Functional imaging using methods for molecular imaging; Kinetic modeling using PET; Activation studies with O-15 water or fMRI
ƒRƒƒ“ƒg

The research target of the Division of Biomedical Imaging is to generate, analyze and translate various functional in vivo images using positron emission tomography (PET), MRI and other modalities of medical imaging devices. Kinetic modeling with physiological analysis and applying molecular imaging methods to clinical studies are good examples of our research target. Brain activation studies using fMRI are also a major subject of our research interest.

Development and evaluation of new molecular imaging probes for PET
ƒRƒƒ“ƒg
My interest is in visualizing the changes in our body non-invasively using molecular imaging probes. I have been developing new molecular imaging probes to image cardiac sympathetic nervous function and noradrenergic nervous function in the brain. Now I am starting to develop new tumor imaging probes and probes for internal radiation therapy.

I have studied on evolution of protosynthesis in eukaryotes in University of Tsukuba until 2004 June and then moved to BIRC, University of Fukui. I am interested in evolution of eukaryotes and their symbiotic evolution. My recent research subject is metabolic analysis of ptotist and animal cells and the evolutionary implication.

Development of cognitive function in children using Magnetic Resonance Imaging (MRI).
ƒRƒƒ“ƒg
The objective of my research is to clarify the processes and mechanisms of development of cognitive function in children from aspects of neuronal activity and brain anatomy. I will use MRI to reveal: 1) Development of brain neural network, 2) Development of brain morphology, 3) Development of cognitive function in children, adolescents, as well as adults. At the same time, I will examine which types of lifestyle and living environment will affect children's brain development by conducting neurocognitive function tests and questionnaire surveys.

Neuroimaging study of neural substrates related with mental disorders.
ƒRƒƒ“ƒg
Methods of investigation for diagnosis of mental disorders are wanted. To develop such methods, biological understanding of mental disorders is very important. For that purpose, we conduct studies about neural activities and their network of a human brain with a magnetic resonance imaging (MRI).

1. Molecular mechanisms of Interdisciplinary cancer therapy based on radiotherapy 2. Molecular mechanisms of radiation-induced bystander effect and adaptive response 3. Biological effects by heavy ion radiation
ƒRƒƒ“ƒg
Cancer control is a problem of pressing urgency because cancer is the leading cause of death for the last several years in Japan. To overcome the problem, some new strategies for cancer control, such as immunotherapy, hyperthermic therapy and gene therapy has been developed for cancer patients in addition to standard therapies by operation, anti-cancer drugs and radiation. The elucidation of molecular mechanisms of anti-tumor effects by the interdisciplinary combined treatment with such therapies allows us to establish the tailored cancer therapy for individual cancer patients. Also the elucidation of molecular mechanisms of radiation-induced adaptive response and bystander effect is important from the aspect of radioprotection against X-rays, gamma-rays, and heavy particles.

In the immature rat brains, the ratio of aerobic glucose metabolism to the total glucose metabolism was low compared with the adult rat brains, suggesting only slight involvement of free radicals in hypoxic neurotoxicity. These data suggest that the higher resistance of immature brains to hypoxia compared to that of adult brains is attributable to a lower involvement of free radicals due to a lower aerobic glucose metabolic rate.

Development of F-18 radiopharmaceutical for PET imaging of infections.
ƒRƒƒ“ƒg
Development of more efficient and less time-consuming reactions to synthesize new PET radiotracers is a challenge for radiochemists due to the short half-lives of positron-emitting radioisotopes. Aminosugars labeled with positron-emitting radioisotopes have been investigated for the in-vivo evaluation of biochemical processes in cancerous tissue. Since aminosugars are obligatory structural components of many biologically important macromolecules including glycoproteins and polysaccharides, they could also be used for imaging infection using PET. The aim of my research is to develop aminosugar labeled compounds which will contribute to progress in PET imaging of infections.

The rapid advance in molecular and cellar biology has brought us ever growing knowledge of molecular events underlying physiological and pathological changes in our body and enabled new types of therapy directly targeting the molecular events. My interest is in visualizing the changes in our body non-invasively using radiolabeled probes at the molecular level, typically as the changes in gene expression, to realize the quicker and more accurate diagnosis and to choose effective therapy protocols, as well as to further deepen our understanding of the mechanisms supporting our life.

Recent progress in molecular biology brings us a new insight of diseases, namely abnormality of gene expression. Our focus is to develop molecular probes which allow us to visualize disease-related gene expression non-invasively. Present target organs are brain, heart and tumors. Internal radiation therapy agent labeled with beta emitting nuclide is also under development.
