• In spite of the long history of digital dentistry, the accuracy of the prosthetics fabricated with CAD/CAM systems is far from satisfactory. Jaw opening during taking impression elicits deformation of the mandible and the lower dental arch, and consequently causes the inaccuracy of occlusal relationship of the upper and lower dental arches on the CAD data. The method presented here utilizes the check-bite record at the maximum intercuspation to correct the relative positions among the teeth in the dental arches as well as between the arches. After this correction, the accuracy of the CAD data is satisfactory enough for the fabrication of the dental prosthetics which need no adjustment during their setting.

This method uses the newly-developed check-bite recording technique together with the conventional precious impression or optical impression techniques. It can easily be applied to the commercial CAD/CAM systems in the market. We hope to collaborate to the manufacturers of dental CAD/CAM systems to increase the accuracy of the systems.

• Dr. Katsunori Nonogaki has developed the novel ultrasound irradiation device, which can improve the autonomic nervous system activity and peripheral circulation. In addition, the ultrasoud device can improve hypertension and hyperglycemia within 20 min in subjects with drug-resistant hypertension and diabetes. Our initial device was approved in Japan (226AIBZX00028000). This device will be avaliable for the treatment of 1) muscle pain, 2) the autonomic neural dysfunction and stress-related disorders, 3) hypertention, and 4) diabetes. Moreover, the device will be usefull for your healthy life and aging care.

Our aims are to export the device internationally. We seek the investment and international business partners.

• Diabetes induces several complications, including retinopathy and nephropathy. In patients with type 1 diabetes as well as those with type 2 diabetes, pancreatic beta cells have reportedly decreased. Therefore, regeneration therapy of pancreatic beta cells may be very effective for major populations of diabetic patients. We discovered a neuronal network, from the liver, which selectively elicits pancreatic beta cell proliferation (Science 2008, Fig.). In a murine model with insulin-deficient diabetes, stimulation of this network improved diabetes. Thus, building devices which regulate the inter-organ neuronal network may lead to “regenerative therapy” for diabetes which regenerates pancreatic beta cells in the pancreas using patients’ own cells and patients’ own systems. We hope to conduct collaborative research with a willing company for a practical application of this technology.

• We succeeded in generating highly developed cultured C2C12 myotubes by manipulating intracellular Ca2+ transients with electric pulse stimulation (EPS), that are endowed with similar properties to in vivo skeletal muscle in terms of (1) excitation-induced contractile activity as a result of de novo sarcomere formation, (2) higher energy expenditure (as assessed by AMPK activation), and (3) improved insulin responsiveness (as assessed by exofacial myc-GLUT4 translocation assay).

Taking advantage of our “in vitro Exercise Model", our innovation will be an excellent alternative for the animal experimentation that can be applicable for a wide array of skeletal muscle research including drug screen.

• Losing cholesterol homeostasis with inborn errors of metabolisms or hepatobiliary diseases makes a change to in vivo cholesterol metabolism profile and causes the emergence of increased metabolites as conjugates in blood and urine. We have developed an LC/ESI-MS/MS method using fragment patterns characteristic of conjugation types for group-specific and comprehensive analysis of conjugated cholesterol metabolites. This method can contribute for an efficient discovery of diagnostic marker candidates toward various diseases.

After availability verification of candidates as diagnostic markers, it will be required screening tests. We have potential to collaborate with company for development of bioassay systems using antibodies or enzymes.

Beyond the classic function of bone, bone cells have been shown to regulate whole energy metabolism through bone-derived factors (osteokines). However, much of the research done to elucidate the pathophysiology of metabolic dysfuntion uses the classical approach of studying organs obviously implicated in energy metabolism. When Looking at the importance of skeletal integrity through the lens of evolution, we find that bone served a survival function. Humans had to consistently be mobile to look for food and shelter. Furthering this logic reveals that bone and energy metabolism are entwined. Therefore, this project aims to 1. identify bone factors that are associated with metabolic conditions and 2. to bridge our knowledge of the skeletal system represented by its cell types and our understanding of energy metabolism of the organism into one integrated subject.

Our research project offers a transformative advantage over conventional approaches by thinking with the end in mind (i.e translational potential) . We employ a multi-omics approach that goes beyond the conventional focus on single layers of biological information that will deepen our understanding of metbaolic diseases and accelerates identifying novel biomarkers and therapeutic targets.

• Interdisciplinary approach
• Multi-omics integration
• Translatioal potential

Our research offers potential for early diagnostics, novel biomarkers, and personalized therapeutic approaches for conditions like diabetes, osteoporosis, and diabetic osteoporosis. Our work fosters interdisciplinary collaboration and inspires future translational research and RnD with industrial partners.
This work promotes public awareness of the importance of bone health and ultimately aims to deliver tangible societal benefits.
