Geografías familiares bajo la dictadura franquista: exilio, clandestinidad, prisión

Este texto ahonda en las geografías políticas, sociales y familiares de Aurèlia Pijoan, la primera mujer que, médico de profesión, ha accedido a un cargo de representación municipal en Lleida. Casada con Luis Pérez García-Lago –secretario general del PSUC y la UGT en la Lleida de los años trenta y posteriormente máximo responsable del partido en el exilio mejicano-, continuó su compromiso a través de la Unión de Mujeres Españolas de México de la que llegó a convertirse en secretaria general. El artículo pretende, a la vez que reflexionar sobre el diálogo que se establece entre recuerdo y olvido, hacer visible la historia de los sin historia a partir de un centro de gravedad concreto, puesto que los itinerarios personales y familiares de Aurèlia Pijoan permiten recorrer las diversas caras del universo represivo franquista: exilio,clandestinidad y prisión.

Virus en Endodoncia

La infección endodóntica es la infección que afecta al sistema de conductos radiculares y, sin duda, es el principal agente etiológico de las periodontitis apicales. Además, de las bacterias patógenas endodónticas, se ha buscado en los últimos años asociar la presencia de virus en distintos tipos de patología endodóntica. Los virus que más se han buscado y asociado son los pertenecientes a la familia herpesvirus, los cuales se han encontrado presentes en patologías periapicales principalmente. Se ha buscado además, relacionar su presencia a patologías que cursan con mayor sintomatología, o que presentan a la imagen radiográfica destrucciones óseas periapicales mayores. El rol de los virus en las lesiones apicales de origen endodóntico está aún poco claro, se habla de efectos acumulativos a los de las bacterias, además de posibles inmunosupresiones locales que favorecerían el crecimiento y el efecto de estas últimas

In this project we present some background data about José Luis Sampedro and his works to point out the main reasons why we should translate them. We then offer a translation proposal for some selected chapters of the book La sonrisa etrusca in order to suggest a hypothetical translation job.

Andrés Pérez: una vida para el teatro

Si pienso en el teatro, más allá de una definición académica del término, pienso en una fiesta y un evento popular con participación “masiva”, pienso en un ritual, en un espacio sagrado y todo eso está presente en el trabajo de Andrés Pérez. Esta es mi verdad, la que voy a contar en este escrito, una verdad subjetiva sin duda y además una verdad que pasa no solo a través de lo efímero del teatro, sino también pasa por los recuerdos de mis testigos, por su memoria, gracias a las entrevistas que he realizado, a las notas de prensa y a los libros que he leído, la figura de Andrés Pérez ha tomado cuerpo y voz, por ejemplo con los videos que he logrado encontrar donde se hace presente. Otro elemento para mí interesante de la figura de Andrés es la popularidad que tiene en Chile y en Suramérica. Es muy conocido por haber trabajado casi siempre con personajes e historias marginales y por no haberse olvidado nunca de donde venía, llevando así el teatro a lugares pobres, por eso la gente lo ama: es una figura viva en la memoria de la sociedad chilena. La figura de Andrés Pérez, quedó grabada en el imaginario colectivo y se ha convertido en un héroe post dictadura y en plena época de reconciliación ha llegado al éxito. Fue el creador de un teatro masivo y popular, uniendo elementos del circo, magia, mimo, danza, teatro, música…

Venezuelan economic laboratory. The Case of the altruistic economy of Felipe Pérez Martí

Felipe Pérez Martí, who was the Venezuelan Minister of Planning and Development in the government of Hugo Chávez, proposes an economic model that he calls the altruistic economy or fourth way, which leads cooperative game theory to its logical extremes postulating a pure communism. Here we sustain that, first, it is impossible in the model of Pérez Martí to marginally allocate non-primary goods to those most in need or who most value them, facing a problem of defective economic calculation, and second, in order to achieve equality, he would have to replace his atomic local planners by a central planner, who would be unable to overcome the problem of imperfect and and incomplete information.

La inscripción registral de las fundaciones canónicas

La llibertat religiosa ha experimentat un desenvolupament important en l’Estat Espanyol des de la Constitució de 1978, donant lloc a un marc jurídic que avui en dia es segueix desenvolupant. Un instrument important per potenciar ’aquesta llibertat religiosa és el Registre d’entitats religioses en el que s’inscriuen totes les entitats que desenvolupen el seu culte a Espanya, i en especial les fundacions religioses de l’Esglèsia Catòlica.

La busca de Jorge Luis Borges: metáfora, metafísica y misticismo

El presente trabajo se propone analizar el influjo de la cultura islámica y, muy especialmente, de su vertiente mística, en tres relatos de la ‘serie árabe’ de Jorge Luis Borges: El Zahir, La busca de Averroes y El acercamiento a Almotásim, analizados en torno a los conceptos básicos de metáfora, metafísica y misticismo, respectivamente. El objeto de este estudio es clarificar las fuentes empleadas en dichos textos para desentrañar las actitudes ideológicas de raigambre árabe que comprenden y la particular interpretación que el autor hace de éstas, dando así una idea más completa y global de la poética borgesiana

Spain in Europe 2004-2008

In March of 2004, the Observatory of European Foreign Policy published a special monograph about Spain in Europe (1996-2004) in digital format. The objective of the monograph was to analyse Spain’s foreign policy agenda and strategy during the period of José María Aznar’s presidency. As the title suggests, one of the initial suppositions of the analysis is the Europeanization of Spanish foreign activities. Is that how it was? Did Aznar’s Spain see the world and relate to it through Brussels? The publication was well received, considering the number of visits received and above all the institutions which asked to link the publication to their web pages. Among these, the EUobserver published the introduction to the piece in English titled Aznar: thinking locally, acting in Europe (described by the EUobserver as a paper of utmost importance). The fact that the elections were held three days after the tragic events of the 11th of March dramatically increased interest in Spain and the implications for Europe. This publication is the second of its type, in this case analysing the period of the Zapatero government (2004-2008). Once again the starting premise (the Europeanization of the agenda and the methods employed) has been considered by the analysts. And once again the articles collected in this publication serve to “triangulate” the analysis. Spain and Europe are two vertices (more or less distant, in essence and in form) which the authors handle in their analysis of the case (third vertex).

España en Europa 2004-2008

En marzo de 2004 el Observatorio de Política Exterior Europea publicó, en versión digital, un monográfico especial sobre España en Europa (1996-2004). Su objetivo era analizar la agenda y la estrategia de España durante el período de José María Aznar en materia de relaciones internacionales. Como bien indicaba el título de aquella publicación, uno de los supuestos de partida del análisis era la europeización de la actividad internacional de España. ¿Era así?, ¿la España de Aznar veía el mundo y se aproximaba a él a través de Bruselas? Aquella publicación tuvo una buena acogida, a la vista de las visitas recibidas y sobre todo de las instituciones que nos pidieron vincular dicha publicación a sus páginas web y, entre ellas, hay que destacar que EUObserver publicó como comentario su artículo introductorio, en versión inglesa, Aznar: thinking locally, acting in Europe (calificado por EUObserver como lectura de máxima relevancia). El hecho de que las elecciones de 2004 se celebraran tres días después de los trágicos acontecimientos del 11-M hizo que el interés por España y por su proyección europea e internacional aumentara de manera destacada. La presente publicación constituye un segundo ejercicio de dicho tipo, en este caso para analizar el período del gobierno Zapatero (2004-2008). Una vez más, el supuesto de partida (la europeización de la agenda y del método) está en la mente de los analistas. Y una vez más los artículos recogidos en esta publicación hacen el ejercicio de “triangular” el análisis. España y Europa son dos vértices (más o menos alejados, en el fondo y en la forma) que los autores manejan en sus análisis de caso (tercer vértice)

Essential role of the N-terminal region of TFII-I in viability and behavior

Background: GTF2I codes for a general intrinsic transcription factor and calcium channel regulator TFII-I, with high and ubiquitous expression, and a strong candidate for involvement in the morphological and neuro-developmental anomalies of the Williams-Beuren syndrome (WBS). WBS is a genetic disorder due to a recurring deletion of about 1,55-1,83 Mb containing 25-28 genes in chromosome band 7q11.23 including GTF2I. Completed homozygous loss of either the Gtf2i or Gtf2ird1 function in mice provided additional evidence for the involvement of both genes in the craniofacial and cognitive phenotype. Unfortunately nothing is now about the behavioral characterization of heterozygous mice. Methods: By gene targeting we have generated a mutant mice with a deletion of the first 140 amino-acids of TFII-I. mRNA and protein expression analysis were used to document the effect of the study deletion. We performed behavioral characterization of heterozygous mutant mice to document in vivo implications of TFII-I in the cognitive profile of WBS patients. Results: Homozygous and heterozygous mutant mice exhibit craniofacial alterations, most clearly represented in homozygous condition. Behavioral test demonstrate that heterozygous mutant mice exhibit some neurobehavioral alterations and hyperacusis or odynacusis that could be associated with specific features of WBS phenotype. Homozygous mutant mice present highly compromised embryonic viability and fertility. Regarding cellular model, we documented a retarded growth in heterozygous MEFs respect to homozygous or wild-type MEFs. Conclusion: Our data confirm that, although additive effects of haploinsufficiency at several genes may contribute to the full craniofacial or neurocognitive features of WBS, correct expression of GTF2I is one of the main players. In addition, these findings show that the deletion of the fist 140 amino-acids of TFII-I altered it correct function leading to a clear phenotype, at both levels, at the cellular model and at the in vivo model.

Evidence for classification of c.1852_1853AA>GC in MLH1 as a neutral variant for Lynch syndrome

Background: Lynch syndrome (LS) is an autosomal dominant inherited cancer syndrome characterized by early onset cancers of the colorectum, endometrium and other tumours. A significant proportion of DNA variants in LS patients are unclassified. Reports on the pathogenicity of the c.1852_1853AA>GC (p.Lys618Ala) variant of the MLH1 gene are conflicting. In this study, we provide new evidence indicating that this variant has no significant implications for LS.Methods: The following approach was used to assess the clinical significance of the p.Lys618Ala variant: frequency in a control population, case-control comparison, co-occurrence of the p.Lys618Ala variant with a pathogenic mutation, co-segregation with the disease and microsatellite instability in tumours from carriers of the variant. We genotyped p.Lys618Ala in 1034 individuals (373 sporadic colorectal cancer [CRC] patients, 250 index subjects from families suspected of having LS [revised Bethesda guidelines] and 411 controls). Three well-characterized LS families that fulfilled the Amsterdam II Criteria and consisted of members with the p.Lys618Ala variant were included to assess co-occurrence and co-segregation. A subset of colorectal tumour DNA samples from 17 patients carrying the p.Lys618Ala variant was screened for microsatellite instability using five mononucleotide markers.Results: Twenty-seven individuals were heterozygous for the p.Lys618Ala variant; nine had sporadic CRC (2.41%), seven were suspected of having hereditary CRC (2.8%) and 11 were controls (2.68%). There were no significant associations in the case-control and case-case studies. The p.Lys618Ala variant was co-existent with pathogenic mutations in two unrelated LS families. In one family, the allele distribution of the pathogenic and unclassified variant was in trans, in the other family the pathogenic variant was detected in the MSH6 gene and only the deleterious variant co-segregated with the disease in both families. Only two positive cases of microsatellite instability (2/17, 11.8%) were detected in tumours from p.Lys618Ala carriers, indicating that this variant does not play a role in functional inactivation of MLH1 in CRC patients.Conclusions: The p.Lys618Ala variant should be considered a neutral variant for LS. These findings have implications for the clinical management of CRC probands and their relatives.

X-chromosome tiling path array detection of copy number variants in patients with chromosome X-linked mental retardation

Background: Aproximately 5–10% of cases of mental retardation in males are due to copy number variations (CNV) on the X chromosome. Novel technologies, such as array comparative genomic hybridization (aCGH), may help to uncover cryptic rearrangements in X-linked mental retardation (XLMR) patients. We have constructed an X-chromosome tiling path array using bacterial artificial chromosomes (BACs) and validated it using samples with cytogenetically defined copy number changes. We have studied 54 patients with idiopathic mental retardation and 20 controls subjects. Results: Known genomic aberrations were reliably detected on the array and eight novel submicroscopic imbalances, likely causative for the mental retardation (MR) phenotype, were detected. Putatively pathogenic rearrangements included three deletions and five duplications (ranging between 82 kb to one Mb), all but two affecting genes previously known to be responsible for XLMR. Additionally, we describe different CNV regions with significant different frequencies in XLMR and control subjects (44% vs. 20%). Conclusion:This tiling path array of the human X chromosome has proven successful for the detection and characterization of known rearrangements and novel CNVs in XLMR patients.

Genetic and genomic analysis modeling of germline c-MYC overexpression and cancer susceptibility

Background: Germline genetic variation is associated with the differential expression of many human genes. The phenotypic effects of this type of variation may be important when considering susceptibility to common genetic diseases. Three regions at 8q24 have recently been identified to independently confer risk of prostate cancer. Variation at 8q24 has also recently been associated with risk of breast and colorectal cancer. However, none of the risk variants map at or relatively close to known genes, with c-MYC mapping a few hundred kilobases distally. Results: This study identifies cis-regulators of germline c-MYC expression in immortalized lymphocytes of HapMap individuals. Quantitative analysis of c-MYC expression in normal prostate tissues suggests an association between overexpression and variants in Region 1 of prostate cancer risk. Somatic c-MYC overexpression correlates with prostate cancer progression and more aggressive tumor forms, which was also a pathological variable associated with Region 1. Expression profiling analysis and modeling of transcriptional regulatory networks predicts a functional association between MYC and the prostate tumor suppressor KLF6. Analysis of MYC/Myc-driven cell transformation and tumorigenesis substantiates a model in which MYC overexpression promotes transformation by down-regulating KLF6. In this model, a feedback loop through E-cadherin down-regulation causes further transactivation of c-MYC.Conclusion: This study proposes that variation at putative 8q24 cis-regulator(s) of transcription can significantly alter germline c-MYC expression levels and, thus, contribute to prostate cancer susceptibility by down-regulating the prostate tumor suppressor KLF6 gene.

Reassessing the role of mitochondrial DNA mutations in autism spectrum disorder

Background: There is increasing evidence that impairment of mitochondrial energy metabolism plays an important role in the pathophysiology of autism spectrum disorders (ASD; OMIM number: 209850). A significant proportion of ASD cases display biochemical alterations suggestive of mitochondrial dysfunction and several studies have reported that mutations in the mitochondrial DNA (mtDNA) molecule could be involved in the disease phenotype. Methods: We analysed a cohort of 148 patients with idiopathic ASD for a number of mutations proposed in the literature as pathogenic in ASD. We also carried out a case control association study for the most common European haplogroups (hgs) and their diagnostic single nucleotide polymorphisms (SNPs) by comparing cases with 753 healthy and ethnically matched controls.Results: We did not find statistical support for an association between mtDNA mutations or polymorphisms and ASD.Conclusions: Our results are compatible with the idea that mtDNA mutations are not a relevant cause of ASD and the frequent observation of concomitant mitochondrial dysfunction and ASD could be due to nuclear factors influencing mitochondrion functions or to a more complex interplay between the nucleus and the mitochondrion/mtDNA.
