Abstract: Compositions and methods for inhibiting and/or sensitizing or re-sensitizing a parasite to an antiparasitic drug are provided. The compositions can comprise a rifamycin derivative or a pharmaceutically acceptable salt, hydrate, or prodrug thereof in an amount and formulation sufficient to inhibit or induce drug-sensitization in a parasite. The methods can comprise administering a rifamycin derivative or a pharmaceutically acceptable salt, hydrate, or prodrug thereof to a parasite in an amount and formulation sufficient to inhibit or induce drug-sensitization in the parasite.

Abstract: Endothelial dysfunction (ED) is associated with a number of diseases and disorders. Agonists of the non-proteolytically activated thrombin receptor can be used in methods to treat ED or ED-related diseases and disorders.

Abstract: Agonists of a non-proteolytically activated thrombin receptor, and more particularly, thrombin peptide derivatives, can be used in methods to cause smooth muscle relaxation. Compositions comprising thrombin peptide derivatives can be administered to a subject with a disease or disorder that can be ameliorated by relaxation of smooth muscle. Such compositions can also be administered to a subject to facilitate medical, diagnostic or surgical procedures.

Abstract: An agonist of a non-proteolytically activated thrombin receptor can be used in a method for treating peripheral arterial disease. The agonist can be a thrombin peptide derivative. In some embodiments, the peripheral arterial disease is characterized by intermittent claudication. The thrombin peptide derivatives to be used in the methods can have amino acid sequences similar to a region of thrombin. Usually, the thrombin peptide derivatives are 12-23 amino acid residues in length. In some cases, the thrombin peptide derivatives are dimers, and in particular, dimers that result from formation of a disulfide bond between two cysteine residues of peptide monomers.

Abstract: Various embodiments of the present invention concern improving the dosing accuracy and efficacy of systems that calculate medicine doses for injection in animals and prepare the correct dose in an automated syringe subsystem. In an embodiment, the improvement is gained by simultaneously protecting the medicine from ambient outdoor temperatures that thermally degrade its efficacy while precisely monitoring the amount of medicine remaining inside the source vial to prevent inadvertent under-dosing due to undetected source depletion. This dual-sleeve system (one for temperature, one for data storage concerning the source vial contents) forms an intelligent adjunct to current and future automated injection technology used to maintain healthy livestock.
