Dependence on nuclear factor of activated T-cells (NFAT) levels discriminates conventional T cells from Foxp3 + regulatory T cells
2012
Several lines of evidence suggest nuclear factor of activated T-cells (NFAT) to control regulatory T cells: thymus-derived naturally occurring regulatory T cells (nTreg) depend on calcium signals, the Foxp3 gene harbors several NFAT binding sites, and the Foxp3 (Fork head box P3) protein interacts with NFAT. Therefore, we investigated the impact of NFAT on Foxp3 expression. Indeed, the generation of peripherally induced Treg (iTreg) by TGF-β was highly dependent on NFAT expression because the ability of CD4 + T cells to differentiate into iTreg diminished markedly with the number of NFAT family members missing. It can be concluded that the expression of Foxp3 in TGF-β–induced iTreg depends…
Ciencia del Comercio, Economía Política y Economía Civil en la Ilustración Española (1714-1808)
2019
The chronology of economic ideas in Spanish Enlightenment is well known. However, the most accepted periodization does not fit with the evolution of moral philosophy and political economy in the 18th century, nor does it reflect the alternation in economic ideologies. After considering a joint articulation of national and generational approaches to the European economic thought, it seems important to differentiate the contents of political economy and civil economy to study the Spanish case. Below is a new periodization in five stages of enlightened economic thought in Spain: the time of colbertism and projectism (1714-1740), this of the learning of the science of commerce in Ensenada’s per…
La evolución de las pautas de consumo de las familias valencianas. Una aproximación a los cambios de comportamiento en el siglo XVIII
2019
En las áreas más dinámicas de la Europa Occidental la llamada revolución del consumo hizo su aparición a finales del xvii. También en la España Mediterránea se produjeron cambios significativos en las pautas adquisitivas de las familias, derivados del excepcional desarrollo económico experimentado a lo largo del siglo xviii. Cambios que dudamos en calificar de revolucionarios –ya que responden a un proceso progresivo en el que intervienen múltiples variables–, y que en nuestra opinión consideramos que el término que mejor caracteriza este período es el de evolución del consumo. La base documental utilizada en este estudio comparativo la constituye un conjunto de escrituras de dote repartida…
Segundo de Chomón, un guía turístico de cine.
2013
Desde sus orígenes el cine ha sido un poderoso creador de imaginarios sobre las culturas y los países del mundo. Por lo mismo, ha contribuido a configurar la imagen de España como destino turístico. Aunque los primeros documentales sobre España fueron filmados por camarógrafos extranjeros, muy pronto los operadores españoles empezaron a realizar sus propias películas, contribuyendo a conformar el imaginario fílmico nacional. Entre ellas destacan los documentales turísticos realizados para la firma Pathé por Segundo de Chomón, cuya habilidad narrativa y compositiva sientan las bases del género. Con ellos, sin obviar las expectativas espectatoriales, el cineasta consigue aportar un plus de re…
From Theatre to Theatricality—How to Construct Reality
1995
At the end of the nineteenth century, the dominance of language, so typical of Western culture since the Renaissance, was increasingly challenged. As early as 1876, Nietzsche wrote on Richard Wagner in Thoughts Out of Season:He was the first to recognize an evil which is as widespread as civilization itself among men; language is everywhere diseased, and the burden of this terrible disease weighs heavily upon the whole of man's development. Inasmuch as language has retreated ever more and more from its true province— the expression of strong feelings, which it was once able to convey in all their simplicity—and has always had to strain after the practically impossible achievement of communi…
Visual literacy practices in higher education: what, why and how?
2019
A bilingual five-year-old girl is trying to explain to her mother what she was doing at gymnastics class. Despite her best efforts to overcome the excitement, speaking a mixture of two languages an...
‘Des singes, c’était le narcisse’: class, imitation and performing monkeys in late-eighteenth century Paris
2018
This paper focuses on the use of performing monkeys in boulevard and foire theatres in late eighteenth-century Paris. I will concentrate on the issues raised by ‘Turco,’ Jean-Baptiste Nicolet’s leg...
Colonization pattern of primary tomato roots by Pseudomonas fluorescens A6RI characterized by dilution plating, flow cytometry, fluorescence, confoca…
2004
Early colonization of primary tomato roots, grown in vitro, by Pseudomonas fluorescens A6RI, introduced by seed bacterization, was monitored for 7 days in three different root zones (zone A, apex+elongation+young hairy zone; zone B, hairy zone; zone C, old hairy zone+collar). Bacterial quantification was assessed by enumeration of (i) colony forming units (cfu) after dilution plating and of (ii) total bacterial cells by flow cytometry. Bacterial distribution and organization in the root zones were analyzed by fluorescence, confocal and scanning electron microscopy. For all sampling dates and zones, the densities of total bacterial cells were significantly higher than those of the cfu. The k…
Laser speckle imaging for early detection of microbial colony forming units
2021
In this study, an optical contactless laser speckle imaging technique for the early identification of bacterial colony-forming units was tested. The aim of this work is to compare the laser speckle imaging method for the early assessment of microbial activity with standard visual inspection under white light illumination. In presented research, the growth of Vibrio natriegens bacterial colonies on the solid medium was observed and analyzed. Both – visual examination under white light illumination and laser speckle correlation analysis were performed. Based on various experiments and comparisons with the theoretical Gompertz model, colony radius growth curves were obtained. It was shown that…
Laser speckle time-series correlation analysis for bacteria activity detection
2020
The study aims at development and laboratory approbation of non-contact optical technique for early evaluation of microbial activity. Microorganisms’ activity is estimated by laser speckle contrast imaging technique in combination with image processing of obtained time varying speckle patterns. Laser speckle patterns were captured by CMOS sensor during illumination of growing bacteria colonies by low power (<30 mW, 635 nm) stabilized coherent light source. To validate proposed technique and image processing algorithm the vibrio natriegens bacteria are used. After analysis of several different experiments the following results were obtained: In the central part of the colony activity can be …
