Promising candidates for the next-generation memory devices have emerged one after another for the last decade. Ferroelectric random access memories (FeRAM), magnetoresistive random access memories (MRAM), phase change memories (PCM) are indeed at the dawn of the international development races. Along with those three fascinating memories, we focus here on(More)
Distribution of photosystem II (PSII) extrinsic proteins was examined using antibodies raised against various extrinsic proteins from different sources. The results showed that a glaucophyte (Cyanophora paradoxa) having the most primitive plastids contained the cyanobacterial-type extrinsic proteins (PsbO, PsbV, PsbU), and the primitive red algae (Cyanidium(More)
The mode of action of the alkaloid veratridine has been reinvestigated on cultured cockroach neurones, which are normally inexcitable and do not have a detectable fast sodium current. The whole-cell and cell-attached configurations of the patch-clamp technique were used to record the macroscopic and single channel currents, respectively. Concentrations of(More)
There is a current upsurge in research on nonvolatile two-terminal resistance random access memory (RRAM) for next generation electronic applications. The RRAM is composed of a simple sandwich of a semiconductor with two metal electrodes. We introduce here an initial model for RRAM with the assumption that the semiconducting part has a nonpercolating domain(More)
Sodium tanshinone II-A sulfonate (DS-201) is a water-soluble derivative of tanshinone IIA, a main active constituent of Salvia miltiorrhiza which has been used for treatments of cardio- and cerebro-vascular diseases. DS-201 activates large conductance Ca(2+)-sensitive K(+) channels (BK(Ca)) in arterial smooth muscle cells, and reduces the vascular tone.(More)
Hagfishes are regarded as the most primitive living craniates. Excitation-contraction (E-C) coupling mechanisms were studied in skeletal and caudal heart muscle fibres of the hagfish Eptatretus burgeri. In white (fast) skeletal muscle fibres from the musculus tubulatus, force generation in response to electrical stimulation was maintained in nominally(More)
The protoplasmic drop isolated fromNitella became electrically excitable in an appropriate salt solution. Variations of salt composition and temperature in the external media induced discrete changes in the interfacial properties such as refractive index or surface tension, as well as in the electrical properties of the protoplasmic drop. Variation of salt(More)
Diphyid siphonophores swim using bursts of propulsive jets, which are produced by contractions of a monolayer of subumbrellar myoepithelial fibres lining the nectophore. This swimming behaviour is characterised by successive increases in the force generating the jets during the initial jets of the burst. Action potentials that generate the contractions(More)
Rhynchophylline (Rhy) is a pharmacologically active substance isolated from Uncaria rhynchophylla which has been used to treat cardiovascular diseases and has drawn considerable attention in recent years for its antihypertensive activities. We investigated the actions of Rhy on endothelium-denuded human mesenteric artery by tension measurement and its(More)
Scalp acupuncture (SA) therapy on strokes has been empirically established and widely used in clinics in China. SA is particularly effective at ameliorating paralyses and speech disturbances, and the recovery rate is twice that for those treated with medication alone. To investigate the effects of SA on a scientific basis, we have developed a new(More)
