Semiautomatic detection of myocardial contours in order to investigate normal values of the left ventricular trabeculated mass using MRI
2015
Purpose To propose, assess, and validate a semiautomatic method allowing rapid and reproducible measurement of trabeculated and compacted left ventricular (LV) masses from cardiac magnetic resonance imaging (MRI). Materials and Methods We developed a method to automatically detect noncompacted, endocardial, and epicardial contours. Papillary muscles were segmented using semiautomatic thresholding and were included in the compacted mass. Blood was removed from trabeculae using the same threshold tool. Trabeculated, compacted masses and ratio of noncompacted to compacted (NC:C) masses were computed. Preclinical validation was performed on four transgenic mice with hypertrabeculation of the LV…
Low intensity vs. self-guided Internet-delivered psychotherapy for major depression: A multicenter, controlled, randomized study
2013
Abstract Background Major depression will become the second most important cause of disability in 2020. Computerized cognitive-behaviour therapy could be an efficacious and cost-effective option for its treatment. No studies on cost-effectiveness of low intensity vs self-guided psychotherapy has been carried out. The aim of this study is to assess the efficacy of low intensity vs self-guided psychotherapy for major depression in the Spanish health system. Methods The study is made up of 3 phases: 1.- Development of a computerized cognitive-behaviour therapy for depression tailored to Spanish health system. 2.- Multicenter controlled, randomized study: A sample (N=450 patients) with mild/mod…
Research on Spectroscopy in Morocco from 1984 to 2006
2007
Abstract The evolution of spectroscopy‐based research activity in Morocco was evaluated on the basis of publications that have appeared in the Science Citation Index, Expanded (SCI), during the cumulative period 1984–2006 (September). The most active research groups, and their universities or centers, were identified in this subject from their scientific production in the first years of this century. The preference to publish in specific journals, the main areas of interest to Moroccan authors, and the spectroscopy techniques most commonly employed for their studies were also appraised. This scientometric study was undertaken to introduce a group of papers in a special issue of Spectroscopy…
Conformational Isomerism in Drug Action: Does the Free Energy of Binding Induce the Pharmacophoric Conformation of Semi-Rigid Muscarinic Agonists?
1974
The physiological neurotransmitter Acetylcholine has been shown to have great molecular flexibility, and because of this, the possibility of forming numerous energetically different conformations. This property makes the determination of the biologically active conformation extremely complicated. In attempts to solve this problem various research groups have tried two basically different approaches: (1) (1) The determination of the energetically most stable conformation using crystallographic methods (X-ray diffraction studies), nuclear magnetic resonance and quantum-mechanical calculations [1–16]. Same workers hypothesized that the energetically most favourable form was also the biological…
La colaboración científica en el campo de las ciencias de la actividad física y el deporte en España
2010
Este estudio examina la colaboración científica a través de los patrones de coautoría en una muestra de revistas españolas de Ciencias de la Actividad Física y el Deporte (CCAFD). También analiza los principales grupos de investigación y disciplinas del campo multidisciplinar de las CCAFD. Se analizaron la frecuencia y porcentaje de los artículos en colaboración y el número de autores por artículo. Se revisaron las redes de colaboración de los autores más productivos para identificar grupos de investigación y se calculó la densidad para conocer su cohesión. La producción científica fue analizada también por disciplinas. Los artículos en colaboración superan a los artículos de autor único en…
Ethical challenges in care for older patients who resist help
2014
Background: Situations where patients resist necessary help can be professionally and ethically challenging for health professionals, and the risk of paternalism, abuse and coercion are present. Research question: The purpose of this study was to examine ethical challenges in situations where the patient resists healthcare. Research design: The method used was clinical application research. Academic staff and clinical co-researchers collaborated in a hermeneutical process to shed light on situations and create a basis for new action. Participants and research context: Four research groups were established. Each group consisted of six to eight clinical co-researchers, all employees with diff…
The ALHAMBRA survey: tight dependence of the optical mass-to-light ratio on galaxy colour up to z = 1.5
2018
[Aims] Our goal is to characterise the dependence of the optical mass-to-light ratio on galaxy colour up to z = 1.5, expanding the redshift range explored in previous work. [Methods] From the redshifts, stellar masses, and rest-frame luminosities of the ALHAMBRA multi-filter survey, we derive the mass-to-light ratio versus colour relation for quiescent and for star-forming galaxies. The intrinsic relation and its physical dispersion are derived with a Bayesian inference model. [Results] The rest-frame i-band mass-to-light ratio of quiescent and star-forming galaxies presents a tight correlation with the rest-frame (g - i) colour up to z = 1.5. The mass-to-light ratio versus colour relation …

Scientific literature analysis of Judo in Web of Science®
2013
Background & Study Aim: Although judo is a sport with great tradition that is practised worldwide, the state of the art and scientific advances have not been analysed from a bibliometric point of view up to now. The aim of the present article is the status of the scientific production, collaboration, and impact of scientific papers on judo, as well as the most active research groups working on this topic. Material & Methods: Our analysis was based on documents retrieved from the Science Citation Index and Social Science Citation Index. Bibliometric analysis and network construction were performed using Histcite and Bibexcel software. Results: As a result, 383 original papers and scientific …
Oilseed treatment by ultrasounds and microwaves to improve oil yield and quality: An overview.
2016
International audience; Efficiency is a key point to ensure the profitability in the production of vegetable oils from oilseeds. To maximize the recovery yields of seed oils, the traditional process involves mechanical expression followed by subsequent chemical extraction using organic solvents (e.g. hexane). Besides health, environmental, and economic related issues to the use of organic solvents, thermal treatment of seeds during conventional oil extraction process inevitably leads to chemical changes (e.g. changes in macronutrients such as protein denaturation/degradation in the meal, oil oxidation, and changes in minor constituents such as fatty acids, sterols, phenolic compounds and to…
