摘要:
Waste gas containing sulfur oxide (SO.sub.x) and nitrogen oxide (NO.sub.x) is mixed with an ozone-containing gas to have the value x of NO.sub.x fall in the range of 1.2 to 2.5 and thereafter brought into contact with an aqueous solution containing sulfuric acid, nitric acid and an iron compound to be deprived of SO.sub.x and NO.sub.x. To the solution with which the waste gas has been brought into contact, air or oxygen is added to effect oxidation of the part of said oxides still remaining therein in an unoxidized state and regenerate the activity of the iron compound functioning as a catalyst. Part of the solution to which the addition of air or oxygen has been made is recycled as the solution for the purpose of contact with waste gas.
摘要:

The GPR40 receptor function regulator is useful as an agent for the prophylaxis or treatment of obesity, hyperinsulinemia, type 2 diabetes and the like.
摘要:
An expression vector for the expression of an exogenous gene in an animal cell, which contains a chick .beta.-actin gene promoter and a restriction enzyme site for incorporating an exogenous gene at the downstream of said promoter and a process for expressing an exogenous gene, which comprises incorporating said exogenous gene into the expression vector at the restriction enzyme site for incorporating the exogenous gene, introducing said vector into an animal cell and culturing the obtained transformed animal cell. The expression system of the present invention can be applied to an expression of any exogenous gene and has an extremely high expression efficiency and is applicable to a wide range of host cells, and hence can sufficiently be utilized for industrial-scale production of a useful material.

In a service providing system, a live-distribution service for live-distributing contents supplied according to a reservation, and a chat service for providing the use of a chat space corresponding to the reservation for live distribution are provided. After the live distribution finishes, a communication server sends the whole or a part of the contents of chatting performed in the chat space corresponding to the reservation for the live distribution, to a personal computer. With this, even if the user of the personal computer, who supplies the contents, could not participate in a chat with a user of another personal computer while capturing the contents, for example, the user of the personal computer can check the contents of the chat later.

摘要:
A recombinant Marek's disease virus which comprises a Marek's disease virus genom and a DNA fragment incorporated therein, said DNA fragment being constructed by incorporating a promoter derived from an animal cell or an animal virus and a structural gene coding for an exogenous protein into a gene fragment derived from a Marek's disease virus, a process for preparing the same which comprises preparing a gene fragment wherein a structural gene coding for an exogenous gene is linked to the downstream of a promoter derived from an animal cell or an animal virus, incorporating said gene fragment into a BamHI - H fragment of a gene of a Marek's disease virus type I, and incorporating said fragment into a Marek's disease virus type I genome, and a multivalent live vaccine for birds comprising the same.
摘要:
In a service providing system, a live-distribution service for live-distributing contents supplied according to a reservation, and a chat service for providing the use of a chat space corresponding to the reservation for the live distribution are provided. When a personal computer and another personal computer use the live-distribution service and the chat service, they need to be authenticated by a streaming server and a communication server. For authentication, both the streaming server and the communication server use a shared password registered in a reservation data base when the live distribution is reserved.

A Kir6.2 gene-defective, non-human mammal, a mouse in particular, its tissues and cells are provided, wherein the ATP-sensitive potassium channel Kir6.2 gene, one of the subunits of KATP channels essential for insulin secretion by pancreatic &bgr;-cells, is lost from one or both of the allelic loci.
摘要:
Disclosed are (1) a method of producing D-ribose which comprises cultivating a microorganism belonging to the genus Bacillus having D-ribose producing ability in a medium, the microorganism belonging to the genus Bacillus containing a DNA sequence participating in expression of a gluconate operon which is partly or wholly modified so as to highly express the gluconate operon in the microorganism belonging to the genus Bacillus, accumulating D-ribose, and collecting D-ribose thus obtained; (2) a novel microorganism belonging to the genus Bacillus having D-ribose producing ability transformed with DNA which contains a DNA sequence participating in expression of a gluconate operon which is partly or wholly modified so as to highly express the gluconate operon in the microorganism belonging to the genus Bacillus; (3) novel DNA in which a promoter of a gluconate operon of a microorganism belonging to the genus Bacillus is modified so as to highly express said gluconate operon in the microorganism belonging to the genus Bacillus; and (4) a novel vector into which DNA is introduced in which a promoter of a gluconate operon of a microorganism belonging to the genus Bacillus is modified so as to highly express the gluconate operon in the microorganism belonging to the genus Bacillus, whereby D-ribose can be produced in stable form in large amounts.
