Este trabajo se basa en mostrar la capacidad que la educación física ofrece para conocerse a uno mismo a través de la expresión corporal. Para llegar a esta idea, se hace hincapié en la materia y conceptos de cuerpo, espacio, tiempo y emociones como elementos de la expresión corporal y el cuerpo creativo a través de la expresión corporal. Posteriormente, se plantea una propuesta didáctica destinada a 3º ciclo de Educación Primaria, en la que se transforman estas ideas teóricas en prácticas para que el alumnado, a través de la creatividad motriz corporal, pueda llegar a un conocimiento corporal y experimentar sus posibilidades expresivas.This work is focus on showing how physical education is able to offer knowledge of yourself trough body expression. To go further into the issue we pay attention in body, space, time and emotions concepts as a way to use body expression in a creative way. To conclude, it is designed a proposal to work in the third cycle of Primary Education. In this proposal, theorical ideas are turned into practical in order to make students be able to achieve their own body knowledge and experiment their expressive skills.Grado en Educación Primari

Effects of Chemical and Enzymatic Modifications on Starch and Naringenin Complexation

Naringenin is a flavanone naturally present in grapefruit and tomato skin, which has been demonstrated to have health benefits. However, because of the low water solubility and bioavailability, naringenin applications are limited. Starch inclusion complexes have been shown to improve the solubility and bioavailability of poorly water soluble bioactive compounds. The present study aimed to prepare and characterize complexes of naringenin with starches, including potato starch and high amylose corn starch (Hylon VII), which were chemically (acetylation or hydroxypropylation) and enzymatically modified (debranched or debrahced/β-amylase treated). Soluble and insoluble complexes were recovered, and their physicochemical properties were characterized. The treatments did not affect overall recovery, but the introduction of acetyl and hydroxypropyl groups significantly increased the recovery of soluble complexes. Overall, acetylated starches exhibited greater complexation yields than hydroxypropylated counterparts; Hylon VII complexes comprised greater naringenin contents than potato starch complexes. The naringenin content generally was greater in insoluble complexes than in soluble complexes and increased when β-amylase treatment was incorporated. The X-ray diffraction patterns of both complexes revealed a mixture of amorphous and crystalline structure. FT-IR results confirmed the occurrence of molecular interaction between starch and naringenin in both complexes. Melting properties were significantly influenced by the type and degree of substitution. The present results demonstrate that the complexation of starch with naringenin can be improved by a combination of chemical and enzymatic modifications

Starch Granule and Crystalline Structures with Relation to Enzyme Digestibility

Porous starch produced by enzyme hydrolysis has attracted much attention for its adsorption and delivery properties. Porous starch has been successfully prepared from A-type starch, but not from B-type and C-type starches, which is partly attributed to the surface and crystalline structure. The present study aimed to characterize the role of the crystalline structure and the structure-function relationship impacting the susceptibility of starch with different crystalline polymorphs to amylase digestion. The starches were subjected to chemical modification (acid hydrolysis or surface gelatinization), physical modification (heat-moisture treatment, HMT, or high-pressure processing, HPP) or their combinations prior to amylase digestion, and the physiochemical properties of the resultant starches were characterized. Both acid hydrolysis and surface gelatinization removed densely packed crystallites to improve amylase binding and the digestion degree, resulting in the formation of a porous structure in potato starch. Combined acid hydrolysis and HMT reduced the amylase digestion degree of all three starches by increasing their thermal stability and crystallinity from hydrolyzed starch chains that reorganized into more thermally stable structures. The strong electrostatic interaction of sodium sulfate with water molecules decreased the gelatinization degree during HPP, and generally decreased the α-amylase digestion degree compared to HPP in water for all three starches. However, the competition for the water in the starch crystallites and the restricted association of gelatinized starch from reduced free water in sodium sulfate allowed the formation a porous structure in corn and potato starches and their partial transition to a C-like polymorph. The results demonstrate that the combination of chemical or physical modification and alpha-amylase digestion was capable of producing porous starch from B-type starches. This study will help develop porous starch with new properties for applications in food, pharmaceutical and agricultural industries

Investigating specialized translators: Corpus and documentary sources

This paper describes research carried out through electronic surveys of three groups of translators working in different areas of expertise (legal, medical and technical) that aimed to discover their socio-professional profile, their opinions both on corpora and other documentary sources, and the use they make of them. Certain characteristic features emerged from the analysis of data on the three population groups, regarding years of experience, documentary sources used and most usual clients. For example, even if legal translators seem more satisfied with the documentary sources available, medical translators never use translation memories, and technical translators often refer to thesauri. In any event, regardless of their area of activity, most subjects feel the need for a specialized corpus combining formal, terminological-lexical, macrostructural and conceptual aspects, aswell as contextual information.That isthe reasonwhy the GENTT 3.0 Corpus is believed to meet the expectations and needs of professional translators.El presente artículo da cuenta de una investigación con encuestas electrónicas llevada a cabo con tres grupos de traductores que trabajan en distintas áreas de especialidad (legal,médica y técnica) y cuyo objetivo es descubrir distintasfacetas de su perfil socio-profesional, su opinión tanto acerca de los corpus como de otrasfuentes documentales, así como el uso que hacen de estas.El análisis de los datos ha puesto de relieve rasgos característicos en lostres grupos de población, concretamente en relación con los años de experiencia, las fuentes de documentación utilizadas y los clientes habituales. Por ejemplo, los traductores jurídicos parecen más satisfechos con las fuentes documentales disponibles; los traductores médicos no utilizan nunca las memorias de traducción, mientras que los traductores técnicos a menudo recurren a los tesauros. En cualquier caso, y con independencia del área de especialidad, la mayoría de sujetos valoraría positivamente un corpus especializado que combinara aspectos conceptuales, macro-estructurales, terminológicos y léxicos, y que incluyera asimismo información sobre el contexto. Por todo ello, creemos que el Corpus GENTT 3.0 respondería bien a las expectativas y necesidades de los traductores profesionales

Engineered MRI nanoprobes based on superparamagnetic iron oxide nanoparticles

This project aimed to engineer new T2 MRI contrast agents for cell labeling based on formulations containing monodisperse iron oxide magnetic nanoparticles (MNP) coated with natural and synthetic polymers. Monodisperse MNP capped with hydrophobic ligands were synthesized by a thermal decomposition method, and further stabilized in aqueous media with citric acid or meso-2,3-dimercaptosuccinic acid (DMSA) through a ligand exchange reaction. Hydrophilic MNP-DMSA, with optimal hydrodynamic size distribution, colloidal stability and magnetic properties, were used for further functionalization with different coating materials. A covalent coupling strategy was devised to bind the biopolymer gum Arabic (GA) onto MNPDMSA and produce an efficient contrast agent, which enhanced cellular uptake in human colorectal carcinoma cells (HCT116 cell line) compared to uncoated MNP-DMSA. A similar protocol was employed to coat MNP-DMSA with a novel biopolymer produced by a biotechnological process, the exopolysaccharide (EPS) Fucopol. Similar to MNP-DMSA-GA, MNP-DMSA-EPS improved cellular uptake in HCT116 cells compared to MNP-DMSA. However, MNP-DMSA-EPS were particularly efficient towards the neural stem/progenitor cell line ReNcell VM, for which a better iron dose-dependent MRI contrast enhancement was obtained at low iron concentrations and short incubation times. A combination of synthetic and biological coating materials was also explored in this project, to design a dynamic tumortargeting nanoprobe activated by the acidic pH of tumors. The pH-dependent affinity pair neutravidin/iminobiotin, was combined in a multilayer architecture with the synthetic polymers poy-L-lysine and poly(ethylene glycol) and yielded an efficient MRI nanoprobe with ability to distinguish cells cultured in acidic pH conditions form cells cultured in physiological pH conditions
