C-type natriuretic peptide (CNP), the third member of family, is thus far known to be distributed mainly in central nervous system and considered act as a neuropeptide, contrast atrial (ANP) brain (BNP), which cardiac hormones. Recently, we others have demonstrated that ANP-B receptor, selectively activated by CNP, localized not only but peripheral tissues, including blood vessels. This finding has made us speculate regarding production CNP. In present study, cultured endothelial cells were...

To study synthesis, storage, and secretion of brain natriuretic peptide (BNP) in the heart, we have measured BNP mRNA concentrations hearts Wistar-Kyoto rats also investigated its from isolated perfused heart. The atrium expressed gene at a high level, considerable amount was present ventricle, which corresponded to approximately 40% atrial concentration. When tissue weight taken into account, total content ventricle threefold larger than that atrium, although (ANP) only 7% atrium. By...

BACKGROUND Brain natriuretic peptide (BNP), as a cardiac hormone, is expressed together with atrial (ANP) in the ventricles congestive heart failure. However, ventricular expression of BNP hypertrophic cardiomyopathy (HCM) normal systolic function still unclear. METHODS AND RESULTS The study population consisted 39 HCM patients asymmetric septal hypertrophy and 10 control subjects without any specific disease. Eleven cases were obstructive (HOCM), other 28 nonobstructive (HNCM). All these...

Pneumococcal conjugate vaccines (PCVs) that are ten-valent (PCV10) and 13-valent (PCV13) became available in 2010. We evaluated their global impact on invasive pneumococcal disease (IPD) incidence all ages. Serotype-specific IPD cases population denominators were obtained directly from surveillance sites using PCV10 or PCV13 national immunisation programmes with a primary series uptake of at least 50%. Annual rate ratios (IRRs) estimated comparing the before any PCV each year post-PCV10...

The emergence and rapid spread of novel DS‐1‐like intergenogroup reassortant rotaviruses having the equine‐like G3 genotype (DS‐1‐like G3P[8] strains) have been recently reported from several countries. During rotavirus surveillance in Japan 2015–2016, three strains were identified children with severe diarrhea. In present study, we sequenced characterized full genomes these strains. On full‐genomic analysis, all showed a unique constellation including both genogroup 1 2 genes:...

Abstract After the introduction of pneumococcal conjugate vaccines, incidence infections due to meropenem-resistant serotype 15A-ST63 strains increased in Japan. By using whole-genome sequencing and comparing sequences with those clones from United Kingdom, States, Canada, we clarified traits clone. Our analysis revealed that Japan originated meropenem-susceptible Recombination site prediction showed strain-specific recombination regions included pbp1a pbp2b regions. A detailed composition...

Fusion regulatory proteins (FRPs) are newly defined cell surface molecules that enhance and/or induce virus-mediated fusion. Anti-FRP-1 Abs reacted with all of the established cells derived from humans and monkeys, whereas FRPs were found to be selectively expressed on a fraction monocytes in human PBMCs. Granulocytes no FRP-1 molecules, but approximately 18% granulocytes FRP-2 molecules. Alveolar macrophages also expression was enhanced by culture monocytes, CD14 not influenced cultivation....
