Predictive signs and indicators of aggressiveness and violence: a comparison between a group of adolescents attending an external penal area, a group…
2006
Aim. We considered the spreading and the increasing of aggressive and violent behaviours. The most of them have two common roots: lack of actual motivation and brutality. Our research intends to detect specific indicators and predictive signs of violent and aggressive behaviours. In order to this, scientific literature shows that the most reliable indicators and predictive signs are linked to structural personality features (e.g. defensive strategies, impulse control). Methods. This cross sectional study compares a group of 26 male adolescents with Conduct Disorder (F91.8), a group of 29 male patients with Borderline Personality Disorder (F60.31) and a group of 33 male prisoners with Antiso…
Quality of life, alexithymia, and defence mechanisms in patients affected by breast cancer across different stages of illness
2016
Objectives: The aim of this study was to evaluate the effect of alexithymia and defence mechanisms on the quality of life of patients affected by breast cancer at different stages of the disease. Methods A convenience sample of 110 patients with breast cancer was involved in the study: 41 were receiving adjuvant chemotherapyafter surgery, 29 had disease-free survival in follow-up and 40 were receiving chemotherapy for metastatic disease. Quality of life, alexithymia and defence mechanisms were assessed using the following instruments: EORTC QLQ-C30-BR23, Toronto Alexithymia Scale (TAS-20) and Defense Mechanism Inventory (DMI). Results Compared to the other groups, patients receiving chemoth…
Elimination of a bacterial pore-forming toxin by sequential endocytosis and exocytosis
2008
Staphylococcus aureus alpha-toxin is the archetype of bacterial pore forming toxins and a key virulence factor secreted by the majority of clinical isolates of S. aureus. Toxin monomers bind to target cells and oligomerize to form small beta-barrel pores in the plasma membrane. Many nucleated cells are able to repair a limited number of lesions by unknown, calcium-independent mechanisms. Here we show that cells can internalize alpha-toxin, that uptake is essential for cellular survival, and that pore-complexes are not proteolytically degraded, but returned to the extracellular milieu in the context of exosome-like structures, which we term toxosomes.
Pensiero e difese nei disturbi bipolari. Studio clinico e psicopatologico su bipolari I e bipolari II. Thinking organization and defense mechanisms i…
2013
Obiettivi. Scopo del presente studio è esplorare il funzionamento psichico dei soggetti con disturbo bipolare I e II attraverso l’analisi e il confronto degli stili di pensiero e dei pattern difensivi. Metodi. Nel corso di un intero anno solare (2009-2010), presso la clinica Psichiatrica del Policlinico Universitario di Palermo sono stati reclutati 29 pazienti con disturbo bipolare I e II. È stato somministrato il seguente protocollo: Wechsler Adult Intelligent Scale-R (WAIS-R) per valutare il funzionamento cognitivo generale; Defense Mechanisms Inventory (DMI) per misurare i pattern difensivi. Sono stati quindi ana- lizzati e confrontati i risultati ai due reattivi. Risultati. I soggetti c…
