Response to long-term NaHCO3-derived alkalinity in model Lotus japonicus Ecotypes Gifu B-129 and Miyakojima MG-20: transcriptomic profiling and physi…
2014
The current knowledge regarding transcriptomic changes induced by alkalinity on plants is scarce and limited to studieswhere plants were subjected to the alkaline salt for periods not longer than 48 h, so there is no information availableregarding the regulation of genes involved in the generation of a new homeostatic cellular condition after long-termalkaline stress.Lotus japonicusis a model legume broadly used to study many important physiological processes includingbiotic interactions and biotic and abiotic stresses. In the present study, we characterized phenotipically the response toalkaline stress of the most widely usedL. japonicusecotypes, Gifu B-129 and MG-20, and analyzed global t…
Suprachoroidal Bleeding After XEN Gel Implantation
2017
Purpose To report for the first time a clinical case of suprachoroidal bleeding after XEN45 gel implantation. Observations A 84-year old female patient with pseudoexfoliation glaucoma with intraocular pressure (IOP) (20 mm Hg) above target despite maximal IOP-lowering therapy was scheduled for XEN45 gel implantation. The XEN45 gel implantation went without complications and was properly placed in the anterior chamber and beneath the conjunctiva. On the first postoperative day, the patient presented with an IOP of 4 mm Hg, a functioning bleb and a deep anterior chamber. On the second day she developed suprachoroidal bleeding. A wait and see strategy was followed and the patient monitored ste…
Representation of Peronist unionism in Argentinian sociologist Roberto Carri’s works: From the “vandorismo” to the guerilla “Montoneros” (1967-1974)
2019
En este trabajo abordamos un aspecto de la trayectoria intelectual del sociólogo argentino Roberto Carri, referido a sus estudios sobre el sindicalismo argentino, específicamente el sindicalismo peronista después de 1955. Para hacerlo tomamos en cuenta tres textos claves que le dedicó al tema, en tres momentos particulares de su trayectoria intelectual y militante: el libro Sindicatos y Poder en la Argentina (1967), el artículo ?Sindicalismo de participación, sindicalismo de liberación? (1971), y el texto ?Vandorismo. La política del imperialismo para los trabajadores peronistas? (1974). En estos textos analizaremos cinco elementos: la lectura de la relación entre el peronismo y los sindica…
Elogio del populismo (en ciertas circunstancias). Notas sobre el kirchnerismo en Argentina
2014
Los trabajos de Ernesto Laclau (2005, 2009) han inspirado una teoría política del populismo que constituye una superación de los enfoques precedentes y que conviene revisar como andamiaje analítico y heurístico. Esta teoría nos ayuda a reconstruir tres dimensiones polémicas que han sido objeto de los estudios sobre la temática. Primero, el populismo asociado a un tipo de discurso. Segundo, como una lógica política que apunta a la producción de una identidad popular (el pueblo) a partir de la interpelación y de la articulación. Tercero, como un proceso político que refiere a la inclusión radical, la transformación del orden social y su relación con la democracia. Como veremos, esta diferenci…
Science and gender: researchers in training at the end of Francoism
2017
espanolDurante el siglo XX, al compas del incremento en el acceso a los estudios superiores, las mujeres comenzaron a romper barreras en el campo de la investigacion. El objetivo principal de este estudio es comprobar la forma en que incidio sobre el acceso de la mujer a la ciencia la primera convocatoria del Plan de Formacion de Personal Investigador (1968), inscrito dentro del II Plan de Desarrollo Economico y Social (1968/71), y las sucesivas convocatorias de becas pre y post doctorales, con destino a Espana y al extranjero, que se resolvieron hasta 1975. Mediante un analisis cuantitativo de los datos, en perspectiva de genero, trataremos de determinar las diferentes vias a traves de las…
Detailed study of SNR G306.3–0.9 using XMM-Newton and Chandra observations
2016
Aims. We aim to study the spatial distribution of the physical and chemical properties of the X-ray emitting plasma of the supernova remnant (SNR) G306.3-0.9 in detail to obtain constraints on its ionization stage, the progenitor supernova explosion, and the age of the remnant. Methods. We used combined data from XMM-Newton and Chandra observatories to study the X-ray morphology of G306.3-0.9 in detail. A spatially resolved spectral analysis was used to obtain physical and geometrical parameters of different regions of the remnant. Spitzer infrared observations, available in the archive, were also used to constrain the progenitor supernova and study the environment in which the remnant evol…
Measurement of the radiation energy in the radio signal of extensive air showers as a universal estimator of cosmic-ray energy
2016
We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Auger Observatory, we obtain a radiation energy of 15.8±0.7(stat)±6.7(syst) MeV for cosmic rays with an energy of 1 EeV arriving perpendicularly to a geomagnetic field of 0.24 G, scaling quadratically with the cosmic-ray energy. A comparison with predictions from state-of-the-art first-principles calculations shows agreement with our measurement. The radiation energy provides direct access to the calorimetric energy in the electromagnetic cascade of extensive air showers. Comparison with our result thus allows the d…
Performance of jet substructure techniques for large-$R$ jets in proton-proton collisions at $\sqrt{s}$ = 7 TeV using the ATLAS detector
2013
This paper presents the application of a variety of techniques to study jet substructure. The performance of various modified jet algorithms, or jet grooming techniques, for several jet types and event topologies is investigated for jets with transverse momentum larger than 300 GeV. Properties of jets subjected to the mass-drop filtering, trimming, and pruning algorithms are found to have a reduced sensitivity to multiple proton-proton interactions, are more stable at high luminosity and improve the physics potential of searches for heavy boosted objects. Studies of the expected discrimination power of jet mass and jet substructure observables in searches for new physics are also presented.…
Cerebral Dynamics during the Observation of Point-Light Displays Depicting Postural Adjustments
2017
Objective: As highly social creatures, human beings rely part of their skills of identifying, interpreting, and predicting the actions of others on the ability of perceiving biological motion. In the present study, we aim to investigate the electroencephalographic (EEG) cerebral dynamics involved in the coding of postural control and examine whether upright stance would be codified through the activation of the temporal-parietal cortical network classically enrolled in the coding of biological motion. Design: We registered the EEG activity of 12 volunteers while they passively watched point light displays (PLD) depicting quiet stable (QB) and an unstable (UB) postural situations and their r…
Lemon Oils Attenuate the Pathogenicity of Pseudomonas aeruginosa by Quorum Sensing Inhibition
2021
The chemical composition of three Citrus limon oils: lemon essential oil (LEO), lemon terpenes (LT) and lemon essence (LE), and their influence in the virulence factors production and motility (swarming and swimming) of two Pseudomonas aeruginosa strains (ATCC 27853 and a multidrug-resistant HT5) were investigated. The main compound, limonene, was also tested in biological assays. Eighty-four compounds, accounting for a relative peak area of 99.23%, 98.58% and 99.64%, were identified by GC/MS. Limonene (59–60%), γ-terpinene (10–11%) and β-pinene (7–15%) were the main compounds. All lemon oils inhibited specific biofilm production and bacterial metabolic activities into biofilm in a dose-dep…
