At the beginnings of the funerary Megalithism in Iberia at Campo de Hockey necropolis

The excavations undertaken at the Campo de Hockey site in 2008 led to the identification of a major Neolithic necropolis in the former Island of San Fernando (Bay of Cádiz). This work presents the results of the latest studies, which indicate that the site stands as one of the oldest megalithic necropolises in the Iberian Peninsula. The main aim of this work is to present with precision the chronology of this necropolis through a Bayesian statistical model that confirms that the necropolis was in use from c. 4300 to 3800 cal BC. The presence of prestige grave goods in the earliest and most monumental graves suggest that the Megalithism phenomenon emerged in relation to maritime routes linked to the distribution of exotic products. We also aim to examine funerary practices in these early megalithic communities, and especially their way of life and the social reproduction system. As such, in addition to the chronological information and the Bayesian statistics, we provide the results of a comprehensive interdisciplinary study, including anthropological, archaeometric and genetic data.State Research Agency (SRA)European Commission HAR2017-87324-P 2014-2020 ERDF Operational ProgrammeDepartment of Economy, Knowledge, Business and University of the Regional Government of Andalusia FEDER-UCA18-106917 CEIMAR CEIJ-015European Social Fund (ESF) D1113102E3Junta de Andaluci

Estrategias de resolución en un problema sobre probabilidad condicional en la XXIX Olimpiada aragonesa

En el currículo estatal y autonómico aragonés la probabilidad condicional aparece explícitamente en 4.º de ESO. Queda fuera de toda duda que se trata de una de las nociones básicas de probabilidad que todo estudiante de secundaria debería comprender, bien por su importancia e interés en la estocástica, como por los potentes razonamientos informales que se sustentan alrededor de ella (Borovcnick, 2012). Sin embargo, junto con la idea de independencia de sucesos, los problemas asociados a la probabilidad condicional constituyen una fuente habitual para la expresión de sesgos de razonamiento y de dificultades para el alumnado (Batanero, 2014). Por otro lado, como varios elementos sobre los que se construye la idea de probabilidad condicional aparecen desde el comienzo de la secundaria (por ejemplo, tablas o diagramas de árbol), una pregunta que nos podemos plantear es si el alumnado es capaz de desarrollar estrategias intuitivas en situaciones donde aparecen sucesos condicionados. Si esto fuera así, estas estrategias podrían servir de base para el diseño de secuencias didácticas (Martínez-Juste y otros, 2015)..

Quo Vadis Clozapine? A Bibliometric Study of 45 Years of Research in International Context

We have carried out a bibliometric study about the international scientific publications on clozapine. We have used the EMBASE and MEDLINE databases, and we applied bibliometric indicators of production, as Price’s Law on the increase of scientific literature. We also calculated the participation index (PI) of the different countries. The bibliometric data have also been correlated with some social and health data from the 12 most productive countries in biomedicine and health sciences. In addition, 5607 original documents dealing with clozapine, published between 1970 and 2013, were downloaded. Our results state non-fulfilment of Price’s Law, with scientific production on clozapine showing linear growth (r = 0.8691, vs. r = 0.8478 after exponential adjustment). Seven of the 12 journals with the highest numbers of publications on clozapine have an Impact Factor > 2. Among the countries generating clozapine research, the most prominent is the USA (PI = 24.32), followed by the UK (PI = 6.27) and Germany (PI = 5.40). The differences among countries on clozapine research are significantly related to economic variables linked to research. The scientific interest in clozapine remains remarkable, although after the application of bibliometric indicators of production, a saturation point is evident in the growth of scientific literature on this topic

Directed Surfaces in Disordered Media

The critical exponents for a class of one-dimensional models of interface depinning in disordered media can be calculated through a mapping onto directed percolation (DP). In higher dimensions these models give rise to directed surfaces, which do not belong to the directed percolation universality class. We formulate a scaling theory of directed surfaces, and calculate critical exponents numerically, using a cellular automaton that locates the directed surfaces without making reference to the dynamics of the underlying interface growth models.Comment: 4 pages, REVTEX, 2 Postscript figures avaliable from [email protected]

Maternal and neonatal immune response to SARS-CoV-2, IgG transplacental transfer and cytokine profile

SARS-CoV-2 infected pregnant women are at increased risk of severe COVID-19 than non-pregnant women and have a higher risk of adverse pregnancy outcomes like intrauterine/fetal distress and preterm birth. However, little is known about the impact of SARS-CoV-2 infection on maternal and neonatal immunological profiles. In this study, we investigated the inflammatory and humoral responses to SARS-CoV-2 in maternal and cord blood paired samples. Thirty-six pregnant women were recruited at delivery at Hospital Sant Joan de Déu, Barcelona, Spain, between April-August 2020, before having COVID-19 available vaccines. Maternal and pregnancy variables, as well as perinatal outcomes, were recorded in questionnaires. Nasopharyngeal swabs and maternal and cord blood samples were collected for SARS-CoV-2 detection by rRT-PCR and serology, respectively. We measured IgM, IgG and IgA levels to 6 SARS-CoV-2 antigens (spike [S], S1, S2, receptor-binding domain [RBD], nucleocapsid [N] full-length and C-terminus), IgG to N from 4 human coronaviruses (OC43, HKU1, 229E and NL63), and the concentrations of 30 cytokines, chemokines and growth factors by Luminex. Mothers were classified as infected or non-infected based on the rRT-PCR and serology results. Sixty-four % of pregnant women were infected with SARS-CoV-2 (positive by rRT-PCR during the third trimester and/or serology just after delivery). None of the newborns tested positive for rRT-PCR. SARS-CoV-2 infected mothers had increased levels of virus-specific antibodies and several cytokines. Those with symptoms had higher cytokine levels. IFN-? was increased in cord blood from infected mothers, and in cord blood of symptomatic mothers, EGF, FGF, IL-17 and IL-15 were increased, whereas RANTES was decreased. Maternal IgG and cytokine levels showed positive correlations with their counterparts in cord blood. rRT-PCR positive mothers showed lower transfer of SARS-CoV-2-specific IgGs, with a stronger effect when infection was closer to delivery. SARS-CoV-2 infected mothers carrying a male fetus had higher antibody levels and higher EGF, IL-15 and IL-7 concentrations. Our results show that SARS-CoV-2 infection during the third trimester of pregnancy induces a robust antibody and cytokine response at delivery and causes a significant reduction of the SARS-CoV-2-specific IgGs transplacental transfer, with a stronger negative effect when the infection is closer to delivery.Copyright © 2022 Rubio, Aguilar, Bustamante, Muñoz, Vázquez-Santiago, Santano, Vidal, Melero, Parras, Serra, Santamaria, Carolis, Izquierdo, Gómez-Roig, Dobaño, Moncunill and Mazarico

Guía sobre las enfermedades fúngicas de la madera de la vid

Reunión Grupo de Trabajo de experimentación en viticultura y enología. 34ª Reunión: Centro de Transferencia Agroalimentaria: Gobierno de Aragón: Zaragoza: 10 y 11 de abril de 2019. ANEXOLas enfermedades fúngicas de la madera de la vid (EMV) son uno de los retos más importantes que actualmente debe afrontar la viticultura en todo el mundo para su sostenibilidad. Estas enfermedades causan daños severos en el viñedo todos los años y su incidencia está creciendo rápidamente en todos los países productores (De la Fuente et al., 2016). Las EMV están causadas por varios hongos patógenos que viven y colonizan la madera de los órganos perennes, causando necrosis y decoloración de la madera, infecciones vasculares, y descomposición esponjosa seca. Las viñas afectadas muestran, externamente, un decaimiento general y progresivo (retraso de la brotación, yemas muertas, decaimiento de la planta, parada del desarrollo, clorosis, apoplejía, etc.), generalmente asociado a unos síntomas foliares acordes a las diferentes enfermedades, que inicialmente pueden causar pérdida de productividad y eventualmente la muerte de las plantas (Gramaje et al., 2018). En España se estima una media del 3% de plantas afectadas por EMV, aunque existen plantaciones recién establecidas en las que su incidencia podría superar el 20%, generando pérdidas económicas anuales muy elevadas (De la Fuente et al., 2016). Según estimaciones recientes, el coste anual de replantar el 1% de vid del cultivar Tempranillo en La Rioja debido a las EMV asciende a 7,16 millones de euros anuales (Martínez-Diz et al., 2019). En Francia, se estima que aproximadamente un 12% de los viñedos son improductivos debido a las EMV, causando unas pérdidas anuales de 1 billón de euros (Lorch, 2014)

A bibliometric analysis of scientific research on atypical antipsychotic drugs in India during 1998-2013

Background: We carried out a bibliometric study on the scientific publications on atypical antipsychotic drugs (AADs) from India. Methods: Using the EMBASE and MEDLINE databases, we performed the selection of documents produced in India. We applied bibliometric indicators of production and dispersion, namely Price’s law on the increase of scientific literature and Bradford’s law, respectively. We also calculated the participation index (PI) of different countries. The bibliometric data have also been correlated with relevant social and health data from India (including total per capita expenditure on health and gross domestic expenditure on research and development). Results: In this study, we identified 639 original documents published between 1998 and 2013 from India. Our results indicated fulfilment of Price’s law (correlation coefficient r = 0.9619 after exponential adjustment vs. r = 0.9382 after linear adjustment). The most widely studied AADs were olanzapine (173 documents), clozapine (117), risperidone (100) and quetiapine (65). Publications appeared in 221 different journals, with only 4 of the top 10 journals having an impact factor greater than 2. Division into Bradford zones yielded a nucleus occupied by the Indian Journal of Psychiatry (53 articles). It is remarkable that the 27.38% of the production is devoted to “medical/pharmaceutical chemistry” field. India has the largest ratio PI AAD / PI Psychiatry and Neurology in the world’s 12 most productive countries in biomedicine and health sciences. Conclusions: The publications on AADs in India have undergone exponential growth over the studied period, without evidence of reaching a saturation point
