amphetamine and Anoxemia

amphetamine has been researched along with Anoxemia in 21 studies

Amphetamine: A powerful central nervous system stimulant and sympathomimetic. Amphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulation of release of monamines, and inhibiting monoamine oxidase. Amphetamine is also a drug of abuse and a psychotomimetic. The l- and the d,l-forms are included here. The l-form has less central nervous system activity but stronger cardiovascular effects. The d-form is DEXTROAMPHETAMINE.
1-phenylpropan-2-amine : A primary amine that is isopropylamine in which a hydrogen attached to one of the methyl groups has been replaced by a phenyl group.
amphetamine : A racemate comprising equimolar amounts of (R)-amphetamine (also known as levamphetamine or levoamphetamine) and (S)-amphetamine (also known as dexamfetamine or dextroamphetamine.

Trial Overview

Trial Outcomes

Cognitive Performance-Fine Motor Function

Measured using the grooved pegboard task (number of seconds required to place 25 pegs using the dominant hand) (NCT03407729)
Timeframe: 20 minutes

Functional Activity During Executive Function Tasks

Subjects in each group were evaluated for changes in functional connectivity between the substantia nigra pars compacta (SNpc) and ventral tegmental area (VTA), as evaluated by functional magnetic resonance imaging blood oxygen level dependent (fMRI-BOLD), using whole brain analysis. The measurement is increase/decrease of MRI signal intensity in a given region, thresholded at p <0.05, summarized into a value representing 'size of region of increase' or 'size of region of decrease' after subjects' scans were combined/mapped onto a standard MNI brain. Only clusters of over 50 voxels were included, and the size of the region is reported in voxel size. The averaged brains for prematurely born fMRI was subtracted from the full term treatment for each group, and then these averaged differences were subtracted from each other. While other areas of the brain met threshold criteria in the analysis, only brain regions innervated by primary or collateral dopaminergic pathways are reported. (NCT03407729)
Timeframe: 30 minutes

Structural Integrity of Dopaminergic Circuits

Assessment of dopaminergic circuits originating in the substantia nigra pars compacta (SNpc) and ventral tegmental area (VTA). Includes right and left nucleus accumbens, right and left mamillary body, right and left hippocampus. Measured using Magnetic Resonance T1-weighted magnetization prepared rapid gradient echo (MPRAGE) scans with three-dimensional volumetrics analysis (NCT03407729)
Timeframe: 30 minutes
