摘要:
A personal care composition comprising a hydrophilic solid, a surface active, a lipid, and an aqueous phase; wherein the lipid, hydrophilic solid, and surface active form a lipid phase; wherein the hydrophilic solid and the surface active are on the surface of the lipid, within the domain of the lipid, or both on the surface and within the domain of the lipid in the lipid phase. These compositions provide improved skin moisturization, appearance, aesthetics and skin conditioning during and/or after application, and are useful in providing improved deposition to the desired area of the skin. The present invention is further directed to a method of using the personal care composition.

A personal care composition that comprises a sunless tanning active, a surface active, a lipid, and an aqueous phase; wherein the lipid, the sunless tanning active, and the surface active form a lipid phase; wherein the sunless tanning active and the surface active are on the surface of the lipid, within the domain of the lipid, or both on the surface and within the domain of the lipid in the lipid phase. These compositions deposit sunless tanning actives on keratinous surfaces as well as provide improved skin moisturization, appearance, aesthetics and skin feel during and/or after application. The present invention is further directed to a method of using the personal care composition.

The invention is a cell aggregation device comprising a hydrogel substrate having at least one, preferably a plurality, of cell-repellant compartments recessed into the uppermost surface. Each compartment is composed of an upper cell suspension seeding chamber having an open uppermost portion and a bottom portion, and one, or more than one, lower cell aggregation recess connected to the bottom portion of the upper cell suspension seeding chamber by a port. The diameter of the port may be fully contiguous with the walls of the chambers and walls of the recesses, or the diameter of the port may be more narrow than the walls of the chamber but fully contiguous with the walls of the recesses or more narrow than both the walls of the chamber and the walls of the recesses. The upper cell suspension seeding chambers are formed and positioned to funnel the cells into the lower cell aggregation recesses through gravitational force. The aggregation recesses are formed and positioned to promote cellular aggregation by coalescing cells into a finite region of minimum gravitational energy, increasing intercellular contact and minimizing or preventing cell adherence to the substrate. A device for encapsulating aggregates of live cells is provided. The device comprises (i) a biocompatible, bio-sustainable substrate having a cell-encapsulating face composed of one or more biocompatible, bio-sustainable, spaced-apart, cell-encapsulating compartments extending therefrom and (ii) a coating layer composed of a biocompatible, bio-sustainable polymer that completely surrounds the substrate and the cell-encapsulating compartments. A method for making the device is also provided.

The invention is based on the discovery that certain membranes, which include side chains or molecular “brushes” having, for example, tertiary amino functional groups, can be used as highly effective filters to capture viruses/virus particles from liquids without removal of proteins. New methods based on this discovery include removing viruses from liquids such as blood or plasma, removing viruses from pharmaceuticals, concentrating and/or purifying viruses, e.g., for use in gene therapy, and producing recombinant viruses in new bioreactors. The invention also includes new methods of therapy or adjunct therapy for viral infections, in which a patient's blood or plasma is filtered through the membranes to remove viruses to reduce the viral load. The invention also includes new bioreactors and viral filters containing the membranes.

A glenoid prosthesis for use in total shoulder arthroplasty. The glenoid prosthesis has a concave articulating plate that can interact with the humeral component of an artificial shoulder joint, and a backing for connecting and bonding the prosthesis to the human scapula. The backing of the glenoid prosthesis can be made using hydroxyapatite, which forms a bond with human bone. The backing can further include means for connecting, such as pegs or a keel, to facilitate the connection of the glenoid prosthesis with the scapula.

A solution for spontaneous sharing between a sharer and a recipient device of a media asset reference for a media asset purchased through a media service by a user of the sharer device using a short-range wireless protocol is described. The reference includes a network resolvable identifier of a media service from which the media asset was purchased and an identifier of the media asset. The reference can also include the identity of the user who purchased and is sharing the reference thus allowing the media service to track distribution of its asset and provide an incentive based on sharing if desired when the recipient user sends a request for the media asset via the Internet to the media service including the media asset reference.

The invention provides new methods for purifying and concentrating viruses. The inventors have discovered that high molecular weight proteoglycans present in retroviral stocks are co-concentrated with the retroviruses, and can inhibit retroviral transduction. The new purification and concentration methods feature treatment of virus stock with an anionic polyelectrolyte and a cationic polyelectrolyte, followed by centrifugation. The new methods minimize the amount of proteoglycan co-precipitated with the infectious virus.
