摘要:
In a semiconductor device having a thin insulating film of 300 .ANG. or less in thickness on which a conductive layer is provided, the conductive layer is connected to the semiconductor substrate at a position outside the active regions. With such a structure, negative charges accumulated on the conductive layer during the reactive ion etching or ion implantation process can be easily discharged to the semiconductor substrate to prevent a dielectric breakdown of the thin insulating film. In the embodiment, the thin insulating film is a dielectric film of a MOS storage capacitor of a one-transistor type memory cell and the conductive layer is the upper electrode of the MOS capacitor.

摘要:
Disclosed is a mutant protein having an altered fibroblast growth factor receptor specificity, which is produced by deleting one or more amino acid residues from the N-terminus of the amino acid sequence of naturally secreted fibroblast growth factor 18. The protein mutant can be used in a pharmaceutical composition for regulating hair regeneration or growth or a pharmaceutical composition for regulating bone or cartilage formation.

A heparin-binding protein having covalently bonded heparan sulfate sugar chains within its molecule is produced by ligating a cDNA encoding a peptide which can be modified with heparan sulfate sugar chains selectively to a cDNA encoding a heparin-binding protein and producing in an animal cell the gene product of the resultant ligated cDNA. This heparan sulfate sugar chain-modified heparin-binding protein is functionalized by covalently bonding thereto glycosaminoglycan sugar chains containing little chondroitin sulfate. For example, this heparin-binding protein is excellent in stabilities, such as thermostability, acid resistance, alkali resistance and in vivo stability. Further, the heparan sulfate sugar chain-modified heparin-binding protein is effective in cell proliferation and tissue regeneration, and has effect of regulating the physiological functions of FGFs. Thus, this heparin-binding protein is extremely useful as a medicine for preventing or treating various FGF-related diseases.

A data terminal, a data distributing system, and an Internet telephoning system are provided where desired data such as advertisements can selectively be determined and used for enjoying its relevant services. The data terminal receives a summary of service data from a data provider apparatus over the Internet, and if desired, demands the data provider apparatus to provide the service data over the Internet. The service data from the data provider apparatus may selectively be received in at least one of an audio form, a text form, and a video form at the data terminal. The service data may be advertisement data, commercial product data, and entertainment data such as music, movies, and games. The entertainment data may selectively be presented as at least one of the title, the artist name, the cost, and a trial sample piece of the content.

摘要:
The present invention prepared a non-human animal in which Fgf18 gene was knocked out in a keratin-5 positive cell-specific manner using a Cre-loxP system; it provides a non-human model animal in which FGF18 expression has been inhibited in a hair follicle-specific manner to shorten the telogen phase of hair growth cycle. The non-human model animal is useful in studying hair follicles and skin, particularly hair growth occurring cyclically in hair follicle cells, and is applicable to the development of and screening for novel drugs against hair follicle or skin disorders.
