    Aim: To present a protocol study directed at tackling gender discrimination against Roma girls by empowering their mattering so they can envision their own futures and choose motherhood only if—and when—they are ready. Background: Motherhood among Roma girls (RGM) in Europe impoverishes their lives, puts them at risk of poor physical and mental health and precipitates school dropouts. Overwhelming evidence affirms that the conditions of poverty and the social exclusionary processes they suffer have a very important explanatory weight in their sexual and reproductive decisions. Methods: Through a Community-based Participatory Action Research design, 20–25 Roma girls will be recruited in each one of the four impoverished communities in Bulgaria, Romania and Spain. Data collection and analysis: Desk review about scientific evidences and policies will be carried out to frame the problem. Narratives of Roma women as well as baseline and end line interviews of girl participants will be collected through both qualitative and quantitative techniques. Quantitative data will be gathered through reliable scales of mattering, socio–political agency, satisfaction with life and self. A narrative analysis of the qualitative information generated in the interviews will be carried out. Expected results: (1) uncover contextual and psychosocial patterns of girl-motherhood among Roma women; (2) build critical thinking among Roma girls to actively participate in all decisions affecting them and advocate for their own gender rights within their communities; and (3) empower Roma girls and their significant adults to critically evaluate their own initiatives and provide feedback to their relevant stakeholders. Conclusions: Roma girls will improve their educational aspirations and achievements and their social status while respecting and enhancing Roma values.This initiative is funded by the DG Justice of the European Commission in the Call for proposals for action grants under 2017 Rights Equality and Citizenship Work REC-AG #809813

    © The Author(s) 2015. Published by Oxford University Press. Organelle genomes evolve rapidly as compared with nuclear genomes and have been widely used for developing microsatellites or simple sequence repeats (SSRs) markers for delineating phylogenomics. In our previous reports, we have established the largest repository of organelle SSRs, ChloroMitoSSRDB, which provides access to 2161 organelle genomes (1982 mitochondrial and 179 chloroplast genomes) with a total of 5838 perfect chloroplast SSRs, 37 297 imperfect chloroplast SSRs, 5898 perfect mitochondrial SSRs and 50 355 imperfect mitochondrial SSRs across organelle genomes. In the present research, we have updated ChloroMitoSSRDB by systematically analyzing and adding additional 191 chloroplast and 2102 mitochondrial genomes. With the recent update, ChloroMitoSSRDB 2.00 provides access to a total of 4454 organelle genomes displaying a total of 40 653 IMEx Perfect SSRs (11 802 Chloroplast Perfect SSRs and 28 851 Mitochondria Perfect SSRs), 275 981 IMEx Imperfect SSRs (78 972 Chloroplast Imperfect SSRs and 197 009 Mitochondria Imperfect SSRs), 35 250 MISA (MIcroSAtellite identification tool) Perfect SSRs and 3211 MISA Compound SSRs and associated information such as location of the repeats (coding and non-coding), size of repeat, motif and length polymorphism, and primer pairs. Additionally, we have integrated and made available several in silico SSRs mining tools through a unified web-portal for in silico repeat mining for assembled organelle genomes and from next generation sequencing reads. ChloroMitoSSRDB 2.00 allows the end user to perform multiple SSRs searches and easy browsing through the SSRs using two repeat algorithms and provide primer pair information for identified SSRs for evolutionary genomics

    In this study, we evaluated the metabolic profile of the aerobic microorganism of Endomyces magnusii with a complete respiration chain and well-developed mitochondria system during long-lasting cultivation. The yeast was grown in batches using glycerol and glucose as the sole carbon source for a week. The profile included the cellular biological and chemical parameters, which determined the redox status of the yeast cells. We studied the activities of the antioxidant systems (catalases and superoxide dismutases), glutathione system enzymes (glutathione peroxidase and reductase), aconitase, as well as the main enzymes maintaining NADPH levels in the cells (glucose-6-phosphate dehydrogenase and NADP+-isocitrate dehydrogenase) during aging of Endomyces magnusii on two kinds of substrates. We also investigated the dynamics of change in oxidized and reduced glutathione, conjugated dienes, and reactive oxidative species in the cells at different growth stages, including the deep stationary stages. Our results revealed a similar trend in the changes in the activity of all the enzymes tested, which increased 2–4-fold upon aging. The yeast cytosol had a very high reduced glutathione content, 22 times than that of Saccharomyces cerevisiae, and remained unchanged during growth, whereas there was a 7.5-fold increase in the reduced glutathione-to-oxidized glutathione ratio. The much higher level of reactive oxidative species was observed in the cells in the late and deep stationary phases, especially in the cells using glycerol. Cell aging of the culture grown on glycerol, which promotes active oxidative phosphorylation in the mitochondria, facilitated the functioning of powerful antioxidant systems (catalases, superoxide dismutases, and glutathione system enzymes) induced by reactive oxidative species. Moreover, it stimulated NADPH synthesis, regulating the cytosolic reduced glutathione level, which in turn determines the redox potential of the yeast cell during the early aging process

The potential contribution of innate immune cells, such as natural killer (NK) cells and dendritic cells (DC), to the pSS pathology remains understudied. Here, we identified an enriched CD16+ CD56hi NK cell subset associated with higher cytotoxic function, as well as elevated proportions of inflammatory CD64+ conventional dendritic cell (cDC2) subtype that expresses increased levels of MICa/b, the ligand for the activating receptor NKG2D, in pSS individuals. Circulating cDC2 from pSS patients efficiently induced activation of cytotoxic NK cells ex vivo and were found in proximity to CD56+ NK cells in salivary glands (SG) from pSS patients. Interestingly, transcriptional activation of IFN signatures associated with the RIG-I/DDX60 pathway, IFN I receptor, and its target genes regulate the expression of NKG2D ligands on cDC2 from pSS patients. Finally, increased proportions of CD64hi RAE-1+ cDC2 and NKG2D+CD11b+CD27+ NK cells were present in vivo in the SG after poly I:C injection. Our study provides novel insight into the contribution and interplay of NK and cDC2 in pSS pathology and identifies new potential therapy targetsRTI2018-097485-A-I00, PID2021-127899OB-I0

    The purpose of this study was to conduct a literature review of cost-benefit studies on pharmacotherapy and psychotherapy treatments of alcohol dependence (AD). A literature search was performed in multiple electronic bibliographic databases. The search identified seven psychotherapy studies from the USA and two pharmacotherapy studies from Europe. In the psychotherapy studies, major benefits are typically seen within the first six months of treatment. The benefit-cost ratio ranged from 1.89 to 39.0. Treatment with acamprosate was found to accrue a net benefit of 21,301 BEF (528 €) per patient over a 24-month period in Belgium and lifetime benefit for each patient in Spain was estimated to be Pta. 3,914,680 (23,528 €). To date, only a few studies exist that have examined the cost-benefit of psychotherapy or pharmacotherapy treatment of AD. Most of the available treatment options for AD appear to produce marked economic benefits

    The individual contribution of specific myeloid subsets such as CD1c+ conventional dendritic cells (cDC) to perpetuation of Rheumatoid Arthritis (RA) pathology remains unclear. In addition, the specific innate sensors driving pathogenic activation of CD1c+ cDCs in RA patients and their functional implications have not been characterized. Here, we assessed phenotypical, transcriptional and functional characteristics of CD1c+ and CD141+ cDCs and monocytes from the blood and synovial fluid of RA patients. Increased levels of CCR2 and the IgG receptor CD64 on circulating CD1c+ cDC associated with the presence of this DC subset in the synovial membrane in RA patients. Moreover, synovial CD1c+ cDCs are characterized by increased expression of proinflammatory cytokines and high abilities to induce pathogenic IFNγ+IL-17+ CD4+ T cells in vitro. Finally, we identified the crosstalk between Fcγ Receptors and NLRC4 as a new potential molecular mechanism mediating pathogenic activation, CD64 upregulation and functional specialization of CD1c+ cDCs in response to dsDNA-IgG in RA patients.E.M.G. was supported by Comunidad de Madrid Talento Program (2017-T1/BMD5396), Ramón y Cajal Program (RYC2018-024374-I), the MINECO RETOS program (RTI2018-097485-A-I00), La Caixa Foundation (HR20-00218), CIBERINF (CB21/13/00107) and the TV3 Marató (REDINCOV).

    Pion and proton showers in the CALICE scintillator-steel analogue hadron calorimeter

    Full text link
    Showers produced by positive hadrons in the highly granular CALICE scintillator-steel analogue hadron calorimeter were studied. The experimental data were collected at CERN and FNAL for single particles with initial momenta from 10 to 80 GeV/c. The calorimeter response and resolution and spatial characteristics of shower development for proton- and pion-induced showers for test beam data and simulations using Geant4 version 9.6 are compared.Comment: 26 pages, 16 figures, JINST style, changes in the author list, typos corrected, new section added, figures regrouped.

    Shower development of particles with momenta from 15 GeV to 150 GeV in the CALICE scintillator-tungsten hadronic calorimeter

    Full text link
    We present a study of showers initiated by electrons, pions, kaons, and protons with momenta from 15 GeV to 150 GeV in the highly granular CALICE scintillator-tungsten analogue hadronic calorimeter. The data were recorded at the CERN Super Proton Synchrotron in 2011. The analysis includes measurements of the calorimeter response to each particle type as well as measurements of the energy resolution and studies of the longitudinal and radial shower development for selected particles. The results are compared to Geant4 simulations (version 9.6.p02). In the study of the energy resolution we include previously published data with beam momenta from 1 GeV to 10 GeV recorded at the CERN Proton Synchrotron in 2010.Comment: 35 pages, 21 figures, 8 table

    Hadron shower decomposition in the highly granular CALICE analogue hadron calorimeter

    Get PDF
    The spatial development of hadronic showers in the CALICE scintillator-steel analogue hadron calorimeter is studied using test beam data collected at CERN and FNAL for single positive pions and protons with initial momenta in the range from 10 to 80 GeV/c. Both longitudinal and radial development of hadron showers are parametrised with two-component functions. The parametrisation is fit to test beam data and simulations using the QGSP_BERT and FTFP_BERT physics lists from Geant4 version 9.6. The parameters extracted from data and simulated samples are compared for the two types of hadrons. The response to pions and the ratio of the non-electromagnetic to the electromagnetic calorimeter response, h/e, are estimated using the extrapolation and decomposition of the longitudinal profiles.Comment: 38 pages, 19 figures, 5 tables; author list changed; submitted to JINS
