I need an answer please

... gravis is to give an cholinesterase inhibitor such as neostigme (not to give acetylcholine intravenously?!)... it's action causes inhibition of acetylcholinesterase, which reduces the breakdown of acetylcholine... this means there is more acetylcholine in neuromuscular junctions and it removes ...

The Fiber Disease

... appropriate dose-response ranges for sarin and control chemicals. IC50 values were determined in chickens and mice for in vitro inhibition of acetylcholinesterase (AChE) and neuropathy target esterase (NTE). The results indicated PB neither inhibits NTE nor does it spare sarin's inhibition ...

epps?

... potentials. I'm trying to solve a problem that asks about how the EPP would change in different circumstances. I understand that if you add an acetylcholinesterase inhibitor, you would get a bigger, longer EPP. But what if you add just acetylcholine? I found two conflicting source, where one ...

organophosphate esters

... Organophosphate esters are neurotoxic and have been used in chemical warfare as well as our household pesticides. They basically act to inhibit acetylcholinesterase to prevent the breakdown of ACh in our synapses. Question here is, why are they do different in toxicity? Some OP are so low in ...
