This paper aims to present the understanding of the relationship between administrative quality service and satisfaction, engagement, and performance of higher education students in the Latin American context. Researcher studied the impact of quality in natural science students at the University of Costa Rica, using a mixed method (quantitative-qualitative) to compare the information. Researcher found that quality service impacts satisfaction but not engagement. None of the above have an impact on performance. It was possible to identify that those students understand satisfaction as a consequence of academic service, while engagement is relative to the other elements of the university context. Finally, performance is unrelated to the aspects studied.

El presente artículo pretende comprender la relación que existe entre la calidad del servicio administrativo, la satisfacción, el compromiso y el rendimiento de los estudiantes universitarios, en procura de una visión desde la perspectiva latinoamericana. Se investigó el impacto que tiene esta calidad en una población de estudiantes del área de ciencias básicas de la Universidad de Costa Rica. Para ello se empleó un esquema mixto de investigación (cuantitativa-cualitativa) para contrastar la información obtenida. Se determinó que el estudiantado considera que la calidad del servicio impacta su satisfacción, pero no así el compromiso. Además, ninguno de los aspectos anteriores tiene influencia sobre su rendimiento. Se identificó que las personas estudiantes entienden que la satisfacción es producto del servicio académico y que el compromiso se asocia a otros elementos en el contexto universitario. Finalmente, el rendimiento aparece desvinculado a los aspectos estudiados.

The majority of snakebite envenomations in Central America are caused by the viperid species Bothrops asper, whose venom contains a high proportion of zinc-dependent metalloproteinases that play a relevant role in the pathogenesis of hemorrhage characteristic of these envenomations. Broad metalloproteinase inhibitors, such as the peptidomimetic hydroxamate Batimastat, have been shown to inhibit snake venom metalloproteinases (SVMP). However, the difficulty in having open public access to Batimastat and similar molecules highlights the need to design new inhibitors of SVMPs that could be applied in the treatment of snakebite envenomations. We have chosen the SVMP BaP1 as a model to search for new inhibitors using different strategies, that is, screening of the Prestwick Chemical Library and rational peptide design. Results from these approaches provide clues on the structural requirements for efficient BaP1 inhibition and pave the way for the design of new inhibitors of SVMP.
