Previous studies suggested that increases in ocean heat content result in strengthening of tropical cyclone (TC) and causing the associated disasters. In the western North Pacific (WNP), acceleration of increasing rates of tropical cyclone heat potential (TCHP: ocean heat content above 26°C from the surface) in the TC rapidly intensifying (RI: a 24-h intensity change of ≥ 30 kt) zone may have contributed to increases in TC intensity. However, there is no research on the relation of the acceleration of increasing rates to the variations in TCHP in a climatological view, differently from the relation to decadal variations such as Pacific Decadal Oscillation (PDO). This study focused on the relation of the variations in TCHP anomalies (TCHPA) to RITCs over the past six decades. Although the annual mean TCHPA in the global ocean was not accelerated, the TCHPA accelerated recently in the late 1990s over the RI zone particularly in fall (October-December) in the WNP. The acceleration of the increase in TCHPA was possibly explained by the intensification of trade wind-driven ocean general circulation and the combination of the linear trend of TCHPA with PDO phase change.

Periodontal disease is a significant problem in companion animals such as dogs and cats. However, there is little information available about fimbriae association of periodontal disease in companion animals. In this study, we have purified and characterized a fimbriae from P. salivosa ATCC 49407. The molecular mass of this protein was approximately 60-kDa, as estimated by SDS-PAGE. Immunogold electron microscopy revealed that anti-60-kDa fimbrial serum bound to fimbria on the cell surface of P. salivosa ATCC 49407. However, fimbriae of P. gingivalis and P. gulae were not labeled with the same antibody. Immunoelectron-microscopic studies and immunoblot analysis revealed that antigenicity and molecular weight were distinct from previously reported Porphyromonas fimbrial proteins. The amino acid sequence of the N-terminal 15 residues of the 60-kDa fimbrillin protein revealed only 3 of 15 residues identical to other Porphyromonas species fimbrillin proteins. Thus, the N-terminal amino acid sequence of the 60-kDa fimbrillin protein of P. salivosa clearly differed from previously reported fimbrillin proteins. The level of adherence of the P. salivosa was 1.81%. It was confirmed that P. salivosa can adheres to human cells. These results suggest that the 60-kDa fimbriaeof P. salivosa ATCC 49407 is a new type of fimbria and may have an important factor in the adherence host cells. We suggest that the surface structure of P. salivosa may have a role in the colonization of this organism in periodontal pockets in companion animals.
