Publication number: 20120214193Abstract: An object of the present invention is to provide a method for increasing the change in the fluorescent intensity as emitted from potential-sensitive fluorochromes depending on a potential or ionic strength change. Another object of the present invention is to measure the changes in the activity potentials of ES cell- or iPS cell-derived cardiomyocytes that have heretofore been impossible to measure. The present inventors screened a variety of substances and found that vitamin E has an action for increasing the sensitivity of potential-sensitive fluorochromes whereas cholesterol has an action for enhancing the fluorescent intensity of potential-sensitive fluorochromes. In addition, it has become clear that these substances can be combined in such a way that the sensitivity of a potential-sensitive fluorochrome is increased by vitamin E while at the same time its absolute fluorescent intensity is enhanced by cholesterol.Type: ApplicationFiled: October 29, 2010Publication date: August 23, 2012Applicant: Keio UniversityInventors: Fumiyuki Hattori, Keiichi Fukuda, Yu-suke Satoh

Publication number: 20100189699Abstract: The object of the present invention is to improve the post-transplantation engraftment rate of cardiomyocytes that have been purified to such an extent that they are free from non-cardiomyocytes and any components derived from other species.

Publication number: 20100145441Abstract: An objective of the present invention is to analyze the function of anti-angiogenic factors in cardiac valves or such to elucidate the developmental mechanism of angiogenesis-induced diseases. A more specific objective is to provide therapeutic agents for angiogenesis-induced diseases such as valvular heart disease, and methods of efficiently screening for the therapeutic agents. The present inventors discovered that chondromodulin-I was markedly expressed in cardiac valves, and plays an important role in maintaining normal functions of the valves by preventing angiogenesis, thickening, and calcification which lead to valvular heart diseases. Chondromodulin-I proteins and substances that activate the expression or function of the proteins are expected to have therapeutic effects against angiogenesis-induced diseases.Type: ApplicationFiled: September 15, 2006Publication date: June 10, 2010Inventors: Keiichi Fukuda, Yuji Hiraki

Publication number: 20090242548Abstract: The present invention relates to a tape heater including: at least one flexible fabric base formed from a heat-resistant thread, the at least one flexible fabric base including a first fabric base part and a second fabric base part; and a heater member, in which the heater member is interposed between the first fabric base part and the second fabric base pan. Since the heater member is interposed between the fabric base(s), the tape heater of the present invention exhibits superior flexibility and stretchability and is superior in easily being wrapped around a pipe, as well as reliably protecting the heater member. Further, tape heaters can be continually manufactured, so long as weaving or knitting of the fabric base(s) is caused to proceed while the heater member is interposed between the fabric base(s), to thus join the fabric base(s). Hence, enhancement of production efficiency and prevention of an increase in production cost can be attained.Type: ApplicationFiled: March 25, 2009Publication date: October 1, 2009Applicants: NICHIAS CORPORATION, THERMOS CORPORATION, HOKURIKU FIBER GLASS COMPANY, LIMITEDInventors: Kenji Iida, Keiichi Fukuda, Akira Sasaki, Daisaku Seki, Emico Taguchi, Masayuki Kitamura
