摘要:
Magnetically responsive therapeutic carriers comprise nanoparticles including single-domain nanoparticles comprising magnetite and having an average particle size ranging between 1 and 50 nanometers, clusters of the single-domain nanoparticles, the clusters having an average cluster size ranging between 5 and 1000 nanometers, and mixtures of the two. The single-domain nanoparticles are encapsulated with a silica coating. A silane coupling agent is bonded to the silica coating and has a specific pendant functional group capable of selectively binding with the therapeutic. Preferably, the bond between the specific pendant functional group and the therapeutic is a covalent bond. The movement of magnetically responsive nanoparticle therapeutic constructs, with concentration and extravasation/endocytosis at a target site, such as cancerous tumors, uses a controllable magnetic field generator adapted to move the therapeutic constructs in three dimensions, and is enhanced using a repetitively-varying magnetic field. A method for treating cancer comprises administering and magnetically guiding a therapeutic construct comprising paclitaxel.
摘要:
A single step milling and surface coating process allows for production of a stable dispersion of surface coated nanoparticles in an efficient manner. The process comprises providing feed particles, providing a coating agent, and generating the stable dispersion of surface coated nanoparticles by milling the feed particles in an aqueous medium containing the coating agent such that the coating agent bonds to surfaces of the feed particles as the feed particles are milled to an average particle size of less than about 100 nm.

摘要:
Barbecue meat patties of a pre-determined weight are formed by an automated process which includes the steps of providing a barbecue sauce including at least 5% of a binder, such as molasses and ketchup, mixing meat with the sauce to form barbecue meat while chilling the meat and sauce to a temperature of 28.degree. F. to 32.degree. F., forming the chilled meat and sauce into patties under a pressure of 70 to 80 psi, and gradually freezing the patties to storage temperature.
摘要:
This specification discloses a method for preparing a plurality of large blocks of glass for shipment on a transportable device (10). The method includes providing an "A" frame carrier (18) on the transportable device. A plurality of layers of shrinkable film (32) and (34) are provided which lie over and on both sides of the "A" frame carrier. A block of glass is loaded on each side of the "A" frame carrier and wrapped in the layer (34) of shrinkable film in a manner that each of the first glass blocks is substantially enclosed in the shrinkable film. The shrinkable film is shrunk about the enclosed block of glass thereby to form a sealed pouch pack (36) about the first loaded block of glass. At least a second block of glass is loaded on each side of the "A" frame carrier in association with the previously loaded blocks of glass. Each of the newly loaded blocks of glass is wrapped in the layer (32) of the shrinkable film in a manner such that each of the newly loaded glass blocks is substantially enclosed in the shrinkable film. The shrinkable film is then shrunk about the substantially enclosed glass blocks thereby to form a sealed pouch pack (40--40) about each of the newly loaded glass blocks.
