Creativity is important for social survival and individual wellbeing; science, art, philosophy and technology have been enriched and expanded by this trait. To our knowledge this is the first study probing differences in brain cerebral blood flow (CBF) between highly creative individuals (scientists and/or artists socially recognized for their contributions(More)
BACKGROUND Rhythm disturbances are a frequent clinical manifestation of depression. In recent years a possible relationship between depression and chronotypes has emerged. Specifically eveningness has been proposed as vulnerability factor. The aim of this study was to describe sleep features of depressed patients according to chronotypes and to explore(More)
The BDNF is required for the development and proper function of the central nervous system, where it is involved in a variety of neural and molecular events relevant to cognition, learning, and memory processes. Although only a functional mature protein is synthesized, the human BDNF gene possesses an extensive structural complexity, including the presence(More)
BACKGROUND Most adverse cutaneous drug reactions (ACDR) are mediated by delayed hypersensitivity (dh) with lymphocyte recruitment and inflammatory cytokines release, including tumour necrosis factor alpha (TNFalpha). Polymorphisms in the TNFalpha gene, such as the infrequent allele TNF2, predispose to certain inflammatory entities and enhance TNFalpha(More)
Sleep patterns, frequently altered in depression, have been hypothesized to be under genetic control. The circadian locomotor output cycles kaput (CLOCK) T3111C variant has been studied in association with sleep disturbances in depressed patients. The aim of this study was to investigate possible effects of T3111C CLOCK on insomnia, daytime sleepiness,(More)
In this study, we investigated whether polymorphisms of the dopamine D4 receptor (DRD4) gene were associated with psychotic symptomatology rather than with a unique diagnosis such as schizophrenia. A number of association studies between the DRD4 gene 48 bp-VNTR polymorphism at exon 3 and psychotic disorders have been reported, but the results have been(More)
Serotonin (5-HT) induces concentration-dependent metabolic effects in diverse cell types, including neurons, entherochromaffin cells, adipocytes, pancreatic beta-cells, fibroblasts, smooth muscle cells, epithelial cells, and leukocytes. Three classes of genes regulating 5-HT function are constitutively expressed or induced in these cells: (a) membrane(More)
OBJECTIVE The present study examined the psychobiological Temperament and Character model of personality on obsessive-compulsive disorder (OCD) patients, as well as the relation of temperament and/or character dimensions on the severity of obsessive-compulsive symptoms. METHODS Fifty-four subjects diagnosed with OCD, were assessed with the Temperament and(More)
