El blog y otras herramientas comunicativas de la biblioteca del Área de Gestión Sanitaria Este de Málaga - Axarquía

In 2006 the Library of the Andalusian Public Health System (BVSSPA) is constituted as a Virtual Library which provides Resources and Services that are accessed through inter-hospital local area network (corporate intranet) and Internet. On the other hand, the Hospital de la Axarquia still did not have any institutional or self-presence on the Internet and the librarian ask the need to create a space for communication with the "digital users" of the Library of the area through a website. MATERIALS AND METHODS. The reasons why we opted for a blog were: -It was necessary to make no financial outlay for its establishment. It allowed for great versatility, both in its administration and in its management by users. -The ability to compile on the same platform different Web 2.0 communication tools. Between different options available we chose Blogger Google Inc. The blog allowed entry to the 2.0 services or Social Web in the library. The benefits offered were many, especially the visibility of the service and communication with the user. 2.0 tools that have been incorporated into the library are: content syndication (RSS) which allowed users to stay informed about updates to the blog. Share documents and other multimedia as presentations through SlideShare, images through Flickr or Picasa, or videos (YouTube). And the presence on social network like Facebook and Twitter. RESULTS. The analysis of the activity we has been traking by Google Analytics tool, helping to determine the number of blog visits. Since its stablishment, on November 17th 2006, until November 29th 2010 the blog has received 15,787 visitors, 38,422 page views were consulted, at each visit on average 2.4 pages were consulted and each visit has an average stay at the site of 4'31''. DISCUSSION. The blog has served as a communication and information tool with the user. Since the creation of the blog we have incorporated technologies and tools to interact with the user. With all the tools used we have applied the concept of "open source" and the contents were generated from the activities organized in the Knowledge Management Unit from the anatomo-clinical sessions, the training activities, dissemination events, etc. The result has been the customization of library services, contextualized in the Knowledge Management Unit - Axarquia. In social networks we have shared information and files with the professionals and the community. CONCLUSIONS. The blog has allowed us to explore technologies that allow us to communicate with the user and the community, disseminate information and documents with the participation of users and become the "Interactive Library" we aspire to be.

Epiphyseal fracture of distal humerus in children, treated with bio-absorbable materials: one year follow-up

Introduction: The use of bioabsorbable materials for orthopaedic useand traumatic fracture fixation in children has been poorly investigatedin the litterature and the effects on growing bones seem contradictory.The aim of the study is to compare the clinical and radiological resultsand evolution between bioabsorbable and traditional K-Wires for thetreatment of elbow epiphyseal fractures in children.Method: From jan. 2008 to Dec. 2009 21 children with similar fracturesand age were separated in two groups according to the way of fracturefixation: bioabsorbable K-Wire group and traditional K-Wire group.Follow-up was done at 3, 6 and 12 month post-operatively. Range ofmotion and elbow stability were measured for all patients. Theradiological evolution of the two groups were compared in term ofconsolidation, ossous resorption and radiolucencies. The clinicalresults were compared according to the Mayo Elbow Peformancescore. Controlateral elbow is compared with injured elbow in the twogroups.Results: In the bioabsorbable K-wire group, there were 10 children,including 5 girles and 5 boys with an average age of 9.5 years, rangingfrom 5 to 14 years. They were 7 external condylar fractures and3 epitrochlear fractures. In the traditional K-Wire group there were11 children, 2 girls and 9 boys with an average age of 7.6 years,ranging from 4 to 14 years. There were 10 external condylar fracturesand 1 epitrochlear fracture. At first follow up. The Mayo ElbowPerformance score was 93.8 (85-100 )for the bioabsorbable K-Wiregroup and 95.5 (85-100) for the traditional K-Wire group. In twochildren from the bioabsorbable K-Wire group there were transitoryradiolucencies along the wire tract on the x-ray, without clinicalmanifestation of it.We didn't see any premature closure of growingcartilage.Discussion: There is no significant differencies in term of clinical andradiological outcome between the two groups. The use ofbioabsorbable pins seems to be a good alternative to removabletraditional materials, avoiding a second operation.

Microtubule-associated protein-2 immunoreactivity: a useful tool in the differential diagnosis of low-grade neuroepithelial tumors.

Complex and variable morphological phenotypes pose a major challenge to the histopathological classification of neuroepithelial tumors. This applies in particular for low-grade gliomas and glio-neuronal tumors. Recently, we and others have identified microtubule-associated protein-2 (MAP2) as an immunohistochemical marker expressed in the majority of glial tumors. Characteristic cell morphologies can be recognized by MAP2 immunoreactivity in different glioma entities, i.e., process sparse oligodendroglial versus densely ramified astrocytic elements. Here, we describe MAP2-immunoreactivity patterns in a large series of various neuroepithelial tumors and related neoplasms (n = 960). Immunohistochemical analysis led to the following conclusions: (1) specific pattern of MAP2-positive tumor cells can be identified in 95% of glial neoplasms; (2) ependymal tumors do not express MAP2 in their rosette-forming cell component; (3) tumors of the pineal gland as well as malignant embryonic tumors are also characterized by abundant MAP2 immunoreactivity; (4) virtually no MAP2 expression can be observed in the neoplastic glial component of glio-neuronal tumors, i.e. gangliogliomas; (5) malignant glial tumor variants (WHO grade III or IV) exhibit different and less specific MAP2 staining patterns compared to their benign counterparts (WHO grade I or II); (6) with the exception of melanomas and small cell lung cancers, MAP2 expression is very rare in metastatic and non-neuroepithelial tumors; (7) glial MAP2 expression was not detected in 56 non-neoplastic lesions. These data point towards MAP2 as valuable diagnostic tool for pattern recognition and differential diagnosis of low-grade neuroepithelial tumors.

Materials nanocomposits a partir de whiskers de cel•lulosa i matriu polimèrica de cautxú

De acuerdo con los objetivos generales del proyecto y plan de trabajo previsto, para esta anualidad, se obtuvieron fibras y microfibras de celulosa a partir de dos fuentes: celulosa vegetal de pino y eucalipto y celulosa bacterial. Las microfibrillas han sido utilizadas como material de refuerzo para la fabricación de materiales compuestos a partir de caucho natural, policaprolactona y polivinil alcohol. Las muestras se fabricaron mediante la técnica de "casting" en medio acuoso y temperatura ambiente. Las muestras fueron caracterizados en sus propiedades mecánicas, físicas y térmicas. Se observó que, en general, la adición de las microfibrillas de celulosa en las matrices poliméricas provoca una mejora sustancial en las propiedades mecánicas del material en comparación con el polímero sin reforzar. Los resultados pueden resumirse de la siguiente manera: 1.Fabricación de materiales compuestos a base de caucho natural y fibras de celulosa. Se obtuvieron fibras y nanofibras de celulosa que fueron modificadas químicamente y usadas como refuerzo en matriz de caucho. Los resultados mostraron mejora de propiedades mecánicas del material, principalmente en los materiales compuestos reforzados con nanofibras. 2. Obtención de whiskers de celulosa y su utilización como material de refuerzo en una matriz de policaprolactona. Se obtuvieron whiskers de celulosa a partir de pasta blanqueada. La adición en una matriz de policaprolactona produjo materiales compuestos con propiedades mecánicas superiores a la matriz, con buena dispersión de los whiskers. 3. Obtención de fibras de celulosa bacterial y nanofibras de celulosa, aislamiento y utilización sobre una matriz de polivinil alcohol. Se obtuvo celulosa bacterial a partir de la bacteria Gluconacetobacter xylinum. Además se fabricaron nanofibras de celulosa a partir eucalipto blanqueado. La celulosa bacterial como material de refuerzo no produjo importantes mejoras en las propiedades mecánicas de la matriz; en cambio se observaron mejoras destacables con la nanofibra como refuerzo.

Political Humor as a confrontational tool against the Syrian regime: A study case: Syria, 15th March 2011 – 15th May 2012

The aim of this working paper is to analyze the inclusion of political humor into the set of actions used by opponents to the Syrian regime during the first year of a state-wide uprising in 2011. The research argues that although political humor has traditionally been seen mainly as a concealed voice against dominant elites, it can nevertheless take a confrontational stance and challenge a regime. In this paper we assess the role of political humor in challenging the legitimacy of the Syrian State through the battle for the signification of events. We will work with a theoretical framework that draws its assumptions from social movements’ studies and cultural studies. Through the assessment of the importance of discourse and the role of ideological domination to a regime we will see how the first year of the Syrian uprising included widespread acts of political humor as part of the strategy against the regime.

Estudi del comportament de materials nanoestructurats en el tractament d'aigües contaminades amb arsènic

El SPION (Super Paramagnetic Iron Oxide Nanoparticles) ha estat estudiat com un nou adsorbent per eliminar l’arsènic d’aigües contaminades. Les condicions òptimes de treball es van assolir per un pH de 3,6 i per concentracions inferiors als 100ppm. No es van trobar interferències significatives produïdes pels cations Cu, Ni i Zn en l’adsorció de l’As, sent el fosfat l’anió que més interfereix. Una esponja de cel·lulosa s’ha utilitzat com a suport del SPION, per disminuir les agregacions de les nanopartícules en suspensió i per proporcionar una material adequat per l’adsorció en continu, experiment amb columnes. Així, es va obtenir un augment de la capacitat d’adsorció del SPION per l’As(V), mentre que per l’As(III) continua sent baixa, per tant s’augmenta la selectivitat per l’As(V). Les interferències aniòniques afecten d’igual manera a l’adsorció de l’As(III) i l’As(V) quan l’adsorció és en continu o en discontinu. Els cations metàl·lics no interfereixen en l’adsorció de l’arsènic, a excepció del coure que és adsorbit i porta a la disminució de l’adsorció d’arsènic.

Caracterització de la fibra Henequén per ser utilitzada com a reforç en materials compostos

La generació massiva de residus plàstics constitueix actualment un gravíssim problemamediambiental. Una de les estratègies desenvolupades per pal•liar-lo consisteix en el reciclatge delsresidus plàstics i la seva posterior utilització en diferents aplicacions en sectors com la construcció.La incorporació de reforços en el material reciclat millora les seves propietats mecàniques. Unpossible reforç són les fibres d'origen vegetal o biofibres, que, a més de millorar tècnicament elproducte, presenten avantatges econòmics i ambientals. Les biofibres són un bon competidor contrales fibres reforçants tradicionals com la fibra de vidre ja que presenten un baix cost, baixa densitat i,per tant, bones propietats específiques, menys equip de processament, alta suavitat,biodegradabilitat i són ecològicament sostenibles, ja que es produeixen a partir de recursos naturals.En aquest treball es fan servir fibres provinents de la pinya de Henequén. Aquestes fibres són unsubproducte del procés per a l’obtenció del licor de Henequén i es volen fer servir com a reforç enmaterials compostos.Ja s’han fet estudis sobre la fibra de Henequén que creix a Mèxic. Aquest projecte s’emmarca dinsuna col•laboració entre la Universitat de Girona i la Universitat Cubana de Holguin, per tal d’estudiarla fibra de Henequén que creix a Cuba

Lateral condyle fracture of the humerus in children treated with bioabsorbable materials.

The aim of this study was to compare clinical and radiological outcome of lateral condyle fracture of the elbow in children treated with bioabsorbable or metallic material. From January 2008 to December 2009, 16 children with similar fractures and ages were grouped according to the fixation material used. Children were seen at 3, 6, and 12 months and more than 4 years (mean 51.8 months) postoperatively. The clinical results were compared using the Mayo Elbow Performance Score (MEPS). Radiographic studies of the fractured and opposite elbow were assessed at last follow-up control. Twelve children had a sufficient followup and could be included in the study. Seven could be included in the traditional group and 5 in the bioabsorbable group. At 12 months, the MEPS was 100 for every child in both groups. Asymptomatic bony radiolucent visible tracks and heterotopic ossifications were noted in both groups. There were no significant differences in terms of clinical and radiological outcome between the two groups. The use of bioabsorbable pins or screws is a reasonable alternative to the traditional use of metallic materials for the treatment of lateral condyle fracture of the elbow in children.

A New Imaging Software To Evaluate The Centration Of Capsulorhexis And Intraocular Lens (IOL) After Cataract Surgery

Purpose: IOL centration and stability after cataract surgery is of high interest for cataract surgeons and IOL-producing companies. We present a new imaging software to evaluate the centration of the rhexis and the centration of the IOL after cataract surgery.Methods: We developed, in collaboration with the Biomedical Imaging Group (BIG), EPFL, Lausanne, a new working tool in order to assess precisely outcomes after IOL-implantation, such as ideal capsulorhexis and IOL-centration. The software is a plug-in of ImageJ, a general-purpose image processing and image-analysis package. The specifications of this software are: evaluation of the rhexis-centration and evaluation the position of the IOL in the posterior chamber. The end points are to analyze the quality of the centration of a rhexis after cataract surgery, the deformation of the rhexis with capsular bag retraction and the centration of the IOL after implantation.Results: This software delivers tools to interactively measure the distances between limbus, IOL and capsulorhexis and its changes over time. The user is invited to adjust nodes of three radial curves for the limbus, rhexis and the optic of the IOL. The radial distances of the curves are computed to evaluate the IOL implantation. The user is also able to define patterns for ideal capsulorhexis and optimal IOL-centration. We are going to present examples of calculations after cataract surgery.Conclusions: Evaluation of the centration of the rhexis and of the IOL after cataract surgery is an important end point for optimal IOL implantation after cataract surgery. Especially multifocal or accommodative lenses need a precise position in the bag with a good stability over time. This software is able to evaluate these parameters just after the surgery but also its changes over time. The results of these evaluations can lead to an optimizing of surgical procedures and materials.

Novel murine dendritic cell lines: a powerful auxiliary tool for dendritic cell research.

Research in vitro facilitates discovery, screening, and pilot experiments, often preceding research in vivo. Several technical difficulties render Dendritic Cell (DC) research particularly challenging, including the low frequency of DC in vivo, thorough isolation requirements, and the vulnerability of DC ex vivo. Critically, there is not as yet a widely accepted human or murine DC line and in vitro systems of DC research are limited. In this study, we report the generation of new murine DC lines, named MutuDC, originating from cultures of splenic CD8α conventional DC (cDC) tumors. By direct comparison to normal WT splenic cDC subsets, we describe the phenotypic and functional features of the MutuDC lines and show that they have retained all the major features of their natural counterpart in vivo, the splenic CD8α cDC. These features include expression of surface markers Clec9A, DEC205, and CD24, positive response to TLR3 and TLR9 but not TLR7 stimuli, secretion of cytokines, and chemokines upon activation, as well as cross-presentation capacity. In addition to the close resemblance to normal splenic CD8α cDC, a major advantage is the ease of derivation and maintenance of the MutuDC lines, using standard culture medium and conditions, importantly without adding supplementary growth factors or maturation-inducing stimuli to the medium. Furthermore, genetically modified MutuDC lines have been successfully obtained either by lentiviral transduction or by culture of DC tumors originating from genetically modified mice. In view of the current lack of stable and functional DC lines, these novel murine DC lines have the potential to serve as an important auxiliary tool for DC research.
