Weight gain as a potential risk factor in kidney stones formers Moyano, Mario Franco; Wendel, Graciela Haydée; Trujillo, Liliana del Carmen; Orellano, Guillermo Osvaldo; Fuentes, Lucia Beatriz The prevalence of kidney stones is increasing and obesity has reaching epidemic proportions. The aim was to investigate whether obesity influences the kidney stone forming. 421 patients, 31.6% women and 41.6% men were overweight (OV), and 25% and 9.6% were obese (OB), respectively. Serum uric acid increased significantly OB women(p<0.001), differences between gender(p<0.001). Creatinine increased in OB men(p<0.05), and men respect to women(p < 0.001), urea between OB women and men(p<0.05). PTH increased in OB women(p<0.05). Urinary excretion phosphorus(p<0.05), uric acid(p<0.01) increased in OB women. Creatinine clearance was higher in OB both sexes(p<0.05), and differences compared women to men(p<0.001). BMI was positively correlated with serum uric acid, sodium, potassium and PTH in both sexes and urinary uric acid excretion, calcium, sodium, phosphate in women and oxalic acid in both sexes. Glomerular filtration rate, urine specific gravity and pH were inversely related to BMI. Uric acid is main stone constituent in obese women(86.36%) and overweight men(86.66%). In conclusion, higher body weight could be associated with an increased risk of renal stone forming and some metabolic gender differences were found.

El concepto de responsabilidad como clave de lectura de Los orígenes del Totalitarismo; The notion of responsibility as a key to the origins of totalitarianism Cantero, María de Los Angeles El concepto de responsabilidad atraviesa centralmente el pensamiento de Arendt, por lo que resulta pertinente asumirlo como clave de lectura de sus textos. En el presente artículo esta perspectiva de análisis se focaliza en Los orígenes del totalitarismo . Considerando que el totalitarismo es un régimen de dominación total que elimina la responsabilidad, en este trabajo se utiliza el descubrimiento por contraste, es decir, el camino del reconocimiento del significado –por así decirlo– “positivo” de la responsabilidad, mediante el análisis de todas las formas empleadas por el totalitarismo para escapar de ella y abolirla. Para mostrar el recorrido que va desde la evasión hasta la abolición de la responsabilidad, en primer lugar se presentan las teorías y las formas de escape de la responsabilidad. Luego se consideran dos puntos prominentes del camino recorrido por el totalitarismo para imponer un modelo de hombre cuyo centro es la abolición de la responsabilidad: a ) la ruptura con la realidad y la abolición de la capacidad de pensar, y b ) el principio “todo es posible” y la supresión de la idea de humanidad. Por último, se exponen las conclusiones acerca del concepto de responsabilidad.; The concept of responsibility centrally transverses Arendt’s thought, which makes it pertinent to assume it as key to the reading of her texts. In the present article this analytical perspective focuses in The Origins of Totalitarianism. Considering that totalitarianism is a regime of total domination that eliminates responsibility, this task makes use of discovery by contrast, that is, a way to recognize the –so to say– “positive” meaning of responsibility, by means of the analysis of every form used by totalitarianism to escape it and abolish it. To show the haul from the evasion to the abolition of responsibility, the theories and the forms of escape from responsibility are presented in the first place. Then, there will be a consideration for two prominent points of the way trodden by totalitarianism to impose a model of man whose center is the abolition of responsibility: a) the rupture with reality and the abolition of the capacity for thought, and b) the principle that “everything is possible” and the suppression of the idea of humanity. Last, some conclusions about the concept of responsibility.

Inequality, joint participation and (re) distributive challenges in the Argentina Republic Rezzoagli, Luciano Carlos; Gamberg, Guillermina The fiscal correspondence and a giving - back vision of fiscal and financial relationships between different scalar spheres is valid and adequate when the competence features are similar between subnational entities. But, in a clear situation of regional asymmetry (many Argentinas within the same Argentina), in a country that belongs to the most unequal continent in the World, this vision threatens the possibility of citizens living peripheral areas to enforce their constitutional rights and enable their development.The constitutional reform from 1994 incorporated among its multiple changes and additions, a substantial innovation in terms of fiscal federalism: the privileged hierarchization of the federal revenue sharing regime. In this way, the constitutional principles and purposes that may develop from the financial and tax field were consolidated. The principles of regional harmonious prosperity and equal human development acquired special emphasis in the spirit of the preexisting joint participation regime. Moreover, in the sixth transitional clause they established an express mandate to reelaborate the then current regime. The distance between the constitution and the fiscal reality becomes insurmountable until there exists a clarifying position regarding the ambiguity of the dominant discourses about fiscal decentralization that tend to consolidate the weakness of the state institutions in the country, and the growth of the regional asymmetries with their respective populational migration flow towards the cities with greater resources and/or their peripheries.

Mixed spatially varying L2-BV regularization of inverse ill-posed problems Mazzieri, Gisela Luciana; Spies, Ruben Daniel; Temperini, Karina Guadalupe Several generalizations of the traditional Tikhonov-Phillips regularization method have been proposed during the last two decades. Many of these generalizations are based upon inducing stability throughout the use of different penalizers which allow the capturing of diverse properties of the exact solution (e.g. edges, discontinuities, borders, etc.). However, in some problems in which it is known that the regularity of the exact solution is heterogeneous and/or anisotropic, it is reasonable to think that a much better option could be the simultaneous use of two or more penalizers of different nature. Such is the case, for instance, in some image restoration problems in which preservation of edges, borders or discontinuities is an important matter. In this work we present some results on the simultaneous use of penalizers of L2 and of bounded variation (BV) type. For particular cases, existence and uniqueness results are proved. Open problems are discussed and results to signal restoration problems are presented.

¿Qué saben sobre plantas empleadas en medicina tradicional los niños de una escuela primaria de S. S. de Jujuy, Argentina?; O que sabem sobre plantas empregadas na medicina tradicional as crianças de uma escola primária de S. S. de Jujuy, Argentina?; What do children in a primary school in San Salvador de Jujuy, Argentina, know about plants used in traditional medicine? Acosta, Marina Eva; Vignale, Nilda Dora; Ladio, Ana Haydee Este trabajo muestra resultados preliminares de un taller realizado con los alumnos de 7mo grado de la Escuela Primaria Nro. 190 “Dr. Macedonio Graz” que provienen de familias inmigrantes bolivianas y que habitan en la ciudad de S.S. de Jujuy. Se indagó sobre el conocimiento botánico relacionado al uso de especies medicinales y las formas de adquisición-transmisión de ese conocimiento, así como también el rol que cumple la institución educativa como espacio de apertura a temas vinculados a la realidad local. Se emplearon técnicas propias de la metodología participativa que se utiliza en la indagación etnobotánica. Los datos se analizaron cualitativamente. Los resultados arrojaron 42 especies con fines medicinales siendo la especie de mayor frecuencia de uso Ruta sp. “ruda” (67%). Las familias botánicas más representativas fueron Asteraceae (20%) y Lamiaceae (17%). Los órganos vegetales más usados fueron las hojas (54%) y la dolencia más común tratada con estas especies fue para el dolor de estómago” (25%). Se distinguieron tres formas de aprovisionamiento de plantas (campo, casa, comercio) siendo el campo (49%) el ambiente más frecuente. El modo más significativo de transmisión de este conocimiento fue a través de los abuelos (29%).Se pudo revalorizar el uso de las plantas medicinales que aún sigue vigente en los alumnos, contribuyendo a la generación de conciencia colectiva sobre la importancia de la conservación de los saberes como parte de la identidad local que se construye y se mantiene a través de generaciones.; Este trabalho mostra resultados preliminares de um workshop realizado com os alunos da 7ª série da Escola Primária Nro. 190 ?Dr. Macedonio Graz?, que provêm de famílias bolivianas imigrantes que moram na cidade de S. S. de Jujuy. Indagou-se sobre o conhecimento botânico relacionado com a utilização de espécies medicinais e as formas de aquisição e transmissão desse conhecimento, assim como também o papel desempenhado pela instituição de ensino como espaço aberto para as questões relacionadas com a realidade local. Empregaram-se técnicas próprias da metodologia participativa que se utiliza na indagação etnobotânica. Os dados se analisaram qualitativamente. Os resultados mostraram 42 espécies com fins medicinais, sendo a espécie de maior frequência de uso a Ruta sp. ?arruda? (67%). As famílias botânicas mais representativas foram Asteraceae (20%) e Lamiaceae (17%). Os órgãos vegetais mais usados foram as folhas (54%) e a doença mais comum tratada com estas espécies foi ?dor de barriga? (25%). Diferenciaram-se três formas de abastecimento de plantas (campo, casa, comércio) sendo o campo (49%) o ambiente mais frequente. O modo mais significativo de transmissão deste conhecimento foram os avôs (29%). Pôde-se revalorizar o uso das plantas medicinais que ainda continua vigente nos alunos, contribuindo à geração de consciência coletiva sobre a importância da conservação dos saberes como parte da identidade local que se constrói e se mantêm através das gerações.; This work reports on the preliminary results of a workshop carried out with 7th form pupils from primary school no. 190 “Dr. Macedonio Graz”. The children belong to immigrant Bolivian families living in the city of S.S. de Jujuy. Their botanical knowledge related to the use of medicinal species and methods of acquisition and transmission of this knowledge were analysed. In addition, the role played by the educational institution was evaluated in terms of providing opportunities for the development of topics associated with the reality of locals’ lives. Techniques from the participatory methodology commonly used in ethnobotanical studies were used, and the data obtained were analysed qualitatively. Results revealed 42 species used for medicinal purposes, the species with the highest use frequency being Ruta sp. “ruda” (67%). The most represented families were Asteraceae (20%) and Lamiaceae (17%). The most frequently used plant organs were leaves (54%) and the most commonly treated health complaint with these species was “stomach pain” (25%). Three ways of obtaining the plants were identified (countryside, home, commercial outlets), the countryside being the most common source of the three. The most important means of transmission of this knowledge was grandparents (29%). The value of medicinal plant use, a practice still in effect today in the daily lives of these pupils, was reinforced contributing to the creation of a collective conscience about the importance of conserving this wisdom as partof the local identity which is constructed and maintained over generations.

Judicialización de la política y soberanía popular: sobre el estatuto político de las resoluciones judiciales; Judicialization of politics and popular sovereignty: On the political status of judicial resolutions; Judiciarisation de la politique et souveraineté populaire: sur le statut politique des résolutions judiciaires Alvarez, Luciana Nuestro trabajo se ocupa de la judicialización de la política en las sociedades democráticas contemporáneas en cuanto fenómeno que podría haber incidido en las formas en que se ejerce la soberanía popular y, más precisamente, en los modos en que es dable pensar los procesos políticos emancipatorios. En este sentido, y a partir de una consideración específica tanto del “pueblo” como de “lo político”, nos interesará problematizar las distintas interpretaciones (visión crítica y visión encantada) en torno de la judicialización de la política. Finalmente, nuestra indagación se pregunta por la posibilidad de explorar la potencialidad político -emancipatoria de las disputas judiciales.; The subject of this paper is the judicialization of politics in democratic contemporary societies, which is a phenomenon that could have a certain relevance regarding the way popular sovereignty is exercised. Furthermore, it could affect the ways that social practices of emancipation might be regarded. In this respect, and starting out with a very specific consideration of the notion of “people” and “the political”, my intention is to analyze the different interpretations (critical and enthusiastic perspectives) about the judicialization of politics. Finally, I ask about the possibility of exploring the political-emancipatory potential of judicial disputes.; Cet article se penche sur la judiciarisation de la politique dans les sociétés démocratiques contemporaines en tant que phénomène qui pourrait avoir affecté les formes d’exercer la souveraineté populaire et, plus précisément, les façons de penser les processus politiques émancipatoires. En ce sens, et à partir d’une conception spécifique tant du “peuple” comme du “politique”, nous nous intéressons à problématiser les différentes interprétations (vision critique et vision enchantée) à propos de la judiciarisation de la politique. Finalement, notre étude s’interroge sur la possibilité d’explorer la potentialité politico-émancipatoire des disputes judiciaires.

El rostro femenino de los conflictos territoriales: las mujeres mapuce Garcia Gualda, Suyai Malen El Corredor de Los Lagos es un circuito turístico de notable valor para la provincia de Neuquén, Patagonia Argentina. En dicho corredor se suceden numerosos conflictos que denotan el valor económico –y político- que encierra este espacio territorial, habitado tradicionalmente por el Pueblo/Nación Mapuce. En esta oportunidad analizamos y reflexionamos sobre las disputas que han atravesado dos comunidades en particular: Plácido Puel y Paicil Antriao, pues ambas comunidades se ubican en áreas codiciadas por capitales nacionales, internacionales y el Estado. Nuestra atención se enfoca en la participación de las mujeres mapuce en los momentos de conflicto. Para ello se usará información obtenida durante el trabajo de campo y de material bibliográfico relevado a lo largo del proceso de indagación teórica. Finalmente, es pertinente señalar que el presente artículo sintetiza parte de la investigación desarrollada en el marco de mi tesis doctoral.; The Lakes Corridor is a tourist circuit with remarkable value for the province of Neuquen, Patagonia Argentina. In the Corridor, many conflicts take place, which shows the economic and political value enclosing the territory, traditionally inhabited by the Mapuche People/Nation. In this paper, we analyze and reflect the disputes that occur in two communities: Plácido Puel and Paicil Antriao. Both communities are located in territories coveted by national, international and the state interests. Our focus will be placed on the participation of Mapuche women in times of conflict. To do so, we will use information collected during field work and the bibliographic material researched along the process of theoretical inquiry. Finally, it is pertinent to note that this article summarizes some of the research developed as part of my PhD thesis.

La literatura en el proceso de investigación y enseñanza del Derecho; The literature on the process of searching and teaching of the Law Cardinaux, Nancy Susana Este texto pretende explorar la relación existente entre la literatura y el Derecho. Intenta mostrar además la relación de interdeterminación que se establece entre ambas disciplinas. Así mismo, se propone explorar en qué medida el uso “didáctico” de la literatura contribuye a consolidarla en el lugar de “ilustración” o “recurso didáctico” sobre el que se monta luego una teorización científica o jurídica así como a despojarla de su contexto y, por tanto, de su potencialidad crítica. Al texto le interesa pues el ingreso de la literatura a la cotidianeidad del aula como una forma de diálogo entre la teoría y la práctica.; This text explores the relationship between literature and law. Try also show interdeterminación relationship established between both disciplines. Likewise, it will explore to what extent the "educational" use of literature helps to consolidate the place of "enlightenment" or "educational resource" on a scientific or legal theorizing is then mounted so as to strip it of its context and therefore its critical potential . The text you want for the entry of literature to the everyday classroom as a form of dialogue between theory and practice.

Rethinking Niklas Luhmann’s theory of the phylogenesis and ontogenesis of language in light of systemic-functional linguistics; Promišljanje teorije filogeneze i ontogeneze jezika Niklasa Luhmanna u svjetlu sistemsko-funkcionalne lingvistike Calise, Santiago Gabriel This paper deals with the problems of phylogenesis and ontogenesis of language, departing from Niklas Luhmann’s general hypothesis of the co-evolution of psychic and social systems. Regarding phylogenesis, the focus in Luhmann’s theory was placed on the “pre-linguistic medium of communication” constructed by gestures, which would have been the element that stimulated the evolution of language. This sort of communication allows for the emergence of a certain social order. Here, the problem was the impossibility of identifying this social order by one of the primary forms of societal differentiation. An attempt was made to interpret in which societal contexts pre-language “emerges”. In order to do this, the author resorted to Michael Halliday’s systemic-functional linguistics. Concerning ontogenesis, the attention was directed to the concepts of action and experience. The point of departure was Ilja Srubar’s criticism of Luhmann’s theory of language, according to which the acquisition of language can be thought of as a process of translating action schemes into linguistic ones. This implies a nativist vision of language discarded by Luhmann and also by Halliday. The latter indicated that it is impossible to talk about translating non-linguistic and pre-linguistic cognition schemes into linguistic form because there is no model of experience previous to the linguistic categories. In addition, an attempt was made to show that systemic-functional linguistics can be useful to fill the gap regarding the ontogenesis of language left by Luhmann’s systems theory.; U radu se obrađuju problemi filogeneze i ontogeneze jezika odmicanjem od opće hipoteze Niklasa Luhmanna o suevoluciji psihičkih i društvenih sustava. U pogledu filogeneze jezika, naglasak je u Luhmannovoj teoriji smješten na »predjezični medij komunikacije« sačinjen od gesta, koji je mogao biti temelj poticanja evolucije jezika. Ta vrsta komunikacije omogućuje pojavu određenoga društvenog poretka. Problem je bio u nemogućnosti identificiranja toga društvenog poretka jednim od primarnih oblika socijetalne diferencijacije. Autor ovog rada nastojao je protumačiti u kojim se socijetalnim kontekstima »pojavljuje« predjezik. U tu se svrhu oslonio na sistemsko-funkcionalnu lingvistiku Michaela Hallidaya. U pogledu ontogeneze jezika, pozornost je usmjerena na koncepte djelovanja i iskustva. Kao polazna točka za to poslužila je kritika Ilje Srubara upućena Luhmannovoj teoriji jezika, prema kojoj se na stjecanje jezika može gledati kao na proces prevođenja shema djelovanja u jezične sheme. To uključuje nativističko viđenje jezika koje su odbacili i Luhmann i Halliday, od kojih je potonji sugerirao kako je nemoguće govoriti o prevođenju nejezičnih i predjezičnih spoznajnih shema u jezični oblik, jer ne postoji model iskustva koji prethodi jezičnim kategorijama. Autor je i ovdje nastojao pokazati da sistemsko-funkcionalna lingvistika može biti korisna u popunjavanju praznina koje je u tumačenju ontogeneze jezike za sobom ostavila Luhmannova sistemska teorija.

Veladas literario-musicales y manifestaciones públicas en la construcción del primero de mayo en Tucumán (Argentina), 1897-1925; Literary-musical evenings and public manifestations in the construction of may in Tucumán (Argentina), 1897-1925 Teitelbaum, Vanesa Ester En este artículo me propongo analizar las veladas y manifestaciones del 1° de Mayo en Tucumán, provincia del noroeste argentino, temática central en los estudios del mundo del trabajo pero que hasta ahora no ha sido explorada para el periodo y el espacio elegido. El corte temporal inicia, aproximadamente a finales de la década de 1890 y comienzos del novecientos --cuando se recordó por primera vez el 1° de Mayo en la provincia-- y concluye hacia mediados de los años 1920, con la intervención del Estado en dicha conmemoración. Desde una perspectiva de historia social, se analizarán documentos escritos y visuales contenidos en la prensa periódica provincial y los diarios obreros, junto con testimonios de militantes y dirigentes del periodo para indagar la construcción de este ritual obrero, así como los significados en pugna que se desplegaron torno a esta efeméride, entendida como la principal conmemoración obrera y percibida como una arena de disputa entre las distintas fuerzas del movimiento obrero, los partidos políticos y finalmente el Estado.; In his paper I will analyze the evenings and demonstrations of May 1 in Tucumán, a province in northwestern Argentina, central theme in studies of the world of work but so far has not been explored for the period and the space chosen. The temporary cut starts, about the end of the 1890s and beginning of the twentieth century - when it was recalled for the first time on 1 May in the province - and concludes in the mid-1920s, with the intervention of the State in this commemoration. From the perspective of social history, written documents and visual content on periodic provincial daily press and the workers, along with testimonials from members and leaders of the period to investigate the emergence, formation and some of the meanings that were deployed around will analyze this event, defined as the main working and commemoration perceived as an arena of contention between the various forces of the labor movement, political parties and ultimately the state.

Articulaciones y disputas en la trama entre trabajo docente e igualdad educativa en Argentina; Coordination and confrontation in the links between teaching work and educational equality in Argentina Vassiliades, Alejandro Este artículo analiza cómo la docencia en Argentina ha sido el lugar de llegada de una multiplicidad de significaciones que pugnaron por fijarla a diversos sentidos. Como significante abierto y no definido a priori, se constituyó en un campo de disputas y conflictos. Este trabajo presenta una discusión respecto del modo en que trabajo docente e igualdad educativa se articularon históricamente en dicho país y configuraron una trama compleja e inestable; se analizan sus inscripciones en cuatro momentos: el fundacional del magisterio, el de la última dictadura, el de las reformas de la década de 1990, y el de las políticas educativas desarrolladas en los últimos diez años. Estos periodos resultan momentos de fuerte condensación de debates en torno de esta articulación. El análisis se nutre de aportes metodológicos provistos por el análisis político del discurso y de investigaciones del campo del trabajo docente y la política e historia de la educación.; This paper analyzes how teaching in Argentina has been a point of entry for many different meanings that sought to lay claim to it. As an a priori open, undefined signifier, it was constituted in a field of disputes and conflicts. This paper presents a discussion on the way in which teaching work and educational equality were historically connected in this country and shaped a complex and unstable weave of meaning This is analyzed in four key moments: the foundation of the teaching body, the last dictatorship, the reforms of the 1990s, and the education policies developed over the past decade. These are moments in which the debate about this linkage comes to a head. The analysis is enriched by methodological contributions provided by the political analysis of discourse, and by research into the field of teaching work and the politics and history of education.

Exact partition function in U(2) × U(2) ABJM theory deformed by mass and Fayet-Iliopoulos terms Russo, Jorge Guillermo; Silva, Guillermo Ariel Abstract: We exactly compute the partition function for U(2)k × U(2)− k ABJM theory on S3 deformed by mass m and Fayet-Iliopoulos parameter ζ. For k = 1, 2, the partition function has an infinite number of Lee-Yang zeros. For general k, in the decompactification limit the theory exhibits a quantum (first-order) phase transition at m = 2ζ.

Deep inelastic scattering cross sections from the gauge/string duality Koile, Leandro Ezequiel; Kovensky, Nicolas; Schvellinger, Martín Alejandro Differential cross sections of deep inelastic scattering of charged leptons from hadrons are investigated by using the gauge/string duality. We consider vector mesons derived from different holographic dual models obtaining a general expression. We focus on the strongly coupled regime of dual gauge theories for different values of the Bjorken parameter. We find new predictions which are particularly interesting for differential scattering cross sections of polarized leptons scattered off polarized vector mesons. We also carry out a detailed comparison of the moments of the structure functions with lattice QCD results.

Condicionantes internos y externos que favorecen al predominio del tradicional patrón de equidistancia argentino ante la disputa palestino-israelí (1983-2015); internal and external factors that contribute to the prevalence of the traditional argentinean pattern of equidistance towards the israeli-palestinian conflict between 1983 and 2015 Fabani, Ornela Desde hace décadas el conflicto palestino-israelí se ha convertido en un tema clave en la agenda de política internacional global. En lo que atañe a Argentina, históricamente nuestro país ha adoptado una postura equidistante frente a la disputa, inaugurada ya en 1947 al momento de votarse sobre la partición de Palestina en Naciones Unidas. Ahora bien, considerando que la política exterior argentina, más allá de ciertas tendencias profundas que se relacionan con la continuidad, ha mostrado características variables que generan inestabilidad e, incluso, impredecibilidad en cuanto a las posiciones de nuestro país como actor en el sistema internacional; llama la atención la prolongación en el tiempo de este patrón de equidistancia. En tal sentido buscamos dilucidar: ¿Cuáles son y cómo inciden los condicionantes internos y externos sobre el predominio del tradicional patrón de equidistancia argentino frente al conflicto palestino-israelí entre 1983 y 2015? En búsqueda de la respuesta identificamos los factores histórico-sociales, políticos y comerciales, internos y externos, que inciden en la formulación de la política exterior frente al caso, para luego relacionar la incidencia de dichos condicionantes con las instancias de ajuste y continuidad de la política exterior argentina.; For decades the Israeli-Palestinian conflict has become a key issue in the global international policy agenda. With regard to Argentina, historically our country has adopted an equidistant position towards the dispute, inaugurated in 1947 at the time of voting on the partition of Palestine at the United Nations. Considering that Argentina’s foreign policy, beyond some deep trends related to continuity, has showed variable features that cause instability and, even, unpredictability as regards the positions of our country as an actor in the international system; it calls our attention the extension in time of this pattern of equidistance beyond the changes in political regime. As such we ask: Which are the internal and external factors and how they impact on the prevalence of the traditional Argentinean pattern of equidistance towards the Israeli-Palestinian conflict between 1983 and 2015? In search of the answer we aim to identify the socio-historical, political and commercial, internal and external factors affecting the formulation of foreign policy towards the case, in order to be able to relate the incidence of these conditions with the instances of adjustment and continuity of Argentina’s foreign policy.

Juntos, pero no tanto: un recorrido por la agenda de negociaciones comerciales externas del MERCOSUR (1991-2015); Together, but not so much: a tour through the agenda of external trade negotiations of MERCOSUR (1991-2015) Zelicovich, Julieta El objetivo de este trabajo es analizar el desarrollo de la dimensión externa del MERCOSUR en el período 1991-2015, constituida a partir de cuatro sub agendas, a saber: a) Las negociaciones del patrimonio histórico; b) Las negociaciones con socios de extra-zona Norte/Sur; c) Las negociaciones con socios de extra-zona Sur/Sur; d) Las negociaciones en los organismos multilaterales. Se sostiene que el MERCOSUR ha tenido un desempeño limitado en su accionar externo. Los problemas de coordinación intrabloque han ido en desmedro de la capacidad negociadora, y, en cuanto a resultados, una vez superadas las negociaciones del seno de la ALADI, en los nuevos acuerdos que han podido celebrarse, el volumen de comercio abarcado es bajo.; The aim of this paper is to analyze the development of the external dimension of MERCOSUR during the period 1991- 2015. This dimension is integrated by four subagendas, namely: a) the negotiations of the historical heritage; b) the negotiations with third-partners in the axis North/South; c) the negotiations with third-partners in the axis South/South; d) the negotiations in multilateral organizations. It is argued that MERCOSUR has had a limited performance in its external action. Intrabloc coordination problems have eroded the negotiating capacity; and as regards of the results achieved, once passed the negotiations of the ALADI, the coverage in terms of trade volume of the new agreements that have been concluded is low.

Omics approaches for the engineering of pathogen resistant plants Gomez Casati, Diego Fabian; Busi, María Victoria; Pagani, María Ayelén; Bhadauria, Vijai The attack of different pathogens, such as bacteria, fungi and viruses has a negative impact on crop production. In counter such attacks, plants have developed different strategies involving the modification of gene expression, activation of several metabolic pathways and posttranslational modification of proteins, which culminate into the accumulation of primary and secondary metabolites implicated in plant defense responses. The recent advancement in omics techniques allows the increase coverage of plants transcriptomes, proteomes and metabolomes during pathogen attack, and the modulation of the response after the infection. Omics techniques also allow us to learn more about the biological cycle of the pathogens in addition to the identification of novel virulence factors in pathogens and their host targets. Both approaches become important to decipher the mechanism underlying pathogen attacks and to develop strategies for improving disease-resistant plants In this review, we summarize some of the contribution of genomics, transcriptomics, proteomics, metabolomics and metallomics in devising the strategies to obtain plants with increased resistance to pathogens. These approaches constitute important research tools in the development of new technologies for the protection against diseases and increase plant production.

Aproximaciones de la museología al entorno web: Exhibición online de la colección del MNBA; Museological approach to web space: Online Exhibition of the MNBA´s Collection Panozzo Zenere, Alejandra Gabriela La presencia en Internet del Museo Nacional de Bellas Artes de Argentina no escapa a las innovaciones tecnológicas-comunicativas que transformaron en las últimas décadas la museología en general. En consecuencia, esta institución adoptó distintas especificidades dentro del entorno virtual para poder exponer su patrimonio artístico. En este trabajo, se intentará repasar de forma preliminar y exploratoria algunas construcciones que se evidencian dentro del diseño del sitio web y las prestaciones que permite el proyecto de Google, para luego, introducirnos en la función de exhibición online de sus obras de arte como imágenes pixeles. El rasgo que presenta este tipo de patrimonio nos acerca a una manera específica de exhibición de sus colecciones en el entorno virtual. El Consejo Internacional de Museos (ICOM) considera que los museos deben velar para que sus exposiciones físicas y virtuales presenten información fehaciente, conforme a las misiones, políticas y finalidades declaradas por cada institución. Por tanto, el recorrido de este trabajo plantea como objetivo analizar las implicancias y de qué manera el MNBA expone su patrimonio de manera virtual a partir de su portal www.mnba.gob.ar y desde la experiencia Google art project.; The online presence of the Argentine National Fine Arts Museum (MNBA) cannot be conceived without considering the technological and communicative innovations that have transformed museum studies over the last decades. This institution has, therefore, adopted a number of specific virtual tools to display its art heritage. This work aims to revise in a preliminary and exploratory way some constructions within website design and the tools offered by Google Art Project, in order to then focus on the online display of works of art as series of pixels. The most distinctive features of this type of heritage lead us to a specific way of exhibiting art collections in the virtual space. The International Council of Museums (ICOM) considers that museums should look out for their physical and virtual exhibits presenting trustworthy information, in accordance with the aims, policies, and purposes set by the above mentioned institution. Thus, the aim of this outline will be to consider the implications and the strategies used by the MNBA to exhibit its art heritage online, by means of both its own website www.mnba.gob.ar and the Google Art Project platform.

Partidos, sindicatos y movimientos sociales en Argentina y Brasil (2003-2011): la compleja relación con gobiernos afines; Parties, unions and social movements in Argentina and Brazil (2003-2011): the complex relation with related governments Benetti, María Gabriela; Iglesias, Esteban El presente artículo analiza los vínculos entre partidos políticos, sindicatos y movimientos sociales en perspectiva comparada en Brasil y Argentina en el lapso 2003/2011. Para el caso de Brasil, el período abarca los dos mandatos presidenciales de Inácio Lula Da Silva; en Argentina la presidencia de Néstor Kirchner (2003/2007) y el primer período de gestión de Cristina Fernández de Kirchner (2007/2011). En ambos casos, se trata de experiencias de gobierno que se inscriben en un escenario regional de quiebre del consenso neoliberal y que tienen por protagonistas a partidos políticos –el PT brasileño y el peronismo en Argentina– con un fuerte vínculo con los sindicatos y movimientos sociales que se referencian en ellos y que, por tanto, los identifican como “sus” gobiernos. Analizamos el siempre complejo juego de las lealtades e identidades políticas que operan como límite tanto para el diseño de políticas como para las respuestas que se generan desde abajo.; The following article analyzes the links between the political parties, the trade unions and the social movements taking into account the comparative perspective of Brazil and Argentina in the period 2003/2011. In the case of Brazil, the period encompassing the two presidential mandates of Inacio Lula Da Silva, in Argentina Néstor Kirchner’s presidency (2003/2007) and the first period of Cristina Fernandez de Kirchner (2007/2011). In both cases, there are government experiences that are part of a regional scenario where the neoliberal consensus is broken and where the main characters of political parties - the Brazilian PT and Peronism in Argentina have a strong link with the trade unions and social movements which feel represented by them, and hence identify them as “their” governments. We analyze thoroughly the complex set of loyalties and political identities that act as a boundary for the policy design and the responses generated from the inner levels.

Modulación de la respuesta a insulina en el ovario bovino y su relación con la enfermedad quística ovárica; Modulation of insulin response in ovarian cattle and its relationship with cystic ovarian disease Panzani, Carolina Guadalupe; Hein, Gustavo Juan; Salvetti, Natalia Raquel; Ortega, Hugo Hector; Rey, Florencia La enfermedad quística ovárica bovina es una importante enfermedad que afecta la fertilidad del ganado bovino lechero. Diversos procesos ováricos tales como la proliferación celular y la esteroidogénesis se encuentran regulados por numerosas hormonas entre las que se encuentra la insulina. La respuesta a esta hormona se desencadena luego de la unión a su receptor específico. El objetivo de la presente revisión es analizar la función de intermediarios claves en la vía de señalización intracelular, que actúan en los primeros estadios involucrados en la respuesta a insulina. Se analizan el receptor de insulina (IR), el sustrato -1 del IR (IRS1) y la enzima fosfatidilinositol 3-quinasa (PI3K) denotando modificaciones ocurridas en folículos quísticos que podrían influenciar negativamente en la funcionalidad de ovarios y contribuir a la persistencia folicular.; Cystic ovarian disease (COD) is an important disease affecting fertility in dairy cattle. Several ovarian processes such as cell proliferation and follicular cell steroidogenesis are regulated by numerous hormones including insulin. The hormone response is triggered after the binding to its receptor. The aim of this review is to analyze the role of key intermediates in the intracellular signaling pathway that act in the early stages of the insulin response. Therefore, insulin receptor (IR), IR substrate-1 (IRS1) and phosphatidylinositol-3-kinase (PI3K) are analyzed showing changes that occur in cystic follicles and which could negatively influence the functionality of ovaries and contribute to follicle persistence.
