  • Patent number: 7671034
    Abstract: The invention relates to a stabilized premix feed or feed-like formulation that has an extended shelf life due to a decrease of the degradates of the active ingredient by controlling the amount of an already existing stabilizer in the formulation. The feed premix is used in the treatment of parasites in mammals, in particular swine and horses. The invention further relates to a method to extend the shelf life of a stable premix feed or feed-like formulation for the treatment of parasite infestation in swine and horses comprising controlling the amount of an already existing antioxidant or stabilizer in the formulation to decrease or to prevent the formation of acid/base catalyzed decomposition of the active ingredient.

  • Patent number: 7658341
    Abstract: The present invention encompasses a flow-through dispersion device for the dispersion of cell aggregates, the device comprising a first or upstream inlet obstacle and a second or downstream outlet obstacle, each obstacle having at least one traversing hole wherein no two holes align. Between the two obstacles is a turbulence chamber, such that when a cell suspension is passed through the inlet holes, into the chamber and then exits the second obstacle, the turbulence within the chamber disrupts and disperses cell aggregates. The device optionally may have more than two obstacles and turbulence chambers and multiple units may be placed in series to increase the amount of turbulence and time applied to a volume of cells. The invention further encompasses methods of using the device to disperse cell aggregates, and methods of culturing cells that involve seeding cultures and maintaining dispersed individual cells.
