Speed, Accuracy, and Low Cost Vital to Treating Trypanosomiasis and Tuberculosis
Finding candidate therapeutic agents for infectious diseases prevalent in Southeast AsiaDengue fever is a viral disease spread by mosquitoes that infects 50 million people living in the tropics every year, with about
200,000 fatalities, but no effective therapies have yet been established. However, whenever someone is infected by a disease
agent, his or her body makes proteins called antibodies. The key role of those antibodies is to control the symptoms of the
disease and cure the patient. We are conducting research that involves taking antibodies from dengue fever patients that seem
to be useful against the disease, and attempting to use them as medicine. At the same time, we are conducting similar research
for influenza, which is a worldwide problem, and for the botulinum toxin, which is a problem in Thailand. We are also searching
microorganisms prevalent in Thailand for compounds that are effective as a dengue fever treatment.
Conducting experiments to develop new drugs following the successful creation of antibodiesWe have succeeded in creating many antibodies against the dengue virus,
influenza virus and botulinum toxin. Many of those antibodies appear to
be potentially effective as therapeutic agents. Next, we will perform more
detailed evaluations, aiming for the development of new drugs.

Preventing spread of infection through fast and accurate diagnosisTuberculosis, one of the most serious infectious diseases in Zambia, is a zoonotic disease that is expected to spread
because it has developed resistance to existing therapies. Another major disease is malaria, but misdiagnosis of
trypanosomiasis and other similar ailments as malaria often leads to death as a consequence of failure to provide
appropriate treatment. Early diagnosis and appropriate treatment is essential to preventing the
spread of these diseases. For this project, we are seeking to adapt highly sensitive, speedy and
low-cost diagnosis systems developed largely in Japan to the diagnosis of tuberculosis and
trypanosomiasis, and at the same time develop drugs to treat trypanosomiasis.
Successful development of diagnostic techniques and discovery of many potential therapeutic drugsOur research led not only to the successful development of speedy techniques for diagnosing
tuberculosis and trypanosomiasis that are practical for use at local inspection stations, but also to the synthesis of over 300
candidate substances with potential to become therapeutic drugs, and we are now assessing their effectiveness. We plan to
transfer these outcomes to Zambia, and improve its research and development capabilities.

The period of research in South Africa was highly fulfilling, and is now becoming a fond memory. I am convinced that the contribution we made to S&T diplomacy and the firm links we built with collaborating researchers and policy workers will provide a solid foundation for subsequent stages. It would be good to go back for a visit during
the spring when the jacaranda trees are in bloom, coloring the city purple-blue.

We faced many difficulties, including field studies in mountainous areas at elevations over 5000m. It was the extent of the collaboration with Bhutan researchers that made this project a success. I am relieved to see that construction of the early warning system has commenced.

Success No.1 World first prediction of mid-latitude climate variationsResearchers clarified the mechanism of the subtropical dipole modes that trigger abnormal weather in South Africa, and used the SINTEX-F high-resolution ocean-atmosphere coupled model to successfully predict mid-latitude climate variation.
Success No.2 Japan’s advanced science endorsed by local weather agencyThe official South Africa Weather Service (SAWS) rated the project highly and joined the research team partway through the project. This provided a route to continue towards practical deployment of the observation system after the project finished.
Success No.3 Win-Win connections between individuals were key to project’s successSeminars for local students and other active networking efforts to get to know people led to the merging of the South African observation results with the Japanese team’s simulation research. The human network created was instrumental in raising the level of results.
Next Steps Make climate variation predictions a part of ordinary life, like weather forecasts.The next step is to use the findings of our research to enhance the accuracy of climate variation predictions for mid-latitude areas of the northern hemisphere, including Japan. At the same time, we aim to make the predications useful for non-agricultural applications, including measures against infectious diseases carried by mosquitoes and other vectors, and water level adjustments for dams.
Success No.1 Using Japan’s space technology to create a Bhutan glacial lake inventoryUsing observation data from Japan’s Advanced Land Observing Satellite (ALOS), combined with a number of on-site GPS surveys, we made an accurate survey of Bhutan’s glacial lakes, creating and publishing an inventory containing the latest data on glacial lakes.
Success No.2 The first ever survey to scientifically identify glacial lakes posing a threat to the survey areaWe established a methodology for assessing risk using ASTER satellite data, based on characteristics such as the depression angle between the flat lake surface and the surrounding terrain. Scientific identification of glacial lakes posing a threat to the survey area in the Mangde Chu watershed was a world first.
Success No.3 Research findings reflected in measures to deal with GLOFsFrom the research findings, Bhutan recognized the importance of a system for monitoring watersheds for GLOFs, and has decided to move forward with construction of watershed early warning systems, and to establish a National Weather and Flood Forecasting and Warning Center.
Next Steps Use findings in research on the world’s glaciers under global warmingWith global warming, the method of using satellite data to assess the danger of glacial lakes can be extended to research on glaciers worldwide. Work is already proceeding on extending the method to the whole of the Himalayas and to the Andes.

The greatest success of this project was creating the network of people from different areas of expertise. We gathered together 200 researchers from the two countries despite systems not being fully in place during the first year of the SATREPS program, and we had to work hard to cover the
number of earthquakes and volcanic eruptions that actually occurred.
I am glad that we were able to help people suffering from fungal infection in Latin America. Having seen the sparkle in the eyes of the many graduate students who took part in the research in Brazil, I am convinced that our findings will be take hold and be passed on to the
next generation.

Success No.1 Over 200 researchers joined together in a massive networkOver 200 researchers joined together in a single network, divided into six teams to work on forecasting earthquakes, tsunamis, and volcanic eruptions, building a disaster-resilient society through both hardware (engineering) and software (social science) aspects, disaster education, and other areas.
Success No.2 Made progress in predicting volcanic eruptions and surveyed damage immediately after events during the study periodBy observing changes in ground surface gradient immediately before eruption, we were able to predict the type and scale of eruption. We also conducted surveys immediately after the 2009 West Java earthquake and the 2010 Mount Merapi eruption.
Success No.3 Used local and mass media to deliver disaster information to the people who need itConducted disaster education for schools and local communities, created evacuation simulations and teaching materials using pictures painted from direct experience of disasters, and conducted disaster education online using the Internet. Disaster education activities were included in local TV coverage.
Next Steps Continue with comprehensive disaster mitigation to save more livesFurther develop the research network formed by this project. Enhance disaster prevention technology through earthquake and volcano surveys, and work on practical, ongoing disaster education.
Success No.1 Communicated Japanese technology to local people and established a better diagnostic methodTransferred technology to Brasil relating to the DNA chips for identifying the strain of fungus, and to the new DNA detection methods: LAMP, and Realtime PCR. Established rapid and simple diagnosis and fungal strain identification methods.
Success No.2 The method allows identification of strains in districts where there is no budget for special equipmentThe ability to identify causative fungi with the naked eye using DNA chips or similar devices that require no special equipment is a game-changing technology developed in Japan. Moreover, the method is likely to be extensible to other types of infection.
Success No.3 The technology is being transferred worldwide, not just to BrazilWe have produced instruction manuals for the DNA chips and LAMP method, and made them available to other countries. We also produced a fungal infection diagnosis manual in Portuguese, and hope that it will be of use in Portuguese-speaking areas of Africa, too.
Next Steps Offering help to other regions with fungal infection issuesWe want to apply our research findings to countries in Africa and Latin America where there are many people living with HIV and there is a risk of fungal infections becoming widespread, and also to immunocompromised patients in Japan and other advanced nations with the aim of improving quality of life.
