Double-application of platelet-rich plasma on bone healing in rabbits
2010
Objective: Platelet-rich plasma (PRP) is considered to enhance bone formation especially at early stages of wound healing, depending on the limited and short life-span of platelets and growth factors. The aim of this study was to evaluate efficacy of double-application of PRP (DA-PRP) on bone healing in a rabbit calvarial defect model. Study design: Twenty-eight rabbits, each had two surgically prepared calvarial bone defects (10mm diameter), were included in this study and randomly divided into six groups. Defects (n=56) were treated with single-application of PRP (SA-PRP)(n=10), SA-PRP and beta-tricalciumphosphate (SA-PRP+TCP)(n=10), DA-PRP (n=8), DA-PRP and beta-tricalciumphosphate (DA-P…
Stearoyl-CoA desaturase 1 coding sequences abd antisense RNA affect lipid secretion in transfected chicken LMH hepatoma cells
2000
Hepatic stearoyl CoA desaturase (SCD) activity in chickens from a fat line is higher than that of chickens from a lean line and correlates with plasma triacylglycerol concentrations. Furthermore, in these lines, the hepatic SCD1 mRNA level is positively correlated with the adipose tissue weight. To analyze the contribution of the SCD1 gene in the regulation of adiposity in the early stages of triacylglycerol secretion, SCD1 coding sequence and antisense RNA expression vectors were transfected in LMH cells. After selection, these cells were analyzed with regard to SCD1 expression and lipid secretion. The amounts of secreted triacylglycerols and phospholipids were shown to be higher in LMH ce…
Reading changes in children and adolescents with dyslexia after transcranial direct current stimulation.
2016
Noninvasive brain stimulation offers the possibility to induce changes in cortical excitability and it is an interesting option as a remediation tool for the treatment of developmental disorders. This study aimed to investigate the effect of transcranial direct current stimulation (tDCS) on reading and reading-related skills of children and adolescents with dyslexia. Nineteen children and adolescents with dyslexia performed different reading and reading-related tasks (word, nonword, and text reading; lexical decision; phonemic blending; verbal working memory; rapid automatized naming) in a baseline condition without tDCS and after 20 min of exposure to three different tDCS conditions: left …
ATLAS Inner Detector alignment and analysis of the Wtb vertex structure with single top quarks
2018
Esta tesis puede ser dividida en dos partes diferentes: La primera trata sobre el alineamiento del detector interno de ATLAS, y la segunda sobre el estudio de la estructura del vértice Wtb mediante el uso de quarks top producidos en solitario. La primera parte presenta las técnicas utilizadas para alinear el detector interno de ATLAS, así como las mejoras implementadas en algoritmo de alineamiento durante el Run-II del LHC. Durante la toma de datos, tienen lugar en el detector interno diversos movimientos y deformaciones dinámicos que comprometen la calidad de los datos recogidos. Los dos más relevantes son un movimiento vertical del detector de Píxeles, y el combado del IBL. En el alineami…
L'ús d'experiments com a mètode d'aprenentatge actiu en cursos d'iniciació a l'Economia: una experiència
2012
Aquest treball presenta una experiència docent de l'ús d'experiments com a mètode d'aprenentatge actiu i facilita la seva implementació en oferir materials de suport al llibre de Bergstrom i Miller (2008). Partint de l'experiment sobre un mercat perfectament competitiu, s'han elaborat (i) una presentació en Power Point amb les instruccions, (ii) un programa en Excel que confereix al professor ple control sobre l'activitat i permet realitzar l'experiment, presentar els resultats i explicar la teoria corresponent en una única classe i (iii) una sèrie d'exercicis avaluables perquè els alumnes afermin a casa les competències i habilitats apreses experimentant
Estudio del remodelado eléctrico cardiaco producido en un modelo experimental de síndrome metabólico y su implicación en la génesis de arritmias
2023
El síndrome metabólico (SM) afecta a aproximadamente un cuarto de la población en los países industrializados y a más del 40% de la población de 50 o más años, habiéndose convertido en los últimos años en una de las principales preocupaciones para la Salud Pública debido a su relación con la enfermedad cardiovascular. Se trata de una entidad nosológica frecuente y compleja, que representa un conjunto de alteraciones cardiovasculares y metabólicas como la obesidad, la hipertensión, la hiperglucemia, unos niveles elevados de triglicéridos y una reducción de las lipoproteínas de alta densidad (HDL). El impacto y los riesgos adversos en el sistema cardiovascular aumentan en consonancia con el n…

Computer Modeling in Philosophy of Religion
2019
AbstractHow might philosophy of religion be impacted by developments in computational modeling and social simulation? After briefly describing some of the content and context biases that have shaped traditional philosophy of religion, this article provides examples of computational models that illustrate the explanatory power of conceptually clear and empirically validated causal architectures informed by the bio-cultural sciences. It also outlines some of the material implications of these developments for broader metaphysical and metaethical discussions in philosophy. Computer modeling and simulation can contribute to the reformation of the philosophy of religion in at least three ways: b…
“She is where I’d want to be in my career” : Youth athletes’ role models and their implications for career and identity construction
2019
Abstract Objectives While role models have been documented to play a vital role in adolescents’ career development and identity exploration, in sport psychology they remain an untapped resource. The present study drew on narrative inquiry to explore the patterns of role model selection by adolescent student-athletes and the narrative maps these role models provide for self-construction. As a second objective, the study sought to understand the impact of gender on the selection and meaning of role models. Method Eighteen Finnish student-athletes (10 women, eight men) aged 17-18 participated in conversational interviews. We analysed the data with thematic and structural narrative analyses. Re…
