Research & Education

Research content

1. Nutritional epidemiology of essential trace elements
Essential trace elements such as zinc, copper, and selenium have been demonstrated to play important roles in the regulation and homeostasis of various biological functions including the central nerve system, immunological system, and anti-oxidative protection. The essential trace elements relate to several phenomena such as aging, neural disorders, diabetes and other diseases.
We examine the health influence of the essential trace elements deficiency and try to investigate the effect of additional supplementation of these elements.
2. Analytical chemistry of selenoproteins
We have developed an analytical method that determines several selenoproteins simultaneously using ICP-MS combined with a chromatographic separation. For example, selenium (Se) often works as a catalytic center of seleno-enzymes. In Se-deficient mouse, the activity of glutathione peroxidase, a seleno-enzyme acting as a radical scavenger, lowered in parallel with the disappearance of Se from this enzyme fraction. We have been trying to clarify the relationships between the metabolism of essential elements and human health.
3. Interaction between selenium and cadmium
4. Cohort study
We conduct a large-scale epidemiological research to clarify risk factors of cancer, stroke, cardiovascular diseases, and aging-related disability.
5. Epidemiological study of childhood allergy over Gunma prefecture.
6. Komo-Ise Study (A cohort study of middle aged and elderly residents. An analysis of the risk of psychosocial factors on mortality and morbidity.)
7. Mathematical models of infectious diseases focusing human behavior
8. Anthropological population demography
9. Health and Medical Information Management System
10. Screening and causal inference of depression for suicide prevention (Collaborative study with Gunma prefecture).
11. Development of selenium fortified sprouts.
12. Direct determina
tion of ceruloplasmin/plasma copper using HPLC-ICP-MS for diagnosis of Wilson disease.

Business education

1. Public Health:
a scientific lecture on the general public health.
2. Exercise of Data Processing for Medicine:
leaning of medical statistics and practice of the analysis using statistics software.
3. Practical Training Course of Community Health Care:
individual practice (setting the assignment -> practice -> presentation)
4. Community Health Care and Medicine:
confirmation of the fundamental and current knowledge.
