Assessment of salivary and serum antioxidant status in patients with recurrent aphthous stomatitis

2009

Objective: The aim of this study was to determine the possible association of oxidant/antioxidant status and recurrent aphthous stomatitis (RAS). Study design: The study consis ted of thirty-one patients with RAS and thirty-two healthy controls from whom saliva and blood samples were collected. Superoxide dismutase (SOD), glutathione peroxidase (GSHPx) and catalase (CAT) were measured in erythrocytes and total antioxidant status (TAS) was measured in plasma and saliva. Results: Erythrocyte SOD activity was significantly lower in RAS patients in comparison to healthy controls (P=0.012). No significant differences were found in erythrocyte GSHPx, CAT activities, and salivary and plasma TAS be…

Demographic and behavioural profiles of patients with common oral mucosal lesions by a homogeneity analysis

2012

Objective: The aim of this study is to assess the main oral mucosal lesions (OMLs) within a hospital base and to provide an anamnestic, diagnostic model based on homogeneity analysis of some variables. Methods: The demographic and behavioural data (i.e. gender, age, smoking status, alcohol consumption and therapeutic drug usage) of 1753 patients with at least one OML were considered. Multiple correspondence analysis (MCA) and multivariate tests of the simultaneous marginal homogeneity hypothesis (SMH) were used to analyse the evidence of any differences between the demographic and behavioural profiles relating to OMLs diagnoses. Statistical significance of P<0.05 was chosen. Results: With r…

Data from: Moving in the Anthropocene: global reductions in terrestrial mammalian movements

2019

Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral changes of individual animals and to the exclusion of species with long-range movements from areas with higher human impact. Global loss of vagility alters a key ecological trait of animals that affects no…

Processi cognitivi e soluzioni di problemi matematici con studenti italiani e cinesi

2012

To compare cognitive processes adopted by students with different cultures in solving mathematical problems we have to focus on the Math epistemology through a cultural analysis concerning the fundamental elements of the students different cultural traditions and the philosophical, logic and linguistic bases subtended to the mathematical thought and its historical evolution. The paper describes this theoretical framework, emphasizing a possible comparison between different cognitive styles and mathematical problem solutions in the context of arithmetic and Algebraic thought of Italian and Chinese students in multicultural classes.

Ontogenesis and phylogenesis in the passage from arithmetic to algebraic thought

2012

With this work we retrace some of the fundamental historical and historical epistemological steps of the evolution of algebraic thought. Given the accepted parallelism between ontogenesis and phylogenesis we believe such a research to be a useful approach to the interpretation of obstacles and difficulties that students encounter during the acquisition of algebraic thought.

Counter-Clock World: How Planning Backwards Helps in Moving Forward in Collapsing Environments

2021

Research on corporate decline and turnarounds as well as the strategic use of history have so far remained two separate research fields. We integrate these two fields with a thought experiment, proposing ways in which strategists can work with, and through time in managing and turning around declines. Our thought experiment involves two very different types of analogies: a textual one from Philip K. Dick’s science fiction novels, on the one hand, and a visual one from Einsteinian relativity science, on the other hand. Inspired and informed by these different conceptualizations of the past and time, we develop four forms of backward strategizing to successfully manage a struggling corporatio…

Part 1—You can run but you can't hide: Intrusive thoughts on six continents

2014

Abstract Most cognitive approaches for understanding and treating obsessive-compulsive disorder (OCD) rest on the assumption that nearly everyone experiences unwanted intrusive thoughts, images and impulses from time to time. These theories argue that the intrusions themselves are not problematic, unless they are misinterpreted and/or attempts are made to control them in maladaptive and/or unrealistic ways. Early research has shown unwanted intrusions to be present in the overwhelming majority of participants assessed, although this work was limited in that it took place largely in the US, the UK and other ‘westernised’ or ‘developed’ locations. We employed the International Intrusive Thoug…

Multiplicity results for asymptotically linear equations, using the rotation number approach

2007

By using a topological approach and the relation between rotation numbers and weighted eigenvalues, we give some multiplicity results for the boundary value problem u′′ + f(t, u) = 0, u(0) = u(T) = 0, under suitable assumptions on f(t, x)/x at zero and infinity. Solutions are characterized by their nodal properties.

Verso una dimensione narrativa delle mappe

2021

Tra il pensiero e la costruzione dell’architettura il disegno ha un ruolo baricentrico per connettere i diversi protagonisti di una realizzazione e per coinvolgere la collettività facendo percepire inedite prospettive. La scrittura si rivela utile per esplicitare ciò che nella grafica è sotteso e per stabilire un ordine nuovo nel ragionamento progettuale. I rapporti fra segni e significati si moltiplicano nei sistemi informativi recenti in cui si ha la sensazione di poter dire moltissimo (dati numerici e spaziali) ma a volte sfugge quella sintesi indispensabile per una interpretazione concreta, finalizzata alla costruzione di possibili esperienze fisiche. Per l’esplorazione dell’uso di dive…
