99mTc–MAG3–Nierenfunktionsszintigraphie ohne und mit Captopril zur Diagnostik der renovaskulären Hypertonie
1993
In this study, the diagnostic value of renal function scintigraphy performed both without and with ACE inhibition has been evaluated using the new radiopharmaceutical 99mTc-MAG3. In cases of decompensated renal artery stenoses, the typical scan finding with this tubular excreted agent was shown to be a distinct parenchymal nuclide retention in combination with a delayed appearance of the radiotracer in the pelvic system. Using this criterion in 43 patients with suspected renovascular hypertension, sensitivity and specificity were 89 and 88%, respectively. Bilateral positive findings were non-specific; excluding them from the study, specificity increased to 100%. In renal insufficiency, capt…
What have we learnt 50 years after the first Fontan procedure?
2020
The Fontan procedure is often the only definitive palliative surgical option for patients with a variety of complex CHD sharing in common, a single, dominant ventricle. In recent decades, imaging and therapeutic improvement have played a crucial role in those patients in whom many complications can hamper their life. After 50 years from the first procedure, heart transplantation remains the only definitive treatment for those with a failing Fontan circulation.
The Potential Use of Resveratrol for Cancer Prevention.
2019
In addition to the traditional treatments of cancer and cancer prevention, the use of natural compounds, especially those found in food, should be considered. To clarify if resveratrol has the potential for cancer prevention and the possibility of use in therapy, the following must be taken into account: data from epidemiology, clinical protocol (case and control), preclinical studies (lab animals), use of established cell lines as models of cancer cells, test tube assays (enzymes activities), and requirements of nanotechnologies in order to discover new drugs to fight cancer. From this perspective and future expected advances, more information is needed such as improved efficacy, methods o…
External knowledge sourcing for R&D activities: antecedents and implications of governance mode choice
2014
This paper investigates how internal and external factors affect the choice between alliances and joint ventures (A&JVs) and mergers and acquisitions (M&As) for the external sourcing of research and development (R&D) activities, and whether or not such a choice is really con- tingent, that is, is it the best choice in terms of its impact on firms’ innovative performance under those circumstances? We build a set of hypotheses based on both the transaction-cost theory and the resource-based view, and test them through a secondary data source analy- sis. We found that companies adopt either R&D M&A or A&JV depending on internal (e.g. resources and capabilities, innovation experience) and exter…

Factores transformadores de la educación inclusiva mediante la gamificación
2022
El mandato de los organismos internacionales en favor de la inclusión educativa y la abundante producción de literatura académica en torno a las virtudes pedagógicas de la gamificación constituyen evidencias que invitan a indagar sobre el tema. En este trabajo se analiza si la gamificación favorece entornos de aprendizaje inclusivos para alumnado que presenta necesidades específicas de apoyo educativo. La metodología adoptada en el trabajo de campo fue el estudio de caso en un centro valenciano, examinándose en los seis cursos de Educación Primaria 18 aulas con 519 estudiantes. En el procedimiento adoptado se triangulan instrumentos como son la observación, las entrevistas o los grupos de d…
The importance of social networks in the Norwegian firewood industry
2013
Accepted version of an article from journal of Biomass and Bioenergy This study examines the relationship between social network size, innovation and firm performance among firewood producers in Norway. Moreover, it investigates how this relationship is affected both by the structure and variations in networks and by firm size and age. A questionnaire-based survey was sent to managers of firms (including one-person firms) in the firewood industry in Norway. A total of 645 usable replies were received, and the theoretical model was tested using structural equation modeling. The findings show that social network size has a positive effect on firm performance via innovation by firewood produce…
