In face-to-face conversations, speakers are continuously checking whether the listener is engaged in the conversation by monitoring the partner’s eye-gaze behaviors. The goal of this study is to build an intelligent conversational agent that can recognize user’s engagement from multiple types of eye-gaze information. In our previous work, we developed a… (More)
Organisms have seasonal physiological changes in response to day length. Long-day stimulation induces thyroid-stimulating hormone beta subunit (TSHβ) in the pars tuberalis (PT), which mediates photoperiodic reactions like day-length measurement and physiological adaptation. However, the mechanism of TSHβ induction for day-length measurement is largely… (More)

Temperature compensation is a striking feature of the circadian clock. Here we investigate biochemical mechanisms underlying temperature-compensated, CKIδ-dependent multi-site phosphorylation in mammals. We identify two mechanisms for temperature-insensitive phosphorylation at higher temperature: lower substrate affinity to CKIδ-ATP complex and higher… (More)
A novel fluorescent DNA probe containing pyrene-labeled C8 alkylamino-substituted 2'-deoxyguanosine was designed in order to discriminate single stranded and double stranded regions in DNA. This fluorescent sensor was used for the design of practically useful 3'- and 5'-ends free self-quenched molecular beacon (MB). Unique MB detectable by pyrene excimer… (More)
A novel quencher free molecular beacon was designed in which fluorophore-labelled pyrrolocytidine was placed away from the stem terminal. This new type of MB was used for the detection of a target DNA with an excellent efficiency.
A novel fluorescent oligonucleotide probe containing pyrene-labeled C8 alkylamino-substituted 2'-deoxyguanosine and a practically useful 3'- and 5'- ends-free self-quenched molecular beacons (MB) were designed. A unique MB detectable by pyrene excimer fluorescence was also demonstrated.
DNA can be concatenated by hybridization of DNA fragments with protruding single-stranded termini. DNA cleavage occurring at a nucleotide containing a DNA base analogue is a useful method to obtain DNA with designed protruding termini. Here, we report a novel non-enzymatic DNA cleavage reaction for DNA concatenation. We found that DNA is cleaved at a… (More)
Absolute values of protein expression levels in cells are crucial information for understanding cellular biological systems. Precise quantification of proteins can be achieved by liquid chromatography (LC)-mass spectrometry (MS) analysis of enzymatic digests of proteins in the presence of isotope-labeled internal standards. Thus, development of a simple and… (More)
We have synthesized various substituted 8-arylethynylated 2'-deoxyguanosine derivatives. Among them, acetyl substituted deoxyguanosine analogue 4c showed a remarkable solvent dependent fluorescence property, that is, an intense fluorescence in non-polar solvents but extremely weak fluorescence in polar solvents like methanol. By using solvatofluorochromic… (More)
