Monomer-Recycle System of Biodegradable Plastics by Industrial Fungal Fermentation and Application of Fungal Biosurfactant Proteins to Nanoparticles for Medical Use

Features
In 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)/Industry
The fungal biosurfactant protein is applicable to industrial recycling of biodegradable plastics and to production of immune-response free nano-particles for medical use.

IVR (Interventional Radiology) Treatment of Hypertention: Minimally Invasive Treatment of Primary Aldosteronism Based on the Adrenal Vein Sampling Technology

Features
Primary aldosteronism is a leading cause of secondary hypertension accounting for approximately 10 % of hypertensive patients; 4 million patients potentially exist in Japan. We aim to optimize the method of ablating aldosterone producing adenoma using newly developed bipolar radiofrequency ablation system with 300-400kHz high-frequency current and electric power of 40W (Celon Prosurge Applicator), and establish a less invasive interventional radiological treatment of primary aldosteronism.

Targeted Application(s)/Industry
Collaboration with medical equipment manufacture and universities are expected to develop new devices enabling ablation of aldosterone producing adenoma. Flexible guide-wire-type ablation system and rapid aldosterone assay system should be co-developed to tread aldosterone producing microadenoma which is difficult to detect due to its small diameter of less than 5mm.

Quantitative Evaluation of the Baroreflex Sensitivity of the Heart and Artery

Features
Metabolic syndrome is an important view point, when we consider the preventive medicine. Hypertension is one of the most important points to prevent the cardiovascular events. However, there is no method to measure the baroreflex sensitivity of the artery in the patients with hypertension. Tohoku University had invented the new method to evaluate the baroreflex sensitivity of the heart and artery (JP Patent No.4789203).

Targeted Application(s)/Industry
By the use of this machine, the baroreflex sensitivity of an artery in the patients can easily be measured noninvasively. It enables to predict the occurrence of hypertension and evaluate the therapy of hypertension easily, while allowing prevention of the cardiovascular events.

[Hydrogen Embrittlement]

Cavitation Peening

Features
Surface modification method to improve fatigue strength has been developed using cavitation impacts, which are normally causes severe damage in hydraulic machineries. The method was called "cavitation peening". In order to make clear the mechanism, a load controlled plate bending fatigue test machine was developed. It was proved by using the test machine that the threshold level of stress intensity factor was improved about 1.9 times by cavitation peening. The mitigation of hydrogen embrittlement by cavitation peening was also improved.

Targeted Application(s)/Industry
The cavitation peening can apply to component of automobile and forging die. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry.

Synthesis of Novel Nano-Carbon Materials Using Nano-Space as a Reaction Field

Features
We are designing and developing novel nanocarbon materials together with their hybrids by controlling the reaction nano-fields for the syntheses of these materials. One example is fully tailored carbon nanotubes with uniform diameter and length. Another noteworthy material is zeolite-templated carbon which has structure regularity like zeolite and a surprisingly large surface area up to 4000 m2/g. In addition, we have recently developed a method for a complete coating of the entire surface of mesoporous silica with graphene layers.

Development of Grass-field Shorthorn Cattle and it's Innocative Green-Technology for Sustainable and Improving Beef Production

Grass-field Shorthorn Cattle（trademark registration No. 5270386 Fig.1）that possess a loss of functional myostatin result in the double-muscled phenotype with generalized hyperplasia and hypertrophy of the muscle. The cattle were developed form Japanese Shorthorn Cattle, and have superior carcass characteristics including a larger proportion of muscle (about 50% more muscle mass than normal-muscled cattle), lower proportions of fat and more tender meat (Fig. 2). The increased lean beef production shows that Grass-field Shorthorn Cattle are estimated to be a hopeful breed as meat cattle in days to come. Therefore, we are studying the further development of Grass-field Shorthorn Cattle and it’s whole mechanisms of increased muscle muss (Fig.3) as a new breed to reduce the environmental loading on beef production. The goal of our research is to establish innovative Green-Technology for sustainable and improving beef production of GSC and to utilize them for practical use.

[Hypoxia-Inducible Factor alpha, HIF-a]

Development of PHD-Targeted Drug for Ischemic Injury

Features
All the living organisms generate energy from molecular oxygen to maintain their own lives. Once the concentration of oxygen falls down, life activity gets severely hampered and it could sometimes cause death. Typical examples that are related to local hypoxia are ischemic heart disease, stroke and kidney disease.
We focus on the function of prolyl hydroxylase (PHD) as a sensor to detect the hypoxia, and we are developing drugs to treat ischemic injury by controlling hypoxia.

Targeted Application(s)/Industry
Currently, we have several compounds that inhibit the PHD. We want to commercialize in conjunction with pharmaceutical companies in Japan and overseas, advancing our non-clinical studies for clinical development.
