The Association Between Affective Temperament Traits and Dopamine Genes in Obese Population.

Studies indicate the heritable nature of affective temperament, which shows personality traits predisposing to the development of mental disorders. Dopaminergic gene polymorphisms such as , Val158Met, and have been linked to affective disorders in obesity. Due to possible correlation between the aforementioned polymorphisms and the affective temperament, the aim of our research was to investigate this connection in an obese population.

Links between parameters of long-term latent memory and progression from paroxysmal to permanent atrial fibrillation during a five-year observation period. A preliminary study.

Background And Aim: As cognitive function is the most vulnerable human feature, its impairment may precede the occurrence of symptoms of cardiovascular system disorders, e.g. atrial fibrillation (AF).

The polymorphisms in serotonin-related genes (5-HT₂A and SERT) and the prevalence of depressive symptoms in obese patients.

As overweight and obesity are a growing problem in industrialized societies, they become a main focus of many studies. The aim of this study was to determine whether there is an association between the occurrence of polymorphisms in serotonin-related genes and the prevalence of depressive symptoms in obese patients. Two polymorphisms were tested: a 44-bp insertion/deletion in the serotonin transporter (SERT) gene and a single-nucleotide variation (1438G/A) in the serotonin 2A receptor (5-HT2A) gene.
