One of the major sources of iron supply to the Okhotsk Sea and the Oyashio region, which both have high biological productivity, is thought to be regions of the East Sakhalin Current and its upstream, originating from the Amur River. This study suggests that the Soya Warm Current (SWC) region could also be a possible source of iron via resuspension of bottom sediments. We derived the volume backscatter strength from acoustic D...

Human pluripotent stem cells, such as human embryonic stem cells and human induced pluripotent stem cells, are used in basic research and various applied fields, including drug discovery and regenerative medicine. Stem cell technologies have developed rapidly in recent years, and the supply of culture materials has improved. This has facilitated the culture of human pluripotent stem cells and has enabled an increasing number o...

Chemotherapy-induced oral mucositis (COM) is a common adverse effect of cancer chemotherapy. Several clinical studies reported that repetitive use of mouthwashes containing 2.5–6.25% Hangeshashinto (HST), a Kampo formula, relieves COM, but the effect is insufficient. To solve this problem, we produced an oral ointment of 12% HST extract (considered quantitatively equivalent to 20% commercially available HST), which will increa...
