1.54 ± 0.02 mag. It is located at heliocentric distance of 14.1 ± 0.5 kpc, which places Garro 03 at 10.6 kpc from the Galactic centre and Z = −0.89 kpc below the Galactic plane. We also calculated the mean cluster proper motion of (μα*,μδ)=(−4.57 ± 0.29, −1.36 ± 0.27) mas yr−1. We derived an age of 3 Gyr and metallicity [Fe/H] = −0.5 ± 0.2 by the isochrone-fitting method, employing the PARSEC models. The total luminosity was derived in the Ks and V bands, finding MKs = −6.32 ± 1.10 mag and MV = −4.06 mag. Finally, the core and tidal radii were measured constructing the Garro 03 radial density profile and fitting the King model. We obtained rc = 3.07 ± 0.98 pc and rt = 19.36 ± 15.96 pc, respectively. Conclusions. We photometrically confirm the cluster nature for Garro 03, located in the Galactic disk. It is a distant, low-luminosity, metal-rich star cluster of intermediate age. We also searched for possible signatures (streams or bridges) between Garro 03 and Garro 01, but we exclude a companionship with the present analysis. We need spectroscopic data to classify it as an old open cluster or a young globular cluster, and to understand its origin.

¿Quiénes conocen los canales de ayuda frente a situaciones de violencia en CABA?: Una aproximación a partir de datos de encuesta Safranoff, Ana A partir del análisis de la Encuesta sobre la Situación de las Mujeres en la Ciudad de Buenos Aires (2018), el artículo busca explorar qué características de las mujeres están asociadas con la probabilidad de conocer (o no) los distintos canales de ayuda disponibles frente a situaciones de violencia. Los resultados muestran que, en términos generales, las mujeres que nacieron fuera de Argentina y/o tienen menores niveles educativos son menos proclives a conocer los canales de ayuda, lo cual las sitúa en una situación más desfavorable. Asimismo, las mujeres más jóvenes y quienes tienen hijos/as tienden a conocer más los dispositivos y servicios existentes. Estos hallazgos muestran la necesidad de diseñar políticas focalizadas para segmentos específicos de mujeres tendientes a favorecer la difusión de los distintos dispositivos disponibles, de modo tal de que puedan recurrir a ellos en caso de requerirlos, con vistas a lograr una mayor efectividad y eficacia en los modos de diseñar y comunicar las políticas públicas vigentes.; Based on the analysis of the Encuesta sobre la Situación de las Mujeres en la Ciudad de Buenos Aires (2018), the article aims to explore which characteristics of women are associated with the likelihood of knowing (or not) the various available channels of assistance in situations of violence. The results show that, in general terms, women born outside of Argentina and/or with lower educational levels are less likely to be aware of the available channels of assistance, placing them in a more unfavorable situation. Additionally, younger women and those with children tend to be more aware of existing devices and services. These findings highlight the need to design targeted policies for specific segments of women aimed at promoting the dissemination of the various available devices, so that they can resort to them if needed, aiming to achieve greater effectiveness and efficiency in the ways of designing and communicating current public policies.

Relación entre el consumo moderado de alcohol, polimorfismos genéticos y el peso corporal en una muestra de la población de la ciudad de Puerto Madryn, Argentina; Relationship between moderate alcohol consumption, genetic polymorphisms and body weight in a population sample of the city of Puerto Madryn, Argentina Perez, Luis Orlando; Ruderman, Anahí; Useglio, Mariana; Ramallo, Virginia; Paschetta, Carolina Andrea; de Azevedo, Soledad; Navarro, Jose Pablo; Morales, Arturo Leonardo; Trujillo Jiménez, Magda Alexandra; Pazos, Bruno Alfredo; Teodoroff, Tamara Alejandra; Gonzalez-Jose, Rolando Introducción. La relación entre la obesidad y el consumo de alcohol es un tema de gran interés para la salud pública. Las bebidas alcohólicas aportan calorías adicionales a la dieta, lo que podría ser un factor relevante en el riesgo de sobrepeso. Sin embargo, su asociación con la ganancia de peso es controversial y está influenciada por múltiples factores.Objetivo. Analizar la relación entre la ingesta moderada de alcohol y el índice de masa corporal, tomando en consideración las variables que pueden influir en dicha relación.Materiales y métodos. La muestra estuvo constituida por 155 personas de la ciudad de Puerto Madryn, Argentina. Cada participante completó un cuestionario sobre salud, estilo de vida, factores demográficos y socioeconómicos. Se tomaron medidas antropométricas y genotipificaron polimorfismos de 18 genes relacionados al metabolismo de alcohol. Resultados. Se encontró que el consumo de alcohol moderado está asociado a un índice de masa corporal más bajo, particularmente en el sexo femenino. Un aumento de 14 gramos de alcohol estuvo asociado a un riesgo de 0,68 para la obesidad y 0,71 para el sobrepeso. La variante T del marcador rs4646543 (ALDH1A1), un gen involucrado en el metabolismo del alcohol y en la adipogénesis, estuvo asociado con una mayor frecuencia de consumo de bebidas alcohólicas.Conclusión. Los hallazgos del presente trabajo sugieren que el consumo moderado de alcohol no contribuye significativamente al peso corporal en la muestra estudiada. Además, la asociación con ciertas variantes genéticas, como las del gen ALDH1A1, podrían dar una explicación biológica a la relación inversa observada entre el peso y el consumo de alcohol.; Introduction.The relationship between obesity and alcohol consumption is a topic of significant interest for public health. Alcoholic beverages contribute additional calories to the diet, which could be a relevant factor to the overweight risk. However, its association with weight gain is controversial and influenced by multiple factors.Objective.To analyze the relationship between moderate alcohol intake and body mass index, considering the variables that may influence this relationship.Materials and methods.The sample consisted of 155 individuals from the city of Puerto Madryn, Argentina. Each participant completed a questionnaire on health, lifestyle, demographic, and socioeconomic factors. Anthropometric measurements were taken, and polymorphisms of 18 genes related to alcohol metabolism were genotyped.Results.We found that moderate alcohol consumption is associated with a lower body mass index, particularly in females. An increase of 14 grams of alcohol was associated with a risk of 0.68 for obesity and 0.71 for overweight. The T variant of the marker rs4646543(ALDH1A1), a gene involved in alcohol metabolism and adipogenesis, was associated with a higher frequency of alcohol consumption.Conclusion.The findings of this study suggest that moderate alcohol consumption does not significantly contribute to body weight in the studied sample. Furthermore, the association with certain genetic variants, such as those of the ALDH1A1 gene, may provide a biological explanation for the inverse relationship observed between weight and alcohol consumption.

Primera confirmación de la existencia de minería prehispánica en la Puna Norte: resultados de las investigaciones en Timón Cruz 2 (Jujuy, Argentina); First confirmation of the existence of pre-hispanic mining in the Northern Puna: Results of investigations in Yimón Cruz 2 (Jujuy, Argentina) Angiorama, Carlos Ignacio; Giusta, Marco Nicolás; Becerra, María Florencia; Perez Pieroni, María Josefina; Torres Vega, Lucrecia Marina Raquel En este trabajo presentamos los primeros resultados de nuestras investigaciones sobre la minería de tiempos prehispánicos en Timón Cruz 2, un sitio arqueológico de la Puna de Jujuy (Argentina). Los avances dan cuenta de una instalación dedicada a la minería aurífera desde al menos el siglo X de nuestra era, y que continuó hasta tiempos coloniales inclusive. La relevancia de la información presentada radica en que se trata de las primeras evidencias fehacientes de actividades mineras prehispánicas en la región, con el registro de herramientas líticas vinculadas al procesamiento de minerales auríferos en contextos fechados y localizados en cercanías de pozos, trincheras, socavones y desmontes, producto de la explotación de oro en veta y en depósitos secundarios.; This paper presents the first results of our research on pre-Columbian mining in Timón Cruz 2, an archaeo- logical site in the Jujuy puna (Argen- tina). These findings shed light on a settlement dedicated to gold mining which dates to at least the 10th century AD and persisted even into colonial times. This research holds significant importance as this site shows the first tangible evidence of pre-Hispan- ic mining activities in the region, with the recording of lithic tools associated with the processing of gold-bearing minerals in dated contexts located near shafts, trenches, adits, and spoil heaps, product of primary gold and secondary deposits exploitation.

Individualism, collectivism, and emotion regulation: A cross-cultural examination among young adults from seven countries Klein, Neelamberi D.; Bravo, Adrian J.; Conway, Christopher C.; Keough, Matthew T.; Pilatti, Angelina; Mezquita, Laura; Henson, James M.; Hogarth, Lee; Ibáñez, Manuel I.; Kaminer, Debra; Ortet, Generós; Pearson, Matthew R.; Prince, Mark A.; Read, Jennifer; Roozen, Hendrik G.; Ruiz, Paul Individualism and collectivism are dimensions of cultural variation thought to shape differences in emotion regulation tendencies, yet research to date has examined these cultural dimensions as country-level features, emphasizing variability across nations. The present study takes the approach of examining cultural differences within nations as predictors of emotion regulation strategies, shifting the perspective instead to individual differences. This present study aimed to address how individual endorsement of individualism-collectivism (i.e. prioritizing individual versus group goals) and vertical-horizontal attitudes (preference for hierarchy versus equality) are associated with use of emotion regulation strategies (i.e., reappraisal and suppression) among college students from seven countries (n=5,900; female=70.80%). Overall, we found that individual differences in individualism-collectivism and vertical-horizontal attitudes had strong connections with young adults’ emotion regulation styles. Results of our multivariate (i.e., all variables were simultaneously examined) regression model revealed: a) higher endorsement of horizontal individualism and horizontal collectivism were associated with higher use of reappraisal strategies; b) higher endorsement of horizontal individualism and vertical collectivism were associated with higher use of suppression strategies; while higher endorsement of horizontal collectivism was associated with lower use of suppression strategies. A multi-group model supported the generalizability of these associations across countries. These findings demonstrate the value of approaching cultural differences in emotion regulation from an individual differences framework, and not assuming country-level differences are representative of individuals’ affective experiences. Further work is needed examining models within-country to examine cultural variation in individualism vs collectivism compared to country-level norms.

Aportes del análisis cerámico sobre el uso del espacio en el Puesto Pastoril Pichanal 4 (Sierra del Cajón, provincia de Catamarca) Rampa, Daniel Alfredo En este trabajo se estudia una muestra ampliada de la cerámica superficial del sitio pastoril Pichanal 4 (Sierra del Cajón, Pcia. de Catamarca). Con el fin de evaluar la distribución cerámica existente dentro de los recintos que componen Pichanal 4, se confeccionaron dos dendrogramas que analizan abundancia cerámica, y los estilos y tratamientos presentes en la misma. Los resultados estadísticos confirman que la distribución de la cerámica superficial en Pichanal 4 no fue provocada por el azar. Se corrobora entonces la singularidad de este puesto pastoril, y se plantea una utilización más compleja de sus espacios. Pichanal 4 presenta una mayor extensión, complejidad espacial, abundancia cerámica y variabilidad estilística, que los otros sitios pastoriles de la región, y es posible que, en ciertos momentos del año, algunos de sus grandes corrales concentraran a los grupos de pastores y el ganado disperso en los diferentes puestos de altura de la Sierra del Cajón.

Ohmic baking of gluten free sponge cake: Analysis of technological and quality characteristics Mattioli, Nicolás Gabriel; Olivera, Daniela Flavia; Salvadori, Viviana Olga; Marra, Francesco; Goñi, Sandro Mauricio The demand of gluten-free bakery products is worldwide increasing. Simultaneously, ohmic heating is an alternative heating technology that still deserves further research and development. Therefore, the aim of this work was assessing different technological and quality characteristics of gluten free sponge cake baked by ohmic heating. A custom ohmic system was designed and built and different electric field strengths (1500, 2000 and 2500 V/m) were tested. Conventional baking was performed for comparison purposes. The conventional baking time was 24 minutes, whilst the ohmic heating time ranged from 3.51 minutes at 2500 V/m to 7.93 minutes at 1500 V/m. The ohmic system achieved significantly higher energy efficiencies, reaching nearly 60%, compared to only 4.1% for conventional baking. Additionally, specific energy consumption was significantly lower for ohmic heating. Weight loss was higher for ohmically processed samples, showing larger pores in their inner spongy structure. Ohmic heating resulted in a larger volume expansion and a cake with lower density. The remaining quality characteristics, such as color, hardness, cohesiveness, and elasticity, were not significantly different. Results demonstrated that ohmic heating is a suitable technology for baking gluten-free sponge cakes and that it is a promising technology for fast industrial baking of such products.
