Researchers led by Osaka University used cryogenic electron microscopy to analyze the atomic structure of the centromeric region of the chromosome, essential for cell division. A protein called CENP-A marks the centromere; the researchers showed that during interphase, CENP-A is bound by a protein called KNL2 to maintain the location of the centromere. During mitosis, KNL2 is replaced by CENP-C, allowing correct formation of the kinetochore complex for cell division.

The results of this work could become foundational to drug discovery and development.
The fluorescent blinking of cyanine dye (Alexa Fluor 647, pink star) bound to RNA changes depending on the structure of the RNA. When the RNA is folded like a hairpin, the fluorescent blinking is fast, and when the RNA switches to a G-quadruplex, the blinking is slow (Akira Kitamura).

A process of continual learning for a synthetic multi-label dataset
31 Jan 2023
A research group at the Osaka Metropolitan University Graduate School of Informatics has developed a new learning method for artificial intelligence that combines classification performance for data with multiple labels with the ability to learn continually from data. Numerical experiments on real-world multi-label data indicate that the new method outperforms conventional approaches. The simplicity of this algorithm makes it easy to integrate it with other algorithms to devise new ones.

Researchers from Osaka University have shown that a system known as the GET pathway is essential for efficient mitophagy, the process by which mitochondria are removed from cells. The GET pathway targets a protein assembly called the Ppg1–Far complex, which inhibits mitophagy, to the membrane of a part of the cell called the endoplasmic reticulum. When the GET pathway is defective, this complex instead becomes targeted to mitochondria, where it acts to suppress mitophagy.

Researchers from Osaka University created a bound state of a proton and a K- meson known as Λ(1405), and measured its mass. The data implied that it consisted of five quarks. This work may help scientists develop a theory of exotic matter that existed in the early Universe or in neutron stars.
Schematic illustration of the spin transport demonstration of αNPD molecular thin film
24 Jan 2023
A research group, at the Osaka Metropolitan University Graduate School of Engineering, has succeeded in measuring spin transport in a thin film of αNPD molecules—a material well-known in organic light emitting diodes—at room temperature. They found that this thin molecular film has a spin diffusion length of approximately 62 nm, a length that could have practical applications in developing spintronics technology. In addition, while electricity has been used to control spin transport in the past, the thin molecular film used in this study is photoconductive, allowing spin transport control using visible light.

The research team identified a drug inhibitor that increased Robo4 expression and reduced mortality in sepsis and SARS-CoV-2 mouse models of infection. These findings may aid in the development of drugs to reduce the mortality rate of severe infectious diseases.
Sleeveless shirt-type wearable device and smartphone application track IBS patients’ sympathetic nervous system activity
12 Jan 2023
An Osaka Metropolitan University research group recorded the autonomic nervous system activity in patients with irritable bowel syndrome (IBS) and healthy subjects using a wearable device and a proprietary smartphone application to record daily life events such as defecation and sleep. As a result, they found that sympathetic nervous system activity was activated in IBS patients from 2 minutes before defecation and continued until 9 minutes after defecation. Further research is expected to improve the quality of life of IBS patients and elucidate the pathophysiology.

Measuring knee extension velocity without external load
11 Jan 2023
Osaka Metropolitan University scientists delved into the relationship between gait function and knee extension velocity after total knee arthroplasty and compared the effects of various factors on walking. The results reveal that knee extension velocity, measured while seated, on the operated side was the most important determinant of gait function. These findings are expected to contribute to the development of new rehabilitation programs for efficient gait function improvement.
Aspergillus aculeatus
10 Jan 2023
An Osaka Metropolitan University research team analyzed the regulatory mechanisms of carbohydrate-hydrolyzing enzyme production in Aspergillus aculeatus, a filamentous fungus that produces enzymes with an excellent ability to degrade plant biomass. The team found that UDP-glucose 4-epimerase (Uge5), an enzyme known for its involvement in galactose metabolism, also regulates the expression of degrading enzyme genes in A. aculeatus. This is the very first report of Uge5’s roles in selective gene expression in response to different types of inducing sugars in filamentous fungi.
X-ray fluorescence spectra analyzed using Bayesian estimation
06 Jan 2023

The ability to perform rapid non-contact elemental analysis in a nondestructive manner could lead to the widespread use of this technique in many fields, including the analysis of moving industrial products and waste materials while being carried on conveyor belts.
When the H5N1 HPAI virus (orange) affected a flock of crows in a public garden, it caused a mass die-off of crows. An Ezo red fox and a Japanese raccoon dog were also infected by the H5N1 HPAI virus, the former likely by consuming corpses of the crows, and the latter due to close contact with crow corpses (Illustration: Takahiro Hiono).
05 Jan 2023
Researchers at Hokkaido University have revealed the effects of high pathogenicity avian influenza virus infection on an Ezo red fox and a Japanese raccoon dog, linking their infection to a recorded die-off of crows.
