特徴・独自性
  • The concept of LCS (low carbon society) is a unique approach having multi-dimensional considerations such as social, economic and environmental dimensions. The LCS aims at an extensive restructuring of worldwide energy supply/demand network system by not only replacing the conventional parts with the new ones, but also integrating all the necessary components and designing absolutely different energy networks. An energy-economic model is a tool for decision making for a variety of purposes, such as energy security planning, climate policy analysis, and technology innovation assessment.

Development of devices regulating inter-organ neural network for diabetes therapy

NEXT
PREV
特徴・独自性
  • 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.

Development of New Drugs and Devices Regulating Inter-Organ Neural Network for Obesity Therapy

NEXT
PREV
特徴・独自性
  • Obesity induced the metabolic syndrome, which causes cardiovascular diseases. Obesity has now become a major health concern not only in developed countries but developing countries. However, diet and exercise are still major therapies. We discovered endogenous systems maintaining homeostasis of energy metabolism and revealed several neuronal networks among organs to be responsible for the regulation systems.
  • 1) Afferent neuronal signals from adipose tissue regulate appetite and prevent over-eating during obesity development (Cell Metab 2006)
  • 2) Neuronal network from the liver enhances basal metabolic rates to prevent obesity development when energy store is increasing (Science 2006) 3) Neuronal network from the liver suppresses adaptive thermogenesis in brown adipose tissue (Cell Metab 2012).
実用化イメージ

On the basis of these original discoveries, we are aiming at developing new drugs and/or building devices which regulate the inter-organ neuronal networks and hope to conduct collaborative research with a willing company for a practical application to obesity therapy.

Precipitation Hardened Co-based Alloy

NEXT
PREV
特徴・独自性
  • The high-temperature strength in Co-based alloys is inferior to that in Ni-based superalloys due to no available ’ phase for strengthening Co-based alloys. We have found a new intermetallic compound Co3(Al,W) ’ phase, and /’ Co-Al-W-based wrought and cast alloys show excellent high-temperature strength. The /’ Ir-Al-W-based alloys are also available for high-temperature uses at over 1100 °C. The Co-based alloys also have good wear resistance. For example, friction stir welding (FSW) of high-softening-temperature materials such as steels and titanium alloys is possible using a Co-based alloy tool. We hope to conduct collaborative research with willing company for a practical application of the Co- or Ir-based alloys for high-temperature uses including FSW applications.

Selective recovery of tocotrienol from vegetable oils using ion-exchange resins

NEXT
PREV
特徴・独自性
  • Tocotrienol, one of vitamin E, has recovered by the conventional method with molecular distillation from deodrizer distillate discharged from the oil refining processes. However, tocotrienol easily loses its activity due to its low thermal stability, so that its recovery ratio and purity were extremely low. We proposed a novel method to selectively recover tocotrienol by adsorption/desorption using anion-exchange resin at 50 degree C. Tocotrienol is retained on the resin by ion-exchange reaction, and then released and recoverd from the resin by other ion-exchange reaction. Prior to the adsorption/desorption, free fatty acid, a major component of the feed, should be removed by esterification using cation-exchange resin at 50 degree C.
実用化イメージ

This innovative technology succeeds in solving the serious problems in the current tocotrienol production, the large weight loss due to the thermal decomposition and large amount of remaining impurities. This technology applies to the production of not only tocotrienol but also tocopherol as bioactive compounds s in food chemicals.
