BACKGROUND Depression is a frequent mood disorder that affects around 33% of stroke patients and has been associated with both poorer outcome and increased mortality. Our aim was to test the possible association between inflammatory and neurotrophic molecular markers and the development of post-stroke depression. METHOD We studied 134 patients with a(More)
Emerson and Kolm show that the proportion of species endemic to an island is positively related to its species richness and, assuming that endemism indexes speciation rate, they infer that greater species diversity accelerates diversification. Here we demonstrate that the same correlation between species richness and percentage endemism can arise even if(More)

INTRODUCTION AND DEVELOPMENT Leukoaraiosis is a radiological term which refers to white matter disturbances observed as a hypodensity in computed tomography and hyperintensity in T2-weighted magnetic resonance image. The most accepted theory to explain the mechanism of production of leukoaraiosis is chronic ischemia, due to a damage in penetrating arteries.(More)

Extinction risk has not been evaluated for 96% of all described plant species. Given that the Global Strategy for Plant Conservation proposes preliminary conservation assessments of all described plant species by 2010, herbarium specimens (i.e., primary occurrence data) are increasingly being used to infer threat components from estimates of geographic(More)
Multimedia information retrieval is vital for, among many other fields, design and engineering processes. Studies show that members of product development teams spend more and more time for information gathering and have less and less time for the creative aspects of their work. Here the combination of the still emerging Semantic Web [1] technologies and(More)
UNLABELLED Previous research has shown that antidepressants have been useful in the treatment of pain, particularly diabetic neuropathy. This study was an initial open investigation into the use of sertraline in diabetic neuropathy. Eight patients with diabetic neuropathy but not depression were treated with increasing doses of sertraline to a maximum of(More)
