摘要:
A method for manufacturing a group III nitride crystal on a seed crystal in a holding vessel holding therein a melt containing a group III metal, an alkali metal and nitrogen. The manufacturing method comprises the steps of causing the seed crystal to make a contact with the melt, setting an environment of the seed crystal to a first state offset from a crystal growth condition while in a state in which said seed crystal is in contact with the melt, increasing a nitrogen concentration in the melt, and setting the environment of the seed crystal to a second state suitable for crystal growth when the nitrogen concentration of the melt has reached a concentration suitable for growing the seed crystal.

A sheet conveying device of the present invention includes a roll-up guide rotatable about a shaft. When the roll-up guide is shifted to a roll-up position where it intersects a first tray, it rolls up a sheet discharged and stores the sheet in the form of a roll. The roll-up guide allows, when shifted to a pick-up position above the body of the device, the operator of the device to pick up the rolled sheet from the roll-up guide at the operating position in front of the device. The device is easy to operate and is capable of storing a sheet in the form of a roll and allowing the roll to be safely picked up without any damage.

摘要:
The present invention provides a novel .beta.1.fwdarw.6 N-acetylglucosaminyltransferase, which forms core 2 oligosaccharide structures in O-glycans, and a novel acceptor molecule, leukosialin, CD43, for core 2 .beta.1.fwdarw.6 N-acetylglucosaminyltransferase activity. The amino acid sequences and nucleic acid sequences encoding these molecules, as well as active fragments thereof, also are disclosed. A method for isolating nucleic acid sequences encoding proteins having enzymatic activity is disclosed, using CHO cells that support replication of plasmid vectors having a polyoma virus origin of replication. A method to obtain a suitable cell line that expresses an acceptor molecule also is disclosed.
摘要:
An external preparing for skin comprising one or more than two types of 2-hydroxy benzoic acid derivative and/or salt thereof represented by the following formula: ##STR1## wherein R is an alkoxy group or alkyl group in the formula. The external preparation for the skin according to the present invention has a suppression effect on melanine generation by inhibition of tyrosinase activity. Accordingly, an excellent bleaching effect based upon the suppression of chromatosis and a high degree of safety can be obtained.
摘要:
A method is provided for detecting T-cell dysfunctions. The method includes detecting an alteration in the level of a protein regulating synthesis of the hexasaccharide NeuNAc.alpha.2.fwdarw.3Gal.beta.1.fwdarw.3(NeuNAc.alpha.2.fwdarw.3Gal.beta.1.fwdarw.4GlcNAc.beta.1.fwdarw.6)GalNAc on leukosialin of T-cells from a subject suspected of having a T-cell dysfunction compared to resting T-cells from a normal individual. The protein regulating synthesis of the hexasaccharide can be core 2 GlcNAc transferase and can be detected by either a change in its amount or activity. Also provided is a method of detecting T-cell dysfunctions which includes detecting an alteration in the level of leukosialin having the hexasaccharide NeuNAc.alpha.2.fwdarw.3Gal.beta.1.fwdarw.3(NeuNAc.alpha.2.fwdarw.3Gal.beta.1.fwdarw.4GlcNAc.beta.1.fwdarw.6)GlcNAc on T-cells from a subject suspected of having a T-cell dysfunction compared to resting T-cells from a normal individual. Kits for detecting T-cell dysfunction are provided as well.
