what does pt in pt cruiser stand for
Chrysler PT Cruiser Internally at Chrysler during development, "PT" stood for "Plymouth Truck", as it was intended to be a Plymouth model, and certified as a truck by NHTSA standards. The name stuck, but Chrysler never revealed what PT was supposed to mean.
Cyclooxygenase In medicine, the root symbol "COX" is encountered more often than "PTGS". In genetics, "PTGS" is officially used for this family of genes and proteins, because the root symbol "COX" was already used for the cytochrome c oxidase family. Thus the two isozymes found in humans, PTGS1 and PTGS2, are frequently called COX-1 and COX-2 in the medical literature. The names "prostaglandin synthase (PHS)", "prostaglandin synthetase (PHS)", and "prostaglandin-endoperoxide synthetase (PES)" are older terms still sometimes used to refer to COX.
