Introduction: Aggression and self-harm disproportionately occur in youths preoccupied with social status tracking. These pathological conditions are linked to a serotonin (5-HT) deficit in the brain. Ablation of 5-HT biosynthesis by tryptophan hydroxylase 2 knockout (TPH2-KO) increases aggression in rodents.

Consequently, therapies that improve LAS may help reduce AF-related adverse cardiac events. We aimed to compare how digoxin and bisoprolol modulate LAS in patients with AF being treated with rate control.

PhE is also used as a biocidal component in occupational settings. A previous volunteer study by our working group following oral exposure to PhE showed that PhE is almost completely taken up into the human body followed by an extensive metabolization and fast urinary elimination.

- Gallstone disease significantly strains healthcare resources, particularly through emergency cholecystectomy, yet there's limited research on the risk factors that lead to such emergencies in patients scheduled for elective surgery.
- A study conducted in Jeddah, Saudi Arabia, analyzed 823 patients, revealing that 15.67% underwent emergency cholecystectomy, often due to longer waiting times and previous emergency department visits.
- Key findings indicated that patients with acute cholecystitis or pancreatitis, and those with multiple prior ED visits, are at a much higher risk of requiring emergency surgery.
Serotonin exerts numerous neurological and physiological actions in the brain and in the periphery. It is generated by two different tryptophan hydroxylase enzymes, TPH1 and TPH2, in the periphery and in the brain, respectively, which are members of the aromatic amino acid hydroxylase (AAAH) family together with phenylalanine hydroxylase (PAH), degrading phenylalanine, and tyrosine hydroxylase (TH), generating dopamine. In this study, we show that the co-chaperone DNAJC12 is downregulated in serotonergic neurons in the brain of mice lacking TPH2 and thereby central serotonin.
