  • Publication number: 20210046025
    Abstract: The present invention relates to an injection for protecting ischemic myocardium, and preparation method for the injection. The emulsion for injection comprises, in parts by weight: 1-5 parts of N-suberoylanilide hydroxamic acid, 0.2-12.5 parts of n emulsifying agent, 2-100 parts of oil for injection, 0.02-5 parts of a solubilizer, 0.03-0.4 part of oleic acid, 0.4-12.5 parts of glycerinum, and the balance being water for injection. The emulsion for injection can effectively be used for increasing local drug concentration of the N-suberoylanilide hydroxamic acid in lipophilic organs such as angiocarpy and/or tissues before a cardiac interventional operation, increasing the bioavailability of the N-suberoylanilide hydroxamic acid, reducing general side effects of the N-suberoylanilide hydroxamic acid, realizing effective protection on myocardium under an ischemic or reperfusion injury state, and reducing or avoiding the occurrence of myocardial infarction.

  • Publication number: 20020049853
    Abstract: A secure electronic file transfer system and methods of its use are provided. The sender issues a request to the DAD (Digital Asset Distribution) system causing files residing on local or remote computers to be transferred to the recipient via application and TCP/IP protocols. Client software may be automatically downloaded and installed to the sending and/or receiving device to facilitate the packaging and transfer of said file to a DAD server, and said file may optionally be propagated from said DAD server to additional DAD servers and other non-DAD servers.
