En esta investigación se presenta la validez estructural, la invarianza y fiabilidad de la medida en universitarios peruanos. Se seleccionaron intencionalmente 859 estudiantes de Psicología, entre 17 y 39 años, de dos universidades de Lima Metropolitana. El análisis factorial confirmatorio realizado sobre tres modelos: modelo 1, replica la estructura original; modelo 2, analiza la estructura original sin los ítems redactados en forma negativa; modelo 3, se excluyeron los ítems inversos y los que presentaban varianza irrelevante de constructo (ítem 9). Este último modelo es el que presenta un mejor ajuste (CFI = .924; RMSEA = .091; SRMR = 0.058). Sobre este modelo se estableció la invarianza configuracional, métrica, escalar y residual según edad. Adicionalmente, se prob...

This study aimed to characterize the chemical composition of wild and cultured fish. The muscle proximate composition, and fatty acid and amino acid profiles were assessed. The cultivated specimens showed a higher lipid content and lower protein and ash contents compared with the wild specimens. The predominant tissue fatty acids in both the wild and cultivated fish were palmitic acid (16:0), oleic acid (18:1n-9) and docosahexaenoic acid (DHA, 22:6n-3). A higher content of arachidonic acid (ARA, 20:4n-6), eicosapentaenoic acid (20:5n-3) and DHA were detected in the muscle of wild mullets, while the fish supplied with commercial pellets showed higher quantities of monounsaturated fatty acids, and lower quantities of saturated fatty acids a...

Recently, we unveiled that in the gilthead seabream (Sparus aurata), the G protein-coupled estrogen receptor agonist G-1 (G1) and the endocrine disruptor 17α-ethinylestradiol (EE2) are potent modulators in polyreactive antibody production. However, the integral role of the microbiota upon immunity and antibody processing in response to the effect of EE2 remains largely unexplored. Here, juvenile seabreams continuously exposed for 84 days to oral G1 or EE2 mixed in the fish food were intraperitoneally (i.p.) immune primed on day 42 with the model antigen keyhole limpet hemocyanin (KLH). A critical panel of systemic and mucosal immune markers, serum VTG, and humoral, enzymatic, and bacteriolytic activities were recorded and correlated with gut bacterial metagenomic analysis 1 day post-priming (dpp). Besides, at 15 dpp, animals received a boost to investigate the possible generation of specific anti-KLH a...

Es así como el autor se enfoca, como premisa del texto, a realizar un estudio analítico, crítico y constructivo del financiamiento de los partidos políticos en los ámbitos internacional y nacional, centrándose en las situaciones que imperan en México, a través de un recorrido por la historia del sistema político mexicano, desde la época del Partido Revolucionario Institucional (PRI) gobierno hasta la actual administración de Felipe Calderón Hinojosa, resaltando el marco jurídico electoral y la jurisprudencia observable en esta materia, con sus aciertos y desaciertos, vacíos e imprecisiones normativas

Although its pathogenic implication has been clearly established, its taxonomical inclusion and virulence mechanisms are not still completely elucidated. In the present work, we have studied the outer membrane protein (OMP) and lipopolysaccharide (LPS) patterns and other antigenic characteristics of Vibrio P1 strains, and we have compared to those both reference strains of Vibrio and Vibrio strains isolated from diseased clams, by means of SDS-PAGE, immunoblotting, Western blot, slide agglutination and dot-blot techniques.The present results strongly suggest that Vibrio P1 constitutes a homogeneous group on the basis of its antigenic characteristics. Although this microorganism shares common epitopes with several Vibrio species, antigenic heterogeneity with regard to both LPS-structure and OMP-pattern is presented.
