Abstract: Provided are a cold storage method and a cold storage liquid that are suitable for non-freezing refrigerated storage of human or animal stem cells such as iPS cells or embryos in a non-frozen state. According to an embodiment, the non-freezing refrigerated storage liquid is: a mixture liquid (HTM?, HTMx2c13), in which MEM-alpha (Minimum Essential Medium Eagle (MEM) Alpha Modification) is mixed with a UW solution (UW_sln; BELZER UW (registered trademark) COLD STORAGE SOLUTION), or a modified UW solution (polymer component being changed to PVA), are mixed in a ratio of about 1/1 to 1/2; or a storage liquid having a composition equivalent to the mixture liquid, especially in respect of concentrations of potassium ions and sodium ions. And, arousal period(s) of maintaining a temperature of 30° C. to 37° C. is inserted at each of two to five days, into a non-freezing refrigerated storage period, which is made at 2° C. to 8° C. for 2 to 10 days or 4 to 20 days.

Abstract: A non-freezing refrigerated storage liquid for stem cells such as iPS cells, according to an embodiment, comprises: potassium ion species in a range of 30 to 80 mmoL/L; sodium ion species in a range of 30 to 80 mmoL/L, wherein ion-based molar ratio of sodium ion species to potassium ion species (ratio ofNa+ to K+) is in a range of 0.5 to 1.3; trolox or its analog at a concentration of 1 to 8 mM; adenine or a salt or derivative thereof at a concentration of 0.1 to 4.2 mM; all of or all but one, two or three of essential amino acids, total content of which is 50 to 200 mg; and non-essential amino acids, total content of which is 50 to 200 mg/L.

Abstract: The invention provides a gene specifically expressed in haploid cells of the testis. The gene is located on the X-chromosome of a mammal, is specifically expressed in haploid cells of the testis, has a base sequence which can hybridize, under stringent conditions, with DNA including a base sequence in SEQ ID NO: 1, and encodes a protein including an amino acid sequence having a homology of at least 25% with an amino acid sequence encoded by the drosophila gcl gene.

Abstract: Method of breeding poultry for food wherein they are fed with specific feedstuff, particularly at their age of from 10 to 60 days, in order to improve the meat quality so that they have meager fat and much meat in the body; the feedstuff contains either protein which contains both iodide (i.e. sodium iodide) and iodate (i.e. sodium iodate) in combination, or protein with which iodine is combined; the ratio of the iodide-and-iodate-containing protein to the feedstuff is from 1 to 3500 ppm, and the ratio of iodine-combined protein to the feedstuff is from 1 to 350 ppm, respectively as iodine concentration.

Abstract: A metal heating furnace for heating slabs, billets or blooms prior to their hot rolling. Full use to thermal energy can be ensured and the workpieces can be uniformly heated to a desired rolling temperature.
