2014
“Mujer y representación política institucional en la Comunidad Valenciana. 1977-1995. Diputadas, ministras y cargos institucionales” es la primera parte de un trabajo de documentación para un capítulo de “La democracia en la Comunidad Valenciana. Partidos, elites políticas, elecciones y programas políticos”. “Mujer, poder político y democracia paritaria”. Se recoge el papel de la mujer en la vida política de la Comunidad Valenciana en la democracia actual, desde 1977. Es documentación sin elaborar, pero que aporta datos de la presencia de la mujer en las instituciones, partidos y sindicatos. Cuando este completa será una parte de la investigación referida, y de la que ya hay dos publicacion…
New insights regarding Acinetobacter genomic island-related elements
2020
The objective of this study was to mobilize the Acinetobacter genomic island 1-A (AGI1-A) from Enterobacter hormaechei EclCSP2185 (E. cloacae complex) and to search for the distribution and structure of AGI1-related elements in the NCBI database. AGI1-A was transferred to Escherichia coli. Analysis of the attachment (att) sites could locate the possible recombination crossover in the att sequences at position 10-11 (GG) in the last 18 bp of trmE. In silico detection of AGI backbones in the wgs database identified AGI variants in Salmonella enterica (83 strains), Vibrio cholerae (33), E. hormaechei (12), Acinetobacter baumannii (2), most belonging to prevalent clones (ST40, ST69, ST114 and S…
Los años de la hegemonía socialista. 1983-1995
2007
"Los años de la hegemonía socialista. 1983-1995" es un capítulo escrito por Benito Sanz en la obra colectiva editada por el diario Levante: "La Gran Historia de la Comunitat Valenciana. La democracia reconquistada. De la Transición a la normalización democrática (1975-2008)", tomo 10, dirigida por Francesc A. Martínez y Antonio Laguna. Valencia 2007. "Los años de la hegemonía socialista. 1983-1995" recoge las tres legislaturas en las que el PSPV-PSOE gobernó de forma hegemónica casi todas las instituciones publicas de España, la Comunidad Valenciana, así como las tres diputaciones provinciales, los tres ayuntamientos de las capitales de las provincias y la gran mayoría de los municipios.

Erratum: By promoting cell differentiation, miR-100 sensitizes basal-like breast cancer stem cells to hormonal therapy
2019
Basal-like breast cancer is an aggressive tumor subtype with a poor response to conventional therapies. Tumor formation and relapse are sustained by a cell subset of Breast Cancer Stem Cells (BrCSCs). Here we show that miR-100 inhibits maintenance and expansion of BrCSCs in basal-like cancer through Polo-like kinase1 (Plk1) down-regulation. Moreover, miR-100 favors BrCSC differentiation, converting a basal like phenotype into luminal. It induces the expression of a functional estrogen receptor (ER) and renders basal-like BrCSCs responsive to hormonal therapy. The key role played by miR-100 in breast cancer free-survival is confirmed by the analysis of a cohort of patients' tumors, which sho…
Stable changes in CD4+ T lymphocyte miRNA expression after exposure to HIV-1
2012
Abstract MicroRNAs (miRNAs) inhibit HIV-1 expression by either modulating host innate immunity or by directly interfering with viral mRNAs. We evaluated the expression of 377 miRNAs in CD4+ T cells from HIV-1 élite long-term nonprogressors (éLTNPs), naive patients, and multiply exposed uninfected (MEU) patients, and we observed that the éLTNP patients clustered with naive patients, whereas all MEU subjects grouped together. The discriminatory power of miRNAs showed that 21 miRNAs significantly differentiated éLTNP from MEU patients and 23 miRNAs distinguished naive from MEU patients, whereas only 1 miRNA (miR-155) discriminated éLTNP from naive patients. We proposed that miRNA expression ma…
Downregulation of miRNA17-92 cluster marks Vγ9Vδ2 T cells from patients with rheumatoid arthritis
2018
Abstract Background We aimed to evaluate the phenotype, function, and microRNA (miRNA)17–92 cluster expression in Vγ9Vδ2 T-cell subsets and the correlation with immune response in rheumatoid arthritis (RA) patients. Methods Peripheral blood from 10 early RA untreated patients and 10 healthy donors (HD) was obtained. Polyclonal Vγ9Vδ2 T-cell lines were generated and analysed by flow cytometry. Analysis of miRNA17–92 cluster expression was performed by real-time polymerase chain reaction (RT-PCR), and expression of mRNA target genes was also studied. Results A remarkable change in the distribution of Vγ9Vδ2 T-cell functional subsets was observed in the peripheral blood of RA patients compared…
The effect of longitudinal chromatic aberration on the lag of accommodation and depth of field.
2016
Purpose Longitudinal chromatic aberration is present in all states of accommodation and may play a role in the accommodation response and the emmetropisation process. We study the change of the depth of field (DOFi) with the state of accommodation, taking into account the longitudinal chromatic aberration. Methods Subjective DOFi was defined as the range of defocus beyond which the blur of the target (one line of optotypes of 0.1 logMAR shown on a black-and-white microdisplay, seen through different colour filters) was perceived as objectionable. The subject's eye was paralysed and different, previously-measured accommodative states (corresponding to the accommodative demands of 0D, 2D and …
The impact of rear-view mirror distance and curvature on judgements relevant to road safety
2011
We report two experiments that investigate the impact of rear-view mirror distance and curvature on distance, spacing, and time-to-contact (TTC) judgements. The variation in mirror distance had a significant effect on TTC judgements, but only marginally influenced distance and spacing estimations. As mirror distance increased, TTC was overestimated, which is potentially dangerous. Control conditions with identical visual angles across different mirror distances revealed that effects were not solely caused by variation in visual angle. The impact of mirror curvature moderated the effect. While observers were unable to compensate for the mirror distance effect, they could do so for the distor…
Convex rear view mirrors compromise distance and time-to-contact judgements
2007
Convex rear view mirrors increasingly replace planar mirrors in automobiles. While increasing the field of view, convex mirrors are also taken to increase distance estimates and thereby reduce safety margins. However, this study failed to replicate systematic distance estimation errors in a real world setting. Whereas distance estimates were accurate on average, convex mirrors lead to significantly more variance in distance and spacing estimations. A second experiment explored the effect of mirrors on time-to-contact estimations, which had not been previously researched. Potential effects of display size were separated from effects caused by distortion in convex mirrors. Time-to-contact est…
Encoding of human action in Broca's area.
2009
International audience; Broca's area has been considered, for over a century, as the brain centre responsible for speech production. Modern neuroimaging and neuropsychological evidence have suggested a wider functional role is played by this area. In addition to the evidence that it is involved in syntactical analysis, mathematical calculation and music processing, it has recently been shown that Broca's area may play some role in language comprehension and, more generally, in understanding actions of other individuals. As shown by functional magnetic resonance imaging, Broca's area is one of the cortical areas activated by hand/mouth action observation and it has been proposed that it may …
