Accuracy of fit of implant-supported bars fabricated on definitive casts made by different dental stones

2018

Background The purpose of this study was to evaluate the accuracy of fitting of an implant supported screw-retained bar made on definitive casts produced by 4 different dental stone products. Material and Methods The dental stones tested were QuickRock (Protechno), FujiRock (GC), Jade Stone (Whip Mix) and Moldasynt (Heraeus). Three external hexagon implants were placed in a polyoxymethylene block. Definitive impressions were made using monophase high viscosity polyvinylsiloxane in combination with custom trays. Then, definitive models from the different types of dental stones were fabricated. Three castable cylinders with a machined non-enganging base were cast and connected with a very sma…

The significance of the order of impregnation on the activity of vanadia promoted palladium-alumina catalysts for propane total oxidation

2011

The increased activity of alumina-supported palladium catalysts promoted with vanadium oxide has been investigated. Three different vanadium promoted Pd/Al2O3 catalysts with the same composition but synthesized employing sequential and co-impregnation were tested for the total oxidation of propane. The order of impregnation was critical to produce high activity catalysts. Vanadium and palladium co-impregnation on the Al2O3 support led to the most active catalyst, whereas the step-wise impregnated catalysts show a catalytic performance similar to or slightly better than unpromoted palladium catalysts. The high activity of the co-impregnated catalysts is related to the particle size and oxida…

Optimizing the clinical utility of PCA3 to diagnose prostate cancer in initial prostate biopsy.

2015

Background: PCA3 has been included in a nomogram outperforming previous clinical models for the prediction of any prostate cancer (PCa) and high grade PCa (HGPCa) at the initial prostate biopsy (IBx). Our objective is to validate such IBx-specific PCA3-based nomogram. We also aim to optimize the use of this nomogram in clinical practice through the definition of risk groups. Methods: Independent external validation. Clinical and biopsy data from a contemporary cohort of 401 men with the same inclusion criteria to those used to build up the reference’s nomogram in IBx. The predictive value of the nomogram was assessed by means of calibration curves and discrimination ability through the area…

An siRNA-based functional genomics screen for the identification of regulators of ciliogenesis and ciliopathy genes

2015

Item does not contain fulltext Defects in primary cilium biogenesis underlie the ciliopathies, a growing group of genetic disorders. We describe a whole-genome siRNA-based reverse genetics screen for defects in biogenesis and/or maintenance of the primary cilium, obtaining a global resource. We identify 112 candidate ciliogenesis and ciliopathy genes, including 44 components of the ubiquitin-proteasome system, 12 G-protein-coupled receptors, and 3 pre-mRNA processing factors (PRPF6, PRPF8 and PRPF31) mutated in autosomal dominant retinitis pigmentosa. The PRPFs localize to the connecting cilium, and PRPF8- and PRPF31-mutated cells have ciliary defects. Combining the screen with exome sequen…

Growth of Palladium Clusters on a Boron Nitride Nanotube Support

2015

We demonstrated that the migration process of a single palladium atom on the BNNT is not highly energy demanding and can be represented as a hopping mechanism between boron and nitrogen. A model was finally found for the interpretation of the growth energetics, showing that the process is generally favoured increasing the cluster size.

Support for families of patients dying with dementia: A qualitative analysis of bereaved family members' experiences and suggestions

2014

AbstractObjective:To explore and document the needs of family caregivers of patients dying with dementia and to identify how healthcare professionals can adequately support them.Method:We employed a cross-sectional survey containing open-ended questions that were analyzed using qualitative methods.Results:Receiving information about the diagnosis and disease trajectory of dementia is essential for the caregiving families of people dying with the disease. However, at present the communication of information offered by professionals is not experienced as satisfying. Further aspects that require improvement concern issues related to time constraints, as well as practical and emotional support …

Autonomy and Connectedness among Italian Emerging Adults: Their Relations with Psychological Well-Being

2012

Emerging adulthood is a distinct period demographically, subjectively, and in terms of identity explorations characterized by profound role changes across multiple life domains (Arnett, 2001). According to many authors (Aquilino, 2006; Fingerman, 2000), autonomy and relatedness both must be fulfilled for psychological growth and well-being not only during adolescence, but may be even more necessary as an adolescent makes the transition into emerging adulthood and then into adulthood. In this perspective, the autonomous-relational self is suggested to be a healthy synthesis of autonomy and relatedness (Kagitcibasi, 1996, 2007). Given that issues of autonomy and connectedness appear to be maj…

PERCEIVED SCHOOL CLIMATE, PARENTAL MONITORING AND CYBERBULLYING AMONG ADOLESCENTS

2020

The aim of this research was to find out the connection between the perceived school climate, parental monitoring and cyberbullying among adolescents, and whether there were differences in these variables between two adolescent age groups. It was examined how the dimensions of the perceived school climate and parental monitoring explain the adolescents’ experience of cyber victims and cyberbullies.  A total of 309 Latvian students from grades 5 to 12 (200 respondents from grades 5-9 and 109 respondents from grades 10-12) participated in the research. In data collection Parental Monitoring Scale (Stattin & Kerr, 2000), Georgia School Climate Survey (La Salle, McIntosh, & Eliasson, 20…

Perfiles de familias con factores de riesgo y problemas comportamentales en niños con déficit de atención con hiperactividad

2019

Introducción. La literatura evidencia que las familias de niños con déficit de atención e hiperactividad (TDAH) experimentan factores de riesgo relacionados con niveles elevados de estrés, menor apoyo social, o menor capacidad de afrontamiento. Estos factores familiares contextuales pueden verse agravados por la presencia de problemas comportamentales y sociales en niños con TDAH. Objetivos. El presente estudio se planteó los siguientes objetivos: 1) Identificar perfiles de familias de niños con TDAH en edad escolar de acuerdo con indicadores contextuales y variables socioemocionales como el nivel de estrés, las estrategias de afrontamiento y el apoyo social. 2) Evaluar las diferencias entr…
