Factores personales y contextuales implicados en la motivación físico- deportiva adolescente: un estudio a partir del modelo de elección de logro

En este estudio se somete a verificación un modelo completo de regresión estructural explicativo de la actividad físico-deportiva a partir de los factores motivacionales personales y contextuales centrales del modelo de elección de logro (Eccles, 2011). Participaron en el estudio 429 adolescentes, 233 (54.30 %) hombres y 196 (45.70 %) mujeres, entre 11 y 19 años (M = 14.93; DT = 2.11) de la Comunidad Autónoma Cántabra y País Vasco. Los resultados corroboran la influencia directa de las variables expectativas de éxito y valor subjetivo de la tarea sobre la actividad físico-deportiva. Asimismo, las variables autoconcepto físico y actitudes y comportamientos de los otros significativos aparecen como predictores directos de dicho comportamiento.

TP87 153. Implantación de dos sistemas de oxigenador de membrana extracorpórea a un paciente en dos ingresos: Uno como recuperación, otro como puente a otra asistencia

IntroducciónLos programas de asistencias mecánicas de corta duración se empiezan a desarrollar en nuestro país. Uno de los más utilizados es el oxigenador de membrana extracor-pórea (ECMO), cuya mayor indicación en nuestro entorno es como puente al trasplante. Presentamos un caso en el que se coloca como recuperación, y tras 3 meses otra nueva como puente a otra asistencia.Material y métodosPaciente de 61 años que ingresa por trombosis de stent en descendente anterior (DA), presentando shock cardiogénico refractario a fármacos y balón de contrapulsación. Dada la situación se coloca ECMO venoarterial que se retira a las 72h por mejoría, dándose de alta el paciente a los 19 días.Tres meses después el paciente ingresa con bajo gasto y edema de pulmón, implantándose un ECMO venoarterial en el box de intensivos como puente a asistencia univentricular Levitronix, que se coloca 10h después en quirófano. Se reinterviene dos veces por taponamiento y se extuba a los 7 días, momento en que se incluye en alarma 0. Tras 27 días con Levitronix izquierda, la paciente sufre un ictus y retiramos de lista, falleciendo la paciente.ResultadosLos dos ECMO cumplieron su objetivo: uno de recuperación y el otro de puente a la asistencia.ConclusionesComo describimos en este caso, el ECMO es muy útil y fácil de implantar en pacientes con el objetivo de la recuperación o como puente al trasplante. Las asistencias no están exentas de complicaciones

Jugando con robots en el aula: iniciativa para incentivar el ingreso de alumnos de la escuela secundaria a carreras de Ingeniería

Este trabajo describe una iniciativa de divulgación de tecnología aplicada en Escuelas Secundarias (ES) de la ciudad de Mar del Plata y sus alrededores. El objetivo es el hacer participar a los alumnos en actividades tecnológicas que están a su alcance, es decir utilizando herramientas con las que interactúa diariamente, por ejemplo las netbooks provistas por el plan Conectar Igualdad. Se espera que estas actividades que vinculan a los alumnos secundarios con la Universidad despierten su interés en continuar con una carrera terciaria o universitaria de carácter tecnológico y fomentar en el alumnado, la toma de conciencia que el manejo aplicado de la tecnología no es algo que este fuera de su alcance. La temática, en la que se basa esta propuesta, es la robótica y la automatización que en la actualidad ha salido de un ámbito puramente industrial o de investigación y está presente en otros muy cercanos a la sociedad en general. Algunos ejemplos de esto son, las prestaciones extendidas de electrodomésticos, vehículos, sistemas de comunicaciones, etc. Desde el punto de vista didáctico y metodológico, trabajar con estos sistemas permite integrar de forma armónica, a través de pocas actividades, la mayoría de los bloques de contenidos de las materias de tecnología.Eje: Educación en TecnologíaRed de Universidades con Carreras en Informática (RedUNCI

Ammonia levels in different kinds of sampling sites in the central Iberian Peninsula

Ponencia presentada en:2nd Iberian Meeting on Aerosol Science and Technology (RICTA 2014) celebrado en Tarragona del 7 al 9 de julio de 2014.Ammonia is the Secondary Inorganic Aerosol (SIC) gaseous precursor which has been studied to a lesser extent in the Madrid Metropolitan Area up to date. A study conducted in the city of Madrid with the aim of characterizing levels of ammonia took place in 2011. These campaigns formed part of a larger study conducted in 6 Spanish cities. A time series of weekly integrated ammonia measurements available at an EMEP rural site (Campisábalos) has been used to obtain information on the ammonia rural background in the region. The results point to traffic and waste treatment plants as the main ammonia sources in Madrid. Relevant seasonal differences have not been observed in the Metropolitan Area. The explanation can be related to the fall in the rural background levels during July 2011, which might conceal urban summer emission increases observed in other cities

Long-term surveillance of the feline leukemia virus in the endangered Iberian lynx (Lynx pardinus) in Andalusia, Spain (2008-2021)

Feline leukemia virus (FeLV) infection is considered one of the most serious disease threats for the endangered Iberian lynx (Lynx pardinus) Over 14 years (2008-2021), we investigated FeLV infection using point-of-care antigen test and quantitative real-time TaqMan qPCR for provirus detection in blood and tissues in lynxes from Andalusia (Southern Spain). A total of 776 samples from 586 individuals were included in this study. The overall prevalence for FeLV antigen in blood/serum samples was 1.4% (5/360) (95% CI: 0.2-2.6), FeLV proviral DNA prevalence in blood samples was 6.2% (31/503) (95% CI: 4.1-8.6), and FeLV proviral DNA in tissues samples was 10.2% (34/333) (95% CI: 7-13.5). From a subset of 129 longitudinally sampled individuals, 9.3% (12/129) PCR-converted during the study period. Our results suggest that FeLV infection in the Andalusian population is enzootic, with circulation of the virus at low levels in almost all the sampling years. Moreover, since only one viremic individual succumbed to the infection, this study suggests that lynxes may therefore control the infection decreasing the possibility of developing a more aggressive outcome. Although our results indicate that the FeLV infection in the Iberian lynx from Andalusia tends to stay within the regressive stage, continuous FeLV surveillance is paramount to predict potential outbreaks and ensure the survival of this population

Survival and dispersal routes of head-started loggerhead sea turtle (Caretta caretta) post-hatchlings in the Mediterranean Sea

[EN] Several loggerhead sea turtle (Caretta caretta) nesting events have been recorded along Spain's Mediterranean coast, outside its known nesting range, in recent years. In view of the possible expansion of its nesting range and considering the conservation status of this species, management measures like nest protection and head-start programs have been implemented. To study the dispersal behavior and survival of head-started loggerheads, 19 post-hatchlings from three nesting events were satellite tracked after their release in three consecutive years (2015-2017). This paper presents the first study of survival probabilities and dispersal movements of loggerhead post-hatchlings in the Mediterranean basin. Monitored post-hatchlings dispersed over large areas using variable routes, mainly off the continental shelf. Nonetheless, post-hatchlings dispersed to high-productivity warmer areas during the coldest months of monitoring. These areas might be optimum for their survival and development. We observed differences regarding dispersal orientation and routes among individuals, even from the same nest, release date, and location. Our survival models contributed to improving current survival estimates for sea turtle post-hatchlings. We observed a high probability of survival in head-started individuals during the first months after release, usually the most critical period after reintroduction. The data did not support an effect of habitat (neritic or oceanic) in survival, or an effect of the region (Balearic sea or Alboran sea) in survival probability. Differences in survival between nests were observed. These differences might be related to parasitic infections suffered during the head-starting period. This study shows that nest management measures may contribute to the conservation and range expansion of the loggerhead turtle population in the western Mediterranean.This satellite study was funded by Universitat Politecnica de Valencia, Ministerio de Agricultura y Medio Ambiente (ref: 16MNSV006), Ministerio de Economia, Industria y Competitividad (ref: CGL2011-30413), Fundacion CRAM, Fundacion Hombre y Territorio and Eduardo J.

Head-to-head comparison of two engineered cardiac grafts for myocardial repair: From scaffold characterization to pre-clinical testing

Cardiac tissue engineering, which combines cells and supportive scaffolds, is an emerging treatment for restoring cardiac function after myocardial infarction (MI), although, the optimal construct remains a challenge. We developed two engineered cardiac grafts, based on decellularized scaffolds from myocardial and pericardial tissues and repopulated them with adipose tissue mesenchymal stem cells (ATMSCs). The structure, macromechanical and micromechanical scaffold properties were preserved upon the decellularization and recellularization processes, except for recellularized myocardium micromechanics that was ∼2-fold stiffer than native tissue and decellularized scaffolds. Proteome characterization of the two acellular matrices showed enrichment of matrisome proteins and major cardiac extracellular matrix components, considerably higher for the recellularized pericardium. Moreover, the pericardial scaffold demonstrated better cell penetrance and retention, as well as a bigger pore size. Both engineered cardiac grafts were further evaluated in pre-clinical MI swine models. Forty days after graft implantation, swine treated with the engineered cardiac grafts showed significant ventricular function recovery. Irrespective of the scaffold origin or cell recolonization, all scaffolds integrated with the underlying myocardium and showed signs of neovascularization and nerve sprouting. Collectively, engineered cardiac grafts -with pericardial or myocardial scaffolds- were effective in restoring cardiac function post-MI, and pericardial scaffolds showed better structural integrity and recolonization capability
