  • Patent number: 8672123
    Abstract: A baby bottle comprised of an upper assembly, a lower assembly and a baffle assembly. The upper assembly is adapted to contain separately a wet ingredient and a lower assembly is adapted to contain a dry ingredient. The baffle assembly includes an integral plug and aperture that rotates relative to the upper assembly so that the upper assembly is selectively in fluid communication with lower assembly to mix the wet and dry ingredients.

  • Patent number: 8110399
    Abstract: Methods and compositions are described for the treatment of type I insulin-dependent diabetes mellitus and other conditions using newly identified stem cells that are capable of differentiation into a variety of pancreatic islet cells, including insulin-producing beta cells, as well as hepatocytes. Nestin and ABCG2 have been identified as molecular markers for pancreatic stem cells, while cytokeratin-19 serves as a marker for a distinct class of islet ductal cells. Methods are described whereby nestin and/or ABCG2-positive stem cells can be isolated from pancreatic islets and cultured to obtain further stem cells or pseudo-islet like structures. Methods for ex vivo differentiation of the pancreatic stem cells are disclosed. Methods are described whereby pancreatic stem cells can be isolated, expanded, and transplanted into a patient in need thereof, either allogeneically, isogeneically or xenogenically, to provide replacement for lost or damaged insulin-secreting cells or other cells.
