This makes aspirin different from other NSAIDs (such as diclofenac and ibuprofen), which are reversible inhibitors; aspirin creates an allosteric change in the structure of the COX enzyme. [2] However, other effects of aspirin, such as uncoupling oxidative phosphorylation in mitochondria, [3] and the modulation of signaling through NF-κB, are ...
Thromboxane A 2 (TXA 2) is generated from prostaglandin H 2 by thromboxane-A synthase in a metabolic reaction which generates approximately equal amounts of 12-hydroxyheptadecatrienoic acid (12-HHT). Aspirin irreversibly inhibits platelet cyclooxygenase 1 preventing the formation of prostaglandin H 2 , and therefore TXA 2 .
Aspirin or other over-the-counter analgesics are widely recognized as effective for the treatment of tension headaches. [96] Aspirin, especially as a component of an aspirin/paracetamol/caffeine combination, is considered a first-line therapy in the treatment of migraine, and comparable to lower doses of sumatriptan. It is most effective at ...

acetylsalicylate + H 2 O salicylate + acetate. This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name is acetylsalicylate O-acetylhydrolase. Other names in common use include aspirin esterase, acetylsalicylic acid esterase, and aspirin hydrolase.
A North Carolina father is facing criminal charges after authorities allege he left his child isolated in a room with a space heater for more than 12 hours, leading to his death.
Water can be broken down into its constituent hydrogen and oxygen by metabolic or abiotic processes, and later recombined to become water again. While the water cycle is itself a biogeochemical cycle, flow of water over and beneath the Earth is a key component of the cycling of other biogeochemicals. [8]
