  • Publication number: 20210128695
    Abstract: A composition and method of maintaining fertility or treating retained placenta, reproductive tract infection, or reproductive tract inflammation in an animal involves administering ovotransferrin to the reproductive tract of the animal. The ovotransferrin administration protects against and treats reproductive tract infection, while protecting against and treating reproductive tract inflammation such as metritis, and thereby maintains fertility in the animal.

  • Publication number: 20170290915
    Abstract: Described herein are methods for delivering an anti-cancer agent to a tumor in a subject. The method involves administering to the subject (i) gold particles and (ii) at least one-anti-cancer agent directly or indirectly bonded to the macromolecule and/or unbound to the macromolecule; and exposing the tumor to light for a sufficient time and wavelength in order for the gold particles to achieve surface plasmon resonance and heating the tumor.

  • Publication number: 20160166693
    Abstract: Described herein are anti-cancer compounds composed of a macromolecule comprising (1) at least one anti-cancer agent directly or indirectly bonded to the macromolecule and (2) at least one high Z element directly or indirectly bonded to the macromolecule that is capable of producing Auger electrons upon exposure to X-ray energy. When the compounds are exposed to low energy X-ray (e.g., kilo electron volts KeV) Auger electrons are produced by the high Z elements present in the compound. Because lower energy is required when compared to typical radiotherapy, which uses therapeutic X-ray energy in the million electron volt range (MeV), the subject experiences lower collateral damage when compared to radiation therapy. Additionally, the presence of the anti-cancer agent provides a second mechanism for killing cancer cells. Methods for making and using the anti-cancer compounds are also described herein.
