Chemicals releasing oviposition by an Asclepiadaceae feeder,Ideopsis similis, were identified from a host plant,Tylophora tanakae. A strong positive response was evoked by a methanolic extract of the plant, which proved to contain multiple stimulants. A mixture of two phenanthroindolizidine alkaloids, (+)-isotylocrebrine and (−)-7-demethyltylophorine,(More)
Improving an unhealthy lifestyle decreases risk of incidence and death of lifestyle-related diseases. Consultation about a healthy lifestyle to recipients of health checkups conducted by public health nurses is one method for such improvement. The objective in the present study was to investigate the difference between consciousness of intervention by (1)(More)
We report on a free-running single-photon detection at 941 nm using an InGaAs/InP single-photon avalanche diode (SPAD) operated with a passive quenching circuit. Adopting an avalanche signal height discrimination method, we can distinguish the photon-detection events from afterpulse noise events efficiently. The single-photon detection efficiency of 42 %(More)
High yields of viable pea protoplasts were produced from suspension cultured cells and the conditions for the optimum transient expression of the chloramphenicol acetyltransferase (CAT) gene fused to the CaMV 35S promoter after electroporation were investigated. Conditions for elicitor induction of a member of the phenylalanine ammonia-lyase (PAL) gene(More)
We demonstrated an efficient fiber-optic single-photon buffer (SPB) at 1550 nm. The SPB can control and give discrete time delays to a single-photon. Moreover the SPB is passively polarization-stable, and consequently the polarization-based quantum state of light can be maintained. The insertion loss of the SPB is as low as 2.98 dB, which indicates that it(More)
