Abstract: The present invention relates to a controlled drug release system in which a certain ratio or retinoic acid is incorporated into a microsphere comprising biodegradable polymer and amphoteric block copolymer having both hydrophilic and hydrophobic groups.

Abstract: The present invention relates to a zebrafish HuC promoter with its 5′-flanking region which directs the neuron-specific expression of structural genes, a transgenic animal that shows the neuron-specific expression of GFP (green fluorescence protein) under the regulation of the HuC promoter, and a method for screening neurogenesis mutants in zebrafish by use of the transgenic animal. The HuC promoter with its 5′-flanking region can be used in the study of the regulatory mechanism responsible for the differentiation of the nervous system. Additionally, the HuCP-GFP transgenic zebrafish enables the direct identification of neurogenesis and axonogenesis, as well as being a valuable tool for isolating and analyzing neurogenesis mutants in live zebrafish with ease.

Abstract: A masking film adhering method for transporting smoothly and accurately a masking film tape to which a wafer is stuck to the cutting location where the masking film is to be cut. The wafer is stuck onto the masking film tape by passing the masking film tape and the wafer through upper and lower adhesive rollers. The separation of the masking film tape is then increased from a cutting table so that the masking film tape having the wafer stuck thereon may not become adhered to the cutting table, by moving the upper adhesive roller upwardly when the wafer completely passes through the adhesive roller. After the masking film is transported to a cutting location, maintaining a predetermined distance between the masking film and the cutting table, the masking film tape is cut along the shape of the wafer. Sagging of the masking film due to the weight of the wafer is prevented to avoid the masking film tape adhesion to the cutting table.
