Nonylphenol releases arachidonic acid in rat Sertoli cells via activation of PKA and PLA2 Santiago Valtierra, Florencia Ximena; Urriola-Muñoz, Paulina; Godoy-Sepúlveda, Rodrigo; Moreno, Ricardo D.; Reyes, Juan G; Valles, Ana Sofia; Oresti, Gerardo Martin Nonylphenol (NP), an endocrine-disrupting chemical, is an environmental contaminant, and many notorious effects on male fertility have been reported in animal models and wild-type species. Here, we evaluated the effects of NP in follicle-stimulating hormone (FSH) signal transduction pathways and lipid metabolism using an in vitro model of rat Sertoli cell (SC) primary culture. Results show that an acute (1 h) SC exposure to NP (10 µM) increased the intra- and extra-cellular concentrations of free fatty acids (FFAs), mainly arachidonic acid (20:4n-6). Phosphatidylinositol seemed to be the major phospholipid source of this 20:4n-6 release by activation of the protein kinase A (PKA)/cytoplasmic phospholipase A2 (cPLA2) pathway. NP also increased diacylglycerols (DAG) levels and the expression (mRNA) of cyclooxygenase 2 (Cox2) and prostaglandin E2 (PGE2) levels. It is noteworthy that accumulation of lipid droplets took place after 24 h NP exposition, which was prevented by both a PKA inhibitor and a PLA2 inhibitor. Like FSH, NP triggers the release of 20:4n-6, which is a substrate for PGE2 synthesis via PKA/PLA2 activation. In addition, NP induces the formation of DAG, which could be required as a cofactor of the PKC-mediated activation of the COX2 inflammatory pathway. Our findings suggest that NP alters lipid homeostasis in SCs by inducing the activation of pro-inflammatory pathways that may trigger adverse effects in testis physiology over time. Concomitantly, the SC enhances the acylation of surplus FFAs (including 20:4n-6) in neutral lipids as a protective mechanism to shield itself from lipotoxicity and pro-inflammatory signals

Secuenciación masiva de miARNs en una población susceptible y una resistente a insecticidas piretroides del vector de la Enfermedad de Chagas Triatoma infestans Se extrajo ARN total y miARNs a partir de ninfas de estadio V de la colonia susceptible originada a partir de individuos provenientes de la localidad de Chuña y de la colonia resistente de Pampa Argentina. Cada muestra consistió en un pool cuerpo graso de 5 machos y 5 hembras. La extracción se realizó mediante el kit mirVanaTM miRNA Isolation de acuerdo a las instrucciones del fabricante. Se verificó la concentración de ARN total (fluorómetro Qubit) e integridad del mismo por electroforesis desnaturalizante en gel de agarosa. Para la secuenciación de nueva generación (NGS) se remitieron las muestras de ARN total para la construcción de las librerías y la secuenciación masiva al servicio técnico especializado brindado por la empresa ArrayStar (EEUU). Para el análisis bioinformático de Raw data de más de 64 (Ti1R), 72 (Ti2R) y 93(Ti3R) millones y 50 (Ti1S), 146 (Ti2S) y 67 (Ti3s) millones de lecturas sin procesar de las réplicas S1, S2 y S3 de poblaciones susceptibles y R1, R2 y R3 respectivamente se utilizaron herramientas del programa CLC Genomics Workbench v9.5. Se procesaron los datos crudos para remover lecturas de baja calidad, de secuencias poliA, de adaptadores, de secuencias sin adaptador 3’ y de secuencias más cortas a 15 nucleótidos. Se obtuvieron 62 (Ti1R), 70 (Ti2R) y 90 (Ti3R) millones de lecturas procesadas y 48 (Ti1S), 143 (Ti2S) y 65 (Ti3S) millones de lecturas procesadas. Los datos de lecturas recortadas de cada biblioteca se anotarán mediante su comparación con la base de datos de miARNs de miRBase, así también como con miARNs que se caracterizarán a partir del genoma de R. prolixus y con las secuencias de transcriptomas de T. infestans, T. dimidiata y T. pallidipennis, y otras especies de hemípteros presentes en la base de datos Vectorbase. Subsecuentes recuentos relativos de miARNs se realizaron dentro de cada librería. Para predecir nuevos miARNs se utilizó el software miRDeep2. Utilizando el program miRDeep 2 se identificaron 120 miARNs y se caracterizaron 20 miARNs nuevos. Se encuentra en desarrollo el análisis de la expresión diferencial de miARNs entre las poblaciones de T. infestans susceptible y resistente a insecticidas piretroides se determinan los niveles de expresión de las miARNs se lleva a cabo con el comando “Annotate and Merge” en el programa CLC Genomics Workbench v9.5. Este procedimiento utilizó a miRBase como base de datos primaria y la base de datos de ARNs no codificantes (dmell-RNAt-6.1/8fasta y demell-allmiscRNA-6.1/8.fasta) como base de datos secundaria de anotación. El número de lecturas se normalizó usando el método de etiquetas por millón de lecturas o método de TPM. TPM= (número de lecturas corridas por cada miARN en relación al total de lecturas corridas) x 106. Posteriormente, el algoritmo de Análisis Empírico de la Expresión Diferencial del Gen (Empirical Analisys of Differential Gene Expression o EDGE) se utilizó para estimar las diferencias en el número de lecturas para las poblaciones susceptible y resistente, con valores P ajustados por cálculos de múltiples pruebas, empleando el procedimiento de Benjamini-Hochberg para tasa de falso descubrimiento (false discovery rate: FDR).

Supplementary Material 1. Matrix of data for the ordination analysis performed Southern Patagonia contains several Eocene fossiliferous deposits that have only been superficially explored and studied. One of these corres- ponds to the La Marcelina Formation with outcrops in the south-western slope of the Deseado Massif, Santa Cruz Province, Argentina. No de- tailed palynological studies have been performed so far in this unit. Here we estimate the age, palaeoenvironment, and climatic conditions based on the analysis of terrestrially derived spores, algae cysts, and pollen grains. The recovered association supports an Eocene age and concurs with a mixed flora, including Gondwanan and Neotropical elements, dominated by Podocarpaceae, Nothofagaceae, and Proteaceae, and that probably developed under a temperate and humid climate. Overall, these results expand our understanding of the composition of Eocene floras from the highest latitudes of South America, as well as provide new evidence of past paleoclimates for the area.

Experimentos para la reacción de RWGS sobre catalizador de Pd 0.08%pp -Ce 3,84%pp para una mezcla de alimentación CO2/H2/CH4/Ar a P=1.6 bar: referencia para comparación de alimentaciones Para la reacción de RWGS a P=1.6 bar y T=600°C, sobre catalizador de Pd 0.08%pp -Ce 3,84%pp, se realizaron experimentos con una alimentación CO2/H2/CH4/Ar. Estas corridas se toman como referencia para estudiar diversos efectos con comparación de alimentaciones. Los experimentos para el estudio cinético se llevaron a cabo en un reactor tubular de lecho fijo localizado en un laboratorio del PLAPIQUI. Para la recopilación de datos experimentales se utilizó un tubo de cuarzo de 1 m de longitud con un diámetro interno de 10 mm, ubicado dentro de un horno eléctrico Lindberg-Blue M con tres zonas de calentamiento independientes. Cargas de catalizador entre 10 y 100 mg se colocaron en el tubo entre tapones de lana de cuarzo. El reactor es alimentado por tubos de gas de CH4, H2, CO2 y Ar regulados por un controlador y sus respectivos caudalímetros. El flujo de salida del reactor se dirige hacia una trampa de agua (lecho fijo de sílica gel y tamiz molecular) y luego se analiza en un cromatógrafo de gases Perkin Elmer Autosystem utilizando argón como gas portador y operado con un detector de conductividad térmica (TCD). Antes de cada experimento, el catalizador fresco se reduce con un flujo de hidrógeno durante media hora.

On-Farm single strip treatment trials The dataset comprises data collected from six unreplicated on-farm experiments (OFE) conducted in Córdoba, central Argentina. These experiments included three field trials of corn (Zea mays L.), designated as F1, F2, and F3, and three field trials of soybean (Glycine max (L.) Merr.), designated as F4, F5, and F6. Trials F1 and F6 were conducted under irrigated conditions, while the others were rainfed. In F1, the effects of a starter fertilizer on corn were assessed using two single strips: Treated, with a fertilizer application rate of 100 kg ha–1 [21-17-3 + 1% MgO + 5% S + 0.1% Zn], and Control, with no fertilizer (0 kg ha–1). Each strip was 1.1 ha in area, totaling 34 ha. In F2, the impact of broadcast phosphorus (P) fertilization was evaluated. The treatment strip received superphosphate at rates ranging from 250 to 500 kg ha–1 [0-21-0], while the control strip received no P fertilizer (0 kg ha–1). Each strip was 2.2 ha in area, totaling 100 ha. In F3, the OFE focused on the effect of foliar zinc application at the V4 growth stage. The treated strip received a dose of 2 L ha-1 (700 g L-1), while the control strip received no zinc (0 L ha-1). Each individual strip was 2 ha in area (500 m long × 40 m wide), totaling 68 ha. In F4 and F6, the effectiveness of foliar boron (B) fertilization at the R3 growth stage was evaluated. For F4, the treated strip, which covered an area of 2 ha (680 x 30 m), received 1 L ha–1 (150 g L-1), while the control strip received no boron (0 L ha–1), and was 1.8 ha in area (640 m x 30 m) on a 42-ha field. For F6, the treated strip received 2 L ha–1 (150 g L-1) and covered an area of 4.9 ha, while the control strip (0 L ha–1) covered 7.5 ha on a 59-ha field. In F5, the OFE assessed the impact of broadcast phosphorus (P) fertilization on soybean. The treated strip received triple superphosphate containing calcium at rates ranging from 250 to 500 kg ha–1 [0-46-0 + 15% Ca], while the control strip received no P fertilizer (0 kg ha–1). The plot covered 61 ha, with strip dimensions of 450 x 50 m, resulting in areas of 2.3 ha for the treatment and control.

To move or not to move: Dispersal of Orius insidiosus in strawberry plants Alonso, Mariángeles; Guisoni, Nara Cristina; Rocca, Margarita; Greco, Nancy Mabel Spatial and temporal distribution of food resources influences predatory insects´ foraging and dispersal behavior. Orius insidiosus (Say) (Hemiptera: Anthocoridae) is a good biological control agent of western flower thrips (WFT), Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), in the strawberry crop and consumes two-spotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae), and pollen as well. Augmentative biological control programs may fail if, following release, predators disperse from the crop. We studied the dispersal of O. insidiosus as a function of pollen availability, density of their main prey WFT, and the presence of the alternative prey TSSM, within and between strawberry plants. We found that O. insidiosus remained on the flowers during the 24h of the assay. The dispersal of predators to a neighboring flower with thrips was approximately six times greater from a flower without pollen than from a flower with pollen. When TSSM was the only prey available, O. insidiosus colonized the leaves, and its dispersal within the plant was greater. At the plot scale, the predator dispersal from the release plant to other plants also depended on the presence of flowering plants and prey. Our results highlight the importance of flowering plants and pollen availability in enhancing the persistence of O. insidiosus in strawberry plants. Releases of this predator in the strawberry crop should be after the beginning of flowering, even at low WFT densities.

Elucidating solvent effects on lipase‐catalyzed peroxyacid synthesis through activity‐based kinetics and molecular dynamics Brandolin, Salvador Eduardo; Scilipoti, José Antonio; Magario, Ivana Peroxyacid synthesis is the first step in Prilezhaev epoxidation, which is an industrial method to form epoxides. Motivated by the development of a kinetic model as a tool for solvent selection, the effect of solvent type and acid chain length on the lipase-catalyzed peroxyacid synthesis was studied. A thermodynamic activity-based ping-pong kinetic expression was successfully applied to predict the effect of the reagent loadings in hexane. The activity-based reaction quotients provided a prediction of solvent-independent equilibrium constants. However, this strategy did not achieve satisfactory estimations of initial rates in solvents of higher polarity. The lack of compliance with some assumptions of this methodology could be confirmed through molecular dynamics calculations i.e. independent solvation energies and lack of solvent interaction with the active site. A novel approach is proposed combining the activity-based kinetic expression and the free binding energy of the solvent with the active site to predict kinetics upon solvent change. Di-isopropyl ether generated a strong interaction with the enzyme´s active site, which was detrimental to kinetics. On the other hand, toluene or limonene gave moderate interaction with the active site rendering improved catalytic yield compared with less polar solvents, a finding sharpened when peroctanoic acid was produced.

Vitamin D3 supplementation in COVID-19 patients with cardiovascular disease and gut dysbiosis Sanz, R. L.; García, F.; Gutierrez, A.; García Menéndez, Sebastián Marcelo Manuel; Inserra, F.; Ferder, L.; Manucha, Walter Ariel Fernando Background: The COVID-19 pandemic has highlighted the vulnerability of particular patient groups to SARS-CoV-2 infection, including those with cardiovascular diseases, hypertension, and intestinal dysbiosis. COVID-19 affects the gut, suggesting diet and vitamin D3 supplementation may affect disease progression. Aims: To evaluate levels of Ang II and Ang-(1-7), cytokine profile, and gut microbiota status in patients hospitalized for mild COVID-19 with a history of cardiovascular disease and treated with daily doses of vitamin D3. Methods: We recruited 50 adult patients and accessed pathophysiology study 22, randomized to daily oral doses of 10,000 IU vitamin D3 (n=11) or placebo (n=11). Plasma levels of Ang II and Ang-(1-7) were determined by radioimmunoassay, TMA and TMAO were measured by liquid chromatography and interleukins (ILs) 6, 8, 10 and TNF-α by ELISA. Results: The Ang-(1-7)/Ang II ratio, as an indirect measure of ACE2 enzymatic activity, increased in the vitamin D3 group (24±5 pg/mL vs 4.66±2 pg/mL, p<0.01). Also, in the vitamin D3-treated, there was a significant decline in inflammatory ILs and an increase in protective markers, such as a substantial reduction in TMAO (5±2 µmoles/dL vs 60±10 µmoles/dL, p<0.01). In addition, treated patients experienced less severity of infection, required less intensive care, had fewer days of hospitalization, and a reduced mortality rate. Additionally, improvements in markers of cardiovascular function were seen in the vitamin D3 group, including a tendency for reductions in blood pressure in hypertensive patients. Conclusions: Vitamin D3 supplementation in patients with COVID-19 and specific conditions is associated with a more favourable prognosis, suggesting therapeutic potential in patients with comorbidities such as cardiovascular disease and gut dysbiosis.

Prevalence of congenital anomalies and prenatal diagnosis by birth institution (public vs. non-public): indicators of inequality in access to elective termination of pregnancy for fetal anomalies Brun, Paloma Laura; Groisman, Boris; Bidondo, Maria Paz; Barbero, Pablo Miguel; Trotta, Marianela; Liascovich, Rosa Congenital anomalies (CA) encompass all morphological or functional alterations originating prenatally and present at birth. The prenatal diagnosis of these anomalies can signifcantly impact the overall health of the pregnant individual and may infuence her decision regarding the continuation of the pregnancy. In contexts where safe pregnancy termination is not guaranteed by the state, it can lead to unsafe procedures with severe consequences. In our research, we analyzed epidemiological information on CA to develop potential indicators of inequity in access to safe abortion prior to the legalization of legal termination of pregnancy in Argentina. We included cases from 13 public hospitals and 9 non-public subsector hospitals, from the period 2013–2020. Two groups of specifc CA were selected: 1) CA capable of being prenatally diagnosed, and 2) CA related to vascular disruptive events. 10/18 of the selected CA capable of being prenatally diagnosed had a signifcantly higher prevalence in public hospitals (anencephaly, encephalocele, spina bifda, microcephaly, hydrocephalus, holoprosencephaly, hydranencephaly, diaphragmatic hernia, gastroschisis, bilateral renal agenesis). Non public hospitals had higher prenatal detection. Birth prevalence of CA related with vascular disruptive events (limb reduction, Moebius syndrome, amniotic band sequence) were signifcantly higher in public hospitals. These results suggest disparities in access to prenatal diagnosis and safe abortion based on socioeconomic status. There was a signifcant gap in access to prenatal diagnosis for CA and possibly to safe elective abortion depending on the type of institution (public vs. non-public).

Mapeo participativo de tecnologías de acceso al agua en el Chaco salteño (noroeste argentino): Avances de una experiencia colaborativa; Participatory mapping of water access technologies in the Chaco of Salta (northwest Argentina): Advances of a collaborative experience; Mapeamento participativo de tecnologias de acesso à água no Chaco de Salta (noroeste da Argentina): Avanços de uma experiência colaborativa López, Emilce de Las Mercedes; Belmonte, Silvina Conocer y mostrar espacialmente las distintas formas de acceso al agua en hábitats rurales del Chaco salteño, representa un gran desafío. Para enfrentarlo nos propusimos mapear esas formas de acceso al agua en la zona sistematizar los resultados e incorporarlos a un Sistema de Información Geográfica. La necesidad de este relevamiento surgió a partir de un trabajo colaborativo con las mesas locales de agua (Rivadavia Banda Norte) y de gestión local (La Unión – Rivadavia Banda Sur). Mediante técnicas de cartografía social se identificaron las principales formas de acceso al agua en los diversos parajes, puestos criollos y comunidades originarias de estos municipios. En el espacio provisto por las mesas locales se realizó una priorización que permitió ubicar espacialmente áreas de mayor necesidad de gestión del recurso hídrico. El uso de los sistemas de información geográfica tiene la ventaja de brindar una visión espacial e integral sobre el territorio y en este caso sobre la situación de acceso al agua, de potencial utilidad para la toma de decisiones informadas y la implementación de políticas hídricas efectivas en el Chaco salteño.; Knowing and spatially showing the different forms of access to water in the rural habitats of the Chaco de Salta represents a great challenge. To address this, we proposed to map these forms of access to water in the area, systematize the results and incorporate them into a Geographic Information System. The need for this survey arose from collaborative work with local groundwater (Rivadavia Banda Norte) and local management (La Unión – Rivadavia Banda Sur). Using social mapping techniques, the main forms of access to water in different locations, creole posts and communities originating in these municipalities were identified. In the space provided by the local tables, a prioritization was carried out that made it possible to spatially locate the areas most in need of water resources management. The use of geographic information systems has the advantage of providing a spatial and comprehensive view of the territory and, in this case, the water access situation, potentially useful for making informed decisions and affective water policies in the Chaco de Salta.; Conhecer e mostrar espacialmente as diferentes formas de acesso à águanos habitats rurais do Chaco de Salta representa um grande desafio. Para enfrentá-lo, propusemos mapear essas formas de acesso à água na área, sistematizar os resultados e incorporá-los em um Sistema de Informação Geográfica. A necessidade deste levantamento surgiu do trabalho colaborativo com os lençóis freáticos locais (Rivadavia Banda Norte) e a gestão local (La Unión –Rivadavia Banda Sur). Utilizando técnicas de mapeamento social, foram identificadas as principais formas de acesso à água nos diversos locais, postos crioulos e comunidades originárias desses municípios. No espaço disponibilizado pelas tabelas locais, foi realizada uma priorização que permitiu localizar espacialmente as áreas de maior necessidade de gestão de recursos hídricos. A utilização de sistemas de informação geográfica tem a vantagem de proporcionar uma visão espacial e abrangente do território e, neste caso, da situação de acesso à água, potencialmente útil para a tomada de decisões informadas e a implementação de políticas hídricas eficazes no Chaco de Salta.

Transformaciones y continuidades en la gestión policial de conflictividades durante la pandemia: El caso de Villa María (Córdoba, Argentina); Transformations and continuities in the police management of conflicts during the pandemic: The case of Villa María (Córdoba, Argentina) Goldin, Déborah Judith; Rodríguez, Florencia Este artículo presenta los resultados de una investigación sobre las transformaciones en las prácticas de policiamiento y control poblacional durante la pandemia por el COVID-19, y los modos en que estos cambios fueron experienciados por los y las policías de Córdoba (Argentina), en el caso del aglomerado Villa María-Villa Nueva durante los años 2020-2021. Aquí abordaremos las conflictividades que fueron relevantes en la localidad durante este período, analizando las transformaciones que se identificaron en las prácticas policiales y sus modos de intervención sobre estos conflictos. Luego, analizaremos las interacciones entre policía y ciudadanía, buscando evidenciar las transformaciones de este vínculo de por sí heterogéneo. Finalmente, indagaremos en las experiencias de los y las policías durante la pandemia, con especial énfasis en su percepción del riesgo y del reconocimiento de su labor, como así también sobre el uso de la fuerza. A partir de este recorrido, consideramos que la pandemia fortaleció el papel de la policía en la gestión poblacional, evidenciando aún más la realización de un abanico de tareas desvinculadas de la persecución del crimen.; This article presents the results of a research on the transformations in policing practices and population control during the COVID-19 pandemic, and the ways in which these changes were experienced by police officers in Córdoba (Argentina), in the case of the Villa María-Villa Nueva urban agglomerate during 2020-2021. Here we will address the conflicts that were relevant in this location during said period, analyzing the transformations that were identified in police practices and their ways of intervening in these conflicts. We analyze the interactions between police and citizens, looking to highlight the transformations of this already heterogeneous relation. Finally, we will inquire into the experiences of the police during the pandemic, with special emphasis on their perception of risk and recognition of their work, as well as on the use of force. On this basis, we consider that the pandemic strengthened the role of the police in population management, further highlighting the performance of a range of tasks unrelated to the prosecution of crime.

Episodicity in accretion-ejection processes associated with IRAS 15398-3359 Guzmán Ccolque, Estrella; Fernandez Lopez, Manuel; Vazzano, María Mercedes; de Gregorio, I.; Plunkett, A.; Santamaría Miranda, A. Context. The protostar IRAS 15398-3359 is associated with a bipolar molecular outflow ejected in an nearly northeast–southwest (NE–SW) direction, which has been extensively studied. Previous episodic accretion events have been suggested by this source. Furthermore, the analysis of the morphology and kinematics of the molecular outflow revealed the presence of four 12CO (2–1) bipolarelliptical shock-like structures identified in both lobes. These structures seem to trace different ejections inclined ∼10◦from each otheron the plane of the sky. This led to the hypothesis that the outflow axis likely precesses and launches material episodically. Aims. Since several authors reached the conclusion of the same episodicity scenario by independent observations, IRAS 15398-3359has become an ideal target to empirically analyze the relationship between accretion and ejection processes.Methods. We analyzed ALMA archive observations in Band 6, revealing the presence of low-velocity (<3.5 km s−1) emission fromthe 12CO (2–1) line to the south and north of the protostar. We studied the morphology and kinematics of the gas; our study seems tosupport the hypothesis of a precessing episodic outflow.Results. The ALMA observations reveal a north–south (N–S) outflow most likely associated with the IRAS 15398-3359 protostellarsystem. This outflow could be older than the well-studied NE–SW outflow. The orientation of the N–S outflow is 50◦–60◦ on the planeof the sky away from that of the NE–SW outflow. We also analyzed the spectral energy distribution of a far away young star andpreliminarily discard it as the driver of the SE outflow remnants. Conclusions. The new observations support the hypothesis of strong episodic accretion-ejection events in IRAS 15398-3359, accompanied by dramatic changes in the orientation of its ejection axis, implying that all the outflows in the region may have been driven bythe same protostar
