Glucagon-like peptide-1 (GLP-1), a hormone released from enteroendocrine cells in the distal small and large intestines in response to nutrients and other stimuli, not only controls eating and insulin release, but is also involved in drinking control as well as renal and cardiovascular functions. Moreover, GLP-1 functions as a central nervous system peptide transmitter, produced by preproglucagon (PPG) neurons in the hindbrain. Intestinal GLP-1 inhibits eating by activating vagal sensory neurons directly, via GLP-1 receptors (GLP-1Rs), but presumably also indirectly, by triggering the release of serotonin from enterochromaffin cells.

Fluoxetine (FLX), a typical selective serotonin reuptake inhibitors, has been frequently detected in aquatic environment and wild fish. However, little is known about its effect on thyroid endocrine system. In the present study, zebrafish (Danio rerio) embryos were exposed to 1, 3, 10, and 30 μg/L of FLX for 6 days.

Background And Aims: Probe-based confocal endomicroscopy (pCLE) allows real-time microscopic visualization of the intestinal mucosa surface layers. Despite remission achieved through anti-tumor necrosis factor or vedolizumab therapy, anomalies in the intestinal epithelial barrier are observed in inflammatory bowel disease (IBD) patients. Our study aimed to assess these abnormalities in non-IBD individuals and compare them with IBD patients in endoscopic remission to identify the associated factors.

Stroke remains a leading cause of death globally, with survivors facing both physical and psychological challenges. While acute stroke treatment has improved, many patients develop post-stroke anxiety (PSA), particularly generalized anxiety disorder. PSA represents a significant clinical challenge as most stroke survivors suffer from it.

Personality disorders (PDs) are psychiatric conditions characterized by enduring patterns of cognition, emotion, and behaviour that deviate significantly from cultural norms, causing distress or impairment. The aetiology of PDs is complex, involving both genetic and environmental factors. Genetic studies estimate the heritability of PDs at 30% to 60%, implicating genes involved in neurotransmitter regulation, such as those for serotonin transporters and dopamine receptors.
