A joint research group at Osaka Metropolitan University has succeeded in regulating the flow of single molecules in solution by opening and closing the nanovalve mounted on the nanofluidic device by applying external pressure. The research group fabricated a device with a ribbon-like, thin, soft glass sheet on the top, and at the bottom a hard glass substrate having nanochannels and nanovalve seats. By applying external pressure to the soft glass sheet to open and close the valve, they succeeded in directly manipulating and controlling the flow of individual molecules in solution. They also observed an effect of fluorescence signal amplification when single fluorescent molecules are confined in the tiny nanospace inside the valve. The effect can be ascribed to the nanoconfinement, which suppresses the random motion of the molecules.

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.

Osaka Metropolitan University scientists discovered the principle of light-induced acceleration of antigen–antibody reaction, allowing for simple, ultrafast, and highly sensitive detection of proteins. The researchers introduced target proteins and probe particles with modified antibodies selectively binding to the target proteins into a small channel and applied irradiation with infrared laser light. They achieved, for the first time, the rapid measurement of trace amounts of attogram-level target proteins after only 3 minutes of laser irradiation. These findings will potentially contribute to breakthroughs in the development of systems for ultra-early diagnosis of various diseases.

Osaka Metropolitan University researchers introduced seven proteins, thought to let bacteria swim by switching the direction that their helical bodies spiral, into a strain of synthetic bacterium with minimal genetic information. As a result, they confirmed that the synthetic bacterium named syn3, which is normally spherical, formed a helix that could swim by spiraling. Further investigation revealed that only two of these newly added proteins were required to make syn3 capable of minimal swimming. This swimming synthetic bacterium can be said to be the smallest mobile lifeform genetically, as it contains the fewest number of genes.

A research group at the Osaka Metropolitan University Graduate School of Science has revealed a new system that allows them to control the behavior of the nematode worm Caenorhabditis elegans, using two different animal opsins, a type of light-sensitive protein. The first opsin was expressed in the worms’ sensory cells responsible for triggering avoidance behavior, making the worms move. This opsin was found to be approximately 7,000 times more sensitive to white light than the commonly used optogenetic protein channelrhodopsin-2. Likewise, a UV-sensitive opsin was expressed in the worms’ motor neurons, causing the worms to stop when exposed to UV light and start moving again when exposed to green light. Both opsins tested can be switched on and off repeatedly without breaking down, making them robust tools for future research, including the field of drug discovery.

This is a novel study that attempted to construct a pH-sensitive delivery system into T cells and their subsets using carboxy-terminal Phe- and CHex-modified dendrimers with different structures, i.e. PAMAM-CHex-Phe and PAMAM-Phe-CHex. The findings contribute to the development of nanoplatforms for direct delivery to T cells to control the functions of T cells, which play key roles in cancer immunotherapy. This is the first report on direct delivery into T cells using pH-sensitive DDS.

Garden soil houses a variety of bacteria and their natural byproducts — including one that may help halt tumor growth. Lankacidins are molecules that can be isolated from Strepomyces rochei, a common bacterium in soil. In addition to antimicrobial properties, a type of lankacidins, called lankacidin C, can inhibit tumor activity in various cancer cell lines, including leukemia, melanoma, ovarian and breast cancers. Lankacidin C offers a potential foundation on which to design anticancer drugs, but its structure is complicated and difficult to manipulate, according to an international research group. The same group recently identified where antitumor activity is housed on the molecule and has now used that information to simplify lankacidin as a potential starting point to engineer treatments.

When it comes to cancer, clarity is key. The ability to visualize cancerous tumors and metastatic tissue three dimensionally (3D) can help clinicians diagnose the precise type and stage of cancer, while also informing the best treatment methods. To obtain an even clearer tissue for imaging, a research team based in Japan has tested the effectiveness of specialized hydrogels. Acting as a 3D molecular network, these hydrogels can rapidly remove fats from tissues, which are a factor in tissue opacification, without losing their structure. The material is used in several biomedical devices, including contact lenses.

Cells translate their genetic material at rapid rates with exquisite precision to reproduce, repair damage or even combat disease. But the process can deregulate and give rise to disease. Byproducts of errant processes can build up like gunk in the gears, especially around neurons, breaking down the repair mechanisms and causing further damage and even neurodegenerative disorders such as Alzheimer’s disease.

Publication bias, or the tendency of researchers and journals to not publish uninteresting findings, plagues much of the natural sciences and especially biomedical research. Hiroshima University researchers have developed a meta-analytic technique exploiting publicly available transcriptome databases that avoids the problem—and in so doing, discovered four genes previously unknown to be associated with responding to low-oxygen stress.

Giants in history
Filipina chemist María Orosa (29 November 1892–13 February 1945) fought malnutrition and food insecurity in the Philippines by devising over 700 culinary creations including Soyalac, a nutrient rich drink made from soybeans, and Darak, rice cookies packed with Vitamin B1, which could prevent beriberi disease caused by Vitamin B1 deficiency. She was also a partisan of the guerrilla movement resisting Japanese occupation during World War II, and died after being struck by shrapnel while working in her laboratory during the Battle of Manila.
Chinese agronomist Yuan Longping (7 September 1930 – 22 May 2021) developed the first varieties of the high-yield, hybrid rice that brought food security to multiple countries including China, which had been ravaged by food shortages as recently as the mid-20th century.
A Japanese surgeon, Tetsuzo Akutsu (20 August 1922 – 9 August 2007) built the first artificial heart capable of keeping an animal alive.
