PyCellBase, an efficient python package for easy retrieval of biological data from heterogeneous sources.
Background Biological databases and repositories are incrementing in diversity and complexity over the years. This rapid expansion of current and new sources of biological knowledge raises serious problems of data accessibility and integration. To handle the growing necessity of unification, CellBase was created as an integrative solution. CellBase provides a centralized NoSQL database containing biological information from different and heterogeneous sources. Access to this information is done through a RESTful web service API, which provides an efficient interface to the data. Results In this work we present PyCellBase, a Python package that provides programmatic access to the rich RESTfu…
Creencias sobre el aprendizaje de las ciencias de los estudiantes del máster de profesorado de enseñanza secundaria
En este trabajo se muestran los resultados de un estudio empírico sobre las creencias de futuros docentes de enseñanza secundaria acerca de los procesos de aprendizaje de la ciencia, registradas mediante un cuestionario de escala likert que han cumplimentado 188 estudiantes del Máster de Profesorado de Educación Secundaria, de las especialidades de ciencia y tecnología. En primer lugar se han clasificado las diversas creencias por su relación con diferentes modelos didácticos y se ha realizadoun estudio descriptivo para conocer cuáles son las creencias más extendidas entre tales estudiantes. Posteriormente se ha desarrollado un análisis de las relaciones internas entre tales creencias y hem…
Ultra-Performance Liquid Chromatography-Ion Mobility Separation-Quadruple Time-of-Flight MS (UHPLC-IMS-QTOF MS) Metabolomics for Short-Term Biomarker Discovery of Orange Intake: A Randomized, Controlled Crossover Study
A major problem with dietary assessments is their subjective nature. Untargeted metabolomics and new technologies can shed light on this issue and provide a more complete picture of dietary intake by measuring the profile of metabolites in biological samples. Oranges are one of the most consumed fruits in the world, and therefore one of the most studied for their properties. The aim of this work was the application of untargeted metabolomics approach with the novel combination of ion mobility separation coupled to high resolution mass spectrometry (IMS-HRMS) and study the advantages that this technique can bring to the area of dietary biomarker discovery, with the specific case of biomarker…
Effects of endodontic treatment on apparent Young’s modulus of human teeth: in vitro study using speckle interferometry
The introduction of new techniques for endodontic procedures requires the analysis of the biomechanical behavior of dental structures. Digital speckle shearing pattern interferometry (DSSPI) is a nondestructive optical measuring technique that allows one to directly quantify deformations in teeth that are subjected to stress. DSSPI technique was applied to measure small deformations caused by flexion in different types of teeth. The test was carried out both before and after endodontic treatment with the ProTaper method in order to evaluate the variation of dental elasticity, taking into the account the type of tooth and the endodontic treatment. The results obtained show that dental elasti…
