Postmodernism in Angela Carter’s Short Fiction: A Žižekian Approach
The aim of this dissertation is to contribute to the academic dispute over the emancipatory potential of Angela Carter‘s fiction by examining the way in which her short fiction re-imagines and either reproduces or subverts the ideology at work in patriarchy. The relevance that the category ―postmodernism‖ has had for the critical reception of Carter‘s work determines this dissertation‘s three-part structure. The first part provides an overview of the standard theoretical perspectives that define postmodernism as a frame of ideas and as a literary practice and that, as such, have had a direct influence on the assessment of the political potential of Carter‘s fiction. Part II focuses on Slavoj Žižek‘s non-standard account of postmodernism, an approach that reasserts the subversive character of postmodernist cultural productions. Part III analyses a corpus of seven short narratives from Carter‘s four collections and examines the extent to which Žižek‘s unorthodox view of postmodernism sheds new light on the emancipatory potential of their representation of social reality, sexual difference and the human condition
Does Progressive Introduction of Benznidazole Reduce the Chance of Adverse Events in the Treatment of Chagas Disease?
In this retrospective
cohort study, we aimed to assess whether introducing
benznidazole at escalating doses reduces the probability of
adverse events or treatment discontinuation compared with a
full-dose scheme. We collected data from patients who had
chronic " - " infection and underwent treatment from July 2008
to January 2017 in a referral center in Madrid. Dose was
adjusted to body weight (5 mg/kg/day), with treatment
introduction with full dose or escalating dose according to
local consensus and protocols. Among the 62 patients treated,
benznidazole was introduced at full dose in 28 patients and on
escalating dose in the remaining 34. We found no statistical
differences in the number of adverse events, treatment
discontinuations, days of treatment, or sociodemographic
profiles. There is insufficient evidence to support escalating
dose as a strategy for reducing the adverse effects of
benznidazole. Further research is needed to evaluate this
strategy
“I feel guilty”. Exploring guilt-related dynamics in family caregivers of people with dementia
Objectives: Family caregivers of people with dementia often report feelings of guilt. However, the number of studies analyzing guilt and the factors associated with its appearance are scarce. The aim of this study is to explore the subjective experience of guilt in the family care of people with dementia. Methods: A qualitative analysis of the narratives of 13 family caregivers of people with dementia about their feelings of guilt was done. Results: Seven categories for understanding guilt in caregiving were obtained: guilt derived from actions themselves; guilt derived from one’s limitations; guilt for feeling negative emotions; guilt associated with the change in the relationship with the person cared for; guilt for neglecting other areas; guilt induced by the person cared for, and guilt induced by others. The results showed the existence of cases in which guilt is absent by distress-avoiding processes. Conclusions: Guilt is a relevant variable in understanding caregiver distress, and its analysis is necessary for therapeutic work in the field of care. Clinical implications: Psychological interventions aimed at family caregivers should include specific techniques in order to address guilt feelings.The study was supported by the Spanish Ministry of Economy and Competiveness (grants PSI2015-65,152-C2-1-R and PSI2015-65,152-C2-2-R
Effects of Enteromyxum spp. (Myxozoa) infection in the regulation of intestinal E‐cadherin: Turbot against gilthead sea bream
This is the peer reviewed version of the following article: Ronza, P, Estensoro, I, Bermúdez, R, et al. Effects of Enteromyxum spp. (Myxozoa) infection in the regulation of intestinal E‐cadherin: Turbot against gilthead sea bream. J Fish Dis. 2020; 43: 337– 346, which has been published in final form at https://doi.org/10.1111/jfd.13130. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived VersionsEnteromyxoses are relevant diseases for turbot and gilthead sea bream aquaculture. The myxozoan parasites invade the intestinal mucosa, causing a cachectic syndrome associated with intestinal barrier alteration; nonetheless, their pathological impact is different. Turbot infected by Enteromyxum scophthalmi develop more severe intestinal lesions, reaching mortality rates of 100%, whereas in E. leei‐infected gilthead sea bream, the disease progresses slowly, and mortality rates are lower. The mechanisms underlying the different pathogenesis are still unclear. We studied the distribution and expression changes of E‐cadherin, a highly conserved protein of the adherens junctions, in the intestine of both species by immunohistochemistry and quantitative PCR, using the same immunohistochemical protocol and common primers. The regular immunostaining pattern observed in control fish turned into markedly irregular in parasitized turbot, showing an intense immunoreaction at the host–parasite interface. Nevertheless, E‐cadherin gene expression was not significantly modulated in this species. On the contrary, no evident changes in the protein distribution were noticed in gilthead sea bream, whereas a significant gene downregulation occurred in advanced infection. The results contribute to the understanding of the different host–parasite interactions in enteromyxoses. Host and parasite cells appear to establish diverse relationships in these species, which could underlie the different pathological pictureThis work has been funded by the Spanish Ministry of Economy and Competitiveness and the European Regional Development Fund (ERDF) through the projects AGL2015‐67039‐C3‐1‐R, AGL2015‐67039‐C3‐3‐R and AGL‐2013‐48560‐R and by the Horizon 2020 Framework Programme through ParaFishControl Project (634429).

Transcriptomic and Metabolomic Response to High Light in the Charophyte Alga Klebsormidium nitens
The characterization of the molecular mechanisms, such as high light irradiance resistance, that allowed plant terrestralization is a cornerstone in evolutionary studies since the conquest of land by plants played a pivotal role in life evolution on Earth. Viridiplantae or the green lineage is divided into two clades, Chlorophyta and Streptophyta, that in turn splits into Embryophyta or land plants and Charophyta. Charophyta are used in evolutionary studies on plant terrestralization since they are generally accepted as the extant algal species most closely related to current land plants. In this study, we have chosen the facultative terrestrial early charophyte alga Klebsormidium nitens to perform an integrative transcriptomic and metabolomic analysis under high light in order to unveil key mechanisms involved in the early steps of plants terrestralization. We found a fast chloroplast retrograde signaling possibly mediated by reactive oxygen species and the inositol polyphosphate 1-phosphatase (SAL1) and 3′-phosphoadenosine-5′-phosphate (PAP) pathways inducing gene expression and accumulation of specific metabolites. Systems used by both Chlorophyta and Embryophyta were activated such as the xanthophyll cycle with an accumulation of zeaxanthin and protein folding and repair mechanisms constituted by NADPH-dependent thioredoxin reductases, thioredoxin-disulfide reductases, and peroxiredoxins. Similarly, cyclic electron flow, specifically the pathway dependent on proton gradient regulation 5, was strongly activated under high light. We detected a simultaneous co-activation of the non-photochemical quenching mechanisms based on LHC-like stress related (LHCSR) protein and the photosystem II subunit S that are specific to Chlorophyta and Embryophyta, respectively. Exclusive Embryophyta systems for the synthesis, sensing, and response to the phytohormone auxin were also activated under high light in K. nitens leading to an increase in auxin content with the concomitant accumulation of amino acids such as tryptophan, histidine, and phenylalanine.España Ministerio de Ciencia e Innovación MINOTAUR (BIO2017-84066-R
Genetic and functional analysis of biogenic amine production capacity among starter and non-starter lactic acid bacteria isolated from artisanal cheeses
© 2015, Springer-Verlag Berlin Heidelberg. This work reports the capacity of 137 strains of starter and non-starter LAB belonging to nine species of the genera Lactobacillus, Lactococcus, Streptococcus and Leuconostoc (all isolated from artisanal cheeses) to produce histamine, tyramine, putrescine and β-phenylethylamine, the biogenic amines (BA) most commonly found in dairy products. Production assays were performed in liquid media supplemented with the appropriate precursor amino acid; culture supernatants were then tested for BA by (U)HPLC. In addition, the presence of key genes involved in the biosynthetic pathways of the target BA, including the production of putrescine via the agmatine deiminase pathway, was assessed by PCR. Twenty strains were shown to have genes involved in the synthesis of BA; these belonged to the species Lactobacillus brevis (4), Lactobacillus curvatus (3), Lactococcus lactis (11) and Streptococcus thermophilus (2). With the exception of the two S. thermophilus strains, all those possessing genes involved in BA production synthesized the corresponding compound. Remarkably, all the putrescine-producing strains used the agmatine deiminase pathway. Four L. brevis and two L. curvatus strains were found able to produce both tyramine and putrescine. There is increasing interest in the use of autochthonous LAB strains in starter and adjunct cultures for producing dairy products with ‘particular geographic indication’ status. Such strains should not produce BA; the present results show that BA production capacity should be checked by (U)HPLC and PCR.This work was funded by the Ministry of Economy and Competitiveness, Spain (AGL2013-45431-R), the Fundación para el Fomento en Asturias de la Investigación Científica Aplicada y la Tecnología (FICYT), cofunded by FEDER (GRUPIN14-137) and the INIA (RM2011-00005-00-00).Peer Reviewe
Exploring genetic factors involved in huntington disease age of onset. E2F2 as a new potential modifier gene
Age of onset (AO) of Huntington disease (HD) is mainly determined by the length of the CAG repeat expansion (CAGexp) in exon 1 of the HTT gene. Additional genetic variation has been suggested to contribute to AO, although the mechanism by which it could affect AO is presently unknown. The aim of this study is to explore the contribution of candidate genetic factors to HD AO in order to gain insight into the pathogenic mechanisms underlying this disorder. For that purpose, two AO definitions were used: the earliest age with unequivocal signs of HD (earliest AO or eAO), and the first motor symptoms age (motor AO or mAO). Multiple linear regression
analyses were performed between genetic variation within 20 candidate genes and eAO or mAO, using DNA and clinical information of 253 HD patients from REGISTRY project. Gene expression analyses were carried out by RT-qPCR with an independent sample of 35 HD patients from Basque Country Hospitals. We found suggestive association signals between HD eAO and/or mAO and genetic variation within the E2F2, ATF7IP, GRIN2A, GRIN2B, LINC01559, HIP1 and GRIK2 genes. Among them, the most significant was the association between eAO and rs2742976, mapping to the promoter region of E2F2 transcription factor.
Furthermore, rs2742976 T allele patient carriers exhibited significantly lower lymphocyte E2F2 gene expression, suggesting a possible implication of E2F2-dependent transcriptional activity in HD pathogenesis. Thus, E2F2 emerges as a new potential HD AO modifier factor

Here we update this outbreak, analyze near full-length genomes, determine phylogenetic relationships, and estimate its origin. For this study, we used sequences of HIV-1 protease-reverse transcriptase and env V3 region, and for 17 samples, near full-length genome sequences were obtained. Phylogenetic analyses were performed via maximum likelihood. Locations and times of most recent common ancestors were estimated using Bayesian inference. Among samples analyzed by us, 100 HIV-1 F1 subsubtype infections of monophyletic origin were diagnosed in Spain, including 88 in Galicia and 12 in four other regions. Most viruses (n = 90) grouped in a subcluster (Galician subcluster), while 7 from Valladolid (Central Spain) grouped in another subcluster. At least 94 individuals were sexually-infected males and at least 71 were MSM. Seventeen near full-length genomes were uniformly of F1 subsubtype. Through similarity searches and phylogenetic analyses, we identified 18 viruses from four other Western European countries [Switzerland (n = 8), Belgium (n = 5), France (n = 3), and United Kingdom (n = 2)] and one from Brazil, from samples collected in 2005?2011, which branched within the subtype F cluster, outside of both Spanish subclusters, most of them corresponding to recently infected individuals. The most probable geographic origin and age of the Galician subcluster was Ferrol, Northwest Galicia, around 2007, while the Western European cluster probably emerged in Switzerland around 2002. In conclusion, a recently expanded HIV-1 subtype F cluster, the largest non-subtype B cluster reported in Western Europe, continues to spread among MSM in Spain; this cluster is part of a larger cluster with a wide geographic circulation in diverse Western European countries.Publisher PDFPeer reviewe

COVID-19 outbreaks in a transmission control scenario: challenges posed by social and leisure activities, and for workers in vulnerable conditions, Spain, early summer 2020
Severe acute respiratory syndrome coronavirus 2 community-wide transmission declined in Spain by early May 2020, being replaced by outbreaks and sporadic cases. From mid-June to 2 August, excluding single household outbreaks, 673 outbreaks were notified nationally, 551 active (>6,200 cases) at the time. More than half of these outbreaks and cases coincided with: (i) social (family/friends’ gatherings or leisure venues) and (ii) occupational (mainly involving workers in vulnerable conditions) settings. Control measures were accordingly applied
