Magneto-Absorption Spectra of One-Dimensional Ising Antiferromagnets in High Magnetic Fields(Magnetooptics)

We have performed magneto-absorption spectra measurements of the quasi-one-dimensional antiferromagnet RbFeCl_3.2H_2O with a hybrid magnet installed at High Field Laboratory for Superconducting Materials in Tohoku University

Acute intraabdominal hemorrhage from an aneurysm on uterine artery

A 36-year-old woman was underwent emergency laparotomy for acute intraabdominal hemorrhage, but bleeding points were not found. Abdominal pains continued after the laparotomy, and rupture of aneurysm on uterine artery was found in angiography. An transcatheter arterial embolization was done for the uterine artery, and the aneurysm was found to disappear in 4-day-after the angiography. Rupture of an aneurysm on uterine artery should be considered for the causes of acute intraabdominal hemorrhage

Photoluminescence of R-Lines in Alexandrite under High Magnetic Field and High Pressure(Magnetooptics)

The photoluminescence of R-lines due to the (CrO_6)^ center in alexandrite has been measured under pressures up to 15 GPa at room temperature and 77 K. The results show that the symmetry of the effective crystalline field, being orthorhombic at 1 atm, tends to become trigonal as pressure increases. To examine the influences of this symmetry change on the magnetic properties, the Zeeman spectrum has been measured under magnetic fields up to 15 T at 77 K. The Paschen-Back effect is found to develop under pressures near 8 GPa if the field is applied parallel to the b- and c-axes. This finding demonstrates that the character of the spins of the excited states involved in the R-lines changes as if it is transformed from the Heisenberg-type to the Ising-type. Some structural instability is suggested to occur above about 8 GPa at 77 K and about 11 GPa at room temperature

High-density lipoprotein cholesterol levels and cardiovascular outcomes in Japanese patients after percutaneous coronary intervention: a report from the CREDO-Kyoto registry cohort-2.

[Objective]To determine whether low HDL-C is a risk factor for adverse cardiovascular events in patients with known CAD. [Methods]We evaluated 10, 391 patients who underwent PCI from January 2005 to December 2007. In total, 3838 (36.9%) patients had low HDL-C (HDL-C <40 mg/dL in males and <50 mg/dL in females) and 6553 (63.1%) patients had normal HDL-C based on measurements on admission. [Results]The unadjusted 5-year incidence of major adverse cardiac events (MACE: composite of cardiovascular death, myocardial infarction or stroke) was significantly higher in the low HDL-C group than in the normal HDL-C group (17.6% vs. 14.0%, P < 0.0001). However, after adjusting for confounders, low HDL-C was not associated with a higher risk of MACE (adjusted hazard ratio [HR] 1.07, 95% confidence interval (CI) 0.97?1.19; P = 0.19). There was no significant interaction between the effect of low HDL-C on MACE and several subgroup factors including age, sex, clinical presentation of CAD, statins use, serum low-density lipoprotein cholesterol level, and serum triglycerides level. [Conclusion]Low HDL-C, as compared with normal HDL-C, was not associated with higher 5-year risk of MACE in patients who underwent PCI
