Effects of malvidin, cyanidin and delphinidin on human adipose mesenchymal stem cell differentiation into adipocytes, chondrocytes and osteocytes.
2019
Abstract Background Anthocyanidins are plant phytochemicals found at high concentrations in berries, vegetables and flowers. Anthocyanidins have been extensively investigated due to their antioxidative, antidiabetic and anti-inflammatory effects. Few studies show that anthocyanidins decrease obesity and improve bone density. However, the effects of anthocyanidins on tissue regeneration have not been sufficiently clarified. Human mesenchymal stem cells (MSCs) are multipotent adult stem cells responsible for the regeneration of fat, bone and cartilage. Although MSCs are often used for screening of biologically active compounds, so far, the effect of anthocyanidins on MSC differentiation has n…
Evaluation of thrombin generation in classical Philadelphianegative myeloproliferative neoplasms / Evaluarea generării trombinei în neoplasmele mielo…
2016
Abstract Introduction: Patients with Philadelphia-negative chronic myeloproliferative neoplasms (Ph-MPN), polycytemia vera (PV), essential thrombocythaemia (ET) and primary myelofibrosis (PMF), are prone to develop thrombotic events. We aimed to investigate the coagulation status in their plasma using thrombin generation assay (TGA), a functional global assay, on Ceveron® Alpha. Materials and methods: The samples were collected from 89 consecutive Ph-negative MPN patients and from 78 controls into K2EDTA and CTAD tubes for blood cell counts, TGA and coagulation screening tests. Thrombin generation was analysed in platelet-poor plasma using Technothrombin® TGA assay kit. Results: We found a …
mb at MZ
1998
Abstract The value of the b quark mass at the M Z scale defined in the MS renormalization scheme, m b ( M Z ), was determined using 2.8 million hadronic Z decays collected during 1992-1994 by the DELPHI detector to be m b (M Z )=2.67±0.25 ( stat. )±0.34 ( frag. )±0.27 ( theo. ) GeV/c 2 . The analysis considers NLO corrections to the three-jet production rate including mass effects, and the result obtained agrees with the QCD prediction of having a running b quark mass at an energy scale equal to M Z . This is the first time that such a measurement is performed far above the b b production threshold. The study also verifies the flavour independence of the strong coupling constant for b and l…
A questionnaire to assess parental perception of barriers towards active commuting to school (PABACS): Reliability and validity
2019
Abstract Introduction Parental barriers are a key factor to determine physical activity behaviors, such as active commuting to school in young people. The purpose of this study was to test the reliability and validity of a questionnaire which addresses parental barriers towards active commuting to school. Methods This paper describes the development, following the Delphi method, and the validation of a Likert-scale questionnaire of 23 items (Parental Perception of Barriers towards Active Commuting to School (PABACS)) designed to determine the main parental barriers. These barriers are categorized into 3 scales (general, walking, and cycling barriers) and the overall questionnaire. A total o…
The future of 'serious games' in accounting education: A Delphi study
2019
Abstract Previous literature on Serious Games (SGs) has focused on the possible impacts of these educational tools on learning effectiveness. However, the empirical evidence is still scarce, and these learning-based games are rarely used in general undergraduate courses and even less so in accounting courses compared with other business areas. Using an existing digital game and a sample of accounting lecturers, this paper uses the Delphi methodology to examine accounting academicś perceptions of the usefulness and the potential barriers to implementing SGs in the classroom. Our results show that the knowledge and funding of technology is no longer an issue. However, incentives to motivate a…
Are Cities Aware Enough? A Framework for Developing City Awareness to Climate Change
2020
Cities are growing and becoming more complex, and as they continue to do so, their capacity to deal with foreseen and unforeseen challenges derived from climate change has to adapt accordingly. In the last decade, an effort has been made to build city resilience and improve cities' capacity to respond to, recover from and adapt to climate change. However, certain city stakeholders' lack of proactive behavior has resulted in less effective city resilience-building strategies. In this sense, the importance of developing stakeholders&rsquo
Problems in the Interplay of IS Development and IT Operations: An Alignment Analysis
2013
This chapter addresses the interplay of IS development and IT operations in system development projects, as seen from the perspective of IT operations. The underlying perspective is that a well-performed interplay of the two domains is essential, both for the successful development of a new information system, as well as for its subsequent operation. In this chapter, we use alignment theory to analyse data from a Delphi study in order to investigate the interplay of the two areas. The chapter concludes that the two areas are often unsatisfactorily aligned and that improving their interplay must be a priority for IS development and IT operations alike.
A guide to indicators for the evaluation of specialist autism centres, based on the quality-of-life model
2017
Objective: The evaluation of individual and organizational quality of life through the Guide to Quality-of-Life Indicators and its promotion in English-speaking areas. This guide was initially designed for people living with Autism Spectrum Disorder in specialist autism centers in Spanish and Italian-speaking areas where its effectiveness has been validated. Method: The Delphi technique is applied to the design of a qualitative investigation, with expert validation for the adaptation to English-speaking areas. Results: The results have facilitated the adaptation and validation of the tool, which has 68 indicators grouped into six areas, for its application in both the planning and the evalu…
Design of a basic system of indicators for monitoring and evaluating Spanish Cooperation's Culture and Development Strategy.
2012
Objective: This article describes the process implemented in order to define and build up a Basic Monitoring and Evaluation System for Spanish Cooperation’s Culture and Development Strategy (CD-S). Research Design: Delphi techniques were used to assess a wide catalogue of indicators for each of the strategic areas included in the CD-S. Afterward, those indicators considered most suitable for monitoring and evaluating purposes were selected based on the assessments provided by a panel of experts. Results: As a consequence, the resulting system, made up by a total of 80 indicators, was designed to be a practical, manageable, and targeted tool for its potential users, who include managers and …
Training and guidance for entrepreneurship: what bibliometrics and novice entrepreneurs say
2019
El actual contexto socioeconómico obliga a realizar una revisión profunda del sentido del trabajo en la población. En momentos de escasez de oportunidades laborales y de redefinición del sentido y el significado del trabajo muchas personas consideran la opción del auto empleo como alternativa al desempleo y la precariedad laboral. Sin embargo, informes oficiales muestran altas tasas de abandono de los proyectos empresariales en sus primeros años. Con la intención de conocer las razones de esta situación, se centra la atención en analizar el papel que juega la orientación profesional en las fases iniciales del emprendimiento para favorecer una reflexión profunda sobre los motivos y las motiv…
