Method: A total of 234 adolescents aged 12-16 years (M = 14.48, SD = 1.09) selected for the Youth Olympic Games -Buenos Aires 2018- participated in the study, who answered questionnaires assessing the variables of interest. Results: Males perceived higher levels of engagement than females, and females perceived higher autonomy support from the mother. Coaches’ autonomy support had greater predictive power on males’ engagement and females’ intentions to drop-out sport. In both genders, the effect of coach autonomy support was greater than parents. Conclusions: These results show the importance of significant others in sport participation and contribute to the knowledge of factors that may foster positive development in high-performance adolescence athletes.

Haplotypes traceability and genetic variability of the breeding population of pacu (Piaractus mesopotamicus) revealed by mitochondrial DNA de Freitas, Milena V.; Ariede, Raquel B.; Hata, Milene E.; Mastrochirico Filho, Vito A.; del Pazo, Felipe; Villanova, Gabriela Vanina; Mendonça, Fernando F.; Foresti, Fábio Porto; Hashimoto, Diogo T. The main objective of this study was to estimate the genetic diversity levels and haplotype traceability in pacu Piaractus mesopotamicus from the breeding program located in Brazil by analyses of the mitochondrial DNA control region (mtDNA). Moreover, broodstocks from eight commercial fish farms were used for comparative evaluation, four from Brazil (Br1-Br4) and four from Argentina (Ar1-Ar4). The descriptive results revealed 47 polymorphic sites and 51 mutations, which evidenced 34 haplotypes. Ten haplotypes were shared among fish farms and 24 were exclusive. The nucleotide diversity (π) ranged from 0.00031 to 0.01462 and haplotype diversity (Hd) from 0.125 to 0.868. The analysis of molecular variance (AMOVA) indicated high structure present in the analyzed stocks (FST = 0.13356 and ФST = 0.52707). The genetic diversity was high in most of the commercial broodstocks, especially those from Brazil. We observed seven haplotypes in the genetic breeding population, of which four were exclusive and three shared among the commercial fish farms. The genetic diversity was moderate (π = 0.00265 and Hd = 0.424) and considered appropriated for this breeding population of pacu. Our results provide support for the genetic diversity maintenance and mtDNA traceability of pacu commercial broodstocks.

Sex chromosomes in the Vizcacheras’ White-lipped frog, Leptodactylus bufonius (Anura, Leptodactylidae) Schneider, Rosio Gabriela; Ferro, Juan Martín; Reinko, Ivana Noelia; Boeris, Juan Martín; Cardozo, Dario Elbio; Baldo, Juan Diego Cytogenetic analyses were performed on specimens of Leptodactylus bufonius from different localities in Argentina. Mitotic chromosomes were studied with Giemsa and differential staining techniques (Ag-NOR, C-banding, and CMA3 /DAPI) and fl uorescence in situ hybridization with the 18S DNAr probe. All specimens showed karyotypes with 2n = 2x = 22 and FN = 44. Secondary constrictions were present in the long arm of chromosome pair 8, coincident with Ag-NOR and hybridization signals of the 18S DNAr probe. The C-banding technique evidenced an important amount of heterochromatin with a sex-linked pericentromeric band in the short arm of chromosome pair 4. This heterochromatic band was heteromorphic in males but present in both homologues of females, and it was CMA3 positive (DAPI negative) at fl uorescence staining. The occurrence of heteromorphic XY sex chromosomes in L. bufonius is the second known case in Leptodactylus and the fi fth within the speciose family Leptodactylidae.

AISYF: first national, prospective, multicenter study of young patients with stroke in Argentina; AISYF: primer estudio nacional, prospectivo y multicéntrico de pacientes jóvenes con ataque cerebral en Argentina Bonardo, Pablo; Leon Cejas, Luciana; Mazziotti, Julieta; Zinnerman, Alberto; Fernandez Pardal, Manuel; Martinez, Alejandra; Riccio, Patricia; Ameriso, Sebastian Francisco; Bendersky, Eduardo Daniel; Nofal, Pedro; Cairola, Patricia; Jure, Lorena; Sotelo, Andrea; Casas Parera, Ignacio Faustino; Sánchez Luceros, Analía Gabriela; Sposato, Luciano A.; Reisin, Ricardo C. Aproximadamente un 15% de todos los ataques cerebrovasculares afectan a pacientes jóvenes y su incidencia estaría en aumento. Existe escasa información sobre el ataque cerebral en esta población tanto en nuestro país como en Latinoamérica. El objetivo de nuestro estudio fue evaluar las características clínicas y los factores de riesgo de los adultos jóvenes con ictus en Argentina. Realizamos un estudio prospectivo y multicéntrico en adultos jóvenes (18-55 años) en Argentina, que presentaron un evento cerebrovascular dentro de los 180 días previos. Los subtipos de ictus se clasificaron según los criterios de TOAST. Se incluyeron un total de 311 pacientes (hombres 53.9%, edad media: 43,3 años). Los ataques cerebrovasculares isquémicos ocurrieron en el 91.8% (infartos cerebrales 82.6%, ataque isquémico transitorio 9.2%) y los eventos hemorrágicos correspondieron al 8.2%. Los factores de riesgo vascular más frecuentes (incluyendo los eventos isquémicos y hemorrágicos) fueron: hipertensión 120 (41%), tabaquismo 92 (31.4%), dislipidemia 81 (27.6%) y sobrepeso/obesidad: 74 (25.3%). Los subtipos de ictus isquémicos fueron: arteriopatía de gran vaso 12.3%, cardioembolismo 7.5%, oclusión de pequeña arteria 11.5%, otra etiología definida 27.1% y etiología indeterminada 41.6%. Los factores de riesgo vascular son muy frecuentes en los adultos jóvenes con ictus. Nuestros hallazgos subrayan que se requieren estrategias urgentes para la prevención primaria y secundaria del ictus en este grupo particular de pacientes en nuestro país.; Up to 15% of all strokes affect young patients and the incidence of ischemic stroke in this population is rising. Nevertheless, there is limited information of cerebrovascular events in this population both in our country and in Latin America. The aim of our study was to evaluate the clinical characteristics and risk factors of young adults with stroke in Argentina. This is a prospective, multicenter study of stroke in young adults (18 - 55 years) in Argentina. Patients presenting with a cerebrovascular event within 180 days were included. Stroke subtypes were classified according to TOAST criteria. A total number of 311 patients were enrolled (men 53.9%, mean age: 43.3 years). Ischemic strokes occurred in 91.8% (brain infarcts 82.6%, transient ischemic attack 9.2%) and hemorrhagic strokes in 8.2%. The most frequent vascular risk factors (including ischemic and hemorrhagic strokes) were: hypertension 120 (41%), smoking 92 (31.4%), dyslipidemia 81 (27.6%) and, overweight/obesity: 74 (25.3%). Stroke subtypes were: large artery disease 12.3%, cardioembolism 7.5%, small artery occlusion 11.5%, other defined etiology 27.1%, and undetermined etiology 41.6%. Our study demonstrates that vascular risk factors are very frequent in young adults with stroke. Our findings underline that urgent strategies are required for primary and secondary stroke prevention in this group of patients.

Familia revolucionaria e infancias: El testimonio como desplazamiento en la casa de los conejos e infancia clandestina; Revolutionary family’ and childhoods: The testimony as displacement in la casa de los conejos and infancia clandestina Argañaraz, María Eugenia Este trabajo se centra en la mirada que los niños, durante la última dictadura militar argentina, conformaron con respecto a sus madres militantes y miembros de ‘familias revolucionarias o militantes’ de Montoneros. Nos hemos focalizado en la novela La casa de los conejos (2008) de Laura Alcoba y en el film Infancia clandestina (2012) de Benjamín Ávila. Se problematizan comparativamente ambas obras desde los posicionamientos de mujeres dentro de la militancia organizativa (Oberti, 2015) con respecto a la centralidad que ocuparon en relación con sus parejas. La mirada de los niños a la que referimos encuentra vínculos con transmisiones que aluden a conformaciones de la propia subjetividad (Kaufman, 2006) en una memoria familiar y en la conformación de trabajos de la memoria (Jelin, 2002) que las voces narrativas de esos hijos/as llevan adelante con el objetivo de dar testimonio. Finalmente, el trabajo de Teresa Basile (2019, 2020) es significativo para dar cuenta acerca de los tipos de infancias que estos niños desarrollan, para dar lugar a lo que se identifica como Segunda Generación de HIJOS. Con el fin de referir a las miradas de los niños, se han tenido en cuenta las formas narrativas en que las obras expresan la crianza en medio de los modos de maternar en contextos de violencia extrema. Ambas piezas aluden a prácticas culturales y testimoniales. Además, en la novela y en el film aparecen infancias con carácter fronterizo, en el sentido de que los niños crecen y dan testimonio de esa dimensión política que recuerdan y construyen a medida que el relato avanza. Todo ello dentro de núcleos familiares militantes que habilitan y habilitaron la figura del infante no solo como testigo sino también como partícipe de la historia argentina.; This work focuses on the view that children, during the last Argentine military dictatorship, formed with respect to their militant mothers, members of ´revolutionary or militant families´ of Montoneros. In this opportunity, our analysis will focus on the novel La casa de los conejos (2008), by Laura Alcoba, and the film Infancia clandestina (2012), by Benjamín Ávila. Our analysis will problematize comparatively both works, exploring the relations between the positions that these women occupy in the organized militancy (Oberti, 2015) and those that they occupy in their couple life. The children's gaze to which we refer finds links with transmissions that allude to conformations of subjectivity itself (Kaufman, 2006) in a family memory and in the conformation of memory works (Jelin, 2002) that the narrative voices that these children carry on with the objective of giving testimony. Finally, the work of Teresa Basile (2019, 2020) will help us to account the types of childhoods that these children develop, leading to what is identified as the Second Generation of CHILDREN. In order to refer to the children’s gaze, we have taken into account the narrative forms in which the works represent the upbringing and mothering in contexts of extreme violence. Both works refer to cultural and testimonial practices. In the novel and in the film, childhoods appear with a border character, in the sense that children grow up and bear witness to that political dimension that they remember and build as the story progresses. All this within militant family nuclei that enable and empower the figure of the infant not only as a witness but as a participant in Argentine history.

Interdisciplinary research networks and science-policy-society interactions in the Uruguay River Basin Saguier, Marcelo; Gerlak, Andrea K.; Villar, Pilar Carolina; Baigún, Claudio Rafael M.; Venturini, Virginia; Lara, Albina; Dos Santos, Marco Aurelio The Uruguay River Basin (URB) that extends along Argentina, Brazil and Uruguay has been the hub of increasing pressures caused by the expansion of industrial agriculture, forestry and infrastructure projects in hydroenergy and transportation. There are growing concerns that the fragmented institutional framework is inadequate to address the growing challenges. Interdisciplinary research networks can contribute to creating perspectives of the basin that are policy and governance relevant. In this paper, we set out to interrogate the potential scope of interdisciplinary research networks (IRNs) for the advancement of basin governance framework for the URB. We envision IRNs as knowledge actors that can open up opportunities to mediate and connect basin actors across different spaces - academic, policy, technical-administrative and social. We highlight a series of pathways to advance networks actions in creating opportunities to fill the gaps of transboundary basin governance, and acknowledge the challenges associated with doing this work in the URB and other basins around the world.

San Andres de Teixido: Corpus Christi en un santuario de montaña en el norte de Galicia; San Andres de Teixido: Corpus Christi in a mountain sanctuary in northern Galicia Ceruti, Maria Constanza Construido en la Sierra da Capelada, el santuario de San Andrés de Teixido es un importante centro de peregrinaje en el norte de España, ornado con leyendas de almas que se "condenaron" por no haberlo visitado en vida. El complejo ceremonial se encuentra emplazado entre los acantilados más altos de Europa, los cuales son transitados a través de senderos de peregrinaje señalados por mojones y cruceiros. La autora efectuó el acercamiento a pie al santuario, recorriendo las alturas de los acantilados y sus fabulosas vistas panorámicas. Visitó una fuente de agua sagrada y documentó los depósitos de exvotos en una cripta exterior subterránea, así como las leyendas populares entretejidas en torno a San Andrés de Teixido y a la diversidad de miniaturas de pan que los peregrinos llevan como reliquias a sus hogares. Asimismo, compartió la procesión de Corpus Christi, precedida por la celebración eucarística al interior de la iglesia, en la que participaron cófrades, devotos y gaiteros. La tradición de peregrinar con fines religiosos reconoce una antigüedad milenaria en el mundo gallego y se materializa tanto en peregrinajes individuales como en procesiones colectivas y romerías. En las consideraciones del trabajo, se analiza el fenómeno del peregrinaje a San Andrés de Teixido en el contexto de la religiosidad popular gallega, teniendo en cuenta las antiguas prácticas monásticas en las fragas boscosas que flanquean al río Eume y los modernos ritos solsticiales, que incluyen las famosas hogueras de San Juan, en playas sobre el estuario de Pontedeume.; Built in the Sierra da Capelada, the shrine of San Andrés de Teixido is an important pilgrimage center in the north of Spain, adorned with legends of souls that were "condemned" for not having visited it while they were alive. The ceremonial complex is located between the highest cliffs in Europe, which are traveled through pilgrimage trails marked by milestones. The author made the approach on foot to the San Andrés shrine, crossing the heights of the cliffs and enjoying their fabulous panoramic views. She visited a source of sacred water and documented the votive offerings in the outer crypt of the sanctuary, as well as the popular legends woven around the diversity of miniature figurines made of bread, that pilgrims carry as relics to their homes. She participated in the Corpus Christi procession preceded by the Eucharistic celebration inside the church of San Andrés, together with confreres, devotees and bagpipers participated. The tradition of pilgrimage for religious purposes recognizes a millenary antiquity in the Galician world and is materialized both, in individual pilgrimages and in collective processions. In the considerations of the paper, the phenomenon of the pilgrimage to San Andrés de Teixido is analyzed in the context of the popular religiosity of northern Galicia, taking into account the ancient monastic practices in the wooded fragas that flank the Eume river and the modern summer solstice rites, which include the famous San Juan bonfires, on beaches on the Pontedeume estuary.

Amphibians and reptiles as palaeonvironmental proxies during the Late Pleistocene (MIS3): The case of Stratigraphic Unit V of El Salt, Alcoi, Spain Marquina Blasco, Rafael; Fagoaga, Ana; Crespo Roures, Vicente Daniel; Bailon, Salvador; Mallol, Carolina; Hernández, Cristo M.; Galván, Bertila; Ruiz Sánchez, Francisco Javier The locality of El Salt (Alcoi, Spain) is a key site for understanding the extirpation of Neanderthals in the eastern part of Iberia. In this paper, we analyse an assemblage of amphibians and reptiles from Stratigraphic Unit V (45.2 ± 3.4 ka to 44.7 ± 3.4 ka), which corresponds to one of the last regional records of Neanderthals, to improve knowledge of the palaeoecology and palaeoclimate of this event. The assemblage comprises three anurans (Pelodytes sp., Alytes obstetricans, and Epidalea calamita), two lizards (Lacertidae indet. and Chalcides bedriagai), and five snakes (Colubridae indet., Coronella sp., Coronella sp./Zamenis sp., Natrix maura, and Vipera latastei). Palaeoclimatic reconstruction, based on the Mutual Ecogeographic Range method, indicates that climate was cooler and slightly wetter climate than the present day climate of the Alcoi area. Applying the Habitat Weighting Method, we infer that the area surrounding El Salt was dominated by open dry regions, alternating with rocky areas with scarce scrubs and forest patches that would have developed under mesomediterranean conditions. These results are not entirely consistent with those obtained with other proxies (charcoal and small mammal assemblages) from the same site, which suggest slightly warmer and drier conditions. We hypothesise that these divergences may be partly related to the current wide distribution of reptiles and amphibians across Iberia. A key finding is that the extirpation of the Neanderthals in Iberia coincided with aridification.

The content of astrophysical jets Romero, Gustavo Esteban Jets, collimated outflows of particles and fields, are observed in a wide variety of astrophysical systems, including Active Galactic Nuclei of various types, micro-quasars, gamma-ray bursts, and young stellar objects. Despite intensive efforts along several decades of observational and theoretical research, there are still many uncertainties and open questions related to how jets are produced and what is their composition. In this review, I offer an outline of some current views on the content and basic properties of astrophysical jets.

Towards the design of biodiverse green roofs in Argentina: Assessing key elements for different functional groups of arthropods Fabian, Diego; González, Ezequiel; Sánchez Domínguez, María Virginia; Salvo, Silvia Adriana; Fenoglio, Maria Silvina Green roofs offer numerous environmental benefits, and thus their implementation is considered an initiative to create sustainable cities. However, the characteristics of green roofs that could enhance arthropod biodiversity and ecological functioning are poorly known, especially for South American countries. Here, we analyzed the influence of several characteristics of green roofs (plant species richness, vegetation cover of the roof, age, substrate depth, area, and isolation in terms of height and green cover in the landscape scale) on the abundance, richness (total and by functional feeding groups), and community composition of arthropods. To do that, we selected 30 green roofs located in different urbanization contexts, from small towns in semi-rural areas to Cordoba, the second-largest city of Argentina. Our results indicated a high diversity of arthropods, registering a total of 12,942 individuals corresponding to 505 species from 14 orders, being herbivores and parasitoids the dominant groups. The area of the green roofs was positively linked to total species richness, species richness of most functional feeding groups, and total abundance of arthropods. The community composition of arthropods on green roofs was also affected by their area, and by the green cover in the landscape. Moreover, green roofs with higher plant richness, mainly spontaneous, and less isolated (both vertically and horizontally) favored entomophagous arthropods. Other variables, such as age and vegetation cover of the green roofs, were also important for herbivores, predators, parasitoids and detritivores. Our study clearly demonstrates that green roof size is not all that matters for supporting arthropod biodiversity because promoting high plant diversity, allowing spontaneous ecosystem dynamics, and diminishing roof isolation foster entomophagous arthropod diversity. Our study is the first that considers multiple factors of roofs in South America and provides key knowledge for stakeholders interested in the development and management of this green infrastructure in semi-rural and urban landscapes.

Incipient speciation in Calceolaria polyrhiza complex (Calceolariaceae): Cytogenetic analysis supports molecular and morphological data Mermoud, Sebastian Ricardo; Cosacov Martinez, Andrea; Sersic, Alicia Noemi; Acosta, María Cristina Calceolaria polyrhiza is a perennial herb distributed in southern South America. The species is highly polymorphic and includes four described morphotypes that were previously considered different species. We performed a detailed study of the karyotype of each morphotype considering at least two localities for each one, with the aim of contributing to the taxonomic delimitation of the Calceolaria polyrhiza complex. In addition, a principal component analysis and a mapping of chromosome traits onto a phylogeny of nuclear DNA sequences were performed. This detailed karyotypic study has revealed specific markers, which have allowed to characterize each morphotype. ‘Prichardii’ morphotype was consistently polyploid. ‘Mendocina’ and ‘Lanceolata’ morphotypes had the highest total heterochromatin amount, with two pairs of chromosomes carrying NORs. ‘Mendocina’ samples showed the most asymmetrical karyotypes. ‘Polyrhiza’ morphotype had the most symmetrical karyotypes of the four morphotypes and the simplest fluorescent chromosome banding pattern. Thus, the four morphotypes could be characterized by chromosomal data and, together with the phylogenetic analysis of molecular data, could be considered taxonomic units in the process of diversification.

Defying death: incorporating fossils into the phylogeny of the complex thalloid liverworts (Marchantiidae, Marchantiophyta) confirms high order clades but reveals discrepancies in family-level relationships Flores, Jorge Rafael; Bippus, Alexander C.; Suarez, Guillermo Martin; Hyvönen, Jaakko In recent years, the use of extensive molecular and morphological datasets has clarified the phylogenetic relationships among the orders of complex thalloid liverworts (Marchantiidae). However, previous studies excluded extinct taxa; thereby, undersampling the actual taxonomic diversity of the group. Here, we conducted a total-evidence analysis of Marchantiidae incorporating fossils. The combined dataset consisted of 11 genes—sampled from the nuclear, mitochondrial and plastid genomes—and 128 morphological characters. Sixty-two species, representing all classes and orders within Marchantiophyta and genera within Marchantiidae were included in the analyses. Six fossils were scored from literature: two assigned to the outgroup (Metzgeriothallus sharonae and Pallaviciniites sandaolingensis) and four to the ingroup (Marchantites cyathodoides, M. huolinhensis, Ricciopsis ferganica and R. sandaolingensis). Tree searches were conducted using parsimony as the optimality criterion. Clade sensitivity was assessed across a wide range of weighting regimes. Also, we evaluated the influence of fossils on the inferred topologies and branch support. Our results were congruent with previously inferred clades above the order level: Neohodgsoniales was sister to a clade formed by Sphaerocarpales and Marchantiales. However, relationships among families within Marchantiales contradicted recent studies. For instance, a clade consisting of Monosoleniaceae, Wiesnerellaceae and Targioniaceae was sister to the morphologically simple taxa instead of being nested within them as in previous studies. Novel synapomorphies were found for several clades within Marchantiales. Outgroup fossils were more influential than Marchantiidae fossils on overall topologies and branch support values. Except for a single weighting scheme, sampling continuous characters and down-weighting characters improved fossil stability. Ultimately, our results challenge the widespread notion that bryophyte fossils are problematic for phylogenetic inference.

La configuración de necroespacialidades vivenciadas por adolescentes varones implicados con el narcotráfico en las periferias pobres del gran Buenos Aires, Argentina; A configuração de necroespacialidades vivenciadas por adolescente do sexo masculino envolvidos com o narcotráfico nas periferias pobres da Grande Buenos Aires, Argentinas; The Configuration of Necro-spacialities Experienced for Male Adolescents Involved with Drug Trafficking in Poor Peripheries of Greater Buenos Aires, Argentina Rocha, Heder Leandro; Lan, Diana Graciela Este texto objetiva la comprensión de cómo se configuran las necroespacialidades en la vivencia cotidiana de los adolescentes varones implicados con el narcotráfico en las periferias pobres del Gran Buenos Aires (GBA). Fueron realizadas 13 entrevistas en profundidad con adolescentes varones en tratamiento por el policonsumo problemático de drogas y que en algún momento de sus vidas estuvieron implicados con el narcotráfico. Se utilizó como metodología el análisis de contenido del discurso (Bardin, 1977) y la sistematización por frecuencia y espacialidad de las categorías discursivas, conforme la propuesta de Gomes (1993). A partir de este análisis fue posible identificar las formas por las cuales el accionar biopolítico y necropolítico instituyen necroespacialidades vivenciadas de forma multiescalar por los sujetos. El barrio, la calle, la casa y el propio cuerpo son vivenciados a partir de la muerte violenta en las periferias pobres que viven estos adolescentes.; O presente texto objetiva a compreensão de como as necroespacialidades são configuradas nas experiências diárias de adolescentes envolvidos com o tráfico de drogas nas periferias pobres da Grande Buenos Aires (GBA). Foram realizadas 13 entrevistas em profundidade com adolescentes do sexo masculino em tratamento para o policonsumo problemático de drogas, que em algum momento de suas vidas estavam envolvidos com o tráfico de drogas. Se utilizou como metodologia a análise do conteúdo do discurso (Bardin, 1977) e a sistematização por frequência e espacialidade das categorias discursivas, conforme proposta de Gomes (1993). A partir da análise realizada foi possível identificar como os dispositivos da biopolítica e da necropolítica instituem necroespacialidades que são vivenciadas de forma multiscalar pelos sujeitos. O bairro, a rua, a casa e o próprio corpo são vivenciados a partir da morte violenta nas periferias pobres que esses adolescentes vivem.; This text aims to understand how necro-spatialities are configured in the daily experience of male adolescents involved with drug trafficking in the poor peripheries of Greater Buenos Aires (GBA). Thirteen in-depth interviews were conducted with male adolescents in treatment for problematic drug use and who at some point in their lives were involved with drug trafficking. Discourse content analysis (Bardin, 1977) and the systematization by frequency and spatiality of discursive categories were used as methodology, according to the proposal of Gomes (1993). From this analysis it was possible to identify the ways in which biopolitical and necropolitical actions institute necro-spatialities experienced in a multiscalar way by the subjects. The neighborhood, the street, the house and the body itself are experienced from the violent death in the poor peripheries that these adolescents live.

Diabetes mellitus remission in three cats with hypersomatotropism after cabergoline treatment Miceli, Diego Daniel; Vidal, Patricia Noemi; Pompili, Gustavo A; Castillo, Víctor A; Soler Arias, Elber A; Niessen, Stijn JM Three diabetic cats presented with polyuria, polydipsia, polyphagia and poor glycemic control. Cat 1 displayed prognathia inferior and had a body condition score (BCS) of 4/5; cat 2 had a BCS of 5/5; and cat 3 had broad facial features. Serum insulin-like growth factor 1 concentrations were compatible with hypersomatotropism in cat 1 and cat 2 (>1500 ng/ml and 1200 ng/ml, respectively) and just below the cut-off of 1000 ng/ml (947 ng/ml) in cat 3; in this last cat diagnosis was further supported by the presence of pituitary enlargement on MRI. Oral cabergoline (10 μg/kg q48h) was initiated. Insulin requirements progressively reduced, as evidenced by daily blood glucose monitoring and weekly blood glucose curves. Diabetic remission occurred in all three cats between the second and third months of cabergoline treatment. At the time of writing, remission has persisted thus far (cat 1: 23 months; cat 2: 14 months; cat 3: 38 months). Relevance and novel information: To our knowledge, these are the first reported cases of diabetic remission in cats with hypersomatotropism after cabergoline treatment, despite previous reports of this being an ineffective treatment. Further work is indicated to determine why some cats do, and others do not, respond to this treatment.

Memorias silenciadas y memorias patrimonializadas: identidades indígenas y gauchescas en el sudoeste bonaerense (Argentina); Silenced memories and patrimonialized memories: indigenous and gauchescas identities in the southwest of Buenos Aires (Argentina) Hernán, Perriere En el presente artículo considero los procesos de patrimonialización estatal en el sudoeste de la provincia de Buenos Aires (Argentina). El objetivo es presentar un relevamiento de Monumentos y Lugares Históricos y “Fiestas Gauchas” para focalizar en dos activaciones patrimoniales donde los pueblos indígenas son silenciados y la figura del gaucho es evocada y sus saberes, prácticas y conocimientos patrimonializados. Analizo las declaraciones patrimoniales del Fortín Cuatreros como Monumento Histórico Nacional y la Fiesta de la Llanuras como fiesta representativa de la tradición gauchesca. Estas declaraciones se complementan con el análisis de artículos periodísticos y videos de internet. La hipótesis es que las políticas estatales de patrimonialización que recurren a las identificaciones relativas a lo gauchesco y lo indígena han sido diferenciadas, y esto incide en los procesos de memorias que se trasmiten intergeneracionalmente.; In this article, we consider the state patrimonialization processes in the southwest of the province of Buenos Aires (Argentina). The objective is to present a survey of Monuments and Historic Places and “Fiestas Gauchas” to focus on two patrimonial activations where indigenous peoples are silenced and the figure of the gaucho is evoked and his knowledge, practices and heritage heritage. I analyze the patrimonial declarations of the Fortín Cuatreros as a National Historic Monument and the Fiesta de las Llanuras as the representative festival of gaucho tradition. These statements are complemented by the analysis of newspaper articles and internet videos. The hypothesis is that the state patrimonialization polics that are repeated to the identifications related to the gaucho and the indigenous have been differentiated, and this affects the memory processes that are transmitted intergenerationally.

The impact of socioeconomic and phenotypic traits on self-perception of ethnicity in Latin America Paschetta, Carolina Andrea; de Azevedo, Soledad; Ramallo, Virginia; Cintas, Celia; Pérez, Orlando Alberto; Navarro, Jose Pablo; Bandieri, Lucas Martín; Quinto Sánchez, Mirsha Emmanuel; Adhikari, Kaustubh; Bortolini, Maria Catira; Poletti Ferrara, Giovanni; Gallo, Carla; Bedoya Berrío, Gabriel; Rothhammer, Francisco; Alonzo, Victor Acuña; Ruiz Linares, Andrés; González José, Rolando Self-perception of ethnicity is a complex social trait shaped by both, biological and non-biological factors. We developed a comprehensive analysis of ethnic self-perception (ESP) on a large sample of Latin American mestizos from five countries, differing in age, socio-economic and education context, external phenotypic attributes and genetic background. We measured the correlation of ESP against genomic ancestry, and the influence of physical appearance, socio-economic context, and education on the distortion observed between both. Here we show that genomic ancestry is correlated to aspects of physical appearance, which in turn affect the individual ethnic self-perceived ancestry. Also, we observe that, besides the significant correlation among genomic ancestry and ESP, specific physical or socio-economic attributes have a strong impact on self-perception. In addition, the distortion among ESP and genomic ancestry differs across age ranks/countries, probably suggesting the underlying effect of past public policies regarding identity. Our results indicate that individuals’ own ideas about its origins should be taken with caution, especially in aspects of modern life, including access to work, social policies, and public health key decisions such as drug administration, therapy design, and clinical trials, among others.

Biodiversity and the challenge of pluralism Pascual, Unai; Adams, William M.; Díaz, Sandra Myrna; Lele, Sharachchandra; Mace, Georgina M.; Turnhout, Esther The lack of progress in reversing the declining global trend in biodiversity is partly due to a mismatch between how living nature is conceived and valued by the conservation movement on the one hand, and by many different people, including marginalized communities, on the other. Addressing this problem calls for a pluralistic perspective on biodiversity. This requires consideration of the use of the concept of biodiversity, willingness to expand its ambit, and engagement with the multiple and multi-level drivers of change. We propose ways for conservation science, policy and practice to deliver more effective and socially just conservation outcomes.

Creative activities, emotions, and resilience during the COVID-19 pandemic: a longitudinal study from Argentina Elisondo, Romina Cecilia ObjectivesWe conducted a longitudinal study to analyze emotions that are related to the development of creative activities during isolation and social distancing that are associated with the COVID-19 pandemic.Study designThe study was performed in two stages: beginning of isolation (April 2020) and 6 months later during the social distancing period (September 2020).MethodsA total of 305 people who resided in medium-sized cities (population: 50,000 to one million) in the province of Córdoba, Argentina, participated in the study. In the first stage, the participants answered an online questionnaire about creative activities in which they engaged during isolation. In the second stage, semistructured interviews were conducted that asked about changes in life, creative processes, and new endeavors during the social distancing period.ResultsIn April 2020, positive emotions were associated with the development of creative activities. In September 2020, a predominance of negative emotions that were related to economic, family, and personal difficulties was observed. However, some positive emotions that are related to the development of new ventures and the consolidation of healthy and sustainable habits were also found.ConclusionsWe highlight the value of creativity as a resilience factor in the development of new projects and postponed activities. Our findings may contribute to the design and development of policies and programs to promote mental health in times of COVID-19.

Las mujeres de la Agrupación Artística Maná: vínculos entre docencia y gestión cultural, Azul, años treinta y cuarenta; The women of the Artistic Association Maná: links between teaching and cultural management, city of Azul, 1930s and 1940s González, María Soledad La Agrupación Artística Maná se creó en la ciudad de Azul (Buenos Aires, Argentina) en 1932 con el objetivo de oficiar como puente con otras localidades de la provincia en el marco de un clima de florecimiento cultural que venía produciéndose desde fines de los veinte. Dicho espacio de sociabilidad funcionó a partir de un grupo selecto, que se propuso difundir la cultura estableciendo vínculos artísticos e intelectuales que incluso fueron más allá del marco provincial. En este artículo nos ocuparemos del proyecto de esta institución, entendiéndolo como una “obra pedagógica” y analizaremos el papel que allí tuvieron las mujeres a partir de una labor que conjugaba docencia y gestión cultural.; The Maná Artistic Association was created in the city of Azul in 1932 with the objective of culturally connecting the city with other towns in the province of Buenos Aires in a context of cultural flourishing that had been taking place since the late1920s. Such space of sociability worked as a selected group, which promoted culture through artistic and intellectual projects that went beyond the province of Buenos Aires. This article analyzes the nature of this institution, understanding it as a "pedagogical work" and it focuses on the role that women had in combining both teaching and cultural management.
