Abstract: The invention provides a conditioned medium that enhances the survival and/or proliferation of Schwann cells in cell culture, and a cell line useful for production of such medium. The cell line used in the invention is a differentiated NTera2/D1 (NT2) cell line.

Abstract: 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.

Abstract: A self-assembled nanometer conductive bump and a method for fabricating the bump. In the method, a multiplicity of carbon nanotubes that are coated at two ends with chemically functional groups is first provided. A substrate that is equipped with at least one bond pad on a surface is then positioned juxtaposed to the carbon nanotubes for forming a bond between the carbon nanotubes and the metal pads facilitated by a chemical affinity existed between the functional groups and the metal pad.

Abstract: A biodegradable copolymer with a core block comprising bioresorbable hydrophobic polyester segment and from 3 to 10 shell blocks comprising hydrophilic polyethylene glycol segment. The hydrophobic polyester segment and each of the hydrophilic polyethylene glycol segments are linked by a urethane linkage. A polymeric micelle composition containing the copolymer is also provided. The copolymer forms micelles when the concentration of the copolymer in a dispersing medium reaches or exceeds the critical micelle concentration. The micelles possess good drug and bioactive agent delivery characteristics and are suitable for use in drug delivery or cosmetic applications.

Abstract: The present disclosure is directed to an improved burglar alarm which is mounted on a base having a concaved space for receiving therein a ring-like magnet with an elongated resilient arm, vibratable as a result of external force, and a magnetic switch tube actuated in response to the vibrating magnet which changes either the magnet polarity or intensity of the magnetic force thereof so to produce signals to actuate a connected alarm apparatus.
