Asociacionismo, ciudadanía y bienestar social
2004
Durante las dos últimas décadas del siglo XX, se ha producido un giro histórico en el asociacionismo español, que se plasma tanto en la creación de asociaciones y en la participación asociativa, como en la institucionalización (leyes del voluntariado, de asociaciones, etc.) y en el interés académico que suscita el fenómeno. Tres interpretaciones se han dado del mismo: una utópica, que lo considera como expresión de una radicalización participativa; otra crítica, que ve en el mismo un subterfugio para diluir la privatización del Estado de bienestar, y una integrada, que habla en términos de la aparición de un tercer sector junto al mercado y el Estado. Cada una de ellas es sugerente, pero in…
Kult św. Rocha w Dobrzeniu Wielkim jako reakcja na epidemie XVII-XIX w. (na przykładzie Opolszczyzny)
2021
For nearly four centuries, the cult of St. Roch in Dobrzeń Wielki has been nurtured. In 1658, a church was built there as a token of gratitude that the prayers of the faithful had been heard and the plague had stopped. Peoples responses to the epidemics which they had experienced varied widely. They were treated as misfortunes accompanying natural disasters, which resulted in poverty and hunger. They were also a consequence ofman-made wars. Their frequent occurrence was influenced by poor hygienic conditions in which they used to live. Doctors did not also have much experience in combating infectious diseases. They were often treated as a divine punishment for sins. Therefore, efforts were …
Morphology changes induced by intercellular gap junction blocking: A reaction-diffusion mechanism.
2021
Complex anatomical form is regulated in part by endogenous physiological communication between cells; however, the dynamics by which gap junctional (GJ) states across tissues regulate morphology are still poorly understood. We employed a biophysical modeling approach combining different signaling molecules (morphogens) to qualitatively describe the anteroposterior and lateral morphology changes in model multicellular systems due to intercellular GJ blockade. The model is based on two assumptions for blocking-induced patterning: (i) the local concentrations of two small antagonistic morphogens diffusing through the GJs along the axial direction, together with that of an independent, uncouple…
Contactus adherens, a special type of plaque-bearing adhering junction containing M-cadherin, in the granule cell layer of the cerebellar glomerulus.
1995
In the glomeruli of the granule cell layer of mammalian cerebellum, neuronal extensions are interconnected by numerous small, nearly isodiametric (diameters up to 0.1 micron), junctions previously classified as puncta adherentia related to the vinculin-containing, actin microfilament-anchoring junctions of the zonula adherens of epithelial and certain other cells. Using immunofluorescence and immunoelectron microscopy, we have found, however, that these junctions are negative for E- and VE-cadherin, for desmosomal cadherins, and also for vinculin, alpha-actinin, and desmoplakin, but they do contain, in addition to the protein plakoglobin common to all forms of adhering junctions, the plaque…
Agouti-Related Proteins (AGRPs) and Agouti-Signaling Peptide (ASIP) in Fish and Chicken
2005
We performed an intensive search on sequence databases to identify orthologues of ASIP and AGRP peptides in a number of different species, revealing a number of genomic fragments coding for the C-terminal part of agouti-related motifs, different from annotated peptide sequences, including one fragment from chicken, two from zebrafish, two from Fugu (Takifugu rubripes), and three from Tetraodon (Tetraodon nigroviridis). We have thus shown for the first time that both AGRP and ASIP genes exist in many species in "lower vertebrates" and were most probably present in early stages of vertebrate evolution.
Effectiveness of interceptive treatment of class III malocclusions with skeletal anchorage: A systematic review and meta-analysis
2017
Recently, new strategies for treating class III malocclusions have appeared. Skeletal anchorage appears to reduce the dentoalveolar effects while maximising the orthopaedic effect in growing patients. The purpose of this systematic review and meta-analysis is to examine the effectiveness of bone anchorage devices for interceptive treatment of skeletal class III malocclusions. Searches were made in the Pubmed, Embase, Scopus and Cochrane databases, as well as in a grey literature database, and were complemented by hand-searching. The criteria for eligibility were: patients who had undergone orthodontic treatment with skeletal anchorage (miniplates and miniscrews). Patients with syndromes or …

La construcción de subjetividades en el Tercer Sector: aproximación a las Empresas de Inserción en el marco del Capitalismo Flexible
2016
El presente trabajo de Tesis Doctoral pretende realizar una aproximación a las Empresas de Inserción, sus prácticas, lógicas y efectos en el marco de las entidades del Tercer Sector. El objetivo que perseguimos al aproximarnos a las Empresas de Inserción es describir su situación en la sociedad actual atendiendo al papel que juegan las entidades en la construcción de subjetividades. Hacerlo posibilitará la comprensión y el análisis de las prácticas concretas que se desarrollan en las Empresas de Inserción, así como la comprensión y análisis de las lógicas seguidas por las entidades que las desarrollan. Para contextualizar el análisis emplearemos los desarrollos teóricos y metodológicos de L…
Fundaciones acogidas a la Ley 49/2002 e Impuesto sobre Sociedades: Indicadores de responsabilidad y transparencia tributaria
2015
Asistimos en la actualidad a una redefinición de las funciones del sector público, derivada tanto de la propia sostenibilidad de dicho agente como del papel que la sociedad civil reclama para sí. De esta forma se ha producido un desplazamiento desde la consideración inicial de las fundaciones como meras tenedoras de patrimonios estáticos hasta devenir hoy en día en auténticos operadores económicos de mercado, en el que intervendrán bien de forma directa bien a través de la participación en sociedades, con el objetivo de dar cumplimiento a los fines de interés general que les son propios. La función social así desarrollada supone el complemento, e incluso la sustitución, de la actividad rese…
Nickel induces intracellular calcium mobilization and pathophysiological responses in human cultured airway epithelial cells.
2009
Abstract Environmental exposure to nickel is associated to respiratory disorders and potential toxicity in the lung but molecular mechanisms remain incompletely explored. The extracellular Ca 2+ -sensing receptor (CaSR) is widely distributed and may be activated by divalent cations. In this study, we investigated the presence of CaSR in human cultured airway epithelial cells and its activation by nickel. Nickel transiently increased intracellular calcium (−log EC 50 = 4.67 ± 0.06) in A549 and human bronchial epithelial cells as measured by epifluorescence microscopy. Nickel (20 μM)-induced calcium responses were reduced after thapsigargin or ryanodine exposure but not by Ca 2+ -free medium…
