Posibles causas de la reducción de la población penitenciaria en España y Cataluña entre 2010 y 2013 : Efecto de la Ley Orgánica 5/2010 sobre esta reducción

Desde 1980 hasta 2010, la población penitenciaria no dejó de crecer. Sin embargo, desde 2010 esta tasa se está reduciendo. En este trabajo se trata de buscar una serie de explicaciones para este aumento, y para la posterior reducción. Se pone especialatención en la entrada en vigor de la Ley Orgánica 5/2010, que supuso una extensa reforma del Código Penal. Con esta Ley Orgánica, se introdujo la posibilidad de reducir en un grado ciertas conductas contra la salud pública, en forma de subtipo atenuado.Esto puede haber supuesto un efecto considerable sobre la reducción de las tasas de encarcelamiento. Para estudiar el efecto de este nuevo subtipo, se realiza una pequeña investigación cuantitativa sobre una muestra de sentencias por delitos contra la saludpública. Después, se muestran los resultados y se proponen nuevas líneas de investigación.

Enhanced Botrytis cinerea resistance of Arabidopsis plants grown in compost may be explained by increased expression of defense-related genes, as revealed by microarray analysis

Composts are the products obtained after the aerobic degradation of different types of organic matter waste and can be used as substrates or substrate/soil amendments for plant cultivation. There is a small but increasing number of reports that suggest that foliar diseases may be reduced when using compost, rather than standard substrates, as growing medium. The purpose of this study was to examine the gene expression alteration produced by the compost to gain knowledge of the mechanisms involved in compost-induced systemic resistance. A compost from olive marc and olive tree leaves was able to induce resistance against Botrytis cinerea in Arabidopsis, unlike the standard substrate, perlite. Microarray analyses revealed that 178 genes were differently expressed, with a fold change cut-off of 1, of which 155 were up-regulated and 23 were down-regulated in compost-grown, as against perlite-grown plants. A functional enrichment study of up-regulated genes revealed that 38 Gene Ontology terms were significantly enriched. Response to stress, biotic stimulus, other organism, bacterium, fungus, chemical and abiotic stimulus, SA and ABA stimulus, oxidative stress, water, temperature and cold were significantly enriched, as were immune and defense responses, systemic acquired resistance, secondary metabolic process and oxireductase activity. Interestingly, PR1 expression, which was equally enhanced by growing the plants in compost and by B. cinerea inoculation, was further boosted in compost-grown pathogen-inoculated plants. Compost triggered a plant response that shares similarities with both systemic acquired resistance and ABA-dependent/independent abiotic stress responses.

Mitochondrial dysfunction increases oxidative stress and decreases chronological life span in fission yeast

Background: Oxidative stress is a probable cause of aging and associated diseases. Reactive oxygen species (ROS) originate mainly from endogenous sources, namely the mitochondria. Methodology/Principal Findings: We analyzed the effect of aerobic metabolism on oxidative damage in Schizosaccharomyces pombe by global mapping of those genes that are required for growth on both respiratory-proficient media and hydrogen-peroxide-containing fermentable media. Out of a collection of approximately 2700 haploid yeast deletion mutants, 51 were sensitive to both conditions and 19 of these were related to mitochondrial function. Twelve deletion mutants lacked components of the electron transport chain. The growth defects of these mutants can be alleviated by the addition of antioxidants, which points to intrinsic oxidative stress as the origin of the phenotypes observed. These respiration-deficient mutants display elevated steady-state levels of ROS, probably due to enhanced electron leakage from their defective transport chains, which compromises the viability of chronologically-aged cells. Conclusion/Significance: Individual mitochondrial dysfunctions have often been described as the cause of diseases or aging, and our global characterization emphasizes the primacy of oxidative stress in the etiology of such processes.

An efficient algorithm to perform multiple testing in epistasis screening

Background: Research in epistasis or gene-gene interaction detection for human complex traits has grown over the last few years. It has been marked by promising methodological developments, improved translation efforts of statistical epistasis to biological epistasis and attempts to integrate different omics information sources into the epistasis screening to enhance power. The quest for gene-gene interactions poses severe multiple-testing problems. In this context, the maxT algorithm is one technique to control the false-positive rate. However, the memory needed by this algorithm rises linearly with the amount of hypothesis tests. Gene-gene interaction studies will require a memory proportional to the squared number of SNPs. A genome-wide epistasis search would therefore require terabytes of memory. Hence, cache problems are likely to occur, increasing the computation time. In this work we present a new version of maxT, requiring an amount of memory independent from the number of genetic effects to be investigated. This algorithm was implemented in C++ in our epistasis screening software MBMDR-3.0.3. We evaluate the new implementation in terms of memory efficiency and speed using simulated data. The software is illustrated on real-life data for Crohn’s disease. Results: In the case of a binary (affected/unaffected) trait, the parallel workflow of MBMDR-3.0.3 analyzes all gene-gene interactions with a dataset of 100,000 SNPs typed on 1000 individuals within 4 days and 9 hours, using 999 permutations of the trait to assess statistical significance, on a cluster composed of 10 blades, containing each four Quad-Core AMD Opteron(tm) Processor 2352 2.1 GHz. In the case of a continuous trait, a similar run takes 9 days. Our program found 14 SNP-SNP interactions with a multiple-testing corrected p-value of less than 0.05 on real-life Crohn’s disease (CD) data. Conclusions: Our software is the first implementation of the MB-MDR methodology able to solve large-scale SNP-SNP interactions problems within a few days, without using much memory, while adequately controlling the type I error rates. A new implementation to reach genome-wide epistasis screening is under construction. In the context of Crohn’s disease, MBMDR-3.0.3 could identify epistasis involving regions that are well known in the field and could be explained from a biological point of view. This demonstrates the power of our software to find relevant phenotype-genotype higher-order associations.

Multislice CT for assessing in-stent dimensions after left main coronary artery stenting: a comparison with three dimensional intravascular ultrasound

Objective: To evaluate the agreement between multislice CT (MSCT) and intravascular ultrasound (IVUS) to assess the in-stent lumen diameters and lumen areas of left main coronary artery (LMCA) stents. Design: Prospective, observational single centre study. Setting: A single tertiary referral centre. Patients: Consecutive patients with LMCA stenting excluding patients with atrial fibrillation and chronic renal failure. Interventions: MSCT and IVUS imaging at 912 months follow-up were performed for all patients. Main outcome measures: Agreement between MSCT and IVUS minimum luminal area (MLA) and minimum luminal diameter (MLD). A receiver operating characteristic (ROC) curve was plotted to find the MSCT cut-off point to diagnose binary restenosis equivalent to 6 mm2 by IVUS. Results: 52 patients were analysed. PassingBablok regression analysis obtained a β coefficient of 0.786 (0.586 to 1.071) for MLA and 1.250 (0.936 to 1.667) for MLD, ruling out proportional bias. The α coefficient was −3.588 (−8.686 to −0.178) for MLA and −1.713 (−3.583 to −0.257) for MLD, indicating an underestimation trend of MSCT. The ROC curve identified an MLA ≤4.7 mm2 as the best threshold to assess in-stent restenosis by MSCT. Conclusions: Agreement between MSCT and IVUS to assess in-stent MLA and MLD for LMCA stenting is good. An MLA of 4.7 mm2 by MSCT is the best threshold to assess binary restenosis. MSCT imaging can be considered in selected patients to assess LMCA in-stent restenosis

Anà lisi de competències en el Prà cticum de Pedagogia de la Universitat de Barcelona

El procés de convergència vers l"Espai Europeu d"Educació Superior (EEES), iniciat a partir de la declaració de Bolonya, col·loca l"assignatura del Pràcticum en una situació fonamental dins dels plans d"estudi de les titulacions. Això ens obliga a repensar-lo a partir dels nous paràmetres didàctics i organitzatius de l"EEES. El projecte de recerca Millora i reorientació del Pràcticum de Pedagogia vers l"EEES s"ha proposat una revisió del Pràcticum de Pedagogia de la UB des de diferents angles: l"estudi de l"ocupabilitat i la inserció laboral dels titulats de Pedagogia, la gestió i l"organització virtual de les tasques relacionades amb la coordinació del Pràcticum, així com l"elaboració d"un pla docent i un dossier de recursos per als tutors i tutores. En aquest article ens centrem exclusivament en el treball realitzat en relació a l"anàlisi de les competències que el Pràcticum de Pedagogia ha de permetre desenvolupar entre els estudiants. Aquest treball té especial vinculació amb l"elaboració d"un pla docent, però a la vegada és transversal als altres eixos esmentats.

Depression-like behavior is dependent on age in male SAMP8 mice

Aging is associated with an increased risk of depression in humans. To elucidate the underlying mechanisms of depression and its dependence on aging, here we study signs of depression in male SAMP8 mice. For this purpose, we used the forced swimming test (FST). The total floating time in the FST was greater in SAMP8 than in SAMR1 mice at 9 months of age; however, this difference was not observed in 12-month-old mice, when both strains are considered elderly. Of the two strains, only the SAMP8 animals responded to imipramine treatment. We also applied the dexamethasone suppression test (DST) and studied changes in the dopamine and serotonin (5-HT) uptake systems, the 5-HT2a/2c receptor density in the cortex, and levels of TPH2. The DST showed a significant difference between SAMR1 and SAMP8 mice at old age. SAMP8 exhibits an increase in 5-HT transporter density, with slight changes in 5-HT2a/2c receptor density. In conclusion, SAMP8 mice presented depression-like behavior that is dependent on senescence process, because it differs from SAMR1, senescence resistant strain.

Disseny d'un programa educatiu per prevenir les complicacions associades a l'alteració del perfil lipídic durant la gestació

L’embaràs és una situació especial en la vida de la dona que condiciona canvis en la seva fisiologia i en el desenvolupament d’un nou ésser. Entre aquests canvis fisiològics trobem l’augment dels nivells de colesterol i triglicèrids degut, majoritàriament, a l’augment de les hormones sexuals esteroidees i al metabolisme hepàtic i adipós alterat. Ara bé, cal mantenir aquests nivells dins d’uns límits per tal que no esdevinguin factor de risc de malalties futures, tant en la dona gestant com en el futur nadó.

Lo que callan los corpus, lo que afirman los cuepos [Pròleg]

La historia canónica de la belleza se ha representado en cuerpos femeninos heteropatriarcales estatuarios, producidos por discursos socioculturales que se afirman sobre el desposeimiento de la subjetividad y del deseo. La misma mirada, marcada por los prejuicios de sexo/género, nos ha legado una historia de violencia en que las mujeres solo pueden ser monstruosas metáforas del terror o víctimas inermes. Este libro parte justamente del alejamiento de estas bellezas estatuarias e invita a analizar esos ámbitos, no celebrativos, en que las mujeres —reales o de ficción— se afirman y se humanizan en su relación con el silencio, el dolor, la violencia y el horror. Desde la Edad Media hasta obras publicadas hace menos de veinte años, encontramos voces de mujer que se alejaron de la doxa de una u otra forma, a veces por el simple hecho de osar transformar su voz silenciada en palabra escrita. Lo que callan los corpus, lo que afirman los cuerpos presenta nueve visiones de violencia —física o simbólica, subjetiva u objetiva— ejercida sobre y por las mujeres a través del silencio, la ocultación, el encierro o la grotesca deformación de la verdadera realidad de su escritura y propone, así, nueve análisis que superan inercias para leer los corpus literarios más allá de cánones, con el cuerpo en primer plano.
