Host response to respiratory syncytial virus infection

Purpose of review: Respiratory syncytial virus (RSV) infection is the leading cause of bronchiolitis and hospitalization in young infants and causes 100 000–200 000 deaths annually. There is still no licensed vaccine against RSV infection and the therapeutic options are mainly supportive. Despite almost six decades of research, important knowledge gaps remain with respect to the characterization of immune mechanisms responsible for protection and pathogenesis, as well as to the identification of risk factors that predict the severity of infection. Recent findings: Observations made in mouse models and young children suggest that the early innate immune response plays a major role in the pathogenesis of bronchiolitis due to RSV infection. Recent studies have improved our understanding of the role of the adaptive immune response mediated by TH1, TH2, TH17, regulatory T cells, and CD8þ T cells in the pathogenesis and resolution of RSV infection. Moreover, investigations performed in the last years have made important contributions to our knowledge of the immune response in young children, the principal risk group for severe disease. Summary: A comprehensive understanding of how the protective and deleterious immune response during the course of RSV infection is induced in young children remains a challenge over the coming years.Fil: Arruvito, Maria Lourdes.

Estructura espacial de eucinostomus argenteus (pisces: gerreidae) en la zona norte del caribe colombiano

Esta investigación se llevó a cabo para determinar la distribución espacial de la densidad (captura por unidad de área) – CPUA y de la estructura de tallas de Eucinostomus argenteus y su relación con las variables ambientales en la zona norte del Caribe colombiano. Los datos fueron se tomaron durante un crucero de investigación realizado en  la época seca (febrero de 2006) entre  Puerto Estrella (La Guajira) y Santa Marta (Magdalena). Las muestras biológicas se colectaron con una red de arrastre (en estratos de profundidad and lt; 50 m y 50-100 m) siguiendo un diseño de muestreo sistemático. Los individuos maduros y de tallas mayores se encontraron distribuidos principalmente entre Manaure y Punta Gallinas, donde la plataforma continental es muy ancha y la oceanografía local esta modulada por la surgencia estacional. Los peces juveniles, se distribuyeron al sur del área de estudio, entre Boca Camarones y el Río Buritaca, cerca de la costa. En este sector la plataforma es muy estrecha y con alta productividad biológica por la presencia de ríos, manglares y pastos marinos, sirviendo como zona de alimentación y refugio para E. argenteus. En general los resultados sugieren que las variables ambientales son importantes para la distribución espacial de la abundancia y las tallas de  E. argenteus en la zona norte del Caribe colombiano, siendo la temperatura y la profundidad las variables que predijeron mejor la distribución espacial de la especie

Chemiluminescence determination of antioxidant property of Zizyphus mistol and Prosopis alba during oxidative stress generated in blood by Hemolytic Uremic Syndrome-producing Escherichia coli

This study was undertaken to elucidate the antioxidant effect of Zizyphus mistol and Prosopis alba, with the hypothesis that these fruits can counteract the induction of reactive oxygen species (ROS) caused by toxins produced by Escherichia coli. In the search of nutrients effective against the Hemolytic Uremic Syndrome (HUS), we detected by chemiluminescence a protective role of both plants, due to their natural antioxidants significantly decreasing the levels of ROS induced by toxins from E. coli in blood. The ferric reducing antioxidant power (FRAP) was found to be higher in Z. mistol than in P. alba. The chemical analyses of the phenols and flavonoids present in the fruit extracts indicated that the FRAP correlated with the amount of phenolic compounds, but not with the flavonoids analyzed. Both fruits studied reduce the induction of ROS, and in this way help to prevent the development of complications related to oxidative stress generated in the blood of patients with HUS.

Measuring occupational mismatch: overeducation and overskill in Europe. Evidence from PIAAC

Occupational mismatch has been a hot topic in the economics literature in the last decades, but still today there is no consensus on how to conceptualize and measure this phenomenon. We explore the unique opportunity offered by the recent PIAAC survey to measure occupational mismatch at individual level based on both education variables (overeducation) and on skills proficiency variables (overskilling), using both objective and subjective methods for each. We use data for 17 European countries and compute a total of 20 indicators of occupation mismatch. We find that indeed the conceptualization and measurement of this phenomenon play an important role and that education and skill mismatch do not measure the same phenomenon. In fact, only a low percentage of population is both education and skill mismatched, while the majority is mismatched in only one of these types. At country level, we find a negative correlation between the incidence of education and skill mismatch, which has important policy implications when it comes to address this labour market inefficiency.JRC.DDG1.01-Econometrics and applied statistic

S-nitrosylation of NF-kB p65 inhibits TSH-induced Na+/I- symporter expression

Nitric oxide (NO) is a ubiquitous signaling molecule involved in a wide variety of cellular physiological processes. In thyroid cells, NO-synthase III-endogenously produced NO reduces thyrotropin (TSH)-stimulated thyroid specific gene expression, suggesting a potential autocrine role of NO in modulating thyroid function. Further studies indicate that NO induces thyroid dedifferentiation, as NO donors repress TSH-stimulated I- uptake. Here, we investigated the molecular mechanism underlying the NO inhibited Na+/I- Symporter (NIS)-mediated I- uptake in thyroid cells. We showed that NO donors reduce I- uptake in a concentration-dependent manner, which correlates with decreased NIS protein expression. NO-reduced I- uptake results from transcriptional repression of NIS gene rather than post-translational modifications reducing functional NIS expression at the plasma membrane. We observed that NO donors repress TSH-induced NIS gene expression by reducing the transcriptional activity of the NF-κB subunit p65. NO-promoted p65 S-nitrosylation reduces p65-mediated transactivation of the NIS promoter in response to TSH stimulation. Overall, our data are consistent with the notion that NO plays a role as an inhibitory signal to counterbalance TSH-stimulated NF-κB activation, thus modulating thyroid hormone biosynthesis.Fil: Nicola, Juan Pablo.

Occupational mismatch in Europe: Understanding overeducation and overskilling for policy making

This technical report presents EU-17 evidence on the extent of different measures of overeducation and overskilling among working age population in an attempt to provide a comprehensive understanding of the relationship between education and skill mismatch within the broader definition of occupation mismatch. It further investigates how countries differ or share common patterns in terms of amount and typology of mismatch, while investigating the socio-economic determinants responsible for different types of occupational mismatch considered. Lastly, at a very exploratory level, it provides average predicted probabilities for the different types of occupational mismatch identified using CEDEFOP skill forecast by educational level and occupation for 2020. Comparing these predicted values provides a method of measuring the overall impact on occupational mismatch of differences in age, gender or education level while controlling for other observed characteristics. Special attention is systematically paid to the role of educational systems and policies in the matterJRC.DDG.01-Econometrics and applied statistic
