The Effects of Static and Dynamic Visual Representations as Aids for Primary School Children in Tasks of Auditory Discrimination of Sound Patterns. A…

2018

It has been proposed that non-conventional presentations of visual information could be very useful as a scaffolding strategy in the learning of Western music notation. As a result, this study has attempted to determine if there is any effect of static and dynamic presentation modes of visual information in the recognition of sound patterns. An intervention-based quasi-experimental design was adopted with two groups of fifth-grade students in a Spanish city. Students did tasks involving discrimination, auditory recognition and symbolic association of the sound patterns with non-musical representations, either static images (S group), or dynamic images (D group). The results showed neither s…

Molecular alterations in lesions of anogenital mammary-like glands and their mammary counterparts including hidradenoma papilliferum, intraductal pap…

2017

Lesions affecting anogenital mammary-like glands (AGMLG) are histopathologically very similar to those seen in the breast but whether this morphological similarity is also reflected at the genetic level is unknown. To compare the underlying molecular mechanisms in lesions of AGMLG and their mammary counterparts, we analyzed the mutational profile of 16 anogenital neoplasms including 5 hidradenomas papilliferum (HP), 1 lesion with features of HP and fibroadenoma (FA), 7 FA, 3 phyllodes tumors (PhT)) and 18 analogous breast lesions (6 intraductal papillomas (IDP), 9 FA, and 3 PhT) by high-coverage next generation sequencing (NGS) using a panel comprising 50 cancer-related genes. Additionally,…

Pharmacological preclinical characterization of LAS190792, a novel inhaled bifunctional muscarinic receptor antagonist /β 2 -adrenoceptor agonist (MA…

2017

LAS190792 is a novel muscarinic antagonist and β2-adrenoceptor agonist in development for chronic respiratory diseases. This study investigated the pharmacological profile of LAS190792 in comparison to batefenterol, tiotropium, indacaterol and olodaterol. LAS190792 is potent at the human M3 receptor (pIC50: 8.8 in binding assays). It is selective for the β2-adrenoceptor over the β1-and β3-adrenoceptor, and shows a functional potency in a similar range to batefenterol and LABA compounds (pEC50 in spontaneous tone isolated trachea: 9.6). The relaxant potency of LAS190792 in electrically stimulated tissue is similar to batefenterol, with an antimuscarinic activity in presence of propranolol sl…

Starvation resistance and tissue-specific gene expression of stress-related genes in a naturally inbred ant population

2016

Starvation is one of the most common and severe stressors in nature. Not only does it lead to death if not alleviated, it also forces the starved individual to allocate resources only to the most essential processes. This creates energetic trade-offs which can lead to many secondary challenges for the individual. These energetic trade-offs could be exacerbated in inbred individuals, which have been suggested to have a less efficient metabolism. Here, we studied the effect of inbreeding on starvation resistance in a natural population of Formica exsecta ants, with a focus on survival and tissue-specific expression of stress, metabolism and immunity-related genes. Starvation led to large tis…

Fluorinated Chaperone−β-Cyclodextrin Formulations for β-Glucocerebrosidase Activity Enhancement in Neuronopathic Gaucher Disease

2017

Amphiphilic glycomimetics encompassing a rigid, undistortable nor-tropane skeleton based on 1,6-anhydro-L-idonojirimycin and a polyfluorinated antenna, when formulated as the corresponding inclusion complexes with β-cyclodextrin (βCD), have been shown to behave as pharmacological chaperones (PCs) that efficiently rescue lysosomal β- glucocerebrosidase mutants associated to the neuronopathic variants of Gaucher disease (GD), including the highly refractory L444P/L444P and L444P/P415R single nucleotide polymorphs, in patient fibroblasts. The body of work here presented includes the design criteria for the PC prototype, the synthesis of a series of candidates, the characterization of the PC:βC…

Vitamin K antagonism impairs the bone marrow microenvironment and hematopoiesis

2018

Abstract Vitamin K antagonists (VKAs) have been used in 1% of the world’s population for prophylaxis or treatment of thromboembolic events for 64 years. Impairment of osteoblast function and osteoporosis has been described in patients receiving VKAs. Given the involvement of cells of the bone marrow microenvironment (BMM), such as mesenchymal stem cells (MSCs) and macrophages, as well as other factors such as the extracellular matrix for the maintenance of normal hematopoietic stem cells (HSCs), we investigated a possible effect of VKAs on hematopoiesis via the BMM. Using various transplantation and in vitro assays, we show here that VKAs alter parameters of bone physiology and reduce funct…

Cellobiose fermentation by Saccharomyces cerevisiae: Comparative analysis of intra versus extracellular sugar hydrolysis

2018

Abstract A prevalent procedure for the production of second generation bioethanol makes use of engineered yeast strains capable to hydrolyze cellobiose either in the cytosol or extracellularly. These two approaches have been compared in this study. For intracellular cellobiose hydrolysis, we initially tested three recombinant Saccharomyces cerevisiae strains that produced different cytosolic β-glucosidases and the cellodextrin transporter Po_CdtC from Penicillium oxalicum . The strain coexpressing Po_CdtC and the β-glucosidase from Neurospora crassa (NcBgl) showed the highest cellobiase activity but its growth in cellobiose was limited by sugar intake. A search of alternative cellobiose per…
