Significant anomalous changes in the ultra low frequency range (approximately 0.01 Hz) were observed in both geoelectric and geomagnetic fields before the major volcano-seismic activity in the Izu Island region, Japan. The spectral intensity of the geoelectric potential difference between some electrodes on Niijima Island and the third principal component(More)
We studied the molecular evolution of H gene in four prevalent Asian genotypes (D3, D5, D9, and H1) of measles virus (MeV). We estimated the evolutionary time scale of the gene by the bayesian Markov Chain Monte Carlo (MCMC) method. In addition, we predicted the changes in structure of H protein due to selective pressures. The phylogenetic tree showed that(More)
We have previously reported that o^-adrenoceptor stimulation enhances adenosine-induced coronary vasodilation. In the present study, we tested the hypothesis that o^-adrcnoceptor activity exerts beneficial effects on myocardial ischemia through augmentation of vasodilatory effects of released adenosine. In open-chest dogs, the left anterior descending(More)
