β-adrenergic receptors and G protein-coupled receptor kinase-2 in Alzheimer's disease: a new paradigm for prognosis and therapy?

Alzheimer's disease (AD) is a devastating form of dementia that imposes a severe burden on health systems and society. Although several aspects of AD pathogenesis have been elucidated over the last few decades, many questions still need to be addressed. In fact, currently available medications only provide symptomatic improvement in patients with AD without affecting disease progression. The β-adrenergic receptor (β-AR) system can be considered a possible target that deserves further exploration in AD. The central noradrenergic system undergoes substantial changes in the course of AD and β-ARs have been implicated not only in amyloid formation in AD brain but also in amyloid-induced neurotoxicity. Moreover, clinical evidence suggests a protective role of β-AR blockers on AD onset. In addition to that, post-receptor components of β-AR signaling seem to have a role in AD pathogenesis. In particular, the G protein coupled receptor kinase 2, responsible for β-AR desensitization and downregulation, mediates amyloid-induced β-AR dysfunction in neurons, and its levels in circulating lymphocytes of AD patients are increased and inversely correlated with patient's cognitive status. Therefore, there is an urgent need to gain further insight on the role of the adrenergic system components in AD pathogenesis in order to translate preclinical and clinical knowledge to more efficacious prognostic and therapeutic strategies

Analisi archeometriche di ceramica “appenninica” dalla pianura padana: importazioni, imitazioni o rielaborazioni

Nelle Valli Grandi Veronesi è attestata la sporadica presenza di ceramica appenninica, quindi in una zona esterna a quella della sua tradizionale diffusione. L’interpretazione di questo fenomeno può contribuire a comprendere la natura dei rapporti tra ambito padano e centro-italico nel Bronzo medio 3.Sono stati analizzati 13 vasi provenienti da Bovolone, Fabbrica dei Soci e Fondo Paviani di cui 7 con decorazione appenninica per definirne il luogo e la tecnologia di produzione (Rice 1987, Cuomo di Caprio 2007). Le analisi archeometriche effettuate sono: petrografica, analisi d’immagine, XRPD e XRF.Le ceramiche con decorazioni appenniniche rientrano nel campo di variabilità delle produzioni locali e possono essere definite imitazioni. Il fenomeno della ceramica appenninica nella valle padana sembra quindi legato alla circolazione di artigiani e modelli e non di prodotti finiti, anche se il numero di campioni analizzati finora non permette generalizzazioni di carattere storico.Sporadic fragments of appenninica pottery were discovered in Valli Grandi Veronesi, outside the main diffusion area. The interpretation of those occurances can help the interpretation of the interconnections between Po Valley and Central Italy during Middle Bronze Age 3.13 pottery have been analysed from Bovolone, Fabbrica dei Soci and Fondo Paviani, among them 7 with appenninica decoration in order to define their provenance and technology (Rice 1987, Cuomo di Caprio 2007). The archaeometrical analyses performed are: petrographic, digital image processing, XRPD and XRF. Results show that the pots decorated with the appenninic style share the same compositional range than the other ones and can be considered as locally produced. The presence of appenninca pottery in the Po Valley appear to be linked to the circulation of craftmen and models and not of final products, but the small number of samples investigated do not allow general historical conclusions

Supporting Web analytics by aggregating user interaction data from heterogeneous devices using viewport-DOM based heat maps

The players of the digital industry look at network Big Data as an incredible source of revenues, which can allow them to design products, services and market strategies ever more tailored to users' interests and needs. This is the case of data collected by Web analytics tools, which describe the way users interact with Web contents and where their attention focuses onto during navigation. Given the complexity of information to analyze, existing tools often make use of visualization strategies to represent data aggregated throughout separate sessions and multiple users. In particular, heat maps are often adopted to study the distribution of mouse activity and identify page regions that are more frequently reached during interaction. Unfortunately, since Web contents are accessed via ever more heterogeneous devices, region-based heat maps cannot be exploited anymore to aggregate data concerning user's attention, since the same Web content may move to another page location or exhibit a different aspect depending on the access device used or the user agent setup. This paper presents the design of a visual analytics framework capable to deal with the above limitation by adopting a data collection approach that combines information about regions displayed with information about page structure. This way, the well-known heat map-based visualization can be produced, where interactions can be aggregated on a per-element basis independently of the specific access configuration. Experimental results showed that the framework succeeds in accurately quantifying user's attention and replicating results obtained by manual processing

A multimodal interface for virtual character animation based on live performance and natural language processing

Virtual character animation is receiving an ever-growing attention by researchers, who proposed already many tools with the aim to improve the effectiveness of the production process. In particular, significant efforts are devoted to create animation systems suited also to non-skilled users, in order to let them benefit from a powerful communication instrument that can improve information sharing in many contexts like product design, education, marketing, etc. Apart from methods based on the traditional Windows-Icons-Menus-Pointer (WIMP) paradigms, solutions devised so far leverage approaches based on motion capture/retargeting (the so-called performance-based approaches), on non-conventional interfaces (voice inputs, sketches, tangible props, etc.), or on natural language processing (NLP) over text descriptions (e.g., to automatically trigger actions from a library). Each approach has its drawbacks, though. Performance-based methods are difficult to use for creating non-ordinary movements (flips, handstands, etc.); natural interfaces are often used for rough posing, but results need to be later refined; automatic techniques still produce poorly realistic animations. To deal with the above limitations, we propose a multimodal animation system that combines performance- and NLP-based methods. The system recognizes natural commands (gestures, voice inputs) issued by the performer, extracts scene data from a text description and creates live animations in which pre-recorded character actions can be blended with performer’s motion to increase naturalness
