Abstract: A continuous positive airway pressure (CPAP) machine storage stand. The CPAP machine storage stand includes a base having a lip extending perpendicularly away from a periphery of the base defining an interior portion of the base. The interior portion can receive a CPAP machine therein. A U-shaped frame having a first end and a second end is hingedly affixed to opposing sides of the lip at the first and second ends thereof. The U-shaped frame can selectively move between a deployed position and a collapsed position, wherein the U-shaped frame rests flush against the base within the interior portion when in the collapsed position.

Abstract: A radioimmunoassay method for the determination of triiodothyronine in human and animal fluids and tissues, particularly in serum. The method involves the separation of triiodothyronine from its binding proteins using a dextran gel column followed by competitive binding between the freed triiodothyronine and radioactive labeled triiodothyronine which remain bound to the gel column for triiodothyronine-specific anti-serum. Bound and free labeled triiodothyronine are separated by washing the column and their ratio is determined based on the amount of radioactivity remaining in the column to that originally added thereto.
