  • Patent number: 12218180
    Abstract: Various embodiments of the present disclosure are directed towards an integrated chip (IC). The IC comprises a substrate. A resistor overlies the substrate. The resistor comprises a first metal nitride structure, a second metal nitride structure spaced from the first metal nitride structure, and a metal structure disposed between the first metal nitride structure and the second metal nitride structure. A first dielectric structure is disposed over the substrate and the resistor.

  • Publication number: 20130085146
    Abstract: The present application is directed to lipid-drug complexes and related methods for producing stable lipid-drug complexes at or near the neutral pH range and administering pharmaceutical lipid-drug complexes to patients. In certain examples, the lipid-drug complex has a lipid-to-drug molar ratio of approximately 3:1. In certain examples, the lipid-drug complex may have lipid-to-drug molar ratios of less than 3:1 to 10:1 or higher. The present application is also directed to methods of administering a drug to a patient though subcutaneous injection of the lipid-drug complexes into particular tissues to effect higher localized concentrations of the at least one drug.

  • Publication number: 20040208921
    Abstract: Various embodiments of the present invention are directed to lipid-pharmaceutical compositions and related methods for producing a lipid-drug complex under conditions near the neutral pH range. Optimal pH range is provided for the efficient incorporation of various lipid-drug complexes. A lipid-drug complex, such as a liposome, readily encapsulates drugs having low aqueous solubility within a neutral pH range. In some embodiments, the lipid-drug complex comprises a lipid bilayer and a lipid-soluble drug having a range of molar ratio values of lipid-to-drug from about 3:1 to about 100:1 or higher for relatively toxic drugs. Lipid-drug complexes can also be formed within a range of molar ratios from about 3:1 to about 10:1, and a range of molar ratios from about 5:1 to about 7:1. In various embodiments, biomolecules, such as nucleic acids and proteins, that can have pharmacological activities may also be incorporated within lipid vesicles.
