Validation of an LC-ESI-MS/MS for the quantitation of phosphodiesterase-5 inhibitors and their main metabolites in rat serum and brain tissue samples.
(Elsevier, 2012-105-1)
This work proposes a liquid chromatography-electrospray ionization ion trap mass spectrometry (LC-ESI-ITMS) method, for the quantification of sildenafil (SDF), tadalafil (TDF) and vardenafil (VDF) and their metabolites ...
Fundamentos para la paralelización de IGBTs
(2016-07-06)
Las aplicaciones de electrónica de potencia requieren cada vez mayores rangos de tensión y corriente que no pueden ser alcanzados a través de dispositivos discretos. Por este motivo, surge la necesidad de realizar diseños ...
Where does risk lie in sexual practices? A study of young people’s social representations
(Taylor & Francis Group, 2020-07-13)
In this study we investigate the social representations of risky sexual practices.
Specifically, we analyse the circumstances in which young Spanish people consider
a sexual practice as risky, and how such ‘representations’ ...
Visual Programming Environments for Object Oriented Programming: Acceptance and Effects on Student Motivation
(IEEE, 2017-08-07)
This paper presents an experiment in which visual programming environments have been used in programming courses aiming at helping students to acquire the competencies of a course on object-oriented programming. This paper ...
m6A Methylated Long Noncoding RNA LOC339803 Regulates Intestinal Inflammatory Response
(Wiley, 2024-04)
Cytokine mediated sustained inflammation increases the risk to develop different complex chronic inflammatory diseases, but the implicated mechanisms remain unclear. Increasing evidence shows that long noncoding RNAs ...
In Vitro Screening and Lipid-Lowering Effect of Prickly Pear (Opuntia Ficus-Indica L. Mill.) Fruit Extracts in 3T3-L1 Pre-Adipocytes and Mature Adipocytes
(Springer Nature, 2024)
Opuntia ficus-indica fruits have been widely used due to their nutritional composition and beneficial effects on health, particularly against chronic diseases such as diabetes, obesity, cardiovascular diseases and cancer, ...
All-Polymer Nanocomposite as Salt-Free Solid Electrolyte for Lithium Metal Batteries
(ACS, 2024-01)
Solid polymer electrolytes that combine both a high lithium-ion transference number and mechanical properties at high temperatures are searched for improving the performance of batteries. Here, we show a salt-free all-polymer ...
