Abstract: Disclosed are particles for delivering cytokinese, such as IL-12, for the treatment of cancer. The particles comprise cytokines non-covalently bound to liposomes, where the liposomes are coated with polyelectrolytes.

Abstract: Apparatuses and methods to mask identification information to create billing mechanisms in an online listing system are disclosed. In one embodiment, a computer-implemented method of operating an online listing system includes determining an identity of a user based on an identifier entered by the user that uniquely identified the user; and capturing call history information when routing a proxy telephone number from the user (e.g., a renter, a buyer, a prospective buyer, a mortgagor, etc.) to a lister (e.g., a landlord, a seller, a rental manager, a mortgagee, etc.). The identifier may be the proxy telephone number and/or a code entered after dialing the proxy telephone number. The proxy telephone number may be converted to an actual telephone number prior to routing the proxy telephone number to the lister.

Abstract: A footwear system for animals, particularly the front legs of a canine, that includes protective coverings adapted for both well and sore or injured legs and can be configured for single-leg and two-leg uses. An optional adjustable neck strap assembly provides for a comfortable and snug fit of the protective coverings to the legs and around the shoulder of the dog. A unique cuff assembly facilitates holding the protective covering one or the other of the front legs of the dog while minimizing opportunities for the dog to chew on or remove the footwear.

Abstract: A connector element for a rod and connector construction toy set of the type enabling a lateral snap-in assembly of rod elements into sockets of the connector is formed of two hingedly connected connector half sections. Each connector half section is formed along one edge with one male and one female hinge element such that two identical connector half sections can be joined together, by a snap-together action of the hinge elements, to form a connector element with one half pivotally movable relative to the other half. Each connector half section is formed with a plurality of rod-engaging sockets accommodating the construction of complex, three-dimensional structures. Advantageously, the two connector half sections are of identical construction, such that both components may be formed of a single mold configuration.
