RESUMEN

The economic crisis of 2008 severely affected the welfare states. As the economic situation of a country worsens, the resources that the public administration can devote to improve the situation of the people also decrease, endangering the advancement of those in a disadvantaged situation. People who have always lived in poverty, besides having their opportunities reduced, also face negative public views that affect the perceived legitimacy of such public aid, which can in turn be a mechanism for perpetuating their situation. Two studies (N = 252 and N = 266) analyse how a person in persistent poverty is perceived compared to a person in poverty due to the crisis-a circumstantial poverty. We also study some feasible mechanisms underlying this different perception, as well as their effects on attitudes toward social protection policies. In Study 1, results indicated that people showed more favourable attitudes toward social protection policies when they perceived someone in poverty due to the crisis, compared to the target who had been in poverty all his/her life. Individualistic attributions for poverty mediated this effect: when people think of someone in persistent poverty, they make more individualistic attributions concerning their situation, which leads to worse attitudes toward social protection policies. Identification with the group moderates this relation. Furthermore, Study 2 showed that participants perceive people who are in poverty because of economic crisis as more deserving of help than people who have always been poor. Some theoretical and practical implications for intergroup relations and public policy are discussed.

RESUMEN

OBJECTIVE: We aimed to investigate the prevalence of TOR1A, GNAL and THAP1 variants as the cause of dystonia in a cohort of Spanish patients with isolated dystonia and in the literature. METHODS: A population of 2028 subjects (including 1053 patients with different subtypes of isolated dystonia and 975 healthy controls) from southern and central Spain was included. The genes TOR1A, THAP1 and GNAL were screened using a combination of high-resolution melting analysis and direct DNA resequencing. In addition, an extensive literature search to identify original articles (published before 10 August 2020) reporting mutations in TOR1A, THAP1 or GNAL associated to dystonia was performed. RESULTS: Pathogenic or likely pathogenic variants in TOR1A, THAP1 and GNAL were identified in 0.48%, 0.57% and 0.29% of our patients, respectively. Five patients carried the variation p.Glu303del in TOR1A. A very rare variant in GNAL (p.Ser238Asn) was found as a putative risk factor for dystonia. In the literature, variations in TOR1A, THAP1 and GNAL accounted for about 6%, 1.8% and 1.1% of published dystonia patients, respectively. CONCLUSIONS: There is a different genetic contribution to dystonia of these three genes in our patients (about 1.3% of patients) and in the literature (about 3.6% of patients), probably due the high proportion of adult-onset cases in our cohort. As regards age at onset, site of dystonia onset, and final distribution, in our population there is a clear differentiation between DYT-TOR1A and DYT-GNAL, with DYT-THAP1 likely to be an intermediate phenotype.

RESUMEN

Tocopherols are important antioxidants exclusively produced in plastids that protect the photosynthetic apparatus from oxidative stress. These compounds with vitamin E activity are also essential dietary nutrients for humans. Although the tocopherol biosynthetic pathway has been elucidated, the mechanisms that regulate tocopherol production and accumulation remain elusive. Here, we investigated the regulatory mechanism underlying tocopherol biosynthesis during ripening in tomato fruits, which are an important source of vitamin E. Our results show that ripening under light conditions increases tocopherol fruit content in a phytochrome-dependent manner by the transcriptional regulation of biosynthetic genes. Moreover, we show that light-controlled expression of the GERANYLGERANYL DIPHOSPHATE REDUCTASE (SlGGDR) gene, responsible for the synthesis of the central tocopherol precursor phytyl diphosphate, is mediated by PHYTOCHROME-INTERACTING FACTOR 3 (SlPIF3). In the absence of light, SlPIF3 physically interacts with the promoter of SlGGDR, down-regulating its expression. By contrast, light activation of phytochromes prevents the interaction between SlPIF3 and the SlGGDR promoter, leading to transcriptional derepression and higher availability of the PDP precursor for tocopherol biosynthesis. The unraveled mechanism provides a new strategy to manipulate fruit metabolism towards improving tomato nutritional quality.

RESUMEN

Differences between groups in socio-economic status (SES) are becoming more salient nowadays. In this context, we examined the animalistic and mechanistic dehumanization that both low and high-SES groups may experience respectively by conducting three studies. In study 1, we manipulated the SES of two fictitious groups (low vs. high-SES) and measured the humanity ascribed to them. Results showed that the low-SES group was animalized in comparison with the high-SES group, which was mechanized. In study 2, we manipulated the humanity of two fictitious groups by describing them as animals or machines and measured the perceived SES of the groups. Participants tended to attribute lower SES to the group described as animals and higher SES to the group described as machines. Finally, in study 3, we used an Implicit Association Test to replicate the results of studies 1 and 2. Taken together, these studies show that low-SES groups are considered as animal-like whereas high-SES groups are seen as robot-like. We discuss the implications of these findings in relation to the justification of income inequality within our society.

RESUMEN

Profound metabolic and structural changes are required for fleshy green fruits to ripen and become colorful and tasty. In tomato (Solanum lycopersicum), fruit ripening involves the differentiation of chromoplasts, specialized plastids that accumulate carotenoid pigments such as ß-carotene (pro-vitamin A) and lycopene. Here, we explored the role of the plastidial Clp protease in chromoplast development and carotenoid accumulation. Ripening-specific silencing of one of the subunits of the Clp proteolytic complex resulted in ß-carotene-enriched fruits that appeared orange instead of red when ripe. Clp-defective fruit displayed aberrant chromoplasts and up-regulated expression of nuclear genes encoding the tomato homologs of Orange (OR) and ClpB3 chaperones, most probably to deal with misfolded and aggregated proteins that could not be degraded by the Clp protease. ClpB3 and OR chaperones protect the carotenoid biosynthetic enzymes deoxyxylulose 5-phosphate synthase and phytoene synthase, respectively, from degradation, whereas OR chaperones additionally promote chromoplast differentiation by preventing the degradation of carotenoids such as ß-carotene. We conclude that the Clp protease contributes to the differentiation of chloroplasts into chromoplasts during tomato fruit ripening, acting in co-ordination with specific chaperones that alleviate protein folding stress, promote enzyme stability and accumulation, and prevent carotenoid degradation.

RESUMEN

AIM: This study evaluated the effect of ≥6 months of transdermal rotigotine on non-motor and motor symptoms of patients with advanced Parkinson's disease. MATERIALS AND METHODS: The study was conducted in Spain between September 2011 and December 2012 (ClinicalTrials.gov: NCT01504529). The primary efficacy variable was the change from baseline in non-motor symptoms, as assessed by changes in Parkinson's Disease Non-Motor Symptoms Questionnaire total scores at 6 months. Secondary endpoints included the assessment of motor symptoms by Unified Parkinson's Disease Rating Scale III scores. RESULTS: Data from 378 patients (mean age: 70.2 years; 56.9% male) with Parkinson's disease receiving rotigotine from were collected. Mean disease duration was 6.1 years, and mean rotigotine treatment duration was 45.6 months. Rotigotine reduced non-motor symptoms by 14.6% (mean change from baseline in Parkinson's Disease Non-Motor Symptoms Questionnaire: -1.5 ± 3.4; p < 0.0001). The majority of patients (58.2%) had improved non-motor symptoms at 6 months. Comparing the baseline versus study end, fewer patients experienced events in the urinary (78.6% vs. 73.3%; p = 0.0066), sleep (82.8% vs. 72.8%; p < 0.0001) and mood/cognition (77.3% vs. 66.4%; p < 0.0001) domains of the Parkinson's Disease Non-Motor Symptoms Questionnaire. Mean motor symptoms were reduced from baseline by 8.0% (mean change from baseline in Unified Parkinson's Disease Rating Scale III: -2.6 ± 8.0; p < 0.0001). CONCLUSIONS: In clinical practice in Spain, rotigotine may be an effective treatment to reduce the non-motor and motor symptoms in patients with advanced Parkinson's disease.

RESUMEN

Light is a major regulator of plant growth and development by antagonizing gibberellins (GA), and we provide evidence for a role of light perception and GA in seed coat formation and seed tolerance to deterioration. We have identified two activation-tagging mutants of Arabidopsis thaliana, cog1-2D and cdf4-1D, with improved seed tolerance to deterioration linked to increased expression of COG1/DOF1.5 and CDF4/DOF2.3, respectively. These encode two homologous DOF transcription factors, with COG1 most highly expressed in seeds. Improved tolerance to seed deterioration was reproduced in transgenic plants overexpressing these genes, and loss of function from RNA interference resulted in opposite phenotypes. Overexpressions of COG1 and CDF4 have been described to attenuate various light responses mediated by phytochromes. Accordingly, we found that phyA and phyB mutants exhibit increased seed tolerance to deterioration. The phenotype of tolerance to deterioration conferred by gain of function of COG1 and by loss of function of phytochromes is of maternal origin, is also observed under natural aging conditions and correlates with a seed coat with increased suberin and reduced permeability. In developing siliques of the cog1-2D mutant the expression of the GA biosynthetic gene GA3OX3 and levels of GA1 are higher than in the wild type. These results explain the antagonism between phytochromes and COG1 in terms of the inhibition and the activation, respectively, of GA action.

RESUMEN

BACKGROUND: A recent genome-wide association study (GWAS) has identified a putative association, not statistically confirmed, of cervical dystonia within several regions in a British population. Hence, the authors proposed dysfunction of the ion channel NALCN (for sodium leak channel, nonselective) as a plausible cause of cervical dystonia. The objective of our study was to investigate the association of five single nucleotide polymorphisms (SNPs) previously reported with high signals as putative genetic risk factors for cervical dystonia in a British GWAS, including two located in the NALCN gene region. METHODS: We performed a case-control association study in a Spanish population. The SNPs selected for genotyping were two SNPS in the NALCN gene (rs61973742 and rs1338041), one SNP in the OR4X2 gene (rs67863238), one SNP in the COL4A1 region (rs619152), and one intergenic SNP (rs1249277). Genomic DNA was collected from 252 patients with cervical dystonia, with a mean age of 55.3 ± 14.1 years (mean age at onset, 43.5 ± 15.7 years), and 342 unrelated control subjects with a mean age of 56.3 ± 14.3 years. Genotyping of SNPs was performed using TaqMan assays and SimpleProbe assays. RESULTS: The SNP rs619152 had to be excluded because of assay failure. No significant differences were found in allele distribution between cases and controls for all analyzed SNPs. Therefore, we found no association with cervical dystonia for the analyzed SNPs in our Spanish population. CONCLUSIONS: We did not find any evidence supporting the association of NALCN with cervical dystonia, indicating that this gene is not implicated in the pathogenesis of this disorder in our cervical dystonia population.

RESUMEN

BACKGROUND: A polymorphism in brain-derived neurotrophic factor (BDNF) (Val66Met) has been reported as a risk factor in primary dystonia. However, overall the results have been inconclusive. Our aim was to clarify the association of Val66Met with primary dystonia, and with the most prevalent clinical subtypes, cervical dystonia and blepharospasm. METHODS: We conducted a Spanish multicenter case-control study (including 680 primary dystonia patients and 788 healthy controls) and performed a meta-analysis integrating our study and six previously published studies (including a total of 1,936 primary dystonia patients and 2,519 healthy controls). RESULTS: We found no allelic or genotypic association with primary dystonia, cervical dystonia, or blepharospasm risks, for the allele A (Met) from a BDNF Val66Met polymorphism in our case-control study. This was confirmed by results from our meta-analysis in white and mixed ethnic populations in any genetic model. CONCLUSION: We did not find any evidence supporting the association of the BDNF Val66Met polymorphism with primary dystonia.

RESUMEN

Recent works in the field of Social Psychology have shown the importance of studying subjective social mobility from different perspectives. In the literature about subjective societal mobility, most of the research is focused on the mobility-immobility framing. However, several authors suggested studying social mobility beliefs effects differentiating according to mobility's trajectory, that is, upward (i.e., improving status over time) and downward (i.e., getting worse in status over time). The present research was motivated by the lack of measures that discriminate between beliefs in upward and downward societal mobility. Across two studies using different samples of the Spanish adult population, we examined both dimensions of social mobility beliefs and tested their predictive validity on other related constructs. In Study 1 (N = 164), with an EFA, we corroborated the independence between the two types of mobility. The internal structure was confirmed by a CFA in Study 2 (N = 400). Furthermore, it was shown that upward and downward mobility beliefs are differently related to other related constructs. The results from Studies 1-2 showed good convergent validity. In all correlations with the different constructs (attitudes towards inequality, meritocratic beliefs, justification of the economic system, and status anxiety) we found opposite direction effects for both types of societal mobility (upward and downward). The development of this new instrument can help to deepen our understanding of the psychosocial consequences of subjective social mobility, as well as to differentiate two processes that may have different consequences.

RESUMEN

Poverty is a phenomenon that affects men and women differently. In the current research, we examined social perceptions of poor men and women across three experiments focusing on attributions for poverty, classist attitudes, and stereotypes about poor people. In Study 1, participants from the general population (N = 484) made more individualistic (dispositional) attributions for men's poverty compared to women's poverty, blaming men more for their poverty. Participants also believed that men would manage the assistance they received from the state more poorly than women. These patterns were observed across all three studies. In Study 2 (N = 256), we also found that more individualistic attributions for why men were in poverty predicted more negative attitudes toward social protection policies concerning men. In Study 3 (N = 358), we replicated the results observed in Study 2, and found that women in poverty were described as mor communal and competent than men in poverty. We interpret these results considering the operation of traditional gender roles as well as the parallelism between stereotypes of women and poor people. Our results are relevant to the framing of the proposals by social organizations, political parties, and emancipation movements that advocate for policies and programs to address poverty.

RESUMEN

Economic inequality has consequences at the social-psychological level, such as in the way people make inferences about their environment and other people. In the present two preregistered studies, we used a paradigm of an organizational setting to manipulate economic inequality and measured ascriptions of agentic versus communal traits to employees and the self. In Study 1 (N = 187), participants attributed more agency than communion to a middle-status employee, and more communion than agency when economic equality was salient. In Study 2 (N = 198) this finding was replicated. Further, this inequality-agency association was explained by perceptions of competitive employee relationships. Results, moreover, suggested that participants mainly attributed more communion than agency to themselves in the equality condition. We conclude that agency and communion ascriptions may be functional and thus inform about the expectations people have on the nature of social relationships in the face of economic inequality.

RESUMEN

The study of coordination practices in health policy is a central aspect. The need for further research has been recently highlighted because of COVID-19. In this sense, dialogic practices (DP) have been identified but not validated yet. The purpose of this study is to develop and validate a DP questionnaire for healthcare teams. Items were identified based on a literature review, and the content validation was carried out by means of a Delphi study. A total of 10 experts assessed the clarity and appropriateness of the items and their corresponding measurement scales. After two rounds, a high level of consensus was reached, with agreement of 90% or higher on all items, and a high degree of stability and concordance in the results. This study resulted in a questionnaire consisting of four items, one for each identified DP initially proposed to the experts, as no other practices were revealed. From a practical perspective, the validation of these items constitutes a methodological innovation that responds to the call in the literature to open new avenues for comparative studies, and the possibility of generalising the findings and bringing together different approaches to the problem of coordination, which is key in health policy where unforeseen situations emerge.

RESUMEN

Carbon fiber reinforced polymers (CFRPs) are interesting materials due to their excellent properties, such as their high strength-to-weight ratio, low thermal expansion, and high fatigue resistance. However, to meet the requirements for their assembly, the drilling processes involved should be optimized. Defects such as delamination, dimensional errors and poor internal surface finish can lead to the premature failure of parts when bolt-joined or rivet-connected. In addition, the characteristic anisotropy and heterogeneity of these materials, and the issues related to the temperature reached during drilling, make it difficult to obtain optimal cutting parameters or to achieve high material removal rates. This research focuses on the optimization of the CFRPs drilling process by means of experimental analysis-varying the feed and spindle speed-for two different types of commercial drills-a twist tool and a dagger tool. An automatic image processing methodology was developed for the evaluation of the dimensional accuracy and delamination of the holes. The optimization was carried out using a multi-objective regression technique based on the dimensional deviations, delamination and surface finish. The areas with favorable machining conditions have been delimited for both tools and the results indicate that the twist tool allows one to achieve more productive cutting conditions than the dagger tool, when the combination of low feeds and high spindle speeds are the conditions to be avoided.

RESUMEN

BACKGROUND: Pilot clinical trials have shown the safety of intra-arterial bone marrow mononuclear cells (BMMNCs) in stroke. However, the efficacy of different doses of intra-arterial BMMNCs in patients with acute stroke has not been tested in a randomised clinical trial. We aimed to show safety and efficacy of two different doses of autologous intra-arterial BMMNC transplantation in patients with acute stroke. METHODS: The IBIS trial was a multicentre phase 2, randomised, controlled, investigator-initiated, assessor-blinded, clinical trial, in four stroke centres in Spain. We included patients (aged 18-80 years) with a non-lacunar, middle cerebral artery ischaemic stroke within 1-7 days from stroke onset and with a National Institutes of Health Stroke Scale score of 6-20. We randomly assigned patients (2:1:1) with a computer-generated randomisation sequence to standard of care (control group) or intra-arterial injection of autologous BMMNCs at one of two different doses (2 × 106 BMMNCs/kg or 5 × 106 BMMNCs/kg). The primary efficacy outcome was the proportion of patients with modified Rankin Scale scores of 0-2 at 180 days in the intention-to-treat population, comparing each BMMNC dose group and the pooled BMMNC group versus the control group. The primary safety endpoint was the proportion of serious adverse events. This trial was registered at ClinicalTrials.gov, NCT02178657 and is completed. FINDINGS: Between April 1, 2015, and May 20, 2021, we assessed 114 patients for eligibility. We randomly assigned 77 (68%) patients: 38 (49%) to the control group, 20 (26%) to the low-dose BMMNC group, and 19 (25%) the high-dose BMMNC group. The mean age of participants was 62·4 years (SD 12·7), 46 (60%) were men, 31 (40%) were women, all were White, and 63 (82%) received thrombectomy. The median NIHSS score before randomisation was 12 (IQR 9-15), with intra-arterial BMMNC injection done a median of 6 days (4-7) after stroke onset. The primary efficacy outcome occurred in 14 (39%) patients in the control group versus ten (50%) in the low-dose group (adjusted odds ratio 2·08 [95% CI 0·55-7·85]; p=0·28), eight (44%) in the high-dose group (1·89 [0·52-6·96]; p=0·33), and 18 (47%) in the pooled BMMNC group (2·22 [0·72-6·85]; p=0·16). We found no differences in the proportion of patients who had adverse events or dose-related events, but two patients had a groin haematoma after cell injection in the low-dose BMMNC group. INTERPRETATION: Intra-arterial BMMNCs were safe in patients with acute ischaemic stroke, but we found no significant improvement at 180 days on the mRS. Further clinical trials are warranted to investigate whether improvements might be possible at different timepoints. FUNDING: Instituto de Salud Carlos III co-funded by the European Regional Development Fund/European Social Fund, Mutua Madrileña, and the Regional Ministry of Health of Andalusia.

RESUMEN

The present research deals with two forms of dehumanization: 1) denying uniquely human attributes to others (seeing them as animals); 2) denying human nature to others (seeing them as machines or automata). Studies 1 and 2 explored these two forms of dehumanization, analyzing whether people associated their ingroup more with human-related words (vs. animal- vs. machine-related words) than two different outgroups. A paper and pencil procedure was used to find out which words were associated with the surnames of the ingroup (Spaniards) or the outgroup (Germans, Gypsies). Results showed that participants were more ready to link ingroup than outgroup surnames to human words. They also linked more Gypsy surnames to animal-related words and German surnames with machine-related words. Studies 3 and 4 used the Implicit Association Test to analyze the same ideas and replicated the results of Studies 1 and 2.

RESUMEN

This study involved 219 women participants. The main aim of the present study is to examine the perceived consequences of a work-related promotion for the female partner in a heterosexual relationship. The impact of the promotion was manipulated - both partners share paid and domestic work, the male partner taking responsibility for all the domestic work - or female partner continuing to do all the domestic work, as well as the male partner's sexist ideology. Finally, the study examined gender ideology of participants. The results showed that participants felt that violence was more likely when the male partner was presented as sexist and that this was due to a perception of threat on the part of the male partner.

RESUMEN

Economic inequality shapes the degree to which people and different social groups are perceived in stereotypical ways. Our research sought to investigate the impact of the perception of economic inequality in an organizational setting on expectations of social diversity in the organization's workforce, across the dimensions of gender and ethnicity. Combining data from previous experiments, we first explored in one set of studies (Studies 1a and 1b; N = 378) whether the degree of economic inequality in a fictitious organization affected participants' expectations of the representation of minority vs. majority group employees. We found that when we presented an organization with unequal (vs. equal) distribution of economic wealth amongst its employees to study participants, they expected the presence of men and White majority individuals to be larger than the presence of women and ethnic minorities. Second, we tested our hypotheses and replicated these initial effects in a pre-registered study (Study 2: N = 449). Moreover, we explored the potential mediating role of perceived diversity climate, that is, the perception that the organization promotes and deals well with demographic diversity. Findings revealed that an organizational setting that distributed resources unequally (vs. equally) was associated with a more adverse diversity climate, which, in turn, correlated with expectations of a lower presence of minority group employees in the organization. We concluded that economic inequality creates a context that modulates perceptions of a climate of social exclusion which likely affects the possibilities for members of disadvantaged groups to participate and develop in organizations.

RESUMEN

In this paper, we analyze the influence of the perceived level of economic inequality in daily life on people's recognition of the perceived humanity gap between low- and high-socioeconomic groups within society. To achieve this purpose, in Studies 1A-B, we analyzed the relationship between economic inequality and the humanity gap. In Studies 2A-B, we manipulated the level of inequality (low vs. high) to identify differences in the humanity gap. Results indicated that higher perceptions of economic inequality lead individuals to recognize a wider humanity gap between low- and high-socioeconomic groups in society. Implications are discussed.

RESUMEN

Membership in voluntary organizations is associated with individual and social benefits. Due to the negative consequences of the global pandemic on older people, and the governmental challenges posed by population aging, voluntary membership is of great importance to society. To effectively promote volunteering among older people, it is necessary to understand the determinants of voluntary membership. This study analyses the influence of individual values-secular/traditional and survival/self-expression-on voluntary membership among European adults (N = 31,985). Specifically, it examines which values orient two age groups (middle age: 50-64 and old age: 65-79), as well as men and women toward a certain type of association (Social Awareness; Professional and Political; Education and Leisure; Religion). The sample of 31,985 comprises 60% of adults aged 50-64 and 40% aged 65-79; of which 56% are women and 44% men. The empirical estimation considers different levels of data aggregation: individual, national and welfare system, therefore multilevel analysis is used as an analytical strategy. Individual-level variables from the Integrated Values Survey (2005/09, 2010/14, and 2017/20) and national-level variables (Gini Index and Gross Domestic Product Per Capita) from the World Bank and Eurostat are used. The results indicate that traditional and self-expression values promote membership in voluntary organizations in general more than secular and survival values. However, there are differences according to the type of organization. Furthermore, values are found to moderate the effect of age and gender on voluntary membership.
