Abstract: An antigen-containing formulation is provided, comprising: (a) an antigen; (b) a TH1-inducing adjuvant; and (c) a sparingly soluble amino acid or a derivative thereof. The adjuvant may be, for example, monophosphoryl lipid A, 3?-de-O-acetylated monophosphoryl lipid A, derivatives thereof, or any other adjuvant that enhances an individual's TH1 response to the antigen. Suitable amino acids include tyrosine, tryptophan, derivatives thereof, and the like. Methods for using the formulation are also provided; in a particularly preferred embodiment, the formulation is used as a vaccine.

Abstract: This sports utility item is a multi-purpose cap/light combination that consists of a light system with a groove-shaped outer case body connected to a platform, which is mounted on the center top of a modified sports cap and is secured in place with velcro straps. Primarily designed for night cycling, it produces high profile illumination from a slim lightweight unit design. It has an insertable/removable head guard system which provides limited head protection from impact during both night and day cycling or other activities. The invention also functions as a versatile light system for use in other night activities such as hiking, camping, shateboarding, night fishing, and more. The light system can also be mounted on other types of headgear such as bicycle helmets when the curved platform component of the total invention is used.

Abstract: An antigen-containing formulation is provided, comprising: (a) an antigen; (b) a TH1-inducing adjuvants; and (c) a sparingly soluble amino acid or a derivative thereof. The adjuvants may be, for example, monophosphoryl lipid A, 3′-de-O-acetylated monophosphoryl lipid A, derivatives thereof, or any other adjuvants that enhances an individual's TH response to the antigen. Suitable amino acids include tyrosine, tryptophan, derivatives thereof, and the like. Methods for using the formulation are also provided; in a particularly preferred embodiment, the formulation is used as a vaccine.

Abstract: A sample filter holder for use with a microscope for holding the filter in a planar condition on the stage of the microscope so that automatic focusing of the microscope can be performed on particle samples dispersed on the filter. The holder includes a base having a well communicating with an inlet port which is connected to a suction pump. A screen assembly is positioned within the well. The screen assembly includes a disk having a screen positioned on its top surface and secured to the disk at the peripheral edge of the screen. Small bores communicate the outer surface of the screen with the well. The filter is placed on the screen and is held in a flat disposition by the suction forces.
