Suicide, neuroendocrine dysfunction and CSF 5-HIAA concentrations in depressionDisinhibition of the hypothalamic-pituitary-adrenal (HPA) neuroendocrine system is characterized by high CSF cortisol concentrations and abnormal dexamethasone suppression test (DST) results. These two variables are strongly ...
Test preparation is important for accurate 5-HIAA test results. Foods rich in serotonin such as avocados, bananas, pineapples, plums, cantaloupes, grapefruits, plantains, melons, kiwi fruits, walnuts, hickory nuts, butternuts, pecans, tomatoes, and eggplants can interfere with 5-HIAA measurement...
Such serotonergic modulation in the amygdala is of great importance in normal emotional/ stressful signal processing, and dysregulation of the serotonergic system in the amygdala may result in abnormal responses of the amygdala to emotional stimuli and generation of anxiety and depression (Canli et al...
Karzinoide (Oberndorfer, 1907) sind seltene epitheliale Geschwülste, die vornehmlich im Verlaufe des Magen-Darm-Traktes einzeln oder multipel auftreten und die hier durch ein krankhaftes Wachstum der „gelben Zellen“ (Schmidt, 1905) der...
5P). These results suggest that TAND activates 5-HT1A receptor selectively and attenuates all abnormal behaviors-repetitive, social, and cognitive-by suppressing hyper-glutaminergic signaling in the PFC of prenatal VPA mice. Discussion Here, we investigated the involvement of glutamatergic-serotonergic ...

Depression is a polygenic and highly complex psychiatric disorder that remains a major burden on society. Antidepressants, such as selective serotonin reuptake inhibitors (SSRIs), are some of the most commonly prescribed drugs worldwide. In this review,
5-HT was subsequently transported into enterocytes by serotonin transporter (SERT) encoded by Scl6a4 gene, and then degraded into 5-hydroxyindoleacetic acid (5-HIAA) via monoamine oxidase (MAO), one isoform of which having greater affinity for 5-HT is MAO-A [31]. RT-qPCR was used to ...
(5-HIAA) appear to be lower in a subset of patients with MDD, especially those exhibiting suicidal behavior [19,20,21]. However, approximately 33% of MDD patients do not respond to treatment with a commonly used SSRI and 67% of patients do not remit to this first line treatment [22,...
