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)
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)
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.

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)
PURPOSE Acne vulgaris is a skin disorder of the sebaceous follicles, involving hyperkeratinization and perifollicular inflammation. Aberrant extracellular matrix remodeling due to matrix metalloproteinases (MMPs) has been associated with the presence of acne conditions. Given the complex pathophysiology of acne, novel topical therapies should include(More)
In the ultimatum game (UG), two players are involved to bargain over a division of a given sum of money. The proposer makes an ultimatum offer of a fraction of money, while the responder can either accept or reject the proposer's decision. In case of rejection of the proposed splitting by the responder, neither player gets anything. Adverse psychological(More)
OBJECTIVES Muscle wasting in patients with cancer has been linked to an increased activity of nuclear factor κB (NF-κB) and higher circulating levels of activin-A (ActA), a negative growth factor for muscle mass. Baicalin is a natural flavonoid that can reduce skeletal muscle atrophy in animal models of cancer cachexia by inhibiting NF-κB. This pilot(More)
