  • Patent number: 8921312
    Abstract: Provided is a method of stimulating collagen synthesis and proteoglycan (lumican and keratocan) accumulation. Collagenase isolated keratocytes were cultured with or without insulin with or without ascorbate. Insulin stimulates the synthesis of collagen but does not affect the accumulation of lumican and keratocan. Insulin plus ascorbate, however, stimulates the synthesis of collagen and increased the accumulation of these proteoglycans. The accumulation of PGDS, a KSPG that does not interact with collagen, is not affected by ascorbate. Only the collagen made in the presence of ascorbate was pepsin resistant. EDB overrode the effects of ascorbate on pepsin resistance and proteoglycan accumulation.

  • Publication number: 20130112087
    Abstract: A roasting pan is disclosed. The roasting pan may include a dual skewered system providing a stable mounting preventing pivoting and rotating of a mounted subject. The roasting pan may also include raised end walls providing a gap between the bottom surface of the subject and a base wall of the pan. The roasting pan may also include a lower profile side wall providing increased airflow to the sides, ends, and bottom of the subject.

  • Patent number: 4034664
    Abstract: A centrifuge-type apparatus for extracting, by pulverization and filtering under centrifugal force, the juice component from plant materials such as fruits or vegetables. Plant material introduced into the open top of a stationary hopper is pulverized upon contact with a series of fast-moving non-bladed, blunt protrusions extending upwardly from the surface of a rapidly rotating plate member extending across the open bottom of the hopper. The resultant juice and pulp mixture is then thrown outwardly under centrifugal force through an annular space of predetermined height formed between the bottom of the stationary hopper and the upper surface of the rotating plate. A frusto-conical filter member attached to and surrounding the rotating plate member impedes the outward motion of the pulp component of the pulverized plant material whle permitting the passage of the juice component.
