A comparative study of the sealing ability of two root canal obturation techniques
1995
A comparison was made of the ability of two root canal obturating techniques to prevent dye microleakage: gutta-percha lateral condensation and mechanically plasticized gutta-percha (JS Quick-fill). Twenty central incisors were prepared and obturated by each technique. After rendering the teeth transparent, linear dye penetration was found to be 0.48 and 0.52 mm, respectively. The difference between the two techniques was not significant. As for the distribution of the sealing cement (AH26) in the teeth obturated with JS Quickfill, the cement was located in the most peripheral zone of the obturation alongside the dentinal walls, whereas the gutta-percha was found in the central part of the …
Condylar position indicator and T-scan system II in clinical evaluation of temporomandibular intracapsular disease.
2012
The pathogenesis of temporomandibular joint intracapsular disease (TMJI) is multifactorial and its diagnosis is not easy. In this work authors show two types of clinical analysis: the Condylar Position Indicator (CPI) and T-Scan 2 system.Twenty patients (mean age of 24.5 years) with TMJI problem and 10 healthy matched subjects (mean age: 25.4 years) were selected. Analysis of TMJI was performed on each patient by means of Condylar Position Indicator (CPI) and T-Scan System II tests.Eight patients presented vertical symmetrical condylar distraction greater than healthy subjects (P-value0.001). T-Scan showed a difference of Percentage of Force (POF) not greater than 5%. Seven patients showed …
A prospective evaluation of zirconia anterior partial fixed dental prostheses: Clinical results after seven years.
2014
Abstract Statement of problem Because of the high mechanical strength of zirconium dioxide, the metal in fixed partial prostheses can now be replaced. However, the material is susceptible to aging or hydrothermal degradation and to chipping of the feldspathic veneer. Purpose The purpose of this prospective study was to evaluate the survival (without failure) and success (survival without any complication or failure) rate and clinical efficacy of anterior zirconia partial fixed dental prostheses. Material and methods Twenty-seven anterior partial fixed dental prostheses of 3 to 6 units were fabricated. All participants were examined after 1 month and 6 months, then annually for 7 years. Resu…
Teacher ability evaluation and changes in elementary student profiles of motivation and performance in mathematics
2018
Abstract The aim of this person-centered study is to identify the profiles of interest value, self-concept, and performance in the domain of mathematics among elementary school students and to examine the stability and changes in these profiles from grade 1 to grade 2. Teacher-reported evaluations of students' mathematical ability and gender were examined as predictors of changes in the student profiles. The sample consisted of 237 students (46.8% girls). The latent profile analysis identified four profiles: 1) low levels of interest value, medium levels of self-concept and performance; 2) low levels of interest value, self-concept and performance; 3) high levels of interest value, self-con…
Impacto de la Ley de la Dependencia en los Servicios Sociales Generales
2011
Todas las personas en situación de dependencia son usuarias de los servicios sociales, pero no todos los usuarios/as de los servicios sociales son personas en situación de dependencia. Para avanzar en la consolidación del cuarto Pilar del Estado de Bienestar Social es preciso la aplicación de la Ley de promoción de la autonomía personal y atención a las personas en situación de dependencia a la vez de elaborar nuevas Leyes de servicios sociales que formulen nuevos derechos subjetivos 'que puedan ser reclamados administrativa y jurídicamente' y ordenen racionalmente el sector, definiendo un sistema integrado. Detrás de todas las cifras hay PERSONAS con derecho a una mayor autonomía y atenció…
Radicalization in Correctional Systems: A Scoping Review of the Literature Evaluating the Effectiveness of Preventing and Countering Interventions
2023
Although several prevention and countering radicalization programs in correctional institutions have been carried out in Europe and worldwide, little is known about their effectiveness. Thus, the current scoping review aimed at reporting on the state of the art of the literature assessing and evaluating such actions, identifying knowledge gaps, and examining methods used to assess their successfulness and impact. A total of eight studies that met eligibility criteria were reviewed after performing a search on Scopus, Web of Science, and PsychInfo (Ebsco) databases: Two studies evaluated a reintegration initiative based in the Netherlands; four focused on an Australian disengagement program;…
<strong>In Silico Repurposing, Design, Synthesis and Biological Evaluation of Bisacodyl Analogues</strong>
2018
In a recent article was described in silico repositioning, design, synthesis, biological evaluation and structure-activity relationship (SAR) of an original class of anti-inflammatory agents based on a polyaromatic pharmacophore structurally related to bisacodyl (BSL) drug used in therapeutic as laxative.
Derivatization of tertiary amphetamines with 9-fluorenylmethyl chloroformate for liquid chromatography: determination of N-methylephedrine.
2000
The fluorogenic reagent 9-fluorenylmethyl chloroformate (FMOC) was evaluated for the derivatization of tertiary amphetamines prior to liquid chromatographic analysis. Conditions for the derivatization were investigated, including the reaction time, the derivatization reagent concentration and the pH, using N-methylephedrine as a model compound. On the basis of these studies, a method for the quantification of N-methylephedrine is presented. The method involves derivatization with FMOC at ambient temperature and separation of the derivatives formed on a LiChrospher C18, 5 μm, 125 × 4 mm id column using acetonitrile–water gradient elution. The proposed procedure shows good linearity, accuracy…
Reflexiones sobre cómo evaluar y mejorar la respuesta a la pandemia de COVID-19
2020
La pandemia de COVID-19 ha afectado de manera particularmente intensa a España, pese a su nivel de desarrollo y la elogiada solidez de su Sistema Nacional de Salud. Para comprender qué ha pasado e identificar cómo mejorar la respuesta creemos imprescindible una evaluación independiente multidisciplinaria de la esfera sanitaria, política y socioeconómica. En este trabajo proponemos objetivos, principios, metodología y dimensiones a evaluar, además de esbozar el tipo de resultados y conclusiones esperadas. Nos inspiramos en los requerimientos formulados por el panel independiente de la Organización Mundial de la Salud y en las experiencias evaluativas en otros países, y detallamos la propuest…
The Devaluation of Culture and the Devaluation of Education— Problem analysis on the example of selected issues from the humanities and social scienc…
2021
Increasingly, the level of education obtained in European society is related to the level of knowledge about culture and the use of culture itself. At the same time, it is alleged that higher education is now a “commodity” too easily available on the public service markets. In the opinion of some, this reduces the importance of having higher education, but also the state of science itself. The purpose of the article is to show that concepts such as “culture,” “humanities” and “education” are closely related, and therefore, an attempt to lower the meaning of one of these concepts may entail the devaluation of another concept.
