Osaka Metropolitan University scientists conducted a 7-year study on seedling recruitment and mortality in a national park in Chiang Mai, in northern Thailand. During the study period, an extremely strong El Niño event occurred, leading to a stronger and longer drought than normal. Seasonally dry tropical forests (SDTFs), which experience an annual dry season, are considered drought-tolerant. Nevertheless, the study found that seedling mortality increased in SDTFs when severe and prolonged drought occurred. The mortality rate was greater in evergreen forests at higher elevations that usually experience less severe drought than in deciduous forests at lower elevations where severe drought is more common. The study results advance the understanding of the effects of El Niño on seedling dynamics in SDTFs.

Researchers from Osaka University have demonstrated a proof-of-concept for a novel molecular hydrogen production method that bypasses the need for expensive purification steps. They developed a system where hydrogen is separated and stored in liquid organic hydrogen carriers by catalysis of triaryl boranes in one seamless process. The results of this work will help facilitate the transition to a hydrogen-based economy that is necessary for a more sustainable future.

Researchers from The Institute of Scientific and Industrial Research (SANKEN) at Osaka University and collaborating partners prepared hierarchical hydrogels and moldings that consisted of anisotropic, ecofriendly cellulose nanofibers. By simply tailoring the applied voltage during fabrication, complex architectures—such as microneedles and multilayer hydrogels—were easy to prepare. The results of this work will reduce the need for petroleum-based plastics, and in so doing minimize a long-standing source of environmentally persistent waste.

An Osaka Metropolitan University researcher has provided a review article regarding INSL3, a circulating hormone secreted from the gonads, in domestic animals, in comparison to rodents and humans. In this review article, the author describes his research group’s work that (1) developed immunoassays, for the first time, that can measure circulating INSL3 in multiple domestic mammals, including cattle, goats, sheep, pigs, horses, and dogs, (2) provided evidence in studies with bulls and bucks that INSL3 offers more reliable and stable values by a single blood collection than testosterone, a conventional and well-known testicular hormone, and (3) suggested that blood INSL3 concentrations would be a good biomarker for testicular and reproductive functions in normal and abnormal male domestic animals. These findings suggest that the INSL3 assay might simplify the evaluation of reproductive functions in various male domestic animals. In particular, the assay method may facilitate earlier selection of valuable male animals such as beef sire bulls (Image) with higher reproductive performance, contributing to reductions in the labor and costs required for sire production.
Dietary considerations for nutritionists supporting para-athletes
20 Oct 2022
Osaka Metropolitan University researchers interviewed active para-athletes with lower-limb disabilities who compete at an international level, about diet and nutrition. The research team found that what para-athletes considered an ideal diet was not necessarily optimized for improving athletic performance, and even when para-athletes understood diets geared towards athletic performance, characteristics of their disabilities impose barriers to implementing dietary changes. Understanding these concerns and struggles is important for nutritionists who support para-athletes in sports nutrition.

Scientists have uncovered new details of how ice forming below the ocean surface in Antarctica provides cold dense water that sinks to the seabed in an important aspect of global water circulation.
Human mobility and COVID-19 in suburban cities
19 Oct 2022
Osaka Metropolitan University researchers conducted a study of human mobility to find effective lifestyle changes that enable people to exist with the novel coronavirus COVID-19, while maintaining social and economic activities. They found that restricting the human mobility in specific areas according to the state of the pandemic, rather than uniformly controlling human mobility, could be effective in reducing the number of new COVID-19 infections.

Pyroxenes are a major group of rock-forming minerals. Osaka Metropolitan University scientists investigated the iron ion status of a calcium-rich pyroxene, using Mössbauer spectroscopy on thin sections of single crystals. The study revealed that in pyroxene crystals consisting of roughly 50% calcium, the tensor that determines the ratios of iron ions at the Mössbauer spectral peaks in the M1 sites—one of two types of cation positions in the pyroxene crystal structure—is independent of the iron content but dependent on the calcium content. The research findings have clarified one of the physical properties of pyroxenes, facilitating detailed future analysis of iron using Mössbauer spectroscopy on mineral flakes.

Osaka Metropolitan University researchers have created intermetallic alloy nanoparticles of palladium and zinc with an alternating arrangement of zinc and palladium atoms. The intermetallic alloy is more corrosion-resistant than substitutional alloys while retaining the electrocatalytic properties of both metals, which could be useful for developing new non-precious metal electrocatalysts.

Researchers from Osaka University have developed a way of printing edible QR codes—a kind of barcode—within cookies, meaning that the tag is embedded within the food itself. Crucially, the tag doesn’t change the flavor or outer appearance of the cookie, and can be read using a backlight while the cookie remains intact. This new method has great commercial potential for improving food safety and traceability in an environmentally friendly way.

Researchers from Osaka University have developed a skin-like device to measure brain activity via electroencephalography, which uses electrodes to measure electrical activity on the scalp (reflecting underlying brain activity). The device has other useful applications, such as measuring heart rate and blood oxygen levels. Wearable devices that can remotely assess brain health in everyday settings are likely to improve healthcare for millions of people worldwide.

Researchers from Osaka University have shown that deficiency of the protein Favine can lead to accelerated development of atherosclerosis. Loss of Favine in a mouse atherosclerosis model also led to calcification and thrombus development in the blood vessels of the mice. Prior to this, no mouse models for calcification or thrombus formation existed, hindering atherosclerosis research. This work also identifies Favine and its downstream signaling pathway, known as MEF2C-KLF2, as potential therapeutic targets for atherosclerosis.

Researchers from Osaka University have found that the Vibrio cholerae colonization factor TcpF forms a flower-shaped trimer to specifically bind to the minor pilus protein TcpB resulting in secretion by the type 4 pilus secretion system into the extracellular space. This finding could help lead to the development of a novel anti-adhesive drug that selectively interrupts the TcpF-TcpB interaction, which may replace antibiotics in the treatment of cholera.

Researchers from Osaka University have developed a computational analysis tool called CAPITAL for comparative analysis of single-cell RNA sequencing data with complicated branching trajectories. As cells undergo a dynamic process, they can be placed on a “pseudotime trajectory” to analyze the gene expression changes throughout the process. While previously only straightforward linear trajectories could be compared, CAPITAL is proven to be able to accurately compare branching trajectories, significantly advancing the field of high-throughput single-cell sequencing.
