摘要:
The invention involves a papilloma pseudovirus that can induce immune response after oral intake as well as its preparation. It is characterized in that HPV or BPV pseudovirus are made by disrupting HPV-VLP or BPV-VLP, mixing them with plasmids (plasmids or DNA vaccine), and reassembling them into the pseudoviruses (VLPs with plasmids inside). Oral administration of the pseudoviruses will result in delivery to mucosal and systemic lymphoid tissues and induce immune responses for disease prevention and treatment. The pseudovirus induces stronger immune response than DNA vaccines. Additionally, the pseudovirus can be applied in gene therapy by bringing the therapeutic genes into lymphoid tissues in the human body.

A heat spreader for an LED can include a thermally conductive and optically transparent member. The bottom side of the heat spreader can be configured to attach to a light emitting side of the LED. The top and/or bottom surface of the heat spreader can have a phosphor layer formed thereon. The heat spreader can be configured to conduct heat from the LED to a package. The heat spreader can be configured to conduct heat from the phosphors to the package. By facilitating the removal of heat from the LED and phosphors, more current can be used to drive the LED. The use of more current facilitates the construction of a brighter LED, which can be used in applications such as flashlights, displays, and general illumination. By facilitating the removal of heat from the phosphors, desired colors can be better provided.

A substrate for an LED assembly can have a plurality of cups formed therein. At least one cup can be formed within another cup. The cups can be co-axial with respect to one another, for example. A machined surface of the substrate can enhance reflectivity of the LED assembly. A transparent and/or non-global solder mask can enhance reflectivity of the LED assembly. A transparent ring can enhance reflectivity of the LED assembly. By enhancing reflectivity of the LED assembly, the brightness of the LED assembly can be increased. Brighter LED assemblies can be used in applications such as flashlights, displays, and general illumination.

A cooling device including a thermally conductive body with a first mating surface, a first solder wettable material disposed in a pattern at a portion of the first mating surface, and a reflowable solder material disposed at the first mating surface. A portion of the solder material is configured to be capable of contacting an adjacently disposed second mating surface, and when melted, to form a single flow front through a bond line gap between the first mating surface of the cooling device and the second mating surface of, for example, a thermal component.A mating surface of the cooling device is positioned adjacent to a mating surface of a thermal component and the solder material is heated at least to its melting point. The solder material is maintained in a molten state until it has flowed into and substantially filled a bond line gap between the mating surface of the cooling device and the mating surface of the thermal component, and then cooled below its melting point, physically and/or thermally coupling the cooling device and the thermal component.
