Nereistoxin is a natural product identified in 1962 as the toxic organic compound N,N-dimethyl-1,2-dithiolan-4-amine. It had first been isolated in 1934 from the marine annelid Lumbriconereis heteropoda and acts by blocking the nicotinic acetylcholine receptor .
Olney's lesions, also known as NMDA receptor antagonist neurotoxicity (NAT), is a form of brain damage consisting of selective death of neurons but not glia, observed in restricted brain regions of rats and certain other animal models exposed to large quantities of psychoactive drugs that inhibit the normal operation of the neuronal NMDA receptor.
Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system. [1] It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant – alters the normal activity of the nervous system in such a ...
An editorial article on the paper indicated that researchers had observed dopaminergic neurotoxicity (death of neurons involved in dopamine pathways) in monkeys following MDMA injections, a finding which suggested that recreational users of MDMA may be at risk of developing neuropsychiatric disorders associated with dopamine dysfunction.
Drug resistance is the reduction in effectiveness of a medication such as an antimicrobial or an antineoplastic in treating a disease or condition. [1] The term is used in the context of resistance that pathogens or cancers have "acquired", that is, resistance has evolved.
Sometimes, whether an antibiotic is marked as resistant is also based on bacterial characteristics that are associated with known methods of resistance such as the potential for beta-lactamase production. [28] [20] Specific patterns of drug resistance or multidrug resistance may be noted, such as the presence of an extended-spectrum beta ...
“A salary is a drug they give you when they want you to forget about your dreams,” he said in an interview clip posted to his official YouTube channel. “Because it’s very easy to stay in ...
A drug of last resort (DoLR), also known as a heroic dose, [1] is a pharmaceutical drug which is tried after all other drug options have failed to produce an adequate response in the patient. Drug resistance , such as antimicrobial resistance or antineoplastic resistance , may make the first-line drug ineffective, especially in case of ...
