Soman (or GD, EA 1210, Zoman, PFMP, A-255, systematic name: O-pinacolyl methylphosphonofluoridate) [1] is an extremely toxic chemical substance. It is a nerve agent , interfering with normal functioning of the mammalian nervous system by inhibiting the enzyme cholinesterase .
An example is through the nicotinic acetylcholine receptor (nAchRs), which is a receptor commonly found along the surfaces of the cells that respond to nicotine stimulation, turning them on or off. Aβ was found manipulating the level of nicotine in the brain along with the MAP kinase , another signaling receptor, to cause cell death.
The different wavelengths of light were directed into a sensor referred to as the photoacoustic cell. Within the cell were the vapors of different nerve agents. The traces of each nerve agent had a signature effect on the "loudness" of the lasers' sound wave tones. [65] Some overlap of nerve agents' effects did occur in the acoustic results.
An Astrocyte, a cell notable for maintaining the blood brain barrier. Ammonia toxicity is often seen through two routes of administration, either through consumption or through endogenous ailments such as liver failure. [89] [90] One notable case in which ammonia toxicity is common is in response to cirrhosis of the liver which results in ...
The blood of people killed by blood agents is bright red, because the agents inhibit the use of the oxygen in it by the body's cells. [2] Cyanide poisoning can be detected by the presence of thiocyanate or cyanide in the blood, a smell of bitter almonds, or respiratory tract inflammations and congestions in the case of cyanogen chloride ...
The blood–brain barrier (BBB) is a highly selective semipermeable border of endothelial cells that regulates the transfer of solutes and chemicals between the circulatory system and the central nervous system, thus protecting the brain from harmful or unwanted substances in the blood. [1]
Microbubbles are small "bubbles" of mono-lipids that are able to pass through the blood–brain barrier. They form a lipophilic bubble that can easily move through the barrier. [14] One barrier to this however is that these microbubbles are rather large, which prevents their diffusion into the brain. This is counteracted by a focused ultrasound.
A chemical weapon agent (CWA), or chemical warfare agent, is a chemical substance whose toxic properties are meant to kill, injure or incapacitate human beings.About 70 different chemicals have been used or stockpiled as chemical weapon agents during the 20th century, although the Organisation for the Prohibition of Chemical Weapons (OPCW) has an online database listing 35,942 chemicals which ...
