[ABC transporter]
Regulation of ABC Transporters in Colorectal CancerFeaturesColorectal cancer (CRC) is one of the most common types of cancer worldwide. Surgical resection is the only curative treatment available for primary CRC. We determined the gene expression profiles for ATP binding cassette (ABC) transporters by RNA sequencing in matched colon cancer and normal colon tissue specimens in order to provide insight into the regulatory mechanisms underlying expression of transporters related to colon carcinogenesis. The expression of ABCC3 was repressed by Wnt signaling pathway, suggesting downregulation of ABCC3 might contribute oncogenesis. Targeted Application(s)/IndustryRecently, we easily obtain comprehensive data including transcriptome and other omics data. These data are expected to help find a target for drug development, expecting that pharmaceutical industry interpret and extract new knowledge from them. |
[acceleration sensor]
Assessment of Physical Activities Using Wearable SensorsFeaturesMaintaining appropriate amount of physical activity is essential for health and disease prevention. Gait is the most common type of physical activity in everyday life. Monitoring the amount of physical activity in everyday lives may benefit mainly those who are at threat of metabolic syndrome and overweight. Towards better estimation of the amount of physical activity utilizing wearable sensors, we focused on taking running and walking economy into account. The relationship between step length and oxygen uptake was first determined. Step length estimation with moderate accuracy was accomplished using acceleration signals during walking. Step length was then taken into energy expenditure calculation as one of the variables. Targeted Application(s)/IndustryTogether with the basic version of the current locomotion monitoring system capable of counting staircase climbing up & down, we managed to upgrade our locomotion monitoring system into 3 dimensional. |

[acoustic power]
Understanding and application of thermoacoustic phenomenaFeaturesAcoustic oscillations of a gas column in narrow flow channels can lead to various thermal phenomena such as production and amplification of acoustic power from heat and generation of low temperatures.

Targeted Application(s)/IndustryAcoustic prime mover can use various heat sources like industrial waste heat and sunlight. Acoustic cooler is a Helium-gas based heat pump that needs no Freon gases as a coolant. |
[Acoustic reconance]
Dry-Contact Ultrasonic TechniqueFeaturesA new dry-contact technique for transduction of broadband, high-frequency ultrasound via a solid layer inserted between water and the sample, whereat the pressure of about 0.1 MPa is applied at the layer/sample interface by evacuating air between them, has been developed. Based on the technique, acoustic imaging of an electronic package is realized under the dry environment (Fig. 1). Typically, the polymer films are used as the intermediate layer for water protection of the sample, and by utilizing the acoustic resonance phenomenon among water, film and the sample, higher quality acoustic image of the testing sample than that for the water immersion case can be recorded without getting the sample wet (Fig. 2). Moreover, thin materials, e.g., polymer film (Fig. 3), etc. can be characterized by analyzing the acoustic resonance phenomenon among the three media. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry. |

[adsorption/desorption]
Selective recovery of tocotrienol from vegetable oils using ion-exchange resinsFeaturesTocotrienol, one of vitamin E, has recovered by the conventional method with molecular distillation from deodrizer distillate discharged from the oil refining processes. However, tocotrienol easily loses its activity due to its low thermal stability, so that its recovery ratio and purity were extremely low. We proposed a novel method to selectively recover tocotrienol by adsorption/desorption using anion-exchange resin at 50 degree C. Tocotrienol is retained on the resin by ion-exchange reaction, and then released and recoverd from the resin by other ion-exchange reaction. Prior to the adsorption/desorption, free fatty acid, a major component of the feed, should be removed by esterification using cation-exchange resin at 50 degree C. Targeted Application(s)/IndustryThis innovative technology succeeds in solving the serious problems in the current tocotrienol production, the large weight loss due to the thermal decomposition and large amount of remaining impurities. This technology applies to the production of not only tocotrienol but also tocopherol as bioactive compounds s in food chemicals. Graduate School of Engineering
