Creation of cancer cell specific oligonucleotide therapeutics

NEXT
PREV
Features

Focusing our reseach interest mostly on the recognition and complexation behavior control of bioplymrs, such as DNA/RNA, proteines and so on. Another topics are reaction control based on molecular recognition phenomena in both ground and electronically excited states, we are pursuing mechanistic and synthetic studies on asymmetric photochemistry with supramolecular biopolymers as chiral reaction fields.

Surface scientific approach for developments in fuel cell's catalysts

NEXT
PREV
Features

From catalytic perspective, molecular-level understanding of surface phenomena occurring at nano-sized metal (alloy) particle surfaces is a key for developing highly active and durable catalysts. Our experimental approach for studying catalysis is preparations of well-defined metals or alloy surfaces by using ultra-high vacuum (UHV) and molecular-beam-epitaxy (MBE) techniques. We routinely use UHV-MBE, surface vibrational spectroscopy (IR, Raman), scanning probe microscopy (SPM), electron spectroscopy (XPS), electrochemical (EC) voltammetry, gas-chromatography (GC) etc., and try to clarify the solid surface phenomena on atomic, molecular-levels. We believe our research results directly link to future eco-friendly society.

Development of new methods and apparatus for industrial elemental analysis

NEXT
PREV
Features

A goal of our research is to develop new instrumental methods in quantitative elemental analysis. We have suggested a new analytical method enabling trace elements at a few ppm level to be directly determined. We now study analytical applications of a low-pressure laser induced plasma as well as a glow discharge plasma associated with laser ablation, in order to carry out rapid analysis for the process control in material industries and for selection of scrapped materials.

Targeted Application(s)/Industry

Industry: We have already conducted cooperative research on industrial analyses with several metal-making companies as well as the iron and steel institute of Japan. We also hope cooperative works on practical analysis in various manufacturing fields.

PREV
Features

PET and SPECT have very high sensitivity to detect molecule by means of radiation detection, and are considered to be excellent tools for molecular imaging. We are studying and developing data analysis techniques for PET and SPECT data. Using our approaches, we can analyze data in quantitative manner, and obtain physiological functions in living organism.

Targeted Application(s)/Industry

Pharmaceutical companies who are interested in using PET to evaluate efficacy of new drug. Companies which are related to medical informatics, medical equipments.

Support for Succession of Traditional Performing Arts which Utilized Motion Capture System

NEXT
PREV
Features

I utilize the newest motion capture system and am supporting succession of traditional performing arts or folk performing arts. I carried out motion capture of various dances until now. The data obtained by motion capture is reproduced by 3DCG and animation, etc. This is a modern and attractive image.

Targeted Application(s)/Industry

These works are helpful in order to support the succession to children. And it becomes contents effective also for regional improvement, such as the tourist industry.

Improvement of Seed Production by Using Reproductive Trait in Crops, Especially, Rice and Cruciferous Crops

NEXT
PREV
Features

Crops are important for food, environment recovery, energy production, and amenity activity for human being. For improvement of crop seed production, the breeding of crops having environmental stress, is important. Especially the developmental stage from pollination to fertilization is quite weak for these environmental stresses. Thus, by breeding of reproductive trait, we will establish the high productivity and quality of crop seeds. From our research, we found several stress-tolerant genes. We already started the research by both basic and applied level.

Targeted Application(s)/Industry

For application, we evaluated by taking prize for application in 2001. And our basic data has been published in international Journal, "Nature" and "Science". If anyone is interested in these genes, we hope to conduct to collaborative research for establishing the useful breeding lines.

Development of Wearable Motion Measurement System for Motor Rehabilitation and Healthcare

NEXT
PREV
Features

In order to realize wealthy and vibrant local communities, it is desired that people in the community are healthy. However, the amount of the daily activity decreases as they get older, which increases the risks of the fall by weakened lower limb muscles and of the cerebrovascular disease, and so on. Therefore, for the elderly people, there is increased need of the walking training and the movement assistance in daily life, and of the rehabilitation aid.
In this study, focusing on the motor function of the lower limbs that is important for independent activities of daily living and that relates to the health maintenance, development of assistive technologies for decreased gait ability or for dysfunction of lower limbs are performed based on the technologies of electronics and signal processing. Especially, the wearable sensor system using gyroscopes and accelerometers are developed to measure kinetic information, and then the evaluation system for the gait ability and the lower limbs motor function is developed in this study.

Targeted Application(s)/Industry

The goal of this study is to realize simple and convenient measurement and accumulation of various information of gait, to visualize the obtained data for determination of training effect and evaluation of motor function, and to provide appropriate training program for each subject.
