Wearable equipment supports human motion where and when needed

Wearable equipment supports human motion where and when needed

  A new model of pneumatic muscle and an active type of assistive equipment incorporating this pneumatic muscle has been developed at Hiroshima University and Daiya Industry Co. Ltd., Japan. This wearable equipment, called the Unplugged Powered Suit (UPS), supports human movement without requiring any electronic devices and tanks because it employs a newly developed… Read more

New approach allows better modelling of crucial economic activities over time

New approach allows better modelling of crucial economic activities over time

  Researchers in Japan and the UK and USA have developed a better method for modelling important kinds of economic data that may be useful for studying workforces, economic development, health, macroeconomics and other phenomena that vary over time. Dr. Kazuhiko Hayakawa from Hiroshima University and Professor M. Hashem Pesaran from the Trinity College of… Read more

Studying cancer DNA in blood may help personalize treatment in liver cancer

Studying cancer DNA in blood may help personalize treatment in liver cancer

  Fragments of cancer DNA circulating in a patient’s bloodstream could help doctors deliver more personalized treatment for liver cancer, Japanese researchers report. The new research may help address a particular challenge posed by liver cancers, which can be difficult to analyze safely. One serious risk of existing biopsy methods is that doctors who want… Read more

New model for hepatitis B helps identify potential new therapeutic approach

New model for hepatitis B helps identify potential new therapeutic approach

A promising new avenue for treating hepatitis B has been reported by researchers at Hiroshima University who have developed a new animal model of the disease. About two million people worldwide have been exposed to hepatitis B virus. Liver transplantation is often necessary to save the lives of patients who have severe liver damage that… Read more

Active deformations of cell nuclei contribute to intra-nuclear architecture formations

Active deformations of cell nuclei contribute to intra-nuclear architecture formations

There are two types of chromatin, euchromatin and heterochromatin, that vary with the stages of the cell cycle. In particular, euchromatin with rich active genes localizes to the interior of the nucleus during interphase; heterochromatin usually localizes to the periphery of the nucleus. Akinori Awazu, an Associate Professor at the Research Center for Mathematics on… Read more

Sendai virus defends against a threat

Sendai virus defends against a threat

A research group at Hiroshima University demonstrated the mechanism by which the Sendai virus (SeV) escapes the host immune system. The researchers examined the crystal structure of the complex of SeV C protein and transcription factor STAT1, and found that SeV C protein inhibits the signal transduction pathway of interferon gamma. This discovery will allow… Read more
