Programa de educación de las emociones: la con-vivencia. Evaluación de su eficacia en la conducta prosocial
2014
La educación de las emociones se sitúa en el marco de la psicología positiva (Seligman, 2000). En el desarrollo humano las emociones juegan un papel fundamental, especialmente, como los patrones de respuesta y ejercen un importante valor adaptativo, personal y social (Fredickson, 2001). Una respuesta emocional adaptada ante las situaciones cotidianas facilita la comunicación tanto con uno mismo y como con los demás. Así, la estimulación de las emociones positivas contribuye al desarrollo de la personalidad y a una mayor calidad de las relaciones interpersonales, favoreciendo una conducta más adaptada y prosocial. Diferentes estudios empíricos constatan que, tanto determinadas emociones, com…
Creatividad e imaginación: Análisis y evaluación del programa CREA para escolares en el seguimiento de 8-12 años.
2017
El trabajo que presentamos surge del deseo de profundizar en el análisis que, en el momento actual, plantea el fomento y desarrollo de la creatividad. Tras realizar un recorrido por diversos planteamientos teóricos y de investigación llevados a cabo en el ámbito creativo en el tiempo; se han abordado en un segundo momento, las aportaciones que al fomento de la creatividad se están llevando a cabo hoy, desde la investigación en el campo de la neurociencia y de la imaginación moral, para posteriormente, profundizar en la relación de esta con la conducta prosocial. En el apartado empírico, se ha llevado a cabo un análisis longitudinal a diversos grupos de escolares en el seguimiento de 8 y 12 …
Revista electrónica de investigación y evaluación educativa
2014
Resumen basado en el de la publicación Título, resumen y palabras clave en inglés y español Se pretende comprobar de forma experimental la asunción teórica que plantea la posibilidad de fomentar el potencial creativo de acuerdo con las condiciones ambientales que el medio proporciona. Para ello, se diseñó un programa psicoeducativo basado en cuentos infantiles, con el fin de estimular la capacidad creativa en niños de Educación Infantil. Para la medición de la creatividad se utilizaron la Batería Gráfica y Verbal de Test de Pensamiento Creativo de Torrance. Tras la aplicación del programa, los resultados arrojaron un incremento significativo en los niveles de creatividad verbal en el grupo …
Parental expectations and prosocial behavior of adolescents from low-income backgrounds. A cross-cultural comparison between three countries: Argenti…
2014
Parental expectations are influenced by cultural models, which in turn are subject to a great influence from historically fluctuating features of the socioeconomic background. Parental expectations seem to be linked to children’s social and emotional development in terms of empathy and prosocial behavior. The current study aims to (a) compare low-income adolescents’ perceptions of parental expectations of prosocial and antisocial behavior across three Latin countries (Argentina, Colombia, and Spain), (b) compare the empathy and prosocial behavior between the three countries, (c) compare the prosocial behavior between the three countries, and (d) study the effect of perceived parental expect…
Enhancement of premature stop codon readthrough in the CFTR gene by Ataluren (PTC124) derivatives.
2015
Abstract Premature stop codons are the result of nonsense mutations occurring within the coding sequence of a gene. These mutations lead to the synthesis of a truncated protein and are responsible for several genetic diseases. A potential pharmacological approach to treat these diseases is to promote the translational readthrough of premature stop codons by small molecules aiming to restore the full-length protein. The compound PTC124 (Ataluren) was reported to promote the readthrough of the premature UGA stop codon, although its activity was questioned. The potential interaction of PTC124 with mutated mRNA was recently suggested by molecular dynamics (MD) studies highlighting the importanc…
Inhalable nano into micro dry powders for ivacaftor delivery: The role of mannitol and cysteamine as mucus-active agents.
2020
In this paper the innovative approach of Nano into micro (NiM9 was developed to produce Nanoparticles loaded Ivacaftor to incorporate into mannitol or mannitol/cysteamine micromatrices for drug pulmonary administration in CF. Nanoparticles composed by a mixture of two polyhydrohydroxyethtylaspartamide copolymers containing a loading of Ivacaftor of 15.5 % w/w were produced. These Nanoparticles were incorporated into microparticles to obtain NiM that were characterized in terms of size and size distribution, interaction with CF-AM by rheological and turbidimetric studies as well as by aerodynamic diameter measurements. Finally the activity of Ivacaftor into these NiM was evaluated by in vitr…

Impaired Transporter Associated with Antigen Processing (TAP) Function Attributable to a Single Amino Acid Alteration in the Peptide TAP Subunit TAP1
2003
Abstract The heterodimeric peptide transporter TAP belongs to the ABC transporter family. Sequence comparisons with the P-glycoprotein and cystic fibrosis transmembrane conductance regulator and the functional properties of selective amino acids in these ABC transporters postulated that the glutamic acid at position 263 and the phenylalanine at position 265 of the TAP1 subunit could affect peptide transporter function. To define the role of both amino acids, TAP1 mutants containing a deletion or a substitution to alanine at position 263 or 265 were generated and stably expressed in murine and human TAP1−/− cells. The different TAP1 mutants were characterized in terms of expression and funct…
Characterization of Emergence of the Coulomb Blockade in a Pearl-Like DNA-AuNP Assembly
2023
Due to its superior self-assembly properties and vast functionalization pos-sibilities DNA has long been one of the most promising candidates forfabrication of nanoscale electrical components using molecular buildingblocks. There exist already many demonstrations on optical devices based onorganizing metallic nanoparticles (NP) via DNA self-assembly, but despite thepromises only few DNA based electrical devices or studies have been realizedso far. Here we study the gold NP conjugated and metallized DNA TX-tile-structure, which we recently showed to exhibit the room temperature Coulombblockade, the pre-requisition for a single electron transistor. The properties ofthe obtained Coulomb blocka…
