CD6 has recently been identified and validated as risk gene for multiple sclerosis (MS), based on the association of a single nucleotide polymorphism (SNP), rs17824933, located in intron 1. CD6 is a cell surface scavenger receptor involved in T-cell activation and proliferation, as well as in thymocyte differentiation. In this study, we performed a haptag SNP screen of the CD6 gene locus using a total of thirteen tagging SNPs, of which three were non-synonymous SNPs, and replicated the recently reported GWAS SNP rs650258 in a Spanish-Basque collection of 814 controls and 823 cases. Validation of the six most strongly associated SNPs was performed in an independent collection of 2265 MS patients and 2600 healthy controls. We identified association of haplotypes composed of two non-synonymous SNPs [rs11230563 (R225W) and rs2074225 (A257V)] in the 2nd SRCR domain with susceptibility to MS (Pmax(T) permutation=161024). The effect of these haplotypes on CD6 surface expression and cytokine secretion was also tested. The analysis showed significantly different CD6 expression patterns in the distinct cell subsets, i.e. – CD4+ naı¨ve cells, P = 0.0001; CD8+ naı¨ve cells, P,0.0001; CD4+ and CD8+ central memory cells, P = 0.01 and 0.05, respectively; and natural killer T (NKT) cells, P = 0.02; with the protective haplotype (RA) showing higher expression of CD6. However, no significant changes were observed in natural killer (NK) cells, effector memory and terminally differentiated effector memory T cells. Our findings reveal that this new MS-associated CD6 risk haplotype significantly modifies expression of CD6 on CD4+ and CD8+ T cells.

FeNi/FeMn bilayers were grown in a magnetic field and subjected to heat treatments at temperatures of 50 to 350 degrees C in vacuum or in a gas mixture containing oxygen. In the as-deposited state, the hysteresis loop of 30 nm FeNi layer was shifted. Low temperature annealing leads to a decrease of the exchange bias field. Heat treatments at higher temperatures in gas mixture result in partial oxidation of 20 nm thick FeMn layer leading to a nonlinear dependence of coercivity and a switching field of FeNi layer on annealing temperature. The maximum of coercivity and switching field were observed after annealing at 300 degrees C.

Nanostructured FeNi-based multilayers are very suitable for use as magnetic sensors using the giant magneto-impedance effect. New fields of application can be opened with these materials deposited onto flexible substrates. In this work, we compare the performance of samples prepared onto a rigid glass substrate and onto a cyclo olefin copolymer flexible one. Although a significant reduction of the field sensitivity is found due to the increased effect of the stresses generated during preparation, the results are still satisfactory for use as magnetic field sensors in special applications. Moreover, we take advantage of the flexible nature of the substrate to evaluate the pressure dependence of the giant magneto-impedance effect. Sensitivities up to 1 Omega/Pa are found for pressures in the range of 0 to 1 Pa, demostrating the suitability of these nanostructured materials deposited onto flexible substrates to build sensitive pressure sensors.

Jakin dakigunez, Heziketa Fisikoko irakasle moduan gure helburua ikasleen garapen integrala ematea da. Horretarako, prestatu eta proposatu beharreko edukiak ahalik eta osatuagoak lantzea ezinbestekoa bilakatzen da. Lan horretan, jakina da saio bakoitzean planteatutako ekintza edo jarduera guztiak jokaera motorrak osatutako aspektuak jaso edo landu behar direla. Ekintza hauek, arlo biologikoa, arlo emozionala, harremanen arloa eta arlo kognitiboa barneratzen dituelarik. Lan hau aurrera eramateko orduan, aldiz, arlo emozionalean oinarritu naiz, ikerketaren norabidea alderdi honetara bideratuz . Izan ere, lan honen bitartez alderdi emozionalari garrantzia emateaz gain, Heziketa Fisikoan duen garrantzia azpimarratzen da. Bertan, egoera motor bakoitzean (Psikomotoreak ala soziomotoreak; eta soziomotorretan aurkaritzakoak, lankidetzakoak eta, lankidetza-aurkaritzakoak) ematen diren emozio positiboak ikertzen dira. Ikerketa hau, Bilbon, Irala auzoko Gallego Gorria eskolako bosgarren eta seigarren mailako ikasleei bideratu zaie. Guztira 64 ikaslek parte hartu dute. Ikerketako datuak jasotzeko prozedura ez da metodologia batean oinarritu, baizik eta metodologia kualitatiboaren zein kuantitatiboaren bitartez bideratu da. Horrela, ikerketa ezberdinak burutu eta emaitzak interpretatu ostean datu batzuk jaso ditut: Heziketa Fisikoak emozio positiboak eragiten dizkio ikasleei, jolas soziomotoreen eta psikomotoreen artean, emozio positiboak jolas soziomotorretan ematen direla, eta hauen barnean ematen diren esperientzia ezberdinetatik, ikasleek aurkaritzalankidetza jolasetan biltzen dituztela emozio positiboak.

En los últimos años la telefonía móvil ha experimentado un enorme crecimiento, siendo la plataforma Android la más extendida con una cuota de mercado claramente superior a la de sus competidores. El objetivo de este proyecto es la de explorar las posibilidades que ofrece esta plataforma para el desarrollo de aplicaciones para móviles mediante la implementación de la herramienta Empresómetro. Otro objetivo no menos importante es la de gestionar un proyecto con un cliente real, acordando funcionalidades y plazos para la construcción de la herramienta. En el presente documento se detallan todas los pasos realizados para lograr el objetivo, desde el nacimiento de la idea, hasta su desarrollo, pasando por las fases previas de captura de requisitos, análisis, diseño e implementación.
