1901102018Haciendo historia regional en la ArgentinaLa historia regional puede volverse un campo fértil y operativo, sobre todo si se evita su delimitación anticipada y se atiende a la construcción de relaciones sociales que, en última instancia, permitirán su definición como ámbito regional, avanzando así en niveles explicativos del comportamiento de la sociedad en un espacio más reducido, aunque no excesivamente ?micro? ni exclusivamente local. Tales relaciones responden siempre a realidades macro sociales más amplias, las enriquecen y aún pueden llegar a corregir las interpretaciones generalizantes de las historias nacionales. El historiador debe entonces prestar especial atención a los cambios temporales de la espacialidad y a su variación social, porque sus ?regiones? cambiarán de acuerdo a la época y a las finalidades de su estudio. Se desarrollan en este trabajo los aportes conceptuales más válidos en ese sentido, así como su aplicación empírica en diferentes trabajos de investigación histórica realizados en la Argentina.HISTORIA|REGIONAL|ARGENTINA|ESTADO DE LA CUESTION
381014201821-hydroxy-6,19-epoxyprogesterone: a Promising Therapeutic Agent and a Molecular Tool for Deciphering Glucocorticoid ActionGlucocorticoids are steroid hormones that exert most of their effects through their binding to the glucocorticoid receptor (GR), a ligand regulated transcription factor. Although glucocorticoids are widely used in the clinic, their usage in chronic therapies provokes severe adverse reactions. In the quest for safer glucocorticoids a dissociated model was established that proposes a disconnection between GR activated pathways responsible of desired pharmacological effects and pathways involved in adverse GR reactions. Under this model, a myriad of steroidal and non-steroidal compounds has been characterized, with most of them still producing side effects. X-ray crystallographic studies followed by molecular dynamics analysis led research to insights on the receptor Ligand Binding Domain (LBD), which undergoes specific ligand dependent conformational changes that influence receptor activities. In this sense, the flexibility of the ligand structure would contribute to the final GR outcome. Here, we review different data of 21-hydroxy-6,19-epoxyprogesterone (21OH-6,19OP), a rigid steroid with potential pharmaceutical interest due to its anti-inflammatory and immunosuppressive activities, lacking several GR adverse reactions. The rigid structure endows this compound with an enhanced selectivity towards GR. Molecular characterization of the GR/21OH-6,19OP complex revealed specific intermediate conformations adopted by the receptor that would explain the influence on GR dimerization and the recruitment of a specific set of GR transcription modulators. We summarize recent data that will contribute to understand the complexity of glucocorticoid response.GLUCOCORTICOID RECEPTOR|ANTIGLUCOCORTICOID
4637142018Detection of Nitric Oxide and Determination of Nitrite Concentrations in Arabidopsis thaliana and Azospirilum brasilenseThere is now general agreement that nitric oxide (NO) is an important and almostubiquitous signal in plants. Nevertheless, there are still many controversial observations and different opinions on the importance and functions of NO in plants. Partly, this may be due to the difficulties in detecting and even more in quantifying NO. Here, we summarize protocols for detecting NO and quantifying nitrite concentration in Arabidopisis seedlings and for the NO real time measurement in biofilms formed by the plant growth promoting rhizobacteria Azospirillum brasilense (A. brasilense). NO in oxygen-containing aqueous solution has a short half-life that is often attributed to a rapid oxidation to nitrite. Here we detail the use of the fluorescent probe DAF-FM DA and the electrochemical method for directly detecting and quantifying NO,respectively, and the Griess reagent to indirectly detect NO through its oxidized nitrite form.These protocols could be useful in a variety of cell types and different tissues of plants, and for microorganisms.NITRIC OXIDE|NITRITE|ARABIDOPSIS|AZOSPIRILLUM
4824142018Using Ground-Penetrating RADAR to investigate the Internal Structure of Puente del Inca, Mendoza, ArgentinaABSTRACTWe performed ground-penetrating radar measurements to study the internal structure of Puente delInca (Inca Bridge). This natural structure is located in Mendoza, Argentina, and its formation isassociated with deposition of travertine caused by geobiological processes created by hot mineralsprings. The 200-MHz ground-penetrating radar measurements performed on the surface of thebridge allowed us to relate the behaviour of the electromagnetic signal with the presence or absenceof hot spring activity. We also made ground-penetrating radar measurements at 20 MHz to estimatethe propagation velocity and study the bridge?s internal structure. In order to validate the groundpenetratingradar results, we used a soil dielectric sensor to obtain the attenuation and the velocityof the medium. The results showed similar propagation velocities (0.0222 m/ns on average) betweenfield observation (ground-penetrating radar) and independent sensor data, as well as significantattenuation due to the hot spring water, which is the primary element controlling the response of theelectromagnetic signals. As checked through dielectric sensor measurements, the unusually lowelectromagnetic wave velocity is due to polarisation mechanisms related to thermal water, whichcause a very high permittivity value (178.1). However, the medium is not sufficiently dispersive(conductivity=27.7 mS/m; attenuation=3.5 dB/m) to condition the results of ground-penetratingradar measurements if low-frequency antennas (20 MHz) are used.GPR|radar detection|systems geobiology|natural bridge
5090142018Carcass utilization and bone modifications on guanaco killed by puma in northern Patagonia, ArgentinaInspired by the early fieldwork of G. Haynes with large sized predators in wilderness areas, the following paper presents data on bone damage patterns in a sample of guanacos killed by one of the largest predators in South America, the puma (Puma concolor, Felidae, Carnivora). We describe the bone modification pattern on the carcasses, including skeletal part representation, bone fractures, and tooth marks. Also, tooth mark modifications on bones collected from a puma enclosure at a local zoo were analyzed. Our results indicate a light modification of guanaco carcass by puma; bone damages located mainly in the upper portions of rear and forelimbs, rib cage, and scapular and pelvic girdles; and the presence of a low percentage of fractured bones. Scores, pits, and punctures are the best represented tooth marks. On average, punctures are 3.5-5 mm in diameter, although larger tooth impressions are observed. The light consumption of guanaco by the puma would provide a potential source for scavenging by other carnivores and humans.Actualistic taphonomy|Puma concolor|Lama guanicoe|Bone modifications|Carcass utilization|Southern South America
5105142018Effects of phosphites on ripening in kiwifruit 'Hayward'The phosphites (Phi) are inducers of plant defense responses, although also other effects were reported. In kiwifruit (Actinidia deliciosa Hayward), we demonstrated that Phi-treated fruit was more tolerant to gray mold development caused by Botrytis cinerea. The mechanisms are not yet well elucidated. The objective of this work was to evaluate the effect of Phi (30% P2O5, 20% K2O), 0.3% (v/v) on Hayward fruit maturity and quality indexes, by application at different physiological stages of the fruit development: T1) one application at bloom; T2) six weekly Phi applications at the exponential phase of fruit growth; T3) combination of treatments, 1 and 2; T4) control (without Phi). Kiwifruits of all treatments were harvested after physiological maturity (at least 6.2% total soluble solids content, SSC) and were analyzed at harvest in terms of firmness (N), SSC (%), titratable acidity (%) and color (CIELab). Also fruits were evaluated after 4 months of cold storage and shelf-life (7 days at 20°C). Ethylene and carbon dioxide rate production were determined at 20°C in the fruits of all treatments. The experiment was conducted during two consecutive years. The results show that the Phi had an effect on firmness, variation between years, while had no effects on other maturity indexes. Firmness of Phi-treated fruits was higher than control ones at shelf-life, essentially when Phi was applied at the exponential phase of fruit growth. This change in the softening rate was associated with the ethylene production rate that was too affected by some Phi treatments. Phi treatments (T2 and T3) significantly affected the ethylene and respiration rates, reducing significantly the values at the climacteric peak. This result suggests that Phi affects perception or biosynthesis of ethylene, and some of this response may be related to the induction of salicylic acid.Actinidia deliciosa|Ethylene|Firmness|Elicitor|Maturation
5187152018'DIVERSIDAD GENÉTICA EN RESTOS HUMANOS ARQUEOLÓGICOS DEL SITIO EL DIQUECITO (COSTA SUR, LAGUNA MAR CHIQUITA, PROVINCIA DE CÓRDOBA)'En este trabajo presentamos resultados del análisis de haplogrupos y secuencias de la Región Hipervariable I del ADN mitocondrial (RHV-I) en restos humanos del sitio El Diquecito, en la región sur de la Laguna Mar Chiquita, provincia de Córdoba, con antigüedades comprendidas entre 2562 ± 47 y 537 ± 57 14C años AP. De los 14 individuos analizados, 13 pudieron ser tipificados por APLP. Siete fueron asignados al haplogrupo C, cuatro al haplogrupo D y el restante no pudo ser amplificado por PCR. Se obtuvieron secuencias de 10 individuos, y todos ellos pudieron ser asignados con certeza a un linaje mitocondrial de origen continental americano, que coincidió con el determinado previamente por APLP. Entre las 7 secuencias correspondientes al haplogrupo C1 se reconocen 2 haplotipos diferentes, aunque sólo una no presenta el haplotipo nodal. Entre las 4 secuencias pertenecientes al haplogrupo D1 se distinguen 3 haplotipos diferentes: uno corresponde al haplotipo nodal, otro al subhaplogrupo D1j y los dos restantes al subhaplogrupo D1g. Si bien las conclusiones que pueden realizarse a partir del estudio de un solo sitio son limitadas, el estudio de la diversidad de linajes mitocondriales de los pobladores antiguos de la costa sur de la Laguna Mar Chiquita representa un nuevo aporte para comprender los procesos microevolutivos que sufrieron las poblaciones originarias del centro de Argentina.ARQUEOGENÉTICA|ADN MITOCONDRIAL|CONTINUIDAD POBLACIONAL
5281152018Nuevas investigaciones sobre la tecnología ósea en el sudoeste de la provincia de Buenos Aires. Procesos de manufactura y usoSe presentan nuevos datos del análisis tecno-morfológico y funcional de artefactos óseos provenientes de sitios ubicados en entornos acuáticos del sudoeste de la Provincia de Buenos Aires; cronológicamente se asignan al Holoceno medio y tardío. Los artefactos presentan morfologías diversas que incluyen puntas aguzadas, romas y un bisel. En algunos fue posible identificar trazas diagnósticas de la cinemática y de las superficies sobre las cuales se trabajó. En los artefactos procedentes de contextos del Holoceno medio, las acciones inferidas corresponden a movimientos transversales sobre superficies duras, incluso el trabajo sobre roca. Por su parte, en aquellos datados en el Holoceno tardío se observaron evidencias de acciones rotatorias sobre superficies blandas y transversales producidas por el trabajo sobre cuero.TECNOLOGIA OSEA|ANÁLISIS FUNCIONAL Y TECNO-MORFOLOGICO|CAZADORES RECOLECTORES|SUDOESTE BONAERENSE

6558142018CrowdMock: An Approach for Defining and Evolving Web Augmentation RequirementsWeb Applications are accessed by millions of users with different needs, goals, concerns, or preferences. Several well-known Web Applications provide personalized features, e.g., they recommend specific content to users by contemplating individual characteristics or requirements. However, since most Web Application cannot consider all users? requirements, many developers started to create their own mechanisms for adapting existing applications. One of the most popular techniques for third-party applications adaptation is Web Augmentation, which is based on the alteration of its original user interface, generally by using scripts running at the client side (e.g., the browser). In the context of Web Augmentation, two user roles have emerged: scripters who are those users able to create a new augmentation artifact, and end users without programming skills, that just consume the artifacts that may satisfy totally or partially their needs. Scripters and end users generally do not know each other, and they have rarely a contact, beyond the fact that they use the same script repositories. When end users cannot get their needs covered with existing artifacts, they claim for new ones by specifying their requirements (called Web Augmentation requirements) using textual descriptions, which are usually hard to interpret by scripters. Web Augmentation requirements are a very particular kind of Web requirements for which there partially exist a solution implemented by the Web site owner, but still users need to change or augment that implementation with very specific purposes that they desire to be available in such site. In this paper, we propose an approach for defining and evolving Web Augmentation requirements using rich visual prototypes and textual descriptions that can be automatically mapped onto running software artifacts. We present a tool implemented to support this approach, and we show an evaluation of both the approach and the tool.Requirements engineering|Web engineering|Web augmentation
