Abstract: A method of extracting proteins and peptides from nano pearl powder comprising the steps of preparing a solution containing uniformly dissolved nano pearl powder; rotating the solution to form a suspension; sifting the suspension; separating a first organic compound extract of pearl having a molecular weight more than a predetermined molecular weight and a second organic compound extract of pearl having a molecular weight less than the predetermined molecular weight from the sifted suspension respectively; and activating a first gel filter to obtain pearl proteins from the first organic compound extract of pearl, and activating a second gel filter to obtain pearl peptides from the second organic compound extract of pearl respectively.

Abstract: A bookshelf including a pair of side plates, a back plate, and a bottom plate being spaced from the back plate by a transverse opening and one or more sliding dividers each including a substantially L-shaped attachment member. The back plate is at a predetermined angle with respect to a vertical axis, the bottom plate is at the same predetermined angle with respect to a vertical axis.

Abstract: An infrared rays cauterizing structure is composed of a base, locating devices, fixed cauterizers and a hand-held cauterizer. In light of locating devices, the cauterizers can be located in proximity of a specific point of the human body without attendance of a medical personnel. The base is provided in the interior thereof with a plurality of temperature controllers and timers for regulating the treatment temperature and the treatment duration of a heater of the cauterizers. The heater is capable of bringing about a predetermined energy for treating disease or relieving pain of the specific point of the body of a patient under treatment.
