The GSh-18 is a rotating-barrel, short recoil, locked-breech pistol with 10 locking lugs spaced equally around the barrel, the large locking surface area resulting in a strong lockup, [5] making it suitable for high-velocity ammunition loads.
Glutathione (GSH, / ˌ ɡ l uː t ə ˈ θ aɪ oʊ n /) is an organic compound with the chemical formula HOCOCH(NH 2)CH 2 CH 2 CONHCH(CH 2 SH)CONHCH 2 COOH. It is an antioxidant in plants , animals , fungi , and some bacteria and archaea .
In 2003, it was adopted as a standard sidearm for all branches of Russian military and law enforcement, alongside the Makarov PM, GSh-18, and SPS. Design details [ edit ]
Launched in 1999, the Neo Geo Pocket Color was SNK’s answer to Nintendo’s Game Boy Color. Though it hoped to revolutionize handheld gaming, the console ultimately fell short due to its shorter ...
Glutathione synthetase (GSS) (EC 6.3.2.3) is the second enzyme in the glutathione (GSH) biosynthesis pathway. It catalyses the condensation of gamma-glutamylcysteine and glycine, to form glutathione. [2]
Flavonoids, a type of antioxidant that combats oxidative stress in the body, has been found to help decrease the production of radical oxygen species (ROS) mostly by preventing the formation of free radicals but also partially by promoting the glyoxalase pathway via increasing transcription of GSH and GSH constituent subunits to increase ...
A second GSH molecule reduces the GS-SeR intermediate back to the selenol, releasing GS-SG as the by-product. A simplified representation is shown below: [5] RSeH + H 2 O 2 → RSeOH + H 2 O RSeOH + GSH → GS-SeR + H 2 O GS-SeR + GSH → GS-SG + RSeH. Glutathione reductase then reduces the oxidized glutathione to complete the cycle:
2 gsh + r-s-s-r → gssg + 2 rsh The GSH:GSSG ratio is therefore an important bioindicator of cellular health, with a higher ratio signifying less oxidative stress in the organism. A lower ratio may even be indicative of neurodegenerative diseases, such as Parkinson's disease (PD) and Alzheimer's disease .
