  • Publication number: 20210128507
    Abstract: Formulations, methods of manufacturing, methods of stabilizing, kits, and uses as medicament are provided, for example for the treatment of pain. The formulations can comprise gabapentin optionally combined with at least one non-opioid pain drug in an aqueous carrier. The pharmaceutical formulation can have a pH of about 2.0 to about 10.0. The at least one non-opioid pain drug can be acetaminophen. The components can be included in any amount suitable for purposes of obtaining properties desirable for an injectable infusion, for example an intravenous infusion.

  • Publication number: 20210066307
    Abstract: Systems, apparatuses, and methods related to semiconductor structure formation are described. An example method may include patterning a working surface of a semiconductor wafer. The method may further include performing a vapor etch on a first dielectric material at the working surface to recess the first dielectric material to a first intended depth of an opening relative to the working surface and to expose a second dielectric material on a sidewall of the opening. The method may further include performing a wet etch on the second dielectric material to recess the second dielectric material to the intended depth.

  • Publication number: 20210057266
    Abstract: An example method includes patterning a working surface of a semiconductor wafer. The example method includes performing a first deposition of a dielectric material in high aspect ratio trenches. The example method further includes performing a high pressure, high temperature vapor etch to recess the dielectric material in the trenches and performing a second deposition of the dielectric material to continue filling the trenches.

  • Patent number: 9296806
    Abstract: The invention provides processes for obtaining a precursor for insulin, analogs or derivatives thereof having correctly bonded cystine bridges. The process involves solubilizing a precursor of insulin, insulin analog or derivatives in an aqueous solution or a buffer containing cysteine or cysteine hydrochloride and one or more of chaotropic auxiliary. The solubilized precursors are refolded by adding diluent to the solubilized mixture (reverse dilution). Further, the solubilized precursors, wherein the concentration of precursor in reaction mixture is more than 0.65 g/liter can also be refolded by diluting the reaction mixture with a diluent optionally comprising about 5-40% v/v of one or more of alcoholic or aprotic solvents.
