ProBiota | Serie Técnica y Didáctica | Lista de peces de la provincia de Entre Ríos

La provincia de Entre Ríos, con una superficie de 78.781 km2, cuenta con una red hidrográfica intrincada, conformada por ríos y arroyos que surcan el territorio provincial en todas direcciones. La particular morfología del terreno, una llanura con suaves ondulaciones que no superan los 100 metros de altura, permite diferenciar cuatro vertientes en suelo entrerriano: Oeste o del Paraná, Central o del Gualeguay, Este o del Uruguay y Meridional, al sur de Diamante. Estas vertientes comprenden doce cuencas hidrográficas, tributarias de los dos grandes cursos que limitan la provincia, el río Paraná, al oeste y el río Uruguay, al este. Esta provincia se halla dentro del área de mayor diversidad ictiofaunística de la Argentina (López et al., 2005); ubicándose dentro de la provincia Párano-Platense (Ringuelet, 1975) o la provincia de los Grandes Ríos (López et al., 2008). Esta región cuenta con una amplia heterogeneidad ambiental que incide positivamente sobre la riqueza específica, así como en la morfología, fisiología y el comportamiento de los peces (Bonetto, 1986; Rossi et al., 2007). Los antecedentes existentes son referidos a la composición íctica del río Paraná medio y su llanura aluvial o del río Uruguay medio e inferior (ver López et al., 2006). Las cuencas interiores de la provincia de Entre Ríos han sido escasamente estudiadas y la mayoría de los trabajos se refieren a tributarios del río Uruguay y en menor medida para tributarios del Paraná. En los trabajos de síntesis de López et al. (2005); Demonte & Arias (2005) y Aceñolaza et al. (2008), se analizó la información disponible generando listas comentadas de la ictiofauna entrerriana. Ésto ha determinado que, en los últimos años el número de especies citadas para Entre Ríos se haya incrementado considerablemente. El objetivo de este trabajo es actualizar, a partir de datos propios y bibliográficos, la distribución de las especies dentro del territorio provincial dando como resultado una lista ictiofaunistíca.Facultad de Ciencias Naturales y Muse

Hacia un control inmunológico de la toxocariasis: inmunoprotección en canes con antígenos de Toxocara canis

Tanto en perros como en seres humanos la toxocariasis se controla con el uso de drogas antiparasitarias. Su continuo uso produce resistencia en el hospedero. El perro es fundamental en la contaminación del ambiente con huevos de Toxocara canis y posterior transmisión accidental de ellos al hombre. Interrumpir la cadena epidemiológica de transmisión es primordial. En este ensayo preliminar se investigó la inmunoprotección en canes con antígenos de T. canis. Se inocularon cinco perros: dos (una hembra y un macho) con antígenos de excreción-secreción, dos hembras con antígenos escondidos y un macho destinado como control. A los 15 días de la segunda dosis, todos los animales fueron infectados con 500 huevos larvados de T. canis. A los 25 días los perros fueron desparasitados, registrándose la carga parasitaria como indicador de efectividad de la inoculación. Todos mostraron huevos en el día 25 post desafío y la posterior negativización a los 20 días en los inmunizados. En el perro control, la cantidad de huevos fue mayor en el día 25 post desafío que en los animales del grupo experimental y aumentó aún más en los días posteriores. Estos resultados iniciales permiten estimular los estudios de selección de antígenos e inmunoprotección con miras a la obtención de un sistema vacunal para canes. La bibliografía internacional no muestra experiencias similares en la unidad T. canis-perro

Prognostic Molecular Biomarkers in Chordomas: A Systematic Review and Identification of Clinically Usable Biomarker Panels

INTRODUCTION AND OBJECTIVE: Despite the improvements in management and treatment of chordomas over time, the risk of disease recurrence remains high. Consequently, there is a push to develop effective systemic therapeutics for newly diagnosed and recurrent disease. In order to tailor treatment for individual chordoma patients and develop effective surveillance strategies, suitable clinical biomarkers need to be identified. The objective of this study was to systematically review all prognostic biomarkers for chordomas reported to date in order to classify them according to localization, study design and statistical analysis. METHODS: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we systematically reviewed published studies reporting biomarkers that correlated with clinical outcomes. We included time-to-event studies that evaluated biomarkers in skull base or spine chordomas. To be included in our review, the study must have analyzed the outcomes with univariate and/or multivariate methods (log-rank test or a Cox-regression model). RESULTS: We included 68 studies, of which only 5 were prospective studies. Overall, 103 biomarkers were analyzed in 3183 patients. According to FDA classification, 85 were molecular biomarkers (82.5%) mainly located in nucleus and cytoplasm (48% and 27%, respectively). Thirty-four studies analyzed biomarkers with Cox-regression model. Within these studies, 32 biomarkers (31%) and 22 biomarkers (21%) were independent prognostic factors for PFS and OS, respectively. CONCLUSION: Our analysis identified a list of 13 biomarkers correlating with tumor control rates and survival. The future point will be gathering all these results to guide the clinical validation for a chordoma biomarker panel. Our identified biomarkers have strengths and weaknesses according to FDA\u27s guidelines, some are affordable, have a low-invasive collection method and can be easily measured in any health care setting (RDW and D-dimer), but others molecular biomarkers need specialized assay techniques (microRNAs, PD-1 pathway markers, CDKs and somatic chromosome deletions were more chordoma-specific). A focused list of biomarkers that correlate with local recurrence, metastatic spread and survival might be a cornerstone to determine the need of adjuvant therapies

Mollusk allergy in shrimp-allergic patients: Still a complex diagnosis. An Italian real-life cross-sectional multicenter study

Introduction: Shellfish allergy is an important cause of food allergies worldwide. Both in vivo and in vitro diagnostics failure nowadays is caused by the poor quality of the extracts associated with the scarce availability of allergenic molecules in the market. It is known that not all patients with shellfish allergies experience adverse reactions to mollusks. It is still unclear how to detect and diagnose these patients correctly.Aim: To investigate the features of shrimp-allergic patients either reactive or tolerant to mollusks, with the currently available diagnostic methods.Methods: Nineteen centers, scattered throughout Italy, participated in the real-life study, enrolling patients allergic to shrimp with or without associated reactions to mollusks. Patients underwent skin tests using commercial extracts or fresh raw and cooked shrimp and mollusks, and IgE reactivity to currently available allergenic extracts and molecules was measured in vitro.Results: Two hundred and forty-seven individuals with a self reported adverse reactions to shrimp participated in the study; of these 47.8% reported an adverse reaction to mollusks ingestion (cephalopod and/or bivalve). Neither of the tests used, in vivo nor in vitro, was able to detect all selected patients. Accordingly, a great heterogeneity of results was observed: in vivo and in vitro tests agreed in 52% and 62% of cases. Skin tests were able to identify the mollusk reactors (p < 0.001), also using fresh cooked or raw food (p < 0.001). The reactivity profile of mollusk reactors was dominated by Pen m 1, over Pen m 2 and Pen m 4 compared to tolerant subjects, but 33% of patients were not detected by any of the available molecules. Overall, a higher frequency of IgE rectivity to shrimp was recorded in northern Italy, while mollusk reactivity was more frequent in the center-south.Conclusion: The current diagnostic methods are inadequate to predict the cross-reactivity between crustaceans and mollusks. The detection of mollusks hypersensitivity should still rely on skin tests with fresh material. The exclusion of mollusks from shrimp allergic patients' diets should occur when clinical history, available diagnostic instruments, and/or tolerance tests support such a decision

FACT-MNG: tumor site specific web-based outcome instrument for meningioma patients

To formulate Functional Assessment of Cancer Therapy-Meningioma (FACT-MNG), a web-based tumor site-specific outcome instrument for assessing intracranial meningioma patients following surgical resection or stereotactic radiosurgery. We surveyed the relevant literature available on intracranial meningioma surgery and subsequent outcomes (38 papers), making note of which, if any, QOL/outcome instruments were utilized. None of the surgveyed papers included QOL assessment specific to tumor site. We subsequently developed questions that were relevant to the signs and symptoms that characterize each of 11 intracranial meningioma sites, and incorporated them into a modified combination of the Functional Assessment of Cancer Therapy-Brain (FACT-BR) and SF36 outcome instruments, thereby creating a new tumor site-specific outcome instrument, FACT-MNG. With outcomes analysis of surgical and radiosurgical treatments becoming more important, measures of the adequacy and success of treatment are needed. FACT-MNG represents a first effort to formalize such an instrument for meningioma patients. Questions specific to tumor site will allow surgeons to better assess specific quality of life issues not addressed in the past by more general questionnaires

A Low Dimensional Description of Globally Coupled Heterogeneous Neural Networks of Excitatory and Inhibitory Neurons

Neural networks consisting of globally coupled excitatory and inhibitory nonidentical neurons may exhibit a complex dynamic behavior including synchronization, multiclustered solutions in phase space, and oscillator death. We investigate the conditions under which these behaviors occur in a multidimensional parametric space defined by the connectivity strengths and dispersion of the neuronal membrane excitability. Using mode decomposition techniques, we further derive analytically a low dimensional description of the neural population dynamics and show that the various dynamic behaviors of the entire network can be well reproduced by this reduced system. Examples of networks of FitzHugh-Nagumo and Hindmarsh-Rose neurons are discussed in detail

Monitoreo de glifosato en agua superficial en Entre Ríos: La investigación acción participativa como metodología de abordaje

Las pérdidas de glifosato desde agroecosistemas y su impacto sobre el agua superficial generan preocupación en los actores de la comunidad rural y urbana de Entre Ríos, habiéndose generalizado percepciones de riesgo. La ausencia de información ha agudizado la sensibilidad social, requiriéndose un abordaje adecuado. Los objetivos fueron: conformar una red de monitoreo del efecto del uso de glifosato sobre la calidad del agua (RMCA) en el área agrícola de Entre Ríos; estimar la concentración de glifosato en agua superficial, y acordar prácticas agronómicas de bajo impacto ambiental. Se desarrolló una investigación acción participativa (IAP), con participación de diferentes actores en todas las instancias del estudio. Se llevó adelante un programa de sensibilización de profesionales, productores y organismos interesados en conocer la calidad de aguas. La selección de sitios y el muestreo fueron realizados por los integrantes de la RMCA. Se establecieron tres períodos de muestreo: 1.°: 15 agosto – 15 setiembre 2012; 2.°: 15 noviembre – 15 diciembre 2012, y 3.°: 15 marzo – 15 abril 2013. Las concentraciones de glifosato fueron clasificadas en 3 categorías: <0,1 μg L-1; 0,1-240 μg L-1 y ˃240 μgL-1. La RMCA resultó integrada por 70 miembros. Se evaluaron 311 puntos y 703 muestras de agua. En el primer período, 4,7% de los puntos superó el nivel de 240 μgL-1, mientras que en el segundo todas las concentraciones resultaron inferiores, de las cuales un 69,2% presentó valores inferiores a 0,1 μg L-1. El 76% de las muestras de marzo/abril presentó concentraciones inferiores a 0,1 μg L-1. Los resultados se discutieron con los integrantes de la RMCA en un taller replicado en cuatro localidades y en un segundo evento se acordaron prácticas agronómicas de bajo impacto ambiental. La IAP demostró ser una metodología adecuada para analizar los cambios en la calidad del agua superficial debidos al uso de glifosato en Entre Ríos. La cuantificación de la concentración de glifosato permitió analizar el riesgo de contaminación no medido precedentemente, lo cual fue motor de búsqueda de soluciones consensuadas entre los diferentes actores del sector agroalimentario para mitigar o remediar impactos ambientales por el uso de agroquímicos.There is concern about glyphosate losses from agroecosystems and its impact on surface water in urban and rural communities of Entre Rios, having a widespread perception of risk in public opinion. Social awareness was exacerbated by lack of information, which requires an adequate approach. The objectives were: i) to set up a network for monitoring the effect of glyphosate use on water quality (RMCA) in the agricultural area of Entre Rios, ii) to estimate glyphosate concentration in surface water as a result of losses from the agroecosystem, and iii) to identify management practices of low environmental impact to be agreed on with members of the agro alimentary sector. The methodological framework applied corresponds to a Participatory Action Research (PAR) approach. An awareness program for professionals, farmers and organizations interested in knowing water quality was carried out. Site selection and water sampling were carried out by RMCA members. A schedule of 3 sampling periods was established: 1º) August 15th - September 15th 2012, 2º) November 15th - December 15th 2012 and 3º) March 15th - April 15th 2013. Concentration of glyphosate in the water samples was determined by the Elisa technique, using as a UPLC-MS/MS verification method. Glyphosate concentrations were classified according to the guide levels defined by the Undersecreatriat of Water Resources of Argentina and the European Union: < 0.1 µg L-1; 0.1-240 µg L-1 y ˃ 240 µg L-1. The RMCA network was integrated by 70 members becoming a community-based organization to promote the preservation of surface water. 311 monitoring points and 703 water samples were evaluated. In the first period, 4.7% of the monitoring points overcame the level of 240 µg L-1 whereas in the second sampling instance all concentrations results were lower, 69% of them showing values below 0.1 µg L-1. 76% of the March-April samples resulted in concentrations below 0.1 µg L-1. Results were discussed by RCMA members in a workshop that was replicated at 4 locations. In a second meeting, the members identified on agronomic practices of environmental low impact. The PAR proved to be an adequate methodology to analyze changes in the quality of surface water due to the use of glyphosate in the agricultural area of Entre Rios. The quantification of glyphosate concentration in water allowed to know the risk of pollution, not previously measured, which promoted the search for consensual solutions among stakeholders of the agro alimentary sector to either mitigate or solve environmental impact by the use of agrochemicals.Fil: Sasal, Maria Carolina.
