In the technical documents of international drug registration application, CTD refers to the name of the file format uniformly used by such documents.
Let's take a look at CTD:
1. Biological concept.
CTD, a concept in molecular biology. The carboxyl terminal domain of the large subunit of RNA polymerase ⅱ (polymerase). Seven amino acids (tyrosine-serine-proline-threonine-serine-proline-serine). Phosphorylation of serine and some tyrosine in CTD sequence is necessary for enzyme activity.
2. Communication industry.
CTD (Click to Dial) is a call initiated by the server. After the user arrives at the CTD service platform with the CTD request of CTD initiator and CTD calling and called, the CTD service platform establishes the call connection between CTD calling and called.
3. Biomedicine.
CTD (connective tissue disease), connective tissue disease and connective tissue disease are a large class of autoimmune diseases characterized by involving multiple organs and systems. Include systemic sclerosis, mixed connective tissue disease and systemic lupus erythematosus. [ 1]?
4. Treasury bond futures.
CTD (cheapest delivery), the cheapest deliverable voucher. In the treasury bond futures trading, the coupon rate, maturity time and final market price of treasury bonds that can be used for treasury bond futures delivery are very different; Therefore, it is stipulated that the "standardized" process must be introduced in the future delivery of national debt, which is also the conversion factor that we discussed repeatedly in the previous report. However, even if there is a conversion factor, the market price of government bonds divided by a conversion factor may still be different, which hides the concept of the cheapest deliverable cash bonds. Obviously, the lowest price of adjusted cash bonds is CTD cash bonds.
5. Terms of the game.
CTD(Crush To Desktop) literally means crashing back to the desktop, but in the game it is the phenomenon that the main interface pops up to the desktop due to the conflict caused by an operation. At this time, game developers need to provide timely follow-up technical support, modify programs, and provide vulnerability patches.
