Patent number: 10442843Abstract: It has been believed that promoting the assembly of polysomes composed of many ribosomes attached to mRNA is very effective for highly efficient protein synthesis. However, the mechanism for p180 protein's capability of promoting polysome formation has been yet to be elucidated. The inventors of the present application newly discovered SF3b4 protein as a protein that specifically interacts with the coiled-coil domain of p180 protein, a responsible region for its capability of promoting polysome formation, and which is capable of promoting mRNA localization to an endoplasmic reticulum (ER). The inventors also found that, in cells capable of highly expressing both p180 protein and a protein promoting mRNA localization to an endoplasmic reticulum (ER) (e.g., SF3b4 protein), the mRNA localization to the endoplasmic reticulum can be significantly elevated so that the secretory capacity in cultured cells can be enhanced.Type: GrantFiled: August 24, 2017Date of Patent: October 15, 2019Assignee: NIPPI, INCORPORATEDInventors: Tomonori Ueno, Yuki Taga, Kiyoko Goto, Yuko Kaku

Patent number: 10442885Abstract: A process for producing a polyurethane-coated conduit element includes mixing a) a mixture of aromatic and aliphatic polyisocyanate with, b) at least one polymeric compound having at least two hydrogen atoms which are reactive toward isocyanate, c) at least one chain extender, d) a catalyst, and e) optionally at least one other auxiliary, additive, or both, to form a reaction mixture; applying the reaction mixture to a conduit element; and allowing the reaction mixture to react to form a polyurethane layer. The polyurethane-coating conduit element is suitable for maritime applications in the oil and gas industry, which polyurethane has improved hydrolysis stability at high temperatures and nevertheless satisfies the high mechanical demands in the oil and gas industry.Type: GrantFiled: December 11, 2013Date of Patent: October 15, 2019Assignee: BASF SEInventors: Andre Kamm, Julia Liese, Karl Gust

Patent number: 10442886Abstract: Provided is a mechanochromic resin by which a stress applied to a material can be visualized in real time, and a mechanochromic luminescent material that is used in the synthesis of the mechanochromic resin. Stress can be visualized in real time by means of a mechanochromic luminescent material represented by formula (1) or formula (2) and a mechanochromic resin obtained by crosslinking the mechanochromic luminescent material. [Chemical formula 1] (In the formula, Y1 and Y2 each denote a substituent group that inhibits aggregation of the mechanochromic luminescent material represented by formula (1), and Y1 and Y2 may be same as or different from each other. Z1 and Z2 each denote a polymerizable group, and may be same as or different from each other.) [Chemical formula 2] (In the formula, Y1 and Y2 each denote a substituent group that inhibits aggregation of the mechanochromic luminescent material represented by formula (2), and Y1 and Y2 may be same as or different from each other.Type: GrantFiled: November 16, 2015Date of Patent: October 15, 2019Assignee: Japan Science and Technology AgencyInventors: Hiroshi Yabu, Yuta Saito, Shohei Saito, Shigehiro Yamaguchi, Shunpei Nobusue
