摘要:
The present invention provides a modified paramyxovirus containing a reduced amount of receptor-binding protein compared with the wild type; a method of preparing a modified paramyxovirus, comprising the following steps: (1) a step for introducing a nucleic acid that suppresses the expression of a receptor-binding protein of a paramyxovirus into an animal cell, (2) a step for infecting the paramyxovirus to the cell, and (3) a step for isolating paramyxovirus particles replicated in the cell; and a modified paramyxovirus prepared by the method of preparation mentioned above.The present invention also provides a chimera protein wherein a fusion protein of a virus has been joined or bound to a peptide that binds specifically to a cell surface marker; a nucleic acid that encodes the chimera protein; an animal cell capable of expressing the chimera protein on the cell surface thereof; a modified paramyxovirus expressing the chimera protein on the virus particle surface thereof; and a method of preparing a tissue targeting paramyxovirus, comprising: (1) a step for supplying a nucleic acid that encodes a chimera protein wherein a fusion protein of a virus has been joined or bound to a peptide that binds specifically to a cell surface marker of the target cells, (2) a step for introducing the nucleic acid supplied in (1) into an animal cell in an expressible state, and expressing the same, (3) a step for infecting a paramyxovirus to the cell, and (4) a step for isolating paramyxovirus particles replicated in the cell.

An acoustic wave filter includes a piezoelectric substrate, an IDT (interdigital transducer) formed on the piezoelectric substrate, and reflectors located at both sides of the IDT and composed of electrode fingers, at least one of the electrode fingers of at least one of the reflectors including at least one gap within a propagation path of an acoustic wave.
摘要:
A double stranded RNA having a specific nucleotide sequence is useful for treating cellular proliferative disorders. The double stranded RNA acts as siRNA against the Rad51 gene. The double stranded RNA of the present invention inhibits cellular proliferation itself. In addition, co-administration of the double stranded RNA with a chemotherapeutic agent further enhances its pharmacological effect. The combined use of the double stranded RNA with an agent having a nucleic acid synthesis-inhibitory activity or a nucleic acid-impairing activity is particularly effective.

It is intended to provide a novel polypeptide having an activity of growing vascular endothelial cells, an activity of promoting transcription form c-fos promoter, an activity of promoting transciption from VEGF promoter and/or an angiogenic activity; a polynucleotide encoding this polypeptide; the above polypeptide and/or a pharmaceutical composition containing the polypeptide for treating a disease selected from the group consisting of obstructive arteriosclerosis, Buerger's disease, peripheral vascular disorder, angina, myocardial infraction, brain infarction, ischemic heart disease and ischemic brain disease; a method of treating these diseases; and an antibacterial composition. The above problems can be solved by isolating a novel peptide having the above-described activities and a nucleotide encoding this peptide.

A package substrate includes signal pads provided on a main surface of the package substrate, footpads provided on a backside of the package substrate, and a sealing electrode provided on the main surface to surround the signal pads, the signal pads being electrically coupled to the footpads, the sealing electrode being insulated from the footpads.
摘要:
A gene transfer vector is prepared by introducing an exogenous gene into an inactivated virus envelope, through a freezing and thawing treatment or mixing with a detergent. There are also provided a pharmaceutical composition for gene therapy containing this gene transfer vector, a kit containing this gene transfer vector, and a gene transfer method employing this gene transfer vector.

摘要:
It was revealed that the intravenous administration of HMGB-1 and S100A8 promoted the healing of skin ulcer by recruiting bone marrow-derived cells to the site of skin ulcer. Furthermore, when HMGB-1 was intravenously administered to cerebral infarction model mice after creation of cerebral infarction, bone marrow-derived cells expressing nerve cell markers were detected in their brain. A marked cerebral infarct-reducing effect was observed in mice intravenously administered with HMGB-1 as compared to the control. The post-cerebral infarction survival rate was increased in the intravenous HMGB-1 administration group. The involvement of bone marrow pluripotent stem cells in the process of bone fracture healing was assessed using mice, and the result demonstrated that bone marrow-derived cells distant from the damaged site migrated to the bone fracture site to repair the damaged tissue.
摘要:
There is provided a method of fabricating an electronic device including flip-chip mounting a device chip on a substrate, and supplying solder between adjacent device chips by supplying the solder on the device chips and applying heat and pressure on the solder, and a contact angle of the device chip and the solder is greater than 90° with the solder melted.
摘要:
The invention provides a vehicle that can deliver drugs specifically to the body and a pharmaceutical preparation using the same. Disclosed is a drug delivery vehicle for cancer therapy, comprising a cationized viral envelope vector, as well as a pharmaceutical preparation comprising a drug enclosed in the vehicle. The viral envelope vector is for example HVJ-E derived from a Sendai virus, and cationization can be conducted by binding hyaluronic acid-introduced cationized gelatin or ethylene glycol-introduced cationized gelatin with the viral envelope vector. The drug to be enclosed is a nucleic acid, a vector containing a nucleic acid sequence, a protein based drug or pharmaceutical with a low-molecular compound.
