摘要:
A biodegradable hyaluronic acid derivative comprising a modified hyaluronic acid repeating unit represented by the formula (HA)-[O(C═O)NH-M]p, wherein HA is a unit including N-acetyl-D-glucosamine and D-glucuronic acid, M is a modifying moiety containing a C2-16 hydrocarbyl group or a prepolymer, and p is an integer of 1 to 4. The biodegradable hyaluronic acid derivative when dissolved in a hydrophilic medium can form micelles and can be used to entrap a pharmaceutically active or bioactive molecule.

摘要:
An ornamental ball includes a spherical body consisting of two semi-spherical half bodies, and an inner ornamental member contained in the ball. The inner ornamental member is fixed inside the ball, having an axis shorter than the diameter of the ball and having two ends of the axis fixed at non-diametrical locations of an inner surface of the ball. Consequently, the ball rotates irregularly owning to the gravitational impact of the ornamental member.

A simple detachable illumination lamp tube includes a tube unit, a heat-dissipating unit, a light-emitting unit, a support unit and a lateral cover unit. The tube unit has a light-permitting hollow tube. The heat-dissipating unit has a heat-dissipating substrate received in the light-permitting hollow tube. The heat-dissipating substrate has two opposite lateral sides contacting the inner surface of the light-permitting hollow tube. The light-emitting unit has a plurality of strip light-emitting modules received in the light-permitting hollow tube. The strip light-emitting modules are disposed on the heat-dissipating substrate and electrically connected in sequence. The support unit has a plurality of support elements received in the light-permitting hollow tube and disposed between a bottom side of the heat-dissipating substrate and the inner surface of the light-permitting hollow tube. The lateral cover unit has two lateral covers installed on two ends of the light-permitting hollow tube.
