More than half of patients suffer long COVID symptoms
24 Feb 2023
A research group from the Osaka Metropolitan University Graduate School of Medicine conducted a survey of 285 patients regarding the long-term aftereffects of COVID-19. As a result, they revealed that more than half of COVID-19 patients still had residual symptoms, even close to a year afterward. It became clear that fatigue, abnormalities in senses of taste and smell, hair loss, and sleep disorders could persist, regardless of the severity of the initial COVID-19.

Antioxidants discovered in meat!
16 Feb 2023

Furthermore, they established a method to selectively and sensitively detect very small amounts of 2-oxo-IDPs and revealed for the first time that several types of 2-oxo-IDPs are contained in meat, including beef, pork, and chicken.

To clarify the mechanism of serial dependence in number perception, a research team from Osaka Metropolitan University conducted two tests, independently asking subjects to estimate the number of coins, or to estimate the value of those coins, shown on-screen for half a second. The results showed that serial dependence was confirmed in both tasks and that the most significant effect on serial dependence was not caused by the last stimuli, but the subjects last response. These results indicate that higher-order cognitive processing has a greater influence on the occurrence of serial dependence.

Researchers from Osaka University have shown sex-specific differences in the immune response to COVID-19 infection. By identifying and analyzing the immune cell population in COVID-19 patients, they showed that infection results in a reduced ratio of circulating follicular T regulatory (cTfr) cells to a network of antibody-producing proteins, correlated with dysregulated antibody production. This cTfr cell reduction is more significant in males, providing cellular evidence for the observed association between increased risk and male sex.
Thermal conductivity of 3C-SiC compared to other semiconductor materials
13 Feb 2023
A research group from the Graduate School of Engineering at Osaka Metropolitan University has shown that 3C-SiC exhibits high thermal conductivity equivalent to the theoretical value, based on thermal conductivity evaluation and atomic-level analysis, for the first time. They demonstrated that a 3C-SiC film on silicon substrate had a high thermal conductivity and expect that fabricating large-diameter wafers can be achieved at a low cost. The discovery should lead to improved heat dissipation in everyday electronic devices.

In hepatic steatosis, hepatocytes "die," resulting in liver damage. Severe steatosis increases hepatocellular deaths, thus aggravating liver damage. The mechanism is unclear. Using mice, we show that mild steatosis causes apoptosis whereas severe steatosis predominantly causes necroptosis leading to cell rupture. This induces strong inflammation and new cell death, producing further liver damage. We reveal the transcription factor ATF3 to be involved in this process. Our results are expected to contribute to therapeutic method development.

The group then verified the validity of the mathematically derived evaluation method by measuring the diameter of X-ray microbeams using metal wires of various diameters with an X-ray fluorescence analysis system for small areas and found that it was possible to calculate the beam diameter more accurately than the previous conventional evaluation method.

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.
