Verbal and visuoperceptive semantic association in aMCI and AD patients
No full text"Objectives: The semantic impairment in Alzheimer’s patients was been largely studied. The deficit was observed by analyzing the categorization process, the event recalls, the recognition of the word/picture. Few studies were conducted on loss mechanisms of the knowledge and in specify in the degradation of semantic store and the decrease of categorization ability (see Peraita,2004). Few studies were oriented to verify the semantic associative ability. Passafiume (2012) suggested the in the semantic degradation in the dementia the information were lost by processes that initially interest the abstract relations and later on, with the progression of the cognitive degeneration, the relation more related at the perceptual storage system. Aim of study is to verify the progression of the loss of associative relations in cognitive deterioration not only in the dementia but in Mild Cognitive Impairment already. . Methods: The sample recruited in the study was divided in 4 groups: a) 19 subjects with Amnestic Mild Cognitive Impairment (aMCI) (mean age 71,0); 16 patients with mild Alzheimer’s Disease (AD) (mean age 72,0); 20 patients with moderate AD (mean age 74,3); 20 Normal Control (NC) (mean age 68,3). An experimental tasks battery carried out to evaluate the verbal and visuoperceptual semantic association abilities and to naming tasks (verbal naming and visuoperceptive naming). Results. Our results suggest a progressive impairment in the categorization ability tested by each experimental condition: in the naming tasks the AD patients have worse performances than NC and aMCI subjects. The statistical analysis show the performance in associative relations decreasing in the pathological groups and evidence the similar trend in semantic degradation both in visuoperceptual and verbal semantic associative tasks(F(12, 177,5)=8,2,p=0,000). The most interesting difference are in the comparison between the performance of aMCi and AD groups. The trend is confirmed even analyzing the performance of each of the 4 associative relation examined (the Function relation is the better preserved, while the Superordinate relation is the worse). . Conclusions: Our data seems to confirm the degradation of semantic store and to clear up the loss of semantic associative relations They suggest a degradation process based on gradual loss that in first time involve the information linked in abstract cognitive area and in a second time the information better related to the perceptive storage..

No full textVascular network organization in posterior atrophic human mandible: a guide for an appropriate surgical approach
No full textBackground: The bone vascularity plays a key role for a successful surgical approach during implant placement on the posterior
atrophic lower jawbone. Although, some very old references are reported on animal studies, to the author best knowledge no
data are present in literature regarding this subject.
Aim/Hypothesis: The aim of this work was to evaluate the vascular arrangement in posterior, edentulous, atrophic mandibular
crests on humans
Crise do capital: notas sobre os impactos na educação superior brasileira
No full textResumo: Trazemos à baila reflexões acerca da realidade da educação superior no Brasil, nos tempos coevos marcados pela crise do capital e pela adesão política do país à ofensiva neoliberal. O artigo resulta das experiências e reflexões da autora na sua vinculação orgânica com a temática. No cenário de degradação da universidade, precisamos estar atentos e mais do que nunca, combativos aos largos passos do desmonte da educação em favor dos interesses dos organismos internacionais Capital crisis: impacts on Brazilian higher education Abstract: We reflect on the reality of higher education in Brazil, in times characterized by the crisis of capital and the political adherence of the country to the neoliberal offensive. The article results from the author 's experiences and reflections in her organic relationship with the theme. In the scenario of university degradation, we need to be attentive and more than ever, combative to the broad steps of dismantling education in favor of the interests of international organizations

Indium selenide: An insight into electronic band structure and surface excitations
No full textWe have investigated the electronic response of single crystals of indium selenide by means of angle-resolved photoemission spectroscopy, electron energy loss spectroscopy and density functional theory. The loss spectrum of indium selenide shows the direct free exciton at similar to 1.3 eV and several other peaks, which do not exhibit dispersion with the momentum. The joint analysis of the experimental band structure and the density of states indicates that spectral features in the loss function are strictly related to single-particle transitions. These excitations cannot be considered as fully coherent plasmons and they are damped even in the optical limit, i.e. for small momenta. The comparison of the calculated symmetry-projected density of states with electron energy loss spectra enables the assignment of the spectral features to transitions between specific electronic states. Furthermore, the effects of ambient gases on the band structure and on the loss function have been probed
