Our current knowledge of the neurobiology of romantic love remains scanty. In view of the complexity of a sentiment like love, it would not be surprising that a diversity of biochemical mechanisms could be involved in the mood changes of the initial stage of a romance. In the present study, we have examined whether the early romantic phase of a loving(More)
Eotaxin (CCL11) is an eosinophil-specific chemoattractant which has been found to be highly expressed at sites of vascular pathology. In the present study, we aimed to evaluate the association of plasma eotaxin levels with the presence and extent of angiographic coronary artery disease (CAD). Three hundred and fifty six consecutive patients attending for(More)
The ultimatum game (UG), a well-studied decision task used in experimental neuroeconomics, represents a simple two-person bargaining between a proposer and a responder. The proposer offers the responder how to split a sum of money. The responder decides whether to accept or reject the offer. When the responder accepts it, each player earns money according(More)
Programmed cell death and alterations in intracellular G-protein signaling may be involved in the pathophysiology of schizophrenia. The Galphas subunit of heterotrimeric G-proteins, encoded by the gene GNAS1, may play a role in both of these processes. Additionally, transgenic mice expressing a constitutively active form of Galphas provide a reliable model(More)
BACKGROUND Cellulite is a common complex cosmetic problem for many post-adolescent women characterised by relief alterations of the skin surface, which give the skin an orange-peel appearance. Although genetic factors have been suggested to play a role in the development of cellulite, the genetic background of this condition remains unclear. We therefore(More)
OBJECTIVE To study vascular endothelial growth factor (VEGF) and its soluble receptors sVEGFR-1 and -2 in autism. DESIGN AND METHODS We measured serum levels of angiogenic molecules in 22 patients with severe autism and 28 controls. RESULTS Patients and controls had similar sVEGFR-2 levels, but VEGF levels were lower and sVEGFR-1 higher in patients with(More)
The exposure of human skin to ultraviolet radiation (UVR) results in the formation of DNA photolesions that give rise to photoaging, mutations, cell death and the onset of carcinogenic events. Photolyase (EC is a DNA repair enzyme that reverses damage caused by exposure to UVR. We sought to investigate whether addition of photolyase enhances the(More)
This open-label trial assessed the clinical efficacy of L-5-hydroxytryptophan (5-HTP), a natural serotonin precursor, in nondepressed young subjects with high levels of romantic stress. Since both neurotrophins and serotonin have been linked to human romantic attachment, we sought to investigate the changes in serum brain-derived neurotrophic factor (BDNF)(More)
Alpha2-Heremans-Schmid glycoprotein (AHSG), also known as fetuin-A, is a highly glycosylated protein which has been recently reported to be decreased in the cerebrospinal fluid of patients with Alzheimer's disease. AHSG is genetically polymorphic and two common alleles, AHSG*1 and AHSG*2, have been described. The purpose of this study was to investigate the(More)
OBJECTIVE High levels of neuroticism and low self-esteem are markers for vulnerability to depression, a condition associated with a higher risk of arrhythmias. The question as to whether these depression-related personality domains are related to cardiac repolarization (duration of QT interval) in apparently healthy men has been addressed in this study.
