  • Publication number: 20230241019
    Abstract: A method comprising administering to a subject having an aneurysm, suspected of having an aneurysm, or at risk of developing an aneurysm, a therapeutically effective amount of a compound selected from (i) a nitroalkene fatty acid, (ii) an unsaturated fatty acid having an electron withdrawing group, a leaving group, and a carbon-carbon double bond disposed between the electron withdrawing group and the leaving group, (iii) a thiolated nitro fatty acid, (iv) a dicarboxylic acid compound containing an electron withdrawing group, or a mixture of at least two of (i)-(iv).

  • Patent number: 11710623
    Abstract: A processing chamber such as a plasma etch chamber can perform deposition and etch operations, where byproducts of the deposition and etch operations can build up in a vacuum pump system fluidly coupled to the processing chamber. A vacuum pump system may have multiple roughing pumps so that etch gases can be diverted a roughing pump and deposition precursors can be diverted to another roughing pump. A divert line may route unused deposition precursors through a separate roughing pump. Deposition byproducts can be prevented from forming by incorporating one or more gas ejectors or venturi pumps at an outlet of a primary pump in a vacuum pump system. Cleaning operations, such as waferless automated cleaning operations, using certain clean chemistries may remove deposition byproducts before or after etch operations.

  • Publication number: 20210220315
    Abstract: Nitro oleic acid and related metabolites are agonists of PPAR-?. Surprisingly, nitro oleic acid is a more potent agonist of PPAR-?, relative to nitro linoleic acid. Thus, nitro oleic acid and its metabolites, as well as their pharmaceutically acceptable salts and prodrug forms, are candidate therapeutics for the treatment of type-2 diabetes, which results from insulin resistance accompanying the improper functioning of PPAR-?.
