Fractional flow reserve (FFR) is a useful modality to assess the functional significance of coronary stenoses. Although adenosine triphosphate (ATP) is generally used as the hyperemic stimulus, we sometimes encounter adverse events like hypotension during FFR measurement. Nicorandil, an ATP-sensitive potassium channel opener, recognized as an epicardial and(More)
In this study, we characterized prophenoloxidase (proPO, (PPO)) genes of Tribolium castaneum and examined their involvement in antimicrobial host defense. Amino acid sequence comparison with well-characterized PPO proteins from other insect species suggested that T. castaneum PPO genes encoded functional proenzymes, with crucial sequence motifs being(More)
OBJECTIVES We performed this study to evaluate the variability of fractional flow reserve (FFR) values which were measured from various methods of hyperemia induction. BACKGROUND Concerns have been raised regarding the variability of FFR due to different routes for hyperemic agent administration and different hyperemic agents targeting different receptors(More)
A behavior of an embedded system is designed by a state machine, which receives input events from externals through the interface, and sends output actions to externals through the interface. Thus the interface specification becomes major concerns in the system design. This paper describes a design method that defines the interface of a component by(More)
An ultrasensitive colorimetric DNA and RNA assay using a combination of enzyme-free click chemical ligation chain reaction (CCLCR) on dispersed gold nanoparticles (GNPs) and a magnetic separation process has been developed. The click chemical ligation between an azide-containing probe DNA-modified GNP and a dibenzocyclooctyne-containing probe biotinyl DNA(More)
We have previously demonstrated that the functional Toll and IMD innate immune pathways indeed exist in the model beetle, Tribolium castaneum while the beetle's pathways have broader specificity in terms of microbial activation than that of Drosophila. To elucidate the molecular basis of this broad microbial activation, we here focused on potential upstream(More)
Nuclear autoantigenic sperm proteins (NASPs) are members of the acidic histone chaperones, which promote nucleosome assembly. In humans, two splicing variants proposed for the somatic and testicular isoforms, sNASP and tNASP, respectively, have been found, and the shorter form, sNASP, reportedly promotes nucleosome assembly with the histone H3 isoforms,(More)
In this paper, we proposed a BGM assignment method to story segments using emotion dictionary. For segmentation of a story, we used information of characters appearing in a story. Changes of appearing characters and characters' sentiment information are used for segmentation. We prepared syntactic patterns for identification of characters and extraction(More)
Nasal lymphoma is the most common nasal tumor in cats and is generally a solitary and radiosensitive tumor. We retrospectively evaluated the response to radiation and survival time in relation to apoptosis and Ki-67 indices in feline nasal lymphomas treated with radiation therapy. The apoptotic and Ki-67 indices were evaluated with TUNEL and(More)
Plastic crystallinity of lithium salt, [LiB(OCH(2)CH(2)OCH(3))(4)] (1), and its solid-state ionic conductivity are disclosed. The addition of small amounts of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) to borate 1 led to the drastic increase of the ionic conductivity and lithium transport number of the electrolyte.
