Perfluoroalkyl substances and immune cell counts in adults from the Mid-Ohio Valley (USA)
2021
Highlights • The literature on PFASs and circulating levels of immune cells is scarce. • Study of the association between PFASs and white blood cells at two different time points. • Cross-sectional study on the association between PFASs and lymphocyte subsets. • Positive association between PFHxS and total lymphocytes, especially for cell count. • Positive, but less consistent, association between PFOA and PFOS and total lymphocytes.
The influence of organizational factors on road transport safety
2018
Road transport safety is a major concern across Europe due to the human and socio-economic costs associated with work-related traffic accidents. Traditional approaches have adopted regulatory and technical measures to prevent road accidents leaving aside the organizational factors that might contribute to road transport safety. However, contemporary sociotechnical systems theory acknowledges the need to take into account organizational factors. This study adopts a sociotechnical approach and it examines the relationship between a number of organizational factors (organizational learning and training) and road traffic accidents in the organizations under study. Our sample was composed of 107…
La asistencia a juicios y su simulación como nuevos métodos de aprendizaje del Derecho procesal
2014
El presente artículo tiene como fin analizar dos métodos de enseñanza en los que el alumno participa de forma activa: la asistencia a juicios y la simulación de procesos. Estas actividades producen buenos resultados en el aprendizaje del Derecho Procesal, según se desprende de diferentes encuestas en las que se evalúan algunas experiencias docentes
Extraprostatic Spindle Cell Stromal Tumor of the Prostate: Case Report
2007
Several benign and malignant nonepithelial and stromal-like lesions arise in the prostate. Because such lesions are rare, their recognition is essential, because treatment and prognosis depend on an adequate pathohistologic classification. We report a case of an 83-year-old man with a stromal tumor of the prostate of uncertain malignant potential (STUMP). He presented with urinary retention and rectal constipation. On bimanual examination, a rectally and suprapubically palpable mass was found. Imaging studies revealed a 12 x 8 cm pararectal inhomogeneous mass of uncertain origin compressing rectum and urethra. The tumor was resected by a retropubic approach and examined immunohistochemicall…
La agricultura a tiempo parcial y la externalización de servicios agrarios como vehículo del cambio estructural
2010
El «ajuste clásico» ha sido interpretado frecuentemente como la senda racional y óptima de modernización del sector agrario. Esto ha llevado a considerar a la agricultura a tiempo parcial como un subproducto (ineficiente) del modelo clásico. Frente a este planteamiento, el artículo defiende la potencial contribución de la agricultura a tiempo parcial (y la externalización de servicios asociada a la misma) al proceso de innovación y de modernización de las estructuras agrarias. Se revisa críticamente la literatura adoptando una perspectiva microeconómica y territorial y esbozando un marco analítico que combina los enfoques de los costes de transacción y evolucionista. Utilizando información …

Data from: Moving in the Anthropocene: global reductions in terrestrial mammalian movements
2019
Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral changes of individual animals and to the exclusion of species with long-range movements from areas with higher human impact. Global loss of vagility alters a key ecological trait of animals that affects no…
Dual emission of a bis(pyrene)-functionalized, perbenzylated beta-cyclodextrin
2008
A bis(pyrene)-functionalized β-cyclodextrin (1) has been prepared in two steps from perbenzylated β-cyclodextrin. This compound shows dual emission properties, which arise from the pyrenyl chromophores. Upon excitation of 1 at 355 nm, monomer blue fluorescence (386, 407 and 428 nm) is observed in DMSO solution, whereas excimer green fluorescence (477 nm) is seen upon addition of ≥20 vol% water in DMSO. This suggests that modified β-cyclodextrin 1 changes its shape in response to the environment. The sensing properties of 1 towards carboxylic acids and alcohols were investigated in H2O–DMSO (80 : 20 v/v). Monomer fluorescence is restored selectively by medium length normal carboxylic acids, …
Poética de la espera. Una filosofía íntima (con fragmentos de Proust y Pizarnik)
2013
Resumen: Frente a una forma mas o menos publica, academica e impersonal de filosofar, este texto aspira a poner en practica una filosofia intima . A partir de algunos fragmentos de Proust y Pizarnik, el proposito de este texto es ofrecer una reflexion sobre una poetica de la espera . La espera es el tiempo de la duracion, del tedio y del aburrimiento, un tiempo a nuestro tiempo acelerado, medido y previsible. Se trata, sin duda, del tiempo de un aprender involuntario. Palabras clave : Poetica de la espera, filosofia del amor, aprendizaje involuntario, Marcel Proust, Alejandra Pizarnik. Abstract: Faced with a more or less public, academic and impersonal philosophy, this text aims to impleme…
