Extradigital glomus tumour causing thigh pain: a case report

Glomus tumours are rare and benign, arising from a neuromyoarterial glomus body, most commonly in the hand. We report a patient with such a tumour in an atypical site, the right vastus lateralis. Pain was aggravated by muscle contraction, and ultrasonography and MRI were required to locate the lesion accurately. Surgical excision gave immediate pain relief

Evaluación de la migración de bromuro de cetilpiridinio desde nanocompósitos activos hacia un simulante graso de alimentos/Cetylpyridinium bromide migration assessment from active nanocomposites to a fatty food simulant

En los últimos años, el desarrollo de nanocompósitos poliméricos se plantea como una interesante alternativa para el diseño de nuevos materiales para el envasado activo de alimentos. A pesar de esto, existe constante preocupación relacionada a la migración de los componentes activos incorporados en el material ya que, un material de envasado destinado a entrar en contacto con un alimento debe presentar valores de migración bajo los límites establecidos en regulaciones internacionales. En este sentido, el objetivo del presente trabajo fue evaluar la migración del surfactante bromuro de cetilpiridinio (CPB) desde nanocompósitos activos de polietileno de baja densidad y montmorillonita modificada con CPB, hacia un simulante graso de alimentos (etanol 95 %). El seguimiento de la migración del componente se realizó a través de la medición de la conductividad eléctrica del simulante en contacto con los nanocompósitos. Se determinó que la presencia del 3,0 % de organoarcilla permite una mayor migración del CPB debido a la presencia del surfactante libre en la matriz y al hinchamiento de la organoarcilla superficial por hidratación. Además, se observó que la migración es prolongada en el tiempo y está por debajo de los límites permitidos por la legislación estadounidense, lo que permitiría la generación de materiales novedosos que podrían ser empleados en el diseño de envases activos de alimentos. In the last years, the development of polymeric nanocomposites is presented as an interesting alternative for the design of new materials for active food packaging. Despite this, there are concerns regarding the migration of the components incorporated in the material since a packaging material intended to come into contact with food must have migration values under the limits established in international regulations. In this sense, the aim in this work was to evaluate the migration of the surfactant cetylpyridinium bromide (CPB) from active nanocomposites of low density polyethylene and motmorillonite modified with CPB to a fatty food simulant (ethanol 95 %). The migration of the component was followed by fat simulant electrical conductivity measurements during the contact with the nanocomposites. It was determined that materials with 3,0 % of organoclay allowed a higher migration of CPB due to the presence of free surfactant in the matrix and swelling of the superficial organoclay. In addition, it was observed that the migration is prolonged in time and it is below the limits allowed by US legislation, which would enable the generation of novel materials that could be used in the design of active food packaging. Palabras clave: surfactante, conductividad eléctrica, polietileno de baja densidad, organoarcilla, envase activo de alimentos. Keywords: surfactant, electrical conductivity, low density polyethylene, organoclay, food active packaging

Integration in the European higher education area: the case of military education

Military training has always been considered as an education system with its own characteristics that distinguished it from the rest of higher education. However, different initiatives have been developed in order to integrate military education in the European Higher Education Area (EHEA). This paper analyses the European system of military institutions of higher education (MHEI). Results indicate MHEI sector has distinctive features that have increased the diversity of European HEIs. Further, the emergence of the MHEI sector can have benefits for both the European defence and their educational attainment. From a defence point of view, it can help the development of a European strategic culture and increase cooperation between countries in defence and security. From the education area modernisation, it will improve defence and security related research and may enhance defence knowledge transfer. In this way, the MHEI sector will be positioned as key player in the development of the Common Security and Defence Policy and a European strategic culture

Do investors react to corporate governance news? An empirical analysis for the Spanish market

This work adds to the debate on corporate governance regulations and its effects on performance and firm value. The paper empirically tests whether there is a significant price reaction to corporate governance announcements following the publication of the Aldama Code of Best practice (2003) in Spain. In particular, news announcements are classified according to the code principles to distinguish among different dimensions of corporate governance and have a better understanding of investors'' reaction. Results show first, that investors react to this kind of practices, second, that the sign of their reaction depends crucially on the nature and extension of the recommendation and finally that firms that disclose more do not enjoy higher market prices or return on the medium-long term

Endoscopic diagnosis of gastric peptic ulcer penetrating into the liver

A 61-year-old man was admitted with upper gastrointestinal bleeding. Endoscopy showed a large gastric peptic ulcer with a pseudotumoral mass protruding from the ulcer bed. Histological examination of biopsies taken from the mass revealed distorted hepatic tissue and inflammatory changes. Hepatic penetration was diagnosed as the cause of bleeding. Surgery findings confirmed the endoscopic diagnosis

Analysis of variance in household financial portfolio choice: evidence from Spain

We analyse the determinants of the household financial portfolio allocation using an estimator and a variance decomposition that take into account the constrained nature of household portfolio allocations. We apply these methods to a large data set of financial assets. Results show that the main factors underlying household financial portfolio choice in Spain are age and net wealth. Among others, there is also evidence of sizeable effects associated with risk aversion, education, liquidity constraints and income, but very modest effects are associated with family size and having accounts in stand-alone internet banks. Implications for policy are also derived
