Abstract: An aircraft includes an airframe defining a first enclosed space, an engine bay disposed within the first enclosed space, and a cooling system. The engine bay includes a firebox defining a second enclosed space and an engine disposed at least partially within the second enclosed space. The cooling system is configured to selectively fluidly couple the first enclosed space with the second enclosed space.

Abstract: The invention is a non-hydrated, keratin wound dressing film comprising a fraction of keratins isolated from a solution of extracted keratins. Said fraction enables the formation of film with greater flexibility that can be achieved in film made from the unfractionated keratin extract. Also disclosed is a process of forming wound dressings and a method of obtaining said keratin fraction from an extract of human hair or other keratin raw materials.

Abstract: A wound care dressing that combines a sodium alginate hydrogel spread and a calcium solution spray to create a transparent membrane over damaged skin eliminating the need for a secondary dressing. The calcium dissolved in alcohol displaces sodium from the hydrogel spread, resulting in the formation of the membrane. The membrane decreases healing time by fostering hemostasis, a moist wound healing environment and absorption of exudate and blood from the wound. The membrane also provides an immediate cooling effect for the damaged skin. Once the wound is cleaned, the user applies the hydrogel and covers it with a mist of spray which creates a film layer. The membrane is transparent and flexible such that the skin surface is still visible and the membrane will not be dislodged as the skin is manipulated. The dried surface of the membrane is not tacky, eliminating the need for a secondary dressing.

Abstract: The present invention provides a hair graft comprising (a) tissue engineered skin comprising a tissue engineered epidermal layer, a tissue engineered dermal layer, and hair follicle progenitor cells and (b) a scaffold. The invention also provides methods of making and using the hair grafts of the present invention.

Abstract: The present invention is a hair graft derived from a plucked hair comprising a plucked hair having adhered epidermal stem cells and associated follicular dermal cells. The present invention also includes methods of making a hair graft, methods of implanting a hair graft and methods of identifying inductive follicular dermal cells.

Abstract: The present invention relates to an improved scaffold which is constructed to mimic the architecture of the native hair follicle. The present invention also relates to the use of specific compositions and methods of manufacture to produce scaffolds that combine biocompatibility with the desired rates of bioabsorption. In another embodiment, the present invention relates to a process for manufacturing a biomimetic hair follicle graft and a method for seeding the graft with cells and implanting the graft into the skin where the growth of a new hair shaft is desired. A further embodiment of the present invention relates to a method for hair multiplication in which cells are multiplied in culture and aliquoted into a multitude of bioabsorbable scaffolds in combination with cultured keratinocytes or other allogenic cells.

Abstract: The present invention provides a filamentary structure for the introduction of agents into a living host, comprising a filament comprising a solid core and a porous sheath which coats at least a portion of the solid core. When the filamentary structure is to be permanently implanted into a living host, both the solid core and the porous sheath are bioabsorbable. When the filamentary structure is to be temporarily implanted into the skin of a living host to deliver agents, such as cells, therein, the porous sheath is preferably bioabsorbable but the core need only be biocompatable, not bioabsorabable. The devices and methods of the present invention enable one to regenerate hair follicles, to introduce genetically altered cells or encapsulated cells to a living host transdermally, to regenerate bones, and to deliver drugs transdermally.

Abstract: A method of producing flat glass in which foam which appears on the surface of molten glass melted using oxy-fuel burners is dispersed by directing a diffuse, luminescent flame onto the surface of the glass carrying the foam.
