The peptides met- and leu-enkephalin were identified in the telencephalon, rombencephalon, diencephalon and hypophysis of Ambystoma mexicanum brain by radioimmunoassay procedure. The met-enkephalin ...was the predominant peptide present in the axolotl brain in contrast with leu-enkephalin, except in the hypophysis where the ratio MET/LEU was 2.2/l. The clear differences in the concentration between enkephalins through a submammalian brain species as Ambystoma genus and the possibility that leu-enkephalin is derived exclusively from a precursor like prodynorphin offers an excellent model for the opioids biosynthetic processes.
Several models which analyze count data have been proposed in econometric literature. These models allow the discrete, non-negative nature of specific phenomena of interest to be gathered in a ...appropriate way and can be useful for the explanation of specific preference structures among individuals. In this work, an analysis of the number of wine types consumed by residents of Tenerife is carried out, with an aim to observe which characteristics determine the exclusivity in its consumption, given the current context of increased competition in this sector. The specific characteristics of the considered variable allow the study to cover two aspects. The first is methodological, and is seen by the variety of models that may be considered in this case. This focus consists in comparing several possibilities which fit the type of count data involved. The second aspect is clearly empirical, and is based on the description of not only the most appropriate decision-making mechanism for the study but in the identification of those factors that explain the diversity in wine consumption.
Memoria ID-0075. Ayudas de la Universidad de Salamanca para la innovación docente, curso 2009-2010.
Mediante este proyecto se ha comenzado a desarrollar una herramienta (JME-X) para general de forma ...rápida estructuras electrónicas. Los estudiantes, al trabajar con JME-X refuerzan conceptos importantes aprendidos en distintas materias del área de la Química Orgánica. Las estructuras generadas se pueden almacenar en una base de datos para una posterior consulta. Esta herramienta se utiliza para llevar a cabo trabajos de fin de Grado de Farmacia de acuerdo con los nuevos planes de estudio adaptados a la Convergencia Europea del Grado de Farmacia de la Universidad de Salamanca. Además, se ha utilizado en las clases prácticas de la asignatura "Metabolitos Secundarios" impartida en la Licenciatura de Biotecnología y en varios cursos de Postgrado impartidos en distintas Universidades Latinoamericanas.
