El Retorno de los Migrantes Paraguayos: Una Oportunidad para el Desarrollo Local y Nacional
Debido a la crisis mundial que están atravesando los distintos países europeos, especialmente España, país que concentra la mayor cantidad de paraguayos, después de Argentina, se consideró oportuno estudiar el efecto contrario de la migración que se da actualmente a nivel nacional, es decir, el retorno de migrantes. Se anexa al libro principal, un documento de resumen del mismo.CONACYT – Consejo Nacional de Ciencia y TecnologíaPROCIENCI
Environmental education and young: The influence of the belief and attitudes toward pro-environmental behavior in ninth grade students, of Central Department (2015)- Paraguay
The objective of this study was to analyze the influence of belief and attitudes the ninth grade students toward pro-environmental behaviors. The data were collected from non-probabilistic sample from public school of the Central Department from Paraguay. We apply a Likert questionnaire to 200 students from ninth grade, sort out items such as beliefs, attitudes and behaviors. The methodology applied was the chi-square test where we want to relate the beliefs to attitudes and sustainable behaviors. The results suggest that general beliefs about the importance of environment they do not have implicance in attitudes and behaviors environmental, however, when the beliefs are specific, and clearly wrong, the consequences in the actions are not in lines with the sustainability of the environment are clear. Hence, is very
important to rethink about Paraguay environmental education and arise actions strategy that implies the involvement and coordination with different sectors of society

Síntesis de hidrotalcitas de Co, Ni y Cu y su uso en la preparación de 4-fenil-1,2,3-triazol con un fragmento carbohidrato
En este trabajo se presenta la síntesis, caracterización y evaluación catalítica de las hidrotalcitas de Co(II), Ni(II) y Cu(II) en la preparación de 4-fenil-1,2,3-triazol derivado de la 3-azida-1,2:5,6-diisopropiliden-β-D-glucofuranosa. Las hidrotaciltas empleadas en este trabajo fueron sintetizadas por el método de coprecipitación empleando una relación 3:1 de las sales de nitrato de Co, Ni o Cu con respecto al nitrato de aluminio. Dichas hidrotalcitas fueron secadas, calcinadas y caracterizadas por difracción de rayos X de polvos para posteriormente utilizarlas como catalizadores heterogéneos en la síntesis del triazol mencionado en condiciones de calentamiento por microondas. Los resultados indican que de las hidrotalcitas utilizadas, la de Cu/Al es la más eficiente para realizar esta transformación.In this work, the synthesis, characterization and catalytic evaluation of Co(II), Ni(II) and Cu(II) hydrotalcites in the preparation of 4-phenyl-1,2,3-triazole derivative of 3 -azide-1,2:5,6-diisopropylidene-β-D-glucofuranose is presented. The hydrotalcites used in this work were synthesized by the coprecipitation method using a 2:1 ratio of Co, Ni or Cu nitrate with respect to aluminum nitrate. These hydrotalcites were dried, calcined, and characterized by powder X-ray diffraction to subsequently use them as heterogeneous catalysts in the synthesis of the mentioned triazole under microwave heating conditions. The results indicate that of the hydrotalcites used, Cu/Al is the most efficient to carry out this transformation
Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2
The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality
A investigar se aprende investigando. Programa de Jóvenes Investigadores
Este trabajo recoge las historias de cambio de jóvenes investigadoras que participaron en un programa de formación desarrollado por el Instituto Desarrollo de Paraguay. Este programa es una oportunidad de aprendizaje y una respuesta a la necesidad que muchos jóvenes tienen de iniciarse en la investigación social; en la actualidad, las universidades paraguayas limitan las posibilidades de trabajar en la producción de conocimiento, ya que la enseñanza no se inclina hacia esta labor ni se propician espacios de investigación, en especial en el campo de las ciencias sociales. Para comprender el proceso vivido y la debilidad institucional y profesional de la investigación social en Paraguay, en este artículo exponemos la realidad sociohistórica y analizamos los cambios en las vidas de las participantes luego de formar parte de este programa

GWAS and meta-analysis identifies 49 genetic variants underlying critical COVID-19
Data availability: Downloadable summary data are available through the GenOMICC data site (https://genomicc.org/data). Summary statistics are available, but without the 23andMe summary statistics, except for the 10,000 most significant hits, for which full summary statistics are available. The full GWAS summary statistics for the 23andMe discovery dataset will be made available through 23andMe to qualified researchers under an agreement with 23andMe that protects the privacy of the 23andMe participants. For further information and to apply for access to the data, see the 23andMe website (https://research.23andMe.com/dataset-access/).

Despite the advanced stage of illness at presentation, we have shown that host genetics in patients who are critically ill with COVID-19 can identify immunomodulatory therapies with strong beneficial effects in this group3. Here we analyse 24,202 cases of COVID-19 with critical illness comprising a combination of microarray genotype and whole-genome sequencing data from cases of critical illness in the international GenOMICC (11,440 cases) study, combined with other studies recruiting hospitalized patients with a strong focus on severe and critical disease: ISARIC4C (676 cases) and the SCOURGE consortium (5,934 cases). To put these results in the context of existing work, we conduct a meta-analysis of the new GenOMICC genome-wide association study (GWAS) results with previously published data. We find 49 genome-wide significant associations, of which 16 have not been reported previously. To investigate the therapeutic implications of these findings, we infer the structural consequences of protein-coding variants, and combine our GWAS results with gene expression data using a monocyte transcriptome-wide association study (TWAS) model, as well as gene and protein expression using Mendelian randomization. We identify potentially druggable targets in multiple systems, including inflammatory signalling (JAK1), monocyte–macrophage activation and endothelial permeability (PDE4A), immunometabolism (SLC2A5 and AK5), and host factors required for viral entry and replication (TMPRSS2 and RAB2A).GenOMICC was funded by Sepsis Research (the Fiona Elizabeth Agnew Trust), the Intensive Care Society, a Wellcome Trust Senior Research Fellowship (to J.K.B., 223164/Z/21/Z), the Department of Health and Social Care (DHSC), Illumina, LifeArc, the Medical Research Council, UKRI, a BBSRC Institute Program Support Grant to the Roslin Institute (BBS/E/D/20002172, BBS/E/D/10002070 and BBS/E/D/30002275) and UKRI grants MC_PC_20004, MC_PC_19025, MC_PC_1905 and MRNO2995X/1.
