Two main Rights Expression Languages (RELs) exist to describe licenses governing the access to digital content: ODRL (Open Digital Rights Language) and MPEG-21 REL. Both RELs are powerful and complex enough. The use of different RELs could divide the network commerce in two separate factions. In this paper we propose a way for interoperability between them.(More)
Colorectal cancer is the third most common cancer in both men and women and has shown a progressive increase over the past 20 years. Current chemotherapy has major limitations, and a novel therapeutic approach is required. Given that neoplastic transformation of colon epithelial cells is a consequence of genetic and epigenetic alterations, RNA interference(More)
Nanotechnology, along with related concepts such as nanomaterials, nanostructures and nanoparticles, has become a priority area for scientific research and technological development. Nanotechnology, i.e., the creation and utilization of materials and devices at nanometer scale, already has multiple applications in electronics and other fields. However, the(More)
Colorectal cancer is one of the most prevalent cancers in the world. Patients in advanced stages often develop metastases that require chemotherapy and usually show a poor response, have a low survival rate and develop considerable toxicity with adverse symptoms. Gene therapy may act as an adjuvant therapy in attempts to destroy the tumor without affecting(More)
The use of doxorubicin (DOX), one of the most effective antitumor molecules in the treatment of metastatic breast cancer, is limited by its low tumor selectivity and its severe side effects. Colloidal carriers based on biodegradable poly(butylcyanoacrylate) nanoparticles (PBCA NPs) may enhance DOX antitumor activity against breast cancer cells, thus(More)
The present study assessed the spatial abilities of male and female human participants using different versions of the non-navigational Corsi block-tapping test (CBT) and a search task. Males performed significantly better than females on the standard manual version of the CBT; however, the standard CBT does not allow discrimination between spatial memory(More)
The present research investigated the blocking effect in three different species, rats, humans and snails in formally equivalent tasks using a within-subjects design. Experiment 1 demonstrated the blocking effect in a context-flavour aversive conditioning preparation in rats: Animals failed to associate a flavour with an illness episode when it was(More)
In a two-dimensional computer-based search task, human participants were required to learn the location of a goal by using the geometric information available on the screen. When the goal location was defined by two shapes that differed in salience, the more salient shape overshadowed learning based on the less salient shape but not the other way round.(More)
