Este escrito tiene como fin analizar el impacto y la retroalimentación de las campañas publicitarias televisivas en los consumidores ya que algunas empresas invierten grandes sumas de dinero pautando por este medio. Se pretende aportar un estudio de mercados, en el cual se abarcara toda la perspectiva de las empresas que pueden y no pautar en televisión, hasta llegar al estudio específico, tomando como objeto de estudio una empresa y un producto. Por otro lado, se realizara una evaluación de los procesos involucrados en la cadena de valor de Porter, con el fin de ampliar la información requerida para el producto en estudio. La investigación se realizara por medio de encuestas y observaciones etnográficas y se espera definir si se debe mantener la estructura actual de pautas publicitarias o si se debe cambiar la línea de comunicación, proponiendo otras posibles alternativas.

Recurrent spontaneous abortion (RSA) is defined as the loss of three or more consecutive pregnancies during the first trimester of embryonic intrauterine development. This kind of human infertility is frequent among the general population since it affects 1 to 5% of women. In half of the cases the etiology remains unelucidated. In the present study, we used interspecific recombinant congenic mouse strains (IRCS) in the aim to identify genes responsible for embryonic lethality. Applying a cartographic approach using a genotype/phenotype association, we identified a minimal QTL region, of about 6 Mb on chromosome 1, responsible for a high rate of embryonic death (,30%). Genetic analysis suggests that the observed phenotype is linked to uterine dysfunction. Transcriptomic analysis of the uterine tissue revealed a preferential deregulation of genes of this region compared to the rest of the genome. Some genes from the QTL region are associated with VEGF signaling, mTOR signaling and ubiquitine/proteasome-protein degradation pathways. This work may contribute to elucidate the molecular basis of a multifactorial and complex human disorder as RSA.
