BACKGROUND Behavioural variant of frontotemporal dementia (bvFTD) frequently presents complex behavioural changes, that rarely occur in isolation. Targeting behavioural phenotypes instead of single behavioural symptoms may potentially provide a disease model in which to investigate brain substrates of behavioural abnormalities. OBJECTIVE To identify(More)
OBJECTIVE The objective of this study was to investigate the cumulative effect of the genes likely involved in Alzheimer disease (AD)-related psychosis and their interaction with disease stage and environmental factors. METHODS Two hundred thirty-four patients with AD underwent clinical and neuropsychologic examination, behavioral and psychiatric(More)
BACKGROUND AND PURPOSE The role of mild hyperhomocysteinemia as a risk factor for cerebral ischemia may depend on stroke subtype. To test this hypothesis, we undertook a prospective case-control study of a group of patients with spontaneous cervical artery dissection (sCAD), a group of patients with atherothrombotic stroke (non-CAD), and a group of control(More)
BACKGROUND The gene encoding brain-derived neurotrophic factor (BDNF) has been suggested as a candidate for major depression, and for depression susceptibility in different neurological and psychiatric diseases. No study has investigated the role of BDNF genetic variation and depressive symptoms in Alzheimer's disease (AD). OBJECTIVE The aim of this study(More)
BACKGROUND AND PURPOSE Combinations of multiple predisposing polymorphisms and their interactions with modifiable factors may result in synergistic effects on the risk of ischemic stroke. These mechanisms are more likely to play a relevant role in younger individuals. METHODS The cumulative effect of the 20210A variant of prothrombin gene, the 1691A(More)
Several studies have been conducted to understand the genetic correlates of Alzheimer disease (AD)-related behavioral and psychological symptoms in dementia (BPSD). However, given that BPSD rarely occur in isolation, it has been suggested that targeting BPSD individually is too narrow of an approach if one wants to accurately define all the associated risk(More)
BACKGROUND APOE is the most recognized genetic risk factor for sporadic late-onset Alzheimer disease (AD). The role of APOE genotype in Lewy body dementia (LBD) is still unknown as well as the relationship between APOE genotype and cholesterol levels. OBJECTIVE The objective of this study was to explore the association between APOE genotype and(More)
BACKGROUND Despite best-possible medical management, many patients with end-stage cancer experience breathlessness, especially towards the end of their lives. We assessed the acceptability and effectiveness of non-invasive mechanical ventilation (NIV) versus oxygen therapy in decreasing dyspnoea and the amount of opiates needed. METHODS In this randomised(More)
The attention of this review is focussed on the mathematical modeling of the simultaneous processes of drug release and absorption/distribution/metabolism/elimination (ADME processes) following different administration routes. Among all of them, for their clinical importance, the oral, transdermal and local delivery are considered. The bases of the(More)
This paper deals with the development of proper mathematical models for the calculation of the in vivo rat intestinal drug permeability resorting to two different kinds of experimental methods: the single pass and the recirculating perfusion techniques. In particular, in the single pass case, attention is focused on the effect of water exchange between the(More)
