Broad transfer range of IncP1-type plasmid and its applications
17 Jun 2021
Researchers from Hiroshima University now have a better understanding of the mechanism underlying how certain bacteria can transfer genetic material across taxonomic kingdoms, including to fungi and protists. Their work, published in Frontiers in Microbiology, could have applications in changing how bacteria perform certain functions or react to changes in their environment.

• Glioblastoma (GBM) is a highly aggressive type of brain cancer. Even with current standard of care, 50% of patients die within 15 months of diagnosis. • This complex cancer is difficult to treat due to its location, structure, ability to spread quickly, high recurrence rate and severely limited treatment options. • GBM tumours can look identical under the microscope but respond differently to the same treatment. • With a national grant of about S$10 million, researchers in Singapore are working with overseas collaborators to address these challenges and develop new diagnostic and treatment options so patients can receive effective targeted therapy.

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.

The chances of restoring fertility through sperm stem cell transplant are as random as a coin toss. But a team of scientists developed a new strategy that serves as a “weighted coin” that can favorably rig the odds to achieve outcomes where fertility is successfully restored.

Researchers from Osaka City University find that when the larva nematode C. elegans is fed a diet of Bacillus subtilis var. natto, a bacteria used to ferment soy beans into the traditional Japanese food natto, upon reaching adulthood these worms are able to survive infections from the gram-positive bacteria Staphylococcus aureus and Enterococcus faecalis longer than when fed a standard diet of non-pathogenic E. coli.

Contributing to embryogenesis and pathogenesis through long-term in vivo molecular imaging 1. Development of a two-photon excitation light-sheet microscope which achieves low phototoxicity, an extended field of view, and high resolution for the observation of the growth of living organisms 2. Applications of the microscope demonstrate long-term time-lapse observations for a three-day span of the embryonic development of medaka fish

In collaboration with Kanazawa University, researchers from Osaka City University used high-speed atomic force microscopy (HS-AFM) to visualize at the nanometer level the movement of individual particles within the parasitic bacterium Mycoplasma mobile. After confirming the outline on the surface of the cell structure in an immobilized state with previous data gathered from electron microscopy, the team succeeded in visualizing the real-time movements of the internal structure by scanning the outside of the cell with HS-AFM.
Infants could identify two faces when the temporal interval between them was 800 ms, but they could identify only the first target (overlooked the second target) when the separation was 200 ms, thus demonstrating the attentional blink

Chuo University and Hokkaido University researchers have found that infants take less than a second to completely process visual information and have the same temporal limitation in processing visual information as seen in adults.

Tomohiro Mochizuki tracks down viruses inside single-cell organisms thriving in boiling hot springs. His fieldwork is conducted in relatively extreme environments and, despite the significance of his investigations, he doesn’t need many fancy gadgets back at his lab at Japan’s Earth-Life Science Institute (ELSI). ARN asked Mochizuki about his virus-hunting exploits and what they involve.

“By looking at substances in volcanos, lakes and hotsprings, you can start to see the ecosystems that existed billions of years ago,” says Mayuko Nakagawa, a microbiologist and specially-appointed assistant professor at the Earth-Life Science Institute (ELSI) based at the Tokyo Institute of Technology, Japan. She analyses components left by microorganisms with colleagues from various disciplines, while as a lab manager, she looks after cutting-edge equipment and visitors from different countries.
