Clinical and preclinical evidence suggests that mecamylamine, a nicotinic receptor antagonist, may have anxiolytic properties. The purpose of this study was to further investigate the anxiolytic properties of mecamylamine in rats as measured by the Elevated Plus Maze and the Social Interaction models of anxiety and to determine if manipulation of the testing environment (either brightly lit or dimly lit conditions) influenced the results. Results indicated that mecamylamine had significant anxiolytic effects in both the Elevated Plus Maze and Social Interaction Tests and that these effects were dependent on dose administered and the level of anxiety produced under different testing conditions. If confirmed by further clinical research, nicotinic receptor antagonists like mecamylamine may represent a novel class of anxiolytics.

Objectives: Our aim was to evaluate the comparative effects of sertraline and vortioxetine against stress-induced brain injury in rats.
Methods: The rats were assigned to a nonstress group (NSG), stress-treated control (StC), sertraline + stress (SSt), and vortioxetine + stress (VSt) groups. Sertraline and vortioxetine (10 mg/kg) were given orally by gavage to the SSt and VSt groups.

Magnetic resonance imaging (MRI) is a powerful diagnostic tool that uses strong magnetic fields and radio waves to create detailed images of the body's internal structures. This article examines the challenges associated with MRI, particularly focusing on patient anxiety and claustrophobic reactions that can lead to aborted scans. It discusses the use of anxiolytics, especially benzodiazepines, to manage these issues, while highlighting the potential risks of respiratory depression and other adverse outcomes in select patient populations.

Cannabidiol (CBD), a phytocannabinoid, has emerged as a promising candidate for addressing a wide array of symptoms. It has the ability to bind multiple proteins and receptors, including 5-HT1AR, transient receptor potential vanilloid 1 (TRPV1), and cannabinoid receptors. However, CBD's pharmacodynamic interaction with 5-HT1AR and its medicinal outcomes are still debated.

Diabetic kidney disease (DKD) is the leading cause of chronic kidney disease. Current treatments for DKD do not halt renal injury progression, highlighting an urgent need for therapies targeting key disease mechanisms. Our previous studies demonstrated that activating the Sigma-1 receptor (S1R) with fluvoxamine (FLU) protects against acute kidney injury by inhibiting inflammation and ameliorating the effect of hypoxia.

Dexmedetomidine (DEX) is a selective alpha-2 adrenergic receptor agonist with sedative and anxiolytic properties. Increasing evidence reports that DEX has a neuroprotective effect. In this study, we investigated the potential effects of DEX on learning and memory functions in rats with experimental cognitive impairment.
