Patriotism and pluralism: identification and compliance in the post-national polity
2009
The paper discusses the identity-building power and motivational force of patriotism. The basic idea underlying the discussion is that far from being a mere irrational and destructive force, patriotism is an expression of ‘existing human social identity.’ Thus, it argues that rather than dismissing patriotism altogether as an undesirable and/or irrational phenomenon, we need to understand how to discriminate between alternative forms of patriotism while investigating what constitutional reforms might be required to support those forms of patriotic identification that are morally desirable. I argue that to flourish, desirable forms of patriotism (what I call Ethical Patriotism) r…
Strongyloides natricissp. n. (Strongyloididae), un nouveau nématode parasite deNatrix maura(L. 1758) (Colubridae) en Espagne

Description d’une nouvelle espece de Nematode Strongyloididae, Strongyloides natricis sp. n. trouvee chez Natrix maura (L. 1758) (Colubridae), capturee a Mora de Rubielos, Teruel, Espagne. L’espece presente entre autres caracteres distinctifs une plus grande taille corporelle et des longueurs oesophagienne et caudale proportionnellement inferieures a celles de toutes les autres especes de ce genre.
Influence of cadmium on the morphology and functionality of haemocytes in the compound ascidian Botryllus schlosseri
2013
In order to get insights into the effects of cadmium (Cd) on cell morphology and functions, we exposed haemocytes of the colonial ascidian Botryllus schlosseri to sub-lethal concentrations of CdCl(2). Results indicate that Cd hampers haemocyte spreading and phagocytosis in a dose-dependent way, through the alteration of the actin cytoskeleton. In addition, the metal decreases the stability of the internal membranes, as revealed by the Neutral Red assay. The fraction of cells showing positivity for the lysosomal enzyme acid phosphatase is also reduced in the presence of Cd, whereas the number of cells responsive to the Annexin-V assay and showing chromatin condensation increases, suggesting …
Juba II, rey de los mauros y los libios
2013
Con la tesis Juba II, rey de los mauros y los libios, se analiza la transcendencia que para el Principado de Agusto tuvo la instauración de este príncipe norteafricano como rey de Mauritania. Partiendo del análisis de su origen númida y las relaciones de alianza y amistad que vincularon su familia a Roma, hechos de gran relevancia y ampliamente explicados en este trabajo, se acomete en profundidad el estudio de los restos numismáticos, epigráficos, literarios y arqueológicos que conducen a establecer las líneas de actuación de este monarca en su reino, a nivel socioeconómico, militar y político. En cuanto al primer ascpecto citado, del estudio realizado se desprende que este monarca llevó a…
RESUMEN EJECUTIVO DEL CONSENSO DE EXPERTOS SOBRE LA EFICACIA Y SEGURIDAD DE LOS iDPP-4 EN EL TRATAMIENTO DE PACIENTES CON DIABETES Y COVID-19
2021
Resumen Antecedentes El objetivo de este consenso es esclarecer el papel de los iDPP-4 en el manejo de los pacientes con diabetes durante la pandemia por COVID-19. Material y metodos Se llevo a cabo una busqueda bibliografica en PubMed (diciembre 2019-febrero de 2021). Se empleo la metodologia Oxford y se establecieron de forma consensuada posibles recomendaciones. Resultados La diabetes parece ser un factor independiente en la enfermedad de COVID-19 (evidencia 2b). No se demuestra mayor riesgo de contagio con iDPP-4 (evidencia 2b), y su uso ha demostrado ser seguro (evidencia 2b). Los iDPP-4 pueden presentar un cierto beneficio en la reduccion de la mortalidad, particularmente su uso intra…
Unravelling textural heterogeneity in obsidian:shear-induced outgassing in the Rocche Rosse flow
2016
Obsidian flow emplacement is a complex and understudied aspect of silicic volcanism. Of particular importance is the question of how highly viscous magma can lose sufficient gas in order to erupt effusively as a lava flow. Using an array of methods we study the extreme textural heterogeneity of the Rocche Rosse obsidian flow in Lipari, a 2. km long, 100. m thick, ~. 800. year old lava flow, with respect to outgassing and emplacement mechanisms. 2D and 3D vesicle analyses and density measurements are used to classify the lava into four textural types: 'glassy' obsidian (<. 15% vesicles), 'pumiceous' lava (>. 40% vesicles), high aspect ratio, 'shear banded' lava (20-40% vesicles) and lo…
Materials and Tools across Volcanoes: Exploitation of Georesources in Piano dei Cardoni (Ustica, Italy) during Prehistory.
2021
The paper aims at merging the first results from the analyses of the georesources exploited in the site of Piano dei Cardoni (Ustica island, Italy) during the Neolithic phases of its occupation (Middle-Late Neolithic, 4.7-4.2 ka cal BC). Grinding tools consist of a very varied typology of local volcanic rocks, easy to collect and available very close to the investigated site. A selection of shapes and lithology is applied to reach the best performance of the tools. The elevated number of grinders, pestles, mortars testify to an intense activity of food/plant processing in the site. The absence of chert or obsidian resources on the island pushed the human communities to import such raw ma…
Nemo regulates cell dynamics and represses the expression of miple, a midkine/pleiotrophin cytokine, during ommatidial rotation
2013
AbstractOmmatidial rotation is one of the most important events for correct patterning of the Drosophila eye. Although several signaling pathways are involved in this process, few genes have been shown to specifically affect it. One of them is nemo (nmo), which encodes a MAP-like protein kinase that regulates the rate of rotation throughout the entire process, and serves as a link between core planar cell polarity (PCP) factors and the E-cadherin–β-catenin complex. To determine more precisely the role of nmo in ommatidial rotation, live-imaging analyses in nmo mutant and wild-type early pupal eye discs were performed. We demonstrate that ommatidial rotation is not a continuous process, and …
Diabetes and Colorectal Cancer Risk: A New Look at Molecular Mechanisms and Potential Role of Novel Antidiabetic Agents.
2021
Epidemiological data have demonstrated a significant association between the presence of type 2 diabetes mellitus (T2DM) and the development of colorectal cancer (CRC). Chronic hyperglycemia, insulin resistance, oxidative stress, and inflammation, the processes inherent to T2DM, also play active roles in the onset and progression of CRC. Recently, small dense low-density lipoprotein (LDL) particles, a typical characteristic of diabetic dyslipidemia, emerged as another possible underlying link between T2DM and CRC. Growing evidence suggests that antidiabetic medications may have beneficial effects in CRC prevention. According to findings from a limited number of preclinical and clinical stud…
New body metrics to determine asteroid size and weight directly in the field
2015
Asteroids are an important group of predators in many marine ecosystems. The measure of body size is crucial in studying asteroid biology as this variable affects both prey selection and predation impact. Current field techniques for estimating asteroid size (i.e. total length TL, total weight TW) include the measure of correlated variables, such us the central disk (CD) and arm length (AL). However, these variables are often time-consuming and require a direct handling of the organism. We tested the accuracy of new asteroid body metrics, the arm height (AH) or arm width (AW), to rapidly estimate body size in asteroids. AH and AW were measured in three of the most common Mediterranean aster…
