Poesia naturalista. Natura cantandose, celebrandose a si misma. Desdoblandose en la estrofa, siendo, a la vez, ave, canto, contemplacion y goce. Una poesia pura, sincera, libre, lejana del lastre banal de la poesia mundana. Una poesia sin alardes y llena de belleza. No por simple y directa, menos misteriosa y profunda. Es el Creador que se regocija en las creaturas, a traves del alma poetica, que realiza la sintesis magnifica. Bosque, arcoiris, margarita, arana –Asi luz y lumbre/ gota y lluvia/ trueno y tempestad–, se presentan como signos y significado, simbolo y representacion de la Naturaleza divina

Genotoxicological studies are emerging as fundamental for knowing the hazards to our genome, to our health. Drosophila melanogaster is one of the preferable organisms for toxicological research considering its metabolic similarities (viz. on dietary input, xenobiotic metabolizing system, antioxidant enzymes and DNA repair systems) to mammals. Accordingly, somatic mutation and recombination tests (SMARTs) of D. melanogaster are fast and low-cost in vivo assays that have shown solid results evaluating genotoxicity. The w/w + SMART uses the white (w) gene as a recessive marker to monitor the presence of mutant ommatidia (eye units), indicating the occurrence of point mutations, deletions, mitotic recombination or/and nondisjunction. Additionally, several studies used SMARTs to assess antigenotoxicity, with some using the w/w + SMART. We reviewed the state of the art of the w/w + SMART used for antigenotoxicity analysis, focusing on published results, aiming to contribute to the conception of a reliable protocol in antigenotoxicity. As such, genotoxic agents with known action mechanisms, as streptonigrin (oxidative stress inducer), were used as a genotoxic insult for proving the antigenotoxic effects of natural substances (e.g. seaweeds), demonstrating the presence of antimutagens in their composition. These antigenotoxicity studies are crucial for promoting preventive measures against environmental genotoxics that affect humans daily.

Expanding conservation efforts to private land is paramount to halt biodiversity loss and achieve global conservation targets. Individual landowners can play disproportionately important roles by establishing private parks and managing them with biodiversity‐focused objectives. However, several constraints hinder the expansion of such initiatives, and little is known about their extent, characteristics and keys for success.Here, we provide insights on the conditions that favoured the establishment and conservation outcomes of a private reserve in central Spain whose management has been fully conservation‐oriented for the past two decades. We report on the actions implemented to accomplish four key targets that aimed at protecting and enhancing wildlife populations, and on the landholder's motivations to devote his personal resources to pursue this goal.The landholder suggests that public policy should reduce the bureaucratic burden to intrinsically motivated landowners and provide them technical advice, trust and financial incentives to expand conservation on private land., Ministerio de Asuntos Económicos y Transformación Digital, Ministerio de Ciencia e Innovación, Ministerio de Educación, Cultura y Deporte, Comunidad de Madrid

Three urban ministry research projects were carried out with displaced populations in Ciudad Bolívar (Bogotá, Colombia). These initiatives have allowed us to gather new insights and understanding about the imperative theological endeavour. This article intertwines theology with the symbolic world that represents the physicality of women whose bodies have become living stories and who, with the help of aesthetics, have become reading texts which opens possibilities to theological re -signification and integral salvation. Tres investigaciones en pastoral urbana con población en situación de desplazamiento forzado en Ciudad Bolívar, localidad de Bogotá, nos ha dado la pauta para adquirir nuevas comprensiones sobre el quehacer teológico. En este artículo se entrelaza la teología con el mundo simbólico que representa la corporeidad de mujeres cuyos cuerpos se convierten en relatos vivos que, con la ayuda de la estética, se transforman en textos de lectura para abrir caminos de re-significación teológica y de salvación integral.

espanolEste articulo presenta una reflexion critica sobre la historiografia dedicada al estudio de las emociones, mostrando su origen, sus logros y sus posibilidades. Para ello, el texto se organiza en tres recorridos que exploran 1) los paradigmas explicativos de lo emocional que mas han influido en los planteamientos historiograficos; 2) el interes que los afectos han suscitado en la historiografia contemporaneista desde principios del siglo XX hasta la llegada del llamado «giro afectivo»; y 3) la pluralidad de enfoques teoricos y categorias de analisis que los historiadores de las emociones han ido ofreciendo en las ultimas decadas. Teniendo todo ello en cuenta, este articulo defiende lo oportuno de poner a dialogar la historia de las emociones con diferentes categorias de analisis, como el genero o la raza, y lo ventajoso de abordar estos estudios desde otros enfoques, como la historia biografica. EnglishThis article presents a critical reflection on the historiography dedicated to the study of emotions, showing its origin, achievements and possibilities. For this, the text is organized in three sections which explore: 1) the explanatory paradigms of emotions which have influenced historiographic approaches; 2) the interest that affect has provoked in contemporary historiography from the early 20th century to the arrival of the so-called «affective turn»; and 3) the plurality of theoretical approaches and categories of analysis which historians of emotions have been offering in the last few decades. Taking the above into consideration, this article defends how appropriate it is to create a dialog between the history of emotions and different categories of analysis, such as gender or race, and how beneficial it is to address these studies from different approaches, such as biographical history. francaisCet article presente une reflexion critique sur l’historiographie dediee a l’etude des emotions, tout en retracant ses origines, ses acquis et ses possibilites.

Backgound: Traditional anthropometrics such as body mass index (BMI) or waist circumference (WC) do not fully capture the complex biology of body fat (BF) in the elderly. The Clinica Universidad de Navarra-Body Adiposity Estimator (CUN-BAE) index, based on BMI, is proposed as a better indicator of BF. However, its relation with BMI is not clear. The aim was to compare the agreement between CUN-BAE, BMI, and WC in those aged &ge, 50 years. Methods: A cross-sectional sample of 3153 Caucasian healthy adults was taken from the MCC-Spain study. The Pearson&rsquo, s correlation and its 95% confidence interval (CI), adiposity distribution, and Kappa Index (95%CI) were calculated. Results: The correlation of CUN-BAE with WC is 0.18 (95%CI 0.14&ndash, 0.21) and that with BMI is moderate (r 0.58, 95%CI 0.55&ndash, 0.60), but both increased strongly by sex. Agreement (normal weight/overweight/obesity) of CUN-BAE with BMI is 7% and with WC is 18%. Conclusions: The correlation and the degree of agreement of CUN-BAE with BMI and WC are low in individuals aged over 50, but it is higher by sex. Thus, this different criterion of obesity may have clinical applications. More studies with a gold standard are needed to evaluate the CUN-BAE in elderly adults.

En la actualidad las nanopartículas de plata son utilizadas en numerosos productos comerciales debido a sus diversas propiedades. Uno de sus usos es como alternativa a los antibióticos en la producción animal, debido a sus propiedades antimicrobianas. Es importante conocer el comportamiento y caracterizar las AgNPs y especies derivadas para comprender sus aplicaciones y los posibles efectos tóxicos en el medio ambiente y la salud humana. Para realizar la caracterización se usan distintas técnicas como EM o ICP-MS, que en muchas ocasiones se combinan con técnicas de separación como AF4 para conseguir mejores análisis. En este trabajo desde un punto de vista experimental, se plantea el uso de EAA-Llama e ICP-MS para la caracterización de AgNps y especies derivadas en aditivos alimenticios tras distintos ensayos de lixiviación para valorar las especies liberadas. Ademas se ha realizado un estudio sobre el pH y conductividad de las muestras en agua. Por un lado, se ha determinado el contenido total de especies de plata en pienso para cerdos mediante ICP-MS, utilizando un ataque en abierto y un ataque en microondas para su comparación. La digestión es necesaria para diluir la muestra y degradar la matriz. El ataque se realizo con HNO3, necesario para estabilizar la plata y con HCl para evitar la formación de AgCl(s). También se ha medido el contenido total de plata liberada en las muestras tras una lixiviación en agua mediante EAA-Llama e ICP-MS. Por último para estudiar el comportamiento teórico de distintas especies de Ag, se ha realizado una digestión "in vitro" para determinar las especies de plata liberadas a partir de patrones de Ag(I) y AgNps mediante EAA-llama. Durante la digestión se ha comprobado que las AgNps sufren cambios en sus propiedades debido a las interacciones con los fluidos, cambios de temperatura, pH, concentraciones de sales y enzimas.

In this article, a systematic literature review of 153 articles on power quality analysis in PV systems published in the last 20 years is presented. This provides readers with an overview on PQ trends in several fields related to instrumental techniques that are being used in the smart grid to visualize the quality of the energy, establishing a solid literature base from which to start future research. A preliminary appreciation allows us to intuit that higher-order statistics are not implemented in measurement equipment and that traditional instrumentation is still used for the performance of measurement campaigns, not yielding the expected results since the information processed does not come from an electrical network from 20 years ago. Instead, current networks contain numerous coupled load effects; thus, new disturbances are not simple; they are usually complex events, the sum of several types of disturbances. Likewise, depending on the type of installation, the objective of the PQ analysis changes, either by detecting certain events or simply focusing on seeing the state of the network.

Este artículo estudia el discurso político de Helios Gómez, un artista gitano comprometido con el anarquismo y el comunismo alternativamente en el tiempo de entreguerras. El análisis contextualiza su relato sobre la nueva sociedad soviética como modelo a seguir en el amplio corpus de literatura de este género y, a la vez, lo interpreta a la luz de las culturas políticas que le dan sustento. Además, propone entender la identidad gitana de este artista gráfico como clave de su capacidad para convertir un discurso común en un discurso utópico lleno de atrevimiento proyectivo, reivindicando la igualdad étnica como parte de la justicia social. El artículo atiende al entrecruzamiento de marcos identitarios diversos —políticos, de clase, étnicos— que constituyen el entramado a partir del cual se construyó una demanda de reconocimiento de derechos para la minoría gitana, marginada en los procesos de modernización política. This article studies the political discourse of Helios Gómez, a Romani artist,who committed first to anarchism and then to communism in the interwar period.The analysis sets his account of the new Soviet society as a model to follow in thecontext of the large body of literature on the genre and at the same time interprets itin the light of the political cultures on which it draws. Moreover, it sets out to understandthe Romani identity of this graphic artist as the key to his capacity for transforminga common discourse into a utopian discourse full of projective boldness,one that called for ethnic equality as part of social justice. The article addresses thedifferent intersecting identitarian contexts—political, class, ethnic—that constitutethe framework from which to claim recognition of rights for the Roma minority,marginalized in the processes of political modernization.

La historia del pueblo gitano está sin hacer y es una ocasión para revisar críticamente los paradigmas historiográficos naturalizados en la disciplina. También para plantear investigaciones auténticamente transdisciplinares. Este artículo revisa las aportaciones existentes en dos campos, el de la historia del antigitanismo y el de la formación de los estereotipos culturales sobre «lo gitano». Apuesta también por avanzar más allá de esta historia de las reacciones de la sociedad mayoritaria ante la minoría romaní, pensando la historia gitana desde dentro. Esto supone tanto una tarea de imaginación historiográfica como una preocupación por hacer del conocimiento científico un conocimiento público, abriendo los lugares de enunciación a las comunidades históricamente interpeladas como gitanas.

BACKGROUND Multimodal MRI approach is based on a combination of MRI parameters sensitive to different tissue characteristics (eg, volume atrophy, iron deposition, and microstructural damage). The main objective of the present study was to use a multimodal MRI approach to identify brain differences that could discriminate between matched groups of patients with multiple system atrophy, Parkinson's disease, and healthy controls. We assessed the 2 different MSA variants, namely, MSA-P, with predominant parkinsonism, and MSA-C, with more prominent cerebellar symptoms. METHODS Twenty-six PD patients, 29 MSA patients (16 MSA-P, 13 MSA-C), and 26 controls underwent 3-T MRI comprising T2*-weighted, T1-weighted, and diffusion tensor imaging scans. Using whole-brain voxel-based MRI, we combined gray-matter density, T2* relaxation rates, and diffusion tensor imaging scalars to compare and discriminate PD, MSA-P, MSA-C, and healthy controls. RESULTS Our main results showed that this approach reveals multiparametric modifications within the cerebellum and putamen in both MSA-C and MSA-P patients, compared with PD patients. Furthermore, our findings revealed that specific single multimodal MRI markers were sufficient to discriminate MSA-P and MSA-C patients from PD patients. Moreover, the unsupervised analysis based on multimodal MRI data could regroup individuals according to their clinical diagnosis, in most cases. CONCLUSIONS This study demonstrates that multimodal MRI is able to discriminate patients with PD from those with MSA with high accuracy. The combination of different MR biomarkers could be a great tool in early stage of disease to help diagnosis. © 2018 International Parkinson and Movement Disorder Society.

Objectives A recent study showed that Arab-Berbers GG homozygous at rs2421947(C/G) in the dynamin 3 gene (DNM3) had 12.5 years earlier age at onset of leucine-rich repeat kinase 2 (LRRK2)-associated Parkinson's disease (PD) (L2PD). We explored whether this variant modulates the L2PD age at onset in Spain. Methods We genotyped rs2421947 in 329 participants (210 L2PD patients, 119 L2PD nonmanifesting p.G2019S carriers), and marker rs356219 (A/G) in the α-synuclein gene (SNCA). Results By Kaplan Meier and Cox regression analyses, we did not find an association of the DNM3 polymorphism with L2PD age at onset. However, we found an association of the SNCA marker with up to an 11 years difference in the L2PD median age at onset (58 years for GG carriers vs 69 years for AA). Conclusion Our results indicate that SNCA rs356219 but not dynamin 3 DNM3 rs2421947 modifies the penetrance of the mutation G2019S in the Spanish population by influencing the L2PD age at onset. These findings suggest that different genetic modifiers may influence the L2PD age at onset in different populations. © 2018 International Parkinson and Movement Disorder Society.

Professional development programs in the form of learning communities offer teachers the possibility to improve their practice and support them in accomplishing the demands that the government and society have assigned them when these are well designed and developed. The study reported here focused on understanding how an English teacher changed her teaching practice with the support of a facilitator in a teacher learning community. Data was gathered through interviews, class observations, recorded meetings and teachers’ planning units and pedagogical materials. Results indicate that the teacher experienced changes in her teaching practice related to patterns of teaching behavior and teaching methodology. However, there were some aspects of these two components that she changed only to a certain extent. Moreover, she underwent some difficulties with students and with some contextual factors that affected her learning process. This study reveals several contributions that a learning community can offer to in-service teachers to improve their teaching practice.

El tabaquismo es un problema de salud publica dado que el consumo es cada vez mayor y presenta edades de inicio mas tempranas; en relacion con los procesos biologicos del tabaquismo se han identificado varios genes cuyas variantes han sido asociadas con este fenomeno. El objetivo de este estudio fue evaluar la relacion entre los polimorfismos rs6801272 y rs680244 en los genes CYP2A6 y CHRNA5 respectivamente, con el consumo de tabaco. Para esto se realizo un estudio de casos (fumadores-exfumadores versus controles), controlando las variables edad y sexo, ademas de considerar la edad de inicio y el numero de cigarrillos por dia. El locus rs6801272 se encontro monomorfico en la poblacion de estudio, presentando el alelo T asociado con el metabolismo normal de la nicotina; aunque el locus rs680244 se encontro polimorfico, no fue posible establecer la relacion de esta variante genetica con el consumo de cigarrillos (OR 3,2) o la capacidad de abandono (OR 5,3); tampoco fue posible establecer una correlacion entre el genotipo y el numero de cigarrillos por dia (R 2 = 0,001) o el genotipo y la edad de inicio (R 2 =0,015). En conclusion, no se detecto una relacion entre las variantes geneticas estudiadas y el consumo, la capacidad de abandono, el numero de cigarrillos por dia y la edad de inicio en la poblacion de Itagui.

Introduction. Among patients with mental illness, dual disorders patients are characterized by a heterogeneous and more severe clinical presentation that is difficult to treat. Therefore, knowledge about the distribution of this disorder and the characteristics of these patients can be helpful to optimize and organize health resources. Objective. To explore the prevalence and socio-demographic and clinical factors associated with dual disorders patients who were hospitalized due to mental illness at a psychiatric unit in Colombia between January and June 2013; this data was collected and analyzed on the basis of the medical records of each patient. Method. Observational, quantitative, cross-sectional study of a secondary source. It included the analysis of 201 patients aged 18 to 65. Results. There were 201 patients analyzed; 45.3% had dual disorders, with a ratio of 2.24 men:women; there was a high frequency of single marital status (69.2%) and more than 90% had a low socioeconomic level. The factors significantly associated with dual disorders in order of importance were: age from 18 to 35 years (OR = 11.03; CI 95% [4.43, 27.46]), male (OR = 5.10, CI 95% [2.26, 11.50]), history of aggression (OR = 3.35; CI 95% [1.63, 6.91]), and readmission in the year after hospital discharge (OR = 2.23; CI 95% [1.08, 4.61]). Discussion and conclusion. Dual disorders prevalence in this study is similar to that found by other authors. The high prevalence of dual disorders requires specialized therapeutic programs for treatment. The more hospitals know about the associated variables in this study, the more they will be able to improve their approach to patients.

Objective:To assess the value of baseline clinical and imaging biomarkers in a cohort of asymptomatic LRRK2 G2019S carriers for predicting conversion to Parkinson disease (PD) at 4 years.Methods:Thirty-two asymptomatic carriers of LRRK2 G2019S mutation underwent baseline and 4-year evaluation including clinical examination (Unified Parkinson's Disease Rating Scale, part III, olfaction University of Pennsylvania Smell Identification Test [UPSIT]) and dopamine transporter (DaT) SPECT (123I-ioflupane). Visual and semiquantitative analysis of images was performed. The specific striatal binding ratio was calculated (striatal region of interest [ROI] − occipital ROI/occipital ROI).Results:Three carriers, asymptomatic at baseline, had converted to PD at 4-year evaluation. Twenty-three participants were fully evaluated. PD converters had lower striatal DaT binding at baseline than nonconverters (p = 0.002). A baseline scan with a ratio of bilateral striatal uptake below 1 predicted conversion to PD within the 4-year period with high sensitivity and specificity (area under the curve 1; p = 0.006). The slope of DaT binding decline between the 2 scans was similar in PD converters and nonconverters. Age-adjusted UPSIT score at baseline and at 4 years was similar in both groups.Conclusions:Semiquantitative DaT-SPECT could be used to predict early conversion to PD in asymptomatic carriers of the LRRK2 G2019S mutation. Rate of conversion to PD at 4 years in this cohort aged ∼64 years was 12%. The slope of DaT binding decline on DaT-SPECT imaging seems to be similar across different stages of the premotor period.

Mio-Pliocene hypabyssal rocks of the Combia event in the Amaga basin (NW Andes-Colombia), contain a deformational record of the activity of the Cauca-Romeral fault system, and the interaction of terranes within the Choco and northern Andean blocks. Previous paleomagnetic studies interpreted coherent counterclockwise rotations and noncoherent modes of rotation about horizontal axes for the Combia intrusives. However, rotations were determined from in-situ paleomagnetic directions and the existing data set is small. In order to better understand the deformational features of these rocks, we collected new paleomagnetic, structural, petrographic and magnetic fabric data from well exposed hypabyssal rocks of the Combia event. The magnetizations of these rocks are controlled by a low-coercivity ferromagnetic phase. Samples respond well to alternatingfield demagnetization isolating a magnetization component of moderate coercivity. These rocks do not have ductile deformation features. Anisotropy of magnetic susceptibility and morphotectonic analysis indicate that rotation about horizontal axes is consistently to the south-east, suggesting the need to apply a structural correction to the paleomagnetic data. The relationships between magnetic foliations and host-rock bedding planes indicate tectonic activity initiated before ~10 Ma. We present a mean paleomagnetic direction (declination D = 342.8°, inclination I = 12.1°, 95% confidence interval α95 = 12.5°, precision parameter k = 8.6, number of specimens n = 18) that incorporates structural corrections. The dispersion S = 27° of site means cannot be explained by secular variation alone, but it indicates a counterclockwise rotation of 14.8° ± 12.7° relative to stable South America. Paleomagnetic data within a block bounded by the Sabanalarga and Cascajosa faults forms a more coherent data set (D = 336.5°, I = 17.4°, α95 = 11.7°, k = 12.5, n = 14), which differs from sites west of the Sabanalarga fault and shows a rotation about a vertical axis of 20.2° ± 10.7°. Deformation in the Amaga basin may be tentatively explained by the obduction of the Canas Gordas terrane over the northwestern margin of the northern Andean block. However, it can also be related to the local effects of the Cauca-Romeral fault system.

Background and Aim The need for endoscopic investigation in patients with iron deficiency without anemia (ID) is not established. Methods Data from patients with ID (serum ferritin ≤20 ng/mL, normal hemoglobin) studied with upper and lower endoscopy were retrospectively analyzed. Patients evaluated for iron deficiency anemia (IDA) served as controls, matched by sex and age in a proportion 2:1. Presence, type, location and age distribution of endoscopic findings were compared. Results 109 patients (55% females; mean age 59.6 ± 13.5 years; age distribution

New detrital zircon-fission track (ZFT) and magnetic fabric data are presented to constrain the time of deposition, provenance and deformation of the of Lower and Upper members of the Amaga Formation in the Amaga Basin. The Amaga Basin is located in the northern Andes, between the Western and Central Cordilleras of Colombia. The Amaga Formation was deposited in a transpressive geodynamic context and is allegedly synchronous with tectonic events such as the Andean orogeny and the Panama-Choco Block collision with the northwestern South American Plate. Detrital ZFT data confirm an Oligocene age for the Lower Member and a middle-Miocene age for the Upper Member of the Amaga Formation. In addition to constraining the depositional age, the ZFT data presented in this study also reflect Paleocene-Eocene, late to early Oligocene and late to middle Miocene cooling in sediment source areas mainly located in the Central and Western Cordilleras of Colombia. These ages can be associated with regional exhumation events in the central and northern Andes of South America. Collisional stages of the Panama-Choco Block against northwestern South America, subduction of the Farallon-Nazca Plate and strike-slip reactivation periods of the Cauca-Romeral fault system, caused NW-SE compression and NE-SW simple shear in the Amaga Basin. This deformational regime, identified by magnetic fabric data, induces syn- and post-depositional deformation over the Amaga Formation.

This paper presents a novel virtual instrument for PQ assessment, based in higher-order statistics. It implements a new power-quality index, which is thought to trigger the measurement procedure when an electrical fault comes about. The user interfaces include not only the online variance charts but also the skewness and kurtosis graphs, along with hybrid representations of variance versus higher-order statistics. Designed on the basis of 85 signals recorded, 50 Hz real-time with different disturbances. The instrument validates the PQ procedure during online sessions. The new monitoring strategy activates the analysis of the signal once the PQ index overpassed a predefined threshold. Results show that voltage sags and transients are classified within different clusters, with low uncertainty, using different types of graphs. This flexibility may allow the operator to reduce the subjectivities during the online monitoring session with an optimal computational solution.

Different forecasting methodologies, classified into parametric and nonparametric, were studied in order to predict the average concentration of P M 10 over the course of 24 h. The comparison of the forecasting models was based on four quality indexes (Pearson&rsquo, s correlation coefficient, the index of agreement, the mean absolute error, and the root mean squared error). The proposed experimental procedure was put into practice in three urban centers belonging to the Bay of Algeciras (Andalusia, Spain). The prediction results obtained with the proposed models exceed those obtained with the reference models through the introduction of low-quality measurements as exogenous information. This proves that it is possible to improve performance by using additional information from the existing nonlinear relationships between the concentration of the pollutants and the meteorological variables.

En 1977 Monde Gitan, una revista francesa dedicada a la llamada “cuestión gitana”, publicó un artículo titulado Les survivants de l’Apocalypse, de Jean Ortica, integrante de una conocida familia ‘gitana’ del país. Se trata de un breve relato de ciencia ficción centrado en una catástrofe nuclear. En la historia, una familia de supervivientes debe aprender a vivir desde cero, sin poder apoyarse en la herencia de siglos de civilización. Son los romaníes quienes se sienten, en consecuencia, protagonistas de la historia de la humanidad y responsables del nacimiento de un nuevo mundo. Este relato puede ser leído de varias maneras, desde una historia de ciencia ficción distópica hasta una utopía gitana; incluso, podría ser entendido como un intento de adoctrinamiento asimilacionista por parte de la sociedad mayoritaria, desde una visión “civilizatoria”. El artículo explora estos múltiples sentidos como vía de entrada para el estudio de la situación del pueblo romaní en la Francia (y la Europa) de posguerra, teniendo en cuenta los factores sociales y culturales del contexto histórico -señaladamente, el miedo atómico propio de la Guerra Fría- pero también la situación del pueblo romaní tras el Holocausto nazi. Se trata de una forma de representar y combatir el anti-gitanismo desde la imaginación de la capacidad de agencia en un contexto de ficción extremo In 1977 Monde Gitan, a French journal devoted to the so-called “Gypsy Question” published an article entitled “Les survivants de l’Apocalypse”. Its author was Jean Ortica, a member of a well-known “gypsy” family in France. It was a Science Fiction short story portraying a nuclear disaster. The narration stresses on how a surviving Roma family have to adapt and live starting from scratch, incapable of relying on the inherited history of centuries of civilization. The Roma are the people who thus play the main role in the new history of the humankind, feeling responsible for the birth of a new world. This story can be read in several ways, from a dystopian science fiction story to a gypsy utopia narration; It could even be understood as an attempt at assimilationist indoctrination by the majority society, from a "civilizatory” vision. The article explores these multiple meanings in connection with the study of the situation of the Roma people in post-war France (and Europe), taking into account the social and cultural factors of the historical context - remarkably, the rise of nuclear fear in the Cold War- but also the situation of the Roma people after the Nazi Holocaust. This story represents and faces antigypsyism from the self-imagination of the Roma capacity for agency within a fictionalized extreme context HERA Joint Research Programme BESTROM HERA 2002 Ministerio de Economia, Industria y Competitividad (MINECO).

En la actualidad, las nanopartículas de plata (AgNPs) son ampliamente comercializadas en el mercado mundial debido a sus diversas propiedades.En este trabajo se ha utilizado la técnica de Espectroscopia de Absorción Atómica en llama (EAA-llama) para la determinación y caracterización de especies de plata en patrones de AgNPs y en suplementos alimenticios. Para caracterizar las diferentes especies de Ag se ha realizado la separación física de AgNPs y Ag+ mediante la técnica de ultrafiltración, previamente a su determinación por EAA-llama. Además, se ha llevado a cabo la caracterización de AgNPs de 10, 20, 40 y 60 nm mediante Cromatografía Hidrodinámica (HDC) con detección UV-VIS, y se han optimizado las fases móviles empleadas teniendo en cuenta los parámetros cromatográficos y de recuperación obtenidos. Por último, se ha llevado a cabo la caracterización de AgNPs y Ag+ directamente mediante HDC-ICP-MS, poniendo interés en conseguir una eficiente separación entre los distintos tamaños de AgNPs y la Ag+. En base a estos resultados, se ha procedido a la cuantificación de AgNPs y Ag+ en suplementos alimenticios mediante HDC-ICP-MS.

Psoriasis is a multisystem disease which has been related to vitamin‑D deficiency through chronic inflammation. This psoriasis‑related inflammatory state and vitamin‑D deficiency may induce bone mineral density loss. The purpose of this study is to assess the relationship of psoriasis with bone mineral density, by comparing psoriatic patients with healthy controls and patients with osteopenia/osteoporosis. Psoriatic patients showed worse hip and lumbar spine bone mineral density levels than healthy controls (P = 0.001) and better levels than osteoporotic patients (P < 0.001). Multivariate analysis demonstrated a negative association of age and a positive association of body mass index in hip bone mineral density in psoriatic patients. Bone mineral density levels in psoriatic patients are situated halfway between healthy controls and patients with osteopenia/osteoporosis. In addition, the higher body mass index in patients with psoriasis appears to confer a protective effect against further development of lower bone mineral density.
