Urban ecology of Triatoma infestans in San Juan, Argentina

This study was performed in an urban neighborhood of the capital city of the province of San Juan, Argentina. Erected as a housing complex, the place consists of 768 flats distributed in buildings of three and seven floors each. A survey was carried out in 33% of the dwellings, enquiring about the number of Triatoma infestans found indoors, stage of the bug development - nymph or adult - and how these insects had entered their homes. Adult T.infestans were found on all floors; 163 people (64%) had found them at least once, and 130 (51%) several times. Dispersal flight seems to have been the main mechanism of infestation by adult bugs in this area, and a total of 51% of the surveyed inhabitants reported that the insects had flown into their flats.

Mutations at a single codon in Mad homology 2 domain of SMAD4 cause Myhre syndrome.

Myhre syndrome (MIM 139210) is a developmental disorder characterized by short stature, short hands and feet, facial dysmorphism, muscular hypertrophy, deafness and cognitive delay. Using exome sequencing of individuals with Myhre syndrome, we identified SMAD4 as a candidate gene that contributes to this syndrome on the basis of its pivotal role in the bone morphogenetic pathway (BMP) and transforming growth factor (TGF)-β signaling. We identified three distinct heterozygous missense SMAD4 mutations affecting the codon for Ile500 in 11 individuals with Myhre syndrome. All three mutations are located in the region of SMAD4 encoding the Mad homology 2 (MH2) domain near the site of monoubiquitination at Lys519, and we found a defect in SMAD4 ubiquitination in fibroblasts from affected individuals. We also observed decreased expression of downstream TGF-β target genes, supporting the idea of impaired TGF-β-mediated transcriptional control in individuals with Myhre syndrome.

Un análisis descriptivo de la traducción de los dialectos geográficos y sociales italianos al castellano: el caso de Il cane di terracotta de Andrea Camilleri

El éxito internacional de Andrea Camilleri, escritor siciliano cuyas novelas están caracterizadas por la presencia del dialecto, ha fomentado el debate sobre la posibilidad de traducir textos caracterizados por la presencia de variación lingüística. Esta cuestión ha sido tratada de forma marginal por la traductología y, a menudo, los estudiosos han abogado por la supresión de las marcas dialectales en las traducciones. Un análisis del sistema lingüístico italiano y de su literatura, sin embargo, no puede prescindir del estudio de los dialectos y de las variedades regionales, cuya presencia es todavía muy fuerte. El presente trabajo se centra en un análisis descriptivo, de tipo cualitativo y cuantitativo, de las réplicas de tres personajes de la novela de Camilleri Il cane di terracotta en la versión original y en su traducción al castellano. Este estudio, suportado por la descripción del marco teórico en el que se inscribe el tema de la variación lingüística, nos permite, en primer lugar, evaluar el peso de la presencia de marcas de dialecto geográfico y social en el texto original y trazar la compleja relación existente entre lengua nacional, dialectos y variedades regionales en Italia. En segundo lugar, a través del análisis de la versión en castellano podremos verificar si existe una supresión considerable de las marcas dialectales en la traducción

L'evasione di Pietro e la morte del tiranno. Echi Intertestuali in At 12

Skin permeation and metabolism of di(2-ethylhexyl) phthalate (DEHP).

Phthalates are suspected to be endocrine disruptors. Di(2-ethylhexyl) phthalate (DEHP) is assumed to have low dermal absorption; however, previous in vitro skin permeation studies have shown large permeation differences. Our aims were to determine DEHP permeation parameters and assess extent of skin DEHP metabolism among workers highly exposed to these lipophilic, low volatile substances. Surgically removed skin from patients undergoing abdominoplasty was immediately dermatomed (800 μm) and mounted on flow-through diffusion cells (1.77 cm(2)) operating at 32°C with cell culture media (aqueous solution) as the reservoir liquid. The cells were dosed either with neat DEHP or emulsified in aqueous solution (166 μg/ml). Samples were analysed by HPLC-MS/MS. DEHP permeated human viable skin only as the metabolite MEHP (100%) after 8h of exposure. Human skin was able to further oxidize MEHP to 5-oxo-MEHP. Neat DEHP applied to the skin hardly permeated skin while the aqueous solution readily permeated skin measured in both cases as concentration of MEHP in the receptor liquid. DEHP pass through human skin, detected as MEHP only when emulsified in aqueous solution, and to a far lesser degree when applied neat to the skin. Using results from older in vitro skin permeation studies with non-viable skin may underestimate skin exposures. Our results are in overall agreement with newer phthalate skin permeation studies.

Estudio del ecosistema urbano de San José. Protocolo de monitoreo de aves y naturalización del Parque La Sabana

El papel de la ciudad en el futuro de la humanidad será transcendente, y es que el crecimiento actual de los espacios urbanos tiende, en general, a desbordar el sitio original de las ciudades, abarcando territorios cada vez más extensos y discontinuos. Y por este motivo es de vital importancia el estudio de la ciudad y de su entorno, el cual es sinónimo de ecosistema urbano. En el siguiente estudio se evalúa el ecosistema urbano de San José, capital de Costa Rica, dando énfasis en las zonas verdes presentes, en las relaciones con los ecosistemas naturales circundantes y como mejorar su capacidad ecológica. Por este motivo se ha analizado un proceso de rearborización en el Parque Metropolitano La Sabana, principal nódulo de carga de la trama urbana. Este esfuerzo de naturación dotará al parque de una mayor naturalización, con lo que se espera un aumento de la biodiversidad faunística. Para conocer estos cambios se crea un programa de monitoreo de aves con su respectivo protocolo.

La prima storia del cristianesimo

Come Luca progettò la sua storia raccontata nel Vangelo e negli Atti? Come identificare le unità letterarie e teologiche? Uno studio critico di alto livello che affronta le problematiche connesse alla stesura del testo degli Atti degli Apostoli in parallelo al Vangelo di Luca, identifica le ambivalenze e le questioni teologiche della Chiesa primitiva, delinea la fisionomia dei protagonisti (Paolo, Barnaba, Pietro, Timoteo e gli altri) concentrando l'attenzione in modo particolare su At 5,1-11 e At 9; 22 e 26 come passaggi critici e illuminanti.
