La colaboración interinstitucional en la producción científica española en Enfermería: análisis de redes sociales
2013
[EN]: [Objective]: The objectives of this paper are to analyze the Spanish scientific production in nursing, define its temporal evolution, its geographical and institutional distribution, and observe the interinstitutional collaboration. [Method]: We analyze a comprehensive sample of Spanish scientific production in the nursing area extracted from the multidisciplinary database SciVerse Scopus. [Results]: The nursing scientific production grows along time. The collaboration rate is 3.7 authors per paper and 61% of the authors only publish one paper. Barcelona and Madrid are the provinces with highest number of authors. Most belong to the hospitalary environment, followed closely by authors…
La universidad en el desarrollo de la cirugía torácica española
2005
The present article analyzes the figures of the university professors who, from 1911, formed part of one of the basic pillars in the development of "Spanish Thoracic Surgery". At that time, there was a certain amount of infighting between general and specialized surgery, which was resolved by allowing specialization after a period of training in general surgery. Universities should not be denied the great merit of having produced well-trained surgeons with a broad general foundation who would later choose a specialty. The figures of Ricardo Lozano Monzon, Francisco Martin Lagos, Jose Gasco, Benjamin Narbona, Carlos Carbonell Antoli, Rafael Vara Lopez, Alfonso de la Fuente Chaos and Jose M. …
Evaluation of antioxidant properties and assessment of genetic diversity of Capparis spinosa cultivated in Pantelleria Island.
2017
Capparis spinosa is a wild and cultivated bush, which grows mainly in the Mediterranean Basin. Unopened flower buds, called capers are used in the Mediterranean cuisine as flavoring for meat, vegetable and other foods. Several studies evaluated bioactive component and antioxidant activity of Capparis spinosa, increasing the market demand and the economic importance of capers.The aim of this work was to evaluate the contents of bioactive compounds in floral buds fermented in salt of C. spinosa collected from different areas of Pantelleria Island (Italy), testing the effect on healthy function as total antioxidant compounds. Hydrophilic extracts of C. spinosa from Pantelleria Island were char…
Non-small cell lung cancer (NSCLC), EGFR downstream pathway activation and TKI targeted therapies sensitivity: Effect of the plasma membrane-associat…
2017
Adenocarcinoma of Non-Small Cell Lung Cancer (NSCLC) is a severe disease. Patients carrying EGFR mutations may benefit from EGFR targeted therapies (e.g.: gefitinib). Recently, it has been shown that sialidase NEU3 directly interacts and regulates EGFR. In this work, we investigate the effect of sialidase NEU3 overexpression on EGFR pathways activation and EGFR targeted therapies sensitivity, in a series of lung cancer cell lines. NEU3 overexpression, forced after transfection, does not affect NSCLC cell viability. We demonstrate that NEU3 overexpression stimulates the ERK pathway but this activation is completely abolished by gefitinib treatment. The Akt pathway is also hyper-activated upo…
Caracterización, Inventariación y aplicación del método de Valoración Biogeográfica de paisajes vegetales (LANBIOEVA) a la comarca de Collsacabra (Gi…
2018
The study presented in this paper takes part of a research project (LANBIOEVA: Landscape Biogeographic Evaluation) carried out for the past 25 years and it is, for now, its last stage. It’s a global landscape valuation method focused on vegetation as a main element of different units that can be evaluated. So far, the use of this method has resulted in numerous works: books, articles, book chapters, communications and presentations, and it has been applied in the study of different temperate and boreal regions of Europe and America. The method has been applied in the study and assessment of diverse vegetation landscapes of the Collsacabra shire (Girona). The objective is to verify its effec…
Structural and functional genomics of symbiotic arbuscular mycorrhizal fungi.
2004
The absorbing organs (roots, rhizomes) of nearly all terrestrial plant families host an intimate symbiotic association, called a mycorrhiza, with specialized functional groups of soil fungi. The most common type of root symbiosis is the arbuscular mycorrhiza where soil fungi interact with a tremendous diversity of plant species, including many forest trees and agricultural, horticultural, and fruit crops (Gianinazzi et al., 2002). The fungi involved are very ancient microorganisms compared to other true fungi. Fossil data and molecular phylogenetic analyses indicate that their origin dates back to the Ordovician-Devonian era some 460 to 400 million years ago (Remy et al., 1994; Redecker et …
Two new triterpenoid saponins fromPittosporum senaciaPutterlick (Pittosporaceae)
2012
From the branches of Pittosporum senacia Putterlick (Pittosporaceae), two new triterpenoid saponins, senaciapittosides A and B (1, 2), were isolated. Their structures were elucidated by extensive analysis of one- and two-dimensional nuclear magnetic resonance spectroscopy, high-resolution electrospray ionization mass spectrometry (HR-ESIMS) and chemical evidence as 3-O-[β-d-glucopyranosyl-(1 2)]-[α-l-arabinopyranosyl-(1 3)]-[α-l-arabinofuranosyl-(1 4)]-β-d-glucuronopyranosyl oleanolic acid 28-O-β-d-glucopyranosyl ester (1) and 3-O-[β-d-glucopyranosyl-(1 2)]-[α-l-arabinopyranosyl-(1 3)]-[α-l-arabinofuranosyl-(1 4)]-β-d-glucuronopyranosyl-22-O-α-l-arabinopyranosyl-21-acetoxy R1-barrigen…
L'arte mantica alla prova dello scetticismo nell'Edipo re
2022
Since the beginning of the Sophoclean drama OT, King Oedipus, in his attempt to contrast the plague that afflicts Thebes, has to confront the traditional influence of the Delphic oracles and the opinion of the local seer, Tiresias, who is demanding to interpret the words of the God Apollo. In this sense, the Sophoclean drama seems to set into the Attic scene the main traits of its contemporary public debate (second half of the 5th Century BC) about power and fallibility of both oracles and their human interpreters, the so-called manteis. This paper aims by means of a detailed analysis of the dramatic discourse to investigate the positions expressed by the different characters involved in th…
Digital Storytelling Project as a Way to Engage Students in Twenty-First Century Skills Learning
2020
[EN] This paper is focused on the implications of a collaborative digital storytelling project on student engagement in the higher education context. The empirical study is conducted with an interdisciplinary group of bachelor students in a Nordic University (N = 22) and a university in Southern Europe (N = 21), and the data are collected through an online student survey. The results demonstrate that the digital storytelling project supported students’ behavioral, emotional, and cognitive engagement. In general, the students had positive emotional experiences with the project. This assignment format was found less stressful than a frontal presentation in the classroom, allowing the students…
Morphometrische Untersuchungen an Darminterponaten nach totaler Gastrektomie
1982
Im Tierexperiment wurden nach totaler Gastrektomie die Bildung eines Ersatzmagens mit verschiedenen Darminterponaten sowie der Oesophago-Jejunostomie mit Roux-Y-Anastomose durchgefuhrt. Bei der Relaparotomie nach 3monatiger postoperativer Uberlebenszeit wurden die Interponate an ausgewahlten Stellen morphometrisch untersucht. Als deutlichste Veranderung fiel bei allen Dunndarmersatzmagen eine starke muskulare Wandhypertrophie auf, die vor allem die Ringmuskulatur betraf. Beim Colonersatzmagen, der physiologisch eine dickere Wandmuskulatur besitzt, war die Hypertrophie sehr viel geringer. Als pathogenetischer Faktor dieser Veranderung gilt die Volumenbelastung, der der Ersatzmagen an dieser …
