ABSTRACT The collapse of the Fundão Dam in Mariana, MG, in 2015 introduced the challenge of using Technosol, a soil type formed by deposition of iron mining waste along the Doce River banks, for agricultural purposes. This study aimed to determine the optimal water depth for enhancing production of tropical forage, Megathyrsus maximus cv. Mombasa, when grown on iron ore tailings. Additionally, it sought to establish a crop coefficient applicable to the edaphoclimatic conditions of Viçosa, MG, Brazil. The experiment was conducted throughout the summer, fall, and winter of 2022, employing 21 drainage lysimeters. A completely randomized experimental design was adopted, featuring six treatment groups (plants in Technosol receiving water depths ranging from 20 to 120% of the crop’s evapotranspiration, as derived from the control treatment), along with a control group (plants in Latosol with a depth of 100%), each with three repetitions. Our findings showed that irrigation must replace 40% of the crop evapotranspiration. Moreover, cultivating in Technosol resulted in a reduction of productive capacity by 37.39% during the summer/fall and fall seasons. For Mombasa grass grown in Oxisol, crop coefficients of 1.2 during the summer and 1.5 during the fall and winter are advised.

RESUMO O rompimento da Barragem do Fundão em Mariana, MG, ocorrida em 2015, trouxe o desafio de usar o Tecnossolo (tipo de solo) formado pela deposição do rejeito de mineração de ferro nas margens do Rio Doce para agricultura. O objetivo desta pesquisa foi obter a lâmina de água para otimizar a produção da forragem tropical Megathyrsus maximum cv. Mombaça, cultivada em rejeito de mineração de ferro e determinar seu coeficiente de cultura para as condições edafoclimáticas de Viçosa, MG. O experimento foi realizado durante as estações de verão, outono e inverno do ano de 2022, com a utilização de 21 lisímetros de drenagem. O experimento foi distribuído em delineamento inteiramente casualizado com 6 tratamentos (plantas em Tecnossolo com lâminas variando de 20 a 120% da evapotranspiração da cultura, obtida do tratamento-testemunha) e adição de uma testemunha (plantas em Latossolo com lâmina de 100%) com três repetições. Recomenda-se irrigação com reposição de 40% da evapotranspiração da cultura. O cultivo em Tecnossolo diminuiu a capacidade produtiva em 37,39% nos ciclos das estações do verão/outono e outono. Recomenda-se os coeficientes de cultura de 1,2 no verão e 1,5 no outono e no inverno, para o capim-Mombaça cultivado em um Latossolo.

ABSTRACT The aim of this study was to evaluate the effect of Insulin-Transferrin-Selenium (ITS) supplementation in embryo culture on the blastocyst rate and embryo quality. The bovine zygotes obtained by in vitro maturation (MIV) and fertilization (IVF) were transferred to Evolve medium in 4 groups (T1: Without ITS supplement; T2: ITS the first 48 h of culture (CIV1): T3: ITS after day 2 of culture (CIV2), T4: ITS during all culture time (CIV1+CIV2). All procedures were performed at 38.5 °C,5%CO2and90%relativehumidity. The cleavage and blastocyst rates were determined at 48 h and day 8 of culture. The total cell number and the production of reactive oxygen species (ROS) in the expanded blastocysts were determined by staining the nucleus with Hoechst and the oxidation of the fluorescent probe dichlorodihydrofluorescein diacetate (H2DCFDA). The T4 cultured embryos presented the highest rate of blastocysts (32.6%) and total cell number (145.6) compared to the control group without STI (26.2% and 98.6, respectively; p<0.05). Likewise, the production of ROS in T4 blastocysts was lower (p<0.05) than that obtained in the other study groups. The results show that the addition of the ITS supplement throughout the embryo culture time has beneficial effects on the percentage of blastocysts and embryo quality, assessed by the number of total cells and the production of ROS.

RESUMEN El estudio tuvo como objetivo evaluar el efecto del suplemento Insulina-Transferrina-Selenio (ITS) en el cultivo embrionario sobre la tasa de blastocistos y calidad embrionaria. Los cigotos de bovino obtenidos por maduración (MIV) y fertilización in vitro (FIV) fueron transferidos a medio Evolve en 4 grupos (T1: Sin suplemento ITS; T2: ITS las primeras 48 h de cultivo (CIV1): T3: ITS después del día 2 de cultivo (CIV2), T4: ITS todo el tiempo de cultivo (CIV1 + CIV2). Todos los procedimientos se realizaron a 38.5 °C, 5% de CO2 y 90% de humedad relativa. Las tasas de clivaje y de blastocistos se determinaron a las 48 h y día 8 de cultivo, respectivamente. El número de células totales y la producción de especies reactivas de oxígeno (EROs) en los blastocistos expandidos fueron determinados por tinción del núcleo con Hoechst y la oxidación de la sonda fluorescente diacetato diclorodihidrofluoresceína (H2DCFDA). Los embriones cultivados de T4 presentaron la mayor tasa de blastocistos (32.6%) y número de células totales (145.6) comparada al grupo control sin ITS (26.2% y 98.6, respectivamente; p<0.05). Asimismo, la producción de EROs en los blastocistos de T4 fue menor (p<0.05) que la obtenida en los demás grupos de estudio. Los resultados demuestran que la adición del suplemento ITS durante todo el tiempo de cultivo embrionario tiene efectos benéficos sobre el porcentaje de blastocistos y calidad embrionaria, valorada por el número de células totales y la producción de EROs.

Resumen Objetivo: Describir la evolución de las cadenas livianas libres séricas (CLL) en el período comprendido entre el trasplante cardíaco ortotópico (TCO) y el trasplante de células progenitoras hematopoyéticas (TCPH), la respuesta hematológica al año tras el TCPH y el tratamiento quimioterápico e inmunosupresor en pacientes con amiloidosis AL. Método: Serie de casos de pacientes consecutivos con diagnóstico de amiloidosis AL que recibieron TCO seguido de TCPH del Registro Institucional de Amiloidosis del Hospital Italiano de Buenos Aires, entre enero de 2010 y noviembre de 2021. Se reportaron los valores de CLL entre trasplantes y al año del TCPH. Las variables cuantitativas se describieron como mediana e intervalo intercuartil, y las variables categóricas como frecuencias absolutas y relativas. Resultados: De 106 pacientes con amiloidosis AL, seis tuvieron TCO seguido de TCPH. La mediana de edad fue de 55 años. La mayoría eran hombres (n = 5). En el período entre trasplantes, la CLL involucrada disminuyó en dos pacientes y se mantuvo estable en tres. Todos lograron la remisión hematológica completa al año del TCPH. Un solo paciente presentó recaída en el órgano sólido trasplantado. Tacrolimus, micofenolato de mofetilo y corticoides fue el esquema inmunosupresor utilizado después del TCO. Conclusiones: El TCO representa una opción de tratamiento en pacientes con falla cardíaca grave por amiloidosis, permitiendo luego un tratamiento intensivo con quimioterapia de inducción y TCPH. Si bien faltan estudios, la terapia inmunosupresora después del TCO podría tener algún efecto sobre las células plasmáticas clonales.

Abstract Objective: To describe the evolution of serum free light chains (FLC) in the period between orthotopic heart transplantation (OHT) and autologous stem cell transplantation (ASCT), the hematological response one year after ASCT and chemotherapy and immunosuppressive treatment in patients with AL amyloidosis. Method: Case series of consecutive patients diagnosed with AL amyloidosis who received OHT followed by ASCT from the Institutional Registry of Amyloidosis of the Italian Hospital of Buenos Aires, between January 2010 and November 2021. FLC values between transplants and at year post ASCT. Quantitative variables were described with their median and interquartile range. Categorical variables as absolute and relative frequencies. Results: Of 106 patients with AL amyloidosis, 6 had an OHT followed by ASCT. The median age was 55 years. Most were men (n = 5). In the period between transplants, the involved CLL decreased in two patients and remained stable in three. All achieved complete hematologic remission 1 year after ASCT. A single patient presented relapse in the transplanted solid organ. Tacrolimus, mycophenolate mofetil, and corticosteroids were the immunosuppressive regimen used after OHT. Conclusions: OHT represents a treatment option in patients with severe heart failure due to amyloidosis, allowing later intensive treatment with induction chemotherapy and ASCT. Although studies are lacking, immunosuppressive therapy after OHT might have some effect on clonal plasma cells.

Abstract Introduction: In Mexico, cardiac rehabilitation (CR) as an interdisciplinary intervention with therapeutic impact in patients with heart disease is growing. There is the need to know actual conditions of CR in our country. Objectives: The objective of this National Registry is to follow-up those existing and new CR units in Mexico through the comparison between the two previous registries, RENAPREC-2009 and RENAPREC II-2015 studies. This is a descriptive study focused on diverse CR activities such as assistance training, and certification of health professionals, barriers, reference, population attended, interdisciplinarity, permanence over time, growth prospects, regulations, post-pandemic condition, integrative characteristics, and scientific research. Results: Data were collected from 45 CR centers in the 32 states, 75.5% are private practice units, 67% are new, 33% were part of RENAPREC II-2015, and 17 have continued since 2009. With a better distribution of CR units along the territory, the median reference of candidates for CR programs is 9% with a significant reduction into tiempo of enrollment to Phase II admission (19 ± 11 days). Regarding to previous registries, the coverance of Phases I, II, and III is 71%, 100%, and 93%, respectively; and a coverance increases in evaluation, risk stratification, and prescription, more comprehensive attendance and prevention strategies. Conclusions: CR in Mexico has grown in the past 7 years. Even there is still low reference and heterogeneity in specific processes, there are strengths such as interdisciplinarity, scientific professionalization of specialists, national diversification, and an official society that are consolidated over time.

ABSTRACT During the 2021/2022 soybean production season in Itapúa, Paraguay, the presence of Etiella zinckenella (Treitschke) caterpillars affecting soybean pods in the country was documented. The observations were made amidst a widespread drought that adversely affected soybean production. Caterpillars were collected from pods that exhibited signs of pest entry. Morphological characterization of the collected specimens matched the descriptions provided in taxonomic keys for E. zinckenella larvae. Molecular identification through DNA extraction and sequencing confirmed the identity of the pest as E. zinckenella, exhibiting a 96% similarity with known accessions of the species in the GenBank database. As a challenging pest to control, efforts should be directed towards evaluating the economic and damage thresholds caused by E. zinckenella, assessing resistance in soybean varieties used in Paraguay, and investigating the efficacy of biological and chemical insecticides. These findings can contribute to the development of integrated management strategies for effectively mitigating the impact of this pest on soybean production in Paraguay.

RESUMEN Durante la temporada de producción de soja 2021/2022 en la región de Itapúa, Paraguay, se documentó la presencia de orugas Etiella zinckenella (Treitschke) afectando las vainas de soja en el país. Las observaciones se realizaron en medio de una sequía generalizada que afectó negativamente a la producción de soja. Las orugas se recolectaron de las vainas que mostraban signos de entrada de plagas. La caracterización morfológica de los especímenes recolectados coincidió con las descripciones proporcionadas en claves taxonómicas para las larvas de E. zinckenella. La identificación molecular a través de la extracción y secuenciación de ADN confirmó la identidad de la plaga como E. zinckenella, exhibiendo un 96% de similitud con las accesiones conocidas de la especie en la base de datos GenBank. Como plaga difícil de controlar, los siguientes esfuerzos deben dirigirse a evaluar los umbrales económicos y de daño causados por E. zinckenella, evaluar la resistencia en las variedades de soja utilizadas en Paraguay e investigar la eficacia de los insecticidas biológicos y químicos. Estos hallazgos pueden contribuir al desarrollo de estrategias de manejo integrado para mitigar de manera efectiva el impacto de esta plaga en la producción de soja en Paraguay.

Abstract. The transformation of agricultural waste into activated carbon represents an attractive approach as new and alternative source, but also as a reduction of pollution associated to the degradation of precursors. The organic residues sugarcane (Saccharum officinarum) bagasse-shell, orange (Citrus sinensis) peel-bagasse, and eucalyptus (Eucalyptus globulus) leaves, obtained from a biodrying process were transformed into activated carbons using phosphoric acid as activating agent. The resulting materials were physicochemically characterized and after that, carbonaceous electrodes were prepared to test the feasibility of using them in a discoloration electro-Fenton wastewater treatment process. Orange peel-bagasse biodried precursor transformed into activated carbon showed the highest efficiency when used as the modifier in a carbon paste electrode due to its highest porosity, electroactive area (24.9x10-2 cm2), and roughness (1.21 a.u.), also to its chemical affinity for anionic molecules. These properties, in addition to the capability of electro-sorb iron ions on the surface during the Fenton reaction, allowed a 44 % methyl orange discoloration efficiency. Sugarcane bagasse-peel and eucalyptus leaves biodried residues were also evaluated with efficiencies under 30 %, mainly attributed to intrinsic composition of the precursor materials.

Resumen. La transformación de los residuos agrícolas en carbón activado representa un enfoque atractivo y novedoso, además de que representa una alternativa a la reducción de la contaminación asociada a la degradación de residuos orgánicos. Los residuos orgánicos de bagazo de caña de azúcar (Saccharum officinarum), bagazo y cáscara de naranja (Citrus sinensis), y hojas de eucalipto (Eucalyptus globulus), que fueron obtenidos de un proceso de biosecado, se transformaron en carbón activado utilizando ácido fosfórico como agente activante. Los materiales resultantes se caracterizaron fisicoquímicamente y después de eso, se prepararon electrodos de pasta de carbón modificados con estos materiales, para estudiar la viabilidad de utilizarlos en un proceso de tratamiento de aguas residualesmediante electro-Fenton. El precursor biosecado de bagazo y cáscara de naranja transformado en carbón activado mostró la mayor eficiencia cuando se usó como modificador en un electrodo de pasta de carbón, debido a su mayor porosidad, área electroactiva (24.9x10-2 cm2) y rugosidad (1.21), también debido a su mayor afinidad química por moléculas aniónicas. Estas propiedades, aunadas a la capacidad de electro-sorber iones de hierro en la superficie durante la reacción de Fenton, permitieron una eficiencia de decoloración del naranja de metilo del 44 %. También se evaluaron residuos biosecados de bagazo de caña de azúcar y hojas de eucalipto, con eficiencias inferiores al 30 %, atribuidas principalmente a la composición intrínseca de los materiales precursores.

A Atenção Primária à Saúde (APS) atende às necessidades individuais e coletivas da sua população adstrita. Dessa forma, considera-se que a equipe de saúde acolhe as mulheres, que sofreram violência. Contudo, os estudos mostram a fragilidade nos atendimentos a esse grupo. Nesse sentido, questiona-se, especificamente, a atuação dos enfermeiros. Eles são capazes de reconhecer, de maneira precoce, as usuárias do serviço de saúde, que sofrem, ou que correm risco de sofrer violência? Denunciariam a violência contra mulheres atendidas, na unidade de saúde? Existe um ditado, muito forte no Brasil, que diz: “em briga de marido e mulher, não se mete a colher”. Será que esta crença interfere nas ações dos enfermeiros da Atenção Primária à Saúde (APS)? Diante deste contexto, a pergunta desta investigação é: “Como o enfermeiro atua perante a violência contra a mulher na APS?” Objetivo: Identificar e sistematizar a atuação do enfermeiro perante a violência contra a mulher na APS. Método: Utilizou-se da Revisão Integrativa, buscando nas bases de dados LILACS e BDENF, no período entre 2011 a 2021, e nos idiomas inglês e português, artigos que respondiam à pergunta de pesquisa. Resultados: Os encaminhamentos para serviços especializados, serviço social e de psicologia, construção do vínculo, acolhimento e empatia são atuações promovidas pelos enfermeiros na APS. Considerações Finais: Considera-se que a revisão integrativa alcançou os objetivos propostos, uma vez que foi possível identificar e sistematizar a atuação do enfermeiro. Este profissional possui o papel de coordenador e, por sua vez, integrador da equipe. É importante que o mesmo elabore atividades de capacitação, atue com uma visão holística e multiprofissional, devido à alta complexidade da violência doméstica contra a mulher.

Primary Health Care (PHC) meets the individual and collective needs of its assigned population. Thus, it is considered that the health team welcomes women who have suffered violence. However, studies show the fragility of care for this group. In this sense, the role of nurses is specifically questioned. Are they able to recognize, at an early stage, users of the health service who suffer, or who are at risk of suffering violence? Would they denounce violence against women assisted at the health unit? There is a saying, very strong in Brazil, that says: "in a fight between husband and wife, don't get involved". Does this belief interfere with the actions of Primary Health Care (PHC) nurses? Given this context, the question of this investigation is: “How do nurses act in the face of violence against women in PHC?” Objective: To identify and systematize the role of nurses in the face of violence against women in PHC. Method: The Integrative Review was used, searching the LILACS and BDENF databases, in the period between 2011 and 2021, and in English and Portuguese, for articles that answered the research question. Results: Referrals to specialized services, social and psychological services, bond building, welcoming and empathy are actions promoted by nurses in PHC. Final Considerations: It is considered that the integrative review achieved the proposed objectives, since it was possible to identify and systematize the nurse's performance. This professional has the role of coordinator and, in turn, integrator of the team. It is important that he develop training activities, act with a holistic and multidisciplinary vision, due to the high complexity of domestic violence against women.

Resumen Objetivo: Determinar la eficacia de la procalcitonina (PCT) y la proteína C reactiva (PCR) séricas en el diagnóstico de fuga anastomótica (FA) en los pacientes sometidos a cirugía colorrectal. Método: Prueba diagnóstica en un hospital de tercer nivel. Se excluyeron los pacientes que no tuvieron mediciones preoperatorias de PCT y PCR. Se eliminaron los que cursaron con infección posoperatoria no relacionada con FA. Las medidas de eficacia diagnóstica fueron sensibilidad (S), especificidad (E), valores predictivos positivo (VPP) y negativo (VPN), razones de verosimilitud positiva (RV+) y negativa (RV−), y área bajo la curva característica operativa del receptor (AUROC). Resultados: Se analizaron 39 pacientes, de los cuales 6 (15.4%) tuvieron FA. La PCT y la PCR aumentaron al segundo día posoperatorio solo en los pacientes con FA. Los puntos de corte al día 2 fueron 1.55 ng/ml para PCT y 11.25 mg/l para PCR. La prueba más eficaz fue la PCR al día 2 (AUROC: 1.00; S: 100%; E: 96.7%; VPP: 85.7%; VPN: 100%; RV+: 33.0). Conclusiones: La PCR en el segundo día posoperatorio fue la prueba más eficaz en el diagnóstico temprano de FA en los pacientes sometidos a cirugía colorrectal, con un punto de corte inferior a lo reportado en la literatura internacional.

Abstract Objective: To determine the efficacy of serum procalcitonin (PCT) and C-reactive protein (CRP) in the early diagnosis of anastomotic leak (AL) in patients undergoing colorectal surgery. Method: Diagnostic test in a tertiary care hospital. Patients who did not have preoperative measurements of PCT and CRP were excluded. Those with postoperative infection not related to AL were eliminated. The diagnostic efficacy measures were sensitivity (Sn), specificity (Sp), positive (PPV) and negative (NPV) predictive values, positive (LR+) and negative (LR−) likelihood ratios, and area under the receiver operating characteristic curve (AUROC). Results: Thirty-nine patients were analyzed; six had AL (15.4%). PCT and CRP increased on the second postoperative day, only in patients with AL. The cut-off points at the second postoperative day were 1.55 ng/mL for PCT and 11.25 mg/L for CRP. The most efficacious test was PCR at second postoperative day (AUROC: 1.00; Sn: 100%; Sp: 96.7%; PPV: 85.7%; NPV: 100%; LR+: 33.0). Conclusions: CRP at second postoperative day was the most effective test in the early diagnosis of AL in patients undergoing colorectal surgery, with a cut-off point lower than that reported in the international literature.

ABSTRACT The post-pandemic COVID-19 effect reveals the need to strengthen Initial Teacher Education (ITE) in and from virtual environments. The present research is contextualized in a Higher Pedagogical Institute of Northern Lima in Peru. Its objective was to diagnose the current state of ITE and to identify factors that dynamize this training through educational virtualization to establish a proposal for improvement. A mixed methodological approach was deployed, with a concurrent design that allowed the application of a survey to 60 students (teachers in initial training) and 20 trainers of these future teachers; as well as a focus group with key informants: 6 students and 8 trainers. The results show the perception of a high level of ITE (86.7% high in students and 90% high in teachers). The qualitative content analysis revealed the following success factors of educational virtualization for initial teacher training: facilitating access to technology, online training and learning networks, articulation in the pedagogical teaching praxis; generating opportunities to reduce the digital divide; capitalization of learning; massification of digital transformation. Based on this, a model of educational virtualization is proposed, concretized in a practical way in an educational strategy to develop initial teacher training.

Resumen La vertiente oriental de las Cumbres Calchaquíes, en la provincia de Tucumán, es un área donde se expandieron amplias y complejas ocupaciones humanas que dieron forma a paisajes aldeanos tempranos. Su estudio arqueológico se ha caracterizado por un heterogéneo conoci miento de distintas localidades. En este trabajo se presentan los resultados de investigaciones realizadas por nuestro equipo desde el año 2014, abordando en clave comparativa las configu raciones materiales de la cuenca de Anfama y el valle de La Ciénega, datadas entre los siglos I y VII d.C. El objetivo principal es realizar una síntesis de las investigaciones llevadas a cabo hasta el momento y definir similitudes y particularidades en las maneras de habitar que desarrollaron las poblaciones de los sectores estudiados. Principalmente se analizan tres ejes articuladores: características generales de los paisajes, estructuración de los espacios domésticos y temporalidad.

ABSTRACT The eastern slopes of the Cumbres Calchaquíes, in the province of Tucumán, is an area where large and complex human occupations have expanded rising early villager landscapes. Their archaeological research has been characterized by a heterogeneous knowledge of diffe- rent localities. This paper presents the results of research carried out by our team since 2014, addressing in comparative key the material configurations of the Anfama basin and the valley of La Ciénega, dating between the 1st and 7th century A.D. The main objective is to synthesize the researches carried out so far, in order to determine similarities and particularities of the ways of living developed by the populations of the studied sectors. We mainly address three articulating axes: general characteristics of the landscapes, structuring of domestic spaces, and temporality.

Resumen Términos como “parásitos”, “patógenos” o “virus” se utilizan en el campo de la medicina para la identificación de organismos que producen daño sobre otros. Sin embargo, en el campo de la veterinaria y su interacción con la ecología el contexto es diferente: la utilización indiscriminada de estos términos ha producido que muchas veces los mismos se utilicen como sinónimos. Al estudiar la bibliografía disponible sobre apicultura o conservación de abejas nativas, podemos observar que solamente unos pocos y recientes estudios se focalizan en esta necesaria reconceptualización de los términos basada en la ecología. A lo largo de esta revisión buscaremos diferenciar los conceptos de “parásito”, “patógeno” y“virus”, y redefinir los conceptos de “virulencia” y “patogenicidad” bajo un contexto ecológico. Esta revisión, propone demostrar que las interacciones parásito/hospedador pueden expresarse de forma diferencial en función del contexto micro (hospedador) y macro ambiental (ambiente del hospedador). Aunque utilizaremos a las abejas melíferas (Apis mellifera) como modelo, la teoría aquí abordada podría ser extrapolada por el lector a otros sistemas parasitarios.

Abstract Parasitism and bees: a concept revision from an ecological perspective. From the beginning all, parasites, pathogens and viruses are organisms that have a negative connotation in the field of medicine. However, the use of methodologies and terms of medicine in the field of ecology and, above all, veterinary medicine, led to this understanding of "pathogenic" organisms reaching such studies. When we look into the apicultural research bibliography, we find that these concepts sometimes are poorly distinguished and only a few early studies have been focused on bringing light on this conflictive conceptualization. Today we find a large number of scientific articles that misuse these terms and often consider them as synonyms. Throughout this review we will seek to differentiate each of these terms and generate consensus that avoids the confusion of such important ecological concepts.

RESUMEN: Se informa sobre la presencia de un afloramiento de obsidiana negra previamente desconocido ubicado en el extremo oriental del Macizo del Deseado, en cercanías del océano Atlántico y de la localidad de Tres Cerros, en Patagonia. La obsidiana constituye un vidrio de riolita subalcalina con contenido medio de potasio. Es de menor calidad que la obsidiana negra de la fuente de Pampa del Asador, emplazada en inmediaciones de la cabecera del río Chico, en el noroeste de Santa Cruz. Los datos geoquímicos de ICP-MS e INAA obtenidos para 16 muestras de obsidiana son comparables cuando se consideran las incertidumbres de medición. Sin embargo, éstos son significativamente diferentes a los datos de ICP-MS publicados para muestras procedentes de Pampa del Asador y 17 de Marzo, lo que indica que la obsidiana de Tres Cerros se puede diferenciar geoquímicamente de las mencionadas fuentes secundarias. Se analizó un artefacto de obsidiana negra procedente del sitio Alero 4, ubicado en la costa noreste de Santa Cruz, que presentaba características macroscópicas similares a las identificadas en las muestras de Tres Cerros. Los resultados indicaron que se trataba de una obsidiana procedente de Pampa del Asador. Asimismo, las tendencias geoquímicas obtenidas para las muestras de Tres Cerros no resultaron compatibles con las observadas en artefactos de los sitios Alero del Valle y Cueva Aristizábal, emplazados próximos a la costa sudeste de Santa Cruz. En este sentido, si bien aún no se han registrado evidencias que indiquen la explotación de la fuente Tres Cerros por parte de grupos humanos cazadores-recolectores que ocuparon Patagonia en el pasado, la caracterización geoquímica aquí presentada constituye información que podrá ser comparada con muestras procedentes de sitios arqueológicos ubicados a distintas distancias de ella, contribuyendo de esta manera a entender la movilidad humana en la región, así como los criterios de selección de materias primas.

ABSTRACT: We report a previously unknown black obsidian outcrop located at the eastern end of the Deseado Massif, near the Atlantic Ocean and the town of Tres Cerros, in Patagonia. This obsidian is a subalkaline rhyolite glass with medium potassium content. It is of lower quality than the black obsidian from the Pampa del Asador source, located in the vicinity of the headwaters of the Chico River, in the northwest of Santa Cruz. The ICP-MS and INAA geochemical data obtained for 16 obsidian samples are comparable when measurement uncertainties are considered. However, these are significantly different from published ICP-MS data for samples from Pampa del Asador and 17 de Marzo, indicating that obsidian from Tres Cerros can be differentiated geochemically from these secondary sources. A black obsidian artifact from the Alero 4 site, located on the northeastern coast of Santa Cruz, was analyzed, showing macroscopic characteristics similar to those identified in the Tres Cerros samples. The results indicated that it was an obsidian from Pampa del Asador. Likewise, the geochemical trends obtained for the Tres Cerros samples were not compatible with those observed in artifacts from the Alero del Valle and Cueva Aristizábal sites, located close to the southeast coast of Santa Cruz. In this sense, we emphasize that no evidence has yet been recorded that indicates the exploitation of Tres Cerros source by human hunter-gatherer groups that occupied the Patagonian region in the past. In this framework, the geochemical characterization of the potential source presented here constitutes initial information which can be compared with the one obtained from artifacts in archaeological sites, providing information to understand human mobility and the criteria for raw material selection.

Abstract Background Skeletal muscle is sensitive to bile acids (BA) because it expresses the TGR5 receptor for BA. Cholic (CA) and deoxycholic (DCA) acids induce a sarcopenia-like phenotype through TGR5-dependent mechanisms. Besides, a mouse model of cholestasis-induced sarcopenia was characterised by increased levels of serum BA and muscle weakness, alterations that are dependent on TGR5 expression. Mitochondrial alterations, such as decreased mitochondrial potential and oxygen consumption rate (OCR), increased mitochondrial reactive oxygen species (mtROS) and unbalanced biogenesis and mitophagy, have not been studied in BA-induced sarcopenia. Methods We evaluated the effects of DCA and CA on mitochondrial alterations in C2C12 myotubes and a mouse model of cholestasis-induced sarcopenia. We measured mitochondrial mass by TOM20 levels and mitochondrial DNA; ultrastructural alterations by transmission electronic microscopy; mitochondrial biogenesis by PGC-1α plasmid reporter activity and protein levels by western blot analysis; mitophagy by the co-localisation of the MitoTracker and LysoTracker fluorescent probes; mitochondrial potential by detecting the TMRE probe signal; protein levels of OXPHOS complexes and LC3B by western blot analysis; OCR by Seahorse measures; and mtROS by MitoSOX probe signals. Results DCA and CA caused a reduction in mitochondrial mass and decreased mitochondrial biogenesis. Interestingly, DCA and CA increased LC3II/LC3I ratio and decreased autophagic flux concordant with raised mitophagosome-like structures. In addition, DCA and CA decreased mitochondrial potential and reduced protein levels in OXPHOS complexes I and II. The results also demonstrated that DCA and CA decreased basal, ATP-linked, FCCP-induced maximal respiration and spare OCR. DCA and CA also reduced the number of cristae. In addition, DCA and CA increased the mtROS. In mice with cholestasis-induced sarcopenia, TOM20, OXPHOS complexes I, II and III, and OCR were diminished. Interestingly, the OCR and OXPHOS complexes were correlated with muscle strength and bile acid levels. Conclusion Our results showed that DCA and CA decreased mitochondrial mass, possibly by reducing mitochondrial biogenesis, which affects mitochondrial function, thereby altering potential OCR and mtROS generation. Some mitochondrial alterations were also observed in a mouse model of cholestasis-induced sarcopenia characterised by increased levels of BA, such as DCA and CA.

Abstract Pygocentrus nattereri is a widely distributed species in the Neotropical region and a potential bio-indicator. Kidneys have functions in fish physiology, allowing them to live in different environments. We aimed to compare the histological characteristics of caudal kidneys between males and females, associating them with the renosomatic index (RSI). For this purpose, 15 males and 14 females were used for biometric and histological analyses. Structural volumetric density (SVD), renal corpuscle histometric measures, and hemosiderin and lipofuscin deposit frequency in macrophages melanogenic (MMs) were assessed. No biometric differences were observed between the sexes, but body weight and standard length were correlated with RSI. The SVD showed difference in hematopoietic tissue between female and males, whereas the density of the other structures was not different. The RSI was positively associated with hematopoietic tissue and proximal tubule density in contrast to distal tubules, blood vessels, collecting ducts and MMs. Females exhibited a higher renal corpuscle area, glomerulus area, distal tubule diameter, collecting tubule area, and collecting tubule lumen area. These differences may be due to metabolic differences between males and females. Sex effect in P. nattereri may define punctual differences in future studies on the metabolism and immunity of this species.

Resumo Pygocentrus nattereri é uma espécie amplamente distribuída na região Neotropical e pode ser considerada como um potencial bioindicador ambiental. Os rins têm funções cruciais na fisiologia dos peixes, permitindo-lhes viver em diferentes ambientes. Nosso objetivo foi comparar as características histológicas dos rins excretores entre machos e fêmeas, associando-as ao índice renossomático (IRS). Para tanto, 15 machos e 14 fêmeas foram utilizados para análises biométricas e histológicas. Amostras do tecido renal foram processadas para densidade estrutural volumétrica, medidas histométricas do corpúsculo renal e frequência dos depósitos de hemossiderina e lipofuscina nos macrófagos melonogênicos (MMs). Não foram observadas diferenças biométricas entre os sexos, mas a massa corporal e o comprimento padrão foram correlacionados com IRS. Apenas a densidade estrutural volumétrica do tecido hematopoiético foi diferente entre machos e fêmeas. Não houve diferença nas demais estruturas. O IRS associou-se positivamente com o tecido hematopoiético e densidade dos túbulos proximais e negativamente com os túbulos distais, vasos sanguíneos, ductos coletores e MMs. As fêmeas apresentaram maior área do corpúsculo renal, área do glomérulo, diâmetro do túbulo distal, área do túbulo coletor e área do lúmen do túbulo coletor. Essas diferenças podem ser devida às diferenças metabólicas entre machos e fêmeas. Particularidade do efeito de sexo em P. nattereri pode definir diferenças pontuais em futuros estudos sobre o metabolismo e imunidade nesta espécie.
