NCT05455086
This clinical trial studies the effect of free-base compared with nicotine salt based e-liquids on electronic cigarette (EC) puffing behavior, abuse liability, and deposition and absorption of nicotine in the respiratory tract and rate of uptake in the brain in current EC smokers. The results from this study may provide much needed scientific information to public health officials and regulators.
NCT05032105
The purpose of this study is to evaluate the feasibility, safety, and effects on anxiety of high intensity focused ultrasound ablation (FUSA) in patients suffering from treatment-refractory focal epilepsy and anxiety. FUSA is a non-invasive neurosurgical procedure that uses ultrasound waves, sent directly through the scalp and skull, to precisely target small abnormal areas of the brain. For this study, the targeted area of the brain is the anterior nucleus of the thalamus. This brain region may cause seizures and may also be involved in anxiety. The study will test if FUSA is safe and tolerated, and if it reduces anxiety and brain response to threat in patients with anxiety receiving the procedure for partial-onset epilepsy that is resistant to medications.
