Enzyme improves colon health in rats An enzyme produced by fermenting a vegetable common in Japanese cuisine may be responsible for increasing the amount of at least one beneficial bacterium associated with healthy colons in a study using rats.  The results of this prebiotic research study will be presented at the International Conference on Nutraceuticals… Read more

How females store sperm: fertility study in chickens examines fatty acids

How females store sperm: fertility study in chickens examines fatty acids

The science of breeding chickens has revealed part of the mystery of how certain female animals are able to store sperm long-term.  Droplets of fat transferred from female cells to sperm cells may contribute to keeping sperm alive. Females of some types of insects, reptiles, and birds can store sperm from multiple males within specialized… Read more

A microbial metabolite of linoleic acid ameliorates intestinal inflammation

A microbial metabolite of linoleic acid ameliorates intestinal inflammation

Inflammatory bowel diseases (IBDs), including Crohn disease and ulcerative colitis, are hard to completely cure. Globally, IBDs affect more than 4 million people, today. However, Professor Soichi Tanabe (Graduate School of Biosphere Science, Hiroshima University) and his collaborators have demonstrated that 10-hydroxy-cis-12-octadecenoic acid (HYA), a gut microbial metabolite of linoleic acid, has a suppressive effect… Read more

What are the mechanisms of zooxanthella expulsion from coral?

What are the mechanisms of zooxanthella expulsion from coral?

Coral bleaching, which often results in the mass mortality of corals and in the collapse of coral reef ecosystems, has become an important issue around the world, with the number of coral reefs decreasing annually. Associate Professor Kazuhiko Koike and Ms. Lisa Fujise of the Graduate School of Biosphere Science at Hiroshima University and their… Read more
