19–22 May 2022 Kyoto, JapanJuvenile Pacific bluefin tuna (Thunnus orientalis, PBF) are still small (about 20cm in fork length, FL) and so weak that even direct touch to the fish can cause fatal damage. Their vulnerability makes it difficult to collect vital data in the natural environment over the past years. We developed an operational instrument for smooth and quick attachment of tags. Fish was kept in the water even during the operation and we shorten the operation time to be 30-60 seconds. Also, the mechanical progress (archival tags downsized dramatically) contributed to the survival rate. The movement patterns of the juvenile PBF was investigated using the archival tags implanted in a fish during August in 2012, 2013 for 75, 62 individuals (18-33cm FL). Twenty one tagged fish were recaptured in total (recovery rate 15.3%), and we downloaded data successfully from eight of thirteen tags recovery. One tagged juvenile, which recorded for 79 days from August to October off Kochi (grew up from 24.5 to 50.0cm in FL). Our data showed that the tagged juvenile moved between coastal areas and offshore into the Kuroshio Current, thus the offshore coverage of their habitat could be restricted to the Kuroshio Current in their nursery areas.

Oral mucositis (OM) is a frequent adverse effect of allogenic or autologous hematopoietic SCT. It results from direct toxic injury to the mucosal epithelial cells by the immunosuppressive regimen. Here, we compared the incidence and severity of OM between a group of 24 patients who received proper oral management during hematopoietic SCT and a group of 24 who did not. The oral management group received pre-hematopoietic SCT instruction on oral care and an oral examination in the clean room. Differences in the incidence and severity of OM between the two groups were examined statistically. OM was observed in 14 (58.3%) patients in the oral management group and 22 (91.6%) in the control group. The median of the OM score was 1 for the oral management group (range 0 to 3) and 2 for the control group (range 0 to 3). There was a significant difference in the OM score (P<0.05) and in the incidence of OM between the two groups (P<0.01). This study shows that oral management may decrease the occurrence of OM. Our results also suggest that it is important to include an oral management provider on the hematopoietic SCT team.
