Malathion is an acetylcholinesterase inhibitor, a diverse family of chemicals.Upon uptake into the target organism, it binds irreversibly to the serine residue in the active catalytic site of the cholinesterase enzyme.
Excitotoxicity can occur from substances produced within the body (endogenous excitotoxins).Glutamate is a prime example of an excitotoxin in the brain, and it is also the major excitatory neurotransmitter in the central nervous system of mammals. [14]
Standard treatment for nerve agent poisoning is a combination of an anticholinergic to manage the symptoms, and an oxime as an antidote. [12] Anticholinergics treat the symptoms by reducing the effects of acetylcholine, while oximes displaces phosphate molecules from the active site of the cholinesterase enzymes, allowing the breakdown of ...
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 ...
Methylphenidate, sold under the brand names Ritalin (/ ˈ r ɪ t ə l ɪ n / RIT-ə-lin) and Concerta (/ k ə n ˈ s ɜːr t ə / kən-SUR-tə) [citation needed] among others, is a central nervous system (CNS) stimulant used medically to treat attention deficit hyperactivity disorder (ADHD) and, to a lesser extent, narcolepsy.
Isomalathion is an impurity found in some batches of malathion. Whereas the structure of malation is, generically, RSP(S)(OCH 3) 2, the connectivity of isomalathion is RSPO(SCH 3)(OCH 3). It arises by heating malathion. Being significantly more toxic to humans than malathion, it has resulted in human poisonings. [1]
Some of these products, they say, contain natural ingredients like maca and ginseng − which, though harmless, won't have much of any impact on your sex life, save for a placebo effect.
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.
