Through lines of D1 receptor mutant mice, it had also been implicated in mediating both the locomotor sensation and rewarding effects of cocaine. Acute cocaine injections induced c-fos and CREB expression via D1 receptors and repeat cocaine administration, which is associated with long lasting AP-1 transcription complexes containing ΔFosB ...
The effect of these structural changes on behavior is uncertain and studies have produced conflicting results. Two studies [18] [19] have shown that an increase in dendritic spine density due to cocaine exposure facilitates behavioral sensitization, while two other studies [20] [21] produce contradicting evidence.
These chemicals inhibit the action of DAT and, to a lesser extent, the other monoamine transporters, but their effects are mediated by separate mechanisms. Monoamine transporters are established targets for many pharmacological agents that affect brain function, including the psychostimulants cocaine and amphetamine. Cocaine and amphetamine ...
Depending on liver and kidney functions, cocaine metabolites are detectable in urine between three and eight days. Generally speaking benzoylecgonine is eliminated from someone's urine between three and five days. In urine from heavy cocaine users, benzoylecgonine can be detected within four hours after intake and in concentrations greater than ...
Cocaine is a relatively "balanced" inhibitor, although facilitation of dopaminergic neurotransmission is what has been linked to the reinforcing and addictive effects. In addition, cocaine has some serious limitations in terms of its cardiotoxicity [188] due to its local anesthetic activity. Thousands of cocaine users are admitted to emergency ...
Chemical structure of cocaine. The biosynthesis of cocaine has long attracted the attention of biochemists and organic chemists. This interest is partly motivated by the strong physiological effects of cocaine, but a further incentive was the unusual bicyclic structure of the molecule. The biosynthesis can be viewed as occurring in two phases ...
How does pink cocaine affect someone? It can be hard to determine how the drug cocktail may affect someone after ingesting it. WebMD said this is due to several factors: the types of drugs mixed ...
Cocaine- and amphetamine-regulated transcript, also known as CART, is a neuropeptide protein that in humans is encoded by the CARTPT gene. [ 1 ] [ 2 ] CART appears to have roles in reward, feeding, and stress, [ 3 ] and it has the functional properties of an endogenous psychostimulant .
