Remote laboratories allow experimentation at distance and offer access to education. This work presents the development of an application that integrates haptics to remote laboratories to improve experiments whose comprehension involves mechanical material characterization. 1.

This is due to the ever increasing demand for oil derivatives in the international market. The extraction of this mineral, however, is not an easy process. It poses many hazards which may threaten the environment and the lives of workers at an oil well. In order to reduce the chances of accidents

Previously, we have reported on the induction of strong immunogenicity in dogs upon vaccination with LdCen(-/-) including an increase in immunoglobulin isotypes, higher lymphoproliferative response, higher frequencies of activated CD4(+) and CD8(+) T cells, IFN-γ production by CD8(+) T cells, increased secretion of TNF-α and IL-12/IL-23p40 and, finally, decreased secretion of IL-4. To further explore the potential of LdCen(-/-) parasites as vaccine candidates, we performed a 24-month follow up of LdCen(-/-) immunized dogs after challenge with virulent Leishmania infantum, aiming determination of parasite burden by qPCR, antibody production (ELISA) and cellular responses (T cell activation and cytokine production) by flow cytometry and sandwich ELISA. Our data demonstrated that vaccination with a single dose of LdCen(-/-...

In this chapter we describe the techniques more widely used for gene expression analysis and present the main findings in the search for RNA biomarkers in schizophrenia such as the recurrent observation
