室温強磁性有機材料に関する研究

Organic magnetic materials were fabricated by the arc discharge method with starting materials of nitrogen gas and triethylamine. After nitrogen gas or gaseous triethylamine was introduced into the chamber, an arc was　discharged between carbon electrodes with a purity of　99.99%. The as-made samples were annealed in　decreased air from 400°C to 10000e for 3 hours. The carbonaceous sample prepared in nitrogen gas was a diamagnetic material, while,the sample made from triethylamine was a ferromagnetic-like material whose magnetization was around 0.02 emulg at room temperature. After annealing between 500°C and 600°C, the magnetization of the ferromagnetic-like material increased by around 3 times as much as that of as-made one. However, the spin density, measured by electron spin resonance, decreased with increasing annealing temperature; in particular, it fell rapidly between 500°C and 600°C. Therefore, the linewidth of the ferromagnetic-like carbonaceous material after annealing at 500°C and 600°C was narrower than that of the as-made material, and the intensified spin interaction suggested an increase in the magnetization.textapplication/pdfdepartmental bulletin pape

Solar neutrino measurements in Super-Kamiokande-II

The results of the second phase of the Super-Kamiokande solar neutrino measurement are presented and compared to the first phase. The solar neutrino flux spectrum and time variation as well as oscillation results are statistically consistent with the first phase and do not show spectral distortion. The timedependent flux measurement of the combined first and second phases coincides with the full period of solar cycle 23 and shows no correlation with solar activity. The measured 8B total flux is (2:38± 0.05(stat.)/begin+0.16 // -0.15/end (sys.)) × 10^6 cm^{-2} s^{-1} and the day-night difference is found to be (-6.3 ±4.2(stat.)±3.7(sys.))%.There is no evidence of systematic tendencies between the first and second phases.journal articl

Assessment of genetic risk for myocardial infarction

application/pdfAlthough lifestyle and environmental factors influence the prevalence of myocardial infarction, genetic epidemiological studies have suggested that several genetic variants increase the risk for this condition. We have performed a large-scale association study to identify gene polymorphisms for reliable assessment of the genetic risk of myocardial infarction. The study population comprised 3,483 unrelated Japanese individuals (1,913 men; 1,570 women), including 1, 192 subjects with myocardial infarction and 2,291 controls. The genotypes for 164 polymorphisms of 137 candidate genes were determined with an oligonucleotide ligation assay based on analysis of fluorescent microspheres with suspension array technology. Multivariable logistic regression analysis with adjustment for age, sex, body mass index, and the prevalence of smoking, hypertension, diabetes mellitus, and hypercholesterolemia revealed that the 677C → T (Ala222Val) polymorphism of MTHFR, the 1595C → G (Ser447Stop) polymorphism of LPL, and the -108/3G → 4G polymorphism of IPF1 were significantly associated with the prevalence of myocardial infarction. A stepwise forward selection procedure demonstrated that IPF1, MTHFR, and LPL genotypes significantly affected the prevalence of myocardial infarction. Combined genotype analysis of these polymorphisms yielded a maximum odds ratio of 2.54 for the combined genotype of TT for MTHFR, CC for LPL, and 3G3G for IPF1. The genotypes for MTHFR, LPL, and IPF1 may prove reliable for assessment of genetic risk for myocardial infarction. Determination of the combined genotype for these genes may contribute to primary, personalized prevention of this condition.journal articl
