A technology for measuring the stiffness and viscosity of biological tissues using shear waves and ultrasound.
- Ultrasound imaging
- Viscoelasticity measurement
The true "hardness" of biological tissue is determined by a combination of elasticity (hardness) and viscosity (toughness). This research proposes a technique for non-invasively and accurately measuring the elasticity and viscosity of biological tissue. The proposed method generates shear waves of various frequencies within the body and calculates their propagation velocities from ultrasound images. By representing the frequency characteristics of the shear wave propagation velocity with a physical model composed of elastic and viscous elements, elasticity and viscosity can be simultaneously estimated from the model parameters.

Thursday, May 14th, 10:00 AM - 1:00 PMEvaluation of human cell maturation and function based on differences in bioreactor stirring methods.
- bioreactor
- cell manufacturing
- cell therapy
While large-scale cell culture is essential for the practical application of cell therapy, "cost" and "maturation" remain challenges. Suspension culture is suitable for efficient mass production, but the shear stress (mechanobiological stimulation) caused by agitation affects cell proliferation and properties. In this study, we aimed to achieve cell control through this physical stimulation and cultured human cells using bioreactors with different agitation methods. By comparing their behavior and function, we evaluated the impact of the agitation method on cells.

- Alternatives to animal testing
- In vitro models
- tissue engineering
This research aims to create a skin model using 3D bioprinting that precisely reproduces the three-layer structure of the epidermis, dermis, and subcutaneous tissue, as well as the vascular network, and enables long-term culture for several months through connection to a perfusion system. It can reproduce natural cell turnover and chronic toxicity, making it applicable to safety evaluation of cosmetics, cleansers, and pharmaceuticals. Because layer thickness and cell composition can be freely controlled, individualized models can be created, and standardized processes enable low-cost, highly reproducible mass production.

- Wearable
We are conducting research on energy harvesting technology that converts minute movements present in the everyday Enviromental protection into electrical energy using "friction." In this research, we are developing a wearable power-generating suit that harvests electricity from human body movements. This power-generating suit converts movement into electrical energy by utilizing friction caused by the rubbing of clothing against itself. Although the amount of power obtained is small, it is expected to have future applications in Healthcare services field, such as auxiliary power sources for wearable devices and motion sensing.

Thursday, May 14th, 10:00 AM - 1:00 PMNovel fluorine-free surface treatment agent enhanced with natural ingredients.
- Fluoride-free
- Difficult to adhere to surfaces
- Use of natural products
Fluorine compounds have been widely used as surface treatment agents due to their excellent water-repellent and oil-repellent properties. However, in recent years, as the risks of fluorine compounds to human health and Enviromental protection have become clear, there is a strong demand for the development of alternative technologies. To address this social problem, with the support of NEDO, we are working on developing fluorine-free surface treatment agents using a new approach of functional enhancement with natural products. This research introduces the development concept, an overview of the surface treatment agent prototype, and their performance.

The diagnosis of illness based on odors such as body odor and bad breath is known as olfactory diagnosis. Body gases, which are the source of odors, contain more than 1,000 chemical components and are known to reflect physical condition and diseases. Establishing a highly sensitive body gas measurement method is expected to enable the provision of non-invasive Healthcare services devices. In this research, we are working to identify gas biomarkers that correlate with physical condition and diseases through biogas analysis, and to develop a small gas sensor that enables the measurement of body gases.

- Liquid film evaporation
Improving motor performance is a crucial challenge in the electrification of mobile devices such as electric vehicles, electric aircraft, and liquid rocket engines using electric motor pumps. In improving the performance of high-power motors, cooling the heat-generating magnets is a key issue. Therefore, we are developing a liquid film evaporative cooling system for motors, optimizing the flow system to achieve uniform thinness of the liquid film, and exploring surface structures for the heated surface to achieve high heat flux.

To build a green society, the existence of devices that can efficiently and abundantly store renewable energy is essential. In this research, we designed novel high-sulfur-content materials by chemically modifying sulfur, with the aim of developing next-generation secondary batteries that are inexpensive and enable high energy density. Since these materials exhibit different physical properties (adhesion, ductility, solubility) from conventional sulfur, we aim to develop high-performance lithium-sulfur secondary batteries using them as cathode active materials.

AI/DX Nutrition is a research project based on Exposome biology (a new field of study that scientifically examines the overall impact of external factors such as diet, Enviromental protection, and lifestyle on the body). It measures the body's condition, including blood amino acids, in a low-burden way, predicts health status and future risks using AI, and designs these using digital transformation (DX). This project aims to develop core technologies that design optimal diets and lifestyles for individuals based on this information, thereby improving health while simultaneously reducing food and resource waste.

Thursday, May 14th, 10:00 AM - 1:00 PMAnalysis of genomic segment complementation using genomic segment-deficient influenza viruses
- Virology
- Influenza A virus
- Digital assay
In influenza A virus, the genomic RNA is segmented into eight strands, resulting in a large number of non-infectious particles with missing parts. However, multiple non-infectious particles may compensate for genomic deficiencies within a single cell, potentially restoring infectious function, suggesting a role for these non-infectious particles. In this study, we created segmentation-deficient artificial viruses and attempted to demonstrate genome complementation infection and analyze the properties of the deficient viruses by co-infecting cells with these deficient viruses under particle number control using a digital assay.

Thursday, May 14th, 10:00 AM - 1:00 PMMathematical research on error catastrophe avoidance in influenza viruses
- Influenza virus
- Genome complementation
- Mathematical models
Influenza viruses have a high mutation rate. While this is advantageous for Enviromental protection adaptation, the accumulation of mutations can lead to extinction. In fact, it has been reported that approximately half of them have genome defects, and more than 99% cannot infect on their own. In this study, we constructed a mathematical model that assumes genome complementation between particles as a mechanism for successful infection under these circumstances. The results suggest that even under high mutation rates that would lead to extinction through single-virus infection, genome complementation prevents the population from becoming extinct. This deepens our understanding of the survival strategy of this virus and could influence infectious disease control measures.
