  • Patent number: 11786581
    Abstract: The invention is directed to methods of inducing cell recruitment and tissue regeneration at a target site in a subject. It is also based, in part, on the discovery that a subject's own biologic resources and environmental conditions can be used for in situ tissue regeneration and thereby reduce or eliminate the need for donor cell procurement and ex vivo manipulation of such donor cells. Methods are disclosed for recruitment of a subject's own stem cells to a target region by inducing a sustained positive pressure at a target site, such as the kidney, thereby increasing the number of pluripotent cells capable of differentiating to regenerate the target tissue.

  • Publication number: 20110220125
    Abstract: A mandibular advancement splint provides for adjustable lateral movement of upper and lower appliances. An upper appliance is inserted onto a user's upper jaw and a lower appliance is inserted onto a user's lower jaw. A first protrusion is formed on the upper appliance. A second protrusion is formed on the lower appliance. One of the first protrusion and the second protrusion can be adjusted to offset the lower jaw with respect to the upper jaw. The splint can have an upper appliance having a body mounted to an upper jaw of a user; and a lower appliance having a body mounted to a lower jaw of a user. The upper appliance has a pair of adjustable wings attached to the upper appliance body; and the lower appliance has a pair of fixed wings attached to the lower appliance body. The pair of wings attached to said upper appliance are slidably adjustable with respect to the upper appliance body to determine the offset between the upper and lower jaws of the user.

  • Publication number: 20080089930
    Abstract: A hydratable, highly absorbent keratin solid fiber or powder capable of absorbing a large weight excess of water may be produced by partially oxidizing hair keratin disulfide bonds to sulfonic acid residues and reacting the sulfonic acid residues with a cation. The neutralized suspension can be filtered, washed, and dried, leaving keratin solid which can be shredded into fibers and further ground into powder. Addition of water to the solid produces a hydrogel. The powder or hydrogel may be useful as an absorbent material, as a therapeutic for skin, or as an excipient. The keratin materials can be incorporated into nonwoven films. The hydrogel can be used as a biocompatible viscoelastic filler for implant applications. Another use for the absorbent keratin and keratin hydrogel is as an excipient in pharmaceutical and cosmetic applications.

  • Publication number: 20050269127
    Abstract: A composite insulator containing means for providing early warning of impending failure due to stress corrosion cracking, flashunder, or destruction of the rod by discharge activity conditions is described. A composite insulator comprising a fiberglass rod surrounded by a polymer housing and connected with metal end fittings on either end of the rod is doped with a dye-based chemical dopant. The dopant is located around the vicinity of the outer surface of the fiberglass rod. The dopant is formulated to possess migration and diffusion characteristics, and to be inert in dry conditions and compatible with the insulator components. The dopant is positioned within the insulator such that upon the penetration of moisture through the housing to the rod through a permeation pathway in the outer surface of the insulator, the dopant will become activated and will leach out of the same permeation pathway or diffuse through the housing.

  • Publication number: 20050169963
    Abstract: A keratin hydrogel-filled implantable prosthetic device. One device is a breast implant for augmenting or reconstructing a human breast including an envelope containing a keratin hydrogel. One keratin hydrogel is formed from a solid precursor which forms a keratin hydrogel upon addition of water. One source of keratin is human hair. In one method, an envelope suitable for implantation and a solid keratin hydrogel precursor are provided. The solid can be in fibrous or powder form. The solid precursor can be inserted into the envelope interior. A small incision near the breast can be made and the envelope inserted into the incision. After insertion, water can be injected into the envelope interior, preferably through the incision and through a self-sealing port in the envelope. In one method, the implant is provided as a kit, with the envelope and keratin hydrogel provided. The hydrogel can be injected into the envelope either before or after insertion into the breast area.
