摘要:
The present invention relates to a therapeutic agent or prophylactic agent for a disease requiring enhancement of nerve growth factor (NGF) production upon treatment or prevention, an enhancing agent for nerve growth factor production, and a food, beverage or feed for enhancing nerve growth factor production, characterized in that each comprises as an effective ingredient a compound selected from the group consisting of soyasaponin compounds, soyasapogenin compounds, glycyrrhizin and salts thereof. In addition, the present invention relates to a novel soyasaponin compound and a novel soyasapogenin compound, having an action for enhancement of NGF production.
摘要:
A promoter, an intron and a terminator by which a useful foreign gene can be efficiently expressed in algae and which are thus useful in breeding algae using genetic engineering techniques.
摘要:
The present invention is a method for inducing cytotoxic T cell having an antigen-specific cytotoxic activity, a method for maintaining the cell, a method for continuously culturing the cell or a method for expanding the cell, comprising the step of culturing a cytotoxic T cell in the presence of at least one substance selected from the group consisting of (A) a substance having a binding activity to CD44; (B) a substance capable of regulating a signal emitted by binding a CD44 ligand to CD44; (C) a substance capable of inhibiting binding of a growth factor to a growth factor receptor; (D) a substance capable of regulating a signal emitted by binding of a growth factor to a growth factor receptor; and (E) fibronectin, a fragment thereof or a mixture thereof.
摘要:

摘要:
Novel physiologically active substances useful as remedies for fungal infection or immunologic diseases, which are physiologically active substances TKR2449 represented by general formula (A): wherein R1, R2 and R3 are the same or different and each represents hydrogen or C1-4 alkyl; and R4 represents linear or branched C1-8 alkyl or alkenyl.
摘要:
The present invention provides an agent for maintaining homeostasis in a living body, food, beverage or feed, utilizing a fucoidan, a degradation product thereof or a salt thereof, having an action for maintaining homeostasis in a living body. The present invention also provides a fucoidan and a marine alga extract with reduced color, reduced bitterness and reduced iodine content, and improved flavor and taste with freshness, a food, beverage, seasoning, feed, cosmetics or medicament, comprising the fucoidan and/or the marine alga extract, and processes for efficiently manufacturing them.
摘要:
A method of highly sensitively and specifically amplifying a target nucleic acid in a sample by using a chimeric oligonucleotide primer having a ribonucleotide provided at the 3'-terminus or in the 3'-terminal side, an endoribonuclease and a DNA polymerase having a chain transfer activity, i.e., an isothermal and chimeric primer-initiated amplification of nucleic acids (ICAN) method; a method of detecting an amplified fragment obtained by using the above method; a process for producing a target nucleic acid by using the above amplification method; and chimeric oligonucleotide primers to be used in these methods.
摘要:
A polypeptide having an RNaseH activity and being highly useful in gene engineering; a gene encoding this polypeptide; and a genetic engineering process for producing the polypeptide.
摘要:
A method of selecting a marker gene which is useful in identifying cancer; a method of identifying cancer by using this gene; a method of detecting cancer, a kit to be used in the identification or detection method; and a DNA array holding the above gene. Thus, it is possible to obtain a gene which shows a change in the expression dose independently from a gene showing a change in the expression specifically at the proliferation of cells and specifically to each cancer sample. Use of this gene makes it possible to conveniently and quickly identify or detect cancer withou resort to any surgical operations, thereby contributing to the diagnonis and treatment of cancer, etc.
