Methods to Restore Strelity of Gramineous Plants under High- and Low-Temperature Stress ConditionsFeaturesPlant reproductive development is more sensitive than vegetative growth to many environmental stresses. High-temperature injury is becoming an increasingly serious problem due to recent global warming. In wheat, barley, and other crops, the early phase of anther development is most susceptible to high temperature. Oppositely, grain yields in rice plants are often reduced by exposure to low temperature. Unexpected climate change, such as abnormally hot or cool summer temperatures, have occurred repeatedly during recent years. This method indicates that an appropriate use of specific phytohormones, such as auxin and GA, may promote stress tolerance and adaptation to abiotic stresses. Targeted Application(s)/IndustryThese potentially novel functions of the classical phytohormones will be important sustainable agriculture in the face of global climate change. |

We perform various materials processing using non-equilibrium reaction field induced by microwave and/or ultrasonic irradiation. The topic contains powder metallurgy, nitride coatings, synthesis of new functional materials, fabrication of nanoparticles, etc. Recently we have developed a new TiN coating method using our microwave irradiation equipment operated at a frequency of 2.45 GHz. The method is simple but applicable to various substrates with complex shape. This method can be applied to various nitride coatings and will open a new coating technology in many fields of applications. Targeted Application(s)/IndustryThe major targets of TiN coatings are for cutting tools, ball bearings, dental implants, die and mold for stamping, and ornaments. The newly developed method makes it possible to perform nitride coatings within a short time using a standard microwave heating equipment.

Molecular Imaging from Basic Research to Clinical ApplicationFeaturesMolecular Imaging and its Application to Drug Development: Positron emission tomography (PET) comprises the administration of carbon-11- or fluorine-18-labeled tracers to human subjects in order to describe the concentration-time profile in body tissues targeted for treatment. As PET involves the administration of only microgram amounts of unlabeled drug, the potential risk to human subjects is very limited. Consequently, required preclinical safety testing is reduced as compared to conventional human studies. Targeted Application(s)/IndustryPET molecular imaging studies are gaining increasing importance in clinical drug research, as they have the potential to shorten time-lines and cut costs along the critical path of drug development. We have developed several PET tracers for molecular imaging such as amyloid imaging and central nervous system drug research at Tohoku University, Japan. We will present the recent progress and strategy of "PET molecular imaging" in order to accelerate drug development.

Monomer-Recycle System of Biodegradable Plastics by Industrial Fungal Fermentation and Application of Fungal Biosurfactant Proteins to Nanoparticles for Medical UseFeaturesIn Japan, solid-phase fungal fermentation systems using the industrial fungus Aspergillus oryzae have been extensively used for producing fermented foods such as soy sauce and sake; the annual production volume of the products is over one million tons. The efficient enzymatic hydrolyzing systems are expected to be applicable to biological recycling of biodegradable plastics. We found that A. oryzae can effectively degrade polybutylene succinate-coadipate (PBSA) by the combination with an esterase (cutinase) CutL1 and novel surfactant proteins, RolA and HsbA that are attached to the surface of PBSA and then recruit CutL1. The recruitment of Cutl1 by the surfactants stimulated PBSA degradation. Targeted Application(s)/IndustryThe fungal biosurfactant protein is applicable to industrial recycling of biodegradable plastics and to production of immune-response free nano-particles for medical use. |
